Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, specifically a deformation monitoring point protection device. Background Technology

[0002] In numerous fields such as civil engineering, geological disaster prevention, water conservancy projects, and transportation infrastructure operation and maintenance, deformation monitoring is a crucial link in ensuring the safety of engineering structures, preventing disasters, and assessing the stability of projects. As the core carrier for obtaining deformation data of structures or geological bodies, the location and stability of deformation monitoring points directly determine the accuracy and reliability of the monitoring data. Accurate monitoring data is an important basis for engineers to judge the health status of structures, formulate operation and maintenance strategies, and provide early warnings of disaster risks.

[0003] However, in actual engineering projects, deformation monitoring points are often directly exposed to complex and changing natural environments or high-intensity engineering work environments, making them highly susceptible to damage from various factors. To address this issue, current engineering practices commonly employ protective devices to physically protect the monitoring points. These protective devices reduce the direct impact of external forces and slow down environmental erosion by wrapping, isolating, or reinforcing the monitoring points, thereby ensuring the long-term reliability of the monitoring points. However, during actual installation, a specific safe distance must be maintained between the protective device and the deformation monitoring point. Currently, this distance control mainly relies on manual measurement by workers using simple measuring tools such as steel rulers and vernier calipers, or pre-positioning of holes by fitting a positioning template to the substrate; only after the position is confirmed to meet the requirements can subsequent procedures such as bolt fixing and bracket installation of the protective device be carried out. This method is not only inefficient but also prone to distance deviations due to individual operational differences; based on this, this application proposes a deformation monitoring point protection device.

[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] This utility model provides an embodiment: Please refer to Figures 1-8 A deformation monitoring point protection device includes several protective side plates. Two adjacent protective side plates are connected by a transition plate 3. The several protective side plates are combined in a modular manner to form an isolation frame for protecting the deformation monitoring point. When in use, the size of the isolation frame can be flexibly adjusted according to the different deployment scenarios of the monitoring points, so that the device can adapt to a variety of deformation monitoring points, improve the adaptability of the application, and can be disassembled and carried during transportation and on-site installation, improving the convenience of use in complex environments such as high altitudes and confined spaces.

[0017] The protective side panel has a split structure, including a central positioning post and an extension post 2 that is detachably connected to the central positioning post. The central positioning post includes a fixed post 1, the extension post 2 is detachably connected to the fixed post 1, and the adapter plate 3 is detachably connected to the extension post 2.

[0018] The adapter plate 3 is L-shaped, with hollow cavities at both ends and on one side of the extension column 2. A telescopic belt structure is installed within each hollow cavity. This structure includes a movable rod 18, a coil spring 19, and a fixing belt 4, all movably connected to the bottom of the hollow cavity. A coil spring 19 is attached to the outer ring of the movable rod 18. One end of the coil spring 19 is connected to the movable rod 18, and the other end is connected to the fixing belt 4. The fixing belt 4 is spirally wound around the coil spring 19, forming a "contracted energy storage" state. An opening is provided on the cavity wall of the hollow cavity. The other end of the fixing belt 4 extends through this opening to the outside of the hollow cavity and is fixedly connected to a fixing insert 17. The fixing belt 4 is movably connected to the opening, and the size of the fixing insert 17 is larger than the size of the opening. This prevents the fixing belt 4 from completely retracting into the hollow cavity when excessively pulled, and also facilitates gripping and operation by the operator. The size of the fixing insert 17 can be set according to requirements and is not limited here.

[0019] With the telescopic belt structure, when the user holds the fixed insert 17 and pulls the fixed belt 4 outward, the coil spring 19 is gradually stretched and stores energy as the movable rod 18 rotates. The exposed length of the fixed belt 4 can be increased. When the restriction on the fixed belt 4 is lifted, the fixed belt 4 can automatically retract into the hollow cavity under the action of the rebound force of the coil spring 19, and the fixed belt 4 is rewound onto the coil spring 19.

[0020] On the other side of the extension column 2 and on both sides of the fixed column 1, there are slots 9 that are adapted to the fixing insert 17. When the fixing insert 17 is inserted into the slot 9, the exposed length of the fixing strap 4 can be fixed.

[0021] As described above, the telescopic belt structure allows for rapid assembly and disassembly of the extension column 2 and the hollow positioning column or adapter plate 3, simplifying the operation process and significantly improving the assembly and disassembly efficiency of this device, making it particularly suitable for batch installations or subsequent maintenance scenarios. Furthermore, users can adjust the distance between the extension column 2 and the hollow positioning column or adapter plate 3 as needed, enabling the device to adapt to various requirements and enhancing the applicability of this application.

[0022] The outer side of the fixing strip 4 is equipped with a reflective strip. The reflective strip can improve the warning effect of the device at night or in low light environment. It can also help users quickly locate the device in night or in open areas. The reflective signal of the reflective strip can quickly confirm whether the device is intact, thus improving the efficiency and safety of night inspection.

