Description

Technical Field

[0001] This utility model belongs to the field of cable towing technology, specifically relating to a cable towing vehicle and a cable towing device. Background Technology

[0002] The cable trailer of the self-propelled train is connected to the machine roadway advance support through a pushing frame. When the machine roadway advance support moves forward, it pushes against the pushing frame, which in turn drives the cable trailer. However, the working surface in the roadway is uneven and has multiple slope change points. When passing through the slope change points, the cable trailer is prone to slipping on the track, causing the pushing frame between the machine roadway advance support and the cable trailer to bear huge external forces. When the force is severe, it will crack and deform, resulting in a safety accident. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a cable tractor that solves the problem that existing cable tractors are prone to slippage before and after the slope change point, which exerts a large force on the pushing frame.

[0004] In view of this, the purpose of this utility model is also to provide a cable dragging device.

[0005] To achieve the above objectives, the first technical solution of this utility model is as follows: a cable tractor includes a track, a connector, and a vehicle body. The vehicle body is slidably connected to the track. One end of the connector is connected to the vehicle body, and the other end is detachably connected to the track. When the cable tractor passes near a slope change point, the connector is connected to the track, so that the vehicle body is relatively fixed to the track, thereby preventing the vehicle body from sliding off the track.

[0006] Furthermore, the track is provided with a first connecting part, and the end of the connector away from the vehicle body is detachably connected to the first connecting part.

[0007] Furthermore, the vehicle body includes a base plate and upright legs mounted on the base plate, the base plate being slidably connected to the track.

[0008] Furthermore, at least two vehicle bodies are provided, with adjacent vehicle bodies connected by a connecting chain, and the tops of the uprights on adjacent vehicle bodies connected by a flexible cable tray.

[0009] Furthermore, a second connecting part is provided on the base plate at a position corresponding to the connecting chain, and the two ends of the connecting chain are respectively connected to the second connecting part on the adjacent vehicle body.

[0010] Furthermore, the connecting chains are configured as two, located on both sides of the vehicle body respectively.

[0011] Furthermore, the vehicle body also includes a diagonal brace, one end of which is connected to the upright leg and the other end of which is connected to the base plate.

[0012] Furthermore, at least two diagonal braces are provided, and they are evenly distributed around the upright leg.

[0013] The second technical solution of this utility model is implemented as follows: a cable towing device includes a machine lane advance support, a pushing frame and the aforementioned cable towing vehicle, wherein the machine lane advance support is connected to the body of the cable towing vehicle through the pushing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a connector on the vehicle body, when encountering a slope change point, the end of the connector away from the vehicle body is connected to the track, which prevents the vehicle body from sliding on the track and exerting a large force on the pushing frame, avoiding cracking and deformation of the pushing frame, and ensuring the safety of cable dragging operation.

[0022] Example 1

[0023] The cable tractor provided in this embodiment has the following structure: Figure 2 , Figure 3 As shown, it includes a track 1, a connector 2, and a vehicle body 3. The vehicle body 3 is slidably connected to the track 1. One end of the connector 2 is connected to the vehicle body 3, and the other end is detachably connected to the track 1. When the cable tractor passes near the slope change point, the connector 2 is connected to the track 1, so that the vehicle body 3 is relatively fixed to the track 1, thereby preventing the vehicle body 3 from sliding off the track 1 and reducing the force on the pushing frame 6.

[0024] Based on the above structure, the cable towing vehicle has a connector 2 installed on the vehicle body 3. When encountering a slope change point, the end of the connector 2 away from the vehicle body 3 is connected to the track 1. This prevents the vehicle body 3 from sliding on the track 1 and exerting a large force on the pushing frame 6, thus avoiding cracking and deformation of the pushing frame 6 and ensuring the safety of the cable towing operation.

[0025] In some embodiments of this application, the track 1 is provided with a first connecting part, and the end of the connector 2 away from the vehicle body 3 is detachably connected to the first connecting part.

[0026] Specifically, the first connecting part is a chain link. When the machine roadway advance support 7 moves the cable trolley through the pushing frame 6, there are two situations: First, the machine roadway advance support 7 is not in contact with the track 1. At this time, the other end of the connector 2 is removed from the chain link, the vehicle body 3 is not connected to the track 1, the track 1 is stationary in the roadway, and the machine roadway advance support 7 drives the vehicle body 3 of the cable trolley to slide on the track 1 to achieve cable dragging. Second, the vehicle body 3 of the cable trolley moves to one end of the track 1, and the machine roadway advance support 7 contacts the other end of the track 1. The movement of the machine roadway advance support 7 will drive the track 1 and the vehicle body 3 to move together. At this time, it is necessary to fasten the connector 2 to the chain link on the track 1 to prevent the vehicle body 3 from deviating from the track 1, especially before and after the slope change point, to prevent the vehicle body 3 from sliding on the track 1 and reduce the force on the pushing frame 6.

