Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a detection device used for tunnel wall detection. Background Art

[0002] During the construction of a tunnel, the tunnel wall is formed by pouring concrete. If voids occur during the pouring process, it will pose a safety hazard. Therefore, it is necessary to detect the tunnel wall to promptly detect the voids in the tunnel wall concrete and take corresponding remedial measures.

[0003] During the detection of the tunnel wall, it is necessary to adjust the detection mechanism to an angle perpendicular to the tunnel wall. The main body of the currently used detection trolley platform is a frame structure with a height of about 3 meters. When detecting different points, due to the arc-shaped structure of the tunnel top wall, manual adjustment of the angle of the detection mechanism is very cumbersome, and it is also very laborious and difficult to carry and move the detection trolley platform. In addition, the mechanism for adjusting the height of the detection mechanism is a lifting mechanism that relies on manpower for pulling and pulling. When facing the tunnel detection height range of 1 to 9 meters, this manual pulling method is laborious and time-consuming, and there are also certain safety hazards.

[0004] Therefore, providing a detection vehicle platform device with a compact structure, easy mobility, and no need for manual adjustment of the height and angle of the detection mechanism has become an urgent problem to be solved in the industry. Utility Model Content

[0046] As another non-limiting embodiment, the crossbeam pressing plate mechanism 10 is further included. The crossbeam pressing plate mechanism 10 is sleeved on the movable crossbeam mechanism 3 and fixed on the bottom frame 1. Specifically, Figure 3 As shown, the crossbeam clamping plate mechanism 10 includes a gate-shaped clamping plate frame 100, a first hand wheel 101 passed through the top of the clamping plate frame 100, a second hand wheel 102 passed through the front end of the clamping plate frame 100, a first pressure plate 103 provided above the inner cavity of the clamping plate frame 100 and connected to the bottom of the first hand wheel 101, and a second pressure plate 104 provided in front of the inner cavity of the clamping plate frame 100 and connected to the bottom of the second hand wheel 102.

[0048] Therefore, if Figure 11 As shown, to ensure detection of seven points E1, E2, E3, E4, E5, E6, and E7 on the tunnel wall, it is necessary to move the pneumatic rod 6 and the ends of the adjustment rod 33 between positions AC, AD, BC, or BD, respectively. Simultaneously, the movable crossbeam 31 moves left and right on the bottom frame 1. These three coordinated actions ensure accurate positioning of the seven points on the tunnel wall. The first positioning axis hole A, the second positioning axis hole B, the third positioning axis hole C, and the fourth positioning axis hole D are all connected to the adjustment rod 33 via quick-release shafts.

[0049] In this embodiment, if Figure 5A 、 Figure 5B as well as Figures 6A to 6C As shown, the upper end adjustment mechanism 7 includes: a horizontal support plate 70, gas springs 71 symmetrically arranged at the front and rear ends of the horizontal support plate 70, a nylon wheel 72 arranged on the top of each gas spring 71, a door-shaped support frame 73 arranged at the center below the horizontal support plate, a U-shaped connecting frame 75 connected to the bottom of the two side frame walls of the support frame 73 through a rotating shaft 74, and an adjusting electric push rod 76, wherein, as shown in FIG. Figure 7 As shown, the bottom end of the central frame of the support frame 73 is provided with a downwardly extending seat 77, and the top of the adjustment electric push rod 76 is movably connected to the seat 77 through a shaft pin 78, as shown in FIG. Figure 8 As shown, the upper portion of the adjustment electric push rod 76 is connected to the front ends of the two side frames of the U-shaped connecting frame 75 through a clamp 79 (blue component).

[0051] In this non-limiting embodiment, to ensure a vertical distance of 10 to 50 mm between the detection frame and the tunnel wall, an adjustment push rod 76 is used to rotate the upper portion about the rotation axis 74, bringing the detection frame into a perpendicular angle with the tunnel wall. A gas spring 71 and nylon wheels 72 are used to maintain a distance of 10 to 50 mm and to maintain friction between the detection trolley platform and the tunnel wall during movement.

The height of the detection mechanism 8 is adjusted by raising and lowering the pneumatic rod 6, and the left and right positioning of the detection mechanism 8 is adjusted by the left and right movement of the adjustment rod 33 and the movable crossbeam 31. That is, through the mutual cooperation of the pneumatic rod 6, the adjustment rod 33 and the movable crossbeam 31, the detection mechanism 8 is accurately positioned at the tunnel point, and then the operation of the electric push rod 76 is adjusted to make the upper end adjustment mechanism 7 move to achieve a vertical distance between the detection mechanism 8 and the tunnel wall between 10-50mm, and then the detection trolley platform device is pushed to move, and the detection mechanism 8 detects the tunnel wall. When an unqualified area is detected, the marking mechanism 9 is started to mark the unqualified area.
