Description

Technical Field

[0001] This invention relates to the field of monitoring technology, specifically to a prestressed steel structure anchoring device with monitoring function. Background Technology

[0002] The anchoring device for prestressed steel structures is one of the most critical and core components of a prestressed steel structure system. Its main function is to reliably anchor high-strength prestressing tendons (usually steel strands, wire bundles, or high-strength steel bars) to specific locations within the main steel structure, and to safely and effectively transfer the enormous tensile force generated by the prestressing tendons to the main structure. This allows the structure to achieve the required prestress state, improving its stress performance, such as increasing stiffness and load-bearing capacity, and reducing deformation.

[0003] The working principle of prestressed steel structure anchorage devices is to mechanically clamp or bond and lock the prestressing tendons, steel strands, steel wire bundles, or high-strength steel bars, converting the huge tensile force generated by tension into pressure or tension on the main steel structure, thereby actively improving the stress state of the structure. However, there are many problems in the application of prestressed steel structure anchorage devices. For example, huge forces will act on the connection points between the steel strands and the anchorage devices. The connection points between the steel strands and the anchorage devices are also subject to corrosion from rainwater and impurities, as well as wind pushing. In the prestressed steel structure anchorage system, many connection points between the steel strands and the anchorage devices are set at high altitudes, making it difficult to detect damage to the connection points in time, which affects safety.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Figures 1-12As shown, this invention provides a technical solution for a prestressed steel structure anchoring device with monitoring function, including a steel beam 1, a positioning component on the outside of the steel beam 1, an equipment box 16 on one side of the steel beam 1, a fixing box 20 inside the equipment box 16, a camera 22 inside the fixing box 20, a displacement control component between the fixing box 20 and the equipment box 16, an air storage component 25 and a height limit plate 46 on the top of the fixing box 20, a transmission component connected to one side of the air storage component 25, mounting brackets 33 fixedly connected to both sides of mounting bracket 27, two guide rods 34 passing through the mounting brackets 33, a spring-type telescopic rod 35 at the top of each of the two guide rods 34, the outer wall of the spring-type telescopic rod 35 fixedly connected to the top of the inner cavity of the equipment box 16, and the piston end of the spring-type telescopic rod 35 fixedly connected to the adjacent guide rod 34; a mounting bracket 47 fixedly connected between the bottom ends of the two guide rods 34, a weighting block 21 on the side of the fixing box 20 away from the steel beam 1, and two openings on the weighting block 21. Each inner groove 36 has a mounting bracket 37 corresponding to it. Multiple spring-loaded telescopic rods 47 are fixedly embedded in the weight-adding block 21. The piston end of each spring-loaded telescopic rod 47 is fixedly connected to the fixed box 20. The transmission assembly includes an air guide 28 fixedly connected to one side of the bottom of the air storage component 25, a telescopic tube 29 fixedly connected to one side of the air guide 28, an air guide 30 fixedly connected to one end of the telescopic tube 29, and an air guide 31 fixedly connected to one end of the air guide 30. The mounting bracket 27 contains... A pneumatic telescopic rod 32 is fixedly connected. One end of the air guide 31 is fixedly connected to the air inlet of the pneumatic telescopic rod 32. The piston end of the pneumatic telescopic rod 32 is fixedly connected to the fixed box 20. The telescopic tube 29 is fixedly connected to the mounting bracket 27. The bottom of the air storage component 25 is fixedly connected to the mounting bracket 24. Both T-shaped rods 26 are slidably connected to the mounting bracket 24. The outer wall of the air guide 28 is fixedly connected to the mounting bracket 24. The height limit plate 46 is set on the top of the air storage component 25 and fixedly connected to the inner wall of the equipment box 16.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple installation slots 2 are provided on the outer side of the steel beam 1, and multiple support wing plates 3 are fixedly connected to both sides of the steel beam 1. The upper part of the steel beam 1 is embedded and cast inside the main structure. The multiple installation slots 2 and multiple support wing plates 3 increase the force-bearing area and force direction between the steel beam 1 and the main structure, ensuring the firmness of the fixation between the steel beam 1 and the main structure.

[0022] The bottom of the steel beam 1 is on the outside of the steel structure. The bottom of the steel beam 1 has an installation groove 4. The bottom of the steel plate 15 installed inside the installation groove 4 is fixedly connected to the steel column 14. The bottom of the steel column 14 is fixedly connected to the wire rope 13, which connects to the prestressed node of the steel structure.

