Description

Technical Field

[0001] The invention belongs to the technical field of radial cable and strut connection, in particular to a radial cable and strut connection structure in an annular cable-supported grid structure. Background Art

[0002] As a new type of large-span spatial structure, the annular cable-supported grid structure is widely used in large buildings such as stadiums. The connection structure between the radial cables and the struts is the key part of the structure, which ensures the stability and overall performance of the structure and is of great significance for realizing large-span column-free spaces.

[0003] During the installation of existing annular cable-supported grid structures, the annular cables and radial cables must first be precisely positioned to ensure they are accurately arranged as required. The struts are then installed one by one at the intersections of the radial and annular cables and securely connected to the radial and annular cables via bolts. At the same time, the connection nodes are rigorously quality-checked to ensure they meet design requirements. Upon installation, the entire structure is pre-tensioned to eliminate initial defects and increase its bearing capacity. Professional monitoring equipment is then used to monitor the structure over a long period of time to ensure its safety and stability during use.

[0004] However, during the use of existing radial cables and struts, since the radial cables are made of multiple strands of steel cables twisted together, when the radial cables are exposed to the outdoor environment for a long time, especially the erosion of rainwater, they are very likely to cause rust problems. This rust will produce rust, which will gradually accumulate and accumulate in the gaps of the radial cables. Then, when they are subjected to continuous tension for a long time, unnecessary friction will be generated between the rust and the radial cables. This friction will accelerate the wear process of the radial cables, resulting in the problem of seriously shortening their service life.

[0005] To this end, the present invention provides a connection structure between radial cables and struts in an annular cable-supported grid structure. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

When it moves and abuts the cable clamp, with the assistance of the cable clamp, the two sets of cleaning rings move toward each other and gradually move away until the isosceles trapezoidal fixed frame abuts the cable clamp. Then, after passing the cable clamp, the cleaning ring is reset under the action of the spring, and the spring reset force pulls the connecting rod close to the cable, so that the cleaning ring abuts the cleaning ring again.

At the same time, the lubricating oil can penetrate into the connection between the cable clamp and the cable, lubricating the interior of the cable clamp and the cable.

[0017] The beneficial effects of the present invention are as follows: 1. The radial cable and strut connection structure in the annular cable support grid structure described in the present invention firmly connects the cable through the support rod, the fixed rod, the bottom block and the cable clamp to ensure the stability of the cable. Then, a cleaning assembly is provided at the lower end of the fixed plate.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example 1 like Figures 1 to 7 As shown, a radial cable and strut connection structure in an annular cable support grid structure according to an embodiment of the present invention includes a support rod 1, a plurality of fixed rods 11 are fixedly connected to the lower surface of the support rod 1, a bottom end of each fixed rod 11 is fixedly connected to a bottom block 12, a cable clamp 13 is fixedly connected to the lower surface of each bottom block 12, a plurality of cable clamps 13 are fixedly connected to the same cable 15, a plurality of cable clamps 13 are fixedly connected to the same fixed plate 14 on the lower surface, a cleaning assembly is provided at one end of the fixed plate 14, and the cleaning assembly includes a sliding groove 2 provided on both sides of the fixed plate 14 An electric slide 21 is slidably connected in the sliding groove 2, and two groups of arc-shaped cleaning rings 210 are rotatably provided on the upper surface of the electric slide 21. The two groups of cleaning rings 210 are used to abut the cable 15 and clean the rust on the surface of the cable 15; a lubrication assembly is provided on one side of the electric slide 21, and the lubrication assembly includes a storage box 26 fixedly connected to one side of the electric slide 21, and an auxiliary pipe 226 is fixedly connected to the upper surface of the storage box 26. A plurality of spray holes 227 are opened on one side of the auxiliary pipe 226, and the plurality of spray holes 227 face the cable 15 for spraying lubricating oil.

[0024] Specifically, during use, the existing radial cables and struts are made of multiple twisted steel cables. When the radial cables are exposed to the outdoor environment for a long time, especially the erosion of rainwater, they are very prone to rust. This rust will produce rust, which will gradually accumulate and accumulate in the gaps of the radial cables. When subjected to continuous tension for a long time, unnecessary friction will occur between the rust and the radial cables. This friction will accelerate the wear process of the radial cables, resulting in a serious shortening of their service life. Therefore, the present invention solves this problem by setting up a certain structure. First, the cable 15 is firmly connected by the support rod 1, the fixing rod 11, the bottom block 12 and the cable clamp 13 to ensure the stability of the cable 15. Then, a cleaning component is set on the surface of the fixing plate 14. The electric slide 21 slides in the sliding groove 2, so that the two sets of arc-shaped cleaning rings 210 can move along the surface of the cable 15, effectively cleaning the rust on the cable 15. At the same time, the lubrication component on one side of the electric slide 21 uses the lubricating oil in the storage box 26 to evenly spray the lubricating oil on the surface of the cable 15 through the auxiliary pipe 226 and the spray holes 227 on its side to achieve a lubricating effect. This dual function of cleaning and lubrication improves the maintenance efficiency and service life of the cable 15. The setting of the cleaning component can effectively clean the rust on the surface of the cable 15, prevent the rust from further eroding the cable 15, and ensure its strength and stability. At the same time, through the setting of the lubrication component, the necessary lubrication is provided for the cable 15, reducing friction and extending the service life of the cable 15. In addition, the device also improves the efficiency of maintenance work and reduces manual labor intensity.

