Description

Technical Field

[0001] This invention relates to the technical field of subway equipment, specifically to an installation structure for electromechanical pipelines in subway tunnels for rapid installation. Background Technology

[0002] Generally speaking, subways are powered by either overhead cables or track power. Overhead cables, also known as contact wire power supply, are one of the two commonly used power supply network methods for electrified railways. In railway and urban rail transit systems, the overhead contact wire has only one electrode of the conductor. The train receives power through the pantograph and then returns it to the power grid through the metal wheel-rail system. The suspension types of overhead contact wires are roughly divided into three categories: simple suspension, chain suspension, and rigid suspension. Simple suspension has only conductors and no load-bearing wire. Its advantages are simple structure and low support height, and it is generally used in low-clearance situations such as tunnels. Its disadvantages are small span and the conductor oscillating up and down during operation, making it unsuitable for high-speed railways. Chain suspension connects the conductor and load-bearing wire with suspension cables and is widely used in long-distance, high-speed railways. In high-speed and long-span electrified railways, rigid suspension is a new type of suspension system that uses rigid metal strips instead of flexible conductors. Track power supply, also known as third-rail power supply, involves adding an electrified rail in addition to the two existing tracks. It is typically located between the two rails or on the outside of one of them. The train's current collector shoe contacts and slides on the electrified rail. There are three types of third-rail current collection: top contact, bottom contact, and side contact. In the top contact type, the current collector shoe presses down on the third rail head from above, collecting current from the top surface of the third rail. In the side contact type, the end face of the third rail head faces the traveling rail, and the current collector shoe collects current from the side. In the bottom contact type, the third rail head faces downwards and is mounted on a base via insulating shoulder brackets, rubber pads, buckle screws, and supports, collecting current through a carbon sliding plate.

[0003] In the third rail current collection method, the lower contact type is more widely used. When the current collector shoe and the third rail are pressed together to collect current and supply power, the tension spring pressure system provides tension to the carbon sliding plate, so that the carbon sliding plate can be pressed against the third rail, and the third rail can collect current and supply power to the carbon sliding plate. This enables the current collector shoe to dynamically draw current (i.e. collect current) from the rigid power supply rail (i.e., the third rail) for the train, thus meeting the train's power demand.

[0004] For example, the patent with announcement number CN114103649B, announcement date November 14, 2023, and titled "Current Collector Shoe and Vehicle Having Therethe", proposes a current collector shoe and a vehicle having therethe. The current collector shoe is composed of a base, a swing arm assembly, a first support member, a second support member, a carbon sliding plate assembly, a spring assembly, and a drive assembly. The base assembly and the carbon sliding plate assembly of the current collector shoe are connected by a first support member with elastic properties and a second support member with non-elastic properties. This achieves dynamic buffering contact during the contact process between the carbon sliding plate assembly of the current collector shoe and the conductive rail, and also ensures stable current collection after contact. While ensuring the stability of current collection, it greatly reduces contact impact, thereby extending the service life of the current collector shoe.

[0005] The shortcoming of the existing technology is that the carbon sliding plate is pressed against the third rail by the pneumatic lifting device and the tension spring pressure system. When the carbon sliding plate changes position due to the pneumatic lifting device and the tension spring pressure system, it swings back and forth around the swing axis of the swing arm assembly. The carbon sliding plate is located at the end of the swing arm assembly away from the swing axis, which has a stroke amplification effect. Therefore, when the carbon sliding plate bounces or due to the vibration of the vehicle, the carbon sliding plate can easily lose contact with the third rail, making it difficult to maintain stable electrical contact, thus affecting the normal power supply of the vehicle. Summary of the Invention

[0006] The purpose of this invention is to provide an installation structure for electromechanical pipelines in subway tunnels for rapid installation, thereby solving the technical problems in related technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a subway tunnel electromechanical pipeline installation structure for rapid installation, comprising a mounting frame and a swing arm unit. The mounting frame is equipped with the swing arm unit, and a carbon sliding plate is connected to the end of the swing arm unit. The structure also includes an auxiliary unit, which comprises an auxiliary frame. The end of the swing arm unit is connected to the auxiliary frame. Two hollow slots are symmetrically formed within the auxiliary frame. A positioning shaft is rotatably mounted between the two hollow slots. A carbon sliding plate is mounted on the positioning shaft. A driving component is installed in each of the two hollow slots. A positioning block is connected to the output end of each of the two driving components. Two states exist when the swing arm unit drives the carbon sliding plate to engage and disengage from the third rail:

[0008] When the carbon slide plate and the third rail are pressed together, the drive unit causes the positioning block to disengage from the positioning shaft, so that the carbon slide plate can rotate around the positioning shaft.

