2. The track butt joint fixing clamp sleeve according to claim 1, wherein: a rail waist guard plate (14) is arranged on the hook top of the fixed hook (1).

Technical Field

The invention belongs to a track matching facility of underground or aboveground mine cars, shuttle cars and other transportation equipment 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 clamping sleeve for a butt joint of a rail.

The technical scheme of the invention is that the rail butt joint fixing clamping sleeve comprises a fixing clamping hook, wherein a hook groove matched with the rail bottom of a rail is formed in the fixing clamping hook, a clamping hook bolt hole is formed in the fixing clamping hook, a clamping hook pressing block is arranged on the opposite surface of the fixing clamping hook, an inclined wedge groove is formed in the clamping hook pressing block, an inclined wedge is arranged in the inclined wedge groove, and a fixing piece is arranged on the lower side of the inclined wedge.

The hook top of the fixed hook is provided with a rail waist guard plate.

The invention has the following technical effects that the fixation of the butt joint of the rail is strengthened, when transportation equipment such as a mine car or a shuttle car brakes, the passing of the holding claw is not influenced, the butt joint of the rail is not easy to deform and dislocate, the derailment accident is prevented, the wedge can prevent the loosening of the clamping hook pressing block, and the rail web guard plate can increase the strength of the rail web.
