Description

Technical Field

[0001] The utility model relates to the technical field of train traction, in particular to a train drawbar mechanism. Background Art

[0002] Trains can be classified into railway trains (i.e., trains) and road trains (such as articulated trucks, truck trains, etc.) according to their types. Among them, railway trains can be classified into freight trains for carrying goods and passenger trains for carrying passengers according to the load, and there are also passenger-cargo trains that combine the two. In China, trains are classified into regular-speed trains, express train series, high-speed trains (CRH) series, etc. according to their speeds.

[0003] However, in the prior art, when the existing vehicle trains are in traction use, generally only an integrated drawbar is used to tow the vehicle to move. When the vehicle stops due to braking, it generally relies on the drawbar itself to maintain, and there is no structure that can buffer the movement, which easily reduces the service life of the drawbar. The ordinary drawbar cannot tow multiple sections of vehicles to continue pulling goods, and it does not have the same drawbar telescopic range as the train carriage, so it cannot guarantee the stability and safety during driving. Summary of the Utility Model

[0004] The utility model provides a train drawbar mechanism, which solves the technical problems that the drawbar described above does not have a structure that can buffer movement and does not have a telescopic range structure, resulting in the inability to pull goods with multiple sections of vehicles.

[0005] The solution of the utility model to the above technical problems is as follows: A train drawbar mechanism includes two mounting seats. A connecting rod body is provided at the bottom of each mounting seat. An activity groove is provided on one side of each connecting rod body. Bearings are provided at the top and bottom of the inner part of each activity groove. Two rotating columns are connected by four bearings at the top and bottom of the inner parts of the two activity grooves. A rotating rod is provided on one side of each rotating column. A buffer connection component is provided between the opposite sides of each pair of rotating rods.

[0006] The beneficial effects of the utility model are as follows: The mounting seats mainly play a role in facilitating support and also facilitating the fixation of bolts at the bottom of the vehicle. The provided connecting rod bodies can play a supporting role. The activity grooves can facilitate the storage of bearings. The bearings can facilitate the rotation of the rotating columns. The rotating columns can enable the rotating rods to rotate and move, so as to facilitate the movement of the vehicle when it rotates. The buffer connection component can facilitate buffering the movement when the vehicle brakes and also facilitate its telescopic movement range.

[0007] On the basis of the above technical solutions, the utility model can also be improved as follows.

[0008] Furthermore, the buffer connection assembly includes two buffer columns and a connection box body, the two buffer columns are arranged at opposite sides of the two rotating rods, and a baffle is arranged on one side of each buffer column.

[0009] The beneficial effect of adopting the above further solution is that the buffer column can be easily connected and fixed inside the connection box body, and the baffle can transmit and isolate the force on the buffer column.

[0010] Furthermore, a plurality of springs are provided on both sides of the interior of the connection box body, and two buffer frames are connected to both sides of the interior of the connection box body through the plurality of springs.

[0011] The beneficial effect of adopting the above further solution is that the spring can bring the buffer frame to provide buffering force when the vehicle is pulled.

[0012] Furthermore, a support plate is provided between both sides of the interior of the connection box body, and a plurality of dampers are provided on both sides of the support plate near the top and the bottom.

[0013] The beneficial effect of adopting the above further solution is that the support plate can support the damper, and the damper can support the buffer plate.

[0014] Furthermore, four buffer plates are connected to both sides of the support plate through a plurality of dampers.

[0015] The beneficial effect of adopting the above further solution is that the buffer plate can buffer the moving buffer column and baffle.

[0016] Furthermore, air bags are provided on both sides of the support plate near the center.

[0017] The beneficial effect of adopting the above further solution is that the airbags can easily share the impact force.

[0018] Beneficial effect: By using the buffer connection component, the vehicle's brakes can be buffered instead of relying on the tow bar itself to maintain it. To a certain extent, the service life of the tow bar can be improved. The buffer connection component has a movable and retractable structure inside, which can facilitate multiple vehicles to continue to pull goods, and can ensure stability and safety during driving as much as possible.

[0027] Embodiment 1

[0028] As Figures 1 - 3 shown, a train drawbar mechanism of the present utility model includes two mounting seats 1. A connecting rod body 2 is provided at the bottom of each mounting seat 1. An activity groove 3 is provided on one side of each connecting rod body 2. Bearings 4 are provided at the top and bottom surfaces inside each activity groove 3. Two rotating columns 5 are connected by four bearings 4 at the top and bottom surfaces inside the two activity grooves 3. A rotating rod 6 is provided on one side of each rotating column 5. A buffer connection assembly 7 is provided between the opposite sides of each rotating rod 6.

[0029] Embodiment 2

[0030] As Figures 1 - 3As shown in the figure, the buffer connection component 7 includes two buffer columns 71 and a connection box body 72. The two buffer columns 71 are arranged on the opposite sides of the two rotating rods 6. A baffle 73 is arranged on one side of each buffer column 71. A plurality of springs 74 are arranged on both sides inside the connection box body 72. Two buffer frame bodies 75 are connected to both sides inside the connection box body 72 through a plurality of springs 74. A support plate 76 is arranged between both sides inside the connection box body 72. A plurality of dampers 77 are arranged near the top and bottom on both sides of the support plate 76.

[0031] In this embodiment, the buffer column 71 can facilitate connection and fixation inside the connection box body 72. The baffle 73 can transfer and isolate the force on the buffer column 71. The spring 74 can drive the buffer frame body 75 to buffer the pulling force of the vehicle. The support plate 76 can support the damper 77, and the damper 77 can support the buffer abutment plate 78.

[0032] Embodiment 3

[0033] As Figures 1 - 3 shown, four buffer abutment plates 78 are connected to both sides of the support plate 76 through a plurality of dampers 77. Air bags 79 are arranged near the center on both sides of the support plate 76.

[0034] In this embodiment, the buffer abutment plate 78 buffers the buffer column 71 and the baffle 73 that move over. The air bag 79 can facilitate sharing the impact force together.

[0035] Working principle:

[0036] When vehicle braking is required, the impact force of the buffer column 71 and the baffle 73 can be buffered by relying on the damper 77, the buffer abutment plate 78 and the air bag 79 inside the connection box body 72, rather than relying on the traction rod itself to maintain. To a certain extent, the service life of the traction rod can be improved. Using the spring 74 and the buffer frame body 75 can prevent the inserted buffer column 71 and baffle 73 from being pulled out, and can also buffer the impact when being pulled. There is a structure that can move and expand inside the device, which can facilitate multiple-section vehicles to continue pulling goods, and can maliciously ensure the stability and safety during driving as much as possible.
