Description

Technical Field

[0001] This utility model belongs to the technical field of wind turbine generator set disassembly and assembly equipment, specifically relating to a tool for disassembling and assembling water-cooled pipes of wind turbine generator set converter modules. Background Technology

[0002] As the main system of the wind turbine, the converter system of the wind turbine generates a lot of heat when the wind turbine is running and it performs a series of rectification, inversion, filtering and braking operations. In order to prevent local overheating and equipment damage, a water cooling system is installed on the wind turbine. The cooling water in the water cooling system is transferred to each piece of equipment through cooling water pipes. If any equipment is damaged in the system, the cooling water pipes must be disassembled before the equipment can be removed for repair.

[0003] However, due to the large number and congestion of equipment inside the converter cabinet, and the large thickness of the cooling water pipes, the torque of the wrench is small when disassembling the water pipe heads, making it difficult. Furthermore, since it is a continuous process, a ratchet wrench cannot be used, and only an open-end wrench can be used for disassembly and assembly. However, due to the small torque, after each small torque turn, the wrench must be re-clamped, making the operation very cumbersome. Therefore, there is room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for disassembling and assembling water-cooled pipes of wind turbine converter modules, so as to solve the problem mentioned in the background art that conventional wrenches are inconvenient to operate when disassembling cooling water pipes inside the converter cabinet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool for disassembling and assembling water-cooled pipes of a wind turbine converter module, including a wrench head with an opening at the top for inserting bolts onto the cooling water pipe. Symmetrical placement grooves are provided on the inner wall of the wrench head. A clamping assembly is disposed within the placement grooves, comprising a clamping member and an adjusting member. The clamping member is movably disposed within the placement groove, with a portion protruding outside the groove. The clamping members on both sides move in opposite directions within the placement groove. Thus, when clamping a nut, it can be tightened clockwise and moved counterclockwise. The adjusting member is disposed between the clamping member and the placement groove, adjusting the position of the clamping member within the placement groove to limit the nut on the cooling water pipe.

[0006] Preferably, the clamping member includes a first movable clamping block and a second movable clamping block. The first movable clamping block and the second movable clamping block protrude out of the outer area of ​​the placement groove and are inclined relative to each other. The inclined surfaces of the first movable clamping block and the second movable clamping block are provided with toothed grooves, which can limit and clamp the nut.

[0007] Preferably, the adjusting component includes a spring disposed between the bottom of the first movable clamping block and the placement groove, and between the top of the second movable clamping block and the placement groove. When the nut is engaged and rotated clockwise, the first movable clamping block and the second movable clamping block will limit it. When rotated counterclockwise, the first movable clamping block moves toward the bottom of the placement groove and compresses the spring, while the second movable clamping block moves toward the top of the placement groove, thus compressing the spring to achieve movable disassembly.

[0008] Preferably, both movable clamping blocks 1 and 2 have sliding grooves in the areas inside the placement slot. A limiting pin is provided through the surface of the wrench head, passing through the sliding groove. The end of the limiting pin is outside the wrench head, and a retaining spring is also sleeved on the end of the limiting pin to limit the limiting pin and prevent it from falling off. In use, the limiting pin can limit movable clamping block 1, while movable clamping blocks 1 and 2 can be guaranteed to move in the placement slot without falling off.

[0009] Preferably, the bottom of the wrench head is connected to a handle portion, and a hanging hole is provided at the bottom end of the handle portion, which is not shown in the figure and is used for hanging when not in use.

[0010] Preferably, the top end of the handle portion has a connecting groove, and the bottom end of the wrench head has a protrusion that is movably inserted into the connecting groove. A connector passes through the connection between the handle portion and the protrusion, and the handle portion and / or the wrench head rotate around the connector to adjust the angle of the entire tool according to the actual operating conditions.

[0011] Preferably, the connector includes a through-connecting groove and a protruding bolt, with a locking nut screwed onto the end of the bolt. The locking nut is inserted inside the handle portion to prevent protrusion from affecting normal operation. When adjusting the angle, the angle of the wrench head and the handle portion can be adjusted by tightening the locking nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Through the design of this utility model, when disassembling the cooling water pipe, the movable clamping blocks 1 and 2 cannot move when the nut is rotated clockwise, thus achieving a fixing and fastening effect; while when rotating counterclockwise, the movable clamping blocks 1 and 2 are in a movable state. Therefore, when rotating counterclockwise, the movement of the movable clamping blocks 1 and 2 allows the tool to move to the next fixed point for the next clockwise tightening, making pipe disassembly more convenient and overcoming the shortcomings of the existing structure in use.
