Steel rail collecting and placing device

Abstract

The invention discloses a steel rail collecting and placing device. The steel rail collecting and placing device comprises a positioning assembly and a steel rail clamping assembly; the positioning assembly comprises a guiding base, a lifting frame assembly and a perpendicular oil cylinder; the steel rail clamping assembly comprises first sliding blocks and second sliding blocks which are arranged on lower portions at two ends of a guide base in pairs and a first transverse oil cylinder and a second transverse oil cylinder; a positioning plate is arranged on the lifting frame assembly; the guide base perpendicularly moves along the positioning plate under pushing of the perpendicular oil cylinder; combination bodies of the first sliding blocks and the second sliding blocks transversely move along the length direction of the guide base under pushing of the first transverse oil cylinder; the second sliding blocks transversely move relative to the first sliding blocks under pushing of the second transverse oil cylinder. The steel rail collecting and placing device can conveniently and safely clamp and move the steel rail according to the rail replacement requirement, effectively controls the acting force for clamping the steel rail and well adapts to the railway rail change requirement.

Description

technical field [0001] The invention relates to a railway engineering machine, in particular to a rail retracting and unwinding device applied to a rapid rail changing operation vehicle in the field of railway engineering and equipment maintenance. Background technique [0002] Rails are often clamped during railway construction operations, such as changing rails, laying rails, and changing pillows. During the above operations, it is necessary to move the rails according to the requirements of the operation and to control the resulting force. Under various operating conditions, the difference between the rail clamping surface and the supporting surface of the railway construction machinery will have different effects on the construction work. [0003] In patents CN101718067A, CN2263610Y, CN2871617, CN2510526Y, and CN1152169C, different types of track replacement machines suitable for different purposes are disclosed. The method adopted is generally to place the new rail next...

AI Technical Summary

Problems solved by technology

as attached Figure 4 , 6 As shown in and 7, in the prior art, the cylindrical rollers on the second slider and the first slider, the rail top rollers and the rail bottom rollers are not in the same vertical plane, and the distance is relatively large, so the position of the rail cannot be well controlled

At the same time, since the cylindrical rollers, rail top rollers and rail bottom rollers are not in the same vertical plane, when the rail clamping device in the prior art clamps the rail, it is very easy to cause deformation due to the bending of the rail
