Abstract

The invention relates to the field of cantilever tunneling machines, in particular to a system and method for detecting the abrasion state of cutting teeth of a cantilever tunneling machine. The system comprises a main controller, a vibration sensor, a current sensor, an infrared thermal imager and a display output mechanism; the vibration sensor and the current sensor are both fixedly arranged ona cutting arm of the cantilever tunneling machine, and the current sensor is electrically connected with a cutting motor of the cantilever tunneling machine; the infrared thermal imager is mounted onthe upper section of the cutting arm of the cantilever tunneling machine; and the display output mechanism is electrically connected with the main controller and used for outputting a detection result to an operator in a figure and/or sound form. According to the system and method for detecting the abrasion state of the cutting teeth of the cantilever tunneling machine, abrasion of the cutting teeth can be found in time, the situation that abrasion of the adjacent cutting teeth is intensified and consequently, the cutting teeth lose efficacy is avoided, cutting tooth abrasion degree information can be output, the tunneling efficiency is improved, actual cutting operation of a construction site is adopted to collect characteristic data of cutting tooth abrasion detection, the authenticityof the characteristic data is improved, and the detection pre-judgment result is ensured.

Description

technical field [0001] The invention relates to the field of cantilever roadheaders, in particular to a system and method for detecting the wear state of a cantilever roadheader pick. Background technique [0002] As an efficient and flexible tunneling equipment, the cantilever roadheader has been widely used in roadway, tunnel excavation and ore mining. Picks are consumables in the excavation of the roadheader. During the excavation, the operator needs to pay attention to the wear status of the picks in real time. When partial wear of some picks occurs, the work efficiency will be reduced and the loss of other picks will be accelerated, which will seriously damage the picks. Adapter and cutting head body. This situation requires long-term welding repairs on site, which affects the start-up rate. In the existing scheme CN109113740A-infrared temperature sensing feedback wear failure pick patent, a temperature measuring device is installed on each pick and the temperature si...
