Description
Technical Field
[0001] This utility model belongs to the technical field of wind turbine hub melting and processing equipment, and particularly relates to a special lifting tool for wind turbine hub melting and processing. Background Technology
[0002] The wind turbine hub is one of the core components of a wind turbine generator set. Its main function is to connect the blades and the main shaft, convert the wind energy captured by the blades into mechanical energy, and then transmit it to the generator through the main shaft to generate electricity. After the wind turbine hub is smelted and formed, the hub needs to be polished and then painted on the surface.
[0003] Due to their weight, conventional hoisting methods use telescopic binding for lifting. When processing the surface, it is necessary to switch directions and then process the other side of the wheel hub while maintaining the binding state. The ropes hinder the processing, resulting in the need for repeated binding when processing wind turbine wheel hubs with conventional hoisting equipment.
[0004] To address this issue, we propose a specialized lifting tool for the smelting and processing of wind turbine hubs. Utility Model Content
[0005] The purpose of this utility model is to solve the problem of repeated binding required for processing wind turbine hubs using conventional hoisting equipment, and to propose a special hoisting tool for the melting and processing of wind turbine hubs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A specialized lifting device for the smelting and processing of wind turbine hubs includes an mounting ring, a hanger, and a positioning plate. The lower end of the hanger is fixedly connected to the upper part of the mounting ring, and the upper part of the positioning plate is slidably installed inside the mounting ring. A spring is provided between the mounting ring and the positioning plate, with one end of the spring fixedly connected to the positioning plate and the other end of the spring fixedly connected to the mounting ring. The hook is hung on the hanger, and the device is lifted upwards to the target wind turbine hub. The positioning plate is inserted into the target wind turbine hub, positioning the mounting ring at the mounting opening of the target wind turbine hub. Then, the mounting ring is installed on the target hub using screws. The device is then lifted again, and the target wind turbine hub is lifted upwards using the device, avoiding repeated binding of the hub.
[0008] Preferably, the mounting ring includes a ring body with a mounting hole cut out on it, and a guide rod is fixedly connected inside the ring body. The guide rod guides the positioning piece to slide, and the spring force acts on the positioning piece. After the positioning piece is inserted into the target wind turbine hub, the spring force of the positioning piece acts on the positioning piece to position the ring body, facilitating the alignment of the mounting ring with the mounting opening of the target hub.
[0009] Preferably, the hanger includes a frame, and a main lifting ring is fixedly connected to the upper end of the frame. The lifting ring is hung on the main lifting ring, and the main lifting ring is lifted upwards. The main lifting ring then lifts the frame upwards, causing the frame to act upwards on the ring, facilitating the lifting and installation of the ring.
[0010] Preferably, the hanger further includes sub-lifting rings, which are symmetrically and fixedly connected to the side of the frame. The sub-hook is hung inside the sub-lifting ring to control the hanger, prevent it from rotating, and improve the stability of the hanger during lifting operations.
[0011] Preferably, the positioning piece includes a stop bar and a guide plate, with the lower end of the stop bar fixedly connected to the upper end of the guide plate. The stop bar is guided to slide by a guide rod, and the spring force acts outward on the positioning piece, causing the positioning piece to act within the target wheel hub. This aligns the ring with the mounting opening of the target wheel hub, facilitating the positioning and installation of the ring and the target wheel hub.
[0012] Preferably, the positioning piece further includes a slide block, the lower end of which is fixedly connected to the upper end of the stop bar. The slide block increases the sliding contact range between the positioning piece and the guide rod, improving the stability of the positioning piece's sliding direction.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. Hang the hook on the hanger, lift the device upwards, and lift the device onto the target wind turbine hub. Use the positioning plate to insert into the target wind turbine hub so that the mounting ring is positioned on the mounting opening of the target wind turbine hub. Then, use screws to install the mounting ring onto the target hub. Lift the device again and lift the target wind turbine hub upwards through the device to avoid repeatedly binding the hub.
[0015] 2. The positioning plate is guided to slide by the guide rod, and the spring force acts on the positioning plate. After the positioning plate is inserted into the target wind turbine hub, the spring force of the positioning plate acts on the positioning plate to position the positioning ring body, so that the installation ring is aligned with the installation opening of the target hub.
[0016] 3. Hang the lifting ring on the main lifting ring, lift the main lifting ring upwards, and lift the frame upwards through the main lifting ring, so that the frame acts upwards on the ring, making it easier to lift and install the ring.
[0017] 4. Hang the sub-hook inside the sub-shaft to control the gantry, prevent the gantry from rotating, and improve the stability of the gantry lifting operation.
[0018] 5. The guide rod guides the sliding of the stop bar, and the spring force acts outward on the positioning plate, so that the positioning plate acts inside the target wheel hub, thereby aligning the ring body with the mounting opening of the target wheel hub, which facilitates the positioning and installation of the ring and the target wheel hub.
