Coal mine car connecting mechanism

Abstract

The invention relates to a coal mine car connecting mechanism. Pin holes 4 and 5 are correspondingly formed in the two ends of a first connecting plate; pin holes 3, 1 and 2 are correspondingly formedin the two ends and the middle part of a second connecting plate; one section, with the pin holes 3 and 2, of the second connecting plate is a connecting unit; one section, with the pin holes 1 and 2, of the second connecting plate is an engaging unit; the first connecting plate is hinged with the engaging unit through a cylindrical pin 1 which penetrates into the pin holes 2 and 5; a first groove and a second groove are correspondingly formed in one side, opposite to the engaging unit, of the first connecting plate; the first groove and the second groove form an accommodating space when thepin hole 4 rotates to be coincided with the pin hole 1; a handle 2 is fixedly connected to one side of the first connecting plate; a pin locking device comprises a rotating rod, a cylindrical pin 3, aconnecting rod, a handle 1 and two connecting pieces; the two connecting pieces are fixedly connected with a mine car; one end of the connecting rod is fixedly connected with the middle part of the rotating rod; and the other end of the connecting rod is hinged with the upper end of the cylindrical pin 3. The coal mine car connecting mechanism has the advantages that the connection safety factorof the mine car can be effectively increased, the operation is simple and convenient, the labor intensity of workers can be reduced, and the working efficiency is enhanced.

Description

technical field [0001] The invention relates to a connection device, in particular to a coal mine car connection mechanism, which belongs to the technical field of mine car equipment. Background technique [0002] At present, most of the coal mine cars are connected through three-ring chains, universal chains, steel wire ropes and scraper conveyor chains. Shackle or direct connection, which poses a great hidden danger to the safety of operators, often causes safety accidents such as crowded hands and feet and head crowded by employees due to vehicle connection, and even major accidents such as broken hands and feet and dead people, which bring great harm to the enterprise , families, and individuals have caused irreparable loss of life and property. [0003] The existing mine car vehicle connection method is not only low in safety factor, but also time-consuming and labor-intensive in operation, with high labor intensity, low work efficiency and high labor cost.
