Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a lifting device for welding accessories inside a tower. Background Technology

[0002] The tower is an important component of a wind turbine generator set. It is mainly used to support the nacelle and blades to achieve the optimal windward height, while resisting the swaying and vibration of the unit and ensuring the overall safe operation. In order to weld the accessories inside the tower, the accessories need to be lifted and transported by a lifting device.

[0003] Application number CN202222696574.X discloses a lifting device for welding internal accessories in a tower, including a lifting platform. A bracket is installed at the top of the lifting platform, and three sets of positioning pins are evenly fixed on the bracket. A central frame is inserted into the positioning pins... This solves the problem that the transportation of internal accessories usually requires the use of trolleys or manual handling, which requires multiple groups of workers to cooperate, is time-consuming and labor-intensive, and it is not easy to maintain stability when moving trolleys or manually. This type of lifting device can only be used when fixed on the ground and is not suitable for installation inside towers of different models, resulting in poor performance of the lifting device. In addition, it lacks a braking structure and cannot avoid emergencies, resulting in poor safety performance of the lifting device. Utility Model Content

The rotating shaft 203 is located at the output end of the reduction motor 202, and one end of the rotating shaft 203 passes through the interior of the take-up roller 201. The reduction motor 202 and the rotating shaft 203 can drive the take-up roller 201 to rotate, which facilitates the winding and unwinding of the cable 204. The cable 204 is located on the outside of the take-up roller 201.

[0027] Please refer to this carefully. Figure 2 and Figure 3An adjustment groove 101 is provided in the middle of the interior of the mounting frame 1. Limiting bolts 106 are provided at the four corners of the top of the mounting frame 1. The limiting bolts 106 can limit the movement between the telescopic frame 103 and the mounting frame 1. A hook 205 is provided at one end of the cable 204 for easy hanging of accessories. Multiple sets of guide rollers 206 are provided at the bottom of the interior of the housing 2. A slot 207 is provided in the middle of the bottom of the housing 2 for easy winding and unwinding of the cable 204. The rotating shaft 203 is located far from...

[0028] Please refer to this carefully. Figure 1 and Figure 3 The top of the housing 2 is welded to the bottom of the mounting frame 1. Bearings are provided on one side of each of the two sets of telescopic grooves 102, and both ends of the bidirectional screw 105 pass through the bearings. The bearings make the rotation of the bidirectional screw 105 more stable. The telescopic frame 103 is movably connected to the mounting frame 1 via the telescopic grooves 102. The telescopic grooves 102 allow for telescopic adjustment between the telescopic frame 103 and the mounting frame 1. A threaded hole matching the bidirectional screw 105 is provided on one side of the telescopic frame 103, serving as a limit adjustment. The two sets of telescopic frames 103 can be adjusted in opposite directions, facilitating the installation of the lifting device. (The last sentence appears to be incomplete and possibly refers to a different topic.) The machine 202 is detachably connected to the housing 2 by mounting bolts, so that the geared motor 202 can be installed inside the housing 2. The take-up roller 201 is connected to the geared motor 202 through the rotating shaft 203, so that the geared motor 202 can drive the take-up roller 201 to rotate, which can be used to wind up and unwind the cable 204. A bearing is provided on one side of the housing 2, and one end of the rotating shaft 203 passes through the bearing, so that the rotation of the rotating shaft 203 is more stable.

[0029] Please refer to this carefully. Figure 2 and Figure 3A rotating block is provided on the outer side of the bidirectional screw 105 at the position of the adjustment groove 101. The rotating block has a hexagonal structure, which facilitates the rotation of the bidirectional screw 105. The four corners of the top of the mounting bracket 1 are provided with threaded holes that match the limit bolts 106, which can adjust the relationship between the limit bolts 106 and the mounting bracket 1 and limit the relationship between the telescopic bracket 103 and the mounting bracket 1. The brake wheel 3 has a mounting hole inside, and the brake wheel 3 is detachably connected to one end of the rotating shaft 203 through the mounting hole, so that the brake wheel 3 and one end of the rotating shaft 203 can be installed. The electric push rod 302 is detachably connected to the mounting shell 301 through the fixing bolt, so that the electric push rod 302 can be installed at the bottom of the mounting shell 301. The bottom of the brake block 303 is provided with a connecting block, and the telescopic end of the electric push rod 302 is connected to the connecting block, so that the electric push rod 302 can drive the brake block 303 to lift and adjust, and can adjust the brake block 303 to contact the brake wheel 3.

[0030] Working Principle: Before use, the lifting device is moved to the desired location. A wrench is used to clamp the outside of the rotating block, and the bidirectional screw 105 is rotated. The bidirectional screw 105 engages with the threaded holes inside the two sets of telescopic frames 103, allowing the two sets of telescopic frames 103 to drive the anti-slip block 104 to adjust in opposite directions. The lifting device can be installed inside different towers for use. The limiting bolt 106 can limit the movement between the telescopic frame 103 and the mounting frame 1, making the installation and use of the lifting device more stable. When in use, the power is turned on, and the attachment can be hung through the hook 205. The geared motor 202 and the rotating shaft 203 drive the winding roller 201 to rotate, which can wind and unwind the cable 204, thereby lifting the attachment. The rotating shaft 203 can keep the winding roller 201 and the brake wheel 3 rotating synchronously. In case of emergency, the electric push rod 302 can drive the brake block 303 to adjust its height and make the brake block 303 in close contact with the brake wheel 3 until it stops, thus making the use of the lifting device safer.
