DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 In this embodiment, a tunnel level monitoring device based on laser ranging includes a laser emitting and receiving device 1. An electric telescopic rod 2 is arranged at the bottom of the laser emitting and receiving device 1. The bottom of the electric telescopic rod 2 is rotatably connected to a base 3. A mounting plate 4 is fixedly installed at the bottom of the laser emitting and receiving device 1. An adjusting mechanism 5 is arranged at the bottom of the mounting plate 4. The laser emitting and receiving device 1 aims at the cross center of the reflecting medium to emit laser. After the laser is reflected back, the elevation of the monitoring point is calculated, thereby obtaining the change of the vertical displacement of the point to be measured. The measured data is then processed and uploaded through a wireless transmission module. The 4G network is used for transmission. Finally, the monitoring data is sent to a cloud platform, and the cloud platform automatically calculates and processes the monitoring data.

[0023] Specifically, a moving platform 501 is fixedly installed on the top of the electric telescopic rod 2, a moving groove 502 is provided on the top wall of the moving platform 501, a moving block 503 is slidably connected inside the moving groove 502, a limiting hole 504 is provided on the front side wall of the moving platform 501, a limiting groove 505 is provided on the front side wall of the moving block 503, an adjusting shell 506 is fixedly installed on the top of the moving block 503, a first rotating rod 507 is rotatably connected inside the adjusting shell 506, an external fixed sleeve of the first rotating rod 507 is provided with a driving gear 508, a second rotating rod 509 is rotatably connected inside the adjusting shell 506, an external fixed sleeve of the second rotating rod 509 is provided with a passive gear 510, and the second rotating rod 5 A connecting rod 511 is fixedly installed on the top of 09. During the monitoring work, the laser emitting and receiving device 1 can be moved and adjusted in multiple directions. When translation adjustment is required, the limit rod 6 between the limit hole 504 and the limit groove 505 can be removed, and the moving block 503 can be pushed to move in the moving groove 502. After moving to the appropriate position, the limit rod 6 can be inserted into the limit hole 504 at the corresponding position for limiting. By turning the handle, the first rotating rod 507 and the active gear 508 are driven to rotate, and the passive gear 510 and the second rotating rod 509 are driven to rotate. Finally, the laser emitting and receiving device 1 can be driven to swing up and down and emit inclined lasers for tilt detection.

[0024] Specifically, a limiting rod 6 is arranged between the limiting hole 504 and the limiting groove 505. The number of the limiting holes 504 is more than five. By inserting the limiting rod 6 into the limiting holes 504 and the limiting groove 505 at different positions, the laser emitting and receiving device 1 at the corresponding position can be limited.

[0025] Specifically, a concave sliding hole is opened on the outer wall of the adjustment shell 506, and the top wall of the connecting rod 511 extends to the outside of the adjustment shell 506 through the concave sliding hole. The connecting rod 511 slides in the concave sliding hole. The opening range of the concave sliding hole is the swingable range of the laser transmitting and receiving device 1.

[0026] Specifically, the handle is rotatably connected to the adjustment housing 506, and four expansion screws are provided on the base 3, and the base 3 is fixed to the ground using the 8mm expansion screws.

[0027] When implementing, follow these steps:

[0028] 1. First, fix the device at the monitoring location with expansion screws, and adjust the position of the laser transmitting and receiving device 1 according to the position of the monitoring target. If height adjustment is required, the height of the laser transmitting and receiving device 1 can be adjusted by controlling the electric telescopic rod 2;

[0029] Then, when translation adjustment is required, the limiting rod 6 between the limiting hole 504 and the limiting groove 505 can be removed, and the moving block 503 can be pushed to move in the moving groove 502, and then the limiting rod 6 can be inserted into the limiting hole 504 at the corresponding position to limit the position when it moves to the appropriate position;

[0030] Finally, when tilt detection is required, turning the handle can drive the laser emitting and receiving device 1 to swing up and down and emit tilted lasers. At the same time, by rotating the mounting plate 4, the electric telescopic rod 2 can be driven to rotate on the base 3 to adjust the direction of movement. There is no need to move the device as a whole, and then monitoring is performed by turning on the laser emitting and receiving device 1.

[0031] In summary, the laser ranging tunnel level monitoring device can perform multi-directional movement and adjustment of the laser emitting and receiving device 1 during monitoring by setting an adjustment mechanism. For example, when height adjustment is required, the height of the laser emitting and receiving device 1 can be adjusted by controlling the electric telescopic rod 2; the limit rod 6 between the limit hole 504 and the limit groove 505 can be removed, and the moving block 503 can be pushed to move in the moving groove 502, and then the limit rod 6 can be inserted into the limit hole 504 at the corresponding position for limiting when it moves to a suitable position; at the same time, by rotating the mounting plate 4, the electric telescopic rod 2 can be driven to rotate on the base 3 to adjust the direction of movement, without the need to move the device as a whole, and without the need for the staff to hold it for measurement. By rotating the handle, the laser emitting and receiving device 1 can be driven to swing up and down and emit an inclined laser to perform tilt detection, and by setting the laser emitting and receiving device 1, the monitoring efficiency can be improved, the original process automatic real-time monitoring can be realized, the monitoring accuracy is high, the installation is convenient, and secondary recycling can be realized.
