Special dismounting device for bullet train track bridge III-type elastic strips

Abstract

The invention relates to the technical field of railway track mechanical equipment, and discloses a special dismounting device for bullet train track bridge III-type elastic strips, which comprises a main body. A bottom plate is fixedly mounted in the middle of the main body, rolling shafts are movably connected to the left side and the right side of the bottom of the bottom plate, and pulleys are arranged at the front ends and the rear ends of the rolling shafts; the left side of the upper surface of the bottom plate is fixedly connected with a storage box, and driving devices are arranged above and below the upper surface of the bottom plate. According to the special dismounting device for the bullet train track bridge III-type elastic strip, an air cylinder in a driving device drives a piston rod to rotate in a fixed block, and the piston rod drives a sliding block to slide left and right back and forth in a sliding groove; and the first rotating ball, the second rotating ball and the third rotating ball drive the first connecting rod, the bent rod and the second connecting rod to move, then the hook is driven to do circular motion, the lower bent position of the fastener is pulled, the fastener is disassembled, and therefore the effect that workers do not need to disassemble the fastener by themselves can be achieved.

Description

technical field [0001] The invention relates to the technical field of railway track machinery and equipment, in particular to a special dismantling device for type III elastic strips of a rail bridge of a motor train. Background technique [0002] Rail fasteners are the parts on the track used to connect the rails and sleepers (or other types of under-rail foundations), also known as intermediate connecting parts. Its function is to fix the rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. With the rapid development of China's economy, the scale and technical level of China's railway and urban rail transit construction have been continuously improved. The performance requirements of locomotives, locomotives, rails, rail fasteners, etc. are getting higher and higher, and the rail transit system produces vibration shocks due to the impact of wheels and rails during driving. The performance requirem...
