Detailed Implementation

[0026] Please see Figures 1-8The present utility model provides a horizontal rotor hoisting device, comprising a rotating shaft hoisting frame A200. A rotating shaft hoisting frame B300 is installed on one side of the rotating shaft hoisting frame A200, and a winding iron core clamping mechanism 400 is arranged thereon. The rotating shaft hoisting frame A200 is provided with a hoisting beam 23, and an adjusting channel 25 is opened inside the hoisting beam 23. An adjusting arm 32 is inserted into the adjusting channel 25, and a hoisting arm B31 is fixed at the end of the adjusting arm 32. The bottoms of both the hoisting arm B31 and the hoisting arm A21 are provided with fixing cylinders 22, a rotor rotating shaft 100 is inserted into the fixing cylinders 22, and a rotor winding iron core 101 is fixed on the rotor rotating shaft 100.

[0027] As a preferred embodiment, both the hoisting arm B31 and the hoisting arm A21 are L-shaped, the fixing cylinders 22 at the bottoms of the hoisting arm B31 and the hoisting arm A21 are arranged horizontally, and a rubber pad is arranged inside the fixing cylinder 22.

[0028] A plurality of sets of clamping grooves 24 are opened at the bottom of the hoisting beam 23, the distance between every two adjacent sets of clamping grooves 24 is consistent, the upper side inside the clamping groove 24 is circular, and a folding boom crane hanger 26 is mounted on the hoisting beam 23.

[0029] The top of the folding boom crane hanger 26 is provided with a hoisting ring, the folding boom crane hanger 26 is in a square shape, a plurality of sets of clamping posts 261 are fixed inside the folding boom crane hanger 26, and the plurality of sets of clamping posts 261 are all clamped inside the clamping grooves 24.

[0030] Working principle: A shaft lifting frame B300 is installed on one side of the shaft lifting frame A200, and a winding core clamping mechanism 400 is provided on the shaft lifting frame A200 to clamp the rotor winding core 101. The lifting beam 23 is set on the shaft lifting frame A200, and an adjustment channel 25 is opened inside it. An adjustment arm 32 is inserted inside the adjustment channel 25, and a lifting arm B31 is fixed to the end of the adjustment arm 32. By adjusting the position of the adjustment arm 32 in the adjustment channel 25, the distance between the lifting arm B31 and the lifting arm A21 can be adjusted to accommodate rotor shafts 100 of different lengths. Both the lifting arm B31 and the lifting arm A21 are "L" shaped, and a horizontally set fixing cylinder 22 is provided at the bottom. The rotor shaft 100 is inserted inside the fixing cylinder 22, and a rubber pad is provided inside the fixing cylinder 22 to buffer and fix the rotor shaft 100 to prevent slippage and damage. The bottom of the lifting beam 23 has multiple sets of slots 24. The upper side of the inside of the slots 24 is circular. The folding arm crane suspension component 26 is engaged in the slots 24 by multiple sets of locking pins 261 fixed inside. The top of the folding arm crane suspension component 26 is provided with a lifting ring for connecting external lifting equipment, i.e., the folding arm crane. When lifting, the rotor shaft 100 is fixed in the fixed cylinder 22 by the folding arm crane. The winding core clamping mechanism 400 ensures the stability of the rotor winding core 101. The locking position of the locking pins 261 of the folding arm crane suspension component 26 in the slots 24 is adjustable to achieve flexible adjustment of the lifting point, thereby ensuring that the rotor remains horizontal during the lifting process and avoiding tilting or shaking.

[0031] The adjustable lifting arm A21 and fixed cylinder 22 can accommodate rotor shafts 100 of different sizes, improving the versatility and flexibility of the equipment. The rubber pads effectively protect the surface of the rotor shaft 100 from scratches and wear, extending the life of the components. The slot 24 and locking post 261 structure allows for quick adjustment of the lifting point position, ensuring lifting balance and stability. The horizontal lifting method reduces stress concentration and potential damage to the rotor during the lifting process, improving operational safety and lifting efficiency. The overall structure is simple and reliable, suitable for various industrial lifting scenarios.

