Description

Technical Field

[0001] The utility model relates to the technical field of engineering tools, in particular to a wind turbine coupling disassembly tool. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. To ensure safe and stable operation, regular inspection and maintenance of various components are necessary. For example, the coupling, after long-term use, fits tightly against the shaft. If rust forms between the coupling and the shaft, the two can become stuck, preventing the coupling from being removed promptly.

[0003] To this end, a Chinese patent (application number 202323197304.5) discloses "a wind turbine coupling disassembly tool". The tool rotates a screw so that the screw pushes out the rotating rod connected to the coupling during the descent process, or pulls out the coupling, thereby achieving the disassembly of the coupling. However, the tool needs to keep rotating the screw during use, which takes a long time and is more troublesome. Utility Model Content

[0004] The purpose of the utility model is to provide a wind turbine coupling disassembly tool to solve the problem in the above background technology that the current disassembly tool disassembles the coupling by rotating a screw rod, which takes a long time and is troublesome.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind turbine coupling disassembly tool, comprising: a main board, and also comprising: a handle assembly rotatably installed on one end of the main board, lateral grooves are provided on the outer walls on both sides of the main board, and the same positioning assembly is slidably connected to the inner walls of the two lateral grooves, a traction rod is provided between the positioning assembly and the handle assembly, and one end of the traction rod is rotatably connected to the positioning assembly, and the other end of the traction rod is rotatably connected to the handle assembly, and a groove is provided on the top outer wall of the main board, a T-plate is fixed to the outer wall on one side of the main board, and a limiting assembly is installed on the top outer wall of the main board, and a support assembly is slidably connected in the groove.

[0006] The handle assembly includes a rotating frame, a gripping rod installed at the bottom of the rotating frame, and a rubber sleeve fixed on the outer wall of the gripping rod.

[0007] The clamping assembly comprises a sliding frame, a connecting plate connected to the outer wall of the bottom of the sliding frame, and a clamping ring fixed to the bottom of the connecting plate.

[0008] The support assembly includes a support plate, a T-slot opened on the bottom outer wall of the support plate, an oblique rack installed on the top outer wall of the support plate, a pressing plate fixed to one end of the oblique rack and an anti-slip pad bonded to the outer wall of one side of the pressing plate.

[0009] The limiting component comprises a carrying rod, a sponge sleeve sleeved on the outer wall of the carrying rod and a limiting plate rotatably mounted on one end of the outer wall of the bottom of the carrying rod.

[0010] The top of the T-plate is placed in the T-slot.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model provides a wind turbine coupling disassembly tool, which can clamp the bottom of the clamping assembly on the coupling, and then slide the supporting assembly so that one end of the supporting assembly is against the device casing, thereby supporting the tool and facilitating the worker to use leverage. After one end of the supporting assembly is against the device casing, the limiting assembly can automatically limit the supporting assembly and fix its position. At this time, the worker can hold the bottom of the handle assembly and pull the handle assembly backward. The handle assembly pulls the clamping assembly through the traction rod to move horizontally, and the coupling can be directly pushed off the rotating shaft through the clamping assembly, which is more convenient and quick.
