Description

Technical Field

[0001] This utility model relates to the field of rock mass monitoring technology, and in particular to a device for monitoring rock mass deformation in high-altitude areas. Background Technology

[0002] A dangerous rock mass refers to a large, isolated rock formation located on a steep slope. These rocks can range in size from large to isolated boulders. Vibrations or heavy rain can cause them to fall from steep slopes, and strong winds can sometimes blow unstable boulders off. Dangerous rock masses are potential landslide hazards.

[0003] Publication No. CN218238630U discloses an auxiliary device for monitoring cracks in unstable rock masses. The casing has a cavity, and a long sliding opening communicating with the cavity is provided on the side wall of the casing, extending along the length of the casing. A scale is fixed to the outer side wall of the casing along its length. One end of a sliding rod structure is slidably connected to the cavity, and the other end is rotatably connected to another support. A pointer adapted to the scale and slidably positioned within the long sliding opening is fixed to the sliding rod structure. This auxiliary device for monitoring cracks in unstable rock masses can adapt to various displacement directions or angles of unstable rock masses, exhibiting strong adaptability, simple structure, low cost, and practicality.

[0004] However, the above scheme has some drawbacks: although the above scheme is designed with joint bearings and connecting columns to adapt to displacement changes in multiple directions, the rock mass is mostly irregular in shape, and the fixed positions of the two base plates may not be on the same rock surface, which has great limitations. In addition, reading the scale requires people to climb up the rock mass to read it, which is inefficient and increases the danger. Utility Model Content

[0025] The following is combined with Figures 1-5 This invention describes a highland rock mass deformation monitoring device, comprising a monitoring component 100 and connecting components 200 located at both ends of the monitoring component 100. The connecting components 200 include a connecting seat and connecting ball joints 260, with the ball joints 260 ball-hinged to the connecting seat. The monitoring component 100 includes a tube body 110, a sliding rod 130, a displacement sensor 140, and an adjusting rod 150. The sliding rod 130 is slidably connected to the tube body 110, and the adjusting rod 150 is telescopically connected to the sliding rod 130. One connecting ball joint 260 is fixedly connected to the tube body 110, and the other connecting ball joint 260 is fixedly connected to the adjusting rod 150. The adjusting rod 150 extends and retracts on the sliding rod 130 to adjust the distance between the two connecting ball joints 260. The displacement sensor 140 is connected between the tube body 110 and the sliding rod 130 to monitor the relative displacement between them.

[0026] Specifically, such as Figure 1 , Figure 2 As shown, two connecting seats are anchored to the rock mass on both sides of the crack, and the monitoring component 100 is located between the two connecting seats. The pipe body 110 is connected to one connecting seat via a ball joint 260, and the adjusting rod 150 is connected to the other connecting seat via another ball joint 260. The initial length of the monitoring component 100 is adjusted by extending and retracting the adjusting rod 150, and the displacement sensor 140 senses and monitors the sliding displacement distance of the sliding rod 130. When using the deformation monitoring device, the relative displacement of the rock mass causes a change in the center distance between the two ball joints, causing the adjusting rod 150 and the sliding rod 130 to slide axially relative to the pipe body 110 together. The displacement sensor 140 directly measures this sliding amount, which is the opening, closing, or displacement of the rock mass. The multi-directional rotation of the ball joint connection improves the adaptability to rock mass monitoring. The displacement is monitored by the displacement sensor 140, eliminating the need for manual climbing to read the scale, ensuring safety and real-time monitoring.

[0027] It should be noted that the displacement sensor 140 is a conventional instrument, and its working method and principle are common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0028] Furthermore, the outer wall of the sliding rod 130 is provided with a first limiting plane 131, and the inner wall of the tube 110 is provided with a second limiting plane 112. The first limiting plane 131 and the second limiting plane 112 are in contact to restrict the relative rotation between the sliding rod 130 and the tube 110.

[0029] Specifically, such as Figure 1 , Figure 2As shown, the second limiting plane 112 on the inner wall of the tube 110 fits against the first limiting plane 131, guiding the axial sliding of the sliding rod 130 while restricting the relative rotation between the sliding rod 130 and the tube 110.

[0030] Furthermore, a scale line 132 is provided on the first limiting plane 131.

[0031] Specifically, such as Figure 2 As shown, the scale line 132 is set to help record the initial installation length during the initial installation, which is helpful for comparison when acquiring data from the displacement sensor 140 later.

[0032] Furthermore, the tube body 110 has a wire hole on its side wall for the wire of the displacement sensor 140 to pass through. A sealing tube that passes through the wire hole is fitted on the wire of the displacement sensor 140, and the sealing tube fills the gap between the wire hole and the wire of the displacement sensor 140.

[0033] Specifically, such as Figure 2 As shown, the circuit of the displacement sensor 140 is wrapped with a sealing tube. The circuit of the displacement sensor 140 and the sealing tube pass through the side wall of the tube body 110 together. The sealing tube fills the gap between the wire hole and the circuit of the displacement sensor 140, ensuring the sealing effect at the wire hole, preventing rainwater from seeping in, and improving the sealing performance.

[0034] In one specific embodiment, the end of the adjusting rod 150 away from the connecting ball head 260 is threadedly connected to the sliding rod 130.

[0035] Specifically, such as Figure 2 As shown, the adjusting rod 150 includes a threaded rod 151 and a connecting rod 152. The threaded rod 151 is fixedly connected to the connecting rod 152 and threadedly connected to the sliding rod 130. A threaded groove 133 is provided inside the sliding rod 130, and the threaded rod 151 is threadedly connected to the threaded groove 133. The connecting rod 152 is fixedly connected to the connecting ball head 260. By setting the threaded rod 151 and the connecting rod 152, the adjusting rod 150 can be rotated to move axially via the threaded connection, adjusting the length of the adjusting rod 150 extending beyond the sliding rod 130. This allows for the adjustment of the initial length of the telescopic monitoring component 100 through the adjustment of the adjusting rod 150.

