Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance, in particular to a maintenance cart. Background Art

[0002] Railways use two parallel rails to guide trains. Railway transportation is the most efficient mode of transportation on known roads. Railways can provide extremely smooth and hard media for train wheels to roll on with minimal friction. In order to ensure the safe operation of railway transportation, maintenance personnel of the locomotive depot need to be divided into groups to conduct comprehensive maintenance on railway locomotives, with 4-6 people in each group. A large number of tools and spare parts are needed during the maintenance process.

[0003] Traditional railway maintenance trolleys have the following defects in daily use:

[0004] 1. The traditional maintenance trolley used for railways has a simple structure, and the distance between the rollers is fixed and cannot be adjusted. In real life, multiple tracks are parallel, and the distances between different tracks are different. When the distance between adjacent tracks is narrow, the maintenance trolley cannot pass through, and the practicality is low;

[0005] 2. The traditional maintenance trolley for railways lacks a shock-absorbing mechanism. When the trolley moves, it bumps up and down with a large arc, which causes discomfort to the maintenance personnel. Therefore, we propose a new type of maintenance trolley. Utility Model Content

[0006] The utility model provides a maintenance cart to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The sprocket wheel of the present invention is provided with a toothed wheel which is arranged on the top of the toothed wheel, and the toothed wheel is provided with a toothed wheel on the bottom of the toothed wheel.

[0009] As a further improvement of the technical solution: the support rod, the casing, the damper, the shock absorbing spring and the shock absorbing airbag are all arranged between the vehicle plate and the top plate.

[0010] As a further improvement of the technical solution: the output end of the dual-axis motor is fixedly mounted at the center of the front wheel.

[0011] As a further improvement of the technical solution: the guide block is slidably connected to the guide rod.

[0012] As a further improvement of the technical solution: a rocker is fixedly mounted on one end of the bidirectional screw.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Manually rotate the bidirectional screw, which drives the screw block to move. The guide block and guide rod can help the screw block move more steadily on the bidirectional screw. The screw block drives the rear frame to move closer or farther away from each other, so as to adjust the distance between the rear wheels. This allows the maintenance trolley to pass through tracks with different intervals, which is convenient for maintenance operations on equipment on both sides of tracks with different intervals, and is highly practical.

[0015] 2. The damper and shock-absorbing spring are used together to provide the first shock absorption for the maintenance vehicle, and the shock-absorbing airbag can provide the second shock absorption for the maintenance vehicle. The multi-layer shock-absorbing mechanism can effectively reduce the vibration amplitude during the movement of the maintenance vehicle, making it convenient for daily use.

[0030] See also Figure 1 and Figure 3 The output end of the dual-axis motor 13 is fixedly mounted on the center of the front wheel 12. The dual-axis motor 13 drives the front wheel 12 to move, thereby driving the entire maintenance vehicle to move, which is convenient for daily mobile operations near the railway.

[0031] See also Figure 1-2 and Figure 4 The guide block 20 is slidably connected to the guide rod 15. By using the guide block 20 and the guide rod 15 in combination, the screw block 17 can be forced to move horizontally only under the action of the bidirectional screw 16, and will not rotate synchronously with the bidirectional screw 16, so that the screw block 17 moves on the bidirectional screw 16 more stably.

[0033] The working principle of the utility model is as follows: when using the maintenance vehicle, the maintenance personnel pushes the push rod 10 to start the double-axis motor 13, and the double-axis motor 13 provides power to make the maintenance vehicle move forward, and the maintenance tools are placed in the tool box 8, which is convenient for the maintenance and repair of the switch machine or other components of the signal machine running on both sides of the track. The impurity collection box 9 can collect and process the impurities generated during the maintenance process. When multiple tracks are parallel and the distance between adjacent tracks is relatively narrow, the maintenance personnel can manually rotate the bidirectional screw 16, and the bidirectional screw 16 drives the screw block 17 to move, and the guide block 20 and the guide rod 15 are used in conjunction with each other. It can assist the screw block 17 to move more stably on the bidirectional screw rod 16. The screw block 17 drives the rear frame 18 to move closer or farther away from each other, so as to adjust the distance between the rear wheels 19, so that the maintenance vehicle can pass through tracks with different intervals, which is convenient for maintenance operations on equipment on both sides of tracks with different intervals. It is highly practical. When the maintenance vehicle is moving, the damper 4 and the shock-absorbing spring 5 are used together to perform the first shock absorption during the movement of the maintenance vehicle. The shock-absorbing airbag 6 can perform the second shock absorption on the maintenance vehicle. The multi-layer shock-absorbing mechanism can effectively reduce the vibration amplitude during the movement of the maintenance vehicle, which is convenient for daily use.