[0025] like Figure 3 As shown, a slot 25 is provided at one end of the fixed plate 14 of this embodiment, and a magnetic block 24 is magnetically attracted in the slot 25. A connecting block 22 is fixedly connected to one side of the magnetic block 24, and two plug-in blocks 23 are fixedly connected to one side of the connecting block 22. The two plug-in blocks 23 can be inserted into the sliding groove 2. When the cable 15 is cleaned, the connecting block 22 is pulled out to release the magnetic attraction between the magnetic block 24 and the slot 25. At the same time, the electric slide 21 is inserted into the sliding groove 2, and then the magnetic block is reinserted into the slot 25 to complete the installation of the electric slide 21. After cleaning, the electric slide 21 is removed.

[0026] The two plug-in blocks 23 can be accurately inserted into the sliding groove 2 to block the sliding groove 2 on both sides of the fixed plate 14. When the cable 15 needs to be cleaned, it is only necessary to simply pull out the connecting block 22 to release the magnetic connection between the magnetic block 24 and the slot 25. Then, the electric slide 21 is easily inserted into the sliding groove 2 and the magnetic block is inserted back into the slot 25 again to complete the quick installation of the electric slide 21. After the cleaning work is completed, the electric slide 21 can also be easily removed. This installation method not only simplifies the operation steps and improves work efficiency, but also ensures the stability and accuracy of the electric slide 21 during the installation process. The magnetic connection makes the installation and disassembly process simpler and faster, reduces maintenance costs, and also facilitates daily inspection and maintenance of the equipment, protecting the long-term use of the electric slide 21.

[0027] like Figure 4 and Figure 5 As shown, the cleaning assembly of this embodiment also includes a positioning cavity 216 opened inside the electric slide 21, and a spring 217 is fixed in the positioning cavity 216. One end of the spring 217 is fixed to a connecting rod 218, and one end of the connecting rod 218 is fixed to an isosceles trapezoidal fixed frame 28. A cleaning ring 210 is rotatably connected in the fixed frame 28. After the electric slide 21 is started, it can slide along the sliding groove 2. During the sliding process along the sliding groove 2, the isosceles trapezoidal fixed frame 28 can clean the cable 15. When it moves and abuts against the cable clamp 13, with the assistance of the cable clamp 13, the two sets of cleaning rings 210 move towards each other and gradually move away until the isosceles trapezoidal fixed frame 28 abuts against the cable clamp 13. Then, after passing over the cable clamp 13, the cleaning ring 210 is reset under the action of the spring 217. The restoring force of the spring 217 pulls the connecting rod 218 close to the cable 15, so that the cleaning ring 210 abuts against the cleaning ring 210 again.

[0028] Specifically, after the electric slide 21 is started, it slides along the sliding groove 2, driving the positioning cavity 216 and the fixed frame 28 inside it to move. The isosceles trapezoidal fixed frame 28 can make the cleaning ring 210 closely fit the surface of the cable 15 during the movement, and clean it through the internal cleaning ring 210. When the fixed frame 28 moves to the position of the cable clamp 13, it is assisted by the cable clamp 13. The two fixed frames 28 move toward each other along the cable clamp 13 and gradually move away, thereby driving the two sets of cleaning rings 210 to move toward each other and gradually move away until the fixed frame 28 is completely in contact with the cable clamp 13. At this time, the pressure sensor is triggered, and the cleaning ring 210 rotates into the fixed frame 28. After moving over one of the cable clamps 13, the connecting rod 218 is pulled under the reset force of the spring 217, so that the cleaning ring 210 fits tightly against the surface of the cable 15 again and continues the cleaning work, thereby improving the cleaning efficiency and ensuring the uniformity and comprehensiveness of the cleaning. The isosceles trapezoidal fixed frame 28 enables the cleaning ring 210 to fit tightly against the surface of the cable 15 and effectively remove rust. At the same time, the reset force of the spring 217 ensures that the cleaning ring 210 can quickly reset after passing over the cable clamp 13 and continue to clean the cable 15, thereby simplifying the cleaning process and improving the cleaning quality, providing a strong guarantee for the long-term stable operation of the cable 15.

