Description

DEVICE AND METHOD FOR CONTROLLED CURRENT COLLECTION BETWEEN A CONTACT WIRE AND A TRACK-BOUND, ELECTRICALLY OPERATED HIGH SPEED VEHICLE}

The maximum speed which can be achieved by a high speed vehicle, in particular a railway vehicle, is determined by means of current collectors, as known, by means of current collectors, which are pressurized against the contact wires. A contact force is generated between the contact wire and the current collector, and the contact force can be changed by the dynamic interaction of the contact wire and the current collector.

The magnitude of the contact force may vary depending on the height of the different contact wires, the zigzag-movement of the contact wires, the wear of the wear strips and contact wires, the different aerodynamic effects depending on the direction of movement and the type of vehicle being replaced, wind and vehicle speed, current collector and The vibration characteristics of the contact wires, and local or temporary structural changes due to changes in flow velocity during reverse operation in the tunnel, are significantly affected by the strength of the contact lines, the friction between the wear strips and the contact wires.

DE-A 30 33 449 discloses an upper sheer provided with a contact wire through a current collector locker at a high speed to adjust the contact force in response to a certain change in the contact wire, while being adjusted to a constant contact force along the contact wire. shear), a main sheath supporting the upper sheer, a first regulating device assigned to the upper sheer, a regulating device sending a control signal to the upper sheath to maintain a constant contact force, and a first assigned to the second main sheath. Two-stage pantograph current collectors are known which comprise two regulating devices. An adjustment signal is provided by the second adjustment device to keep it constant when averaging the adjustment distance of the first adjustment device. The main sheer is no longer adjusted and its position is adjusted so that the adjustment distance of the upper sheer remains constant on average. The division of work between the two stages of the pantograph current collector is such that low frequency vibrations are received and regulated by the main shear with a relatively large width, and high frequency vibrations are processed by a control device assigned to the upper shear with a relatively small width. In this case, the upper sheer, which is within a relatively narrow threshold range, oscillates around the adjustment distance consistently when averaged over time.

As the adjustment of the known pantograph current collector is performed, the actual value of the adjustment distance is first provided as a measurement variable to the second adjustment device assigned to the main shear. The control signal for the second regulating device assigned to the main sheath consists of a deviation of the actual value from the set value, which corresponds to the temporal average to be pursued of the adjusting distance of the first regulating device assigned to the upper shea. . When the adjustment distance is changed in one direction, first, for the safety of the contact force on the contact line, the upper sheer is reguided and then the main sheer is readjusted to reach the original value of the adjustment distance of the first adjusting device.

The hydraulic servo motor according to the known theory complicates the structure, which in turn makes the two-stage pantograph current collector impossible to be practically implemented. In addition, when adjusting the high altitude difference during operation, the main shear is completely installed, so that the small current collector supported by the main shear has a very small operating area. The small current collector is not suitable when the speed is higher than 250 km / h. The pantograph current collector also has the disadvantage that only the altitude difference can be adjusted by the apparatus and that other influence variables on the contact force remain unconsidered. On the other hand, the main shear can be adjusted if the high frequency contact force as seen in the high speed range between 250 and 400 km / h does not vary.

The known two-stage pantograph current collector also causes significant sound pressure in the high speed range.

The problems are solved in the theory according to EP-A 0 649 767 by fixing a streamlined help housing on the vehicle roof, which helps the bottom part of the current collector to the bottom of two insulators (insulator and line). Receive with a swinging device placed on the foot. The lines and the insulators are displaced from each other in the transverse direction of the vehicle at predetermined intervals, thereby reducing aerodynamic noise. The insulator and line also have a streamlined cross section.

Although the second insulator (line) is arranged in the separation edge region of the air flow, the large size of the second insulator is still involved in the still high noise level of the entire current collector. Due to the relatively fixed fixation of the insulator and the line, the known current collector has equalized contact force fluctuations and has an overall unsatisfactory adjustment characteristic when adjusting a large altitude difference.

Finally, EP-A 0 697 304 discloses a current collector in which an elevation difference between 100 and 800 mm is adjusted by two vertically overlapping hydraulic lifting- and lowering devices. The lower parts of the current collecting device, including the lifting and lowering devices, are enclosed by the receiving aid, and the lower parts of both lifting and lowering devices are integrated into the vehicle body. The contact force or spacing between the wear strip and the contact wire is measured, and the measured values control the vertical movement of the lifting and lowering device.

