Description

Technical Field

[0001] The invention relates to the technical field of hoisting, and in particular to a hoisting tool for a tower. Background Art

[0002] In a wind farm, any non-streamlined object will alternately generate vortices that detach from the surface of the structure on both sides of the object at a constant flow rate. These vortices will generate pulsating pressures on the column that periodically change along and across the flow. If the tower is elastically supported or the flexible pipe body is allowed to deform elastically, the pulsating fluid force will induce periodic vibration of the tower. This regular column vibration will in turn change the vortex emission pattern of its wake. This phenomenon is called vortex-induced vibration. When the natural frequency of the tower is close to the emission frequency of the vortex, the tower will be damaged by resonance. Therefore, by installing spoilers on the tower, the trajectory of the incoming wind can be effectively disrupted, destroying the conditions for the formation of vortices, thereby suppressing vortex-induced vibration and protecting the tower from resonance damage.

[0003] A patent application document with publication number CN116255043A discloses a method for installing a high-tower spoiler device, including a tower, wherein the outer wall of the upper end of the tower is provided with a first through hole, and the outer wall of the lower end of the tower is provided with a second through hole. The installation method is specifically: fixing one end of the spoiler assembly in the first through hole; lifting and turning over the tower; pulling the other end of the spoiler assembly and winding it along the outer wall of the tower; fixing the other end of the spoiler assembly in the second through hole; the installation method is not only safe and reliable, but also reduces the installation and disassembly costs of the spoiler assembly.

[0004] In the above technical solution, when installing the spoiler assembly, the tower is first hoisted into a vertical state, and then the lower end of the spoiler assembly is pulled to rotate around the tower to wrap the spoiler assembly around the outer wall of the tower. Since this process is in the tower hoisting stage, there is a certain degree of danger. Moreover, due to the large size of the tower, it usually requires multiple workers to work synchronously, which results in low efficiency. Summary of the invention

[0005] The invention provides a tower hoisting tool, aiming to solve the problem of low efficiency and certain danger in installing spoiler components in the related art.

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figures 1 to 6 As shown, the tower hoisting tool according to the embodiment of the present invention comprises a mounting belt 2, a rotating assembly and a driving assembly.

[0025] The mounting belt 2 is used to be installed at the lower end of the tower 1, and the mounting belt 2 is used to be connected to one end of the spoiler strip 11. Specifically, in the initial state, the tower 1 lies horizontally on the ground. Before hoisting, the mounting belt 2 is first fixedly sleeved on the bottom of the tower 1, and one end of the spoiler strip 11 is fixedly connected to the mounting belt 2. A lifting ring 9 is installed at the top of the tower 1 to facilitate the use of a lifting device to lift and hoist the tower 1.

[0026] The rotating assembly includes an annular frame and a gear ring. The annular frame is spliced ​​by multiple arc-shaped members 31. The arc-shaped member 31 is detachably mounted on the upper end of the tower 1 through a connecting assembly 5. The connecting assembly 5 includes a fixing member 51, a positioning member 52 and a connecting rod 53. The fixing member 51 is detachably connected to the tower 1 through a bolt structure. The positioning member 52 is fixedly connected to the arc-shaped member 31. The connecting rod 53 is fixedly connected to the fixing member 51. The connecting rod 53 is slidably connected to the positioning member 52. The length direction of the connecting rod 53 extends along the radial direction of the annular frame. The connecting rod 53 is evenly spaced on the length direction thereof. The connecting rod 53 is fixedly connected to the positioning member 52 through bolts. Since the diameter of the spliced ​​annular frame is fixed, the diameter size of the upper end of the tower 1 will also be different according to different actual conditions. After the spliced ​​annular frame is arranged on the outer peripheral side of the upper end of the tower 1, the positioning member 52 can be fixed to the threaded hole at the corresponding position on the connecting rod 53 according to the diameter size of the upper end of the tower 1, which is convenient for use.

[0027] The gear ring is composed of multiple arc-shaped gear rods 32, and an arc-shaped groove is provided in the arc-shaped part 31 along its extension direction. The multiple arc-shaped gear rods 32 are slidably fitted in the arc-shaped grooves of the multiple arc-shaped parts 31 one by one. The gear ring and the annular frame are concentrically arranged, and the gear ring can rotate around the center of the annular frame, and the teeth on the arc-shaped gear rods 32 face the inner side of the gear ring.

[0028] The driving assembly includes a winding wheel 41 and a gear three 42. The winding wheel 41 is rotatably mounted on the arc-shaped member 31, and a traction rope (not shown in the figure) is wound around the winding wheel 41. The winding wheel 41 is connected to the gear three 42 through a transmission structure one. When the winding wheel 41 is controlled to rotate, the gear three 42 can be driven to rotate. The gear three 42 is meshed with the gear ring. Specifically, the winding wheel 41 is rotatably connected to the positioning member 52. The transmission structure one includes a bevel gear one 431 and a bevel gear two 432 that mesh with each other. The bevel gears One 431 is coaxially fixedly connected to the winding wheel 41, bevel gear two 432 is rotationally connected to the positioning member 52, and is coaxially fixedly connected to gear three 42, the inner side of the arc member 31 is provided with an opening one 311 connected to the arc groove, and gear three 42 meshes with the gear ring at the opening one 311, so that when the traction rope is pulled to drive the winding wheel 41 to rotate, the bevel gear one 431 can be driven to rotate, and through the meshing of bevel gear one 431 and bevel gear two 432, the gear three 42 and the gear ring can be driven to rotate.

