Railway track maintenance machine based on cooperative working mode of sub-machine and mother machine

Abstract

The invention discloses a railway track maintenance machine based on the collaborative operation mode of a mother machine and a son machine. The maintenance machine comprises a host computer, the mother machine and the son machine. The mother machine is provided with an unevenness detection module, a defect detection module and a bolt looseness detection module. The son machine is provided with a bolt screwing device, an oiling device, a grinding machine and a back testing device. The unevenness detection module and the defect detection module are respectively connected with the host computer. The host computer is used for controlling the screwing device, the oiling device, the grinding machine and the back testing device. The device is relatively small in size, high in integration, automation and intelligence degrees, and relatively high in efficiency. Manpower is saved, the traditional working mode of maintenance separation is changed, collaborative operation of detection and repairing of railway routine maintenance is realized, daily conservation costs are reduced, the working efficiency of conservation is improved, and the like.

Description

technical field [0001] The invention relates to maintenance equipment for railway tracks, in particular to a railway track bolt screwing device. Background technique [0002] With the rapid development of my country's economy, the frequency and intensity of railway transportation continue to increase, and the requirements for daily maintenance of railways continue to increase. The existing detection methods are mostly manual detection or large-scale rail inspection vehicle detection. For sections with large mileage, manual inspection needs to be carried out in sections, with heavy workload, difficult working conditions, low efficiency and high risk. During the detection process, workers mainly rely on experience or use specific small instruments for detection, which has low detection accuracy and is prone to missed detection. The existing rail inspection vehicles can quickly inspect the rails, and can feed back the inspection data to the public works department to provide ...

AI Technical Summary

Problems solved by technology

In terms of maintenance, foreign rail grinding technology has been very mature, which can better eliminate the wavy wear of rails, effectively control rail spalling and other diseases, greatly improve the service life of rails, and generate huge economic benefits. However, detection and The combination of repairs has not been done very well

However, the existing rail maintenance work in our country has the following disadvantages: (1) The maintenance mode is inefficient: the existing maintenance vehicle conducts inspections twice a month, and the inspection results are fed back to the public works section, and maintenance workers carry out maintenance. From the discovery of defects to The cycle of eliminating defects is long, the efficiency is low, and the degree of defect deterioration is deep

(2) Low degree of automation of maintenance machines: the existing small maintenance machines have a single function and are all manually operated, with heavy workload, low maintenance accuracy and high risk

(3) The cost of rail inspection vehicles is high, and the inspection frequency is low: the existing large-scale rail inspection vehicles are expensive, and the inspection frequency is 2 times / month, and defects cannot be detected in time

(4) Statistical analysis of testing data at this stage cannot guide maintenance work well
