Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary tooling, in particular to an auxiliary tooling for disassembling and assembling a motor of a mobile wind turbine generator set. Background Art

[0002] Wind turbines are power generation systems that convert wind energy into electrical energy and are an important component of the renewable energy sector. Wind power drives the blades to rotate, which is transmitted to the gearbox through the hub and main shaft. The gearbox increases the speed and drives the generator to rotate, generating electricity. The electricity generated by the generator is converted into alternating current that meets the requirements of the power grid through an inverter, and then boosted by a transformer and fed into the power grid.

[0003] After searching, the Chinese patent with publication number CN119191113A discloses an auxiliary tool for disassembling and assembling a motor of a mobile wind turbine, comprising a support component, including a support assembly, an adjustment assembly arranged on the support assembly, and a moving assembly arranged on the support assembly; a control component, including a drive assembly arranged on the support assembly, a lifting assembly arranged on the support assembly, and a transmission assembly arranged on the drive assembly. By controlling the operation of the drive motor, the worm drives the worm wheel to rotate, thereby rotating one of the second threaded rods, and then the two second threaded rods rotate together through the cooperation of the sprocket and the chain, and the lifting block is controlled to move up and down, so that the connecting hook on the lifting block approaches the motor that needs to be disassembled and repaired. After the connection is completed, the lifting block is controlled to move upward, and the limiting assembly clamps the motor to prevent shaking. However, the above solution still has the following shortcomings when used in practice: In the above-mentioned device operation scenario, when the motor needs to be safely and stably lifted from the equipment by means of a connecting hook, the conventional operation method is usually to arrange multiple cables at a reasonable position outside the motor, and then reliably connect the free ends of the cables to the connecting hooks to form a stable lifting system. However, this traditional operation method has many disadvantages: on the one hand, the cables are in direct contact with the outer wall of the motor. During the process of lifting, moving or placing the motor, due to the large weight of the motor itself, friction will inevitably be generated between the cables and the outer wall of the motor. This friction is very likely to cause scratches on the outer wall of the motor, thereby affecting the appearance integrity of the motor; on the other hand, the cable laying process is relatively cumbersome, and the staff need to spend a lot of time and energy to ensure that the cables are accurately arranged on the outer wall of the motor and the force is evenly distributed. In addition, the staff need to repeatedly check the firmness of the connection between the cables and the connecting hooks, which increases the operation time cost and reduces work efficiency.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 2 、 Figure 3 As shown, an auxiliary tool for disassembling and assembling a motor of a mobile wind turbine generator set includes a lifting unit and a stabilizing unit; The lifting unit includes a mobile frame 11, a cantilever 12 is provided on the top surface of the mobile frame 11, a winch 13 is slidably mounted on the outer wall of the cantilever 12, and a main hook 14 is provided on the lifting end of the winch 13; The stabilizing unit includes a bottom plate 21 fixedly mounted on the bottom surface of the winch 13. Stabilizing sleeves 22 are provided at the four corners of the bottom plate 21. Stabilizing rods 23 are provided on the inner walls of the four stabilizing sleeves 22. Slide plates 24 are slidably mounted on the inner walls of the stabilizing sleeves 22. The top surface of the stabilizing rods 23 is fixedly connected to the bottom surface of the slide plates 24. A connection structure is provided between the top of the stabilizing sleeve 22 and the bottom plate 21. The connection structure includes three arc-shaped openings 25 distributed at equal intervals on the top surface of the bottom plate 21. The three arc-shaped openings 25 are connected by a connecting opening 26. A sliding rod 27 corresponding to the arc-shaped openings 25 and the connecting opening 26 is fixedly installed on the top surface of the stabilizing sleeve 22. A clamping block 28 is fixedly installed on the top surface of the sliding rod 27. The cross-sectional shape of the clamping block 28 is set to be trapezoidal. First, the staff can push the entire device through the mobile frame 11 to move it to the position of the motor to be disassembled and assembled in the wind turbine set, and then the cantilever 12 can be swung to adjust the angle so that the winch 13 can correspond to the motor. After the preparation is completed, the bottom plate 21 can be located just above the motor. The staff can adjust the position of the four stabilizing sleeves 22 in turn according to the position of the two cross braces at the bottom of the motor. When adjusting, the stabilizing sleeve 22 can be pushed upward to separate the block 28 from the arc-shaped opening 25 and the connecting opening 26, and then the stabilizing sleeve 22 can be pushed upward to separate the block 28 from the arc-shaped opening 25 and the connecting opening 26. The movement of the sleeve 22 causes the slide bar 27 to move along the arc-shaped opening 25, and the slide bar 27 can enter the arc-shaped opening 25 at different positions through the connecting opening 26, so as to ensure the adjustment range of the stabilizing sleeve 22, so that the stabilizing rod 23 can correspond to the end of the cross stretcher. After the adjustment is completed, the stabilizing sleeve 22 can be loosened. At this time, under the action of gravity, the blocking block 28 can enter the arc-shaped opening 25 and use the two inclined surfaces of the trapezoid to engage with the inner wall of the arc-shaped opening 25. The greater the gravity, the tighter the blocking block 28 is engaged, ensuring stability during the lifting process.

