Embodiment 1

[0037] Such as figure 1 shown and figure 2 As shown, the present invention provides a kind of inspection system of traffic tunnel shaft, including guide rope 8, inspection platform, lifting power device, detection instrument and control processing equipment;

[0038] The guide rope 8 is a metal rope with a rough surface, which is used for guiding and pulling the lifting and lowering of the inspection platform;

[0039] There is a circular hole 6 on the top and bottom of the inspection platform, and the guide rope 8 passes through the two circular holes 6;

[0040] The lifting power device is connected with the inspection platform and installed on the guide rope 8, which is used to fix the inspection platform on the guide rope 8, and is also used to provide lifting and lowering power for the inspection platform;

[0041] The detection instrument is installed on the inspection platform to detect the structural condition of the shaft;

[0042] The control processing equipment...

Embodiment 2

[0056] The inspection platform in Example 1 is equipped with 4 cameras, which correspond to the detection of a certain direction within a range of 90 degrees. Since the well wall is a curved surface, after the image taken by it is transmitted to the industrial computer, the on-site operators can see It is also an image of the shaft wall with a certain radian, and the position of the camera is fixed, so the operator cannot use the image to accurately locate the position of the shaft wall where surface water leakage and block drop occur.

[0057] In order to solve the above-mentioned technical problems, further optimization on the basis of Embodiment 1, the following technical solutions are adopted: the wellhead of the shaft is equipped with a cross-shaped marker, and the image collector 9 is calibrated with the cross-shaped marker through monocular visual recognition. Specifically, in this embodiment, the cross-shaped metal strip installed at the wellhead is used as a marker, an...

Embodiment 3

[0059] Because of the depth of the shaft, the shallow ones are two to three hundred meters, and the deep ones can reach five or six hundred meters. During the actual inspection process, the bottom of the shaft will have wind blowing from the bottom of the shaft to the wellhead. In the case of high wind speed, it will blow the inspection platform hanging on the flat strand steel wire rope, causing the inspection platform to shake from side to side. Affect the detection effect of detection equipment. In order to solve the above-mentioned technical problems, further optimization is carried out on the basis of Embodiment 1, and a windshield 7 is installed under the lower circular plate 2 . The windshield 7 adopts a 1mm thick steel plate to form a conical shape, and is fixedly connected with the lower circular plate 2, such as by welding. The top of the cone of the windshield 7 has a circular hole 6 of 4cm, which is used for the plane strand steel wire rope to penetrate. By using...

Abstract

The invention provides a traffic tunnel vertical shaft inspection system, which comprises a guide rope, an inspection platform, a lifting power device, a detection instrument and a control processingdevice, wherein the guide rope is a metal rope with a rough surface and is used for guiding and dragging the ascending and descending of the inspection platform; the lifting power device is connectedwith the inspection platform, is mounted on the guide rope, is used for fixing the inspection platform on the guide rope, and is also used for providing ascending and descending power for the inspection platform; the detection instrument is arranged on the inspection platform and is used for detecting the structural condition of the vertical shaft; the control processing device is electrically connected with the lifting power device and the detection instrument and used for controlling the lifting power device to drive the inspection platform to ascend and descend, and is also used for controlling the detection instrument to detect, receive and store detection data. The technical problems that a vertical shaft inspection system is complex in structure, high in system manufacturing cost andcomplex in system processing image recognition operation during inspection can be solved.

Description

technical field [0001] The invention relates to the technical field of detecting buildings, in particular to an inspection system for traffic tunnel shafts. Background technique [0002] At present, in traffic tunnel projects such as extra-long highways or railway tunnels, shafts or inclined shafts are usually set up for tunnel operation ventilation and disaster prevention and rescue. For these shafts and inclined shafts, after they are completed and put into operation, they need to be inspected or tested regularly to determine the structural conditions of the shafts and inclined shafts, such as whether there are cracks on the shaft wall and whether there is water leakage in the shaft. For the inspection of the structural conditions of such wells, the traditional method is mainly to go to the specific location for visual inspection by technicians. Since the shaft is vertically downward, the depth is as short as one or two hundred meters and as deep as one or two kilometers,...
