Description

Technical Field

[0001] This utility model relates to the field of geostress detection technology, and in particular to a device for stabilizing and reinforcing geostress observation station instruments. Background Technology

[0002] In-situ stress monitoring is a technique that uses precision instruments to record the stress and deformation processes of rock masses. Typically, instruments are placed inside underground boreholes in the rock mass to collect stress change signals, thereby observing the characteristics of crustal stress changes; this is also known as borehole strain monitoring. In-situ stress is the force per unit area within the medium caused by rock deformation. Based on measured in-situ stress data, considering the influence of rock mass self-weight and tectonic stress, the initial in-situ stress field in the region is calculated, thus serving as a basis for construction and engineering design.

[0003] During long-term construction operations, the inventors discovered certain deficiencies in the existing technology for observation and use. For example, in a ground stress testing device with patent number CN221169555U, the observation equipment is positioned horizontally or vertically by rotating the column. However, during the adjustment of the column rotation, the column also serves as the support structure for the movement of the crossbar, and the two relatively arranged columns are fixed together by the crossbar. This results in poor stability of the crossbar for fixing the observation equipment, which can easily lead to increased errors in ground stress detection due to instability, affecting the quality of the operation. Therefore, there is an urgent need for a device to stabilize the observation instrument and solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a device for stabilizing and reinforcing instruments at geostress observation stations, in order to solve the problems existing in the prior art, thereby improving the stability of the observation instruments and ensuring the quality of the observation results.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figures 1-4 This utility model provides a device for stabilizing and reinforcing instruments at a geostress observation station, including a stress observation rod 1, and further comprising: Support frame 5; The base 2 is rotatably connected to the support frame 5. The support frame 5 is provided with a limiting component. The limiting end of the limiting component is connected to the base 2 to fix the base 2 relative to the support frame 5 in the horizontal or vertical direction. The movable plate 4 and the base 2 have a groove 3 along their length. The movable plate 4 slides in the groove 3. The top surface of the movable plate 4 has a groove. A pair of clamping plates 6 are arranged on opposite sides of the groove. A driving assembly is provided on the movable plate 4. The driving end of the driving assembly is connected to the pair of clamping plates 6 so that the pair of clamping plates 6 can move closer or further away from each other. The stress observation rod 1 is fixed between the pair of clamping plates 6. The stress observation rod 1 is parallel to the axis of the groove 3.

[0018] This utility model employs a frame structure support frame 5 to fix and support the stress observation rod 1. By setting a limiting component on the support frame 5, the base 2 is rotatably connected to the support frame 5, and can also be stably fixed to the support frame 5 in the horizontal or vertical direction through the limiting component. This facilitates the adjustment of the detection direction of the stress observation rod 1 and maintains the fixed stability of the stress observation rod 1 during observation operations. By sliding the movable plate 4 onto the base 2, and driving a pair of clamping plates 6 on the movable plate 4 to move closer to each other through a driving component, the stress observation rod 1 is clamped and fixed. Then, the stress observation rod 1 is moved along the axis of the slide groove 3, allowing the stress observation rod 1 to extend into the borehole to measure the ground stress. This achieves stable fixation of the observation instrument and ensures the accuracy of the observation structure.

[0019] Specifically, the stress observation rod 1 is constructed by a stainless steel pipe and together with conventional ground stress observation equipment such as packers, impression devices, and orientation devices. This is existing technology and will not be described in detail.

[0020] Furthermore, the limiting components include: A pair of adapter seats 7 are connected to each other on the top sides of the support frame 5, and the two sides of the base 2 are respectively fixed to the pair of adapter seats 7. Two limiting plates 8 are fixed to the top of the support frame 5. The limiting plates 8 are arranged one-to-one in the vertical direction above the adapter 7. The limiting plates 8 are provided with positioning pins 9. The side wall of the adapter 7 is provided with two positioning holes 10. The positioning pins 9 are respectively engaged with the two positioning holes 10 to fix the base 2 in the horizontal or vertical direction.

[0021] The adapter 7 is rotatably connected to the support frame 5 via a bearing (not shown in the figure), and the base 2 is fixed between a pair of adapters 7. The positioning pin 9 and positioning hole 10 on the limiting plate 8 are used to fix the base 2, thereby limiting and fixing the base 2. This allows the base 2 to be stably connected to the support frame 5 after the stress observation rod 1 is rotated to the horizontal or vertical direction, thus enhancing the fixation effect on the observation instrument during the observation process.

