Problems solved by technology

[0003] After the hob wears to a certain extent, it will wear to the mounting seat and even the cutter head. Therefore, once excessive wear occurs, it will cause huge investment in money and time. The current detection method is generally: set Detection column, the detection column is a cavity, the cavity is filled with high-pressure oil, and a pressure sensor is installed on the back side of the detection column to detect the pressure state of the high-pressure oil in the column. When the wear reaches a certain level, the detection column is worn After wear, the high-pressure oil is sprayed out to release the pressure, and the pressure sensor will send an alarm to the host computer after detecting the pressure change
There are the following deficiencies in the above methods: 1. The hydraulic oil has a certain degree of pollution, which affects the construction environment on site. Some of them will fill the detection column with gas with peculiar smell for the convenience of on-site knowledge. The gas will be released after the detection column is worn. The construction personnel are reminded by gas, but it has a great impact on the working environment of the construction personnel; 2. The length of the detection is fixed, and the early warning can only be given after the detection column is worn out after reaching the degree of wear, which cannot provide more Accurately understand the degree of wear

Embodiment 1

[0041] This embodiment provides a shield machine hob wear and positioning detection device, such as figure 1 and Figure 4As shown, it includes at least one base body 1 and a detection assembly, the base body 1 is provided with an installation channel 1-1, and the detection assembly includes an optical transceiver module 4 and a reflector, and the reflector is regularly arranged in the installation channel 1-1 1, the optical transceiver module 4 includes a emitting element 4-1 and a plurality of receiving elements, the reflector is a transparent material, a filling liquid 7 is arranged between adjacent reflectors, and the refractive index of the filling liquid 7 The same as the refractive index of the reflector, when the detection light emitted by the optical transceiver module 4 passes through the reflector and the filling liquid 7, since the refractive index of the reflector and the filling liquid are similar, as long as it is inscribed within the setting error, the detectio...

Embodiment 2

[0048] like Figure 8-9 As shown in the figure, compared with the first embodiment, the main difference of this embodiment is that the form of the reflector used is different, the reflector used in this embodiment is the corner plate 5, and the corner plate 5 is composed of two flat reflectors , there is a certain angle between the two reflective plates. Same as the first embodiment, the corner plate 5 is also made of transparent material, and all the corner plates 5 are also arranged in the installation channel 1-1 according to a certain rule. The vertical angle The plate 5-1 and the horizontal corner plate 5-2 are arranged at intervals, and a filling liquid 7 is arranged between the adjacent corner plates. The positions of the reflected light of the vertical corner plate 5-1 and the horizontal corner plate 5-2 are different, corresponding to There are two receiving elements, the first receiving element 4-2 is used to receive the reflected light of the vertical gusset 5-1, th...

Embodiment 3

[0051] like Figure 11 As shown, compared with the first embodiment, the main difference of this embodiment is that the form of the reflector used is different, the reflector used in this embodiment is the polarizer 6, and the same as the above is that the polarizer The state of 6 is the horizontal polarizer 6-1 and the vertical polarizer 6-2, all polarizers are arranged in parallel, but the deflection angles of the horizontal polarizer 6-1 and the vertical polarizer 6-2 are different, that is, the horizontal polarizer The polarization angles of the plate 6-1 and the vertical polarizer 6-2 are different, the vertical polarizer 6-2 and the vertical polarizer 6-2 are alternated, and a filling liquid 7 is arranged between the adjacent polarizers, and the The detection light is point-shaped, and after being reflected by the polarized light at the end, the reflected light is called an ellipse, such as Figure 12 Shown is the reflected light spot of vertical polarizer 6-2, as ima...

Abstract

The invention discloses a shield tunneling machine hob abrasion positioning detection device which comprises at least one base body and a detection assembly, an installation channel is formed in the base body, the interior of the installation channel is divided into a plurality of separation cavities in the length direction of the installation channel, and the detection assembly is provided with active detection elements and passive detection elements. The passive detection elements are arranged in the separation cavities, and when the base body is abraded to the corresponding separation cavities, the passive detection elements excite the active detection elements to conduct detection and recognition. The interior of the detection base body is divided into multiple sections of separation cavities, when the corresponding separation cavities are abraded, detection is carried out through the detection assembly, and the abrasion degree of the hob can be accurately known through the abrasion degree of the base body.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a device for detecting the wear and positioning of hob cutters of shield machines. Background technique [0002] The front part of the shield machine is the shield head. The excavation of the shield machine is mainly realized by the shield head. The end of the shield head is the cutter head. There are several cutters on the cutter head. The cutter is also different, and the hob cutter is used for the rock formation. The hob cutter is set on the cutter head through the rotation of the cutter seat. During the excavation process, the hydraulic system inside the shield acts on the cutter head, so that the cutter head will roll over the cutter head. The cutter is pressed on the rock formation, and the cutter head is driven to rotate by its own driving device, and the hob cutter also rotates passively while revolving to grind the rock formation. [0003] After the hob is worn ...
