Improved tail slide hoist and tower body turning system

Abstract

The application discloses an improved tailing hoisting device and a tower body overturning body system. The improved tailing hoisting device comprises a hook body provided with a tailing hook groove for horizontally embedding a tower bottom. A main lifting lug is fixedly connected to the right side of the curved part of the hook body, and side lifting lugs are fixedly connected to the front and back sides of the curved part of the hook body. One main lifting lug and two side lifting lugs form three connecting points for connecting three cable wind ropes respectively. The three cable wind ropes are connected with the main lifting lug and the two side lifting lugs. The embedding process is controlled by the three cable wind ropes during embedding of the tailing hook into the tower bottom, so that the problem that the hook body of the tailing hook shakes due to wind direction change during the tailing hook fixing process is solved, and the embedding process is difficult to control.

Description

Technical Field

[0001] This utility model relates to an improved tail-running hoisting device and tower turning system, belonging to the field of offshore wind power hoisting technology. Background Technology

[0002] Fixed offshore wind turbine towers or pipe piles are very large in size and weight. The towers need to be laid flat on transport ships to the wind farm area, and then lifted and erected by the coordinated operation of lifting beams and tail clamps (see Chinese Patent Publication No. CN118978082A).

[0003] Two hooks are required for hoisting wind turbine towers. The main hook connects to the lifting beam, while the auxiliary hook connects to a tailing clamp used for support. The lifting beam is connected to the tower's lifting lugs via a wire rope. The tailing clamp slowly embeds the hook into the bottom of the tower to prevent friction or collision between the lifting beam and the tower's base during hoisting. During the tailing clamp's installation, changes in wind direction can cause the hook to sway, making the embedding process difficult to control and consequently hindering tower installation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides an improved tail-running hoisting device and tower turning system.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides an improved tail-running hoisting device, comprising: The hook body is equipped with a tail clamp hook groove for horizontally embedding into the bottom of the tower cylinder.

[0007] The top surface of the hook body has an eye plate that connects to the auxiliary hook.

[0008] A main lifting lug is fixedly connected to the right side of the curved section of the hook body, and side lifting lugs are fixedly connected to both the front and rear sides of the curved section of the hook body. One main lifting lug and two side lifting lugs form three connection points for connecting three guy ropes respectively. The hook body located at the eye plate has a counterweight placed on it via a fixedly connected support frame.

[0009] The hook body below the slot of the tail clamp is reinforced with a trapezoidal plate.

[0010] A tower tilting system includes: Beam body; Eye plates are fixed at the top of both ends of the beam to form a lifting beam; the eye plates have fixed shafts that are connected to the main unit's hook cable. The bottom of both ends of the beam is equipped with fixing bolts, which are connected to the lifting lugs on both sides of the tower via cables. It also includes the aforementioned improved tail-running hoisting device, in which the tail-running clamp groove of the hook body is horizontally embedded into the bottom of the tower cylinder, and each main lifting lug and two side lifting lugs are connected to three guy ropes.

[0011] The beam is reinforced by ribs.

[0012] The beneficial effects of this utility model are as follows: three guy ropes are connected to one main lifting lug and two side lifting lugs. During the process of embedding the tail clamp into the bottom of the tower, the embedding process is controlled by the three guy ropes, which solves the problem that the hook of the tail clamp will shake due to changes in wind direction during the fixing of the tail clamp, and the embedding process is difficult to control.

Detailed Implementation

[0014] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0015] like Figures 1 to 5 As shown.

[0016] An improved tail-running hoisting device according to this application includes: The hook body 12 is provided with a tail clamp hook groove 14, and the tail clamp hook groove 14 is horizontally embedded in the bottom of the tower cylinder.

[0017] The top surface of the hook body 12 has an eye plate 10 connected to the auxiliary hook; the right side of the curved part of the hook body 12 is welded and fixedly connected to the main lifting lug 13, and the front and rear sides of the curved part of the hook body 12 are welded and fixedly connected to the side lifting lugs 15. One main lifting lug 13 and two side lifting lugs 15 are respectively connected to three guy ropes 16. During the process of embedding the tail clamp into the bottom of the tower, the embedding process is controlled by controlling the three guy ropes 16, which solves the problem that the hook body of the tail clamp will shake due to the change of wind direction during the fixation of the tail clamp, and the embedding process is difficult to control.

[0018] After connecting the lifting beam and tail clamp to the tower, slowly raise the cable until the tower is raised. After confirming that there are no abnormalities in the lifting status, continue to raise the main hook of the lifting beam until the tower is erected. The tail clamp will automatically detach from the bottom of the tower under the action of gravity, completing the tower turning operation.

[0019] The hook body 12 located at the eye plate 10 is provided with a counterweight 8 by a fixedly connected support frame 9. This ensures that when the eye plate 10 is connected to the auxiliary hook by a lifting cable, the counterweight 8 uses the eye plate 10 as a lever point to keep the hook body 12 horizontal.

[0020] The hook body 12 below the hook groove 14 of the tail clamp is reinforced by a trapezoidal plate 11.

[0021] This application discloses a tower tilting system, comprising: The beam body 4 is made of steel and is reinforced by ribs 6.

[0022] The top of both ends of the beam body 4 are welded and fixed with eye plates 5 to form a lifting beam; the eye plates 5 have fixed shafts 3 that are connected to the main machine hook cable; the fixed shafts 3 are connected to the main machine hook at each end by two cables, for a total of four cables.

[0023] The bottom of both ends of the beam body 4 is provided with fixing bolts 2, and the fixing bolts 2 are connected to the lifting lugs on both sides of the tower 17 by cables.

[0024] It also includes the aforementioned improved tail-running hoisting device, in which the tail-running clamp hook groove 14 of the hook body 12 is horizontally embedded into the bottom of the tower cylinder 17, and the main lifting lug 13 and the two side lifting lugs 15 are respectively connected to three guy ropes 16.
