[0017] The clamping member is rotatably connected to the second guide member, and the rotation axis of the clamping member extends along the second direction.

[0018] In one embodiment, one of the first guide member and the second guide member is a guide rod, and the other has a guide channel, wherein the guide rod is slidably inserted in the guide channel along the extension and retraction direction of the telescopic part.

Detailed Implementation

[0034] One embodiment of this application provides a track linkage clamping device, which is installed on the body of a rail vehicle for use with the track.

[0035] Another embodiment of this application provides a rail transit vehicle, including a vehicle body and a track linkage clamping device as described in any embodiment of this application, wherein the track linkage clamping device is disposed on the vehicle body.

[0036] It should be noted that the rail transit vehicles in this application refer to vehicles that need to run on specific tracks, including transport vehicles such as Skybuses, light rail, and subways, as well as track maintenance vehicles used for the maintenance of tracks and track-related facilities. For ease of description, this application specification uses a track maintenance vehicle as an example of a rail transit vehicle.

[0037] Please see Figures 1 to 3 The track linkage clamping device includes a telescopic assembly 10 and a clamping assembly 20. The telescopic assembly 10 includes a fixed part 11 and a telescopic part 12, with the telescopic part 12 being telescopically mounted on the fixed part 11. The clamping assembly 20 includes a clamping part 21 and a driving part 22. The clamping part 21 is mounted on the telescopic part 12, and the driving part 22 is drivenly connected to the clamping part 21 to clamp or disengage from the track.

[0038] Specifically, the telescopic component 10 is used to drive the clamping component 20 to move relative to the vehicle body. The fixing part 11 is used to connect to the vehicle body so that the track-linked clamping device can be securely connected to the vehicle body. The telescopic part 12 moves relative to the fixing part 11, thereby driving the clamping component 20 to move relative to the vehicle body.

[0039] It is understandable that the telescopic part 12 drives the clamping component 20 to move in order to adjust the positional relationship between the clamping component 20 and the track, so that the clamping part 21 can accurately clamp the track.

[0040] In fact, the telescopic part 12 will only drive the clamping part 21 to clamp the track after it has been extended to the set position, or it will disengage from the track after clamping the track.

[0041] For example, the telescopic part 12 extends to move towards the side closer to the track to a set position, and the drive part 22 drives the clamping part 21 to clamp the track. After maintenance is completed, the drive part 22 drives the clamping part 21 to disengage from the track. The telescopic part 12 retracts to move away from the track to the initial position.

[0042] The specific structure of the telescopic component 10 is not limited; for example, the telescopic component can be a telescopic hydraulic cylinder.

[0043] The specific structure of the drive unit 22 is not limited; for example, the drive unit 22 can be a clamping cylinder.

[0044] The track linkage clamping device of this application embodiment includes a telescopic component 10 and a clamping component 20. The clamping component 20 includes a clamping part 21 and a driving part 22. The clamping part 21 is disposed on the telescopic component 12, and the driving part 22 is drivenly connected to the clamping part 21 so that the clamping part 21 clamps or disengages from the track. Therefore, when the rail transit vehicle is in a parked state, the clamping part 21 clamps the track, which can improve the parking stability of the rail transit vehicle and prevent the rail transit vehicle from derailing, thereby reducing the safety risks during parking. Furthermore, the telescopic component 12 extends and retracts, driving the clamping component 20 to move. This allows the clamping part 21 to accurately clamp onto the track during the parking process, and also allows the clamping component 20 to retract during the operation of the rail transit vehicle to prevent the clamping component 20 from interfering with the operation of the rail transit vehicle. Thus, through the linkage between the clamping part 21 and the telescopic component 12, the stability and accuracy of clamping the track can be ensured.

[0045] In one embodiment, please refer to Figure 4 and Figure 5 The clamping part 21 includes two hooks 211. The driving part 22 drives the two hooks 211 to move closer to each other to clamp the track, or to move further apart to disengage from the track. Thus, the track linkage clamping device can improve the parking stability of rail transit vehicles while avoiding an overly complex structure, making it easier to manufacture and operate by maintenance personnel.

