Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, the present invention provides a foundation pit displacement monitoring point layout device, including a layout device body 1, a mounting column 2 and a detection rod 3.

[0026] As a technical optimization of this utility model, by setting up a detection buffer component 4, the elastic ring 41 can buffer and reduce the vibration force, thereby reducing the impact of the vibration force on the main body 1 of the installation device. The vibration sensor 42 can detect the vibration force, and when the vibration force reaches the threshold, it can send a signal to the controller 10. The universal shaft 44 can facilitate the position movement and adjustment of the connecting rod 45. When subjected to vibration, the inertia and gravity of the sand box 46 are used to offset part of the vibration energy.

[0027] refer to Figure 3 The adjustable shock absorption assembly 5 includes an electric push rod 51, a connecting groove 52 is provided on the top of the elastic ring 41, a movable column 53 is movably connected inside the connecting groove 52, the output end of the electric push rod 51 is installed inside the movable column 53, a pressure plate 54 is installed on the top of the movable column 53, and the bottom of the pressure plate 54 is installed with the top of the elastic ring 41.

[0028] As a technical optimization of this utility model, by setting up the shock absorption adjustment component 5, when the vibration sensor 42 sends a signal to the controller 10 during use, the controller 10 can receive and process the signal and start the electric push rod 51, so that the output end of the electric push rod 51 pushes the moving column 53 to move. The movement of the moving column 53 can drive the pressure plate 54 to move. The movement of the pressure plate 54 can press and push the top of the elastic ring 41, thereby adjusting the pressure of the pressure plate 54 on the elastic ring 41 to adapt to different degrees of vibration and ensure that the device can maintain good stability in various complex vibration environments.

[0029] refer to Figure 3 A movable plate 6 is installed on the top of the electric push rod 51, and a rubber plate 7 is installed on the top of the movable plate 6. The top of the rubber plate 7 is installed with the bottom of the connecting plate 43.

[0030] As a technical optimization of this utility model, by setting up a movable plate 6 and a rubber plate 7, the movable plate 6 provides support for the use of the electric push rod 51, and the rubber plate 7 can dampen and buffer the vibration between the movable plate 6 and the connecting plate 43, reducing the vibration force on the detection rod 3 during use, so that the detection rod 3 can be used stably.

[0031] refer to Figure 3 The top of the elastic ring 41 is provided with a mounting groove 8, and the bottom of the clamping plate 54 is provided with a hydraulic shock absorber 9. The bottom of the hydraulic shock absorber 9 is installed with the top of the mounting column 2.

[0032] As a technical optimization of this utility model, by setting the mounting groove 8 and the hydraulic shock absorber 9, the mounting groove 8 at the top of the elastic ring 41 and the hydraulic shock absorber 9 at the bottom of the clamping plate 54 can convert the vibration energy into heat energy by utilizing the damping effect of hydraulic oil when subjected to vibration, thereby further enhancing the shock absorption and buffering capacity.

[0033] refer to Figure 1 The electric push rod 51 is electrically connected to the controller 10 via a wire. The controller 10 is mounted on the front of the mounting column 2 and is electrically connected to the vibration sensor 42 via a wire.

[0034] As a technical optimization of this utility model, by setting up a controller 10, when the vibration sensor 42 detects vibration, it can transmit the signal to the controller 10. The controller 10 controls the electric push rod 51 to move according to the preset program, thereby realizing intelligent vibration reduction and improving the timeliness and accuracy of responding to vibration.

[0035] refer to Figure 1 A limiting ring 11 is installed on the outside of the mounting column 2. The limiting ring 11 is located outside the elastic ring 41. A movable groove 12 is provided on the outside of the limiting ring 11, and the universal shaft 44 is located inside the movable groove 12.

[0036] As a technical optimization of this utility model, by setting a limiting ring 11 and a movable groove 12, the limiting ring 11 on the outside of the mounting column 2 plays a limiting role on the mounting device body 1, avoiding the situation where the mounting device body 1 shakes and the shock absorption effect is poor. At the same time, the movable groove 12 can ensure that the universal shaft 44 moves within the specified range, preventing the shock absorption effect from being affected or the device from being damaged due to excessive movement of the universal shaft 44.

[0037] refer to Figure 3 A slider 13 is installed on the outer side of the movable plate 6, and a groove 14 is provided on the inner wall of the limiting ring 11. The surface of the slider 13 is located inside the groove 14.

[0038] As a technical optimization of this utility model, by setting slider 13 and groove 14, slider 13 on the outer side of movable plate 6 cooperates with groove 14 on inner wall of limiting ring 11, which plays a guiding and limiting role during the movement of movable plate 6, making the movement of movable plate 6 more stable, avoiding the shaking of movable plate 6, and enhancing shock absorption performance.

[0039] The working principle and usage process of this utility model are as follows: When vibrations are generated during earthwork excavation, mechanical operations, etc., the elastic ring 41 initially buffers the vibration force, reducing its direct impact on the main body 1 of the installation device. At the same time, the vibration sensor 42 monitors the vibration in real time. Once the vibration force reaches a preset threshold, it immediately sends a signal to the controller 10. After receiving the signal, the controller 10 starts the electric push rod 51 according to the preset program. The output end of the electric push rod 51 pushes the moving column 53 to move in the connecting groove 52. The moving column 53 drives the pressure plate 54 to move downward, thereby adjusting the pressure on the elastic ring 41. In this way, it can adaptively adjust according to different degrees of vibration, ensuring stability even in complex vibration environments. During this process, the universal joint 44 can flexibly adjust the position of the connecting rod 45, driving the sand box 46 to move. The inertia and gravity of the sand box 46 are used to offset some of the vibration energy, further enhancing the shock absorption effect. The movable plate 6 provides support for the electric push rod 51. Provides stable support, and the rubber plate 7 at the top acts as a shock absorber between the movable plate 6 and the connecting plate 43, reducing the vibration force on the detection rod 3 and ensuring the stable operation of the detection rod 3. The mounting groove 8 at the top of the elastic ring 41 and the hydraulic shock absorber 9 at the bottom of the clamping plate 54 work together. When vibration occurs, the hydraulic shock absorber 9 uses the damping effect of hydraulic oil to convert the vibration energy into heat energy and dissipate it. The limiting ring 11 and the movable groove 12 on the outside of the mounting column 2, as well as the slider 13 on the outside of the movable plate 6 and the sliding groove 14 on the inner wall of the limiting ring 11, work together. The limiting ring 11 limits the body 1 of the installation device to prevent it from shaking and affecting the shock absorption effect. The movable groove 12 restricts the movement of the universal shaft 44 within a specified range to avoid damage to the device due to excessive movement of the universal shaft 44. The slider 13 and the sliding groove 14 cooperate to make the movable plate 6 more stable during movement, further improving the shock absorption performance of the device, achieving the shock absorption and buffering effect, and enhancing the use effect of the installation device.

[0040] In summary, this foundation pit displacement monitoring point deployment device, by setting up a detection buffer component 4 in conjunction with an adjustable shock-absorbing component 5 to dampen the vibration of the deployment device body 1 and the detection rod 3, solves the problem that existing deployment devices lack a shock-absorbing structure. This makes it possible for the monitoring point deployment device to be affected by vibrations and collisions during foundation pit construction due to factors such as earthwork excavation and mechanical operations, which can damage the stability of the device, cause inconvenience during use, and reduce the effectiveness of the deployment device.
