Description

Technical Field

[0001] The invention belongs to the field of wind power converter power module testing, and in particular relates to a wind power converter power module disassembly and assembly auxiliary tooling. Background Art

[0002] As wind turbine converter power levels increase, more and more power modules are connected together. Power modules can often weigh 100kg or more, making manual lifting unsafe and inefficient. Testers frequently need to disassemble and assemble modules for R&D prototype testing. Currently, there is no convenient tool to assist testers in disassembling and assembling power modules anytime, anywhere. However, this need is growing. Whether in-house or during third-party testing, module replacement is common. Assisting testers in disassembling and assembling wind turbine converter power modules replaces manual lifting or the complex and inefficient use of bulky forklifts or forklifts. Summary of the Invention

[0004] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0005] A wind power converter power module disassembly and assembly auxiliary tooling includes a lifting assembly, an installation assembly, and a sliding assembly. The installation assembly includes a mounting plate, which is fixed to the top of the wind power converter. A slide groove is provided in the mounting plate, and the sliding assembly is installed in the slide groove. The lifting assembly includes a large roller, a small roller, a transmission assembly, and a lifting wire. The large roller is installed on the sliding assembly, the transmission assembly is connected between the large roller and the small roller, the large roller is connected to the lifting wire, and the end of the lifting wire away from the large roller is connected to the power module of the wind power converter. A handle is installed on the small roller.

[0006] Furthermore, the installation assembly also includes a limit plate, a connecting wire, and a chassis grab hook. There are two limit plates, which are fixed at both ends of the installation plate respectively. One end of the limit plate away from the installation plate is connected to the chassis grab hook through a connecting wire.

[0007] Furthermore, a connecting rod is connected between the large roller and the small roller. There are two connecting rods, which are arranged on both sides of the large roller. One end of the connecting rod is rotatably connected to the rotating shaft of the large roller through a sleeve, and the other end of the connecting rod is rotatably connected to the rotating shaft of the small roller through a sleeve.

A mounting rod is fixed to the end of the sliding plate close to the large roller. There are two mounting rods, and a rotating shaft is installed between the two mounting rods. The large roller is rotatably connected to the rotating shaft.

[0009] Furthermore, two pulleys are installed on both sides of the sliding plate, one of the pulleys is installed at an end of the sliding plate away from the large roller, and the other roller is spaced apart from one of the pulleys.

[0010] Furthermore, blocks are fixed at both ends of the openings reserved for the mounting plate to prevent the pulley from detaching from the mounting plate.

[0011] Furthermore, there are two lifting wires, which are respectively arranged at both ends of the large drum. The large drum is provided with a transmission wire groove corresponding to the lifting wires. One end of the lifting wire is arranged in the transmission wire groove, and the other end is connected to the power module.

[0012] Furthermore, one end of the lifting wire away from the large roller is connected to a hook, and the hook is connected to the power module.

The lifting assembly and the installation assembly are arranged in conjunction with each other, and one person can use this tool to complete the disassembly and assembly of a power module weighing about 100 kg.

[0015] (2) The sliding assembly facilitates the left and right movement of the module after it is hoisted to a certain height, so that the power module and the converter body groove are seamlessly connected.

[0016] (3) The connecting rod is rotatably connected to the large roller and the small roller, and the height of the handle can be adjusted according to the height of the staff, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
