Device and method for visually detecting front part of cutter head of cutter of shield tunneling machine

Abstract

The invention discloses a device and a method for visually detecting the front part of a cutter head of a cutter of a shield tunneling machine, and the device and the method are safe, convenient, fast, economical and reliable. The device comprises a camera device, a lighting device, a washing device, a first propulsion device, a second propulsion device, a third propulsion device, a data acquisition device and a bubble cabin of the shield tunneling machine, wherein the camera device comprises a front end camera and a lateral camera; the front wall of the bubble cabin of the shield tunneling machine is provided with three circular holes; spherical hinges are welded in the circular holes, respectively, and ball valves for connecting the camera device, the lighting device and the washing device are arranged in the circular holes, respectively; the first propulsion device, the second propulsion device and the third propulsion device are connected with the camera device, the lighting device and the washing device by screw threads and are respectively connected with the front wall of the bubble cabin of the shield tunneling machine by the corresponding ball valve. The device and the method have the beneficial effects that large-area damage or unnecessary cabin opening inspection and cutter replacement, which are caused by the fact that the cutter is not replaced in time after being damaged, can be avoided, and the service life of the cutter is prolonged.

Description

technical field [0001] The invention relates to the related technical field of shield machine tool wear detection, in particular to a front-side visual detection device and method for shield machine tool cutter heads in tunnel shield construction. Background technique [0002] During shield tunneling, tool wear is unavoidable. After a small number of tools are worn out, if they are not detected and replaced in time, the wear rate of other tools on the cutter head will be greatly accelerated. However, tool replacement must be carried out under pressure, which is characterized by high safety risks, high costs, and long work periods. Therefore, man-made arbitrary and blind replacement of tools results in extended construction period, increased engineering costs and safety risks. The application of the traditional shield cutterhead wear monitoring system to this project will encounter shortcomings such as high safety risks, high economic costs, and long construction periods, a...

Problems solved by technology

Among the above methods, the method of opening the cabin for inspection is the most direct and effective, but it has a high risk, which may cause the collapse of the excavation surface, thereby affecting the safety of the surrounding buildings of the tunnel, and is expensive

The tool wear sensing device can only be installed on a small number of tools, and cannot sense the wear of other tools, and cannot detect partial wear and abnormal wear

Odor Additives Not Effective in EPB Shields and Slurry Shields

The tunneling parameter analysis method is to establish the total thrust, Empirical relationship between total torque and advance speed, which does not accurately predict tool wear
