[0002] In the field of wind power generation, wind turbine tower hoists, as key equipment, play a vital role in improving the work efficiency of wind turbine operators and maintenance personnel. With the rapid development of the wind power industry, wind turbine units are showing a significant trend towards larger size, ultra-high towers, and diversified tower types.

[0003] The existing lifting equipment for concrete wind turbine towers typically uses wire rope guide hoists, which carry construction personnel through loading platforms or cabins.

[0004] However, existing wire rope guide hoists typically require professional maintenance personnel to inspect the wire ropes and other components during operation, making it impossible to monitor the wire rope's condition and damage in real time, thus increasing labor costs. Therefore, a hoisting device for concrete wind turbine towers is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lifting device for concrete wind turbine towers, which aims to improve the problem that the existing technology cannot monitor the usage status and damage of wire ropes in real time.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a lifting device for concrete wind turbine towers, comprising a frame, a top frame fixedly connected to the top of the frame, a flap hinged to the outer wall of the top frame, a bolt threaded to the top of the flap, a motor fixedly connected to the inner wall of the top frame, a moving gear fixedly connected to the output end of the motor, a ring gear meshing with the inner side of the outer wall of the moving gear, a retaining ring fixedly connected to the bottom of the ring gear, a camera fixedly connected to the inner arc surface of the ring gear, a car connected to the frame via a lubrication assembly, a frame fixedly connected to the outer wall of the car, and a steel wire rope fixedly connected to the top of the frame.

[0017] As a further description of the above technical solution:

[0018] The bottom of the frame is in contact with the inner wall of the bottom of the frame.

[0019] As a further description of the above technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a lifting device for concrete wind turbine towers, comprising a frame 1. The frame 1 is welded from high-strength steel, possessing good load-bearing capacity and deformation resistance. It can be directly fixed to preset installation points on the inner wall of the tower, providing stable support for the entire lifting system. A top frame 2 is fixedly connected to the top of the frame 1. The top frame 2 provides an overhead space for the motor 5, moving gear 6, ring gear 7, and camera 9. A flap 3 is hinged to the outer wall of the top frame 2. The flap 3 is used to unfold the top frame 2 for convenient manual maintenance. A bolt 4 is threadedly connected to the top of the flap 3. The bolt 4 is used to thread the flap 3, allowing manual maintenance to be performed by simply loosening the bolt 4 to disengage the flap 3. The flip-up panel 3 can be opened. A motor 5 is fixedly connected to the inner wall of the top frame 2. The motor 5 is existing technology and is used to reciprocate the moving gear 6, causing the two sets of ring gears 7 to rotate one revolution and then rotate one revolution in the opposite direction, thereby achieving the effect of rotating around the steel wire rope 12. The output end of the motor 5 is fixedly connected to the moving gear 6, which is used to transmit the power of the motor 5 and drive the two sets of ring gears 7 to rotate synchronously. The inner side of the outer wall of the moving gear 6 meshes with the ring gear 7. The retaining ring 8 at the bottom of the ring gear 7 cooperates with the rotating structure of the bottom inner wall of the top frame 2, which can realize the rotational motion around its own axis, thereby driving the camera 9 to rotate in a circle. The retaining ring 8 is fixedly connected to the bottom of the ring gear 7. The retaining ring 8 is a ring structure and is made of wear-resistant casting. Made of iron, its inner diameter matches the outer diameter of the ring gear 7, and it is fixed to the bottom of the ring gear 7 by welding. The function of the retaining ring 8 is to restrict the vertical displacement of the ring gear 7, ensuring that it can only rotate on the horizontal plane. The inner arc surface of the ring gear 7 is fixedly connected to the camera 9. The camera 9 is a high-definition night vision camera with 360-degree rotation shooting function, which can monitor the operation of the wire rope 12 and whether the wire rope 12 is damaged in real time during the operation of the lifting equipment. The camera 9 can also be connected to the control panel inside the car 10 through wires, so that the operator can view the screen. The frame 1 is connected to the car 10 through a lubrication assembly. The car 10 is existing technology and will not be described in detail. It is used to support... The elevator car 10 is equipped with a frame 11 fixedly connected to its outer wall. The frame 11 enhances the overall structural strength of the car 10 and provides connection points for the wire rope 12. The top of the frame 11 is fixedly connected to the wire rope 12, which is a multi-strand galvanized steel rope with high strength and tensile strength. The top is connected to a drag and rewind mechanism to realize the winding and unwinding of the wire rope 12, thereby driving the car 10 to rise and fall. The bolt 4 passes through and is inserted into the top inner wall of the top frame 2. The retaining ring 8 is rotatably connected to the bottom inner wall of the top frame 2. The wire rope 12 passes through the inner wall of the top frame 2. The front of the car 10 is in contact with the inner wall of the frame 1, and the bottom of the frame 11 is in contact with the bottom inner wall of the frame 1.

