Description

Driving system for water jet blower

The present invention is relevant a kind of as claim 1 driving system for water jet blower as described in the preamble and the used method of this system operation.

To firing equipment, especially cleaning is at work mainly carried out with water jet blower to high-power steam boiler burner hearth, water jet blower provides the water jet of a pack to pass burner hearth and gets on the furnace wall on opposite.Under the thermal shock effect that produces,, cause peeling off of the foul formed by iron rust, slag and dust also because the kinetic energy of water jet and invade the cause of the right vaporization of Shuitu of micropore in the sedimentary deposit of furnace wall.The typical structural shape of this water jet blower and relevant technologies field are for example described in document DD276 335A1, DD281 452A5 and DD281 468A5.

The water jet that water jet blower comes out is followed a special predetermined path usually and is got to surface to be cleaned, is also referred to as jet mode, and wherein this path presents waveform or spirality, thus also can the cut-through thing, perforate or other sensitizing range.

Except that adopting template to control the transmission system, this template certainly leads to a very special jet mode, mainly also can adopt the twin shaft control mode, two Control Shafts are vertical mutually, horizontal positioned wherein, another root is vertically placed, so that can easily control the generation wave path.Adopt this mode, can control the drive unit of single shaft and produce specific waveform jet mode with the control of pure time or from the maximum impact that impacts of minimum all the time always up to today.

Yet this control mode requires as far as possible accurately to aim at transmission system as for example described in the document DD234479A1.At this moment at least two executive components act on the hydraulic giant, and wherein these two executive components are in 90 ° of ground and are configured on the support; One of the fixing point of these two executive components and hydraulic giant can level be positioned at same plane with the hinge that moves both vertically in addition, and this hinge is formed the motor point of hydraulic giant.

Also known a kind of twin shaft control mode from document WO 93/12398, it accurately controls hydraulic giant by two vertical mutually main shaft drives mechanisms of turning round.These two main shaft drives mechanisms support with a guiding trestle.

From the also known a kind of method that the clean surface temperature is controlled the water jet blower cleaning parameters of measuring that adopts of document DD239656A1.

In known water jet blower, the guiding of hydraulic giant is carried out with mechanical mechanism and central control mechanism, and wherein around jet guide, transmission and supporting member are supported and are configured on the supporting structure, and they have occupied very big space.Usually be that very long hydraulic giant of length and feed pipe have caused big lever ratio and power, they require corresponding guide rail, tumbler and support conversely again.

In addition, in each window area that a water jet blower is configured in primely wherein, always there are not enough spaces can be for utilizing.Many internal parts as steam pipe, switch cubicle, working face or the like, have all hindered putting into of big rectangle frame.

The objective of the invention is for water jet blower provides a drive system, it can be configured in space or even very limited place by flexibility, and it allows freely to select jet mode and movement velocity arbitrarily arbitrarily in addition.The present invention also aims to provide a suitable method to be used for operating this water jet blower.

This purpose is by reaching as the described a kind of water jet blower of claim 1 of the present invention and as the described a kind of method of claim 20 of the present invention.Favourable form of implementation and structure in each dependent claims, have been narrated.

As described in the present invention, the water jet blower that is used to clean firing equipment can be with at least one moving component motion, this moving component one end is connected with water jet blower, its other end then directly is connected with firing equipment.In addition, drive system is equipped with displacement transducer to be used for accurately determining the hydraulic giant position, can realize a kind of mode of advancing of control like this.

By a kind of like this structure, will follow a kind of new scheme, adopt this scheme can not rely on a supporting structure ground fully and guide water jet blower.

