1. The utility model provides a fixed cassette of track butt joint which characterized in that: the track outer clamping seat comprises a pair of track outer clamping seats (1) and a pair of track inner jacking blocks (2), wherein clamping hooks (21) are arranged on the outer side above the track outer clamping seats (1), hook grooves of the clamping hooks (21) are matched with the track bottoms on the outer sides of tracks (3), the track outer clamping seats (1) are connected through bolts (12), ejector rods (21) are connected onto the jacking blocks (2), and the ejector rods (21) of the track inner jacking blocks (2) are connected through left and right screw nuts (22).

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 clamping seat.

The invention adopts the technical scheme that the rail butt joint fixing clamping seat comprises a pair of rail outer side clamping seats and a pair of rail inner side top blocks, wherein a clamping hook is arranged on the outer side above the rail outer side clamping seat, a hook groove of the clamping hook is matched with the rail bottom of the rail outer side, the pair of rail outer side clamping seats are connected through a bolt, a top rod is connected to the top blocks, and the top rods of the pair of rail inner side top blocks are connected through a left screw nut and a right screw nut.

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 derailment accident is prevented, the ejector rods are connected on the ejector blocks, the ejector rods of the pair of ejector blocks at the inner sides of the rails are connected through the left and right screw nuts, the clamping seats at the outer sides of the rails are clamped from the inner sides, the looseness is prevented, and the strength of the rail waist can be increased.
