Description

Technical Field

[0001] The utility model relates to the technical field of track vehicle traction connection, in particular to a track vehicle traction connection device. Background Technique

[0002] Rail transit facilities are currently in rapid development in China. Whether it is the high-speed railway between cities or the subway within the city, the number of rail transit projects under construction and in operation is huge. Rail traction refers to using a certain mechanical device to tow a non-powered locomotive or carriage on the track to a designated position. Rail traction equipment can be divided into three types: electric rail tractors, network rail and road tractors, and rail and road dual-purpose tractors. In the construction and maintenance of rail transit facilities, various traction devices are required on the operating track to transport and move rail vehicles.

[0003] As disclosed in the authorized publication number CN216374548U, a track vehicle traction connection device is disclosed, which belongs to a kind of track equipment component. The technical solution adopted by the utility model is: including a connection hole position, a connection pin and a driving mechanism for driving the connection pin to move. The connection hole position is provided with an inwardly concave positioning groove. The vehicle or equipment to be towed inserts a connection mechanism with holes into the positioning groove. The two side surfaces of the positioning groove are respectively provided with pin holes, and the pin holes on the two side surfaces and the holes on the connection mechanism of the vehicle or equipment to be towed are coaxial. The connection pin is arranged coaxially with the two pin holes. The diameter of the connection pin is smaller than the size of the pin hole. The other end of the connection pin is connected to the driving mechanism, and the driving structure drives the connection pin to insert into the two pin holes and the holes of the connection mechanism of the vehicle or equipment to be towed. The advantages mentioned in this track vehicle traction connection device are: it can quickly connect the towing vehicle and the vehicle to be towed, and uses hydraulic drive connection, with high operation safety.

[0004] However, for the connection device mentioned in this patent, the insertion method of the connection pin during connection needs to be transmitted and inserted through mechanical movement, without direct pinning. This method causes a large amount of mechanical loss during long-term mechanical transmission, resulting in easy damage to the overall device. Content of the Utility Model