A kind of like this structure can be so that can utilize the space that water jet blower is configured on the firing equipment flexibly making full use of actual institute.In a kind of favourable structure, moving component is the part of a mechanical arm at least.One end of mechanical arm preferably is fixed on the firing equipment like this: make water jet blower consider to want and can be touched easily from the angle of safeguarding and checking, and be unlikely the place of unnecessary ground restraint of labour platform.But mechanical arm self is again a free posing, and wherein in a form of implementation, moving component is originally as mechanical arm.The end of one or more moving components is configured in the plane, this plane is not orthogonal to a vertical plane of forming by the hydraulic giant motor point again, can make this motor point further shift-in window or firing equipment forward like this, available thus drive system obtains bigger revolution range and more favourable lever ratio.If water jet blower is assembled on the horizontal top cover or base plate of a firing equipment, so-called vertical plane then is interpreted as the corresponding horizontal face by the motor point.If only use a moving component, then these parts preferably should be changeable on its length and direction and should satisfy the function of a mechanical arm substantially.If use two moving components, they only need the length drives device, so that hydraulic giant can be moved on free routing.

However,, so just no longer may drive hydraulic giant if, these two parts may occur and be positioned at a position of aiming at two moving components, or very difficult the driving.To such configuration mode, the 3rd moving component that can be used for supporting driving function is crucial.According to the stability of desired precision of motion and system requirements, also can take moving component more than three.

Identically concerning all aforementioned arrangements forms be: for example for carrying out a kind of corrugated jet mode, then need one or more moving components carry out high complexity, nonlinear motion, just can not consider use simple control, especially simple time control mode to such collocation form like this.

For this reason, drive system is provided with displacement transducer as described in the present invention, is used for the position of micrometric measurement hydraulic giant, and what relate to like this is basic control mode no longer just, but can adopt along the adjusting control mode of a setting moving line.Displacement transducer can be used to accurately control jet mode, so also controlled motion parts correspondingly.Drive system also can make some part of jet mode by inswept with one first speed, and for example unsoiled or responsive zone of the other parts of this jet mode is by inswept with a kind of second speed.The pattern of any injection and any rate curve basically all the mode of available position sensitivity programme or store.

Displacement transducer can be configured among the moving component itself as typical length or angular transducer, and perhaps they also can be configured on one or more displacement transducer arms.Importantly: their energy measurement hydraulic giants are with respect to the exact position of a reference position, this reference position is as being determined before injection program begins if possible, suitable make displacement transducer condenser type, inductance type or electromagnetic sensor arranged, also can be digital step-tube counter and similar device.

Control is carried out sharing in the formula electric-control system one, and its receives the measured value of displacement transducer, the value of setting of they and predetermined jet mode is made comparisons and controlled motion parts correspondingly.Like this, no matter what kind of one or more moving components space configuration mode is, jet mode all can accurately be repeated with respect to the path and the speed of operation.Moving component for example can be reciprocating piston hydraulic pressure, air pressure, or main shaft of knowing or rack and pinion gearing, also can be drive system electricity or magnetic, perhaps also can use a mechanical arm.According to getable space, also can preferably moving component be combined to adapt to the different condition in space with lever, rope cucurbit, chain, swing hinge etc.

Be to improve the availability of system and a kind of positioning accuracy and repeatability of jet mode, can provide than determining that in principle the required number of sensors in position Duos one displacement transducer at least.Even the method for employing error compensation can reduce the inaccuracy of displacement transducer and when a displacement transducer lost efficacy, also still can make equipment continue and can work.

A kind of method of moving system of the present invention is: equipment is installed to the scene, starts the water bundle of jet mode or eye-observation ejaculation then earlier with a template, the value that the displacement transducer that links so with it records just is stored.After displacement transducer is detected with respect to the measured value of some special reference point, just can be the value of setting of any jet mode displacement calculating sensor.

Therefore, the present invention can come one or more moving components are made almost arrangement arbitrarily according to the condition in place, although wherein need complicated Coordinate Conversion with displacement transducer controlled motion parts, still available predetermined rate curve comes the predetermined jet mode of accurate tracking.

Figure 10 and 11 is additional embodiments of hydraulic giant drive system;

Figure 12 and 13 is respectively rearview and the longitudinal section that band intercepts the hydraulic giant of medium and cleansing medium box.

