Problems solved by technology

[0005] However, in the prior art, the rail head rollers are installed on the outside of the guide seat. If the rails are upturned or drooped during operation, the vertical position of the rails between the rail head rollers must change.
At this time, due to the limited length of the rail head roller, it is very likely that the rail will break away from the restraint of the clampin

Abstract

The invention discloses a steel rail takeup and putdown device which comprises a positioning module and a steel rail clamping module. The positioning module comprises a guide seat, a hanging rack assembly and a vertical oil cylinder. The steel rail clamping module comprises a slide block, wherein a long clamping wheel and a short clamping wheel mutually and oppositely arranged in the length direction of the guide seat and movably clamp a steel rail, rail head leaning wheels located at the rear portion of the long clamping wheel and the rear portion of the short clamping wheel, mutually and oppositely arranged in the length direction of the guide seat and always fixing and clamping a rail head of the steel rail and a rail pressing wheel arranged at the upper portion between the long clamping wheel and the short clamping wheel and always exerting downward pressure on the rail face of the steel rail are further arranged inside the slide block. The steel rail takeup and putdown device can clamp and move the steel rail according to rail change demand, effectively controls the acting force of the steel rail, enables the steel rail to be smoothly arranged into a rail bearing groove and is suitable for railway rail changing operation.

Description

technical field [0001] The invention relates to the field of railway engineering, in particular to a rail retracting and unwinding device applied to a railway rapid rail changing operation vehicle. 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. Especially when a new rail enters the rail bearing groove, it is necessary to make the rail move according to the operation requirements 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.
