Hydraulic lifting platform guide rail adjusting structure used for rail traffic maintenance

Abstract

A hydraulic lifting platform guide rail adjusting structure used for rail traffic maintenance comprises a lateral moving platform, rolling wheel shafts are installed on the lateral moving platform, the rolling wheel shafts are sleeved with rolling wheels in a circumferential rotating manner, the rolling wheels and guide rail grooves are clamped and assembled in a rolling manner, the guide rail grooves are arranged on the two sides of a guide rail, and the guide rail is installed on a guide rail seat. A guide rail shaft block is installed at the bottom of the guide rail seat and is arranged ona guide rail rotating shaft in a sleeving and circumferential rotating manner, and the two ends of the guide rail rotating shaft are assembled with a rack of a hydraulic lifting platform. Through guide rail seat grooves are formed in the guide rail seat, adjusting swing rods penetrate through the guide rail seat grooves, and the adjusting swing rods and the guide rail seat grooves are assembled ina relative rotating manner. The adjusting swing rods are hinged to adjusting shaft plates through swing rod rotating shafts, the adjusting swing rods intersect with push plates after penetrating through holding grooves in a holding plate, the push plates are assembled with racks and one ends of push rods, and the racks are in engaged transmission with gears. The gears are arranged on screw rods in a sleeving manner, the screw rods can drive a lifting bottom plate to move up and down, and supporting rods are installed on the lifting bottom plate and are directly or indirectly pressed with thebottom of the guide rail seat.

Description

technical field [0001] The invention relates to the technology of a hydraulic lifting platform for track maintenance, in particular to a guide rail adjustment structure of a hydraulic lifting platform used for rail transit maintenance. Background technique [0002] In the maintenance of rail trains, it is generally necessary to use a hydraulic lifting platform to weigh heavy equipment such as bogies and batteries, and then transport them to the station for maintenance. Generally, guide rails are installed on the hydraulic lifting platform, and a side shifting platform is installed on the guide rails, so as to facilitate the adjustment of the position of the equipment. However, because the weighing of the side shifting platform is not in the center, as well as assembly errors and wear during use, etc., there will be an inclination between the guide rail and the side shifting platform, which makes the difference between the guide rail and the side shifting platform during use....

AI Technical Summary

Problems solved by technology

However, because the weighing of the side shifting platform is not in the center, as well as assembly errors and wear during use, etc., there will be an inclination between the guide rail and the side shifting platform, which makes the difference between the guide rail and the side shifting platform during use. Shaking, there is a greater safety hazard