The embodiment of Fig. 1～5 at first is used to illustrate the device form of water jet blower as described in the present invention.One window 2 is arranged on the wall 1 of a firing equipment, and inside angle Support 3 and outside angle Support 4 are arranged.The motor point 5 that hydraulic giant 6 is arranged in window 2, its form are that swivel bearing or spherical linkage are used for hydraulic giant 6 is fixed therein in the heart.Hydraulic giant 6 rear ends are equipped with fixing point 7.1,7.2 and 7.3, and moving component 8.1,8.2 and 8.3 ends near hydraulic giant one side rotatably are connected in said fixing point and go up (but can not move) on hydraulic giant.Moving component 8.1,8.2 and 8.3 rearward end then rotatably are connected on rigid bearing 9.1,9.2 and 9.3, and for example on the spherical linkage, water is to be that the feed pipe 11 of pressure-resisting flexible flexible pipe enters hydraulic giant 6 by a joint 10 and a form.

In actual conditions, firing equipment is then hindered the water jet blower mounted component by many and surrounds.For example, there are being a steam pipe 13 and rigid bearing 9.1 to be fixed on one first supporting member 12 on the window 2.One second supporting member 14 is configured in not far place, 2 the right near the window.Then be connected with a raster-like plate 15 on its right side, make platform as two.This second supporting member 14 has also limited handrail 16 and 17 and walk on stage and workbench 15 and be supported with a switch cubicle 18.

The hydraulic giant end is bearing in swingably with its moving component 8.1,8.2 and 8.3 vertical direction hunting range S neutralization its horizontal hunting scope from a left side " l " to right " r " from top " 0 " to bottom " u ".

Owing to barrier is arranged, in this scope, can not dispose frame structure.Because the distance 19 of the skins of steam pipe 13 and furnace wall 1 is very short, therefore the space that can utilize is very little, although this space can provide from top " o " the big vertical displacement of the hydraulic giant position of " u " to the bottom in workspace " S ", but only allow the displacement of minimum in the horizontal direction from skin 19 to 13 of steam pipes, because the obstacle that switch cubicle 18 forms, rigid bearing 9.3 only can be fixed on the switch cubicle, and since workspace S from bottom right hand (" r "/" u ") to left hand bottom (" l "/" u ") and left hand top (" l "/" o ") required big, be almost the displacement of level, must be fixed on the supporting member 14 the most right-hand edges, and also need a long moving component 8.3 thus.Between a 9.1-7.1 and 9.3-7.3, has place predetermined, controlled distance, each position of hydraulic giant and the preceding revolution of hydraulic giant is vicarious is all clearly fixed.The power of obtuse angle and growth only appears among workspace " r "/" o ".According to the present invention, be equipped with one the 3rd and be short movement parts 8.2 between 7.9 and 9.2 at point, it is controlled by its spacing simultaneously and can prevent that the vibration of hydraulic giant 6 and water jet and kick from moving.

Moving component 8.1～8.3 is operated in bench-top and rightmost side fringe region, and therefore do not hinder the passage of workbench, and can provide enough big space down and towards a left side, be convenient to allow water pipe head 10 directly be connected with an elbow 20 after the desired very short hydraulic giant length, and feed pipe 11 is disposed near the place on the left of the furnace wall for the water jet quality.Secondly like this, at first can obtain a less swinging distance, can obtain arriving the unobstructed passage of workbench 15, this point even in spraying the course of work, also can accomplish until injector to flexible water conduit.

As shown in Figure 1, on moving component 8.1～8.3, dispose control assembly, their according to predetermined jet mode and shown in the hydraulic giant positional value that records of displacement transducer 44 adjust the length of moving component.On all working position of hydraulic giant, each of moving component 8.1=8.3 all can change speed according to change and the length that the geometry of the geometric position of fixture 7.1～7.3 and rigid bearing 9.1～9.3 and angular relationship and distance is carried out length, their the interacting motion of hydraulic giant and guiding of water jet.One side of this external framework 14 has device 45 to be used to write down motion with the controlled motion parts.But the installation position of control device do not specify to be positioned at water jet blower near.Link to each other with water jet blower by suitable data being transmitted circuit 46, also this control device can be loaded in the Control Room, so that can promptly enable this control device.

