Problems solved by technology

[0002] The connecting pin of the mine car is an indispensable component of the mine transport vehicle. The pin connects each section of the transport vehicle into a train through the pin hole and the link on the transport vehicle. Unreliable and other shortcomings. During the transportation of trains in coal mines, there have been many accidents in the inclined lanes and the slopes of mine cars after the bolts of mine cars jumped out and slipped off. The large loss will have a very bad impact on the safe production of the coal mine; the mine trolley is a means of transportation specially used to transport personnel during the coal mine production process. It will cause fatal injury to all the people who ride in the mine, and may cause serious serious accidents that cause many casualties; in order to prevent the occurrence of such serious accidents, special mandatory regulations have been made in the coal mine production safety regulations. The coal mine production process The connecting pin of the mine pedestrian vehicle specially transporting personnel in the mine must have a reliable anti-detachment device

Embodiment Construction

[0013] according to figure 1 , figure 2 As shown, the pin body (1) is fixedly connected with the lifting ring (2), and the effective length of the pin body (1) between the lower edge of the lifting ring (2) and the stop pin (7) is greater than the length of the connection hole of the mine pedestrian vehicle. The center of the pin body (1) has a round hole (3), and the round hole (3) communicates with the T-shaped square hole (6). There is a W-shaped spring (8) in the T-shaped square hole (6). The upper mouth of the spring (8) is fixedly connected with a stop pin (7) respectively, and the stop pin (7) protrudes outward in the holes on both sides of the T-shaped square hole (6), exceeding the surface of the pin body (1). The total length of the surface of the protruding pin body (1) of each stop pin (7) is greater than the diameter of the connecting hole of the mine pedestrian vehicle, and the middle hole (3) runs through the lock (4) up and down, and the lock (4) falls to a ...
