[0025] The tower hoisting and docking auxiliary tooling of the present invention will be described in more detail below with reference to schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being generally known to those skilled in the art and not as limiting the present invention.

[0026] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are provided solely for the purpose of assisting in the description of the embodiments of the present invention.

[0027] like Figures 1 to 5 As shown, the embodiment of the present invention proposes a tower hoisting and docking auxiliary tooling, including two positioning ring tubes 1, two positioning hooks 2 and a synchronous shrinkage device 3;

[0028] The positioning ring 1 is located outside the tower, and is used to connect the two towers at the horizontal assembly position;

[0029] The outer end of the positioning hook 2 is detachably connected to the positioning ring tube 1, and the inner end of the positioning hook 2 is fixedly connected to the synchronous shrinkage device 3;

[0030] The synchronous shrinkage device 3 is located inside the tower, and the synchronous shrinkage device 3 drives the positioning ring tube 1 and the tower to be positioned and closed by synchronously shrinking the positioning hook 2.

[0031] In this embodiment, during the installation process of the hoisting tower, the positioning ring tube 1 is located between the two towers, and then the two positioning ring tubes 1 are connected using the positioning hook 2. Finally, the two positioning ring tubes 1 are synchronously closed through the synchronous shrinkage device 3. The positioning ring tube 1 gradually corrects the hoisted tower to be flush with the tower installed below, completing the rapid positioning of the hoisted tower. At this time, the two towers can be connected using bolts, and the positioning hook 2 can be removed to complete the entire hoisting and docking task.

[0032] Furthermore, the positioning ring is matched with the outer side wall of the tower, two lifting ropes are provided on the top surface of the positioning ring 1, and the positioning ring 1 is lifted synchronously with the tower.

[0033] Specifically, when hoisting the tower to be installed, two positioning ring tubes 1 are hoisted at the same time, and the positioning ring tubes 1 are located below the tower. When the two towers are close to each other, the two positioning ring tubes 1 are connected using the positioning hook 2, and the positions of the two towers are aligned using the synchronous shrinkage device 3, thereby completing the tower hoisting and docking task.

[0034] Furthermore, a disassembly groove 4 matching the positioning hook 2 is provided through the positioning ring tube 1 , and the positioning hook 2 passes through the disassembly groove 4 and is rotated and dislocated to be engaged with the positioning ring tube 1 .

[0035] Specifically, when docking the positioning tower with the positioning hook 2, first insert the positioning hook 2 through the disassembly slot 4 and rotate the positioning hook 2. At this time, the positioning hook 2 and the disassembly slot 4 are misaligned, thus achieving a quick connection between the positioning ring 1 and the positioning hook 2. When the positioning hook 2 needs to be disassembled, the positioning hook 2 is rotated. When the positioning hook 2 is aligned with the disassembly slot 4, the positioning hook 2 can be removed from the disassembly slot 4.

[0036] In order to facilitate the removal of the positioning hook 2, the edge of the disassembly and assembly groove 4 is chamfered. After the edge of the disassembly and assembly groove 4 is chamfered, an inclined surface is formed, which guides the positioning hook 2 to be quickly removed and inserted.

[0037] Furthermore, the positioning hook 2 includes a positioning rod 5, the end of which is provided with a connecting rod 6 matching the disassembly and assembly groove 4, a limiting rod 7 is provided inside the connecting rod 6, and the tower is located between the connecting rod 6 and the limiting rod 7 when positioned.

[0038] Specifically, when installing the positioning hook 2, align the connecting rod 6 with the disassembly slot 4 and insert it to achieve a quick connection between the connecting rod 6 and the disassembly slot 4. After the connecting rod 6 is inserted into the disassembly slot 4, the limiting rod 7 fits against the inner wall of the tower. At this time, the tower is snapped onto the positioning hook 2, and the synchronous shrink device 3 can be used to quickly achieve the tower docking operation.

[0039] In a specific embodiment, the length of the connecting rod 6 is not greater than the length of the disassembly slot 4 , and the length of the limiting rod 7 is greater than the length of the disassembly slot 4 .

[0040] Specifically, the length of the connecting rod 6 is not greater than the length of the disassembly slot 4, which makes it convenient to insert the connecting rod 6 into the disassembly slot 4. After the connecting rod 6 is inserted into the disassembly slot 4, since the length of the limiting rod 7 is greater than the length of the disassembly slot 4, the limiting rod 7 will not pass through the disassembly slot 4. At this time, the tower is stuck on the positioning hook 2, and the tower lifting and docking operation is realized under the contraction of the synchronous shrinker 3.

[0041] In order to facilitate the insertion of the positioning hook 2 into the disassembly slot 4 or the removal of the positioning hook 2 from the disassembly slot 4, the connecting rod 6 and the limiting rod 7 are in the same plane. The connecting rod 6 and the limiting rod 7 are in the same plane and rotate synchronously, which facilitates the alignment of the connecting rod 6 and the limiting rod 7 with the disassembly slot 4, thereby facilitating the installation and removal of the positioning hook 2.

[0042] Furthermore, the synchronous shrinkage device 3 includes a transmission box 8, in which a synchronous gear 9 is installed for rotation via a rotating shaft. Two racks 10 are meshedly connected to the synchronous gear 9, and the two racks 10 are fixedly connected to the two positioning hooks 2 respectively.

[0043] Specifically, after the positioning hook 2 is inserted and connected with the positioning ring tube 1, the rotating shaft is rotated. At this time, the synchronous gear 9 drives the two racks 10 to move synchronously. At this time, the two positioning ring tubes 1 are closed synchronously, which can gradually align the tower, and then the tower can be quickly hoisted and docked, thereby realizing the rapid installation of the tower.

[0044] Furthermore, the end of the rotating shaft passes through the transmission box 8 and is fixedly provided with a driving block 11 , and the driving block 11 is provided with a hexagonal groove 12 .

[0045] Specifically, in order to facilitate the driving of the synchronous shrinkage device 3, an electric tool and an Allen wrench can be used to drive the driving block 11 to rotate. At this time, the hoisted tower and the fixed tower are quickly aligned under the contraction of the positioning ring tube 1, and can be quickly connected and installed by bolts.

[0046] To prevent the rack 10 from falling off the synchronous gear 9, a limit block 13 is provided at the end of the rack 10 away from the positioning hook 2, and the limit block 13 is located inside the transmission case 8. When the limit block 13 moves to the synchronous gear 9, it can limit the further movement of the rack 10, effectively ensuring the stability of the synchronous shrinker 3.

[0047] Compared with the prior art, the present invention has at least the following beneficial effects:

[0048] The present invention utilizes the misalignment of the positioning hook and the tower to achieve rapid connection and disassembly of the positioning hook and the tower, facilitates rapid docking between the positioning ring and the positioning hook, and simultaneously cooperates with the synchronous shrinker to achieve rapid docking between the hoisted tower and the installed tower, greatly improving the installation efficiency of the tower.

[0049] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
