Wear detection system

Abstract

A wear detection system comprises a data acquisition unit and a data processing unit, the data acquisition unit comprises a radio frequency reader-writer and a plurality of radio frequency tags with unique identity information, the radio frequency tags are arranged at different wear areas of a to-be-detected device, and when a certain wear area is worn, the radio frequency tag arranged in the wear area is damaged or falls off; when the to-be-detected device needs to be subjected to wear detection, the radio frequency reader-writer sends an inquiry signal to the radio frequency tag, and reads a response signal containing identity information returned by the undamaged radio frequency tag which is left on the to-be-detected device after receiving the inquiry signal; the data processing unit stores identity information of all the radio frequency tags and the arrangement position of each radio frequency tag on the to-be-detected device, the damage and falling conditions of the radio frequency tags in different wear areas are counted and analyzed according to the identity information read by the radio frequency reader-writer, and then the abrasion condition of the to-be-detected device is judged. The detection system is high in detection efficiency, high in precision and low in cost.

Description

technical field [0001] The invention relates to a wear detection system, which can be applied to the wear detection of a device with a relatively large wear limit value. Background technique [0002] With the widespread use of tunnel boring machines in engineering, it has gradually been found that tool wear has become a key issue affecting the quality, progress and safety of the project during construction. First, a single knife was damaged during work. The tool in the direction is subjected to an eccentric load, which causes the wear of other tools to intensify, which in turn leads to the overall eccentric load of the cutter head, and finally causes the cracking and disintegration of the entire cutter head. At present, the hob wear mainly adopts the method of opening the cabin for inspection, that is, after the machine is shut down, the cutters are manually entered into the cabin to check one by one. In unstable formations, the ground needs to be strengthened or under press...

[0002] With the widespread use of tunnel boring machines in engineering, it has gradually been found that tool wear has become a key issue affecting the quality, progress and safety of the project during construction. First, a single knife was damaged during work. The tool in the direction is subjected to an eccentric load, which intensifies the wear of other tools, which leads to the overall eccentric load of the cutter head, and finally causes the cracking and disintegration of the entire cutter head

At present, the hob wear mainly adopts the method of opening the cabin for inspection, that is, after the machine is shut down, the cutters are manually entered into the cabin to check one by one. In unstable formations, the ground needs to be strengthened or under pressure before the cabin is opened for inspection. , although opening the cabin inspection is direct and effective, but there is a high risk, it is likely to cause ground collapse and other accidents due to the instability of the working surface, and the detection efficiency is low
