Problems solved by technology

Compared with ordinary manual inspection, this method quantifies the steps that data information needs to rely on manual judgment, but the operation method is basically the same as manual inspection, and the operation efficiency has not been greatly improved; Some hand-push testing equipment will be used for flaw detection and shape and size tolerance testing. However, due to relying on hand-push walking, there are still problems of high labor intensity and low efficiency.
(4) Use auxiliary vehicles for inspection; the workers in the public works section can also use auxiliary special maintenance vehicles to carry out track fastener assembly and patrol inspection. This maintenance method can reduce the physical labor of workers and improve work efficiency. However, due to the need It is completed by manpower and needs to be affected by weather conditions, and maintenance cannot be performed in some bad weather
Use manual tools to tighten, and when the bolt torque is relatively large, you need to use a booster rod, which is labor-intensive; the bolt tightening torque depends entirely on the worker's hand feeling, and the accuracy of the torque value cannot be controlled, and there is a risk of over-torque or miss-hitting; (2) Using fuel Or hydraulic tools, heavy-duty fuel-powered wrench with sustainable power and can be assembled to rail carts; but it is only suitable for vertical rail bolt conditions, and cannot adapt to fishplate conditions. The machine is heavy, noisy, has exhaust gas emissions, and has no data Acquisition, storage and transmission functions; (3) Tighten with the help of electric wrench, still need to rely on workers to operate, can not be fully automated, still cannot avoid some quality problems caused by personnel negligence, and automatic methods inefficient compared to

Abstract

The invention belongs to the technical field of track maintenance, and specifically discloses a track fastener robot automatic tightening system and method. Including rail car, rail car positioning module, fastener and track detection module, servo electric tightening machine module, elbow tightening robot module, communication module, workstation module, management server module, rail car positioning module is used to locate the position information of rail car , the fastener and track detection module is used to detect the crack damage of the rail to be detected and the locking torque of the rail fastener bolt, and the workstation module is used to determine the track to be tightened according to the position information of the rail car and the locking torque value of the rail fastener bolt Fastener bolts, calculate the position information of the track fastener bolts to be tightened, and control the corresponding tightening machine to tighten or replace the track fastener bolts to be tightened according to the orientation of the track fastener bolts. The invention realizes the automatic detection of rail flaw detection, rail fastener state and bolt locking torque, and has high work efficiency and work precision.

Description

technical field [0001] The invention belongs to the technical field of automatic track maintenance, and more specifically relates to a robot automatic tightening system and method for track fasteners. Background technique [0002] The detection methods and main features of the state of track fasteners and the locking torque of sleeper bolts in the former high-speed railway, subway and other construction sections are as follows: (1) Manual inspection, which must be completed within the skylight time. In the dark night, light up with a flashlight, watch through human eyes, and then use a small hammer to tap the fastener screws one by one to check for looseness; due to the lack of fast and effective equipment and methods, misjudgment and misjudgment are easy to occur. The inspection efficiency of fasteners is also relatively low, and it takes a long time to complete the inspection of a section of line. Therefore, in order to realize high-efficiency railway safety inspection an...