[0009] When the carbon slide plate disengages from the third rail, the drive unit causes the positioning block to abut against the positioning shaft, thereby positioning the carbon slide plate.

[0010] As described above, a swing shaft is rotatably mounted on the mounting bracket, a swing arm is mounted on the swing shaft, and an active component for driving the swing arm to swing is provided between the swing arm and the mounting bracket.

[0011] As described above, the swing arm consists of a force-bearing part and a swinging part, which are connected to each other to form a curved swing arm. The force-bearing part is mounted on the mounting frame via a swing shaft, and the swinging part is provided with an auxiliary frame and a carbon sliding plate.

[0012] As mentioned above, a rotatable tension spring is provided between the mounting bracket and the swing arm, so that the tension spring can adapt to the swing of the swing arm.

[0013] As mentioned above, the position of the tension spring at one end of the mounting bracket is adjustable, thereby enabling the adjustment of the tension spring force.

[0014] As described above, the carbon slide plate is eccentrically mounted in the auxiliary frame via a positioning shaft. When the positioning shaft loses the positioning of the positioning block, the carbon slide plate rotates around the positioning shaft, so that the carbon slide plate can always be in contact with the third rail.

[0015] As described above, each end of the positioning shaft is equipped with a friction wheel in the hollow groove. The two friction wheels are respectively positioned and abutted against their corresponding positioning blocks. When the carbon slide plate and the third rail are pressed together, the driving component drives the positioning block to disengage from the friction wheel, so that the carbon slide plate can rotate around the positioning shaft. When the carbon slide plate and the third rail are disengaged, the driving component drives the positioning block to abut against the friction wheel, so that the positioning block performs positioning work on the carbon slide plate.

[0016] As described above, the third rail is installed inside the insulating protective cover by a fixing component. The insulating protective cover is installed on a concrete foundation and protects the third rail.

[0017] As described above, a concave panel is provided on the positioning shaft, and a plurality of carbon sliding plates are provided inside the concave panel in the axial direction of the positioning shaft, and each carbon sliding plate is connected to the concave panel by a first spring.

[0018] As mentioned above, the mounting bracket is evenly provided with multiple bolts, which are used to stably install the mounting bracket on the chassis of the subway vehicle.

[0019] The beneficial effects of this invention are as follows: When the carbon sliding plate needs to contact the third rail to receive current, the swing arm unit drives the auxiliary frame and the carbon sliding plate to contact the third rail, so that the third rail supplies power to the subway through the carbon sliding plate. When the carbon sliding plate and the third rail contact to receive current, the driving component drives the positioning block to disengage from the positioning shaft, so that the carbon sliding plate can swing back and forth around the positioning shaft. Even if the carbon sliding plate jumps or vibrates due to the vehicle's movement, the carbon sliding plate can always contact the third rail, so that the carbon sliding plate and the third rail will not break off, thereby maintaining the stability of the carbon sliding plate and the third rail supplying power to the subway, and thus improving the stability of the vehicle's power supply.

[0041] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 18 The present invention will now be described in further detail.

[0042] One embodiment of the present invention relates to an installation structure for electromechanical pipelines in a subway tunnel for rapid installation, including a mounting frame 1 and a swing arm unit. The mounting frame 1 is equipped with the swing arm unit, and a carbon sliding plate 2 is connected to the end of the swing arm unit. An auxiliary unit is also included, comprising an auxiliary frame 3. The end of the swing arm unit is connected to the auxiliary frame 3. Two hollow slots 4 are symmetrically formed within the auxiliary frame 3. A positioning shaft 5 is rotatably mounted between the two hollow slots 4. The carbon sliding plate 2 is mounted on the positioning shaft 5. A driving component 6 is installed in each of the two hollow slots 4. A positioning block 7 is connected to the output end of each of the two driving components 6. Two states exist when the swing arm unit drives the carbon sliding plate 2 to engage and disengage from the third rail 12:

[0043] When the carbon slide plate 2 and the third rail 12 are pressed together, the driving component 6 drives the positioning block 7 to disengage from the positioning shaft 5, so that the carbon slide plate 2 can rotate around the positioning shaft 5.

[0044] When the carbon slide plate 2 and the third rail 12 disengage, the driving component 6 drives the positioning block 7 to abut against the positioning shaft 5, so that the positioning block 7 performs positioning operation on the carbon slide plate 2.

