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

Embodiment Construction

[0015] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 A track butt joint fixing plate is shown, including a bottom plate 1 and a pressure block 2. On the bottom plate 1, there are bolt holes 11 on both sides of the bottom of the track 4, and there are firm parts 3 at the bottom of the pressure block 2. Two pairs of pressure blocks 2 are relatively pressed on the rail bottoms on both ends of the butt joint of the track 4 respectively, and are connected to the bottom plate 1 through the firm piece 3 .

[0016] Such as Figure 8 , Figure 9 As shown, the track 4 is installed on the sleepers 5, the track butt joint fixing plate is installed on the bottom surface of the rail bottom at the butt joint of the track 5, and two pairs of pressure blocks 2 are respectively pressed against the rails on both ends of the butt joint of the track 4. On the bottom, it is connected on the base plate 1 by a solid piece, and the braking device of the shuttle car...

Abstract

The invention discloses a rail butt joint fixing plate which comprises a bottom plate 1 and pressing blocks, bolt holes are formed in the two sides, opposite to the rail bottom of a rail, of the bottom plate, fastening pieces are arranged at the bottoms of the pressing blocks, and the two pairs of pressing blocks are oppositely pressed on the rail bottoms on the two sides of the two ends of a railbutt joint respectively and connected to the bottom plate through the fastening pieces. The fixing plate has the following technical effects that fixation of the rail butt joint is strengthened, andwhen transportation equipment such as a mine car or a shuttle car is braked at the rail butt joint, on one hand, passing of the holding claws is not affected, and on the other hand, the rail butt joint is not prone to deformation and dislocation, and derailing accidents are prevented.

Description

technical field [0001] The invention belongs to track supporting facilities of transportation equipment such as underground or above mine cars and shuttle cars for mineral mining, and is mainly used for fixing the butt joints of tracks. 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 pro...
