Abstract

The utility model discloses a swivel nut formula track butt joint connecting plate has track butt joint bolt hole in orbital butt joint department, is equipped with the swivel nut in the track butt joint bolt hole of orbital butt joint department, the outside of swivel nut have the flange, be equipped with the connecting plate in orbital butt joint department inboard rail waist department, it has the connecting plate bolt hole to open on the connecting plate, the bolt passes in the swivel nut of connecting plate bolt hole connection in track butt joint bolt hole. The utility model discloses there is following technological effect, the swivel nut sinks in track butt joint screw, and the flange is pasted on track outside web of rail, does not influence embracing the passing through of claw, and the connecting plate prevents to become flexible from inboard trapped orbit, can increase the intensity of web of rail, strengthens track butt joint department fixed, and when transportation equipment such as mine car or shuttle when the track braking, track butt joint department is difficult to the track and warp the dislocation, prevents the emergence of derailment accident.

Description

Threaded sleeve type track butt joint connecting plate

Technical Field

The utility model belongs to the supporting facility in supplementary transportation's such as mine mining's underground or aboveground mine car and shuttle car in mineral exploitation track, mainly used track butt joint department is fixed.

Background

The rails of the rail transport equipment for mining mostly adopt GB11264 rails or YB5055 rails, and the connection mode at the butt joint of the two rails 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 on-vehicle emergency braking mode that transportation equipment such as mine car, shuttle car of mine transportation adopted is through embracing the claw and carrying out the armful rail braking in track both sides, because splint, bolt, the nut that two orbital butt joint departments are connected can hinder and embrace the claw and pass through, can not carry out hook rail braking or card rail operation to track both sides downside, cause the brake force reliability low, bring the potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a swivel nut formula track butt joint connecting plate.

The technical scheme of the utility model, a swivel nut formula track butt joint connecting plate, there is the track butt joint bolt hole at orbital butt joint department, is equipped with the swivel nut in the track butt joint bolt hole of orbital butt joint department, the outside of swivel nut have the flange, be equipped with the connecting plate in inboard rail web department of orbital butt joint department, it has the connecting plate bolt hole to open on the connecting plate, the bolt passes in the swivel nut of connecting plate bolt hole connection in track butt joint bolt hole.

The utility model discloses there is following technological effect, the swivel nut sinks in track butt joint screw, and the flange is pasted on track outside web of rail, does not influence embracing the passing through of claw, and the connecting plate prevents to become flexible from inboard trapped orbit, can increase the intensity of web of rail, strengthens track butt joint department fixed, and when transportation equipment such as mine car or shuttle when the track braking, track butt joint department is difficult to the track and warp the dislocation, prevents the emergence of derailment accident.
