Problems solved by technology

The vehicle-mounted emergency braking method adopted by mining vehicles, shuttle cars and other transportation equipment is to hook the claws on the lower side of the rail head, and the brake lever is pressed from the track tread to perform rail-holding braking. The splints, bolts and nuts connected at the butt joint will hinder the passage of the claws, affect the braking, and cause safety accidents

Abstract

The invention discloses a rail butt joint fixing device. A sleeper is arranged at a rail butt joint; positioning grooves are formed in the two sides of the rail on the sleeper. A rail fixing pressingplate screw hole is formed in one side of the positioning groove; a positioning block is arranged on one side of the track fixing pressing plate, the positioning block of the track fixing pressing plate is inserted into the positioning groove, the track fixing pressing plate is pressed on the base on the two sides of the joint of the track, the track fixing pressing plate is fixed through a trackfixing pressing plate bolt, and the track fixing pressing plate bolt is connected into a track fixing pressing plate screw hole of the sleeper. The rail butt joint has the following technical effectsthat fixation of the rail butt joint is strengthened, when a mine car or a shuttle car brakes at the rail butt joint, passing of the holding claws is not affected, rail deformation and dislocation arenot likely to happen at the rail butt joint, and derailment accidents are prevented.

Description

technical field [0001] The invention belongs to auxiliary transportation track supporting facilities such as underground or above-ground mine cars and shuttle cars for mineral mining, and is mainly used for fixing rail butt joints. Background technique [0002] The rails of underground or above-ground mine cars and shuttle cars and other transportation equipment for mineral mining mostly use GB11264 rails or YB5055 rails. Both sides of the rail waist are clamped by splints, bolts and nuts. The vehicle-mounted emergency braking method adopted by mining vehicles, shuttle cars and other transportation equipment is to hook the claws on the lower side of the rail head, and the brake lever is pressed from the track tread to perform rail-holding braking. The splints, bolts and nuts connected at the butt joint will hinder the passage of the claws, affect the braking, and cause safety accidents. Contents of the invention [0003] The object of the present invention is to provide ...
