Definitions

the present invention relates to a pile driver, in particular for pile probes, according to the preamble of claim 1.
Such ramming probes in contrast to drilling probes, can be carried out very easily and inexpensively, since ramming devices have a simple structure and are also easy to use.
Piling equipment of the type mentioned above are known. They essentially have a frame which is equipped with guides in which the ram is guided and with a chain for lifting the ram. If the chain is endless and formed over deflection rollers, it has drivers which are designed as rod elements which are connected to the chain and protrude at right angles therefrom.
the chain is located on the outside of the frame and parallel to the guides for the ram and outside the ram.
the ram is provided with a bracket in which the bar element of the chain engages coming from below and pulls the ram up. This is due to the weight of the ram and the lever arm of the bar element a moment which acts on the chain and which must be absorbed by the chain by suitable devices.
the chain is guided over a deflection roller.
a similar pile driver is known, for example, from GB-PS 1 486 002, which is provided for driving piles.
This pile driver has a frame in which the ram is guided. Outside the frame there is an encircling chain which is equipped with drivers which protrude above the chain and interact with the ram when it is being pulled up, so that a moment is also exerted on the chain, which also causes the above-mentioned disadvantage. An adjustment of the fall height of the ram is not provided for in this ramming device.
the object of the invention is to design a ramming device, in particular for ramming probes, so that the ram to be pulled up is held securely by a driver, and that the ram is at a selectable and easily adjustable height by the driver is released and slides down the guides to strike the rod of the probe to be driven.
the object is achieved by the features specified in the characterizing part of claim 1.
the guides of the frame consist of two U-profiles, the legs of which are directed towards each other so that the carriage can be arranged between the U-profiles, and the guide rollers are supported on the inside of the legs .
the parallel, endless means are also arranged between the U-profiles, the slide in front of and behind the latch mechanism, which is arranged in the central region of the slide, has openings through which the front run and the rear run, respectively of the two endless means.
the carriage is advantageously equipped with a holding device which comes to lie outside the profiles and on which holding device a weight is releasably attached, which is easily exchangeable for another weight.
the weight connected to the holding device of the slide is provided with an opening through which the rod to be rammed into the ground is guided with play.
a detachably fastened, flange-shaped part is arranged on the rod, on which the weight strikes.
the latch mechanism consists of a slide which has an integrally formed latch, which can be moved between the endless means and comes to rest in the area of action of the drivers.
the slide is pressed into this position by spring force.
the release is carried out by a pivot lever, one leg of which is coupled to the slide, and the other leg of which is equipped with a roller which runs onto a wedge which is attached to the guides in a height-adjustable manner. This ensures an inevitable and therefore safe release at the selected height.
a further advantageous embodiment of the invention consists in that the position into which the slide is pressed by means of spring force and which corresponds to the driving position can be adjusted by an adjustable stop.
the endless means can be equipped with several drivers, the area of which is which the pawl of the slide comes to lie to raise the slide, have a different distance from the slide.
the stop which limits the front position of the slide, it can be caused that the carriage is pulled up by every driver, or by every second driver or, for example, only by every third driver that runs past the carriage. In this way, for example, the stroke frequency can be changed depending on the height of the slide.
the wedge on which the swivel lever runs to pull back the slide and to release the slide is held in the longitudinal direction by means of a clamping device on the profiles.
the clamping device on which the wedge is arranged is coupled to the slide in such a way that with each impact that the ram exerts on the rod to be driven in, the wedge is pulled by the amount by which the rod penetrates into the ground. This automatically ensures that the fall height remains the same regardless of the penetration of the bar into the ground. This is particularly important if the depth of penetration of the probe is recorded as a function of the energy provided, in order to draw conclusions about the nature of the soil.
the pile driver 1 according to FIG. 1 is composed of a frame 2, the guides 3 for the slide 4 of which are formed from two parallel profiles 5, 6 in the form of U-profiles.
the profiles 5, 6 are connected to one another at their upper and lower ends by means of transverse webs 7 and 8, respectively, in such a way that the legs 9 and 10 of the two profiles 5, 6 are directed towards one another and that the profiles 5 and 6 are spaced apart from one another .
the frame 2 is provided with a base 11, which serves as a base.
a pair of guide rollers 12 and 13 is rotatably supported.
a first endless roller chain 16 is guided over the first deflection rollers 14 and 15 of the two deflection roller pairs 12 and 13, which are designed as chain wheels.
a second endless roller chain 19 is guided over the two second deflection rollers 17 and 18 of the two pairs of deflection rollers 12 and 13, which are also designed as sprockets.
the first deflection rollers 14 and 15 are connected to the second deflection rollers 17 and 18 in a rotationally rigid manner at a distance from one another.
the deflection roller pair 13 is driven by a motor 20 which is attached to the base 11. This motor 20 is designed as a hydraulic motor, the speed of which is variable.
the carriage 4 which is guided in the profiles 5 and 6, as can be seen from FIGS. 2 to 4, is provided with a latch mechanism. As a result, the carriage 4 can be pulled up by the two roller chains 16 and 19, between which drivers 21 are fastened.
the carriage 4 has a holding device 22, from which a weight 23 is received.
the weight 23 is detachably connected to the holding device 22, so that it can easily be exchanged for another weight.
the weight 23 has an opening 24 through which the rod 25 to be rammed into the ground is guided with play.
