Abstract
Description
Technical Field
[0001] This application relates to the field of power operation equipment technology, and in particular to a cable-stayed tower dismantling device. Background Technology
[0002] Currently, the main methods for dismantling cable-stayed towers used for power transmission in the power industry are cutting and dismantling, and crane hoisting and dismantling.
[0003] The cutting and dismantling method involves selecting the direction of the cable-stayed tower's collapse based on the site conditions, removing the steel wire ropes and ground anchors on that side, cutting the outriggers near the steel wire ropes on the other side and tightening them, causing the cable-stayed tower to fall, and then dismantling the tower materials from top to bottom. This method has a high risk factor, requires a large site area, incurs high compensation costs, and is difficult to implement.
[0004] The crane-lifting dismantling method involves dismantling the tower in sections from top to bottom. First, the top section of the cable-stayed tower is dismantled and lifted away, then another section is dismantled and lifted away, and so on until the entire tower is dismantled. This method requires high-altitude operations, carries a high risk factor, high construction costs, and is difficult to implement. For tall and heavy cable-stayed towers, large-tonnage cranes are required, leading to longer crane assembly times, stricter environmental requirements, and the risk of foundation settlement during heavy lifting causing the top of the tower to shift, significantly increasing the difficulty of implementation.
[0005] Therefore, the current methods for dismantling cable-stayed towers are characterized by high difficulty, high risk, and high cost. Summary of the Invention

[0036] See Figures 1 to 3 The diagram shows a structural schematic of a cable-stayed tower dismantling device according to an embodiment of this application. The device includes a frame mechanism 100, a clamping mechanism 200, and a lifting mechanism 300. The frame mechanism 100 includes a frame body 110 and a pulley assembly 120, with the pulley assembly 120 disposed on the top of the frame body 110. The frame body 110 is installed around the bottom of the cable-stayed tower to be dismantled.
[0037] The clamping mechanism 200 is movably installed within the frame 110. The clamping mechanism 200 includes a movable frame 210, at least two drive components 220, and at least two clamping components 230. The movable frame 210 has at least two extensions 211. The drive components 220 are correspondingly installed on the extensions 211. The power output ends of the drive components 220 are connected to the clamping components 230. The drive components 220 are used to drive the clamping components 230 to move towards or away from each other so that the position of the clamping components 230 corresponds to the cable-stayed tower to be dismantled, facilitating the connection between the clamping components 230 and the cable-stayed tower to be dismantled. The drive components 220 are also used to lift the cable-stayed tower to be dismantled.
[0038] The lifting mechanism 300 includes a connecting rope 310, a winch 320, and a mounting base 330. The mounting base 330 is located on one side of the frame mechanism 100 and is fixed to the ground. The winch 320 is mounted on the mounting base 330. One end of the connecting rope 310 is connected to the winch 320, and the other end is connected to the movable frame 210 via a pulley assembly 120. The pulley assembly 120 guides the connecting rope 310, ensuring that the connecting rope 310 is vertically connected to the center of the movable frame 210, thus preventing deviation during the lifting or lowering of the clamping mechanism 200 driven by the winch 320. Specifically, the connecting rope 310 is a steel wire rope.
[0039] The cable-stayed tower dismantling device described in this application embodiment includes a movable clamping mechanism 200 installed within a frame mechanism 100. A frame body 110 is installed around the bottom of the cable-stayed tower to be dismantled. A mounting base 330 is fixed on one side of the frame body 110, and a winch 320 is installed on the mounting base 330. The winch 320 is connected to the clamping mechanism 200 via a connecting rope 310 that passes around a pulley assembly 120, thereby driving the clamping mechanism 200 to move up and down within the frame body 110. Specifically, the movable frame 210 of the clamping mechanism 200 is connected to the connecting rope 310. The movable frame 210 is provided with at least two extensions 211. Each extension 211 is provided with a drive assembly 220 and a clamp assembly 230. The drive assembly 220 is used to drive the clamp assembly 230 to adjust its position so that the clamp assembly 230 can easily connect to the cable tower to be dismantled. After the clamp assembly 230 connects to the cable tower, it drives the clamp assembly 230 to lift the cable tower. Then, the bottom of the cable tower is dismantled by the reverse dismantling method. After dismantling, the cable tower is lowered by the winch 320. The operation is repeated until the entire cable tower is dismantled.