[0023] A groove 5 is provided in the middle of the inner side of the fixed column 1. A distance fixing component is movably connected to the bottom end of the groove 5. A rotating shaft 14 is movably connected to the bottom end of the groove 5. The distance fixing component includes a first distance fixing plate 6 connected to the rotating shaft 14. A second distance fixing plate 7 is movably connected to the inner cavity of the first distance fixing plate 6. Both the first distance fixing plate 6 and the second distance fixing plate 7 are provided with scale lines 8 on their tops. The bottom of the second distance fixing plate 7 is flush with the bottom of the first distance fixing plate 6. There is damping between the first distance fixing plate 6 and the second distance fixing plate 7. Under the action of external force, the second distance fixing plate 7 can move in the inner cavity of the first distance fixing plate 6. When the external force is released, the position of the second distance fixing plate 7 can remain unchanged, which facilitates the use of the distance fixing component.

[0024] As described above, the distance fixing component has a telescopic function, and when the distance fixing component is in the extended state, both ends of the distance fixing component are in the same plane, which improves the stability of the distance fixing component and avoids distance measurement deviation caused by the height difference of the plate. It ensures that the distance fixing component can achieve distance calibration with a unified reference plane regardless of its working state.

[0025] When the distance-fixing component is in a horizontal state, the vertical plane where the 0 mark of the scale line 8 set on the first distance-fixing plate 6 is located is flush with the inner side wall of the fixed column 1. The length of the distance-fixing component can accurately reflect the distance between the fixed column 1 and the deformation monitoring point, eliminate measurement deviation, and improve the efficiency of determining the position of the protective side plate.

[0026] A power chamber is provided on the side wall of the fixed column 1. A driven sprocket 20 is movably connected to the bottom end of the power chamber. The driven sprocket 20 is connected to the distance fixing component through a rotating shaft 14. A driving sprocket 16 is movably connected to the top end of the power chamber. The driven sprocket 20 and the driving sprocket 16 are connected by a synchronous chain 15. A slot 10 is provided at the top end of the power chamber. A handle 12 is movably connected to the inner cavity of the slot 10. One end of the handle 12 is located on the outside of the fixed column 1 and is movably connected to a fixing screw 13. A fixing hole 11 adapted to the fixing screw 13 is provided on one side of the bottom end of the slot 10. The other end of the handle 12 is connected to one side of the top end of the synchronous chain 15, and the handle 12 is connected to the vertical section of the synchronous chain 15.

[0027] As described above, the user can use the handle 12 to drive the synchronous chain 15 to rotate. When the synchronous chain 15 rotates, it can drive the rotating shaft 14 to rotate through the driven sprocket 20. The rotating shaft 14 drives the distance fixing component to rotate, realizing the conversion between the distance fixing component and the horizontal and vertical states. When the distance fixing component is in the vertical state, it is convenient to store the central positioning column and can avoid the distance fixing component affecting the deformation monitoring point when the device is in use.

[0028] When the distance fixing component is in a vertical position, the distance fixing component is located in the groove, and the fixing screw 13 is aligned with the fixing hole 11. The user inserts the fixing screw 13 into the fixing hole 11, and the fixing screw 13 can fix the position of the handle 12, thereby fixing the position of the distance fixing component.

[0029] In summary: When the user pulls the fixing screw 13 outward, the fixing screw 13 is separated from the fixing hole 11. After the handle 12 is unlocked, the user pushes the handle 12 upward until the handle 12 is tightly fitted with the top of the slot 10. During the movement of the handle 12, the synchronous chain 15 is driven to rotate. The synchronous chain 15 drives the driven sprocket 20 to rotate. The driven sprocket 20 drives the distance fixing component to rotate through the rotating shaft 14. Finally, the distance fixing component is transformed from a vertical storage state to a horizontal working state, completing the unfolding action.

[0030] After unfolding, the user adjusts the length of the distance-fixing component according to the preset safe distance between the protective device and the deformation monitoring point, until the length value displayed on the scale line of the distance-fixing component is exactly consistent with the distance that the fixed column 1 needs to maintain between the deformation monitoring point and the fixed column 1. The user precisely overlaps the end of the distance-fixing component away from the fixed column 1 with the edge of the deformation monitoring point area. The position of the fixed column 1 at this time is the reference installation position for the subsequent protective side plate, and positioning can be completed without additional measuring tools.

[0031] After determining the position of the fixed column 1, the user securely fixes it to the base that can deform synchronously with the deformation monitoring point using bolts and other fasteners. The distance between the extension column 2 and the fixed column 1 is adjusted, and the extension column 2 and the fixed column 1 are ensured to be on the same straight line. After the position of the extension column 2 is calibrated, the position of the extension column 2 is fixed, and the extension column 2 is connected to the fixed column 1 using the fixing strap 4 to complete the installation of a single set of protective side panels.

[0032] The position of the fixed adapter plate 3 is used to connect two adjacent protective side plates. Several protective side plates are combined in a modular manner to form an isolation frame for protecting deformation monitoring points, such as... Figure 2 As shown.