[0029] The bottom of the arc-shaped member 31 is provided with an opening 2 312 connected to the arc-shaped groove, so that the bottom of the annular frame formed by splicing multiple arc-shaped members 31 can form a circular opening formed by splicing multiple openings 2 312, and the lower side of the arc-shaped member 31 is provided with a hanging ring 6, which is fixedly connected to the arc-shaped gear rod 32 at the opening 1 311, and the hanging ring 6 is used to be connected to the upper end of the spoiler strip 11.

[0030] In the initial state, the tower 1 lies horizontally on the ground. Before hoisting, the installation belt 2 is first fixedly sleeved on the bottom of the tower 1, one end of the spoiler strip 11 is fixedly connected to the installation belt 2, and the other end is fixedly connected to the hanging ring 6. Then, the tower 1 is changed to a vertical state and lifted by a set distance through the hoisting device. Next, the traction rope is pulled downward to drive the winding wheel 41 to rotate, which can drive the bevel gear 1 431 to rotate. Through the meshing of the bevel gear 1 431 and the bevel gear 2 432, the gear 3 can be driven. 42 and the gear ring rotate, and the hanging ring 6 fixedly connected to the lower part of the gear ring will rotate synchronously with the gear ring, thereby driving the upper end of the spoiler strip 11 to rotate, and enabling the spoiler strip 11 to be spirally wound on the tower 1. After the spiral winding of the spoiler strip 11 is completed, the staff located at the upper end of the tower 1 can remove the upper end of the spoiler strip 11 from the hanging ring 6 and connect it to the upper end of the tower 1, and at the same time, the fixing member 51, the positioning member 52, the annular frame, the gear ring and other structures can be removed from the tower 1.

[0031] In some embodiments, Figures 4 to 6 As shown, the outer sides of both ends of the arc-shaped gear rod 32 are provided with a slot 321, and a baffle 7 is movably fitted at the slot 321. The baffle 7 is slidably connected to the arc-shaped member 31, and the baffle 7 can slide along the radial direction of the annular frame. When the annular frame and the gear ring are spliced, two adjacent arc-shaped members 31 can stop against each other, and two adjacent arc-shaped gear rods 32 can stop against each other.

[0032] A control component for controlling the movement of the baffle 7 is provided at the end of the arc-shaped member 31, and the control component includes an extension portion 81, a movable block 82, an elastic member 83 and a transmission structure 2. The extension portion 81 is fixedly connected to the arc-shaped member 31, and the baffle 7 is located on the upper side of the extension portion 81. A receiving groove is provided in the extension portion 81, and the movable block 82 is slidably fitted in the receiving groove, and the sliding direction of the movable block 82 is perpendicular to the sliding direction of the baffle 7. The elastic member 83 is arranged between the movable block 82 and the extension portion 81. The elastic member 83 can be a spring, and its two ends are respectively fixedly connected to the movable block 82 and the baffle 7. The elastic member 83 can make part of the movable block 82 extend to the outside of the extension portion 81.

[0033] Transmission structure 2 includes rack 1 841, rack 2 842, gear 4 843 and gear 5 844. Rack 1 841 is fixedly connected to the baffle 7. The arrangement direction of the teeth on rack 1 841 is the same as the sliding direction of the baffle 7. Rack 2 842 is fixedly connected to the movable block 82. The arrangement direction of the teeth on rack 2 842 is the same as the sliding direction of the movable block 82. Gear 4 843 meshes with rack 1 841. Gear 5 844 is coaxially fixedly connected to the bottom of gear 4 843 and is rotationally connected to the extension 81. Gear 5 844 meshes with rack 2 842.

[0034] Before the multiple arc-shaped pieces 31 are spliced ​​into the annular frame, the baffle 7 is clamped in the slot 321 to block and limit the arc-shaped gear rod 32 to prevent the arc-shaped gear rod 32 from sliding out of the arc-shaped piece 31. At this time, part of the movable block 82 is pushed out to the outside of the end of the arc-shaped piece 31 by the elastic member 83. When the annular frame is spliced, the two adjacent arc-shaped pieces 31 are controlled to stop each other, and the two movable blocks 82 corresponding to the two arc-shaped pieces 31 will press against each other, and the movable block 82 will move toward the inner direction of the accommodating groove, and the engagement of the rack 2 842 and the gear 5 844 will drive the gear 5 844 and the gear 4 843 to rotate, and the engagement of the gear 4 843 and the rack 1 841 will drive the baffle 7 to move toward the outer side of the annular frame until it is disengaged from the slot 321. At this time, the baffle 7 no longer blocks the arc-shaped gear rod 32, so that the gear ring formed by splicing multiple arc-shaped gear rods 32 can rotate along the circumferential direction of the annular frame.

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
