Abstract

The utility model discloses a fixed cassette of track butt joint, including a pair of track outside cassette, the inboard kicking block of a pair of track has the pothook in the track outside cassette top outside, and the hook groove and the track outside rail end of pothook suit, and a pair of track outside cassette passes through bolted connection, is connected with the ejector pin on the kicking block, and the ejector pin of the inboard kicking block of a pair of track is through controlling the screw nut and connecting. The utility model discloses there is following technological effect, it is fixed to reinforce track butt joint department, when transportation equipment such as mine car or shuttle when the track braking, firstly do not influence embracing the passing through of claw, secondly track butt joint department is difficult to the track and warp the dislocation, prevents the emergence of derailment accident, is connected with the ejector pin on the kicking block, and the ejector pin of the inboard kicking block of a pair of track is connected through controlling the silk nut, from the inboard with track outside cassette chucking, prevents not hard up, can increase the intensity of rail waist.

Description

Fixing clamping seat for butt joint of rail

Technical Field

The utility model belongs to the supporting facility in supplementary transportation's such as mine mining's underground or aboveground mine car and shuttle car in mineral exploitation track, mainly used track butt joint department is fixed.

Background

The tracks of underground or aboveground mine cars, shuttle cars and other transportation equipment for mineral exploitation mostly adopt GB11264 tracks or YB5055 tracks, and the connection mode at the butt joint of the two tracks is as follows: the rail web at the rail joint is provided with a connecting hole, and the rail web is clamped from two sides through clamping plates, bolts and nuts. The mine transportation transport equipment such as mine cars and shuttle cars adopts a vehicle-mounted emergency braking mode that a clamping claw is hooked on the lower side of a rail head of a rail, a brake rod applies pressure from a rail tread to carry out rail clamping braking, and a clamping plate, a bolt and a nut which are connected at the butt joint of two rails can block the clamping claw from passing through, so that the braking is influenced, and safety accidents are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fixed cassette of track butt joint.

The technical scheme of the utility model, a fixed cassette of track butt joint, including a pair of track outside cassette, the inboard kicking block of a pair of track has the pothook in the track outside cassette top outside, and the hook groove and the track outside rail end of pothook suit, and a pair of track outside cassette passes through bolted connection, is connected with the ejector pin on the kicking block, and the ejector pin of the inboard kicking block of a pair of track is through controlling the screw nut and connecting.

The utility model discloses there is following technological effect, it is fixed to reinforce track butt joint department, when transportation equipment such as mine car or shuttle when the track braking, firstly do not influence embracing the passing through of claw, secondly track butt joint department is difficult to the track and warp the dislocation, prevents the emergence of derailment accident, is connected with the ejector pin on the kicking block, and the ejector pin of the inboard kicking block of a pair of track is connected through controlling the silk nut, from the inboard with track outside cassette chucking, prevents not hard up, can increase the intensity of rail waist.