[0045] Specifically, the mounting frame 1 is the frame for mounting various components. Multiple bolts 8 are evenly distributed on the mounting frame 1, which are used to stably mount the mounting frame 1 onto the chassis of the subway vehicle. Most existing mounting frames 1 are directly welded to the subway vehicle chassis. In this embodiment, the mounting frame 1 is mounted onto the subway chassis using bolts 8, facilitating installation and making the installation of the mounting frame 1 faster and more convenient. The bottom of the mounting frame 1 has a U-shaped structure. A swing shaft 9 is rotatably mounted on the mounting frame 1, and a swing arm 10 is mounted on the swing shaft 9. An active component 11 is provided between the swing arm 10 and the mounting frame 1 to drive the swing arm 10 to swing (the active component 11 provides power for the swing arm 10 to rotate around the swing shaft 9, preferably pneumatic). The active component 11 (including cylinders and hydraulic cylinders) is rotatably mounted between the swing arm 10 and the mounting bracket 1 at both ends. This means that by setting the active component 11, the carbon sliding plate 2 and the third rail 12 can maintain appropriate contact pressure and positional relationship to adapt to different track conditions and train operating states. This is common knowledge in the field and will not be elaborated further. The third rail 12 is usually located between the two rails of the train or on the outside of one of the rails. The train's current collector contacts and slides on the energized rail, transmitting electricity to the train. An insulating protective cover 13 is installed outside the third rail 12. The third rail 12 is installed inside the insulating protective cover 13 by fixing components. The insulating protective cover 13 is installed on a concrete foundation, protecting the third rail 12. This is a safety protection device for energized tracks in subway trains. It is primarily made of insulating materials and aims to prevent accidental injury from contact with energized tracks. The insulating protective cover 13 has an auxiliary frame 3 connected to the end of the swing arm 10. Two hollow slots 4 are symmetrically formed on the inner walls of both sides of the auxiliary frame 3. A positioning shaft 5 is rotatably mounted between the two hollow slots 4. A carbon sliding plate 2 (i.e., a current collector) is installed on the portion of the positioning shaft 5 located between the hollow slots 4. The carbon sliding plate 2 can swing within the auxiliary frame 3 around the positioning shaft 5. A driving component 6 (preferably a cylinder) is installed in each of the two hollow slots 4. Each of the two driving components 6 has a positioning block 7 connected to its corresponding positioning end. The ends of the positioning shaft 5 are mutually adapted. When the carbon slide plate 2 needs to contact the third rail 12 and receive current, the active component 11 drives the swing arm 10 to swing towards the end closer to the third rail 12. The swing arm 10 drives the auxiliary frame 3 to swing towards the end closer to the third rail 12. The auxiliary frame 3 drives the carbon slide plate 2 to contact the third rail 12 through the positioning shaft 5. After the carbon slide plate 2 contacts the third rail 12, the drive component 6 is activated to cause the positioning block 7 to disengage from the positioning shaft 5, so that the carbon slide plate 2 can rotate around the positioning shaft 5. In this way, the carbon slide plate 2 can always be in contact with the third rail 12. In the prior art, when the subway is running, the carbon slide plate 2 will shake to a certain extent, causing the carbon slide plate 2 to disengage from the third rail 12, thereby affecting the carbon slide plate 2's power transmission to the subway.In this embodiment, since the carbon slide plate 2 is rotatably mounted in the auxiliary frame 3 via the positioning shaft 5, even if the subway shakes during operation, causing the swing arm 10 to shake, the carbon slide plate 2 in the auxiliary frame 3 will only rotate around the positioning shaft 5. This ensures that one end of the carbon slide plate 2 remains in contact with the third rail 12, preventing the carbon slide plate 2 from disconnecting from the third rail 12. This maintains the stability of the carbon slide plate 2 and the third rail 12 in supplying power to the subway, thereby improving the stability of the vehicle's power supply. When the train stops, before the carbon slide plate 2 needs to disengage from the third rail 12, the drive component 6 is activated to cause the positioning block 7 to abut against the positioning shaft 5. This allows the positioning block 7 to position the positioning shaft 5 and the carbon slide plate 2, preventing the swing arm 10 from moving the carbon slide plate 2. During the process of detaching the carbon sliding plate 2 from the third rail 12, it swings, causing the carbon sliding plate 2 to collide with the concrete subgrade (that is, the active component 11 drives the swing arm 10 to swing away from the third rail 12, the swing arm 10 drives the auxiliary frame 3 to swing away from the third rail 12, and the auxiliary frame 3, through the positioning shaft 5, causes the carbon sliding plate 2 to detach from the third rail 12, so that the carbon sliding plate 2 is no longer subject to current. Without positioning, the carbon sliding plate 2 is perpendicular to the auxiliary frame 3, and the swing arm 10 drives the auxiliary frame 3 to swing away from the third rail 12, which may cause the carbon sliding plate 2 to collide with the concrete subgrade, thus damaging the carbon sliding plate 2). This allows the carbon sliding plate 2 to detach from the third rail 12, enabling inspection of the carbon sliding plate 2 and providing safety assurance for the next subway operation.

