Description

Technical Field

[0001] This utility model relates to the field of mining surveying technology, and more specifically, to a combined protection device for surface subsidence observation points in mining subsidence areas. Background Technology

[0002] Surface points are monitoring points buried on the ground surface to observe ground settlement. They are currently widely used in construction monitoring of uneven ground settlement around tunnels, foundation pits, and large buildings. However, existing surface point protection devices still have shortcomings in use. For example, during measurement, the connecting shaft of the protective cover plate of conventional surface point protection devices is often subjected to direct crushing by large construction machinery, resulting in plastic deformation. The protective cover is difficult to open, and it is difficult to replace parts after damage.

[0003] According to patent publication number CN218002523U, a combined protective device for surface subsidence observation points is disclosed. The device includes three parts: a protective cover plate, a lifting device, and a protective sleeve. The protective cover plate is provided with a numbering and engraving area and a stainless steel pull ring. This structure can avoid the problem of the protective cover plate being difficult to remove due to deformation caused by vehicle running over and impact. At the same time, it also makes the protective device as flush as possible with the ground, so as not to affect the passage of construction roads.

[0004] However, in actual use, such as when conducting surface subsidence observation in mining subsidence areas, the soil will cover and obscure the entire observation point due to mining work. During the observation, the observers need to locate the observation device, dig up the surface soil, and then conduct the observation, which reduces the work efficiency. Utility Model Content

The plurality of first limiting posts are fixedly connected to the protective shell. A first spring is provided on the outside of the plurality of first limiting posts.

At the same time, it can unfold the protective shell to expose the observation cone, improving the efficiency of observation and measurement.

The first wireless electric cylinder 9 can drive the connecting plate 8 and the entire protective shell 6 to move upward, so that the fan-shaped buffer shell 16 can be exposed to the soil, thereby improving the observation efficiency of the observers.

[0031] In some embodiments, according to Figure 3 , 4 As shown, a fixing plate 12 is hinged to the bottom of the second wireless electric cylinder 11. The fixing plate 12 is fixedly connected to the observation column 2. The output end of the second wireless electric cylinder 11 is hinged to the positioning frame 10. The positioning frame 10 is fixedly connected to the support column 5. The support column 5 is fixedly connected to the protective shell 6. The second wireless electric cylinder 11 can control the rotation of the positioning frame 10, thereby opening and closing the connecting plate 8 and the protective shell 6.

[0032] In some embodiments, according to Figure 2 As shown, the protective component includes a buffer arc plate 13 disposed on the outside of the protective shell 6. A plurality of first limiting posts 14 are provided on one side of the buffer arc plate 13. The plurality of first limiting posts 14 are fixedly connected to the protective shell 6. A first spring 15 is provided on the outside of the plurality of first limiting posts 14.

[0033] In some embodiments, according to Figure 2 As shown, one end of the first spring 15 is fixedly connected to the protective shell 6, and the other end of the first spring 15 is fixedly connected to the buffer arc plate 13. A fan-shaped buffer shell 16 is fixedly provided on the top of the buffer arc plate 13, and a second limiting post 17 is provided at the bottom of the fan-shaped buffer shell 16.

[0034] In some embodiments, according to Figure 1 , 2As shown, the second limiting post 17 is fixedly connected to the protective shell 6. A second spring 18 is provided on the outside of the second limiting post 17. One end of the second spring 18 is fixedly connected to the protective shell 6, and the other end of the second spring 18 is fixedly connected to the fan-shaped buffer shell 16. Multiple elastic protrusions 19 are fixedly provided on the outside of both the fan-shaped buffer shell 16 and the buffer arc plate 13. The multiple elastic protrusions 19 are evenly distributed on the outside of the fan-shaped buffer shell 16 and the buffer arc plate 13, which can better disperse the external impact force.

[0035] The working principle of this utility model is as follows: (refer to the appendix of the instruction manual) Figure 1-4 As shown, the present invention is fixed at a suitable observation position in the mining subsidence area, and the subsidence of the present invention is observed regularly. After a long period of mining, the surface is affected and subsides. During the mining process, the soil will cover the present invention.

[0036] When it is necessary to measure the surface settlement point, the first wireless electric cylinder 9 is activated to drive the connecting plate 8 to move upward. The connecting plate 8 then drives the protective shell 6 to move upward. When the protective shell 6 moves upward, it drives multiple movable ring shells 7 to slide and extend. When the connecting plate 8 moves, it drives the positioning frame 10 to move upward. At the same time, the second wireless electric cylinder 11 is activated to cooperate with the action of the first wireless electric cylinder 9, so that the protective shell 6 moves upward as a whole until the protective shell 6 is exposed on the soil surface.

[0037] Then, the second wireless electric cylinder 11 is activated to drive the positioning frame 10 to extend away from the observation column 2. The first wireless electric cylinder 9 is then activated to work in coordination, so that the positioning frame 10 drives the connecting plate 8 to move away from the observation column 2. The connecting plate 8 then drives the protective shell 6 to move synchronously. The protective shell 6 then drives the first spring 15 and the second spring 18 to move synchronously, thereby driving the buffer arc plate 13 and the fan-shaped buffer shell 16 to move synchronously until the observation cone 3 is exposed. The operator can then conduct settlement observation on the surface of the mining subsidence area. After the measurement is completed, the device is reset.

[0038] During periods when no observation points are being observed, the present invention will be subjected to external impact and pressure due to passing vehicles and accumulated soil coming into contact with it. These forces are first transmitted to the buffer arc plate 13 and the fan-shaped buffer shell 16 after passing through the elastic protrusion 19. Due to the buffering effect of the elastic protrusion 19, the impact and pressure on the buffer arc plate 13 and the fan-shaped buffer shell 16 are reduced before being transmitted to the first spring 15 and the second spring 18. After buffering, the impact and pressure will cause less damage to the inner protective shell 6, thus better protecting the observation column 2 and the observation cone 3.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