the notch of the carriage in its upper position takes place via a wedge 26, which is held in the longitudinal direction by a clamping device 27 on the profiles 5 and 6.
the clamping device 27 consists of a support plate 28, which is equipped with guide grooves, not shown, into which the legs 9 and 10 of the profiles 5 and 6 protrude, so that the clamping device 27 is guided.
the clamping device 27 is clamped to the profiles 5 and 6 by means of clamping brackets 29 which are resiliently fastened to the support plate 28 and press against the surface of the legs 9 and 10 of the profiles 5 and 6. As a result, the clamping device is held in the corresponding position by friction.
the support plate 28 has on the upper and lower edge each a right-angled tab 30 and 31, which are provided with holes through which a rod 32 is passed with play.
the rod 32 is fixedly connected to the carriage 4 at its lower end.
the upper pair of deflection rollers 12 can be mounted on a bracket 34, which is adjustable in the longitudinal direction with respect to the frame 2 by means of adjusting screws, not shown. As a result, the roller chains 18 and 19 can be retensioned.
Fig. 2 the position of the carriage 4 is shown when it is in the lower position.
the weight 23 rests on a flange-shaped part 35 which is attached to the rod 25, which is to be rammed into the ground, for receiving the stroke.
the holding device 22 is detachably connected to the carriage 4 by means of screws 36.
the carriage 4, which is box-shaped, is provided on both sides with four guide rollers 37, which are supported on the inside of the legs 9 and 10 of the profiles 5 and 6, so that the moments that occur when the carriage 4 is raised and when it strikes arise, be included.
a bush 39 is fastened to cross members 40.
the upper part of the sleeve 39 is with a Provide slot 41 through which a leg 42 of a pivot lever 43 projects.
the pivot lever 43, the other leg 44 is equipped with a roller 45, is pivotally mounted on the box 38 by the bolt 46.
the leg 42 engages with its end facing away from the bolt 46 into a recess 47 in the slide 48.
the slide 48 is displaceable in the bush 39 by the pivot lever 43.
the pawl 49 is integrally formed on the front end of the slide 48.
the pivoting lever 46 is pulled into the position shown in FIG. 2 by the spring force exerted by the tension spring 50. This position is limited by the stop 51, which is held adjustably by a screw thread in the bush 39.
the pawl 49 projects between the roller chains 16 and 19, which form the front run 52 in this area.
the direction of rotation of the lower pair of guide rollers 12 causes the front run 52 of the roller chains 16 and 19 to move upward.
the driver 21, which is fastened between the roller chains 16 and 19, abuts the pawl 49 with its upper contact surface, the carriage 4 is raised.
roller chains 16 and 19 continue to run, the driver 21 bypasses the upper pair of guide rollers 13, passes through the rear run 53 and the lower pair of guide rollers 12 again under the pawl 49 of the slider 48, which are now again in the dash-dotted, front position lie, whereby the process is repeated.
a plurality of drivers 21, for example four, can be attached along the roller chains 16 and 19, which are at a constant distance from one another. This means that four strokes and consequently four strokes are carried out while the speed of the motor 20 remains the same during one revolution of the roller chains 16 and 19. The waiting time for the carriage 4 when the stroke has been carried out is reduced considerably until the next driver 21 can pull the carriage 4 up again. This is particularly advantageous for small heads.
the box 38 of the carriage can be seen.
Four stub axles 54 are mounted on both sides of the box 38, on which the guide rollers 37 are rotatably mounted.
the guide rollers 37 roll on the inside of the legs 9 and 10 of the profiles 5 and 6.
the box 38 is provided in front of and behind the latch mechanism with an opening 58 and 59 through which the front run 52 and the rear run 53 of the roller chains 16 and 19 pass.
roller chains 16 and 19 are guided in the area of the carriage 4, so that no evasive movement of the roller chains 16 and 19 can take place, in particular in the area of the pawl 49, which in particular could occur when the roller chains 16 and 19 are no longer optimally tensioned. This also ensures that the pawl 49 is securely latched to the driver 21 in this case.
a driver 21 can for example consist of a full piece 55, while the other driver 21 consists of a U-shaped profile piece 56. Due to the fact that the front position of the pawl 49 of the slide 48 can be adjusted by the adjustable stop 51 (FIGS. 2 and 3), depending on the position of this stop, it can be achieved that only the drivers 21, which are equipped with a full piece 55, cause the carriage 4 to be pulled up while the driver 21 with the U-shaped profile piece 56 does not come into contact with the pawl 49.
the stop 51 can, however, also be set such that both types of driver 21, both with the full piece 55 and with the U-shaped profile piece 56, cause the carriage to be lifted up.
This piling device which allows a fall height of around two meters and whose drop weight is a maximum of 200 kg, can be easily operated by a single person, since the safety of the work processes is guaranteed.
the base 11 of the pile driver 1 is advantageously equipped with bolts 57 (FIG. 1) in such a way that the pile driver 1 can be coupled to an existing three-point suspension of a tractor.
this piling device can also be used if the rod 25 has to be rammed into the ground at an angle. It is also conceivable to equip the pile driver 1 with a hydraulic lifting device, by means of which rods 25 or probes rammed into the ground can be pulled out of the ground. It is also conceivable to provide the pile driver 1 with a crane device, by means of which weights 23 can be brought or exchanged on the holding device of the slide.
