Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine disassembly and assembly tools, and in particular to a quick disassembly and assembly tool for wind turbines. Background Technology

[0002] When conducting tests on wind turbines, wrenches are typically used to unscrew the bolts and nuts. Existing wrench-based tools, designed to accommodate different sizes of bolts and nuts, feature wrench heads that are removable from the handle. However, due to the influence of the retaining arm on the connecting column, the wrench head must be gripped before pulling it out. Since the wrench head frequently extends into the equipment to rotate the bolts and nuts, it often accumulates lubricating oil. This necessitates wiping the wrench head before quick removal, as it easily slips, making the operation cumbersome and significantly impacting the efficiency of wind turbine assembly and disassembly.

[0003] Based on the above background, a quick assembly and disassembly tool for wind turbines is proposed to solve the problem. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a quick assembly and disassembly tool for wind turbines.

[0006] To achieve the above objectives, the technical solution of this utility model is: a quick assembly and disassembly tool for wind turbines, comprising: a handle, a connecting post, a wrench head, a slot, a plug rod, and a stop arm. The handle is equipped with a plug rod, and two stop arms are connected to the handle and located on both sides of the plug rod. A connecting post is installed on the lower side of the wrench head, and a slot for inserting the plug rod is provided on the connecting post. The handle has an adjustment groove and a sliding groove. The adjustment groove is connected to one side of the sliding groove. A spring is installed in the adjustment groove, and a lifting rod is installed below the spring. A top rod is inserted into the sliding groove. One side of the lifting rod passes through the adjustment groove and connects to the top rod, with the upper end of the top rod abutting against the lower side of the connecting post.

[0007] Preferably, the adjustment groove is located on the side wall of the handle.

[0008] Preferably, a sealing ring is installed on the inner wall of the slot.

[0009] Preferably, the inner ring of the sealing ring fits against the outer wall of the insert.

[0010] As a preferred option, the wrench head has anti-slip grooves on the wrench mouth.

[0011] Preferably, the slot and the insert are triangular or hexagonal in shape.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: By pulling the lifting rod upward, the lifting rod moves upward in the adjusting groove, while simultaneously compressing the spring to deform. The lifting rod drives the top rod to move upward in the sliding groove until the upper side of the top rod moves out of the sliding groove. At the same time as it moves out, it pushes the connecting column upward, causing the connecting column to move upward until it is no longer obstructed by the stop arm. Personnel can then remove the wrench head through the connecting column. This process does not require contact with the wrench head to remove it from the insertion rod, making the disassembly and replacement of the wrench head more convenient. The wrench head can be replaced quickly, which means the disassembly and assembly of the wind turbine can also be quick, thereby improving the efficiency of disassembly and assembly of the wind turbine.

[0013] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

It should be noted that, provided there is no conflict, the various embodiments and features within them can be combined with each other, and all resulting technical solutions are within the protection scope of this utility model.

[0025] Furthermore, numerous specific details are set forth in the following description for illustrative purposes to provide a thorough understanding of the embodiments of this invention. However, it will be apparent to those skilled in the art that this invention may be practiced without the specific details or particular methods described herein.

[0026] Please see Figure 1-4 This utility model provides a quick assembly and disassembly tool for wind turbines, including: a handle 1, a connecting post 2, a wrench head 3, a slot 4, a plug rod 5, and a stop arm 6. The plug rod 5 is installed on the handle 1, and two stop arms 6 are connected to the handle 1 and located on both sides of the plug rod 5. The connecting post 2 is installed on the lower side of the wrench head 3, and the slot 4 for inserting the plug rod 5 is opened on the connecting post 2. The handle 1 has an adjustment groove 11 and a sliding groove 12. The adjustment groove 11 is connected to one side of the sliding groove 12. A spring 13 is installed in the adjustment groove 11, and a lifting rod 14 is installed on the lower side of the spring 13. A top rod 15 is inserted into the sliding groove 12. One side of the lifting rod 14 passes through the adjustment groove 11 and is connected to the top rod 15. The upper end of the top rod 15 abuts against the lower side of the connecting post 2.

[0027] When in use, the connecting post 2 is inserted into the slot 4 of the plug rod 5. Under the blocking action of the stop arm 6, the connecting post 2 will not rotate on the handle 1, so that the wrench head 3 is fixed on the handle 1. The wrench head 3 can then be used to turn the bolts and nuts on the wind turbine. When the wrench head 3 needs to be replaced, the lifting rod 14 is pulled upward. The lifting rod 14 moves upward in the adjusting groove 11, and at the same time, the spring 13 is compressed and deformed. The lifting rod 14 drives the top rod 15 to move upward in the slide groove 12 until the upper side of the top rod 15 moves out of the slide groove 12. As it moves out, it pushes the connecting post 2 upward, so that the connecting post 2 moves upward. When it moves up and is no longer blocked by the stop arm 6, the personnel can remove the wrench head 3 through the connecting post 2, so as to quickly replace it with the corresponding wrench head 3 and assemble it on the handle 1.

[0028] According to some embodiments of this application, optionally, the adjustment groove 11 is located on the side wall of the handle 1. The handle 1 has a pull rod 14 that can be moved within the adjustment groove 11 from the outside of the handle 1.

[0029] According to some embodiments of this application, optionally, a sealing ring 7 is installed on the inner wall of the slot 4, and the inner ring of the sealing ring 7 fits against the outer wall of the insertion rod 5. This increases the tightness between the slot 4 and the insertion rod 5, making the connecting post 2 more stable on the insertion rod 5.

[0030] According to some embodiments of this application, optionally, the wrench head 3 has anti-slip grooves 8 installed on the wrench opening. Having the wrench head 3 increases the friction between the bolt and nut when rotating, thereby preventing slippage and making rotation smoother.

[0031] According to some embodiments of this application, optionally, the slot 4 and the insertion rod 5 adopt a triangular or hexagonal structure, which provides a better locking effect.