[0040] The cable-stayed tower dismantling device described in this application embodiment involves setting a frame 110 (frame mechanism 100) at the bottom of the cable-stayed tower to be dismantled. A clamping mechanism 200 installed within the frame 110 connects to and lifts the cable-stayed tower, thereby dismantling its bottom. After dismantling, a lifting mechanism 300 lowers the tower and changes the connection position of the clamping mechanism 200. This process is repeated until the entire cable-stayed tower is dismantled. The device eliminates the need for high-altitude operations, reducing the risks associated with such work and achieving a simple, safe, and efficient tower dismantling process. It significantly simplifies the construction process, improves work efficiency, and offers advantages such as ease of operation, high safety, and low cost.
[0041] Combination Figure 4 This diagram illustrates the structure of the clamping mechanism 200 of a cable-stayed tower dismantling device according to one embodiment of this application. In some embodiments, the drive assembly 220 includes a drive unit 221, a slider 224, and a threaded block 225. A threaded rod 223 is rotatably disposed at the bottom of an extension 211, and a slider 222 is disposed parallel to one side of the threaded rod 223, with the extension directions of both the threaded rod 223 and the slider 222 aligned with the extension direction of the cable-stayed tower. The drive unit 221 is mounted at the end of the extension 211, and its power output end is connected to the threaded rod 223. The slider 224 is movably disposed on the slider 222, and the threaded block 225 is movably disposed on the threaded rod 223. A clamp assembly 230 is connected to the slider 224 and the threaded block 225. The drive unit 221 drives the threaded rod 223 to rotate, thereby causing the threaded block 225 to move on the threaded rod 223. Furthermore, the clamp assembly 230 and the slider 224 move integrally with the threaded block 225. The slider 224 and the threaded block 225 are connected as one unit.
[0042] In this embodiment, the drive assembly 220 is used to drive the clamp assembly 230 to move, so that the clamp assembly 230 moves to the position corresponding to the cable tower to be dismantled and connects to the cable tower and raises it. Specifically, the drive unit 221 drives the threaded rod 223 to rotate, thereby causing the threaded block 225 to move on the threaded rod 223. The clamp assembly 230, the threaded block 225, and the slider 224 are connected as a whole, thereby driving the clamp assembly 230 and the slider 224 to move together, achieving the purpose of driving the clamp assembly 230. Among them, the slider 224 and the sliding rod 222 can share the pressure of the threaded rod 223, improving the stability of the drive assembly 220.
[0043] In one exemplary embodiment, such as Figure 4 As shown, the bottom of the extension 211 is provided with a mounting groove 211A, the slide bar 222 and the threaded bar 223 are installed in the mounting groove 211A, and the drive unit 221 is provided at the end of the extension 211.
[0044] In one exemplary embodiment, the drive unit 221 is a motor that can achieve precise speed and torque control, thereby accurately controlling the action when dismantling the cable tower.