In an embodiment as described in the present invention, after installing water jet blower, then measure the physical dimension between fixing point 7.1～7.3 on motor point 5, the hydraulic giant and the rigid bearing 9.1～9.3, the variation that measured result is admitted to a computer program and stores each motor element for predetermined jet mode according to the time of eject position and/or injection, and in the whole operation process, this change information is delivered to moving component through control assembly and gets on.

In another embodiment, set the stage in working range, the scotch (figure does not draw) that moving component surpasses the distance of hydraulic giant initial motion or is arranged in the hydraulic giant end can be set, and this scotch is bound up on one with mechanical system and regulates on the adjusting device of jet path.The variation that results from each moving component length of each motion of adjusting device and scotch is write down and is stored by displacement transducer, can adopt this adjusting device to be scheduled to any jet mode like this.Removing adjusting device and in control with after hydraulic giant puts into operation, stored motion just can begin.

Below be described in detail solution as described in the present invention with an example:

Water jet blower as shown in Figure 1 is after it installs, when hydraulic giant is positioned at a center, axially on motor point 5, should have following physical dimension and be used to adjust moving component 8.1～8.3, their rigid bearing 9.1～9.3 and the fixing point on hydraulic giant 6 7.1～7.3 are with respect to the position of the run-on point of supporting device for sluing mechanisms 5, and this fulcrum then is confirmed as geometric point 0 (among Fig. 4 and Fig. 5).

Certainly, Fig. 4 and Fig. 5 and in the table given coordinate be only applicable to point-like and execute turning point, for example, with the form of spherical linkage.Fig. 1,2 and Fig. 4,5 shown in band eye shape and the simplified application of ring-type Connection Element in, may still need to do correction to the point of rotation.Yet these corrections are to be determined by test, because to all mechanical movements of moving component, be necessary a margin of tolerance.

Adopt coordinate X; Y; The point of rotation of Z=0, motor point 5, the coordinate that then can come to determine zone, furnace wall to be cleaned like this with and limiting value: how much straight lines (if possible to big distance after the trajectory correction of having made water) of getting to the water jet of the lip-deep hydraulic giant 6 in firing equipment furnace wall have determined (relevant with each the hydraulic giant position) geometric point on the furnace wall.

Fig. 3 illustrates the physical dimension of a combustion chamber part.In its underpart, 6 burner mouth B are arranged, 6 have flue gas resorption mouth R at an upper portion thereof.The installment state of the hydraulic giant 6 shown in Figure 4 and 5 shows its geometric point O in the drawings.To plane Y=0, then on chamber wall, produce from Gr through the horizontal-jet region S to G _LThe injection boundary.To plane X=0, then produce from G _oThrough S (said herein " on ", " right side " ... Deng being logic arrangements of Figure 4 and 5 being taked mirror version all) limit point G _uAll can on how much, be associated at any one the other point on the chamber wall with a coordinate of hydraulic giant position.In a preferred embodiment, this point on how much, adopt existing combustion chamber yardstick, such as realizing by a mathematical routine.

In other embodiment, the characteristic point of chamber wall adopts position measurement to determine, for example adopts laser beam to substitute the hydraulic giant position.These laser beams are used (must consider the elongation of surface, furnace wall vertical, horizontal in the boiler course of work in this case certainly) when boiler remains static, perhaps also can use the measurement mechanism that can be used under the continuous firing state.

Similarly, how much last methods available mathematics or measuring technique of the jet path of surf zone to be cleaned are determined and are input in the control system of moving component.An example of this respect is illustrated among Fig. 3, be used to clean be positioned under some flue gas resorption mouth R and flue gas resorption mouth on the burner hearth deposition.Cleaning procedure starts from A, ends at E.Working method is: after relevant path one time functional arrangement is programmed, for example in a computer or single-chip data memory, do this programming, after the instruction of input corresponding cleaning, water jet blower moves forward into position A (Fig. 3), and along with opening of feed pipe, the path one time function program of moving component 8.1～8.3 be performed until an E and this time cut off supply channel again.

