Shield tunneling machine and method capable of achieving cutter abrasion image detection

Abstract

The invention relates to a shield tunneling machine and method capable of achieving cutter abrasion image detection. The shield tunneling machine comprises a soil bin, a front shield, a middle shield and a tail shield which are sequentially arranged from front to back, wherein a bin partition plate is arranged between the soil bin and the front shield, an opening is formed in the bin partition plate, a sealing plate capable of being automatically opened and closed is arranged at the opening, a storage barrel is fixed to the side, away from the soil bin, of the bin partition plate, one end of the storage barrel is open and inserted into the opening, an end plate is detachably mounted at the other end of the storage barrel, a binocular camera and a driving assembly are arranged in the storage barrel, the driving assembly can drive the binocular camera to extend into or retract into the soil bin from the storage barrel, the binocular camera can complete camera shooting of a cutter in the soil bin and transmit the image to an upper computer, and the upper computer can complete three-dimensional modeling of the cutter according to image information of the binocular camera and judge the abrasion degree of the cutter. According to the invention, imaging detection of the cutter in the soil bin of the shield tunneling machine can be completed, and the efficiency and accuracy of cutter wear detection are improved.

Description

technical field [0001] The disclosure belongs to the technical field of geotechnical engineering, and in particular relates to a shield machine and a method capable of realizing tool wear image detection. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Shield machine knives need to be replaced in time after wear or failure, otherwise it will lead to excessive wear, breakage, displacement of the knives, abnormal damage to the bearings and even severe wear of the cutter head, which will greatly reduce the tunneling efficiency. Among the existing tool wear detection methods, the method of opening the cabin and directly inspecting it by divers is the most effective, but under the action of earth pressure and water pressure in the formation, there is a great safety risk in opening the cabin of the shield machine.

Problems solved by technology

[0004] In a technical solution for shield machine tool detection through 3D image modeling and comparison that the inventor has learned, in order to meet the sealing requirements of the soil tank and not affect the normal operation of the shield soil tank, each inspection requires Installing the detection device on site will waste a lot of time and the airtightness of the installation is limited by the proficiency of the current operator. After the detection is completed, the detection device must be removed manually

[0005] At the same time, the tool shooting process requires the cooperation of the rotation of the cutter head to shoot different tools, and it is impossible to completely stop the machine. The rotation of the cutter head will easily cause changes in water pressure and earth pressure, and the detection process will increase instability.
