Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation to the present invention.

[0025] A tunnel surface image acquisition device and a tunnel surface quality detection system, such as figure 1 As shown, the trolley base 1 is included, and the trolley base 1 is connected with a column 2. The column 2 includes a turning edge 3, and the turning edge 3 is connected to the side of the top of the column 2 by rotating around a horizontal axis. The side of the turning edge 3 A connecting rod 31 is connected, and the connecting rod 31 includes a vertically upward working state and a downward storage state as the folded edge 3 rotates.

[0026] Such as figure 1 As shown, the column 2 is connected with a battery, a display, a display host, and a control switch; by detecting the speed sensor and the odometer installed inside the car, the walk...

Abstract

The invention discloses a tunnel surface image collection device and a tunnel surface quality detection system, relates to the technical field of tunnel detection devices, and solves the problems thatthe manual detection speed is low, the efficiency is low, and the time for adapting to modern subway tunnel detection windows becomes shorter and shorter. The device comprises a trolley base, a standcolumn is connected to the trolley base, a center shaft is arranged at the top end of the stand column, the center shaft and the circle center of a tunnel are concentrically arranged, and a pluralityof photographing units are arranged on the center shaft in a surrounding mode; the photographing unit comprises a camera for photographing a detection area on the surface of the tunnel and an auxiliary light source for irradiating the detection area on the surface of the tunnel and providing illumination for photographing of the camera; and the detection areas shot by the adjacent cameras are partially overlapped. Therefore, the defects of leakage, cracking and the like of the tunnel can be accurately positioned, tunnel image information can be fully collected, and meanwhile portability is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel detection devices, in particular to a tunnel surface image acquisition device and a tunnel surface quality detection system. Background technique [0002] In recent years, with the rapid development of urban construction and the continuous expansion of urban scale, urban subway transportation has developed rapidly with its unique advantages. Subway tunnels have extremely high requirements for operational safety. In the process of operation, management and maintenance of subway tunnels, it is necessary to detect and deal with structural defects such as cracks and water leakage in a timely manner. At present, the structural detection of subway tunnels mainly relies on manual detection methods. Manual detection is slow and inefficient, and it is increasingly unsuitable for the short detection window of modern subway tunnels. Contents of the invention [0003] The purpose of the present invention i...
