Track gear type telescopic and adjustable anti-climbing support

Abstract

Provided is a track gear type telescopic and adjustable anti-climbing support. The track gear type telescopic and adjustable anti-climbing support is characterized in that four symmetrically distributed coaxial gears are mounted in an anti-climbing box; the coaxial gears are divided into lower coarse teeth and upper fine teeth; one end of a stressed roof is inserted into a sliding cavity of the anti-climbing box, and both sides of the stressed roof are provided with racks; the racks on each side are meshed with the lower coarse teeth of the two coaxial gear; a giant rack is arranged on the upper portion of a telescopic area of the stressed roof; an adjusting bolt on the anti-climbing box is meshed with the giant rack through an auxiliary gear; locking arc pins with active ends meshed withthe upper fine teeth of the coaxial gears are disposed on both legs of a holder; reset bolts arranged on both sides of the anti-climbing box are connected with the holder. With the track gear type telescopic and adjustable anti-climbing support, the purpose of adjusting size of the anti-climbing support is achieved through the working principle of an one-way gear, mutual engagement between gears and the application of an one-way clutch. Furthermore, the track gear type telescopic and adjustable anti-climbing support has various advantages such as good versatility, strong structural stress bearing capability, freely telescopic adjustment, and convenient maintenance and replacement.

Description

technical field [0001] The invention relates to railway traffic equipment, in particular to a rail gear 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, incre...

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.
