Description

Technical Field

[0001] The utility model belongs to the field of collapse monitoring devices, and particularly refers to a ground collapse monitoring device. Background Art

[0002] Geological monitoring technology has been widely applied to various engineering projects to prevent geological disasters. With the acceleration of the urbanization process, there are more and more underground projects such as subways and tunnels, and the risk of ground collapse also increases accordingly.

[0003] The existing ground collapse monitoring methods mainly include manual inspection and video monitoring. The measurement data of manual inspection is prone to large data fluctuations due to improper adjustment of the measurement position and height, which affects the measurement results. Most of the existing collapse monitoring devices are equipped with laser rangefinders at fixed intervals for measuring fixed intervals. For the existing underground pipelines with some sections being long-distance pipelines of dozens of kilometers, a large number of laser rangefinders are required, resulting in a high monitoring cost. Summary of the Utility Model

[0004] The technical problems to be solved by the utility model are that the measurement results of manual inspection are prone to large deviations due to improper adjustment, and the use cost of laser rangefinders set at fixed intervals is relatively high.

[0005] To solve the above problems, the following technical solutions are adopted in the utility model: The ground collapse monitoring device proposed by the utility model includes a laser rangefinder. A display screen and a transmitting hole are arranged on the front side of the laser rangefinder. The device also includes a mounting rack, a control mechanism and a connecting mechanism. An installation groove is formed in the middle of the mounting rack. The control mechanism is arranged on the lower side of the laser rangefinder. The control mechanism includes a rotating shaft. The rotating shaft is slidably connected to the installation groove and penetrates through the installation groove. A limiting block is fixedly arranged at the upper end of the rotating shaft. The limiting block is slidably and fittingly connected to the installation groove. The connecting mechanism is arranged above the mounting rack. The connecting mechanism includes a turntable. A clamping groove is formed in the lower part of the turntable. The clamping groove is slidably and fittingly connected to the limiting block. A connecting groove is fixedly arranged on the turntable. The laser rangefinder is connected to the connecting groove in a pluggable manner.

[0006] Further, the mounting rack further includes mounting bolts. The mounting bolts are threadedly connected to the mounting rack and penetrate through the mounting bolts.

[0007] Further, the control mechanism further includes a bottom plate and fixing bolts. The bottom plate is movably connected to the lower part of the mounting rack. The fixing bolts sequentially penetrate through the mounting rack and the bottom plate. A fixing nut is threadedly connected to the lower part of the fixing bolts.

[0008] Further, the rotating shaft is rotatably connected to the bottom plate and penetrates through the bottom plate. A motor is fixedly arranged at the lower part of the bottom plate. The rotating shaft is shaft-connected to the motor shaft.

[0009] Further, the motor adopts a slow-speed motor.

[0010] Furthermore, springs are provided at both the front and rear parts inside the connecting groove. One end of each spring is fixedly connected to the turntable, and a clamping plate is fixedly provided at the other end of the spring. The clamping plate is slidably connected to the inside of the connecting groove, and the clamping plate is in contact with and connected to the lower part of the laser rangefinder.

[0011] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0012] The ground collapse monitoring device proposed in this solution facilitates the quick disassembly and assembly of the device by fixedly setting the mounting frame, movably connecting the control mechanism and the connecting mechanism to the mounting frame, and setting the laser rangefinder and the connecting mechanism as pluggable connections. The mounting frame is left at the pre-measurement position without changing its position, ensuring accurate measurement data. Moreover, during subsequent measurements, the control mechanism, the connecting mechanism, and the laser rangefinder can be quickly installed on the mounting frame without the need to use a large number of laser rangefinders for fixed-point installation, thus saving the monitoring cost.

The control mechanism 3 is arranged below the laser rangefinder 1. The control mechanism 3 includes a rotating shaft 303. The rotating shaft 303 is slidably connected to the installation groove 202 and penetrates through the installation groove 202. A limiting block 304 is fixedly provided at the upper end of the rotating shaft 303. The limiting block 304 is slidably and fittingly connected to the installation groove 202. The connecting mechanism 4 is arranged above the mounting bracket 2. The connecting mechanism 4 includes a turntable 401. A clamping groove 402 is formed in the lower part of the turntable 401. The clamping groove 402 is slidably and fittingly connected to the limiting block 304. A connecting groove 403 is fixedly provided on the turntable 401. The laser rangefinder 1 is connected to the connecting groove 403 in a pluggable manner.

[0021] As Figure 1 shown, the mounting bracket 2 further includes a mounting bolt 201. The mounting bolt 201 is threadedly connected to the mounting bracket 2 and penetrates through the mounting bolt 201 for pre-installing and fixing the mounting bolt 201.

[0022] As Figures 1-3 shown, the control mechanism 3 further includes a bottom plate 302 and a fixing bolt 305. The bottom plate 302 is movably connected to the lower part of the mounting bracket 2. The fixing bolt 305 sequentially penetrates through the mounting bracket 2 and the bottom plate 302. A fixing nut 306 is threadedly connected to the lower part of the fixing bolt 305 for connecting and fixing the bottom plate 302 and the mounting bracket 2. The rotating shaft 303 is rotatably connected to the bottom plate 302 and penetrates through the bottom plate 302. A motor 301 is fixedly provided at the lower part of the bottom plate 302. The rotating shaft 303 is axially connected to the motor 301 for controlling the rotation of the rotating shaft 303 and the turntable 401. The motor 301 uses a slow-speed motor 301.

[0023] As Figure 1 shown, springs 405 are provided on both the front and rear parts inside the connecting groove 403. One end of the spring 405 is fixedly connected to the turntable 401. The other end of the spring 405 is fixedly provided with a clamping plate 404. The clamping plate 404 is slidably connected to the inside of the connecting groove 403. The clamping plate 404 abuts against the lower part of the laser rangefinder 1 for installing and fixing the laser rangefinder 1.

[0024] During specific use, the mounting bracket 2 is fixed to the inner wall of the pipeline using the mounting bolts 201. The rotating shaft 303 and the quasi-positioning block 304 are aligned and inserted into the mounting groove 202.