[0045] In an optional embodiment, such as Figure 4 As shown, the clamp assembly 230 includes a connecting frame 231, a first rope frame 232, a second rope frame 233, a clamp frame 234, and multiple lifting ropes 235. One end of the connecting frame 231 is connected to the bottom of the slider 224 and the threaded block 225, and the other end of the connecting frame 231 is connected to the first rope frame 232. The first rope frame 232 is provided with multiple first rollers 2321, and the second rope frame 233 is provided with multiple second rollers 2331. The lifting ropes 235 are fitted one-to-one with the first rollers 2321 and the second rollers 2331, and the clamp frame 234 is connected to the second rope frame 233. One end of the clamp assembly 230 is connected to the slider 224 and the threaded block 225 via the connecting frame 231. The other end of the clamp assembly 230 is provided with a clamp frame 234 for connecting the cable-stayed tower to be dismantled. A first rope frame 232 is provided between the connecting frame 231 and the clamp frame 234 and connected to the connecting frame 231, and a second rope frame 233 is provided between the clamp frame 234 and the first rope frame 232 has multiple first rollers 2321 and multiple second rollers 2331 of the second rope frame 233 connected one-to-one by a suspension rope 235, thereby increasing the range of motion of the clamp frame 234. When the clamp frame 234 is installed on the cable-stayed tower to be dismantled, the clamp frame 234 can be easily moved to align with the cable-stayed tower, which has the advantages of simplifying the construction process and being easy to use.
[0046] In an optional embodiment, such as Figure 4 As shown, the clamp frame 234 is provided with a locking groove 234A. By locking the cable-stayed tower into the locking groove 234A, the cable-stayed tower can be pulled and lifted. The clamp frame 234 also includes a reinforcing rib 2341, which is set at the bend of the locking groove 234A. In order to improve the structural strength of the clamp frame 234, the reinforcing rib 2341 is set at the bend of the clamp frame 234, ensuring the durability and stability of the clamp frame 234 during use.
[0047] Furthermore, the clamp bracket 234 is also provided with connection holes, which can be used to securely connect the clamp bracket 234 and the cable tower with fasteners, thereby ensuring the stability of the connection.
[0048] In an optional embodiment, such as Figure 4 and Figure 5As shown, the trolley assembly 120 includes a first trolley 121, a second trolley 122, and a third trolley 123. The first trolley 121 is located at the top center of the frame 110, the second trolley 122 is located on the top of the frame 110 near the lifting mechanism 300, and the third trolley 123 is located on the top of the frame 110, between the first trolley 121 and the second trolley 122. The connecting rope 310 connects the movable frame 210 through the second trolley 122, the third trolley 123, and the first trolley 121 in sequence. By sequentially arranging a first trolley 121, a third trolley 123, and a second trolley 122 from the top center to the side of the frame 110, the connecting rope 310 can change its extension direction through the first trolley 121, the third trolley 123, and the second trolley 122. This adjusts the connecting rope 310 to be connected vertically to the center position of the movable frame 210, preventing the clamping mechanism 200 from shifting due to the deviation of the lifting direction of the connecting rope 310, thereby improving safety during use.
[0049] In an optional embodiment, such as Figure 5 As shown, the frame mechanism 100 also includes a limiting component 130, which includes a guide plate 131, a limiting ring 132, and limiting rollers 133. One end of the guide plate 131 is connected to the top of the frame 110, and the other end of the guide plate 131 is connected to the limiting ring 132. The central axis of the limiting ring 132 is tangent to the first trolley 121. The limiting rollers 133 are disposed within the hollow of the limiting ring 132. The connecting rope 310 passes around the first trolley 121 and through the limiting rollers 133. Specifically, four limiting rollers 133 are included. By setting the limiting ring 132 at the output end directly below the first trolley 121, and setting the limiting rollers 133 in the hollow part of the limiting ring 132, the connecting rope 310 outputting from the first trolley 121 passes through the limiting rollers 133 and connects to the movable frame 210, thereby providing auxiliary limiting for the rising or falling position of the connecting rope 310 and maintaining the stable lifting and lowering of the connecting rope 310.
[0050] In an optional embodiment, such as Figure 1 and Figure 4 As shown, there are four extensions 211, which are perpendicular to each other. There are also four drive assemblies 220 and four clamp assemblies 230. Each extension 211 is equipped with a drive assembly 220, and each drive assembly 220 is connected to a clamp assembly 230. Since cable-stayed towers typically have four sides, by providing four extensions 211 connected in a cross structure, with each extension 211 equipped with a drive assembly 220 and a clamp assembly 230, and each clamp assembly 230 connected to one side of the cable-stayed tower, the tower can be stably raised and lowered. This method offers advantages such as ease of operation and high safety.
