Rail bolt type telescopic adjustable anti-climbing support

Abstract

The invention relates to a rail bolt type telescopic adjustable anti-climbing support, which is characterized in that bolt groovesare formed on the inner wall of two sides of the anti-climbing box, apressure spring is fixedly connected witheach bolt groove, one end of the trapezoidal bolt is inserted into the bolt groove and is connected with the pressure spring; the telescopic frame of astressedtop plate is inserted into acavity, the bottom of the telescopic frame of the stressed top plate is provided with a straight rack, two F-shaped sliding blocks and a reset gear are arranged in the middle, the outer vertical edge and the inner transverse edge of the F-shaped sliding block are respectively a one-way saw tooth and a reset straight rack, the reset gear is meshed with the reset straightrack of the F-shaped sliding block, and the outer end of the trapezoidal bolt on the wall of the anti-climbing box is meshed with the one-way saw tooth of the F-shaped sliding block to form a self-lock; the auxiliary gear at the bottom of the anti-climbing box is meshed with the straight rack at the bottom of the stressed top plate telescopic frame. The rail bolt type telescopic adjustable anti-climbing support can adjust the size of anti-climbing supportthrough the meshing between the trapezoidal bolt and the one-way saw tooth, and has the advantages of good universality, strong structural stress resistance, free expansion and adjustment, convenient maintenance and replacement and the like.

Description

technical field [0001] The invention relates to railway traffic equipment, in particular to a track bolt type telescopic adjustable anti-climbing brace. Background technique [0002] When the train runs on the main line of the section of the double-track railway, the direction of the heavy vehicle of the single-track railway, the long downhill slope, the small radius curve, and the braking range when entering the station, the longitudinal force acting on the rail is often generated, making the rail For longitudinal movement, and sometimes even drive the sleeper to move together, this longitudinal movement is called "crawling". Line crawling often causes consequences such as uneven rail gaps and skewed sleepers, which is very destructive to the line, and even causes a small rise in the track, endangering driving safety. Therefore, effective measures must be taken to prevent line crawling, the purpose of which is to strengthen the overall strength of the track structure, incr...

Problems solved by technology

However, there are a variety of sleeper spacing standards in our country, among which the most used are 1680, 1760 and 1840 sleeper spacing per kilometer, so the existing anti-climbing braces cannot be used in all kinds of sleeper spacing. On the one hand, certain errors will inevitably occur when laying sleepers on site, which will cause the actual spacing between sleepers to be inconsistent with the size of the prefabricated anti-climbing braces, resulting in the failure of the anti-climbing braces to be installed or the installation.
