Description

Fixing device for butt joint of rail

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 fixing device at a butt joint of a rail.

The technical scheme includes that a sleeper is arranged at the rail butt joint, positioning grooves are formed in two sides of a rail on the sleeper, a rail fixing pressing plate screw hole is formed in one side of each positioning groove, a positioning block is arranged on one side of each rail fixing pressing plate and inserted into each positioning groove, the rail fixing pressing plates are pressed on bases on two sides of the rail interface connection portion, the rail fixing pressing plates are fixed through rail fixing pressing plate bolts, and the rail fixing pressing plates are connected into the rail fixing pressing plate screw holes of the sleeper through the rail fixing pressing plate bolts.

Establish the stopping mechanism at track fixed pressing plate, stopping mechanism be equipped with the sloping block in the outside of track fixed pressing plate's locating piece, be equipped with the voussoir in the sloping block side, open the opposite side of constant head tank on the sleeper has voussoir clamp plate screw, the voussoir clamp plate is pressed on the voussoir, the voussoir clamp plate passes through voussoir clamp plate bolt fastening, voussoir clamp plate bolted connection is in the voussoir clamp plate screw of sleeper.

The invention has the following technical effects that the fixation of the butt joint of the rails is strengthened, when a mine car or a shuttle car brakes at the butt joint of the rails, the passing of the holding claws is not influenced, and the butt joint of the rails is not easy to deform and dislocate, so that the derailment accident is prevented.