[0046] Specifically, driven by the drive unit 22, the two hooks 211 cooperate with each other to clamp the track by moving towards each other and to disengage from the track by moving away from each other.

[0047] Understandably, during the process of the two hooks 211 clamping the track, the clamping assembly 20 has already moved to the set position under the drive of the telescopic part 12.

[0048] It should be noted that the two hooks 211 can cooperate to clamp or disengage from the track, and their specific shape is not limited. When clamping the track, their positions and shapes can be completely symmetrical. Of course, they can also be symmetrical only in position, but differ in shape.

[0049] Furthermore, the material of the hook 211 is not limited. For example, it can be a material with lower strength than the rail material. This is because when the material of the hook 211 is set to have lower strength than the rail material, damage to the rail due to the clamping of the hook 211 can be avoided. In some special cases, such as large impacts or shearing, only the hook 211 with lower material strength will be damaged, and the rail will not be damaged.

[0050] In one specific embodiment, the hook 211 is made of copper or soft iron. Since the track is generally made of a high-strength material, such as high-grade steel, copper or soft iron can be used to clamp the track.

[0051] In one specific embodiment, the clamping part 21 includes two clamping bodies and two hooks 211 corresponding to each clamping body. The hooks 211 are detachably disposed at one end of the clamping body. This facilitates the repair and replacement of the hooks 211 if they are damaged.

[0052] In one embodiment, please refer to Figure 2 The telescopic assembly 10 also includes a clamping member 13 disposed on the telescopic part 12, the clamping member 13 being used to abut against the track.

[0053] Specifically, the clamping member 13 serves to position the rail and improve the stability of the track-linked clamping device. When the telescopic part 12 extends to a set position towards the side closest to the rail, after the clamping member 13 abuts against the rail, the drive part 22 drives the clamping part 21 to clamp the rail. The clamping member 13 can fit against the rail and apply a certain pressure to it, which can further improve the stability of the rail vehicle in the parked state, thereby improving safety performance.

[0054] It should be noted that the clamping member 13 can also serve as a support. When the telescopic part 12 extends towards the side closer to the track so that the clamping member 13 abuts against the track, the telescopic assembly 10 can act as a support leg for the rail transit vehicle to stably support the main body of the rail transit vehicle. This can further improve the stability of the rail transit vehicle in the parked state.

[0055] Furthermore, with the clamping member 13 abutting against the rail to support the vehicle body, the clamping part 21 clamping the rail further strengthens the fixing effect of the rail linkage clamping device on the vehicle body. For example, when the vehicle body of the rail transit vehicle is tilted, on the one hand, the telescopic component 10 can stably support the vehicle body by the clamping member 13 abutting against the rail. On the other hand, the clamping part 21 clamping the rail can also hold the vehicle body in place, thus stabilizing and supporting the vehicle body.

[0056] In addition, the clamping member 13 and the telescopic part 12 can be rigidly connected, or they can be connected in a way that can generate relative displacement.

[0057] For example, please refer to Figure 2 The clamping member 13 is rotatable relative to the telescopic part 12, and the axis of rotation of the clamping member 13 can extend along a first direction or a second direction. When the clamping part 21 is installed on the vehicle body, both the first and second directions are parallel to the horizontal plane, and the first and second directions intersect.

[0058] Specifically, the clamping member 13 can rotate relative to the telescopic part 12 with its axis of rotation extending along the first direction as the axis of rotation. Alternatively, it can rotate relative to the telescopic part 12 with its axis of rotation extending along the second direction as the axis of rotation. Furthermore, when the clamping part 21 is installed on the vehicle body, both the first and second directions are parallel to the horizontal plane, but they are intersecting, meaning they are not parallel. This allows the clamping member 13 to be adjusted in different directions, enabling fine adjustments to the angle of contact with the rail. This facilitates smoother force transmission between the telescopic part 12, the clamping member 13, and the rail, preventing damage to the rail linkage clamping device. Simultaneously, it allows the clamping member 13 to better clamp the rail, improving the stability of the rail vehicle in the parked state.

