Description

Technical Field

[0001] The utility model relates to the technical field of support adjustment of mine convergence meters, and particularly relates to a support adjustment frame for surrounding rock deformation convergence meters. Background Art

[0002] A surrounding rock deformation convergence meter is an instrument used to monitor the tiny changes in the distance between any two points in any direction around the perimeter of the surrounding rock of underground mine projects. By measuring these tiny changes, it can be used to evaluate the stability of the project, that is, to determine whether the engineering structure is in a safe and stable state. At the same time, these data can also help researchers understand the deformation development law of the surrounding rock and support of the project, which is crucial for understanding the behavior characteristics of the engineering structure in the underground environment.

[0003] The existing observation methods usually use the "cross" measurement method to observe the shrinkage of the roadway. One person holds the measuring gun and the other person takes the reading. However, there are many set points in the roadway, and the workload is large. Each measurement requires the cooperation of two to three people, resulting in a high labor cost.

[0004] Therefore, the existing technology needs to be further developed. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies and provide a support adjustment frame for surrounding rock deformation convergence meters to solve the technical problems that multiple people are required to cooperate during the measurement process of the surrounding rock deformation convergence meter in the related technology, resulting in low measurement efficiency and high labor cost.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions: A support adjustment frame for surrounding rock deformation convergence meters is provided, including: a fixed frame for placing the convergence meter; an adjusting member connected to the fixed frame and movably arranged on the fixed frame. One end of the convergence meter is located on the fixed frame, and the other end of the convergence meter is supported by the adjusting member. When the adjusting member moves on the fixed frame, the placement angle of the convergence meter also changes; a connecting component, one end of which is detachably connected to the fixed frame, and the other end of which is connected to the bolt in the surrounding rock.

[0007] Furthermore, a first fixing plate and a second fixing plate are arranged on the fixed frame. The first fixing plate and the second fixing plate are connected to each other. The adjusting member is connected to the first fixing plate and moves on the first fixing plate to change the placement angle of the convergence meter; the connecting component is clamped to the second fixing plate, thereby fixing the support adjustment frame to the bolt in the surrounding rock.

[0008] Furthermore, a through hole is arranged on the first fixing plate. The adjusting member is a bolt that passes through the through hole. When the bolt moves in the through hole, the distance from the end of the bolt to the first fixing plate changes, thereby adjusting the placement angle of the convergence meter located at the end of the bolt.

[0009] Furthermore, there are at least two perforations, and the perforations are arranged at intervals along the length direction of the convergence meter. There are at least two adjusting members, and each adjusting member is arranged corresponding to each perforation one by one.

[0010] Furthermore, there is an included angle between the first fixing plate and the second fixing plate, and the convergence meter is placed in the gap of the included angle.

[0011] Furthermore, the first fixing plate is perpendicular to the second fixing plate.

[0012] Furthermore, a clamping component is arranged on the side of the second fixing plate away from the first fixing plate. There is a clamping cavity between the clamping component and the second fixing plate. A clamping plate is arranged on the connecting component, and the clamping plate enters the clamping cavity to connect the connecting component with the fixing frame.

[0013] Furthermore, one end of the connecting component away from the clamping plate is detachably connected to the bolt, and the connecting component is threadedly connected to the bolt.

[0014] Furthermore, the fixing frame further includes a stop baffle, and the stop baffle is arranged on one side of the first fixing plate. When the inclination amplitude of the convergence meter relative to the first fixing plate is large, the stop baffle is used to prevent the convergence meter from falling off the fixing frame.

[0015] Furthermore, the surrounding rock deformation convergence meter support and adjustment frame further includes a reflector, and the reflector is fixed on the surface of the surrounding rock. The reflector is used to reflect laser light. The reflector is arranged opposite to the fixing frame, and the convergence meter on the fixing frame realizes precise measurement by receiving the reflected laser light from the reflector.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] According to the embodiment of the present utility model, a surrounding rock deformation convergence instrument support adjusting frame is provided. Please refer to Figures 1 to 6, including: a fixing frame 1 for placing a convergence meter 2; an adjusting member 3 connected to the fixing frame 1 and movably arranged on the fixing frame 1. One end of the convergence meter 2 is located on the fixing frame 1, and the other end of the convergence meter 2 is supported by the adjusting member 3. When the adjusting member 3 moves on the fixing frame 1, the placement angle of the convergence meter 2 also changes accordingly; a connecting assembly 4, one end of the connecting assembly 4 is detachably connected to the fixing frame 1, and the other end of the connecting assembly 4 is connected to a bolt 5 in the surrounding rock. The connecting assembly 4 firmly fixes the support adjusting frame to the bolt 5 in the surrounding rock, and the connecting assembly 4 is detachable from the fixing frame 1, which is beneficial to moving the fixing frame 1 at any time. The adjusting member 3 supports the convergence meter 2. Through the movable design of the adjusting member 3 on the fixing frame 1, the user can easily adjust the placement angle of the convergence meter 2 to adapt to different measurement environments and requirements. This not only makes the measurement process of the surrounding rock deformation convergence meter no longer require the cooperation of multiple people and can be operated by a single person, greatly improving the measurement efficiency; the measurement process is simplified, and the manpower requirement is also reduced, thus reducing the labor cost of the measurement work. The support adjusting frame of the surrounding rock deformation convergence meter in this embodiment solves the technical problems of the need for the cooperation of multiple people, low measurement efficiency, and high labor cost in the measurement process of the surrounding rock deformation convergence meter in the related art.