If the altitude difference is large, the head of the current collector, including the insulator, must be correspondingly pulled out of the receiving aid by the lifting-and-lowering device, so that both insulators which are laterally displaced and protrude through the help, Cause a noise level. The hydraulic lifting- and lowering device also has a space, on the one hand, which is integrated into the vehicle body, on the other hand by the fact that the structure of the receiving aid on the two vehicle bodies is formed to be quite long. This results in complex, expensive and heavy structures.

The present invention is provided by an insulator and current collector for securing and insulating the current-carrying device and a streamlined housing disposed in the vehicle roof for supporting a lifting device to which the rocker of the current collector is fixed, which supports a wear strip and comprises a horn. An apparatus for regulating current collection between an electrically operated high speed vehicle connected to a track and a contact wire, comprising a line for discharging the received current.

The invention also relates to a method for regulating current collection between electrically operated high speed vehicles and contact wires connected to a track, comprising a wear strip and a rocker, wherein the current collector secured by the insulator is raised or lowered vertically. .

It is an object of the present invention to develop a current collector in the manner mentioned at the outset, which makes it possible without problem to allow a current to be controlled in the high speed range by means of power- and / or bearing adjustment, and at the same time significantly reduce aerodynamic noise.

This object is achieved by an apparatus in the manner mentioned at the beginning with the features of claim 1 and by a method with the features of claim 30.

Preferred embodiments may be presented in the dependent claims.

The device according to the invention allows a large height current collector to come out and at the same time adjust the extreme altitude difference of the chain device. Even when the entire lifting device and the insulator are pulled out, they are kept surrounded by the housing, and by using only one insulator, the aerodynamic noise is effectively reduced. The housing that houses the current collector has a low height when inserted and can be simply mounted on the roof of the vehicle without the need for retrofitting.

Complex help receptacles implemented in the prior art can be omitted entirely. On the other hand, according to the solution according to the invention it is possible to seamlessly integrate the help receptacle into the help structure of the existing vehicle.

The invention is explained in more detail in the following examples with reference to the drawings.

As shown in FIG. 1, the streamlined housing 3 including the base frame 4 is mounted on the roof 1 of the high speed vehicle 2. The housing 3 can be part of a help structure on the vehicle roof and can also be mounted directly on the roof.

According to FIG. 2 the housing 3 consists of five telescopic shaped pipe-shaped pivoting cover segments 5 which are superimposed into one another, of which the cover segments located inside are supported and guided to the outer cover segments. do. The inner cover segment is formed as an arcuate cover loop 6 facing outwards at the same time and covers the housing 3. A recess 7 is formed in the middle of the arcuate cover loop 6, and an opening 8 is provided in the middle thereof. A loop frame 9 comprising an opening 10 of the insulator support 12 corresponding to the opening 8 is fixed to the inner cover loop 6, through which the insulator 11 can be guided. have. The insulator 11 is located on the insulator support 12 that supports the spindle nut 13 on the end side, symmetrically with respect to the insulation axis B-B. A spindle 16 extending perpendicular to the loop frame 9 and driven by the toothed gear device 15 by the electric motor 14 is inserted into the spindle nut 13. The rotational movement of the motor is transmitted to the spindle 16 via the toothed gear device 15, which converts the rotational movement into a vertical lifting movement, thus opening the insulator support 12 including the insulator 11. Eject or insert through 8).

The electric motor 14, the spindle 16, the spindle nut 13 and the toothed gear device 15 form a high frequency drive 71.

As shown in FIGS. 5 and 6, each cover segment 5 comprises an L-shaped stopper-shaped lower bend 17 facing into the housing and likewise an upper bend 18 facing inward. The lower bend 17 has an approximately longer arm than the upper bend 18, which arm is used as a stopper for each inner cover segment. In the region of the lower bend 17 a groove 19 is formed on the inner side of the cover segment 5, which extends along the inner circumference of the cover segment. The cover segment 5 is made of a fiber composite material, such as GFK, which is reinforced in the region of the groove 19 including the insert. The upper bend 18 is provided with a sealing lip 70 which seals the space between the inner and outer cover segments 5 against humidity.