That Fig. 6 and Fig. 7 represent is another embodiment, wherein show one have 2 bent angle arms and a control device the shortening formula, therefore also be to be easy to the water jet blower that moves especially.On the furnace wall 1 of firing equipment window 2 is arranged, it has inside angle Support 3 and outside angle Support 4.In window 2, the motor point 5 of hydraulic giant 6 is fixed to install and be configured to preceding floating bearing and is used for hydraulic giant 6 is fixed in the heart.Hydraulic giant 6 has fixing point 7.1 and 7.2 in its back-end, and the end of moving component 8.1 and 8.2 close hydraulic giant one side is rotatably connected on the said fixing point.Moving component 8.1 and an end backward of 8.2 then are rotatably connected in rigid bearing 9.1 and 9.2.It is to carry out for the feed pipe 11 of pressure hose form by a connector 10 and that water enters hydraulic giant.Moving component is fixedly connected on the support, can very water jet blower be installed simply like this, and according to different construction forms, also can save support need not.

Hydraulic giant 6 and water swivel 10 are assembled in the spherical container 20, it is used as the stable volume of lateral stream, moving component 8.1 and 8.2 each by a upper arm 21.1 and 21.2 and the crooked shape underarm 22.1 and 22.2 that is fit to spherical volume 20 form, they link to each other with 23.2 with rotating disk 23.1.

Rotating disk has drive unit 25.1 and 25.2, and they enter switch board 18 via flexible cable jockey 26.1 and 26.2.Switch board 18 and rigid bearing 9.1 and 9.2 are fixed on the support 27, and this support is configured on the furnace wall 1.In the embodiment of this water jet blower, only can adopt four/once support and two moving components 8.1 and 8.2 are can be with total one-sided is installed in 1/4th the area with exceeding window, bottom section and left part just all can be approaching by an operator 28 like this.Particularly, adopt this mode can reasonably use existing holder part on the firing equipment, so that can obtain an assigned position of water jet blower.

The extremely short hydraulic giant 6 of length has a spherical container 20 as described in the present invention like that in its end, its balance feed pipe 11 flows into the flow proportional in the spherical container and the uniform flow who flows into (operating) water nozzle once the hydraulic giant cross section is provided.Adopt the moving component 8.1 and 8.2 of this collocation form, and the fixture 7.2 and 7.2 with small-scale structure, required lever ratio then diminishes and only needs 2 moving components just can obtain the stability of hydraulic giant guiding.Although physical dimension diminishes, adopt the lever system bend outwards still can with drive unit 25.1 and 25.2 and switch board be configured in the space of support 27.Because as the motor point 5 of the point of rotation with the distance between fixture 7.1 and 7.2 is dwindled and the controlled motion of arm 8.1,8.2 and cable connecting arrangement 26.1 and 26.2 also shorten thereupon, make like this can be big the shared space that reduces.

In another kind of solution, only adopt that the hydraulic giant guidance quality problem of the moving component of two length controls is to solve by additional 1～2 moving component unsteered, tension, they for example are that the rope of the band counterweight of rolling via roller is (referring to Figure 10 and 11: position 8.2,9.2,29).It is described that its working method is followed in Fig. 1～4 first example.

Fig. 8 and Fig. 9 illustrate structure and the drive unit that another embodiment is used to shorten as one of moving component with the bent angle arm of 3 balanced configurations the formula water jet blower.Band is arranged towards the angle Support 3 of inside with towards the window 2 of the angle Support 4 of outside on the wall 1 of firing equipment.In window 2, fixedly mounting motor point 5 and be constructed to before floating bearing as during hydraulic giant 6 is fixed in the heart.Hydraulic giant 6 portion in its back-end has fixing point 7.1,7.2 and 7.3, and moving component 8.1,8.2,8.3 rotatably is connected on the said fixing point near the end of hydraulic giant one side.The end backwards of moving component 8.1,8.2,8.3 then is pivotally attached on rigid bearing 9.1,9.2 and 9.3.It is to be undertaken by the feed pipe 11 that a joint 10 and is shaped as the pressure-resisting flexible flexible pipe that water enters hydraulic giant.Each forms moving component 8.1～8.3 by a upper arm 21.1～21.3, underarm 22.1～22.3, and each all has a rotating disk 23.1～23.3, and they all are equipped with the angle regulator (not shown).Hydraulic giant 6 enters-180 ° the section of turning to 24 from its rear end, this section of turning to is linked on the elbow 20.Adopt the benefit of this solution to be: the bending by this upper arm-following arm-type structure makes note that fixing point 7.1～7.3 approaches slewing equipment as the motor point 5 of the point of rotation 0 and still be positioned within the outside angle Support 4 and work, and fixing point 7.1～7.3 in working range S path length and the corner of the rotating disk 23.1～23.3 that causes thus also be reduced to minimum.

