Problems solved by technology

When the tool is excavated under the working condition exceeding its rated pressure, the tool wear speed is greatly accelerated. At this time, if the tool wear degree is not detected in time, a TBM cutter head wear accident will occur, resulting in damage to the cutter head and TBM shutdown.

Embodiment 1

[0051] Such as Figure 1-6 As shown, Embodiment 1 of the present disclosure provides a TBM cutter head tool pressure equalization and wear detection system, including a single hob 9 or double hob 10 , a cutter head 11 , a cutter head mounting seat 12 and a hydraulic base 17 .

[0052] The schematic diagram of a single hob is shown in figure 1 As shown, the schematic diagram of the double hob is shown in figure 2 As shown, the single hob 9 or the double hob 10 all include a magnetic latch 1, a buffer pad 2, a hob seat 3, a hob shaft support 4, a hob shaft 5, a hob 6, a laser emitter 7 and Laser receiver 8.

[0053] In this embodiment, the magnetic plug 1 is a square structure matching the magnetic square hole 14 .

[0054] Such as image 3 As shown, the cutter head mounting base 12 is integrally cast with the cutter head 11 , the hydraulic base 17 includes a hydraulic rod 13 and a magnetic socket 16 , and the magnetic socket 16 includes a magnetic square hole 14 and an ele...

Embodiment 2

[0073] Embodiment 2 of the present disclosure provides a TBM tool pressure balanced wear detection method, using the TBM tool pressure balanced wear detection system described in Embodiment 1, including the following steps:

[0074] A. Weld and fix the hydraulic rod to the bottom of the cutterhead mount, and weld and fix the magnetic socket to the top of the hydraulic rod;

[0075] B. Turn off the electromagnet, insert the single hob (double hob) into the magnetic square hole through the magnetic latch to ensure that the direction of the blade is circular. At this time, start the electromagnet to complete the magnetic fixation;

[0076] C. Start the cutter head for excavation. When the TBM encounters soft and hard uneven ground, the pressure on individual cutters exceeds its rated pressure. At this time, the pressure-sensitive sensor in the hydraulic rod sends an overload signal and the hydraulic rod shrinks to reduce the pressure on the cutter. up to less than its rated value...

Embodiment 3

[0080] Embodiment 3 of the present disclosure provides a tunnel boring machine, including the TBM tool pressure equalization wear detection system described in Embodiment 1 of the present disclosure.

Abstract

The disclosure provides a TBM tool pressure equalization wear detection system, including a hob, a cutter head, a cutter head mounting seat and a hydraulic base, the cutter head is fixedly connected to the cutter head mounting seat, and the hydraulic base is connected to the cutter head mounting seat Fixed connection; the hydraulic base includes a hydraulic rod and a magnetic socket fixed to the end of the hydraulic rod, the magnetic socket includes a magnetic hole and a magnetic element, and the hob is fixed in the magnetic hole through the magnetic element ;When the pressure on the tool is greater than the preset pressure, the hydraulic rod shrinks, reducing the pressure on the tool until it is less than the preset pressure value; The wear of the tool is reduced, the consumption of the TBM tool is reduced, and the cost is saved.

Description

technical field [0001] The present disclosure relates to the technical field of TBM, in particular to a TBM tool pressure equalization wear detection system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] A large number of cross-basin water diversion projects will be built in the western region of my country, and a large number of international cooperation water conservancy, transportation, and energy projects are also under construction. The construction of deep-buried long tunnels has become the key link of the above-mentioned projects. Full-face rock tunnel boring TBM (Tunnel boring machine) will be widely used in tunnel construction due to its fast, high-quality, safety, environmental protection, economical and many other advantages, and has an irreplaceable position in deep buried long tunnels. [0004] The inventors of...