[0029] like Figure 5 As shown, in this embodiment, a fixed cavity 211 is opened in the fixed frame 28, and a built-in motor 213 is fixed in the fixed cavity 211. The output end of the built-in motor 213 is transmission-connected to a transmission belt 214, and one end of the transmission belt 214 is transmission-connected to a rotating shaft 212. The cleaning ring 210 is fixed to the rotating shaft 212. After the end face of the fixed frame 28 abuts against the cable clamp 13, the end face of the fixed frame 28 is on the same side as the cleaning ring 210. At this time, the pressure sensor on the end face of the fixed frame 28 is subjected to force, and the built-in motor 213 is started. The built-in motor 213 starts to drive the transmission belt 214 for transmission. The transmission belt 214 drives the rotating shaft 212 to rotate, and then drives the cleaning ring 210 to rotate into the fixed cavity 211, so that the fixed frame 28 can pass over the cable clamp 13 under the drive of the electric slide 21. The cleaning ring 210 that rotates into the fixed cavity 211 can not affect the movement of the fixed frame 28.

[0030] like Figure 4 As shown, in this embodiment, a plurality of rotating columns 29 are rotatably provided on both sides of the fixed frame 28. The plurality of rotating columns 29 can assist the cable clamp 13 in squeezing the fixed frame 28 to move away from the cable 15. The provision of the rotating columns 29 reduces direct friction between the fixed block and the cable clamp 13.

[0031] Specifically, the rotating columns 29 provided on both sides of the fixed frame 28 can assist the fixed frame 28 in moving away from the cable 15 when the cable clamp 13 squeezes the fixed frame 28. The rotating characteristics of the rotating columns 29 reduce the direct friction between the fixed frame 28 and the cable clamp 13, making the movement process smoother.

[0032] Example 2 like Figures 1 to 7 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the lubrication assembly includes an auxiliary cavity 219 opened inside the storage box 26, a rack plate 220 is provided inside the auxiliary cavity 219, the rack plate 220 is fixedly connected to the connecting rod 218, the bottom wall of the auxiliary cavity 219 is rotatably connected to a rotating gear 221, the rotating gear 221 is meshed with the rack plate 220, the rotating gear 221 is also meshed with an auxiliary gear 222, a fixing hole 223 is opened on the surface of the auxiliary gear 222, a connecting hole 224 is opened on the top wall of the auxiliary cavity 219, a connecting pipe 225 is fixedly connected to the position of the upper surface of the storage box 26 corresponding to the connecting hole 224, and an auxiliary pipe 226 is fixedly connected to the upper surface of the connecting pipe 225. A pressure pump 27 is fixed to one side of the storage box 26. After the fixed frame 28 is squeezed by the cable clamp 13, the connecting rod 218 drives the rack plate 220 during the sliding process. The rack plate 220 drives the rotating gear 221 to rotate. The rotation of the rotating gear 221 drives the rotation of the auxiliary gear 222. The rotation of the auxiliary gear 222 drives the fixing hole 223 to rotate. When the rack plate 220 rotates to the bottom end, the fixing hole 223 is aligned with the connecting hole 224. At this time, the pressure pump 27 in the storage box 26 will press the lubricating oil into the connecting hole 224 through the fixing hole 223, and then enter the connecting pipe 225, and then enter the auxiliary pipe 226 and be sprayed out from the spray hole 227. The lubrication of the lubricating oil effectively extends the service life of the cable 15.

[0033] like Figure 1 and Figure 4 As shown, the lubricating oil sprayed from the spray hole 227 of this embodiment falls on the surface of the cable 15 and penetrates into the interior of the cable 15, reducing the friction inside the cable 15. At the same time, the lubricating oil can penetrate into the connection between the cable clamp 13 and the cable 15, lubricating the interior of the cable clamp 13 and the cable 15.

[0034] Specifically, the lubricating oil sprayed from the spray hole 227 evenly covers the surface of the cable 15 and gradually penetrates into the interior thereof, effectively reducing the friction inside the cable 15. At the same time, the lubricating oil can also penetrate into the connection between the cable clamp 13 and the cable 15, fully lubricating the interior of these two components, thereby improving the operating efficiency of the cable 15 and the cable clamp 13, extending their service life, and reducing the loss and failure rate caused by friction.

