Rail butt joint clamping base

Abstract

The invention discloses a rail butt joint clamping base. The rail butt joint clamping base comprises a rail clamping base body, a pair of rail outer side pressing blocks and a pair of inner side railweb top blocks. A pair of outer side pressing block waist-shaped bolt holes is formed in the rail bottom side on the outer side of a rail on the rail clamping base body. Outer side pressing block boltholes are formed in the rail outer side pressing blocks respectively. An outer side pressing block fastener penetrates through one outer side pressing block bolt hole and the corresponding outer sidepressing block waist-shaped bolt hole to fasten the corresponding rail outer side pressing block. An ejector rod is arranged on each inner side rail web top block. The ejector rods of the pair of inner side top blocks are connected through a left and right threaded nut. The rail butt joint clamping base has the following technical effects that because fixation on a rail butt joint is strengthened, when a mine car or a shuttle car or other conveying equipment brakes on the rail, on one hand, passage of holding claws is not affected, and on the other hand, rail deformation or dislocation is notprone to happening to the rail butt joint, and then derailment accidents are avoided; and because the ejector rods are connected to the top blocks, and the ejector rods of the pair of rail inner sidetop blocks are connected through the left and right threaded nut, the rail outer side clamping base body is tightly clamped from the inner sides to prevent the rail outer side clamping base body fromgetting loose, and the strength of the rail webs can be improved.

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 purpose of the present invention is to provide...
