Technical Field

The invention belongs to a track matching facility for auxiliary transportation of underground or aboveground mine cars, shuttle cars and the like for mineral exploitation, and is mainly used for fixing a butt joint of a track.

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.

Disclosure of Invention

The invention aims to provide a rail butt joint fixing clamp.

The technical scheme includes that the rail butt joint fixing clamp comprises a rail inner side clamp, a fixing pressure plate clamping groove is formed in the bottom of the rail inner side clamp outwards, a through groove matched with a rail bottom on one side of a rail is formed in the inner side of the rail inner side clamp, the rail bottom on one side of the rail is sleeved in the through groove, and the fixing pressure plate is embedded into the fixing pressure hook clamping groove from one end of the fixing clamp and is fixed to the rail bottom of the rail from the outer side of the rail.

The rail fastening wedge groove is arranged on the inner side clamp of the rail and opposite to the rail bottom of the rail, and a pair of rail fastening wedges which are oppositely inserted are inserted into the rail fastening wedge groove.

The fixed pressing plate clamping groove is provided with a track inner side clamping wedge groove, and a fixed pressing plate fastening wedge is inserted into the track inner side clamping wedge groove.

The outer side wall of the fixed pressing plate is provided with a fixed pressing plate compaction wedge groove, and a fixed pressing plate compaction wedge is inserted into the fixed pressing plate compaction wedge groove.

There is a waist guard plate above the rail inner side card and in contact with the rail.

The invention has the following technical effects that the fixation of the butt joint of the rails is strengthened, when transportation equipment such as a mine car or a shuttle car brakes on the rails, the passing of the holding claws is not influenced, the butt joint of the rails is not easy to deform and dislocate, the occurrence of derailment accidents is prevented, the wedges can prevent the loosening of the rails and the fixed pressing plate, and the rail waist guard plate can increase the strength of the rail waist.