Thus the further shortening (not shown) of the length of water jet blower 6 and upper arm-following arm system 22-23 1 further to dwindle as described below also be possible: rigid bearing 9.1-9.3 directly can be configured on the edge, outer of outer angle Support 4, it is also reduced further that total only exceeds the required motion of the size of window and feeding conduit flexible hose slightly.Described mode was carried out before the adjustment of working range was similar to.The change in path will be changed Δ α and be substituted by the corner of rotating disk 23.1～23.3.

Figure 10 and 11 illustrates the embodiment of the water jet blower with 2 movement parts that tangentially connect firmly and a hydraulic cylinder.

Rope shape moving component 8.1 and 8.3 and they rigid bearing 9.1 and 9.3 and tourelle 42 be configured to level of approximation, but on the tangential outer wall area of opposite hydraulic giant 6 outer tubes 35 that are connected to angle Support 4 inside with installed part 7.1 and 7.3 with aforementioned schemes.8.2 of moving components are configured to a hydraulic cylinder, and its rigid bearing 9.2 is positioned in the supporting of palisade base plate 15, and this moving component is connected to the place of close air supply pipe 38 on the hydraulic giant with its fixing point 7.2.Pneumatic fitting 38 and water swivel 11 are configured to axially form backward, and its bend is jointly upwards towards same direction.The air supply not only as intercepting air and scavenging air, also is used as cooling agent owing to its guide functions at this simultaneously.

This configuration mode brings following advantage :-moving component 8.1 and 8.3 move distance are little, and roller 42 only needs little corner like this.-by tangential fixing point 7.1 and 7.3, especially be free air cooling but the big diameter of (air supply pipe) situation lower outer pipe 35 improved the situation of power effect.-the simplification that connects by a hose clamp 43 the common medium of water/gas supply with, and reduced required space.Although-adopt cable traction effect 8.1 and 8.3 and adopt hydraulic cylinder 8.2, still obtain more reliable guide effect.

Embodiment shown in Figure 12 and 13 has illustrated that how water jet blower is protected by means of protective sleeve utilization obstruct and purge gas and cooled off, and for example makes it motion with three cord-like moving components.A kind of like this shortening type structural form that hydraulic giant has near the parallel water supply line of furnace wall, particularly similar and wall can be gone it by relative better and fully the threading in the housing, can make all driver parts avoid pollution like this.Only need feed pipe and measurement and the protruding housing of pilot are laid.Guidance mode as the different fluid that described in detail with reference to the accompanying drawings can be carried out realization therein, can reach cooling, anti-pollution (cleaning) so simultaneously and stop purpose by the gas exchange (obstruct) that does not add control of window.For preventing that especially exit region is subjected to the infringement of foul and corrosive gas, the mode that available cleaning agent is taked to shield injection to this zone gets around the formula cleaning.

Of the present invention another important aspect in (this aspect also can be independent of the present invention other feature and adopt current technical merit on equipment, to be implemented), can intercept and the supply side of cleansing medium is further improved.This point reaches like this: the supply of obstruct and cleansing medium is not a continuously adjustable, but each water jet blower is regulated separately.This point both can be carried out centralizedly supply to a plurality of housings by suitable valve and be carried out, and also can carry out single supply and realizes by correspondingly regulating the supply unit.

Differential pressure between firing equipment inner space and the enclosure interior space is particularly suitable for doing the measurement and the controlled quentity controlled variable of medium barriers function.If keep this value constant, then gas will never from firing equipment flow into housing and make obstruct MEDIA FLOW firing equipment remain on consistently all the time acceptable low-level on.

