[0025] Combined with Figure 1 and Figure 2 The top of the second limiting component 5 is rotatably connected to a swivel seat 6, and the swivel seat 6 is connected to a lifting component 7. The clamping member 2 is rotatably connected to the other end of the lifting component 7. The lifting component 7 includes a first hinge rod 17 rotatably connected to the swivel seat 6, and the other end of the first hinge rod 17 is hingedly provided with a second hinge rod 18. The other end of the second hinge rod 18 is rotatably connected to a connecting seat 19, and the connecting seat 19 is connected to the clamping member 2.

[0026] Through the coordinated arrangement of the base cylinder, tower 1, clamping member 2, first limiting assembly 3, second limiting assembly 5, walking assembly 4, slewing seat 6 and lifting assembly 7 in the above structure, it is convenient to temporarily connect the device to the installed base cylinder or tower 1 through the first limiting assembly 3 and the second limiting assembly 5 so as to assist the subsequent lifting operation of the tower 1, thereby reducing the occupied area during operation; through the arrangement of the lifting assembly 7, it is convenient to lift the tower 1 to be lifted, and through the coordinated arrangement of the first hinge 17, the second hinge 18, the connecting seat 19 and the rigid clamping member 2, it is convenient to limit the lifting of the tower 1 to be lifted through the rigid clamping member 2, so as to reduce the influence of the offshore wind resistance on the lifting of the tower to be installed.

[0027] Embodiment 2

[0028] Based on the first embodiment, combined with the attached Figure 4The first limiting assembly 3 is connected to a walking assembly 4, and the walking assembly 4 includes a motor connected to the first frame 8. A worm is connected to the power output end of the motor, and a worm wheel is connected to the worm. A gear 16 is coaxially connected to the worm wheel. A rack 15 is relatively connected to the middle part of the second frame 11, and the rack 15 is meshed with the gear 16.

[0029] The arrangement of the walking assembly 4 in the above structure facilitates the device to climb upwards, and after a section of the tower 1 is installed, the walking assembly 4 can be moved thereto for the hoisting work of the next section of the tower 1.

[0030] The specific usage is as follows:

[0031] First, the first limiting claws 9 on both sides of the top and bottom ends of the first frame 8 are driven by the driving member to approach each other, so as to facilitate the clamping of the installed base tube or tower tube 1, so that the first frame 8 is temporarily positioned. Such driving members that can drive components to approach or move away from each other are mature products, and the implementation methods are various, which will not be repeated here; the second frame 11 is slidably connected to the first frame 8 through the matching arrangement of the fixed block 10, the sliding hole 13, and the sliding bar 12. Similarly, when the second limiting claws 14 at the top and bottom ends of the second frame 11 are driven by the driving member to approach each other, it is convenient to temporarily position the second frame 11. When the second frame 11 is positioned, the hoisting operation can be performed at this time; the setting of the lifting assembly is convenient for hoisting the tower 1 to be hoisted, and the first hinge rod 17, the second hinge rod 18, the connecting seat 19 and the rigid clamping member 2 are arranged to facilitate the limited hoisting of the tower 1 to be hoisted by the rigid clamping member 2, so as to avoid the flexible hoisting device hoisting the tower 1 and causing shaking due to the wind resistance at sea, thereby affecting the stability of the lifting assembly 7 or the installed tower 1. At the same time, since the tower is still under the hoisting of the external hoisting device, the clamping member and the device as a whole of the utility model do not bear much force;

[0032] Then, the tower 1 to be hoisted is lifted to the top of the installed tower 1 with the assistance of the lifting assembly 7, and then the tower 1 to be hoisted is rotated to the installed tower 1 through the slewing seat 6 so that the tower 1 to be installed and the installed tower 1 are aligned on the axis, and then the tower 1 to be installed is finely adjusted in height by driving the lifting assembly 7 or the second frame 11 to achieve end face alignment for installation;

[0033] Finally, when the above-mentioned hoisting tower 1 has been installed, by starting the motor, the motor has a self-locking function, the motor drives the gear 16 to rotate, the gear 16 drives the rack 15 to drive the second frame 11 to rise and fall, so that after a tower 1 is installed, the second frame 11 rises to the tower 1 that has just been installed, and then the second limit claw 14 is used to temporarily position the second frame 11, and then the first limit claw 9 is released, and then the motor is started, and the motor drives the gear 16 to drive the first frame 8 to move up to the tower 1, and the first limit assembly 3, the second limit assembly 5 and the walking assembly 4 are coordinated to facilitate the device to move upward in sequence to complete the auxiliary hoisting work of towers 1 at different heights.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0036] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