[0051] Furthermore, such as Figure 4 As shown, each extension 211 is provided with a lifting lug 213. The connecting rope 310 is connected to multiple sub-connecting ropes 311 at the end of the connecting movable frame 210. The sub-connecting ropes 311 are used to connect to the lifting lug 213 one by one, so that the tension of the connecting rope 310 on the movable frame 210 is distributed to each extension 211, making the clamping mechanism 200 more stable during the lifting process, reducing the possibility of tilting, and improving the safety of use.
[0052] In an optional embodiment, such as Figure 4 As shown, the cable-stayed tower dismantling device also includes a tilt sensing module 212, which is mounted on the movable frame 210. By mounting the tilt sensing module 212 on the movable frame 210, the tilt sensing module 212 monitors the tilt of the cable-stayed tower during hoisting. When a slight tilt occurs, it can be adjusted or stopped in time to avoid collapse and improve the safety of dismantling.
[0053] Furthermore, such as Figure 4 and Figure 5 As shown, the cable-stayed tower dismantling device also includes multiple tension sensing modules 124. The first trolley 121, the second trolley 122, and the third trolley 123 are all connected to the frame 110 through the tension sensing modules 124. By installing tension sensing modules 124 at the connection ends of the first trolley 121, the second trolley 122, and the third trolley 123, the tension of the connecting rope 310 can be detected, preventing the tension from exceeding the safe bearing limit of the frame 110 and ensuring the safe and stable operation of the equipment.
[0054] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the frame 110 includes a rectangular frame 111, a top frame 112, multiple protective frames 113, and multiple fixing plates 114. A clamping mechanism 200 is disposed within the rectangular frame 111. The top frame 112 is installed on the top of the rectangular frame 111. A trolley assembly 120 and a limiting assembly 130 are both connected to the bottom of the top frame 112. Protective frames 113 are installed on each side of the rectangular frame 111. Multiple fixing plates 114 are spaced apart at the bottom of the rectangular frame 111, and each fixing plate 114 has mounting holes. The rectangular frame 111 is connected to ground anchors and fixing plates 114 via tie rods, thereby fixing the frame 110. By providing a top frame 112 on the top of the rectangular frame 111 for installing the trolley assembly 120 and the limiting assembly 130, and by providing protective frames 113 on each side of the rectangular frame 111, the structural strength of the entire frame 110 is improved, enhancing its stability and safety during use.
[0055] In an optional embodiment, such as Figure 3As shown, the mounting base 330 is connected to the ground anchor via a tie rod. The ground anchor is dug to a depth of 2-3 meters depending on the soil conditions, and has a load capacity of 20 tons. This ensures that the anchor will not be pulled or displaced when the winch 320 is under load, thus ensuring the smooth descent of the cable-stayed tower.
[0056] The cable-stayed tower dismantling device described in this application has the following beneficial effects:
[0057] 1. By setting up a frame 110 with a frame mechanism 100 at the bottom of the cable-stayed tower to be dismantled, and a clamping mechanism 200 installed within the frame 110 to connect to and lift the cable-stayed tower, the bottom of the tower is dismantled. After dismantling, a lifting mechanism 300 lowers the tower and changes the connection position of the clamping mechanism 200. This process is repeated until the entire cable-stayed tower is dismantled. This method eliminates the need for high-altitude operations, reducing the risks associated with such work and achieving a simple, safe, and efficient tower dismantling process. It significantly simplifies the construction process, improves work efficiency, and offers advantages such as ease of operation, high safety, and low cost.
[0058] 2. By installing an angle sensing module 212 on the movable frame 210, the angle sensing module 212 is used to monitor the tilt of the cable-stayed tower during hoisting. When a slight tilt occurs, it can be adjusted or stopped in time to avoid collapse and improve the safety during dismantling.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
