Description

Technical Field

[0001] This utility model relates to the field of wind turbine maintenance technology, specifically to a tooling for disassembling the electromagnetic brake bushing of a wind turbine pitch motor. Background Technology

[0002] During the replacement of the electromagnetic brake on the DC pitch motor of a wind turbine, the small gap between the electromagnetic brake bushing and the motor makes it impossible to use ordinary puller tools to clamp the bushing for disassembly. Furthermore, the electromagnetic brake bushing, due to its long service life, is corroded, making disassembly exceptionally difficult. A significant amount of time is required to complete the disassembly and replacement. Utility Model Content

[0003] This utility model provides a tooling for disassembling the electromagnetic brake bushing of a wind turbine pitch motor, aiming to solve the problems in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A tooling for disassembling an electromagnetic brake bushing of a wind turbine pitch motor includes a crossbeam, a drive unit, and multiple claw assemblies. The multiple claw assemblies are evenly spaced around the crossbeam and can move up and down and move horizontally and be positioned. The multiple claw assemblies are used to hold the bushing to be disassembled. The drive unit is connected to the crossbeam and is used to drive the crossbeam and the multiple claw assemblies to move upward to pull the bushing to be disassembled upward.

[0006] The beneficial effects of this utility model are as follows: During use, the crossbeam is placed above the bushing to be disassembled, and then the positions of multiple claw components are manually adjusted so that the multiple claw components hold the bushing to be disassembled. Finally, the drive component is used to drive the crossbeam and multiple claw components to move upward to pull the bushing upward, thereby realizing the disassembly of the bushing. The disassembly is convenient.

[0007] This utility model has a simple structure and reasonable design, and can quickly disassemble the electromagnetic brake bushing of the pitch motor, which greatly shortens the time required to replace the electromagnetic brake and improves work efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the crossbeam is provided with a plurality of vertically penetrating openings at even intervals, the plurality of openings being circumferentially distributed and extending radially along the circumference they form; the plurality of claw assemblies are respectively movable vertically and positioned at the plurality of openings, and are respectively movable along the direction from one end of the opening to the other end.

[0010] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The multiple openings on the crossbeam facilitate the assembly of the multiple claw components. At the same time, the multiple claw components cooperate with the multiple openings to adjust the position of the multiple claw components, which is convenient.

[0011] Furthermore, each of the claw head assemblies includes a claw head and a positioning rod. The multiple claw heads are vertically distributed below the multiple openings and are used to hold the bushing to be disassembled. The multiple positioning rods are vertically installed at the multiple openings and can move up and down and be positioned. The positioning rods can move along the direction from one end of the corresponding opening to the other end. The lower ends of the multiple positioning rods are fixedly connected to the upper ends of the multiple claw heads.

[0012] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. It utilizes multiple positioning rods and multiple openings to adjust the position of multiple claws in the vertical and horizontal directions, making adjustment convenient.

[0013] Furthermore, the positioning rod is an adjusting screw, the lower end of which is threadedly connected to the upper end of the corresponding claw head; a positioning nut is threadedly fitted onto the upper end of each adjusting screw, and the positioning nut abuts against the upper side of the corresponding opening.

[0014] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The lower ends of multiple adjusting screws are respectively threaded to the upper ends of multiple claws, which facilitates assembly. In addition, the positioning of multiple adjusting screws and multiple claws is achieved by using multiple adjusting screws and multiple positioning nuts in threaded cooperation, which makes the operation simple and saves time and effort.

[0015] Furthermore, the claw head has an arc-shaped plate-like structure.

[0016] The advantages of adopting the above-mentioned further solution are that the structure is simple, the shape of the multiple claws is reasonably designed, and the curvature of the sleeve to be disassembled is matched with that of the sleeve to be disassembled, so as to disassemble the sleeve.

[0017] Furthermore, each of the claw heads has an insert plate fixedly connected to the inner side of its lower end, and the plurality of insert plates are respectively used to insert into the lower end of the bushing to be disassembled.

[0018] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. Multiple claws use multiple insert plates to support the lower end of the bushing to be disassembled, which facilitates faster disassembly of the bushing and improves efficiency.

[0019] Furthermore, both the inner and outer sides of the insert plate have an arc-shaped structure.

[0020] The advantages of adopting the above-mentioned further solution are that the structure is simple, the shape of the multiple insert plates is reasonably designed, which makes it easier to better support the bottom of the bushing to be disassembled, and facilitates the subsequent disassembly of the bushing.

[0021] Furthermore, the thickness of each of the plurality of insert plates is 3-5 mm.

[0022] The advantages of adopting the above-mentioned further solution are that the structure is simple, the thickness of the insert plate is reasonably designed, and it can be adapted to the gap at the bottom of the bushing, ensuring that the insert plate can be inserted into the gap at the lower end of the bushing.

[0023] Furthermore, the center of the crossbeam is provided with a threaded through hole running vertically through it, and the driving component includes a set screw, which is vertically arranged and threadedly connected to the threaded through hole.

[0024] The beneficial effect of adopting the above-mentioned further solution is that during disassembly, the set screw is rotated in a way that can be conceived by those skilled in the art. The set screw moves downward and presses against the top of the electromagnetic brake by means of the threaded connection with the threaded through hole on the crossbeam, thereby causing multiple claws to drive the bushing upward to disassemble the bushing.

[0025] Furthermore, the upper end of the set screw has a nut for engaging with a wrench.

[0026] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. Manual operation can be made easier and more time-saving and labor-saving by using a wrench and nut to turn the set screw. Attached Figure Description