Be suitable for the measurement of medium cleaning function (or refrigerating function) and controlled quentity controlled variable especially before hydraulic giant in the head region or the temperature value on the other one or more measurement points in motor point.If keep this point constant, although then the amount that cooling medium is required can change along with the variation of condition of work, just on the desired degree of cleaning function.

These two kinds of regulatory functions also can combine carries out, and at this moment for example keeps differential pressure constant earlier, gets on but when exceeding a temperature limit value function is switched to temperature adjusting.

On the furnace wall 1 of firing equipment, window 2 is arranged, wherein have towards inner 3 angle Support 3 with towards the angle Support 4 of outside.In window 2, be connected with motor point 5 and be configured to before floating bearing in order to during hydraulic giant 6 is fixed in the heart.Hydraulic giant 6 portion in its back-end has fixing point 7.1,7.2 and 7.3, and the end of moving component 8.1,8.2 and 8.3 close hydraulic giant one side is connected on the said fixing point with being rotated.Moving component end backwards is rotatably connected on rigid bearing 9.1,9.2 and 9.3.It is to carry out for the feed pipe 11 of pressure-resisting flexible flexible pipe form by a joint 10 and that water flows into hydraulic giant 6.Do not add detailed description, non-rotatable but fixture 7.1～7.3 flexible maintains stable and flexible rope, they are used as moving component 8.1～8.3.Rope rolls on rigid bearing 9.1～9.3 through roller, perhaps by around/be deployed on these rollers.In another embodiment, in the end of the rope of moving component 8.2 counterweight 29 (being represented by dotted lines among the figure) is arranged.Roller has drive unit 25.1～25.3 and supporting member thereof.Window 2 is limited by a terminal box 30.The outer of terminal box is by the free inner space 32 through a housing 31 and a circulation of air that hydraulic giant 6 seals and forms.Hydraulic giant 6 and nozzle 33 thereof have an inlet 34 in the end.Hydraulic giant by 35 of outer tubes around.This outer tube has a stripper loop 36, and its zone that is in advance forms the gas cabin 37 of a band gas inlet pipe 38, and the zone forms a water section of turning to 39 in the back, and this turns to Duan Ze to lead to water interface 10.

Obstruct and washing fluid (being preferably air) can flow into inner spaces 32 via the nozzle head of perforate 40 37 inflow hydraulic giants from the gas cabin and through perforate 41.Adopt this kind solution, 3 moving components 8.1～8.3 are just controlled by pulling force.The twisting resistance that is caused by the spatial movement of moving component is compensated by a rope especially, this rope be expressed as in the drawings with rigid bearing 9.3 on tourelle 42 combine.In another solution, roller and rope then chain and sprocket wheel substitute.In this scheme, as shown on rigid bearing 9.1 like that, chain can freely hang down at its free end.

In another solution, a moving component (as the moving component of representing with chain-dotted line here 8.2) is not equipped with drive unit, and required tension then produces through a roller 9.2 and counterweight 29.

In this scheme, air feed and feed pipe can be put into a sleeve pipe, air feed and feed pipe freely hang, and are configured in the vertical plane, and its moving component and air feed, feed pipe on rotary position do not hinder mutually.Elongated rope is used as moving component (they also only require very little fixture 7.1～7.3), outside fixture is swung into for the requirement in the design within the angle Support 4 time, even when hydraulic giant is positioned at allowable angle of inclination, still provide enough spaces for hydraulic giant 35 of housing 31 and hydraulic giant outer tubes.In this case, can further shorten hydraulic giant.

Although outer tube 35 adds the hemisphere of sealing provide the balanced flow condition that enters hydraulic giant as the section of turning to 39 and guaranteed that the hydraulic giant shortening still has a water jet no vortex, less divergent shape.

