Description

Apparatus and method for controlling power reception between contact conductors and electric high-speed rolling stock running on rails

The invention relates to a device for controlling power reception between contact wires and electric high-speed rolling stock running on rails, comprising a streamlined housing arranged on the roof for installing a lifting mechanism, on the lifting mechanism An angled bow frame supporting the contact slide for fixing the receiver, an insulator for fixing and insulating the receiver, and a conductor for deriving the current received by the receiver.

In addition, the present invention also relates to a method for controlling power receiving between a contact wire and an electric high-speed rolling stock running on a rail, wherein a power collector having a contact slide plate and a bow frame fixed by an insulator is vertically lifted and lowered .

It is well known that the maximum speed achievable by high-speed rolling stock, especially railway rolling stock, is decisively dependent on the power reception from the contact conductors by means of current collectors, which are pressed against the contact conductors. A contact force is generated between the contact wire and the current collector, and the contact force will vary significantly due to the dynamic interaction between the contact wire and the current collector.

Factors that significantly affect the magnitude of the contact force include the friction between the contact slide and the contact conductor, the stiffness of the overhead conductor, local or temporary geometrical changes due to different heights of the contact conductor, zigzag laying of the contact conductor, contact Skateboard and contact wire wear, various aerodynamic effects due to changing driving direction and vehicle shape, wind and vehicle speed, vibration characteristics of current collectors and contact wires, and changes in flow velocity when double-track reverse driving in the tunnel, etc.

In order to adjust the contact force even at high speeds in response to significant changes in the height of the contact conductors, DE-A 3033449 describes a two-stage scissor collector, consisting of a sliding plate bow of the collector that rests on the contact conductor and is opposite to the contact conductor. An upper shear frame adjusted to a constant contact force, a main shear frame supporting the upper shear frame, a first adjustment device attached to the upper shear frame, a controller outputting an adjustment signal to the first adjustment device in order to maintain a constant contact force, and The second adjusting device that is attached to the second main shear frame. An adjustment signal is provided by means of the second controller in order to keep the adjustment travel of the first adjustment device constant over time. The main shear frame is no longer locked and its position is continuously adjusted in such a way that the adjustment stroke of the upper shear frame is kept constant on average. There is such a work distribution between the two stages of scissor power receiving, that is, the main shear frame absorbs and controls the low-frequency vibration with large amplitude, while the high-frequency vibration with small amplitude is handled by the adjustment device attached to the upper shear frame . In this case, the upper shear frame oscillates within a comparatively narrow tolerance range around an adjustment path that is constant over time.

This known scissor collector is actuated in such a way that firstly the actual value of the adjustment travel is fed as a measured variable to a second controller assigned to the main shear frame. The actuating signal of the second actuating device assigned to the main shear frame is then formed from the deviation of the actual value from the setpoint value, which corresponds to the time-average value sought by the actuating stroke of the first actuating device assigned to the upper shear frame. When the adjustment stroke changes in one direction, the upper shear frame first tracks in order to keep the contact force constant with the contact wire, and then the main shear frame is readjusted to such an extent that the original value of the adjustment stroke of the first adjustment device is reached again.

The hydraulic servomotor of this known solution complicates the structure and ultimately makes it practically impossible to implement such a two-stage scissor collector. In addition, in the case of bridging a large height difference during the driving operation, the main shear frame must be fully erected, so the small receiver supported by the upper shear frame has only a small working range, which is not enough at a speed of 7250km/h. In addition, the proposed scissor collector has the disadvantage that it can only adjust the height difference, and other factors affecting the contact force have not been considered. On the other hand, the main shear frame also has no ability to control the high-frequency contact force fluctuations that occur in the high-speed zone of 250 to 400 km/h.

Furthermore, this known two-stage scissor collector induces a high sound pressure in the high-speed region.

According to the theory of EP-A0649767, try to take measures to solve these problems, that is, fix a streamlined rigid dome shell on the roof, which installs the lower part of the receiver and the receiver is located at the lower base of two insulators (insulator and conductor) on the rotary mechanism. Conductors and insulators are staggered with each other according to the specified interval and arranged along the lateral direction of the vehicle, so as to achieve the purpose of reducing aerodynamic noise. Furthermore, insulators or conductors have streamlined cross-sections.

