Portable intelligent detector for hobbing cutter and processing method for hobbing cutter wear data

Abstract

The invention provides a portable intelligent detector for a hobbing cutter and a processing method for hobbing cutter wear data. The portable intelligent detector for the hobbing cutter comprises a casing, wherein a first sliding rail and an electric servo sliding rail are arranged in the casing; a first support leg and a second support leg which are used for clamping two ends of a hobbing cutterring are arranged on the first sliding rail; a laser measuring instrument is assembled on the electric servo sliding rail in a sliding manner; a storage battery, a memory, a processor and a wirelesscommunication module are also arranged in the casing; the power supply end of the processor is electrically connected with the storage battery; the data end of the processor is electrically connectedwith the memory and the wireless communication module; the communication end of the processor is electrically connected with the communication end of the laser measuring instrument; and the control end of the processor is electrically connected with a driving motor in the electric servo sliding rail. According to the portable intelligent detector and the processing method provided by the invention, the wear quantity of the hobbing cutter ring can be statically detected, and hobbing cutter wear quantity for cutter rings with different blade types and different sizes can be accurately and automatically measured; and in addition, a processing and analyzing method for the hobbing cutter wear data is improved so as to better provide shielding construction service at later stage.

Description

technical field [0001] The invention relates to the measurement technology of hob cutter rings of tunnel boring machines, in particular to a portable hob intelligent detector and a hob wear data processing method. Background technique [0002] The disc hob is the rock-breaking part of the shield machine and is easily worn out. The wear of the cutter directly affects the construction efficiency and construction cost. Therefore, it is necessary to measure the wear amount of the hob cutter ring in time, so as to timely check the relevant faults in the construction and improve the construction efficiency. [0003] At present, calipers are often used to measure the wear of the hob, but one type of caliper can only detect one specification of the hob cutter ring, which has poor versatility; the measurement process relies on manual estimation, and the measurement accuracy is poor; the measurement operation is inconvenient. Data recording is cumbersome; and the clamping plate of th...
