Problems solved by technology

[0002] In the auxiliary transportation of coal mines, the transportation mode of monorail crane is more and more widely used. The connection of the track is currently connected by bolts. Large, when the track changes direction with the roadway, the joints of the track will be deformed, and the joints will be uneven. When the crane passes by, the truck will be driven, or even derailed, which will bring hidden dangers to safety.

Abstract

The invention provides a fast connector for tracks, and belongs to connecting devices of hanging rails under mines. One end of a track is an oblique end face, a connecting lug provided with an arc-shaped hole is fixed onto the oblique end face, a female connector body is arranged under the oblique end face, the other end of the track is a vertical end face, two parallel connecting lugs are fixed onto the vertical end face, the connecting lugs are provided with concentric holes, and a male connector body is fixedly arranged under the vertical end face. During connection, the female connector body of the track is arranged on the male connector body in a sleeved mode, the connecting lugs of two tracks are combined together, and connecting pins penetrate through the holes for connection and fixation. The fast connector for the tracks has the advantages that installation is fast, effort is saved, the connector is smooth and free of head drop, and operation security of a crane is guaranteed.

Description

Technical field: [0001] The invention relates to a connecting device of a mine suspension rail. Background technique: [0002] In the auxiliary transportation of coal mines, the transportation mode of monorail crane is more and more widely used. The connection of the track is currently connected by bolts. Large, when the track changes direction with the roadway, the joints of the track will be deformed, and the joints will be uneven. When the crane passes, it will be trucked or even derailed, which will bring hidden dangers to safety. Invention content: [0003] In order to avoid the disadvantages of the background technology, the present invention proposes a movable and gentle track quick joint. [0004] One end of the track is an inclined end surface, and a connecting ear is fixed above the inclined end surface. There is an arc-shaped hole on the connecting ear. A female joint is fixed on the lower edge of the inclined end surface. There is a groove on the female joint....
