Description

Technical Field

[0001] This utility model relates to the technical field of ball bearing stabilizers, and in particular to a ball bearing stabilizer for monitoring ground settlement. Background Technology

[0002] A ground settlement monitoring beacon centralizer is a device used to ensure that monitoring beacons remain vertically stable during ground settlement monitoring. Utilizing a ball-bearing design, the centralizer effectively corrects beacon deviations in various directions through internally rotating balls, ensuring it remains vertical at all times. This design reduces friction and wear, improving the centralizer's durability and accuracy, thereby guaranteeing more accurate and reliable sensor measurements. In civil engineering, building construction, and geological disaster early warning systems, ball-bearing centralizers are of great significance for ensuring the accuracy of monitoring data and engineering safety.

[0003] Traditional ground settlement monitoring beacon uprights ensure the beacon remains vertical during ground settlement monitoring through physical support structures. Their working principle involves using rigid supports or fixing devices to secure the beacon to the foundation, preventing it from tilting or shifting. These support structures are typically made of robust materials and ensure the beacon's stability through direct contact and mechanical fixation. While this method can maintain the beacon's verticality to a certain extent, in environments with significant ground variations, the support structure may wear or loosen, affecting the accuracy of the monitoring data.

[0004] Traditional ball bearing centralizers for ground settlement monitoring typically employ an integrated design, with the number and layers of balls fixed during manufacturing. This prevents flexible adjustments after installation, limiting adaptability and making them unsuitable for scenarios requiring higher precision and stability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ball bearing stabilizer for ground settlement monitoring benchmarks, which aims to improve the problem that the balls in traditional ground settlement monitoring benchmark ball bearing stabilizers cannot be flexibly adjusted after installation, which limits the adjustment of the number and layers of balls, resulting in poor adaptability and the inability to provide sufficient support in scenarios requiring higher precision and stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ball-bearing centralizer for monitoring ground settlement, comprising a fixed ring, a threaded ring internally connected to the fixed ring, a ball bearing disposed inside the threaded ring, one side of the outer wall of the ball bearing disposed inside the fixed ring, a positioning hole formed in the inner wall of the fixed ring, a positioning rod fixedly connected to the outer wall of the fixed ring, a connecting assembly disposed in the inner wall of the fixed ring for connecting two fixed rings, a fixed post fitted to the inner wall of the fixed ring, a fixed plate fixedly connected to one end of the fixed post, a sliding post slidably connected inside the fixed post, a fixed plate fixedly connected to one end of the sliding post, and a fixing bolt 2 disposed inside both the fixed post and the sliding post, the outer wall of the fixing bolt 2 being threadedly connected to the inside of the fixed ring.

[0007] Furthermore, the connecting assembly includes a connector, the outer wall of which is fitted against the inner wall of the fixing ring, and a fixing bolt is provided inside the connector, the outer wall of which is threadedly connected to the inside of the fixing ring.

[0008] Furthermore, a marker is provided on the inner wall of the fixing ring, and a connector is fixedly connected to one end of the marker.

[0009] Furthermore, both the first and second fixing plates are rotatably connected to a rotating sleeve, and a connecting rod is fixedly connected to the inner wall of the rotating sleeve.

[0010] Furthermore, the outer wall of the connecting rod is slidably connected to the inside of the fixed plate, and a rotating plate is fixedly connected to one end of the connecting rod.

[0011] Furthermore, the rotating plate has a sliding groove inside, and the outer wall of the rotating plate is rotatably connected to the inside of the fixed plate.

[0012] Furthermore, a slider is slidably connected inside the rotating plate, and the outer wall of the slider is slidably connected inside the fixed plate. The slider is located on the outside of the marker.

[0013] Furthermore, an adhesive plate is fixedly connected to the outer wall of the slider, and the outer wall of the adhesive plate is attached to the outer wall of the marker.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the drive threaded ring firstly allows different numbers of balls to be installed inside the fixed ring. Then, the balls are positioned using positioning holes and positioning rods. Finally, the connecting parts, fixing bolts, fixing plate one, fixing plate two, fixing column, sliding column, and fixing bolt two are used to connect and fix the multiple layers of balls. This solves the problems that the balls cannot be flexibly adjusted after installation, which limits the adjustment of the number and layers of balls, resulting in poor adaptability and insufficient support. It achieves the goal of adjusting the number and layers of balls, adapting to different geological environments and engineering needs, improving the flexibility, accuracy, and reliability of monitoring, and achieving the best monitoring effect.