[0032] Reference Figures 1-3The lubrication assembly includes a reinforcing rib 14, which consists of two sets of long strip steel structures that provide mounting support for the pulley 15. The reinforcing rib 14 is fixedly connected to the outer wall of the car 10. The pulley 15 is rotatably connected to the inner wall of the reinforcing rib 14. The pulley 15 is a rolling bearing type, with the wheel body made of high-strength plastic material and the inner wall inlaid with metal bearings to reduce the frictional resistance when the pulley 15 rotates. The inner wall of the frame 1 is provided with a guide groove 13, which is a vertical long strip groove. Its cross-sectional shape matches the shape of the pulley 15 wheel body to ensure that the pulley 15 can slide stably in the groove. The inner wall of the guide groove 13 is coated with special grease to further reduce the friction coefficient between the pulley 15 and the groove wall. The pulley 15 is slidably connected to the inner wall of the guide groove 13.

[0033] Working principle: When the equipment is started, the motor 5 fixed to the inner wall of the top frame 2 begins to work, and the output end of the motor 5 drives the moving gear 6 to reciprocate. Since the inner side of the outer wall of the moving gear 6 meshes with the ring gear 7, the moving gear 6 transmits power to the two sets of ring gears 7, causing the ring gears 7 to rotate synchronously. At this time, the retaining ring 8 at the bottom of the ring gear 7 cooperates with the rotation structure of the bottom inner wall of the top frame 2, restricting the vertical displacement of the ring gear 7 and ensuring that the ring gear 7 rotates stably only around its own axis on the horizontal plane, providing a power basis for the circular motion of the subsequent monitoring components. With the cooperation of the power system, the external drag and rewind mechanism starts to operate, performing the winding and unwinding operation on the steel wire rope 12 connected to the top. The bottom of the wire rope 12 is connected to the top of the frame 11 fixed to the outer wall of the car 10, and the wire rope 12 passes through the inner wall of the top frame 2. When the wire rope 12 is wound up, it pulls the frame 11 upward, thereby driving the car 10 to rise. When the wire rope 12 is released, the car 10 slowly descends under its own weight and the weight it bears, thus meeting the lifting and lowering needs of personnel. During equipment operation, the camera 9 fixed on the inner arc surface of the ring gear 7 moves synchronously with the circumferential rotation of the ring gear 7. Since the ring gear 7 is driven by the driven gear 6 to perform reciprocating circumferential rotation, the camera 9 can achieve comprehensive circumferential monitoring of the wire rope 12, capturing the operation status of the wire rope 12 and whether there is any damage. If it is necessary to inspect the motor 5, the driven gear 6, the ring gear 7, or the camera 9, the operator can loosen the bolt 4 on the top of the flip plate 3 to disengage the bolt 4 from the flip plate 3, and then open the flip plate 3 hinged to the outer wall of the top frame 2 to perform inspection operations on the internal components of the top frame 2.

[0034] During the lifting and lowering of the car 10, the reinforcing ribs 14 fixed to its outer wall provide support. The pulleys 15 rotatably connected to the inner wall of the reinforcing ribs 14 cooperate with the guide grooves 13 opened on the inner wall of the frame 1. The pulleys 15 slide on the inner wall of the guide grooves 13, providing guidance for the lifting and lowering of the car 10 and preventing deviation. At the same time, the special grease applied to the inner wall of the guide grooves 13, combined with the bearing structure of the pulleys 15, can effectively reduce the coefficient of friction between the pulleys 15 and the groove wall of the guide grooves 13, reducing the frictional resistance between the two, making the lifting and lowering process of the car 10 more stable and smooth, reducing equipment wear, and extending the service life of components.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