The redirection device 20 consisting of the cable guide 21 and the roller 22 is located in this part of the groove 19 on the inner side.

On the outer side, the inset plate 23 is fixed to the cover segment 5 at approximately the top of the axis of rotation of the roller 22. When the two cover segments 5 overlap each other, the cable guide 21 is located in a straight line approximately perpendicular to the inset plate and arranged in front of the roller 22. The roller 22 is pivotally supported at the insert. This ensures reliable cable redirection.

As shown in FIG. 6, one end of the cable 24 is hooked to the inset plate 23 so as not to be lost. The cable 24 first extends in a straight line perpendicular to the cable guide 21 from the inset plate 23 and is directed through the roller 22 to the tensioning device 25 which is fixed in contact with the circumference of the outer cover segment. Is switched. The tensioning device 25 comprises a tension spring 26 and likewise a fixing part 27 fixed to the insert.

The four cable pools consisting of the cable 4, the inset plate 23, the cable guide 21, the roller 22 and the tensioning device 25 of the above manner are evenly distributed around the cover segment, one inside The cover segments are each connected with one outer cover segment.

The roof frame 9 has a fixing shackle 29 for fixing the lifting device 29, from the end assigned to the cover segment 5, towards the interior of the housing 3, by means of the fixing shackle a cover loop ( 6) is raised or lowered (see FIGS. 2 and 3). The lifting device 29 consists of four sheer support structures 30, one of which consists of two lower support arms 31 and 32 and an upper support arm 33, respectively. Two lower support arms 31 and 32 are provided with moving bearings 34. The first end of the upper support arm 33 is pivotally fixedly linked to the fixed shackle 28 of the loop frame 9, the second end of which is connected to the lower support arm 31 via the joint 35. do. The other lower support arm 32 is connected by an upper support arm 33 and a lever arm 37 via a joint 36, which lever arm forms an additional moving bearing 38 in the upper support arm 33. do. The two joints 35 and 36 and the moving bearings 34 and 38 form a parallelogram. A fixed shackle 39 is present in the base frame 4 in a vertical straight line of the upper support arm 33 fixed to the loop frame 9, where the support arm 31 is pivotable but is also fixed (FIG. 2). The lifting device is for example particularly suitable for very high heights, especially for heights up to 2.8 m above the vehicle roof height.

For example, in order to compensate for the normal lifting height of the high speed rail net, the lifting device 29 consists of at least two support structures 30, which support arms 33 are pivotally linked to the roof frame 9. And likewise a support arm 32 pivotally linked to the base frame 4. The other end of the support arm 32 is connected to be linked to the support arm 33, and as shown in principle in FIG. 4, the support arm 32 has a length L and the support arm 33 has a length ( 2L). The connection point of the support arm 32 on the support arm 33 divides the support arm 33 into two equal length lever arms, and the end of the support arm 33 is supported on the base frame 4. By being able to move linearly with respect to the pivot point of the arm 32, the support arm 33 is upright and the cover loop 6 is lifted.

7 shows an electrical engineering drive 40 mounted on the base frame 4. The drive device comprises two guide rails 41 lying parallel to each other, located along the longitudinal side of the cover segment 5, for receiving a chain pool 43 guided between two gear rims provided with a shaft 42. It includes.

The two chain pools 43 are driven by a chain drive 44 which is operated by an electric motor. Operation of the chain drive 44 is transmitted to the shaft 42 of the two chain pools 43.

The lower end of the support arm 32 is connected to the chain pool 43 on both sides and supported on the guide rail 41, thus moving linearly along the guide rail 41 when the chain drive 44 is operated. do. Since the other lower support arm 31 is fixed, the entire support structure 30 can continue to be lifted or lowered through the joint and the moving bearing when the lower end of the other support arm 32 is moved. By the chain drive 44 driving the parallel chain pool 43, the lifting and lowering of all four support structures 30 is made even. This lifting or lowering movement is transferred to the cover loop 6. Upon lifting of the cover loop the individual cover segments 5 are telescoped out from the inside to the cable pools provided with elastic force. On lowering, the cover segment 5 is inserted from the outside into the inside by a cable pool provided with elastic force. Upon insertion, the support arms of the support structure 30 are repositioned inwards. The roof frame 9 of the cover loop 6 is provided on the base frame 4 of the housing 4 when the support structure 30 is fully inserted.