[0046] The shortcoming of the existing technology is that the carbon slide plate 2 is pressed against the third rail 12 by the pneumatic lifting device and the tension spring pressure system. When the carbon slide plate 2 changes position by the pneumatic lifting device and the tension spring pressure system, it swings back and forth with the swing shaft 9 of the swing arm 10 assembly as the center. The carbon slide plate 2 is located at the end of the swing arm 10 assembly away from the swing shaft 9, which has a stroke amplification effect. Therefore, when the carbon slide plate 2 jumps or due to the vibration of the vehicle, the carbon slide plate 2 will easily lose contact with the third rail 12, making it difficult to maintain stable electrical contact, thereby affecting the normal power supply of the vehicle.

[0047] The beneficial effects of this embodiment are as follows: When the carbon slide plate 2 needs to contact the third rail 12 to receive current, the swing arm unit drives the auxiliary frame 3 and the carbon slide plate 2 to contact the third rail 12, so that the third rail 12 supplies power to the subway through the carbon slide plate 2. When the carbon slide plate 2 and the third rail 12 contact to receive current, the drive unit 6 drives the positioning block 7 to disengage from the positioning shaft 5, so that the carbon slide plate 2 can swing back and forth around the positioning shaft 5. Even if the carbon slide plate 2 jumps or vibrates due to the vehicle's movement, the carbon slide plate 2 can always contact the third rail 12, so that the carbon slide plate 2 and the third rail 12 will not disconnect, thereby maintaining the stability of the carbon slide plate 2 and the third rail 12 in supplying power to the subway, and thus improving the stability of the vehicle's power supply.

[0048] Preferably, the swing arm 10 comprises a force-bearing part and a swinging part, which are connected to form a curved swing arm 10. The force-bearing part is mounted on the mounting frame 1 via a swing shaft 9. An auxiliary frame 3 and a carbon sliding plate 2 are provided at the end of the swinging part. A rotatable tension spring 14 is provided between the mounting frame 1 and the swing arm 10, allowing the tension spring 14 to adapt to the swinging of the swing arm 10. The position of the tension spring 14 at one end of the mounting frame 1 is adjustable, thereby adjusting the tension of the tension spring 14. A sliding groove 15 is provided on the mounting frame 1. A square plate 16 is slidably installed inside. A positioning plate 17 is installed on the mounting bracket 1 at the end of the slide groove 15. A threaded rod 18 is threadedly connected to the positioning plate 17. The threaded rod 18 passes through the positioning plate 17 and is rotatably connected to the square plate 16. A swing plate 19 is rotatably installed on the square plate 16. A retaining plate 20 is provided at the connection position between the force-bearing part and the swing part on the swing arm 10. A connecting plate 21 is rotatably installed on the retaining plate 20. The connecting plate 21 and the swing plate 19 are connected by two symmetrical tension springs 14.

[0049] Specifically, during the swinging process of the swing arm 10 under the power provided by the driving member 11, the length of the tension spring 14 is stretched, and the tension spring 14 will rotate at a certain angle as the swing arm 10 swings. That is, the swing plate 19 connected to one end of the tension spring 14 rotates at a certain angle on the square plate 16, and the connecting plate 21 connected to the other end of the tension spring 14 rotates at a certain angle on the clamping plate 20. The angle rotation of the swing plate 19 and the connecting plate 21 is adapted to the angle rotation of the tension spring 14, so that the tension spring 14 can continuously provide elastic tension to the swing arm 10, so that the swing arm 10 can drive the carbon slide plate 2 to always be in contact with the third rail 12. When it is necessary to adjust the tension spring 14... When applying tension to the swing arm 10, the operator uses a tool to tighten the threaded rod 18, causing the threaded rod 18 to rotate on the positioning plate 17. The threaded rod 18 drives the square plate 16 to slide along the track of the slide groove 15, thereby adjusting the distance between the square plate 16 and the connecting plate 21, and thus adjusting the extension length of the tension spring 14. That is, the longer the distance between the square plate 16 and the connecting plate 21, the longer the extension length of the tension spring 14, and the greater the tension provided by the tension spring 14 to the swing arm 10, and vice versa. By continuously providing tension to the swing arm 10 through the tension spring 14, the swing arm 10 can apply contact pressure to the carbon slide plate 2 relatively stably, thereby ensuring that the carbon slide plate 2 can stably contact the third rail 12.