Although the second insulator (conductor) is located in the airflow separation zone, it contributes a modest proportion to the consistently high sound level of the entire receiver structure. Due to the comparatively rigid fixing of the insulator shaft and the conductor, this known current collector generally has unsatisfactory adjustment properties with regard to compensating contact force fluctuations and bridging large height differences.

Finally, EP-A0697304 discloses a power receiver which is capable of bridging height differences between 100 and 800 mm by means of two hydraulic lifting and lowering mechanisms arranged perpendicular to one another. The lower part of the receiver and its lifting and lowering mechanism are surrounded by an installation vault, and the lower parts of the two lifting and lowering mechanisms are combined in the skateboard bow frame body. Detect the contact force and distance between the contact slide and the contact wire, and use the measured values to adjust the vertical movement of the lifting or lowering mechanism.

When the height difference is large, the head of the receiver together with the insulator must be lifted out of the installation vault through the lifting and lowering mechanism. Therefore, the two insulators that are still staggered in the lateral direction protrude beyond the dome and cause a corresponding sound level. . Furthermore, the hydraulic lifting and lowering mechanism requires a large space, which is achieved on the one hand by the combination in the skateboard bow body and on the other hand by the large overall length of the dome mounted above the two skateboard bow bodies. The result is a complex, expensive and heavy structure.

On the basis of this prior art, the object of the present invention is to develop a current collector of the type mentioned in the introduction, which allows a smooth control of the power reception in the high-speed range by adjusting the force and/or position, while at the same time considerably reducing the aerodynamic forces. noise.

This object is achieved by a device of the type specified in the preamble having the features specified in the characterizing part of claim 1 and by a method having the features specified in the characterizing part of claim 30 . Advantageous refinements are apparent from the subclaims.

The device according to the invention makes it possible to achieve a large lifting height of the receiver and at the same time to bridge extreme height differences of the chain suspension. Aerodynamic noise is effectively reduced by having the entire lifting mechanism and insulator still surrounded by the casing even in the lifted state and by using only a single insulator. In addition, the housing on which the power receiver is mounted has a low overall height in the retracted state, so that it can be mounted on the roof of the vehicle with little maintenance and is easy.

The expensive dome mounts of the prior art can be completely eliminated. In addition, the solution according to the invention can be integrated without difficulty in the dome structure of existing vehicles.

Embodiments of the invention will be further described below with the aid of the drawings.

As shown in FIG. 1 , a streamlined shell 3 with a bottom frame 4 is installed on the roof 1 of a high-speed rolling stock 2 . The housing 3 can be part of the dome structure on the roof, but can also be mounted directly on the roof.

According to FIG. 2, the housing 3 is made up of five tubular ring segments 5 that are telescopically inserted into each other, wherein the inner segment is always supported on and guided by the outer segment. The inner cover section is also designed as an outwardly curved roof 6 and covers the outer shell 3 . A recess 7 is formed centrally in the roof 6 of the arch, and a hole 8 is provided in the center thereof. A top frame 9 is fixed on the inner top cover 6 . It has a hole 10 of the insulating frame 12 corresponding to the hole 8, through which the insulator 11 can be guided. The insulator 11 is placed on an insulating frame 12 which carries an axle nut 13 at each end symmetrically about the insulator axis B-B. In the shaft nut 13 is screwed a shaft 16 extending perpendicularly to the top frame 9 and driven by an electric motor 14 via a gear transmission 15 . The rotational motion of the motor is transmitted through the gear transmission 15 to the shaft 16, which converts the rotational motion into a vertical lifting motion and thus moves the insulating frame 12 together with the insulating body 11 through the hole 8 and into it.

The electric motor 14 , the shaft 16 , the shaft nut 13 and the gear unit 15 form a high-frequency drive 71 .

As can be seen from FIGS. 5 and 6 , each cover segment 5 has an L-shaped rib-shaped lower corner 17 pointing inwardly of the housing and an upper corner 18 likewise pointing inward. The lower corner 17 has a longer side than the upper corner 18, which serves as a stop for the associated inner cover section. In the region of the lower chamfer 17, a recess 19 is formed on the inside of the cover section 5, which extends along the inner periphery of the cover section. The cover segment 5 is made of fiber composite material, for example GFK, which is reinforced with inserts in the region of the groove 19 . The upper knuckle 18 is provided with a sealing lip 70 which seals the cavity between the inner and outer casing section 5 against the ingress of water.

