Abstract

The embodiment of the invention provides a channel surface image acquisition device and a tunnel boring machine. The channel surface image acquisition device comprises: a shell provided with an opening; a photographing unit which comprises a plurality of cameras, wherein the cameras shoot the detection area on the surface of the channel through the opening, and the photographing unit is configured in a manner that the photographing areas of the cameras are mutually spliced to form a continuous photographing area; a lighting unit which is used for irradiating the detection area to provide a lighting light source for the camera, wherein the lighting area, on the detection area, of the light source of the lighting unit can cover the continuous shooting area; a bearing bracket which is connected to the shell and is used for mounting the cameras and the lighting unit; and an information collector which is arranged on the shell and is used for collecting position information of the cameras relative to the detection area. According to the channel surface image acquisition device provided by the embodiment of the invention, at least part of the sub-images are spliced to obtain a complete working face image, the life safety of construction workers is guaranteed, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a channel surface image acquisition device and a tunnel boring machine. Background technique [0002] Tunnel boring machines are widely used in tunnel construction because of their fast construction speed, small construction-affected area, and relatively safe construction environment. During the construction process, timely, effective and accurate knowledge of the rock mass information on the surface of the channel is very important for the safety of construction personnel and construction efficiency. [0003] The inventors found that in the prior art, images of the tunnel surface were collected manually after the roadheader had completely stopped running. This method had a harsh working environment and low efficiency, and it was also difficult to obtain accurate image information of the tunnel surface. Contents of the invention [0004] In view of this, the presen...
