Specific implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0029] A portable tooling for replacing the motor of a wind turbine generator set includes a vertical column 1. A guiding component is provided at the upper end of the vertical column 1. A steel wire rope 6 is wound around the guiding component. The lower end of the steel wire rope 6 is arranged on one side of the vertical column 1 through a winding wheel 9. A mounting base 14 is fixedly installed at the lower end of the vertical column 1. The mounting base 14 is internally provided with:

[0030] A fixed support 3, the fixed support 3 is a straight rectangular column and is fixedly installed on one side of the mounting base 14 close to the winding wheel 9;

[0031] Two rotating supports 2 are provided. One end of each rotating support 2 is rotatably connected inside the mounting base 14. The two rotating supports 2 are symmetrically arranged, and an adjusting component is provided at the connection between the two rotating supports 2 and the mounting base 14. The adjusting component can adjust the included angle between the two rotating supports 2 and can lock the positions of the rotating supports 2;

[0032] A positioning component, the positioning component is composed of two positioning units. The positioning units are slidably connected to the surface of the rotating support 2. The two positioning units can approach a heavy object suspended on the steel wire rope 6 and clamp it between the two positioning units.

[0033] In the present invention, a heavy object can be easily placed in the air through the steel wire rope 6 and the guiding assembly. By rotating the winding wheel 9, the height of the heavy object can be adjusted, and the heavy object can be accurately and efficiently transported to the replacement position. Moreover, by rotating the rotating support 2 and the fixed support 3 as the bottom support structure of the device, the angle between the rotating supports 2 can be adjusted, which can be adjusted according to the size of the heavy object, making the gravity distribution at the bottom of the column 1 more uniform, increasing the stability of the column 1 itself during the transportation of the heavy object. At the same time, the positioning units on the rotating support 2 can approach the edge of the heavy object from both sides, and the limiting effect of the positioning assembly reduces the shaking of the heavy object during the movement along with the column 1, increasing the stability of the heavy object itself during the transportation process. This tooling is also applicable when handling heavy objects of wind turbines in the warehouse and loading them onto vehicles. This tooling can greatly save manpower and can handle them safely and quickly. In practical applications, when replacing heavy spare parts such as the generator cooling fan motor and the gearbox oil pump motor, from the warehouse to loading onto the vehicle and then to the installation position at the machine position, it can save time and effort, reduce the process of manual handling, and increase safety.

[0034] Among them, the guiding assembly includes an upper connecting column 4. The upper connecting column 4 is fixedly installed at the upper end of the column 1. Pulley 13 is rotatably installed at both the upper and lower ends of the upper connecting column 4. One end of the steel wire rope 6 is fixedly installed on the winding wheel 9, and the other end is a free end on which a hook 5 is fixedly installed. The free end of the steel wire rope 6 is sequentially wound around two groups of pulleys 13 and is suspended below the upper end of the upper connecting column 4. In the present invention, the steel wire rope 6 is limited by the pulley 13. When the winding wheel 9 rotates to wind the steel wire rope 6, the steel wire rope 6 is wound around the winding wheel 9 through the pulley 13, and at this time, the free end of the steel wire rope 6 moves upward.

[0035] Among them, the winding wheel 9 is rotatably installed in the connecting frame 8. The connecting frame 8 is fixedly installed on one side of the column 1. A handle 7 is rotatably installed on one side of the connecting frame 8. The handle 7 is fixedly connected to the winding wheel 9. A plurality of groups of clamping grooves 23 are circumferentially distributed on the handle 7. A sliding groove 21 is opened on one side of the connecting frame 8. A limiting block 22 is slidably connected in the sliding groove 21, and the limiting block 22 can be embedded into the clamping groove 23. In the present invention, the user drives the winding wheel 9 to rotate through the handle 7, controls the lifting of the hook 5 at the free end of the steel wire rope 6. After the adjustment is completed, the limiting block 22 is slid close to the handle 7 through the sliding groove 21, so that the limiting block 22 is clamped into the clamping groove 23 of the handle 7, thereby locking the winding wheel 9 to prevent the reverse rotation and the rapid descent of the hook 5.

[0036] Among them, self-locking universal wheels 12 are fixedly installed on the lower surfaces of the ends of the rotating support 2 and the fixed support 3 away from the installation base 14. An internal threaded rod 20 is rotatably installed in the rotating support 2. The lower end of the positioning unit is threadedly connected to the internal threaded rod 20. The column 1 can be driven to move at high speed through the self-locking universal wheels 12.

