Detection device of roadheader and roadheader

Abstract

The invention discloses a detection device of a roadheader and the roadheader. The detection device includes: a rotating plate, which is rotatably arranged on the partition plate, and a through hole is arranged on the rotating plate; a fender, a connecting rod is arranged on the fender, and the connecting rod is arranged on the rotating plate and is opposite to the rotating plate. It can move axially; the pipeline camera component and the fixed component, the fixed component is arranged on the rotating plate and communicates with the through hole correspondingly, the fixed component is used to fix the pipeline camera component, when the detection device is not working, the rotating plate rotates to the non-working position so that The connecting rod extends into the observation hole to seal the observation hole; when the detection device is working, the connecting rod extends out of the corresponding observation hole and the rotating plate rotates to the working position so that the through hole and the observation hole are connected correspondingly so that the pipeline camera components pass through the through hole in turn And observation hole to extend into the high pressure environment. The detection device of the invention has a simple and compact structure, and is especially suitable for roadheaders with narrow installation and observation spaces.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a detection device for a roadheader and a roadheader. Background technique [0002] During the tunnel excavation process of the roadheader, the mud or muck filled with a certain pressure in the soil bin is used to balance the rock and soil pressure on the tunnel face, and the cutter head of the roadheader is also completely immersed in the mud or muck in the soil bin. During the shield construction process, it is necessary to regularly check the cutter head, the wear of the cutter, the actual condition of the muck in the soil bin, or the accumulation of muck and equipment wear in the air cushion cabin of the slurry roadheader. However, since the inside of the soil bin and the air cushion cabin is a closed, dark space full of mud or muck, personnel cannot directly enter. The traditional inspection method is to lower the mud or muck liquid level in the soil bin to below the ce...

Problems solved by technology

However, the video window of the video monitoring device is easily covered and blocked by viscous muck, especially for the earth pressure balance shield, the viscous mud will inevitably completely block the video observation port and the video device, which leads to the device not working

[0004] Although a related technology has proposed a device that enables operators to conduct video observation of the situation in the soil bin or air cushion cabin outside the soil bin or air cushion cabin, but this device has a complex structure, a large installation size, and lack of protection against observation. It is not suitable for use in small-diameter roadheaders with narrow spaces and densely packed pipelines.
