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 connecting and fixing clamp.

The technical scheme of the invention is that the rail butt joint is connected with the fixing clip, a bayonet which is matched with the cross section of the rail is arranged in the fixing clip, and the rail is nested in the bayonet.

Iron sand cement concrete is filled in the gap between the bayonet of the fixing clip and the track.

The bottom of the bayonet is provided with a vent hole.

The inner bottom surface of the bayonet of the fixing clip is provided with a wedge groove, and a wedge is inserted into the wedge groove.

The inner bottom surface of the bayonet of the fixing clip is provided with a screw hole, and a screw rod is arranged in the screw hole.

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, and the fastening device is filled in the gap between the bayonet of the fixing clip and the rails, so that the looseness of the rails can be prevented.

Detailed Description

As shown in fig. 1, 2, 3, 4, 5 and 6, a rail butt joint is connected with a fixing card, wherein a bayonet 12 corresponding to the section of a rail 2 is arranged in the fixing card 1, and the rail 2 is nested in the bayonet 3.

Iron sand cement concrete 3 is filled in the gap between the bayonet 3 of the fixing clip 1 and the track 2.

The bottom of the bayonet 3 is provided with a vent hole 13.

As shown in fig. 7, 8, 9, 10 and 11, a rail butt joint is connected with a fixing clip, wherein a bayonet 12 corresponding to the section of a rail 2 is arranged in a fixing clip 1, and the rail 2 is nested in the bayonet 3. A wedge groove 14 is formed on the inner bottom surface of the fixing clip 1, and a pair of wedges 15 are inserted into the wedge groove 14.

As shown in fig. 12 and 13, a rail butt joint is connected with a fixing clip, wherein a bayonet 12 corresponding to the section of a rail 2 is arranged in a fixing clip 1, and the rail 2 is nested in a bayonet 3. A screw hole 33 is formed in the inner bottom surface of the bayonet 12 of the fixing card 1, and a screw 34 is provided in the screw hole 33.

As shown in fig. 14 and 15, the rail 2 is installed on the sleeper 4, the rail butt joint connecting fixing clip is installed at the butt joint of the rail 2, the rail 2 is nested into the bayonet 12 from one end of the fixing clip 1, and the gap between the bayonet 3 of the fixing clip 1 and the rail 2 is filled with iron sand cement concrete 3 to prevent the rail from loosening; the braking device of the shuttle car 5 comprises holding clamps 6 and brake levers 7, when braking is conducted, the holding clamps 6 are held on the rail web of the rail 2 from two sides of the rail 2, the brake levers 7 apply braking pressure from the tread of the steel rail 2 to conduct friction braking, and the rail butt joint is connected with the fixing clamp so that the passing of the holding clamps 6 is not affected.