[0037] Among them, the positioning unit includes a telescopic rod 10. The upper end of the telescopic rod 10 is rotatably installed with a limiting member 11. The limiting member 11 is composed of two groups of straight plates perpendicular to each other. The lower end of the telescopic rod 10 is threadedly connected to the inner threaded rod 20. The telescopic rod 10 is composed of a sleeve and an inner round rod, and the inner round rod is threadedly connected inside the sleeve. In the present invention, by rotating the inner threaded rod 20, the position of the telescopic rod 10 on the rotating support 2 can be adjusted, so as to adjust the distance between the limiting member 11 and the heavy object. When the limiting member 11 approaches the heavy object suspended on the hook 5, the heavy object can be made to be between the right-angle angles by rotating the limiting member 11. A positioning nut is provided at the rotational connection between the limiting member 11 and the telescopic rod 10.

[0038] Among them, the adjusting assembly includes an intermediate gear 31, a lower mounting bracket 16 and a side gear 15. The side gear 15 is fixedly installed on the rotating support 2. The intermediate gear 31 is rotatably connected to the mounting base 14 and is located between the two side gears 15. The intermediate gear 31 meshes with the side gear 15. In the present invention, when it is necessary to adjust the angle of the rotating support 2, the intermediate gear 31 is rotated to drive the side gear 15 to rotate. The side gear 15 rotates to drive the rotating support 2 and the mounting base 14 to rotate, and the two rotating supports 2 rotate in opposite directions with the same rotation angle magnitude. The rotating supports 2 can be symmetrically distributed on both sides of the column 1 to ensure the stability of the bottom support of the device.

[0039] Among them, the lower mounting bracket 16 is fixedly installed on the mounting base 14. A locking member 17 is fixedly installed on the mounting base 14. A driven disk 24 is rotatably installed inside the locking member 17. The driven disk 24 is fixedly connected to the intermediate gear 31. A rotating motor 19 is fixedly installed on the lower mounting bracket 16. The output end of the rotating motor 19 is fixedly installed with a driving disk 18. The driving disk 18 and the driven disk 24 are coaxially arranged. In the present invention, the driving disk 18 is rotated by the rotating motor 19. The rotation of the driving disk 18 can drive the driven disk 24 inside the locking member 17 to rotate. The rotation of the driven disk 24 drives the intermediate gear 31 to rotate. When the driving disk 18 stops rotating, the locking member 17 automatically locks the position of the driven disk 24, thereby locking the intermediate gear 31. The rotation of the side gear 15 is restricted by the intermediate gear 31, thereby locking the position of the rotating support 2.

[0040] Among them, an intermediate column 25 is fixedly installed in the middle position of the driven disk 24, and spring rods 28 are symmetrically connected on both sides of the intermediate column 25. A movable part 27 is fixedly installed on the end of the spring rod 28 away from the intermediate column 25, and a clamping tooth 29 is fixedly installed on the movable part 27. A ratchet 30 is arranged on the inner side of the locking part 17. The ratchet 30 is arranged in two layers, upper and lower, and in opposite directions. The clamping teeth 29 are respectively engaged with the ratchet 30. Limiting plates are arranged on both sides of the driven disk 24 corresponding to the movable part 27, and the movable part 27 is arranged with an embedding groove. A toggle rod 26 is fixedly installed on the active disk 18, and one end of the toggle rod 26 is embedded in the embedding groove. In the present invention, the active disk 18 rotates to drive the toggle rod 26 to rotate, and the toggle rod 26 rotates to squeeze the side wall of the embedded groove, so that the movable member 27 squeezes the spring rod 28, so that the movable member 27 slides toward the middle column 25, and then the engaging teeth 29 on the movable member 27 are disengaged from the ratchet teeth 30 in the locking member 17, so that the rotation of the toggle rod 26 can drive the driven disk 24 to rotate. When the active disk 18 stops rotating, the squeezing effect of the toggle rod 26 on the embedded groove disappears, and the engaging teeth 29 are automatically engaged with the ratchet teeth under the action of the spring rod 28, thereby limiting the rotation of the driven disk 24, and then limiting the rotation of the intermediate gear 31.