A deflection device 20 consisting of a rope guide 21 and a pulley 22 is positioned in this part of the inner groove 19 . A pegboard 23 is fixed on the cover section 5 on the outside approximately above the axis of rotation of the pulley 22 . The cable guide 21 lies approximately in a vertical line aligned with the pegboard and is arranged in front of the pulley 22 when the two cover segments 5 are inserted into each other. The pulley 22 is rotatably mounted on the insert. It guarantees reliable steering of the rope.

As shown in FIG. 6, the rope 24 is suspended on the hanging plate 23 with one end thereof so as not to be lost. This rope 24 extends from the hanging plate 23 at first along a vertical line aligned with the rope guide 21, turns around through the pulley 22 and extends substantially horizontally towards a traction device 25 fixed tangentially on the periphery of the casing section. The traction device 25 comprises a tension spring 26 and a fastening element 27 which is likewise fastened to an insert.

Four such rope traction devices consisting of ropes 24, pegboards 23, rope guides 21, pulleys 22 and traction devices 25 are evenly distributed along the perimeter of the cover sections, and they respectively connect an inner cover section with an outer cover section .

The top frame 9 has at its end facing the cover section 5 a fixed connecting plate 28 for fixing the lifting mechanism 29 directed to the inside of the housing 3, and the top cover 6 is lifted or lowered by means of the lifting mechanism (see FIGS. 2 and 3). The lifting mechanism 29 consists of four scissor-type supports 30 , each of which consists of two lower support arms 31 and 32 and an upper support arm 33 . The two lower support arms 31 and 32 are provided with sliding bearings 34 . The upper support arm 33 is fixed but rotatably hinged on the fixed connecting plate 28 of the top frame 9 with its one end position, and its other end is connected with the lower support arm 31 by a hinge 35 . The other lower support arm 32 is connected via a hinge 36 to the upper support arm 33 via a lever arm 37 on which a further sliding bearing 38 is formed with the upper support arm 33 . The two hinges 35, 36 and the sliding bearings 34 and 38 thus comprise a parallelogram. In the vertical straight line of the upper support arm 33 fixed on the top frame 9 in position, there is a fixed connecting plate 39 on the bottom frame 4, and the supporting arm 31 can turn around but be fixed on this fixed connecting plate in a fixed position ( See Figure 2). This lifting mechanism is particularly suitable, for example, for large lifting heights, preferably up to 2.8 m above the roof height.

In order to compensate such as the general lifting height of the high-speed railway network, the lifting mechanism 29 is composed of at least two supports 30, which include a support arm 33 that is rotatably hinged on the top frame 9 and a rotatably hinged arm 33 that is also rotatably hinged on the bottom frame 4. The upper support arm 32. The other end of the support arm 32 is hinged to the support arm 33 .

As shown in the schematic diagram in Figure 4, the support arm 32 has a length L, the support arm 33 has a length 2L, the hinge point of the support arm 32 on the support arm 33 divides the support arm 33 into two lever arms of equal length, and, The end of the support arm 33 can move linearly on the bottom frame 4 relative to the pivot point of the support arm 32 , so the support arm 33 rises and lifts the top cover 6 .

FIG. 7 shows the electromechanical drive 40 mounted on the base frame 4 . The drive has two guide rails 41 positioned parallel to each other along the longitudinal sides of the housing segment 5 for mounting a traction chain 43 guided between two toothed rings provided with shafts 42 . The two traction chains 43 are driven by a chain drive 44 driven by an electric motor. The motion of the chain drive 44 is transmitted to the shafts 42 of the two traction chains 43 .

Both sides of the lower end of the support arm 32 are connected to the traction chain 43, supported in the guide rail 41, and thus move linearly along the guide rail 41 when the chain drive 44 moves. Because the other lower support arm 31 is fixed in place, so when the other support arm 32 lower end moves, the whole support 30 can be lifted or lowered continuously through the hinge and the sliding bearing. A chain drive 44 synchronously drives parallel traction chains 43 . So the lifting or lowering of all four carriages 30 takes place evenly. This lifting or lowering movement is transmitted to the top cover 6 . When the top cover 6 was lifted, each cover segment 5 was lifted from the inside to the outside to overcome their rope traction under the action of the spring force telescopically. When descending, the cover segment 5 is retracted from the outside to the inside by the tension of the rope under the action of the spring force. The support arms of the stand 30 are displaced inwardly when retracted. The top frame 9 of the top cover 6 is placed on the bottom frame 4 of the casing 3 when the bracket 30 is fully retracted.

