Description

Fixed cutting sleeve for butt joint of rail

Technical Field

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

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.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fixed cutting ferrule of track butt joint.

The technical scheme of the utility model, a fixed cutting ferrule of track butt joint, including fixed pothook, it has the hook groove that suits with the track rail end to open on fixed pothook, and it has the pothook bolt hole to open on fixed pothook, has the pothook briquetting on fixed pothook opposite face, opens at the pothook briquetting and has the slide wedge groove, has the slide wedge at the slide wedge groove, has the fastener at the slide wedge downside.

The hook top of the fixed hook is provided with a rail waist guard plate.

The utility model discloses there is following technological effect, and it is fixed to reinforce track butt joint department, when transportation equipment departments such as mine car or shuttle were stopped, firstly does not shadow the passing through of embracing the claw, secondly track butt joint department is difficult to warp the dislocation, prevents the emergence of derailment accident, and the slide wedge can prevent that the pothook briquetting is not hard up, and the rail web backplate can increase the intensity of rail web.