[0035] Working principle: First, the cable 15 is firmly connected through the support rod 1, the fixed rod 11, the bottom block 12 and the cable clamp 13 to ensure the stability of the cable 15. Then, the magnetic block 24 is magnetically attracted in the slot 25 opened at one end of the fixed plate 14 to achieve convenient installation and disassembly of the electric slide 21. The connecting block 22 fixed on one side of the magnetic block 24 has two plug-in blocks 23. These two plug-in blocks 23 can be accurately inserted into the sliding groove 2 to block the sliding grooves 2 on both sides of the fixed plate 14. When the cable 15 needs to be cleaned, it is only necessary to simply pull out the connecting block 22 to release the magnetic block 24 from the slot 2. 5, then easily insert the electric slide 21 into the sliding slot 2, and insert the magnetic block back into the slot 25 again to complete the quick installation of the electric slide 21. After the cleaning work is completed, the electric slide 21 can also be easily removed. This installation method not only simplifies the operation steps and improves work efficiency, but also ensures the stability and accuracy of the electric slide 21 during the installation process. The magnetic connection makes the installation and removal process simpler and faster, reduces maintenance costs, and also facilitates daily inspection and maintenance of the equipment, protecting the long-term use of the electric slide 21. In addition, a cleaning assembly is provided on the lower surface of the fixed plate 14. The electric slide 21 slides in the sliding groove 2. After the electric slide 21 is started, it slides along the sliding groove 2, driving the positioning cavity 216 and the fixed frame 28 inside it to move. The isosceles trapezoidal fixed frame 28 can make the cleaning ring 210 closely fit the surface of the cable 15 during the movement, and clean it through the internal cleaning ring 210. When the fixed frame 28 moves to the position of the cable clamp 13, it is assisted by the cable clamp 13. The two fixed frames 28 move towards each other along the cable clamp 13 and gradually move away, thereby driving the two sets of cleaning rings 210 to move. The fixing frame 28 moves toward each other and gradually moves away from each other until the end face of the fixing frame 28 contacts the cable clamp 13, and the end face of the fixing frame 28 is on the same side as the cleaning ring 210. At this time, the pressure sensor on the end face of the fixing frame 28 is stressed, and the built-in motor 213 is started. The built-in motor 213 starts to drive the transmission belt 214 to transmit the power, and the transmission belt 214 drives the rotating shaft 212 to rotate, thereby driving the cleaning ring 210 to rotate into the fixing cavity 211. The fixing frame 28 can pass over the cable clamp 13 under the drive of the electric slide 21. The cleaning ring 210 that rotates into the fixing cavity 211 can not affect the movement of the fixing frame 28. After moving over one of the cable clamps 13, the connecting rod 218 is pulled under the reset force of the spring 217, so that the cleaning ring 210 is again closely fitted to the surface of the cable 15 to continue cleaning, thereby improving the cleaning efficiency and ensuring the uniformity and comprehensiveness of the cleaning. The isosceles trapezoidal fixed frame 28 enables the cleaning ring 210 to be closely fitted to the surface of the cable 15, effectively removing rust. At the same time, the reset force of the spring 217 ensures that the cleaning ring 210 can be quickly reset after passing over the cable clamp 13, and continue to clean the cable 15, thereby simplifying the cleaning process and improving the cleaning quality, providing a strong guarantee for the long-term stable operation of the cable 15. At the same time, the lubrication assembly on one side of the electric slide 21 uses the lubricating oil in the storage box 26 to evenly spray the lubricating oil onto the surface of the cable 15 through the auxiliary pipe 226 and the spray holes 227 on its side, thereby achieving a lubricating effect. This dual function of cleaning and lubricating improves the maintenance efficiency and service life of the cable 15. The setting of the cleaning component can effectively clean the rust on the surface of the cable 15, prevent the rust from further eroding the cable 15, and ensure its strength and stability. At the same time, through the setting of the lubricating component, when the fixing frame 28 is squeezed by the cable clamp 13, the connecting rod 218 drives the rack plate 220 during the sliding process, and the rack plate 220 drives the rotating gear 221 to rotate. The rotation of the rotating gear 221 drives the rotation of the auxiliary gear 222, and the rotation of the auxiliary gear 222 drives the fixing hole 223 to rotate. When the rack plate 220 rotates to the bottom end, the fixing hole 223 and the connecting hole 224 are aligned. At this time, the pressure pump 27 in the storage box 26 will press the lubricating oil into the connecting hole 224 through the fixing hole 223, and then enter the connecting pipe 225, and then enter the auxiliary pipe 226 and be sprayed out from the spray hole 227. The lubrication of the lubricating oil effectively extends the service life of the cable 15. In addition, the device also improves the efficiency of maintenance work and reduces labor intensity.
