Description

Technical Field

[0001] The invention relates to the technical field of transporting, and in particular to a cart pulling device. Background Art

[0002] The car bodies of rail vehicles such as trains need to be frequently transferred between various workstations during the manufacturing process. Usually, a tractor is used to connect the car body and drag the car body along the rails. Usually, a train coupler is installed on the car body as the connection between the car body and the tractor. However, during the car body production and manufacturing process, the car body needs to be transferred before the individual couplers are installed due to problems with the installation process sequence, or the couplers are not purchased in time due to the fast progress of the car body production. The car body cannot be connected to the tractor, so the tractor cannot be used during the transfer process and needs to be pushed by manpower. The pushing process is difficult to organize personnel, the transfer efficiency is low, and there are safety risks.

[0003] Therefore, in this case, it is necessary to design and use a new type of car body without a coupler to pull the car, so as to connect the car body with the tractor and realize the rapid transportation of the car body. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a vehicle pulling device for pulling a vehicle when a vehicle body is not equipped with a vehicle hook.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A vehicle pulling device, used for connecting a tractor with a vehicle body, the vehicle pulling device comprises a traction ear seat, an impact seat, a connecting frame, a sleeve structure and a plurality of hand pull pins;

[0007] The traction ear seat is fixed on the tractor, and the impact seat is fixed on the vehicle body;

[0008] The traction ear seat and the impact seat bracket are connected through a connecting frame and a sleeve structure;

[0009] The traction ear seat and the connecting frame are detachably connected via a hand-pulled pin;

[0010] The connecting frame and the sleeve structure are detachably connected;

[0011] The sleeve structure is detachably connected to the impact seat.

[0012] The beneficial effects of the present invention are as follows: the hand-pulled pin can be used to achieve quick disassembly, and it is safe and reliable. The device can be used to quickly connect and disconnect the tractor and the vehicle body. When the coupler is not installed, the vehicle body can still be quickly transported. At the same time, the traction height can be adjusted by adjusting the height of the connecting piece with an L-shaped structure. The connection with a variety of impact seats can be achieved through the optimization of the socket structure, thereby improving the versatility and applicability of the tool. By using the tool, the transportation process of a train body without a coupler is reduced from 40 minutes to 20 minutes. At the same time, quick switching can be achieved to tow the coupler and the vehicle body, and the work efficiency is improved by 100%. It not only improves the transportation speed in the state without a coupler, but also reduces the personnel required for transporting the vehicle body, improves work efficiency, reduces safety risks, and is generally recognized by operators.