[0030] Refer to Figure 2 , for the support adjusting frame of the surrounding rock deformation convergence meter in this embodiment, a first fixing plate 11 and a second fixing plate 12 are arranged on the fixing frame 1. The first fixing plate 11 and the second fixing plate 12 are connected to each other. The adjusting member 3 is connected to the first fixing plate 11 and moves on the first fixing plate 11 to change the placement angle of the convergence meter 2; the connecting assembly 4 is clamped with the second fixing plate 12, thereby fixing the support adjusting frame to the bolt 5 in the surrounding rock. The first fixing plate 11 and the second fixing plate 12 are connected to each other to form the main structure of the support adjusting frame. The adjusting member 3 is connected to the first fixing plate 11 and moves on it to change the placement angle of the convergence meter 2. This design makes the angle adjustment simple and accurate, and the user can easily adjust the angle of the convergence meter according to the measurement requirements, thereby improving the accuracy and reliability of the measurement. The connecting assembly 4 is clamped with the second fixing plate 12, enabling the support adjusting frame to be quickly and conveniently fixed to the bolt 5 in the surrounding rock. This installation method not only saves time but also reduces the requirements for the operator's skills.

[0031] Refer to Figure 3, for the surrounding rock deformation convergence instrument support adjusting frame of this embodiment, a through hole 111 is provided on the first fixing plate 11, the adjusting member 3 is a bolt 31, the bolt 31 is arranged through the through hole 111, when the bolt 31 moves in the through hole 111, the distance from the end of the bolt 31 to the first fixing plate 11 is changed, so as to adjust the placement angle of the convergence instrument 2 located at the end of the bolt 31. The movement of the bolt 31 in the through hole 111 can very precisely control the distance from its end to the first fixing plate 11, and further realize the fine adjustment of the placement angle of the convergence instrument 2. The user only needs to rotate the bolt 31 to realize the angle adjustment, without complex tools or operation steps.

[0032] Refer to Figure 3 , Figure 4 and Figure 5 , for the surrounding rock deformation convergence instrument support adjusting frame of this embodiment, there are at least two through holes 111, and the through holes 111 are arranged at intervals along the length direction of the convergence instrument 2. There are at least two adjusting members 3, and each adjusting member 3 is arranged corresponding to each through hole 111. Through multiple support points distributed in the length direction of the convergence instrument 2, the shaking and instability phenomena caused by single-point support can be effectively reduced, and the horizontal angle direction of the convergence instrument 2 can be more precisely fine-tuned, thereby improving the accuracy and reliability of the measurement.

[0033] Refer to Figure 2 , for the surrounding rock deformation convergence instrument support adjusting frame of this embodiment, there is an included angle between the first fixing plate 11 and the second fixing plate 12, and the convergence instrument 2 is placed in the gap of the included angle.

[0034] Refer to Figure 2 , for the surrounding rock deformation convergence instrument support adjusting frame of this embodiment, the first fixing plate 11 is perpendicular to the second fixing plate 12, so as to provide more accommodation space for the convergence instrument 2.

[0035] Refer to Figure 2 , for the surrounding rock deformation convergence instrument support adjusting frame of this embodiment, a clamping component 13 is arranged on the side of the second fixing plate 12 away from the first fixing plate 11. A clamping cavity 14 is arranged between the clamping component 13 and the second fixing plate 12. A clamping plate 41 is arranged on the connecting component 4, and the clamping plate 41 enters the clamping cavity 14 to connect the connecting component 4 with the fixing frame 1. The operator only needs to align the clamping plate 41 with the clamping cavity 14 and gently push it in to complete the connection; similarly, when disassembling, only need to pull the clamping plate 41 out of the clamping cavity 14. This characteristic of quick connection and disassembly greatly improves the work efficiency and reduces the time required for installation and disassembly.

The stop plate 15 is arranged on one side of the first fixing plate 11. When the inclination of the convergence instrument 2 relative to the first fixing plate 11 is relatively large, the stop plate 15 is used to prevent the convergence instrument 2 from falling off the fixing frame 1. During the measurement process, the convergence instrument 2 may be inclined to a certain extent due to the influence of surrounding rock deformation, vibration or other external factors. The presence of the stop plate 15 provides an additional support point for the convergence instrument 2, effectively preventing the convergence instrument 2 from falling off the fixing frame 1 in case of inclination or accident.

[0038] Refer to Figure 6 For the support adjustment frame of the surrounding rock deformation convergence instrument in this embodiment, the support adjustment frame of the surrounding rock deformation convergence instrument further includes a reflector 6. The reflector 6 is fixed on the surface of the surrounding rock. The reflector 6 is used to reflect laser light. The reflector 6 is arranged opposite to the fixing frame 1. The convergence instrument 2 on the fixing frame 1 realizes precise measurement by receiving the reflected laser light from the reflector 6. The reflector 6 can accurately reflect the laser beam, reduce the scattering and attenuation of light during the propagation process, and make the signal received by the convergence instrument 2 clearer and more stable. This helps to reduce measurement errors and improve the accuracy and precision of the measurement.