[0022] like Figure 6 、 Figure 8 As shown, the bottom end of the stabilizing rod 23 is provided with a clamping structure, which includes a guide frame 31 provided at the bottom end of the stabilizing rod 23. Two guide blocks 32 are slidably mounted on the inner wall of the guide frame 31. A connecting frame 33 is fixedly mounted on the bottom end of the stabilizing rod 23. Two pull plates 34 are symmetrically hinged to the inner wall of the connecting frame 33. The bottom ends of the two pull plates 34 are respectively hinged to the top surfaces of the two guide blocks 32. The bottom surfaces of the two guide blocks 32 are fixedly mounted with clamping plates 35. When the two guide blocks 32 slide, the cross stretcher 31 can be clamped by the clamping plates 35 when the motor is lifted, and the clamping plates 35 can firmly clamp the cross stretcher for stable lifting. When the motor is lowered, the connecting frame 33 moves downward, which can cause the two guide blocks 32 to move away from each other, so that the clamping plates 35 are separated from the cross stretcher and detached from the motor.

[0023] like Figure 6 、 Figure 9 As shown, a hoisting structure is provided at the bottom end of the stabilizing rod 23, which includes a winding box 41 fixedly mounted on the outer wall of the bottom end of the stabilizing rod 23, a shaft 42 is rotatably mounted on the inner wall of the winding box 41, a winding disc 43 is fixedly sleeved on the outer wall of the shaft 42, a torsion spring 44 is sleeved on the end of the shaft 42, and the two ends of the torsion spring 44 are respectively fixedly connected to the shaft 42 and the winding box 41, a cable 45 is provided on the inner side of the winding disc 43, the movable end of the cable 45 passes through the outer wall of the winding box 41 and is fixedly mounted with an auxiliary hook 46 corresponding to the main hook 14; The staff then pulls the auxiliary hook 46 to drive the winding drum 43 to unwind through the cable 45. After the cable 45 is unwound, the auxiliary hook 46 can be connected to the main hook 14 to complete the connection to the motor. After use, the auxiliary hook 46 can be separated from the main hook 14. At this time, under the action of the torsion spring 44, the shaft 42 and the winding drum 43 can be reversed to rewind the cable 45, avoiding the cable 45 from being scattered and convenient for storage. The staff can start the winch 13 to lift the main hook 14, and when the main hook 14 is lifted, the auxiliary hook 46 connected to it can be lifted synchronously, and when the auxiliary hook 46 is lifted, the stabilizing rod 23 can be pulled by the cable 45, so that the stabilizing rod 23 slides upward along the stabilizing sleeve 22 through the slide plate 24.

