Embodiment 1

[0034] Example 1, such as figure 1 , image 3 , Figure 4 As shown, an online real-time detection system for TBM hob wear includes an industrial computer 7, which is set on the host platform 4, which is the TBM, and the industrial computer 7 realizes data collection and control command sending and transmission. The industrial computer 7 is respectively connected with the laser telescopic device in front of the TBM and the hob wear laser detector through the data cable 8. The industrial computer 7 controls the free hierarchical expansion and contraction of the laser telescopic device. The wear state of the laser is sent to the industrial computer 7, and the number of the laser telescopic device and the hob wear laser detector is set to several. The laser telescopic device is distributed and installed on the TBM cutter head 3, and multiple lasers can be set according to the setting of the detection point. retractable device. Mounting holes are arranged on the TBM cutter head ...

Embodiment 2

[0042] Embodiment 2, an online real-time detection method for TBM hob wear, the steps are as follows:

[0043] Step 1: Arrange detection points on the TBM cutter head 13 according to the layout of the TBM cutter head 13, install a laser telescopic device at each detection point, and install the hob wear laser detector on the top of the laser telescopic device; the layout of the detection points They are evenly distributed on the cutter head and arranged reasonably according to the type of cutter head to ensure that the arrangement of these detection points can cover all hob cutter positions.

[0044] Step 2: When it is necessary to change steps in the first ring of TBM excavation, the hob wear detection can be carried out at this time, and the switch of the hob measuring device in the TBM main control room 9 is turned on, and the industrial computer 7 controls the extension of the laser telescopic device to extend rapidly To the limit wear standard of the 13-side cutter of the...

Abstract

The invention provides an online TBM hob abrasion real-time detection system and method, thereby solving problems that an existing hob abrasion detection system is complex, is greatly influenced by the environment and is inaccurate in measurement precision. The detection system comprises an industrial personal computer connected with laser telescopic devices and hob abrasion laser detectors, wherein multiple the laser telescopic devices and hob abrasion laser detectors are arranged; and the laser telescopic devices are distributed and installed on a TBM cutterhead, and the hob abrasion laser detectors are installed at the tops of the laser telescopic devices. The industrial personal computer is connected with a TBM main control room. Meanwhile, the invention discloses an online real-time detection method. Real-time monitoring of hob abrasion can be achieved in different tunneling environments, the automation degree is high, and the maintenance risk of maintenance personnel is greatly reduced; the method is easy to operate, the protection device is reasonable, hob abrasion information collection can be completed within the step changing time of the TBM, and the real-time performanceand accuracy of hob detection are guaranteed.

Description

technical field [0001] The invention relates to the technical field of wear monitoring of hob cutters of full-face boring machines, in particular to an online real-time detection system and method for wear of TBM hobs. Background technique [0002] With the country's large-scale construction investment in the field of infrastructure, TBM and shield machines have been widely used in various tunnels due to their advantages such as safety and speed. The cutting tool is a key part and a vulnerable part on the TBM. The wear mode of the hob includes normal wear and abnormal wear. The normal wear is caused by the abrasive effect of the rock on the cutting tool, which basically accounts for more than 80-90% of the cutting tool wear. The detection of hob wear is directly related to the improvement of engineering construction excavation efficiency and economic benefits, so the research on real-time detection of hob wear is very important for TBM construction. [0003] At present, the...