[0023] In the positioning assembly, the support frame 6 is located at the bottom of the inner cavity of the mounting groove 4. The base 5, which is rotatably sleeved on the outside of the support frame 6, is fixedly connected to the steel beam 1. The steel column 14 is aligned with the notch on the support frame 6 and the base 5, and the steel plate 15 is pushed into the steel beam 1 so that the bottom of the steel plate 15 is supported by the base 5 and the support frame 6. Then, the support frame 6 is rotated so that the notch on the support frame 6 is misaligned with the notch on the base 5. Then, the fixed side plate 2 9, which is fixedly connected to one side of the fixed side plate 8, is aligned with the notch on the base 5. The fixed side plate 8 is pushed into the mounting groove 4, and the fixed side plate 2 9 moves into the base 5 so that one end of the fixed side plate 2 9 fits against the support frame 6. Also, because one side of the fixed side plate 8 is fixed... The fixed connection has four fixed side plates 10. Two threaded grooves 11 are opened on the outer side of the fixed side plates 10. Multiple threaded grooves 7 are opened on the outer side of the steel beam 1 and the base 5. At this time, the threaded grooves 7 and the threaded grooves 11 correspond one-to-one. By rotating the bolt 12 through the corresponding threaded grooves 11 and 7, the fixed side plates 10 and the steel beam 1 or the fixed side plates 10 and the base 5 can be fixedly connected together, completing the connection between the wire rope component 13 and the steel beam 1. This makes the fixed side plates 8 fixed in multiple positions in the left-right and up-down directions, ensuring the firmness of the installation of the fixed side plates 8 and ensuring that the steel plate 15 is firmly limited inside the steel beam 1.

[0024] Specifically, such as Figure 1 and Figure 5 As shown, a reserved channel 17 is provided on the outer side of the steel beam 1. A reserved channel 2 19 is provided at one end of a sealing pipe 18 provided on one side of the reserved channel 17. The reserved channel 2 19 is provided on the side of the equipment box 16 near the steel beam 1. The two ends of the sealing pipe 18 are fixedly connected to the steel beam 1 and the equipment box 16 respectively. While ensuring the internal sealing of the steel beam 1 through the sealing pipe 18, the inside of the equipment box 16 is connected to the inside of the mounting groove 4, which facilitates the monitoring of the condition of the steel plate 15 inside the steel beam 1.

[0025] Specifically, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, in the displacement control assembly, both T-shaped rods 26 are fixedly installed on the top of the fixed box 20. A pull wire 38 is fixedly connected to the top of the mounting bracket 27 sleeved on the outside of the two T-shaped rods 26. A drive shaft 42 is fixedly connected inside a take-up bracket 41 fixedly connected to one end of the pull wire 38. A brake 43 is sleeved on one end of the drive shaft 42. The outer shell of the brake 43 is fixedly connected to the top of the inner cavity of the equipment box 16. After the brake 43 is activated, the drive shaft 42 is braked; the other end of the drive shaft 42 rotates. A mounting bracket 44 is provided, which is fixedly connected to the top of the inner cavity of the equipment box 16. Under the support of the mounting bracket 44, the drive shaft 42 can rotate, the take-up frame 41 can rotate, the output end of the forward and reverse motor 45 is fixedly connected to the drive shaft 42, and the housing of the forward and reverse motor 45 is fixedly connected to the mounting bracket 44. Therefore, controlling the forward and reverse motor 45 to rotate forward will cause the take-up frame 41 to rotate and wind up the wire 38, and controlling the forward and reverse motor 45 to rotate in reverse will cause the take-up frame 41 to rotate and unwind the wire 38.

[0026] A roller 40 is provided on the outside of the pull wire 38. Both ends of the roller 40 are rotatably connected to the mounting bracket 39. The mounting bracket 39 is fixedly installed on the top of the inner cavity of the equipment box 16. The roller 40 supports and changes the direction of the pull wire 38, increases the direction change space of the pull wire 38, ensures that the take-up frame 41 can smoothly take up or unwind the pull wire 38, avoids the pull wire 38 from getting tangled, and ensures that the pull wire 38 applies a stable pulling force to the mounting bracket 27.