[0036] In another alternative embodiment, the end of the adjusting rod 150 away from the connecting ball head 260 is inserted into the sliding rod 130, and the side wall of the sliding rod 130 is threaded with a set screw 134.

[0037] Specifically, such as Figure 5As shown, a connecting slide hole is provided inside the sliding rod 130 for the adjusting rod 150 to be inserted and slid. The end of the adjusting rod 150 away from the connecting ball head 260 is inserted into the connecting slide hole, and a set screw 134 is threadedly connected to the side wall of the sliding rod 130. By sliding the adjusting rod 150 in the connecting slide hole, the end of the set screw 134 protrudes from the connecting slide hole. By tightening the set screw 134, the end of the set screw 134 is pressed against the outer wall of the adjusting rod 150, thereby achieving relative fixation between the adjusting rod 150 and the sliding rod 130.

[0038] Furthermore, the connecting assembly 200 also includes a connecting block 261, which is fixedly connected to the connecting ball head 260. The tube body 110 and the adjusting rod 150 are respectively fixedly connected to the connecting ball head 260 through the connecting block 261. The connecting seat is provided with a slot 241 for the connecting block 261 to be rotated and inserted.

[0039] Specifically, such as Figure 2 As shown, connecting blocks 261 are fixedly connected to the ends of both the pipe body 110 and the adjusting rod 150. One connecting block 261 is fixedly connected to the adjusting rod 150 and the connecting ball head 260 located at the end of the adjusting rod 150, and the other connecting block 261 is fixedly connected to the pipe body 110 and the connecting ball head 260 located at the end of the pipe body 110, so that each end of the adjusting assembly is fixedly connected to a connecting ball head 260. The connecting blocks 261 and the slots 241 are adapted to each other. By setting the connecting blocks 261 and the slots 241, when it is necessary to rotate the ball head to adjust the position, such as when the sliding rod 130 is parallel to the rock mass or at an acute angle to the rock mass, the connecting blocks 261 can be rotated and inserted into the slots 241, increasing the adjustment angle while restricting the rotation of the connecting ball head 260, thus improving the stability of the connection.

[0040] Furthermore, the connecting seat includes a mounting base plate 210, an arc-shaped ball seat 240, and a connecting column 220. One end of the connecting column 220 is fixedly connected to the bottom of the arc-shaped ball seat 240, and the other end of the connecting column 220 is rotatably connected to the mounting base plate 210. The connecting ball head 260 is ball-hinged to the arc-shaped ball seat 240.

[0041] Specifically, such as Figure 1 , Figure 3 As shown, the ball joint 260 is hinged within the arc-shaped ball seat 240, the upper end of the connecting column 220 is fixed to the arc-shaped ball seat 240, and the lower end of the connecting column 220 is rotatably connected to the mounting base plate 210, so that the arc-shaped ball seat 240 can rotate around the axis of the connecting column 220, ensuring that the rock mass deformation monitoring device can adapt to the non-directional deformation of the rock mass after installation, and avoiding the device from being twisted off.

[0042] Furthermore, the mounting base plate 210 has a rotating hole for the connecting post 220 to pass through, and a circular plate 221 is fixedly connected to one end of the connecting post 220 that extends out of the rotating hole. A circular groove 211 is provided at the bottom of the mounting base plate 210 for the circular plate 221 to be inserted into and rotated.

[0043] Specifically, such as Figure 3 , Figure 4 As shown, a circular groove 211 is formed at the bottom of the mounting base plate 210, and the circular plate 221 at the lower end of the connecting column 220 is embedded in the circular groove 211. After the mounting base plate 210 is fixed to the rock mass, the connecting column 220 can only rotate on the mounting base plate 210 and cannot be pulled out, forming a hidden rotating pair.

[0044] Furthermore, the mounting base plate 210 has multiple mounting holes 212. These mounting holes 212 are used to pass through bolts or screws and other fixing equipment to secure the rock mass.

[0045] In one specific implementation, the tube body 110, the sliding rod 130, and the mounting base plate 210 are all made of stainless steel.

[0046] The working principle of this high-altitude rock mass deformation monitoring device is as follows: During initial installation, when two mounting base plates 210 need to be installed on different rock surfaces, as shown in the figure, the arc-shaped ball seat 240 rotates relative to the connecting ball head 260. The arc-shaped ball seat 240 drives the connecting column 220 and the mounting base plate 210 to rotate together, so that the two mounting base plates 210 contact different rock surfaces respectively, thereby achieving the two mounting base plates 210 being fixedly installed on different rock surfaces. When the rock mass deforms, the sliding rod 130 and the pipe body 110 will slide against each other, and the sliding rod 130 will pull the displacement sensor 140, which monitors the rock mass deformation in real time. The data is transmitted to the back-end equipment through the displacement sensor 140, which is highly efficient and safe. Furthermore, when the two mounting base plates 210 are installed on different rock surfaces, the arc-shaped ball seat 240 and the connecting ball head 260 can rotate relative to each other. When the two mounting base plates 210 are installed on the same rock surface, the circular plate 221 rotates in the circular groove 211, so that the connecting column 220 can rotate relative to the mounting base plate 210, thereby greatly ensuring the ability to adapt to displacement or rotation caused by non-directional deformation of the rock mass and improving practicality.

[0047] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0048] 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.
