Abstract

The invention relates to a track quick connector, belonging to a connecting device of a hanging rail under a mine, wherein one end of a track is an inclined end surface, an arc-shaped connecting lug is fixed above the inclined end surface, a female connector is arranged below the inclined end surface, the other end of the track is a vertical end surface, two parallel connecting lugs are fixed above the vertical end surface, a concentric hole is formed in the connecting lugs, a male connector is fixed below the end surface, the female connector of the track is sleeved on the male connector during connection, the two track connecting lugs are combined together, and a connecting pin penetrates through the hole to be connected and fixed.

Description

Track fast joint

Technical field:

The present invention relates to the linkage of mining hanger rail.

Background technology:

Under coal mine in assistant conveyance, adopt the means of transportation of monorail crane more and more extensive, the connection of its track adopts bolt to be fixedly connected with at present, and this connected mode is not only time-consuming, and safety can not get ensureing, because mining roadway big rise and fall, when track changes direction with tunnel, the joint of track just there will be distortion, joint produces and is uneven, crane by time will truck, even derailing, brings hidden danger to safety.

Summary of the invention:

For avoiding the shortcoming of background technology, the present invention propose a kind of can movable and mild track fast joint.

One end of track is angled end-face, above angled end-face, fix an engaging lug, have arcuate socket on engaging lug, under angled end-face, edge is fixed with female joint, above female joint, there is groove, track other end is perpendicular end surface, and end face top is fixed with two parallel engaging lugs, has concentric holes on engaging lug, under perpendicular end surface, edge is fixed with male joint, male joint is scoop shape, and upper surface is arc, has a groove identical with male joint shape in the middle of female joint.

Advantage of the present invention: install fast, labour intensity is little, rail joint is mild and can activity, has guaranteed steadily passing through of crane, has eliminated crane interruption of service.

Accompanying drawing explanation:

Fig. 1 is structural representation of the present invention.

Fig. 2 is the top view of Fig. 1

Fig. 3 is the structural representation of male joint

Fig. 4 is the structural representation of female joint

The specific embodiment:

One of track 1 is processed into the end face having a down dip, gradient is 1/2nd of circular arc angle, above angled end-face, weld an engaging lug 3, on engaging lug 3, there is arcuate socket, the center of circle of arc is positioned at the lower edge of angled end-face, the angle of circular arc is 5～10 degree, under angled end-face along being welded with female joint 5,5 grooves that have a scoop shape in female joint; The other end of track 1 is perpendicular end surface, two parallel engaging lugs 2 of perpendicular end surface top welding, on engaging lug 2, there is concentric holes, between two engaging lugs 2, distance is equal to or greater than the thickness of engaging lug 3, under perpendicular end surface, along being welded with male joint 4, male joint 4 is scoop shape, identical with the groove shape size in female joint 5, the upper surface of male joint 4 is arc, is convenient to the activity of male joint 4.When track 1 connects, first a track is sling and fixed, then the female joint of another root track 15 is enclosed within the male joint 4 of trapped orbit, then engaging lug 3 is inserted between two engaging lugs 2, penetrate in hole fixingly with pin, connection completes.