[0024] like Figure 4 、 Figure 5 、 Figure 10As shown, a locking assembly is provided between the stabilizing sleeve 22 and the stabilizing rod 23, the locking assembly includes four connecting frames 51 distributed in a ring array and hinged to the bottom end of the stabilizing sleeve 22, the bottom end of the connecting frame 1 51 is hinged with a connecting block 52, the bottom of the connecting block 52 is hinged with a connecting frame 2 53, the bottom end of the connecting frame 2 53 is rotatably mounted with a guide wheel 54, a side of the connecting block 52 is fixedly mounted with a support plate 55, and an end of the support plate 55 away from the connecting block 52 is fixedly mounted with a friction plate 57 adapted to the stabilizing rod 23, the outer wall of the guide wheel 54 and the side of the friction plate 57 are both provided with a number of evenly distributed convex bumps, and a supporting spring 1 56 is fixedly installed between the support plate 55 and the opposite sides of the connecting frame 1 51 and the connecting frame 2 53, the bottom end of the connecting frame 2 53 is fixedly mounted with a fixing box 61, and the end of the rotating shaft is located on the inner side of the fixing box 61, and the inner side of the fixing box 61 is provided with a limiting mechanism corresponding to the rotating shaft; The limiting mechanism includes a rotating disk 62 fixedly mounted on the end of the rotating shaft. The outer wall of the rotating disk 62 is provided with a plurality of slots 63 distributed in an annular array. The inner wall of the slot 63 is slidably mounted with limiting teeth 64. A limiting spring 65 is fixedly mounted between the bottom surface of the limiting teeth 64 and the inner bottom surface of the slot 63. The inner wall of the fixed box 61 is provided with a plurality of limiting teeth and grooves 66 distributed in an annular array. Corresponding magnetic pieces 67 are fixedly mounted on the top surface of the limiting teeth 64 and the inner wall of the limiting teeth and grooves 66. During the normal hoisting of the motor, under the action of the support spring 1 56, the guide wheel 54 at the bottom end of the connecting frame 2 53 can fit with the outer wall of the stabilizing rod 23 and is not in a clamped state. At the same time, under the support of the guide wheel 54, the connecting frame 1 51 and the connecting frame 2 53 are in an inclined state, the support plate 55 is in a horizontal state, the friction plate 57 does not contact the stabilizing rod 23, and the stabilizing rod 23 can drive the guide wheel 54 to rotate when it moves. If the motor falls accidentally during the hoisting process, the stabilizing rod 23 can fall quickly and drive the guide wheel 54 to rotate. Compared with the speed of the stabilizing rod 23 when it moves normally, the rotation speed of the guide wheel 54 increases sharply at this time, and the turntable 62 can be driven to rotate at high speed through the rotating shaft. The turntable 62 rotates at high speed. When the turntable 62 is locked, the guide wheel 54 cannot rotate either. Under the action of the friction force between the guide wheel 54 and the stabilizing rod 23, the stabilizing rod 23 can drive the guide wheel 54 to move downward and drive the connecting frame 1 51 and the connecting frame 2 53, so that the four connecting blocks 52 move toward each other and push the support plate 55 and the friction plate 57, so that the four friction plates 57 are pressed against the outer wall of the stabilizing rod 23, which can play a certain deceleration role under the action of the friction force.

[0025] like Figure 5 、 Figure 7 、 Figure 11 、 Figure 12 As shown, the outer wall of the stabilizing sleeve 22 is provided with a buffer assembly, which includes an oil storage barrel 71 fixedly mounted on the outer wall of the stabilizing sleeve 22. The interior of the oil storage barrel 71 is filled with buffer oil. A push rod 72 is provided on the top surface of the oil storage barrel 71. A push plate 73 is fixedly mounted on the top of the push rod 72. A mounting plate 74 is fixedly mounted on the top of the push rod 72. A second support spring 75 is sleeved on the outer wall of the push rod 72, and the two ends of the second support spring 75 are fixedly connected to the oil storage barrel 71 and the mounting plate 74 respectively. The oil storage barrel 71 and the stabilizing sleeve 22 are connected through a conduit 76. The top surface of the oil storage barrel 71 is provided with a positioning structure. The positioning structure includes a slide groove 77 provided on the top surface of the oil storage barrel 71, a limit plate 78 is slidably installed on the inner wall of the slide groove 77, a positioning groove corresponding to the limit plate 78 is provided on the outer wall of the push rod 72, a bracket 79 is fixedly installed on the top surface of the oil storage barrel 71, a pressure plate 710 is slidably installed on the inner wall of the bracket 79, an inclined plate 711 is hinged on the top surface of the limit plate 78, the top end of the inclined plate 711 is hinged to the bottom surface of the pressure plate 710, and a pull rod 712 is fixedly installed between the end of the pressure plate 710 away from the inclined plate 711 and the side surface of the connecting block 52; When the locking cam 75 is in the unlocking state, the locking cam 710 is locked, and the locking cam 711 is locked, so that the locking cam 710 can be locked.