[0016] 2. In this utility model, the rotating sleeve is first driven to rotate the rotating plate in conjunction with the connecting rod. Then, the sliding groove and the slider drive the bonding plate to bond with the marker. By welding or bolting, it can adapt to markers of different sizes, significantly improving the versatility of the straightener and reducing the types and quantities of equipment required.

[0025] Specifically, firstly, the ball bearing 3 is placed on the inner wall of the threaded ring 2. Then, due to the threaded relationship between the threaded ring 2 and the fixed ring 1, the threaded ring 2 is rotated into the interior of the fixed ring 1, and the ball bearing 3 is then installed inside the fixed ring 1. This process can be adjusted according to actual needs. Next, the positioning rod 5 on one side of one of the fixed rings 1 is inserted into the pre-set positioning hole 4 inside another fixed ring 1 to achieve positioning, thereby adjusting and positioning among multiple fixed rings 1. Due to the threaded relationship between the fixing bolt 7 and the fixed ring 1, the connecting piece 6 is used to connect the fixed ring 1 to the fixed ring 1. The rings 1 are fixed together, and then the fixing ring 1 is sleeved on the outer wall of the fixing column 10. Then the sliding column 11 is inserted into the interior of the fixing column 10, so that the fixing plate 1 8 and the fixing plate 2 9 wrap and fix the multiple fixing rings 1. Due to the thread relationship between the fixing bolt 2 12 and the fixing ring 1, the fixing column 10 and the sliding column 11 fix the fixing ring 1, thereby achieving the effect of adjusting the number and layers of the balls 3. Finally, the assembled ball-type straightener slides on the inner wall of the protective pipe to straighten the marker 13, so that it is always in a vertical state, and the settlement is monitored through the marker 13.

[0026] Reference Figure 1 and Figure 4 The inner wall of the fixed ring 1 is provided with a marker 13. One end of the marker 13 is fixedly connected to a connector 14. The interiors of the first fixed plate 8 and the second fixed plate 9 are both rotatably connected to a rotating sleeve 15. The inner wall of the rotating sleeve 15 is fixedly connected to a connecting rod 16. The outer wall of the connecting rod 16 is slidably connected to the interior of the first fixed plate 8. One end of the connecting rod 16 is fixedly connected to a rotating plate 17. The interior of the rotating plate 17 is provided with a sliding groove 18. The outer wall of the rotating plate 17 is rotatably connected to the interior of the first fixed plate 8. The interior of the rotating plate 17 is slidably connected to a slider 19. The outer wall of the slider 19 is slidably connected to the interior of the first fixed plate 8. The slider 19 is located on the outside of the marker 13. The outer wall of the slider 19 is fixedly connected to a bonding plate 20. The outer wall of the bonding plate 20 is bonded to the outer wall of the marker 13.

[0027] Specifically, the drive rotating sleeve 15 rotates inside the fixed plate 8, and then the connecting rod 16 drives the rotating plate 17 to rotate inside the fixed plate 8. Due to the pre-set sliding groove 18 inside the rotating plate 17, multiple sliders 19 slide inside the fixed plate 8 as the rotating plate 17 rotates, thereby driving the bonding plate 20 to bond with the ball 3. Finally, the connection is achieved by welding or bolting, so as to achieve a stable connection for different sized markers 13.

[0028] Working principle: When the ball bearing stabilizer for monitoring ground settlement is needed, first place the ball bearing 3 on the inner wall of the threaded ring 2. Using the thread relationship between the threaded ring 2 and the fixed ring 1, rotate the threaded ring 2 into the fixed ring 1 to install the ball bearing 3. Adjust the number of ball bearing 3 as needed. Then, insert the positioning rod 5 on one side of one fixed ring 1 into the preset positioning hole 4 inside another fixed ring 1 to achieve adjustment and positioning between multiple fixed rings 1. Use the fixing bolt 1 7 with the connector 6 to fix the fixed rings 1 and the fixed ring 1. Sleeve the fixed ring 1 on the outer wall of the fixed column 10 and insert the sliding column 11 for fixation. Fixing plate 1 8 and fixing plate 2 9 wrap and fix multiple fixed rings 1 and fix them with fixing bolt 2 12.

[0029] In addition, the drive rotating sleeve 15 rotates within the fixed plate 8, the connecting rod 16 drives the rotating plate 17 to rotate, the internal groove 18 of the rotating plate 17 causes the slider 19 to slide, driving the bonding plate 20 to bond with the ball 3, and the connection is achieved by welding bolts, thus realizing a stable connection of the standard rods 13 of different sizes.

[0030] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