[0050] As a parallel embodiment of the above preferred embodiment, in another embodiment provided by the present invention, the square plate 16 is fixedly installed on the mounting frame 1. The mounting frame 1 has two symmetrical through slots 22 symmetrically opened in the axial direction of the tension spring 14 (that is, the stretching direction of the tension spring 14). The supporting round rod 23 is slidably installed in the two through slots 22. The square plate 16 and the supporting round rod 23 are connected by the tension spring 14. Under the tension of the tension spring 14, the supporting round rod 23 and the bottom end of the swing arm 10 are in close contact with each other.

[0051] Specifically, during the swing of the swing arm 10, the tension spring 14 needs to swing synchronously with the swing arm 10, resulting in a certain degree of bending of the tension spring 14. The tension spring 14, undergoing torsion and bending with the swing arm 10, is subjected to various stresses, which can easily lead to fatigue, deformation, or even breakage of the tension spring 14, thus affecting the contact and flow collection between the carbon slide plate 2 and the third rail 12. In this embodiment, by providing an axial groove 22 on the mounting bracket 1 for the tension spring 14, the supporting rod 23 can only slide within the groove 22. The supporting rod 23 is subjected to the tension force of the tension spring 14 at the bottom end of the swing arm 10, thus ensuring the smooth flow of the load. The supporting rod 23 provides tension to the swing arm 10. During the swing of the swing arm 10, the supporting rod 23 is always pressed against the bottom of the swing arm 10 under the tension of the tension spring 14. However, the supporting rod 23 is restricted by the through groove 22, causing the supporting rod 23 to slide in the through groove 22. This causes the pressing position between the supporting rod 23 and the swing arm 10 to change. Meanwhile, the tension spring 14 deforms along its own axial rigidity. The tension spring 14 does not follow the swing arm 10 to make adaptive swings, so it is not subjected to the torsional and bending forces generated by the swing arm 10 during the swing, thereby improving the service life of the tension spring 14.

[0052] In another embodiment of the present invention, the carbon slide plate 2 is eccentrically mounted in the auxiliary frame 3 via a positioning shaft 5. When the positioning shaft 5 loses the positioning of the positioning block 7, the carbon slide plate 2 rotates around the positioning shaft 5, so that the carbon slide plate 2 can always be in contact with the third rail 12. Each end of the positioning shaft 5 is equipped with a friction wheel 24 in the hollow groove 4. The two friction wheels 24 are respectively positioned and abutted against their corresponding positioning blocks 7. When the carbon slide plate 2 and the third rail 12 are abutted, the driving member 6 drives the positioning block 7 to disengage from the friction wheel 24, so that the carbon slide plate 2 can rotate around the positioning shaft 5. When the carbon slide plate 2 and the third rail 12 are disengaged, the driving member 6 drives the positioning block 7 to abut against the friction wheel 24, so that the positioning block 7 performs positioning operation on the carbon slide plate 2.

[0053] Specifically, since the positioning shaft 5 is installed in the middle of the carbon slide plate 2, even if the swing arm 10 swings when the subway vehicle vibrates, the positioning shaft 5 and the carbon slide plate 2 will not swing after being vibrated, thus causing the carbon slide plate 2 to separate from the third rail 12. In this embodiment, the positioning shaft 5 is set at an off-center position on the carbon slide plate 2, so that the carbon slide plate 2 and the positioning shaft 5 are the boundary. One side of the carbon slide plate 2 is longer and heavier than the other side. Preferably, the positioning shaft 5 is installed near the end of the swing arm 10, so that the carbon slide plate 2 can rotate with the positioning shaft 5 as the center line. The carbon slide plate 2 on the side away from the swing arm 10 will lift the carbon slide plate 2 on the side closer to the swing arm 10, so that the carbon slide plate 2 on the side closer to the swing arm 10 is always in contact with the third rail 12. The off-center positioning shaft 5 makes the two sides of the carbon slide plate 2 unevenly stressed, so that the carbon slide plate 2 can always be in contact with the third rail 12. The three rails 12 are in contact, which improves the stability of the contact between the third rail 12 and the carbon slide plate 2. Each end of the positioning shaft 5 is equipped with a friction wheel 24 in the hollow groove 4. The two friction wheels 24 are respectively positioned and abutted against their corresponding positioning blocks 7. When the carbon slide plate 2 and the third rail 12 are in contact, the driving component 6 drives the positioning block 7 to disengage from the friction wheel 24, so that the carbon slide plate 2 can rotate around the positioning shaft 5 as the center, so that the carbon slide plate 2 can always be in contact with the third rail 12, thereby improving the stability of the vehicle power supply. When the carbon slide plate 2 and the third rail 12 are disengaged, the driving component 6 drives the positioning block 7 to abut against the friction wheel 24, so that the positioning block 7 performs positioning operation on the carbon slide plate 2, preventing the carbon slide plate 2 from rotating around the positioning shaft 5 due to lack of positioning, which would cause the carbon slide plate 2 to collide with the concrete foundation and cause damage to the carbon slide plate 2.