[0059] It should be noted that the intersection angle between the second direction and the first direction can be any angle other than zero. Preferably, the intersection angle between the second direction and the first direction is 90°, which facilitates the angle adjustment of the clamping member 13.

[0060] In some embodiments, the rotation axis of the clamping member 13 may extend only along the first direction, or the rotation axis of the clamping member 13 may extend only along the second direction.

[0061] It should be noted that the clamping component 13 can be rotatably connected to the telescopic part 12 via a bearing, such as a universal joint bearing or a rolling bearing.

[0062] In one embodiment, please refer to Figure 2 The telescopic assembly 10 also includes a first guide member 14 and a second guide member 15. The first guide member 14 is disposed on the fixed part 11, and the second guide member 15 is disposed on the telescopic part 12. During the telescopic process of the telescopic part 12, the second guide member 15 cooperates with the first guide member 14 to guide the telescopic movement of the telescopic part 12. This improves the stability of the telescopic part 12 during the telescopic process of driving the clamping assembly 20 to extend and retract.

[0063] Specifically, the first guide member 14 and the second guide member 15 cooperate to guide the telescopic part 12 to extend and retract relative to the fixed part 11.

[0064] The specific structure of the first guide member 14 and the second guide member 15 is not limited.

[0065] For example, please see Figure 2 One of the first guide member and the second guide member 15 is a guide rod, and the other has a guide channel. The guide rod is slidably inserted in the guide channel along the telescopic direction of the telescopic part 12.

[0066] Specifically, the first guide member 14 can be a guide rod, and the second guide member 15 can be a guide member with a guide channel. By inserting the guide rod through the guide channel, the guide rod can also slide along the guide channel during the extension and retraction of the telescopic part 12, thereby enabling the first guide member 14 and the second guide member 15 to cooperate and guide each other.

[0067] Of course, the first guide member 14 can also be a guide member with a guide channel, and the second guide member 15 can be a guide rod.

[0068] For example, one of the first guide member 14 and the second guide member 15 is a slide rail, and the other has a slide groove, which guides the guide member by sliding along the slide groove.

[0069] In one embodiment, the clamping member 13 is rotatably connected to the telescopic part 12, and the rotation axis of the clamping member 13 extends along a first direction. The clamping member 13 is rotatably connected to the second guide member 15, and the rotation axis of the clamping member 13 extends along a second direction.

[0070] Specifically, the clamping member 13 can be rotatably connected to the telescopic part 12 and the second guide member 15 respectively, and the rotation axes of the clamping member 13 relative to the rotation axes of the two are not parallel. As a result, the clamping member 13 can be rotated in different directions to make fine adjustments to the angle of contact with the track, so as to better clamp the track.

[0071] The rotatable connection between the clamping member 13, the telescopic part 12, and the second guide member 15 can also be achieved through bearings.

[0072] For example, the telescopic assembly 10 also includes a first bearing 16 disposed at the extended end of the telescopic part 12, and the clamping member 13 is rotatably connected to the telescopic part 12 through the first bearing 16.

[0073] Specifically, depending on the actual situation, the clamping member 13 may have a first rotating shaft, and the telescopic part 12 may be connected to the outer ring of the first bearing 16, with the first rotating shaft passing through the bearing hole of the first bearing 16. Alternatively, the telescopic part 12 may have a first rotating shaft, and the clamping member 13 may be connected to the outer ring of the first bearing 16.

[0074] For example, the telescopic assembly 10 also includes a second bearing 17 disposed at one end of the second guide member 15 near the clamping member 13, and the clamping member 13 is rotatably connected to the second guide member 15 through the second bearing 17.