The height of the cover segment 5 is approximately equal to the height of the insulator, where the head of the insulator protrudes from the hole 8 (see FIG. 5 ).

The insulator 11 is rigidly fixed on an insulating frame 12 . As shown in Figures 8 and 9, the upper insulating flange 45 supports the bow frame 46 and the streamlined skateboard bow body 47, and the contact slide plate 48 is contained in the skateboard bow body.

Between the contact slide 48 and the insulating flange 45 there is a spring damper unit 49 (see FIGS. 9 and 10 ). This spring-damper unit 49 consists of two splint-shaped one-piece levers 50 each having two mutually perpendicular and connected lever arms 51 and 52 at a distance approximately the width of the contact slide 48 . The two lever arms 51 and 52 are jointly rotatable about a fixed fulcrum Dp, wherein the lever arm 51 , which is slightly longer than the lever arm 52 , is articulated pivotably on the contact slide mount 53 with its slightly angled end. The other end of the shorter lever arm 52 is fastened on a tension spring 54 which is fixed adjustably on the insulating flange 45 . A hydraulic rotary damper 55 is fastened between two levers 50 lying parallel to one another, the actuating element 56 of which is inserted into an elongated hole 57 formed in the lever 50 . The tension spring 54 urges the lever 50 to rotate under the force acting on the contact slide 48 , so that the slightly angled lever arm 51 performs a swivel or swivel movement. This pivoting movement is continuously absorbed and damped by the rotary damper 55 . The stiffness of the tension spring 54 is very small. This spring-damper unit 49 allows only a vertical elastic action to be implemented. The rigid fixing of the skateboard bow body 47 on the insulator 11 ensures that the streamlined skateboard bow body absorbs the wind load, while the contact skateboard only shares a small aerodynamic share.

The bow 46 is provided with corners 58 ( FIG. 8 ), which can be adjusted to different bow widths, for example 1950 mm and 1600 mm, by means of a pneumatic drive 59 fitted in the skateboard bow body 47 .

As shown in the schematic diagram of FIG. 1 , the top cover 6 has a valve 60 that opens inwardly and is positioned longitudinally along the shell 3 . When the bow frame 46 turns 90° around its vertical axis and descends longitudinally along the shell 3 , the angle 58 can be inserted therein.

The high-voltage cable 61 (see Figures 11-13) laid between the insulator 11 and the connection point on the vehicle 2 not shown in the figure is helically approximated along a vertical line approximately extending the axis of the insulator around the roof Extended and secured by a tow rope 62 . At the hole 10 of the insulating frame 12, the roller mounting seat 63 ( FIG. 13 ) is connected through a flange, and the bearing seat 64 is fixed by it. An axle 65 with two sheaves 66 placed side by side is installed in the bearing block 64 . The rope 67 is guided 180° around each sheave 66, and its two rope ends lead to two deflection wheels 68 fixed on the bottom frame 4 along a vertical line, which lead these rope ends of the rope 67 to the length Very large gas tension spring 69. This rope 67 thus constitutes a traction rope 72 which is fixed under tension and which always holds the high-voltage cable 61 taut during the lifting and retracting of the hoisting mechanism 29 . The cord 67 is made of a non-conductive material such as plastic.

The pressing force acting on the contact slide 48 is a comprehensive parameter, which is due to the speed of the vehicle, the magnitude and direction of the wind force, the position of the chain suspension guiding the contact wire and its vibration induced by the current collector, friction and wind, and the relative position of the vehicle. movement, and therefore constant change. In the first active control phase of the method according to the invention, height differences of the chain suspension are compensated. The compensation takes place by means of an electromechanical drive, for example a chain drive, which compensates the height difference of the chain suspension between 4.8 and 6.3 m and the vertical vibration of the chain with an amplitude of 750 mm in the frequency range below 3 Hz. The chain drive converts the corresponding horizontal movement into a vertical movement of the lifting mechanism 29 housed in the housing 3 . At the same time, relative to this vertical movement that occurs in the first control stage, the receiver (insulator, bow frame, cable) vibrates synchronously in the second active control stage according to the frequency range to 15Hz with a maximum vertical stroke of ±50mm. The lifting movement of the second control stage is produced by high frequency actuators such as electromechanical linear drives.

In a further quasi-synchronous step, the high-frequency vibrations between the contact wire and the contact slide are absorbed and damped by removing the force between the contact slide and the current collector.