[0054] In another embodiment of the present invention, a passive unit is installed on the top of the auxiliary frame 3 at each of the two hollow slots 4. The passive unit includes a plate 25. A plate 25 is installed on each side of the top of the auxiliary frame 3 at the two hollow slots 4. A driven rod 27 is rotatably mounted on the plate 25 via an auxiliary shaft 26. One end of the driven rod 27 located in the hollow slot 4 is rotatably connected to a square rod 29 via a driven shaft 28. A through groove 30 is formed on the end of the square rod 29 away from the driven shaft 28. A locking block 31 is slidably installed in the through groove 30. The locking block 31 and the inner wall of the through groove 30 are connected by a second spring 32. An abutment is rotatably mounted on the top of the plate 25 via a connecting shaft 33. Rod 34, the end of the abutting rod 34 near the hollow groove 4 is connected to the locking block 31 through the passive shaft 35. Under the elastic force of the second spring 32, the abutting rod 34 and the square rod 29 are combined to form a "V" shaped structure with the opening facing the insulating protective cover 13. A long rod 36 is slidably installed in the hollow groove 4. A brake block 37 is installed at the end of the long rod 36 near the friction wheel 24. The brake block 37 and the friction wheel 24 are mutually adapted. A transmission rod 38 is rotatably connected at the end of the long rod 36 away from the friction wheel 24. The end of the transmission rod 38 is rotatably connected to the bottom of the driven rod 27. A stop rod 39 is provided on the plate 25. The stop rod 39 and the square rod 29 are mutually adapted.

[0055] Specifically, during the reciprocating swing of the swing arm 10, which drives the auxiliary frame 3 and the carbon slide plate 2, in this embodiment, through the cooperative operation of the various abutment rods 34, driven rods 27, and insulating protective cover 13, the brake block 37 passively achieves the positioning and release of the friction force; during the movement of the swing arm 10, which drives the auxiliary frame 3 and the carbon slide plate 2 towards the third rail 12, the auxiliary frame 3 drives the plate 25 and the driven rod 27 towards the end near the insulating protective cover 13. Initially, the abutment rod, the square rod 29, and the driven rod 27 are combined to form a "V" shaped structure with the opening facing the swing arm 10 (e.g., Figure 12 , 13(As shown in Figure 16), when the swing arm 10 drives the connection position of the abutment rod 34 and the square rod 29 to rotate to a position where they abut against the outer wall of the insulating protective cover 13, the connection position of the abutment rod and the square rod 29 abuts against the outer wall of the insulating protective cover 13. Under the abutting action of the insulating protective cover 13, the abutment rod, the square rod 29, and the driven rod 27 rotate. The abutment rod 34 rotates around the connecting shaft 33. The abutment rod 34 drives the locking block 31 to rotate through the passive shaft 35. Simultaneously, the locking block 31 slides in the through groove 30, so that the locking block 31 compresses the second spring 32, causing the second spring 32 to be in a compressed state. The locking block 31 drives the square rod 29 to rotate. 9. Driven by the driven shaft 28, the driven rod 27 rotates until the square rod 29 rotates to a position where it abuts against the stop rod 39. At this point, the elastic force exerted by the second spring 32 on the locking block 31 decreases. During this process, the elastic force exerted by the second spring 32 on the locking block 31 gradually increases. When the abutting rod and the square rod 29 are connected in a straight line, the elastic force exerted by the second spring 32 on the locking block 31 reaches its maximum. When the abutting rod and the square rod 29 move to the side where the opening faces the insulating protective cover 13, the elastic force exerted by the second spring 32 on the locking block 31 gradually decreases, so that the abutting rod, the square rod 29, and the driven rod 27 combine to form a "V"-shaped structure with the opening facing the insulating protective cover 13 (e.g., ...). Figure 11 and 15 As shown), synchronously, the driven rod 27 drives the transmission rod 38 to move, the transmission rod 38 drives the long rod 36 to move away from the friction wheel 24, and the long rod 36 drives the brake block 37 to disengage from the friction wheel 24. The carbon slide plate 2 can rotate around the positioning shaft 5, so that the carbon slide plate 2 can always be in contact with the third rail 12. During the process of the swing arm 10 driving the auxiliary frame 3 and the carbon slide plate 2 to move away from the third rail 12, the auxiliary frame 3 drives the plate 25 and the driven rod 27 to move away from the insulating protective cover 13. Initially, the clamping rod, the square rod 29 and the driven rod 27 are combined to form a "V" shaped structure with the opening facing the insulating protective cover 13. At the end of the swing arm 10 driving the clamping rod and the insulating protective cover 13, the clamping rod 25 and the brake block 37 are in contact with the insulating protective cover 13. When the outer walls of the insulating protective cover 13 are pressed together, under the pressing action of the insulating protective cover 13, the pressing rod, the square rod 29, and the driven rod 27 rotate, and the abutting rod 34 rotates around the connecting shaft 33. The abutting rod 34 drives the locking block 31 to rotate through the driven shaft 35. Simultaneously, the locking block 31 slides in the through groove 30, so that the locking block 31 squeezes the second spring 32, so that the second spring 32 is in a compressed state. The locking block 31 drives the square rod 29 to rotate, and the square rod 29 drives the driven rod 27 to rotate through the driven shaft 28. The driven rod 27 drives the transmission rod 38 to move, and the transmission rod 38 drives the long rod 36 to move towards the end close to the friction wheel 24 until the long rod 36 is pressed against the inner wall of the hollow groove 4 (e.g., Figure 12 , 13As shown in Figure 16, the clamping rod, square rod 29, and driven rod 27 are combined to form a "V"-shaped structure with the opening facing the side of the swing arm 10. Simultaneously, the long rod 36 drives the brake block 37 to abut against the friction wheel 24, so that the brake block 37 performs positioning work on the friction wheel 24 and the positioning shaft 5, preventing the carbon slide plate 2 from rotating around the positioning shaft 5 because it is not positioned, which would cause the carbon slide plate 2 to collide with the concrete foundation and thus damage the carbon slide plate 2.

