Detection device and detection method for wear loss of shield machine cutter

Abstract

The invention discloses a detection device and a detection method for the wear loss of a cutter of a shield machine. A detection probe which is connected with an input end of a detector through a data line is arranged in the peripheral foregoing teeth-cutter of the shield machine, wherein the detector is connected with a programmable logic controller (PLC) control system of the shield machine through a signal output device; and the PLC control system of the shield machine is connected with a touch screen and communicates with the touch screen. The detection device has the advantages that the wear loss of the peripheral teeth-cutter is detected through detecting the height of an alloy strip on the peripheral foregoing teeth-cutter of the shield machine, so the defects in a hydraulic limit type detection manner that an alarm can be given only when the cutter is worn to a certain height is overcome, and thereby the detection device can continuously display measured data in time; through welding the peripheral foregoing teeth-cutter on a cutter holder, the problem that a welded type cutter is difficult to detect is solved; meanwhile, data detected through utilizing a conductive slide wire ring can be displayed and recorded in time in a touched manner in an operating room, so the detection device is more convenient to use; and besides, the detection device has high measurement accuracy, great real time performance and high reliability.

Description

technical field [0001] The invention specifically relates to a detection device and detection method for the amount of tool wear of a shield machine, which is used in the industry of the shield machine to detect the amount of wear of the leading tooth cutter on the outer periphery of the cutter head. Background technique [0002] At present, with the continuous advancement of China's urbanization process, the shield tunneling method has been widely used in domestic subway construction, and with the advancement of this process, the development of shield tunneling has shown several major trends of large cross-section, large depth, and long distance . These major trends have put forward higher requirements on the cutter head and cutting tools of the shield machine. Timely mastering the wear pattern and amount of cutting tools plays a decisive role in setting reasonable tunneling parameters and replacing cutting tools in a planned way. [0003] In Beijing, Shenyang and other s...

AI Technical Summary

Problems solved by technology

Once the surrounding advanced tooth cutter wears out, it will be difficult to guarantee the cutting diameter of the cutter head, which will bring great difficulties to the advancement of the shield.

Because of the particularity of the position of the peripheral advanced tooth cutter, the advanced tooth cutter is mostly assembled in the form of welding, which makes it more difficult to equip the electronic components in the tooth cutter. Therefore, it is a reasonable method to determine the wear amount of the peripheral advanced tooth cutter. Issues that need to be resolved