[0026] The technical solution provided by the present invention is that when in use, the staff can first push the entire device through the mobile frame 11 to move it to the position of the motor to be disassembled and assembled in the wind turbine set, and then the cantilever 12 can be swung to adjust the angle so that the winch 13 can correspond to the motor. After the preparation is completed, the bottom plate 21 can be located directly above the motor. The staff can adjust the positions of the four stabilizing sleeves 22 in turn according to the positions of the two cross braces at the bottom of the motor. During the adjustment, the stabilizing sleeve 22 can be pushed upward to separate the block 28 from the arc-shaped opening 25 and the connecting opening 26. Then the stabilizing sleeve 22 can be moved to make the slide bar 27 move along the arc-shaped opening 25, and the slide bar 27 can enter the arc-shaped opening 25 at different positions through the connecting opening 26, so as to ensure the adjustment range of the stabilizing sleeve 22, so that the stabilizing rod 23 can correspond to the end of the cross stretcher. After the adjustment is completed, the stabilizing sleeve 22 can be loosened. At this time, under the action of gravity, the clamping block 28 can enter the arc-shaped opening 25 and use the two inclined surfaces of the trapezoid to engage with the inner wall of the arc-shaped opening 25. The greater the gravity, the tighter the clamping block 28 is engaged, ensuring stability during the lifting process. After the position adjustment of the stabilizing sleeve 22 is completed, the staff can place the guide frame 31 on the outside of the end of the cross stretcher, and the clamping plates 35 on the bottom surfaces of the two guide blocks 32 are respectively located on both sides of the cross stretcher, and the four guide frames 31 are placed in sequence so that they are located at both ends of the two cross stretchers. Then the staff pulls the auxiliary hook 46 to drive the reel 43 to unwind through the cable 45. After the cable 45 is unwound, the auxiliary hook 46 can be connected to the main hook 14 to complete the connection to the motor. After use, the auxiliary hook 46 can be separated from the main hook 14. At this time, under the action of the torsion spring 44, the shaft 42 and the reel 43 can be reversed to rewind the cable 45, avoiding the cable 45 from being scattered and convenient for storage. When the above preparations are completed, the staff can start the hoisting machine 13 to lift the main hook 14. When the main hook 14 is lifted, the auxiliary hook 46 connected to it can be moved synchronously. When the auxiliary hook 46 is lifted, the stabilizing rod 23 can be pulled by the cable 45, so that the stabilizing rod 23 slides upward along the stabilizing sleeve 22 through the slide plate 24. When the stabilizing rod 23 moves upward, it can pull the connecting frame 33. When the connecting frame 33 moves upward, it can pull the two pulling plates 34. When the two pulling plates 34 are pulled, they can rotate and pull the guide blocks 32. When the two guide blocks 32 are pulled, they can slide along the guide frame 31 in the direction of approaching each other. When the two guide blocks 32 slide, they can clamp the cross stretcher through the clamping plate 35. After the motor is lifted, the clamping plate 35 can firmly clamp the cross stretcher for stable lifting. When the motor is lowered, the connecting frame 33 moves downward, which can make the two guide blocks 32 move in the direction of moving away from each other, so that the clamping plate 35 is separated from the cross stretcher and separated from the motor. In the process of normal hoisting of the motor, under the action of the supporting spring 1 56, the guide wheel 54 at the bottom end of the connecting frame 2 53 can fit with the outer wall of the stabilizing rod 23 and is not in a clamped state. At the same time, under the support of the guide wheel 54, the connecting frame 1 51 and the connecting frame 2 53 are in an inclined state, the support plate 55 is in a horizontal state, the friction plate 57 does not contact the stabilizing rod 23, and the stabilizing rod 23 can drive the guide wheel 54 to rotate when it moves. If the motor falls accidentally during the hoisting process, the stabilizing rod 23 can fall quickly and drive the guide wheel 54 to rotate. Compared with the speed of the stabilizing rod 23 when it moves normally, the rotation speed of the guide wheel 54 increases sharply at this time, and the turntable 62 can be driven to rotate at high speed through the rotating shaft. The turntable 62 rotates at high speed. When the rotating disk 62 is locked, the guide wheel 54 cannot rotate. Under the action of the friction between the guide wheel 54 and the stabilizing rod 23, the stabilizing rod 23 falls and drives the guide wheel 54 to move downward and drive the connecting frame 1 51 and the connecting frame 2 53, so that the four connecting blocks 52 move in the direction of approaching each other and push the support plate 55 and the friction plate 57, so that the four friction plates 57 are pressed against the outer wall of the stabilizing rod 23, which can play a certain deceleration role under the action of the friction force. When the locking cam 710 is in the unlocked position, the locking cam 710 is in the unlocked position, and the locking cam 711 is in the unlocked position, so that the locking cam 710 is locked.