[0022] Furthermore, the included angle between the two positioning holes 10 on the same adapter 7 is 90°.

[0023] By setting an included angle of 90° between the two positioning holes 10, and using a positioning pin 9 to pass through the limiting plate 8 and be inserted into the positioning hole 10, the adapter 7, together with the base 2, is fixed to the support frame 5, and the positions of the two positioning holes 10 correspond exactly to the base 2 in the horizontal or vertical direction.

[0024] Furthermore, the driving components include: The servo motor 11 has a limiting groove on the bottom surface of the groove, and fixing blocks 12 are fixed to both ends of the limiting groove. The servo motor 11 is fixed in any one of the fixing blocks 12. The bidirectional lead screw 13 is connected between two fixed blocks 12. The output shaft of the servo motor 11 is coaxially fixed to the bidirectional lead screw 13. Two limit blocks 14 are symmetrically threaded along the center of the bidirectional lead screw 13. The limit blocks 14 slide in the limit groove and are fixed to the clamping plate 6 one by one.

[0025] The servo motor 11 drives the bidirectional lead screw 13 to rotate, causing the two limit blocks 14 to move closer or further apart, thereby causing a pair of clamping plates 6 to move closer together to clamp and fix the stress observation rod 1.

[0026] Furthermore, a padding layer 15 is fixed to the adjacent sides of a pair of clamping plates 6.

[0027] The pad 15 is made of sponge material to enhance the friction on the stress observation rod 1 and improve the fixation stability.

[0028] Furthermore, it also includes: A pair of servo cylinders 16 are started and stopped synchronously by an external control system. The pair of servo cylinders 16 are fixedly connected to opposite sides of the inner wall of the slide groove 3. The piston rod of the servo cylinder 16 is fixedly connected to a connecting plate 17. The two ends of the movable plate 4 are fixedly connected to the two connecting plates 17 respectively. The guide rod 18 is fixed to the bottom surface of the slide groove 3. The guide rod 18 is parallel to the axis of the slide groove 3. The bottom surface of the movable plate 4 is provided with a groove, and the guide rod 18 slides in contact with the inner wall of the groove.

[0029] A computer is used as an external control system to synchronously drive a pair of servo cylinders 16, causing the two connecting plates 17 to slide synchronously along the axis of the slide groove 3, which in turn drives the movable plate 4 and the stress observation rod 1 fixed on the movable plate 4 to move, so that the stress observation rod 1 can be inserted into the borehole to observe the ground stress.

[0030] Specifically, the connection end of the servo cylinder 16 and the piston rod is located in the middle of the slide groove 3, ensuring that the piston rod has sufficient extension and retraction to drive the movable plate 4 to move, so that the detection end of the stress observation rod 1 can effectively extend into the borehole.

[0031] Furthermore, the support frame 5 includes: A pair of oppositely arranged C-shaped plates 51; Two support rods 52 are set in the middle of the two sides of the wedge-shaped plate 51, and the two ends of any one support rod 52 are respectively fixed to a pair of wedge-shaped plates 51. The base 2 does not contact the support rod 52.

[0032] By using a pair of relatively arranged I-shaped plates 51, the support frame 5 forms four fixed legs, improving the stability of the base 2 and the movable plate 4. The pair of I-shaped plates 51 are fixed together by two support rods 52, forming a frame support structure. The support rods 52 are located in the middle of the I-shaped plates 51, which prevents the support rods 52 from contacting the base 2 during the rotation of the base 2, thus avoiding any resistance to the rotation of the base 2.

[0033] This utility model provides the working principle of a stabilization and reinforcement device for geostress observation station instruments: The four bottom ends of a pair of C-shaped plates 51 are fixed to the ground. The stress observation rod 1 is arranged horizontally or vertically according to the drilling position. The base 2 is rotated by pulling out the positioning pin 9. The base 2 is drilled accordingly, and then the stress observation rod 1 is inserted between a pair of clamping plates 6. The servo motor 11 is started to drive the pair of clamping plates 6 to clamp and fix the stress observation rod 1. At the same time, the positioning pin 9 passes through the limiting plate 8 and extends into the positioning hole 10, so that the base 2 fixes the stress observation rod 1 in the horizontal or vertical direction. The external control system drives a pair of servo cylinders 16 to start synchronously. The movable plate 4 is moved by the connecting plate 17 to extend the stress observation rod 1 relative to the support frame 5. After the stress observation rod 1 is inserted into the borehole, the ground stress observation operation can be carried out.
