Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine hub hoisting, and in particular to a universal hoisting device for wind turbine hubs. Background Technology

[0002] Currently, most mainstream wheel hub lifting devices on the market adopt a split-type lifting base structure, using multiple independent lifting bases that match the bolt holes on the top of the wheel hub and are rigidly fixed with high-strength bolts. However, this design suffers from problems such as non-universality, low operating efficiency, safety hazards, and high management costs. Different machine models have significantly different wheel hub sizes, bolt hole layouts, and load-bearing requirements, necessitating custom-made lifting bases for each model, making cross-model reuse impossible; a single lifting operation takes more than 40 minutes, impacting production line turnover efficiency; personnel working at height face the risk of falls, and operational errors with pneumatic wrenches may cause parts to fall; wheel hubs from multiple suppliers are compatible with different lifting bases, increasing the difficulty of warehouse management. Therefore, an innovative structural design is urgently needed to achieve cross-model universality for the lifting device, overcoming the limitations of existing technology. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a universal hoisting device for wind turbine hubs, which can effectively solve the problems of poor versatility, low operating efficiency, many safety hazards and high management costs of existing hub hoisting devices.

[0004] The objective of this utility model can be achieved by adopting the following technical solutions:

[0005] A universal lifting device for wind turbine hubs includes a hook assembly, a support assembly, a central guide column, side guide rods, a gripper assembly, and a gripper support seat. The top of the hook assembly is connected to a lifting device, and its bottom is connected to the top of the central guide column. The bottom end of the central guide column passes through the center of the support assembly and extends downward. The gripper support seat is located at the bottom end of the central guide column. The side guide rod is parallel to the central guide column, with its top end connected to the bottom of the hook assembly and its bottom end passing through the side guide hole of the support assembly and extending downward. The side guide rod provides a limiting and guiding function for the support assembly. There are three gripper assemblies, evenly distributed around the central guide column along the circumference and located between the support assembly and the gripper support seat. Each gripper assembly has a J-shaped structure. The top end of the long rod of the J-shaped structure passes through the support assembly and is hinged to the top of the support assembly. The hook-shaped part of the J-shaped structure faces outward. The three gripper assemblies hook onto the edge of the hub, thereby achieving the lifting of the hub.

[0006] Furthermore, the hook assembly includes a hook support plate and a hook disposed on the top of the hook support plate.

[0007] Furthermore, the support assembly includes an upper support plate, a lower support plate, multiple connecting plates, and support legs. The upper and lower support plates are arranged parallel to each other vertically and are connected by multiple connecting plates. A central guide hole for penetrating the central guide post is provided at the center of the upper and lower support plates, and a side guide hole for penetrating the side guide rod is provided on the upper and lower support plates next to the central guide hole. There are three support legs, which are arranged circumferentially around the bottom of the lower support plate. Three through holes are formed on the lower support plate, and the three through holes correspond one-to-one with three gripper assemblies. The top end of the long rod of the J-shaped structure of each gripper assembly passes through the corresponding through hole and is hinged to the top of the upper support plate.

[0008] Furthermore, the gripper assembly includes a gripper connector and a gripper. The gripper connector has a J-shaped structure, with the top end of the long rod of the J-shaped structure passing through the support assembly and hinged to the top of the upper support plate of the support assembly. The hook-shaped part of the J-shaped structure is arranged facing outward. The gripper has a U-shaped structure and is fixed to the end of the hook-shaped part of the J-shaped structure. The gripper hooks onto the edge of the wheel hub, thereby achieving the lifting of the wheel hub.

[0009] Furthermore, the gripper is provided with a buffer pad to prevent damage to the wheel hub.

[0010] Furthermore, there are two side guide rods.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] 1. Universal lifting capability: This utility model uses the hook-shaped parts of three gripper components to hook onto the edge of the wheel hub, which can adapt to the size and shape characteristics of wheel hubs of different models, thereby realizing the lifting and transportation of various wheel hubs and achieving the purpose of universal lifting and transportation.

[0013] 2. Reduced time occupation: This utility model abandons the traditional method of requiring manual climbing to the top of the wheel hub to install multiple lifting seats and tighten a large number of bolts. It adopts a gripper assembly hook lifting method, which can complete the lifting of the wheel hub in a short time, greatly reducing the time occupied by personnel preparation, installation and vehicle operation.

[0014] 3. Reduced safety risks: This utility model eliminates the need for dangerous operations such as installing bolts at heights, effectively avoiding safety risks such as people falling from heights and tools falling. Attached Figure Description