[0056] In another embodiment of the present invention, a friction rod 40 is rotatably mounted on the top of the brake block 37, and a sliding round rod 41 is mounted on the end of the friction rod 40. Two limiting grooves 42 are symmetrically opened on the inner wall of the hollow groove 4. The sliding round rod 41 is slidably mounted in the limiting groove 42. The end of the limiting groove 42 near the brake block 37 is an inclined groove 43, which slopes downward from the end near the brake block 37 to the end away from the brake block 37. The end of the limiting groove 42 away from the brake block 37 is a straight groove 44 parallel to the long rod 36. The straight groove 44 and the inclined groove 43 are connected to each other to form the limiting groove 42. The friction rod 40 and the friction wheel 24 are rubbed and adapted to each other.

[0057] Specifically, due to the eccentric arrangement between the positioning shaft 5 and the carbon slide plate 2, during the process of the swing arm 10 driving the carbon slide plate 2 and the third rail 12 to disengage from the brake block 37 to position the friction wheel 24, the carbon slide plate 2 will still rotate around the positioning shaft 5. This causes the carbon slide plate 2 to be in an inclined state within the auxiliary frame 3 when the brake block 37 positions the friction wheel 24. After the swing arm 10 drives the carbon slide plate 2 to disengage from the third rail 12, the carbon slide plate 2 may collide with the concrete foundation, causing damage to the carbon slide plate 2 after the collision. In this embodiment, during the swing arm... As the auxiliary frame 3 and carbon slide plate 2 move closer to the third rail 12, the auxiliary frame 3 moves the plate 25 and driven rod 27 closer to the end of the insulating protective cover 13. Initially, the clamping rod, square rod 29, and driven rod 27 are combined to form a "V"-shaped structure with the opening facing the side of the swing arm 10. When the swing arm 10 drives the connection position of the clamping rod 34 and square rod 29 to a position where they are pressed against the outer wall of the insulating protective cover 13, the connection position of the clamping rod and square rod 29 is pressed against the outer wall of the insulating protective cover 13. Under the pressure of rod 3, the clamping rod, square rod 29, and driven rod 27 rotate, and the abutting rod 34 rotates around the connecting shaft 33. The abutting rod 34 drives the locking block 31 to rotate through the driven shaft 35, so that the clamping rod, square rod 29, and driven rod 27 combine to form a "V"-shaped structure with the opening facing the insulating protective cover 13. The driven rod 27 drives the transmission rod 38 to move, and the transmission rod 38 drives the long rod 36 to move away from the friction wheel 24. The long rod 36 drives the brake block 37 to disengage from the friction wheel 24. Simultaneously, the long rod 36 and the brake block... 37 drives the friction rod 40 to move away from the friction wheel 24. The friction rod 40 drives the sliding round rod 41 to slide from the straight groove 44 to the inclined groove 43. When the friction rod 40 drives the sliding round rod 41 to the connection position of the inclined groove 43 and the straight groove 44, the carbon slide plate 2 near the swing arm 10 contacts the third rail 12. The sliding round rod 41 continues to slide along the trajectory of the inclined groove 43. Under the pressing action of the third rail 12, the carbon slide plate 2 continues until the sliding round rod 41 slides to the end of the stroke of the inclined groove 43. The friction rod 40 tilts at the end of the inclined groove 43 (e.g., Figure 15 As shown), the brake block 37 and the friction wheel 24 disengage from each other, the brake block 37 releases its positioning operation on the friction wheel 24, and the carbon slide plate 2 is pressed by the third rail 12. The carbon slide plate 2 rotates around the positioning shaft 5, so that the carbon slide plate 2 and the third rail 12 are parallel to each other.