[0027] In some embodiments of this application, the vehicle body 3 includes a base plate 31 and upright legs 32 disposed on the base plate 31, the base plate 31 being slidably connected to the track 1; in this embodiment, the upright legs 32 are provided to support the cables and liquid pipes, and the base plate 31 is provided to increase the contact area between the upright legs 32 and the track 1, thereby ensuring the connection stability and movement stability of the upright legs 32 and the track 1.

[0028] In some embodiments of this application, at least two vehicle bodies 3 are provided, and two adjacent vehicle bodies 3 are connected by a connecting chain 4. The top ends of the upright legs 32 on adjacent vehicle bodies 3 are connected by a flexible cable tray 5.

[0029] In this embodiment, the cable and liquid pipe are placed on the flexible cable tray 5, and at least two vehicle bodies 3 are provided to support multiple parts of the cable and liquid pipe, ensuring the cable dragging effect.

[0030] like Figure 4 As shown, in some embodiments of this application, a second connecting part is provided on the base plate 31 at a position corresponding to the connecting chain 4, and the two ends of the connecting chain 4 are respectively connected to the second connecting part on the adjacent vehicle body 3.

[0031] Specifically, the second connecting part is a chain link or saddle ring, which is set on the side of the base plate 31 parallel to the track 1.

[0032] The existing technology places the connecting chain 4 in the middle of the adjacent vehicle body 3. When the cables on the cable tractor move forward with the vehicle body 3 and gather together, the connecting chain 4 will enter the gap between the track 1 and the base plate 31. If the staff does not check properly when the cable tractor is towing, the connecting chain 4 will break, which will cause the vehicle body 3 to slip, especially when encountering a change of slope.

[0033] In this embodiment, by setting a second connecting part on the side of the base plate 31, the connecting chain 4 is set on the side of the adjacent vehicle body 3, which prevents the connecting chain 4 from entering the gap between the track 1 and the base plate 31 as the vehicle body 3 moves, reduces the risk of the connecting chain 4 being broken, and improves the safety of electric towing.

[0034] In some embodiments of this application, the connecting chain 4 is configured as two chains, located on both sides of the vehicle body 3 respectively, to ensure the stability of the force when the vehicle body 3 moves.

[0035] In some embodiments of this application, the vehicle body 3 further includes a diagonal brace 33, one end of which is connected to the upright leg 32 and the other end is connected to the base plate 31. The diagonal brace 33 is used to further support the upright leg 32 and prevent the upright leg 32 from tilting during use.

[0036] In some embodiments of this application, at least two diagonal braces 33 are provided and are evenly distributed around the upright leg 32 to ensure the uniformity of force when the diagonal braces 33 support the upright leg 32.

[0037] Example 2

[0038] The cable dragging device provided in this embodiment has the following structure: Figure 1 As shown, it includes a machine lane advance support 7, a pushing frame 6, and the cable tractor described in Embodiment 1. The machine lane advance support 7 is connected to the vehicle body 3 of the cable tractor through the pushing frame 6.

[0039] In this embodiment, the advance support 7 of the machine lane drives the moving frame 6 to move, which in turn drives the body 3 of the cable tractor to move, thereby achieving the dragging of the cable. During the dragging process, the connecting chain 4 will not get stuck in the gap between the track 1 and the base plate 31, avoiding the possibility of breakage. At the slope change point, the body 3 can be stably connected to the track 1, avoiding the impact on the moving frame 6 when the trolley is pulled, thus improving safety.

[0040] The specific method for using the cable dragging device provided in this embodiment is as follows:

[0041] When the machine lane advance support 7 is started, and the machine lane advance support 7 is not in contact with the track 1, the end of the connector 2 away from the car body 3 is not connected to the track 1. The machine lane advance support 7 drives the car body 3 to slide on the track 1 through the pushing frame 6. Adjacent car bodies 3 are stably connected through the connecting chain 4. The upright leg 32 is stably connected to the base plate 31 through the diagonal brace 33, forming a stable support for the flexible cable tray 5, that is, a stable support for the cable and liquid pipe. When the car body 3 moves, the cable is dragged.

[0042] When the machine roadway advance support 7 contacts the track 1, the end of the connector 2 away from the car body 3 is connected to the track 1. The machine roadway advance support 7 drives the car body 3 and the track 1 to move in the roadway through the pushing frame 6. When encountering a slope change point, the relative position of the car body 3 and the track 1 is fixed. The car body 3 will move in the roadway under the drive of the track 1 without slipping. The force on the pushing frame 6 is small, which can avoid the deformation and cracking of the pushing frame 6.

[0043] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
