Description

Fixing jacket 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 jacket for a rail butt joint.

The technical scheme of the invention is that the rail butt joint fixing jacket comprises an outer jacket and an inner jacket, wherein an outer jacket through groove matched with the rail bottom shape on one side of a rail is formed in the inner side of the outer jacket, an outer jacket bottom plate is arranged on the bottom side of the outer jacket, and an outer jacket bolt hole is formed in the outer jacket bottom plate; an inner jacket through groove which is matched with the rail bottom shape at one side of the rail is formed in the inner side of the inner jacket, an outer jacket bottom plate is arranged at the bottom side of the inner jacket, and an inner jacket bolt hole is formed in the inner jacket bottom plate; the jacket fixing bolt penetrates through the outer jacket bolt hole and the inner jacket bolt hole to fix the outer jacket and the inner jacket.

An outer jacket wedge slot is formed in the bottom surface of the outer jacket through groove, an inner jacket wedge slot is formed in the bottom surface of the inner jacket through groove, and wedges are inserted into the outer jacket wedge slot and the inner jacket wedge slot.

One end of the wedge is provided with a wedge V-shaped gap.

The upper side of the inner jacket 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 on the rail, the passing of the holding claws is not influenced, the butt joint of the rail is not easy to deform or dislocate, the occurrence of derailment accidents is prevented, the wedge can prevent the loosening of the fixed jacket, and the rail web guard plate can increase the strength of the rail web.
