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 seat.

The technical scheme includes that the rail butt joint fixing seat comprises a base, wherein an installation groove is formed in the base, and a rail is installed in the installation groove through an outer pressing plate and an inner pressing plate.

An outer pressing plate mounting screw hole and an inner pressing plate mounting screw hole are formed in the bottom of the mounting groove, an outer pressing plate fixing bolt is connected in the outer pressing plate mounting screw hole, and an inner pressing plate fixing bolt is connected in the inner pressing plate mounting screw hole.

An outer pressing plate pressing screw hole is formed in the groove wall on the outer side of the mounting groove, an outer pressing plate pressing bolt is installed in the outer pressing plate pressing screw hole, an inner pressing plate pressing screw hole is formed in the groove wall on the inner side of the mounting groove, and an inner pressing plate pressing bolt is installed in the inner pressing plate pressing screw hole.

The upper part of the inner pressure plate is provided with a 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 claws is not influenced, the butt joint of the rail is not easy to deform and dislocate, the occurrence of derailment accidents is prevented, and the rail web guard plate can increase the strength of the rail web.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, and fig. 7, a rail butt joint fixing seat includes a base 1, and is characterized in that: there is a mounting groove 11 on the base 1, and the rail 2 is mounted in the mounting groove 11 through the outer pressing plate 3 and the inner pressing plate 4.

An outer pressing plate mounting screw hole 12 and an inner pressing plate mounting screw hole 14 are formed in the bottom of the mounting groove 11, an outer pressing plate fixing bolt 31 is connected to the outer pressing plate mounting screw hole 12, and an inner pressing plate fixing bolt 41 is connected to the inner pressing plate mounting screw hole 14.

An outer pressing plate pressing screw hole 13 is formed in the outer side groove wall of the mounting groove 11, an outer pressing plate pressing bolt 32 is installed in the outer pressing plate pressing screw hole 13, an inner pressing plate pressing screw hole 15 is formed in the inner side groove wall of the mounting groove 11, and an inner pressing plate pressing bolt 42 is installed in the inner pressing plate pressing screw hole 15.

The upper part of the inner pressure plate 4 is provided with a rail waist guard plate 43.

As shown in fig. 8 and 9, the rail 2 is installed on the sleeper 5, the rail butt joint fixing seat is installed at the butt joint of the rail 2, the braking device of the shuttle car 6 comprises an embracing claw 7 and a braking rod 8, when braking is carried out, the embracing claw 7 embraces the rail web of the rail 2 from two sides of the rail 2, the braking rod 8 exerts braking pressure from the tread of the steel rail 2 to carry out friction braking, and the rail butt joint fixing seat does not influence the passing of the embracing claw 7.