Certainly also the technical scheme of introducing so far can be mutually combined, particularly this point is suitable for selecting to be configured in place, the installed part of dried up rifle motor point 5 different distance different form such as spherical linkage, lapping plate, eye joint, hinge, universal joint with the dynamic action of aggregate motion component technology and their pulling force and/or pressure, with installed part or needs the rigid joint etc. of flexible adaptor, selects the moving component of different length and rigid bearing is configured in the different location.Another advantage of doing like this is can equip single parts to go to firing equipment, for example: the water jet blower of moving component, shortening or the displacement transducer of tape controller or a whole set of water jet blower.A kind of favourable method for providing should be for example carries out on a kind of known water jet blower type (described in document WO 93/12398 the sort of) in a manner described below.In a wall, for example in the scope of a raster-like base plate, the window of the inside and outside angle Support of a tool is arranged.Hinged hydraulic giant is thereon guided by a spherical linkage in window.(being cemented on the inside angle Support of furnace wall) on the support, the main shaft that is bearing on the support is all arranged up and down, they are used as the hydraulic giant moving component.Last main shaft is rotated by the drive unit that a band displacement changes system/corner change system.Bearing is housed again on main shaft, and its guiding one is the parts that move both vertically of main shaft form.This vertical major has a band displacement to change the drive unit that system/corner changes system equally.The one fixing fixing point of hydraulic giant is arranged on this vertical major.By hydraulic giant being connected on the spherical linkage in the window and being connected on the fixing point of the parts that move both vertically, the direction of water jet blower water jet is changeable.This water jet blower can be reequiped now, and it can replace long hydraulic giant and be made into shape shortening, crooked, additionally has a glomerate balance volume.In addition, the also available case cover of water jet blower gets up to be used for dustproof and anti-spraying.Moving component is equipped with displacement transducer, and these sensors link to each other with a controller again.The drive unit of moving component is guided by controller again.The reduction of this bulk of water jet blower with and the shell that covers make the operator can be easily, zero defects is jeopardously near a raster-like base plate.A kind of modifiable, can implement different arbitrarily jet modes with the drive unit that displacement transducer is connected with control device.

Equally, the method for selecting the control jet mode with and the establishment of program can in the solution of experiment measuring technology and mathematics programming technique, at random be made up mutually.For example, can the method utilization by measuring technique or experiment spraying the geometric figure size, to prolong in the firing equipment guiding of hydraulic giant long, determine as on the maximum/down, geometry corner points such as a left side/right side, and these data are imported a mathematical routine, and after this be used to calculate the required further track point of jet mould formula.

Another kind of modification is to carry out the spraying that former scheme is irrealizable so far, have different paths degree, like this position of serious fouling can be sprayed by the water that pre-programmed they carries out time expand, and need not to close or connect water supply valve at high speed, thereby can not interrupt the spraying (see figure 3) from terminal point E to starting point A of next jet mode.

Adopt the present invention to have the following advantages:

A. this method guarantees to implement arbitrarily different jet mode, it at first do not stick to the level with 90 ° of change amounts and/or move both vertically, the geometric format of the conventional components of circumference or screw. The direction of motion, turn to and to be changed arbitrarily with speed and can adjust separately the requirement of cleaning to be fit to.

B. to the infield of water jet blower without any restriction. Have obstruction window, space not enough and configuration mode and the length of the factors such as obstacle in some other space by changing moving component, select fixing point on the hydraulic giant and fixture all can be overcome respectively to be used to install suitable water jet blower. Like this, an optimal selection can be arranged in that water jet blower is configured on the firing equipment, and the water jet blower number on firing equipment can be reduced to minimum.

C. the material therefor amount, all can be reduced the demand in space and the weight of water jet blower. Can omit especially the bearing and the transmission mechanism that are contained on one stable, the big frame, and used main shaft, chain and guide rail in the scheme in the past. Simplified installation.

D. because structure member is not had the requirement of fixed dimension aspect, thus material raise the quite flexible that becomes. The common commodity section that provides does all can arbitrarily be used as moving component, rigid bearing and control element on the market.

When e. producing fault, when replacing member, can allow structural deviation, if jet mode is adjusted suitable.

F. the size of the size of water jet blower, especially rear portion and side direction is reduced. Even concerning small-sized platform, also device can be installed in top like this and easily near it.

G. way of supplying water is simplified, and owing to reduced the swing path and omitted bend, has therefore reduced the incidence of fault.
