Device for loosening and tightening railway steel rail fastener bolts

Abstract

The invention relates to railway engineering machinery, particularly relates to a device for quickly loosening and tightening railway steel rail fastener bolts and an operation method of the device, and the device is applied to the field of railway engineering and equipment maintenance. The device comprises a base support 4, and is characterized in that the base support 4 is connected with a driven walking mechanism 1 and a driving walking mechanism 10; a walking distance detection device 2 is connected with the driven walking mechanism 1, and a three-in-one speed reducer 9 is connected with the driving walking mechanism 10 through a locking disc; a bolt position detection device 3 is connected with the base support 4 and is used for detecting the relative position of each group of fastener bolts; a cross sliding guide rail and servo driving device 7 is arranged on the upper surface of the base support 4, an electric wrench 6 is arranged on the cross sliding guide rail and servo driving device 7, a diesel generator 5 is arranged on one side of the base support 4 to serve as a power mechanism of the whole device, and a control box and a control panel 8 are arranged on the other sideof the base support 4, and are used for controlling the whole device to automatically loosen and tighten railway steel rail fastener bolts. According to the device for loosening and tightening the railway steel rail fastener bolts, manual assistance is not needed, tightening and loosening operation of the railway steel rail fastener bolts can be conducted in a full-automatic mode, an existing working mode that manpower is matched with a mechanical wrench can be replaced, a large amount of manpower is saved, the working efficiency is greatly improved, and integrated construction is conducted in cooperation with a rail changing vehicle.

Description

technical field [0001] The invention relates to a railway engineering machine, in particular to a device for quickly loosening rail fastening bolts used in the field of railway engineering and equipment maintenance. Background technique [0002] The rails on the railway line need to be replaced after being used for a certain period of time due to wear and tear, and the rail fasteners need to be disassembled when the rails are replaced. Among them, loosening and tightening fastener bolts is a heavy labor in the daily maintenance and repair of the line, and with the continuous increase of train running speed and train running density, the requirements for the pressure of line fasteners are also increasing. Not only does it require tightening, but it also requires consistent torque, and at the same time, the sunroof repair time that can be provided is also getting shorter and shorter. [0003] At present, the loosening and tightening of fastener bolts are all carried out manua...

AI Technical Summary

Problems solved by technology

[0003] At present, the loosening and tightening of fastener bolts are all carried out manually with mechanical wrench, which requires a large number of workers and takes up a lot of working time in a skylight period, which is not only labor-intensive, but also low-efficiency

At the same time, when dismantling the remaining fastener bolts of the old rail, the staff must cross-operate with the rail changing vehicle at the same time, which poses a great safety hazard