[0027] A mounting bracket 24 is fixedly connected to the bottom of the gas storage component 25. Two T-shaped rods 26 are slidably connected to the mounting bracket 24. A weight-increasing block 21 is provided on the side of the fixed box 20 away from the steel beam 1. Multiple spring-type telescopic rods 47 are fixedly embedded in the weight-increasing block 21. The piston end of the spring-type telescopic rods 47 is fixedly connected to the fixed box 20. Under the action of the two T-shaped rods 26 and the multiple spring-type telescopic rods 47, the relative position between the fixed box 20 and the mounting bracket 24 in the left-right direction can change. Mounting brackets 33 are fixedly connected to both sides of the mounting bracket 27. Two guide rods 34 are passed through each mounting bracket 33. A spring-type telescopic rod 35 is provided at the top of each guide rod 34. The outer wall of the spring-type telescopic rod 35 is flush with the equipment. The top of the inner cavity of the box 16 is fixedly connected, and the piston end of the spring-type telescopic rod 35 is fixedly connected to the adjacent guide rod 34. Under the action of the spring-type telescopic rod 35, the guide rod 34 can move up and down. Under the action of the four guide rods 34, the mounting bracket 27 can only move up and down. The bottom ends of the two guide rods 34 are fixedly connected to the mounting bracket 4 37. The weight block 21 has two inner grooves 36. The mounting bracket 4 37 corresponds to the inner grooves 36 one by one. When the weight block 21 moves up outside the guide rod 34, the position of the guide rod 34 remains unchanged. When the weight block 21 and the fixed box 20 move down, the weight block 21 applies the falling force to the guide rod 34 through the mounting bracket 4 37. The guide rod 34 moves down and the spring-type telescopic rod 35 extends.

[0028] Specifically, such as 5. Figure 7 and Figure 11 As shown, in the transmission assembly, the first air guide 28 is fixedly installed on the bottom side of the air storage component 25. One end of the telescopic pipe 29 fixedly connected to the first air guide 28 is fixedly connected to the second air guide 30, and one end of the second air guide 30 is fixedly connected to the third air guide 31. The air inlet of the pneumatic telescopic rod 32 fixedly connected inside the second mounting frame 27 is fixedly connected to the third air guide 31. Since the telescopic pipe 29 is fixedly connected to the second mounting frame 27, the bottom of the air storage component 25 is fixedly connected to the first mounting frame 24. Both T-shaped rods 26 are slidably connected to the first mounting frame 24. The outer wall of the first air guide 28 is fixedly connected to the first mounting frame 24. Under the action of the telescopic pipe 29 and the first air guide 28, the relative position between the first mounting frame 24 and the second mounting frame 27 remains unchanged. The height limit plate 46 is set on the top of the air storage component 25 and fixedly connected to the inner wall of the equipment box 16. The left and right movement of the fixed box 20 will not affect the relative position of the air storage component 25 and the height limit plate 46 in the vertical direction.

[0029] Furthermore, the piston end of the pneumatic telescopic rod 32 is fixedly connected to the fixed box 20. When the pneumatic telescopic rod 32 extends, it pushes the fixed box 20 to the left. When the pneumatic telescopic rod 32 retracts, the fixed box 20 moves to the right.

[0030] The anchoring structure consists of steel beam 1 and positioning components, while the anchoring monitoring structure consists of equipment box 16, fixing box 20, camera 22, displacement control components, air storage component 25, transmission components, height limit plate 46, etc. The working principle of the anchoring structure and the anchoring monitoring structure is as follows: After completing the connection between the wire rope component 13 and the steel beam 1, and after the steel structure supported by multiple wire rope components 13 and multiple anchoring structures is put into use, when multiple anchoring structures are used to fix multiple wire rope components 13 on the steel structure, only the anchoring monitoring structure is installed on one side of some anchoring structures. When the preset time is reached, the forward and reverse motors 45 in the anchoring monitoring structure, as well as the camera 22 and multiple lights 23 fixedly connected inside the fixing box 20, are controlled to work.

