Embodiment Construction

[0026] The core of the present invention is to provide a hob test bench for shield tunneling and TBM, which can simulate the rock and soil cutting conditions of the hob under different working conditions, so as to study the rock breaking efficiency and wear mechanism of the hob, and then extend the Hob life.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Please refer to Figure 1 to Figure 6 , figure 1 Structural schematic diagram when the shield tunneling machine and TBM hob test bench provided by the present invention are in a vertical state; figure 2 for figure 1 Partial enlarged view of the middle H part; image 3 Schematic diagram of the structure when the shield tunneling machine and the TBM hob test bench are in a horizontal state provided by the present inv...

Abstract

The invention discloses a shield and TBM (tunnel boring machine) hob test bed which comprises a test bed main unit and supports distributed symmetrically. The test bed main unit is rotatably connected with the supports, the rotation angle is at least 90 degrees, and accordingly the test bed main unit can be switched between a perpendicular state and a horizontal state. The test bed main unit is rotatably connected with the supports and can rotate at least 90 degrees, so that the test bed main unit can simulate actual moving conditions of a hob in the perpendicular state or horizontal state, cutting characteristics of the hob in different operation states can be researched, the hob is modified on the basis, and the service life of the hob is prolonged.

Description

technical field [0001] The invention relates to a hob test stand, in particular to a shield and TBM hob test stand. Background technique [0002] The hob is the main tool for cutting and breaking rock on the shield (shield tunnel boring machine) or TBM (Tunnel Boring Machine, tunnel boring machine). broken rock. When tunneling under different geological conditions and different working parameters, the wear and failure of hobs are different. Due to the failure of the cutter, the cutter needs to be replaced during the excavation process, but the replacement of the cutter is not only a lot of work but also dangerous, so it is necessary to check the hob, especially the load characteristics of the cutter and the rock and soil when multiple hobs are combined to cut the broken rock and soil. Analyze the crushing effect of the hob in order to improve the structure and working parameters of the hob accordingly and prolong the service life of the hob. [0003] It should be pointed ...
