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. In the existing common rail clamping vehicle transportation technology, the adopted rail connection mode is required to perform reaming processing on the rail or weld a steel plate on the steel rail, but if the original rail is used for reconstruction in a coal mine, the steel plate is subjected to reaming processing or welded on the steel rail, the rail laying period is long, the cost is high, and particularly, a tunnel with coal dust or gas cannot be welded at all.

Disclosure of Invention

The invention aims to provide a combined connecting sleeve of a rail butt joint.

The technical scheme includes that the combined connecting sleeve of the rail butt joint comprises a fixing sleeve and a top plate, wherein a rail bottom plate clamping groove is formed in one side of the fixing sleeve, a boss is arranged on the other side of the fixing sleeve, a rail bottom plate clamping opening is formed in the top plate, the top plate is arranged on one side of the boss in the fixing sleeve, a top plate jacking screw hole is formed in the boss, and a top plate jacking screw rod is arranged in the screw hole.

A track jacking screw hole is formed in the bottom of the fixed clamping sleeve, and a track jacking screw rod is arranged on the track jacking screw hole.

A rail waist guard plate is arranged above the rail bottom plate clamping groove of the fixed clamping sleeve.

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 pre-tightening force of the threaded fastener enables the rails to generate pre-pressure and tightly contact with the contact surfaces of the fixed clamping sleeve and the top plate, and the rails can be prevented from loosening and resisting deformation. The track does not need to be reamed or welded with steel plates, so that the track laying workload is reduced, the track laying construction period is shortened, and the track laying cost is reduced.

Detailed Description

As shown in fig. 1, 2 and 3, the combined connecting sleeve for the rail butt joint comprises a fixing sleeve 1 and a top plate 2, wherein one side of the fixing sleeve 1 is provided with a rail bottom plate clamping groove 11, the other side of the fixing sleeve 1 is provided with a boss 12, the top plate 2 is provided with a rail bottom plate bayonet 21, the top plate 2 is arranged on one side of a boss 12 in the fixing sleeve 1, the boss 12 is provided with a top plate jacking screw hole 41, and a top plate jacking screw rod 4 is arranged in the screw hole 41.

A track jacking screw hole 31 is formed at the bottom of the fixed cutting sleeve 1, and a track jacking screw rod 3 is arranged on the track jacking screw hole 31.

A waist guard plate 13 is arranged above the clamping groove 11 of the rail bottom plate of the fixed cutting sleeve 1.

As shown in fig. 4, 5 and 6, when the device is installed and used, a bottom plate on one side of the rail 5 is sleeved in the rail bottom plate clamping groove 11 at the joint of the rail 5, the rail bottom plate bayonet 21 of the top plate 2 is clamped on the bottom plate on the other side of the rail 5, and the rail tightening screw 3 and the top plate tightening screw 4 are screwed tightly; the rail web guard plate 13 is propped against the inclined plane of the head part of the rail 5 and the inclined plane of the foot plate, so that pre-pressure is generated between the rail and each contact surface of the fixed cutting sleeve and the top plate and the rail is tightly contacted.

As shown in fig. 7 and 8, a rail butt joint combination connecting sleeve is installed at the joint of the rail 5, and the rail tightening screw 3 and the top plate tightening screw 4 are tightened to prevent the joint of the rail 5 from loosening; when the holding clamp 7 of the braking device of the shuttle car 6 brakes, the holding clamp 7 is held on the head inclined plane of the track 5 from the outer side of the track 5, and the track butt joint combined connecting sleeve does not influence the passing of the holding clamp 7.