[0058] As the swing arm 10 drives the auxiliary frame 3 and the carbon slide plate 2 to move away from the third rail 12, the auxiliary frame 3 drives the plate 25 and the driven rod 27 to move away from the insulating protective cover 13. Initially, the clamping rod, the square rod 29, and the driven rod 27 are combined to form a "V"-shaped structure with the opening facing the insulating protective cover 13. When the end of the clamping rod driven by the swing arm 10 abuts against the outer wall of the insulating protective cover 13, under the clamping action of the insulating protective cover 13, the clamping rod, the square rod 29, and the driven rod 27 rotate, and the abutting rod 34 rotates around the connecting shaft 33. The abutting rod 34 is passively... Shaft 35 drives the locking block 31 to rotate, the locking block 31 drives the square rod 29 to rotate, the square rod 29 drives the driven rod 27 to rotate via the driven shaft 28, the driven rod 27 drives the transmission rod 38 to move, and the transmission rod 38 drives the long rod 36 to move towards the end closer to the friction wheel 24 until the long rod 36 abuts against the inner wall of the hollow groove 4, so that the abutting rod, the square rod 29 and the driven rod 27 combine to form a "V" shaped structure with the opening facing the swing arm 10. Simultaneously, the long rod 36 drives the brake block 37 to move towards the end closer to the friction wheel 24, and the brake block 37 drives the friction rod 40 to move towards the end closer to the friction wheel 24. The friction rod 40 drives the sliding round rod 41 to slide from the inclined groove 43 into the straight groove 44. The friction rod 40 is limited by the straight groove 44, ensuring that it is parallel to the long rod 36 under the limiting action of the sliding round rod 41 and the brake block 37. This causes the friction rod 40 and the friction wheel 24 to rub against each other. As the sliding round rod 41 and the friction rod 40 move towards the end of the swing arm 10, the friction rod 40 provides a certain rotational force to the friction wheel 24 through friction with it. The frictional force from the friction rod 40 on the friction wheel 24 balances the eccentricity. The positioning shaft 5 and the tilting force of the carbon slide plate 2 (that is, the carbon slide plate 2 and the positioning shaft 5 are eccentrically set, and the carbon slide plate 2 has a tilting rotation force during the process of disengaging from the third rail 12) make the friction force generated by the friction rod 40 on the friction wheel 24 balance with the tilting force of the carbon slide plate 2, so that the carbon slide plate 2 will not rotate around the positioning shaft 5 in the auxiliary frame 3, and the carbon slide plate 2 can always be set parallel to the auxiliary frame 3, so that the carbon slide plate 2 will not collide with the concrete foundation, thereby improving the stability of the swing arm 10 driving the carbon slide plate 2 to swing.

[0059] To ensure the stability of the contact between the carbon slide plate 2 and the third rail 12, preferably, a concave panel 45 is provided on the positioning shaft 5, and a plurality of carbon slide plates 2 are provided in the concave panel 45 along the axial direction of the positioning shaft 5, and each carbon slide plate 2 is connected to the concave panel 45 by a first spring 46.

[0060] Specifically, when the auxiliary frame 3 drives the carbon slide plate 2 to contact the third rail 12 via the positioning shaft 5, the positioning shaft 5 drives the concave panel 45 to move towards the end closer to the third rail 12. This causes the concave panel 45 to drive the carbon slide plate 2 to contact the third rail 12 via the first spring 46. Under the pressure of the third rail 12, the carbon slide plate 2 performs a certain pressure operation on the first spring 46, making the pressure contact between the carbon slide plate 2 and the third rail 12 more stable. By having multiple carbon slide plates 2 evenly arranged to contact the third rail 12, when one carbon slide plate 2 is damaged, the other carbon slide plates 2 can still contact the third rail 12 and receive current. This can greatly reduce the impact of carbon slide plate 2 damage on the subway power supply and improve the stability of the carbon slide plate 2 for the subway power supply.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