[0075] Specifically, depending on the actual situation, the clamping member 13 may have a second rotating shaft, the second guide member 15 may be connected to the outer ring of the second bearing 17, and the second rotating shaft may pass through the bearing hole of the second bearing 17. Alternatively, the second guide member 15 may have a second rotating shaft, and the clamping member 13 may be connected to the outer ring of the second bearing 17.

[0076] In one embodiment, please refer to Figure 2 The telescopic part 12 includes a telescopic rod 121 and a connecting member 122. The connecting member 122 is disposed on the telescopic rod 121. The hooks 211 are rotatably disposed on the connecting member 122. The driving part 22 is a clamping cylinder. The clamping cylinder includes a cylinder barrel 221 and a piston rod 222. The piston rod 222 is disposed in the cylinder barrel 221. The piston rod 222 and the cylinder barrel 221 drive the two hooks 211 to rotate relative to the connecting member 122 through relative movement, so as to achieve mutual approach or mutual distance.

[0077] Specifically, the telescopic part 12 extends and retracts, causing the connecting member 122 and the clamping assembly 20 to move toward the side closer to the track or away from the track. The connecting member 122 is used to connect the telescopic rod 121 and the clamping assembly 20, and its specific structure is not limited.

[0078] For example, connector 122 includes two spaced-apart connecting plates and two spaced-apart connecting shafts. The two ends of the two connecting shafts are respectively connected to the connecting plates. A portion of the clamping assembly 20 is located in the space between the two connecting plates. Two hooks 211 are rotatably mounted on the connecting shafts.

[0079] It should be noted that, due to the connection plate 122, the distance between the two hooks 211 is relatively large, and the two hooks 211 can be used to clamp rails made of I-beams, such as I-beams with a width of 380mm.

[0080] The piston rod 222 is located at least partially within the cylinder 221, and by extending and retracting along the axial direction of the cylinder 221, it drives the two hooks 211 to rotate. In other words, the linear motion of the piston rod 222 is converted into the rotation of the hooks 211 to clamp or disengage from the track.

[0081] It should be noted that the specific connection position between the hook 211 and the clamping cylinder will affect the extension and retraction method of the clamping cylinder.

[0082] For example, please refer to Figure 4 The piston rod 222 is driven to connect with the hook 211. At this time, the extension and retraction of the piston rod 222 causes the hook 211 to rotate, while the cylinder 221 remains stationary relative to the connecting member 122. It can be fixed to the connecting member 122 or connected to other structures.

[0083] For example, cylinder 221 is driven to connect to hook 211. In this case, piston rod 222 needs to remain stationary relative to connecting member 122; it can be fixed to connecting member 122 or connected to other structures. Thus, the movement of cylinder 221 relative to piston rod 222 drives hook 211 to rotate.

[0084] It should be noted that the specific positions of cylinder 221 and piston rod 222 are not limited. Piston rod 222 can be located on the side of cylinder 221 closer to the track, or piston rod 222 can be located on the side of cylinder 221 away from the track.

[0085] In one embodiment, please refer to Figure 4 The clamping part 21 also includes a transmission rod 212. One of the piston rod 222 and the cylinder 221 is drivenly connected to one end of the transmission rod 212, and the other end of the transmission rod 212 is rotatably connected to the hook 211. Through the transmission rod 212, the arrangement of the hook 211 can be made more flexible, and it is also convenient for the clamping cylinder to drive the hook 211 to rotate relative to the connecting member 122.

[0086] Specifically, the clamping cylinder may not be directly connected to the hook 211 for drive; instead, a transmission rod 212 can be installed between the two for transmission.

[0087] It can be that the piston rod 222 is driven to one end of the transmission rod 212, and the other end of the transmission rod 212 is rotatably connected to the hook 211. Alternatively, the cylinder 221 is driven to one end of the transmission rod 212, and the other end of the transmission rod 212 is rotatably connected to the hook 211.

[0088] For example, one end of the transmission rod 212 connected to the clamping cylinder can rotate relative to the clamping cylinder, and the other end of the transmission rod 212 connected to the hook 211 can rotate relative to the hook 211.