[0031] First, control the forward and reverse motor 45 to reverse, and the take-up frame 41 unwinds the cable 38. At this time, the mounting frame 27 loses its downward limit, and the fixed box 20 and the weight block 21 fall. Under the action of the four guide rods 34, the mounting frame 27 moves up and down. The weight of the fixed box 20 and the weight block 21 is transferred to the guide rods 34 through the mounting frame 4 37. The spring-type telescopic rod 35 extends to meet the horizontal downward movement requirement of the fixed box 20. The two T-shaped rods 26 fixedly connected to the fixed box 20 are fixedly connected to the mounting frame 24. At this time, the mounting frame 24 and the air storage component 25 move down synchronously with the fixed box 20. The two T-shaped rods 26 penetrate the mounting frame 27 and apply the force of the up and down movement to the mounting frame 27. The mounting frame 27 and the pneumatic telescopic rod 32 move up and down synchronously. Therefore, after the forward and reverse motor 45 reverses its operation, the fixed box 20... The camera 22 moves away from the equipment box 16 and faces the steel beam 1. The camera 22 captures images of the bottom of the base 5 and the connection between the steel column 14 and the wire rope component 13, collecting data on the deformation of the bottom of the base 5 and the fracture and corrosion at the connection between the steel column 14 and the wire rope component 13. The bottom of the base 5 and the connection between the steel column 14 and the wire rope component 13 in the anchoring structure along the shooting path of the camera 22 can be captured. When multiple wire rope components 13 and multiple anchoring structures are used to support the steel structure, it is only necessary to install an anchoring monitoring structure on one side of the anchoring structure at a preset position to monitor the safety of the steel structure installed by prestressed anchoring technology. While controlling costs, multiple steel columns 14 and the connection of wire rope components 13 can be monitored to ensure the safety of the steel structure.

[0032] After the forward and reverse motor 45 operates in reverse for a period of time, the forward and reverse motor 45 is controlled to rotate in the forward direction for a period of time. The take-up frame 41 winds up the cable 38, and the mounting frame 27 is pulled upward. The fixed box 20, the weight block 21, the mounting frame 24, and the air storage component 25 move upward, and the spring-type telescopic rod 35 retracts. When the spring-type telescopic rod 35 retracts to its limit, the guide rod 34 remains stationary, and the weight block 21 moves upward along the outside of the guide rod 34. The fixed box 20, the weight block 21, the mounting frame 24, and the air storage component 25 continue to move upward. When the bottom of the fixed box 20 is in contact with the ground, the weight block 21 moves upward. When the bottom wall of the inner cavity of the reserved channel 219 is flush with the top of the air storage component 25, the top of the air storage component 25 abuts against the height limit plate 46 fixedly connected to the inner wall of the equipment box 16. As the fixed box 20 moves upward, the air storage component 25 is pressed down. The air storage component 25 supplies air to the pneumatic telescopic rod 32 through the first air guide component 28, the telescopic pipe 29, the second air guide component 30, and the third air guide component 31. The pneumatic telescopic rod 32 extends and pushes the fixed box 20 into the mounting groove 4. When the top of the fixed box 20 is flush with the top wall of the inner cavity of the reserved channel 219, the forward and reverse motors 45 stop working, and the mounting bracket 227 is no longer subjected to the upward force. When brake 43 operates, it brakes the drive shaft 42, preventing the take-up frame 41 from rotating. The downward force exerted by the fixed box 20 and the weight block 21 acts on brake 43, protecting the forward and reverse motors 45. At this time, camera 22 moves a certain distance to photograph the inside of the mounting slot 4. Multiple lights 23 illuminate the inside of the mounting slot 4, facilitating the camera 22's photographing of the inside of the mounting slot 4. Camera 22 photographs whether the steel plate 15 is deformed, and performs spot checks on some steel plates 15 that are simple in structure, have good sturdiness, but are directly subjected to force, reducing monitoring costs. This investment; the anchoring monitoring structure, composed of equipment box 16, fixed box 20, camera 22, displacement control component, air storage component 25, transmission component, height limit plate 46, etc., comprehensively monitors the bottom of the base 5 exposed to air and affected by external corrosion, as well as the connection points of multiple steel columns 14 and steel wire rope components 13 during application. Multiple steel plates 15 with simple structure, high strength and in a sealed environment are sampled for inspection. The working capacity of the monitoring equipment is reasonably arranged to reduce the cost of monitoring easily damaged locations during the installation of steel structures using prestressed anchoring technology.

[0033] After a monitoring cycle is completed, the forward and reverse motor 45 reverses its operation, the fixed box 20 moves down, the air storage component 25 moves down, the air pressure inside the pneumatic telescopic rod 32 decreases, and the multiple spring-loaded telescopic rods 47 retract, causing the fixed box 20 to move into the equipment box 16. When the fixed box 20 moves into the equipment box 16, the bottom of the air storage component 25 is flush with the bottom of the inner cavity of the reserved channel 19. After the fixed box 20 and the weight block 21 move down and reset, the fixed box 20 and the weight block 21 restore the sealing state inside the equipment box 16, the forward and reverse motor 45 stops working, and the brake 43 works to brake the drive shaft 42.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