The height of the cover segment 5 corresponds approximately to the height of the insulator, and the insulator head protrudes from the opening 8 (see FIG. 5).

The insulator 11 is fixed to the insulator support 12. As shown in FIGS. 8 and 9, the upper insulator edge 45 supports the rocker 46, including the streamlined rocker body 47, on which a wear strip 48 is supported.

There is a spring damper unit 49 between the wear strip 48 and the insulator flange 45 (see FIGS. 9 and 10). The spring damper unit 49 consists of two integral levers 50 comprising two mutually positioned lever arms 51 and 52 which are each perpendicular to each other, of bracket type, approximately spaced apart by a wear strip 48 width. . The two lever arms 51 and 52 can pivot together around a fixed point of rotation D _P , with the slightly curved end of the lever arm 51 slightly longer than the lever arm 52. It is linked so that it can turn to 53. The short lever arm 52 is fixed to the tension spring 54 on the other side, and the tension spring is settable to be fixed to the insulator flange 45. A hydraulically actuated rotary damper 55 is fixed between two levers 50 parallel to each other, the actuating member 56 of which is inserted into a long hole 57 integrated in the lever 50. The tension spring 54 causes the pivoting motion of the lever 50 when a force acts on the wear strip 48 such that the slightly curved lever arm 51 performs the pivoting- or rotational motion. This turning movement is prevented or damped by the rotary damper 55 for a long time continuously. Tension spring 54 has a very small strength. This spring damper unit 49 enables only vertical turning. As the rocker body 47 is fixed to the insulator 11, wind loads are received by the streamlined rocker body, and only very small aerodynamic loads are given to the wear strips.

The rocker 46 is provided with a horn 58 (FIG. 8), which can be set to different rocker widths, for example 1950 mm and 1600 mm, by a pneumatic drive 59 mounted to the rocker body 47. Can be.

As shown in principle in FIG. 1, the flap valve 60 located in the longitudinal direction of the housing 3, which is open inwardly, is located in the cover loop 6, and the rocker 46 is the length of the housing 3. If it rotates around its vertical axis by 90 ° in the direction and descends, a horn 58 can be inserted into the valve.

The displaced high voltage cable 61 (see FIGS. 11-13) between the insulator 11 and the connection point of the vehicle 2, not shown (see FIGS. 11-13), spirally around the insulator axis extending in a vertical straight line onto the roof of the vehicle. It is extended and fixed by the cable pool 62. The roller receiving portion 63 (FIG. 13) is flanged to the opening 10 of the insulator support 12, and the bearing block 64 is fixed by the roller receiving portion. The bearing block 64 houses a shaft 65 comprising two cable rollers 66 located side by side. One cable 67 is guided by less than 180 degrees around each cable roller 66 and its two cable ends are fixed to the base frame 4 in a vertical straight line. Guided by the gas tension spring 69 with a very long length. The cable 67 forms a cable pool 72 which is fixed by a tension force, which tensions and fixes the high voltage cable 61 at all times when the lifting device 29 is pulled out or inserted.

The cable 67 is made of a non-conductive material, such as plastic.

The compressive force acting on the wear strip 48 is a complex value. The value of the compressive force is continually changed by the vehicle speed, wind strength and wind direction, the position of the chain device guided by the contact wires and the vibrations caused by its current collection, friction and wind and the relative movement of the vehicle. The altitude difference of the chain device is compensated for in the first active adjustment step of the method according to the invention. The compensation is made by an electrical engineering drive, such as a chain drive, which drives the vertical chain vibration with an amplitude greater than 50 mm and the altitude difference of the chain device between 4.8 and 6.3 m in the frequency range below 3 Hz. To compensate. The chain drive converts the corresponding horizontal movement into the vertical movement of the lifting device 29 encapsulated in the housing 3. In connection with the vertical movement occurring in the first adjustment stage, the current collector (insulator, rocker, cable) oscillates simultaneously with a vertical lifting of up to ± 50 mm in the frequency range up to 15 Hz in the second active adjustment stage. The lifting movement of the second adjusting step is generated by a high frequency actuator, for example an electric motorized linear drive.

The high frequency vibrations between the contact wires and the wear strips are received and attenuated by the breakup of forces between the wear strips and the current collector in an additional step that occurs almost simultaneously.