[0032] In a preferred embodiment, both the shaft hoisting frame A200 and the shaft hoisting frame B300 are equipped with a winding core clamping mechanism 400, and both the shaft hoisting frame A200 and the shaft hoisting frame B300 clamp and fix the rotor winding core 101 through the winding core clamping mechanism 400.

[0033] The winding core clamping mechanism 400 includes clamping arm A43 and clamping arm B44, and both clamping arm A43 and clamping arm B44 are provided with lifting handles 431 at the bottom. The lifting handles 431 are "C" shaped and wrapped around the outer circumference of the rotor winding core 101. The end of the lifting handles 431 is provided with a clamping block 432.

[0034] A connecting shaft 42 is inserted between clamping arms A43 and clamping arms B44, and a fixed seat 41 is provided at the end of the connecting shaft 42. The fixed seat 41 is connected to the lifting arm A21. A second transmission arm 46 is rotatably connected to clamping arm A43, and a first transmission arm 45 is rotatably connected to clamping arm B44.

[0035] The second transmission arm 46 and the first transmission arm 45 are V-shaped, and their upper parts are movably connected by a pin. A drive seat 47 is provided on the pin at the end of the second transmission arm 46 and the first transmission arm 45. A drive cylinder 48 is provided on the drive seat 47, and the drive cylinder 48 is fixed on the lifting beam 23. The output end of the drive cylinder 48 is fixedly connected to the drive seat 47. The drive cylinder 48 drives the clamping arms A43 and B44 to unfold and converge through the first transmission arm 45, the second transmission arm 46 and the drive seat 47.

[0036] The winding core clamping mechanism 400 operates as follows: The drive cylinder 48 is activated, its output end pushes or pulls the drive seat 47. The drive seat 47 drives the first transmission arm 45 and the second transmission arm 46 connected to it to move. Since the first transmission arm 45 and the second transmission arm 46 are V-shaped and their upper parts are movably connected by a pin, they form a linkage mechanism similar to scissors, converting the linear motion of the drive cylinder 48 into the motion of the clamping arms A43 and B44 around the connecting shaft 42. When the drive cylinder 48 pushes the drive seat 47, the first transmission arm 45 and the second transmission arm 46 will spread apart, thereby driving the clamping arms A43 and B44 to overcome the constraint of the connecting shaft 42 and swing away from each other, achieving a converging action. This causes the two C-shaped lifting handles 431 installed at the bottom of the clamping arms to tightly wrap around and clamp the outer circumference of the rotor winding core 101. At the same time, the clamping blocks 432 at the ends of the lifting handles 431 further tighten to enhance the fixation. Conversely, when the drive cylinder 48 pulls the drive seat 47, it causes the clamping arms A43 and B44 to unfold, releasing the clamping of the rotor winding core 101. This process is carried out simultaneously on the shaft hoisting frame A200 and the shaft hoisting frame B300, achieving stable horizontal hoisting and fixing of both ends of the rotor winding core 101.

[0037] The clamping is mechanized and automated through the drive cylinder 48 and linkage mechanism, making operation labor-saving and accurate. Two "C"-shaped lifting arms 431 wrap around the iron core from both sides, and combined with the design of the clamping block 432, they provide uniform and powerful clamping force, effectively preventing the rotor from shaking, rotating or slipping during the lifting process, ensuring the stability and safety of the lifting. This design is applicable to rotor winding iron cores 101 of different diameters, with strong versatility, which greatly improves the efficiency and reliability of the lifting operation.

[0038] The rotor shaft 100 is horizontally supported and fixed at both ends by the fixing cylinder 22 at the bottom of the shaft lifting frame A200 and shaft lifting frame B300, ensuring a symmetrical distribution of the stress points and effectively preventing deformation of the rotor shaft 100 due to uneven stress at both ends. Simultaneously, the winding core clamping mechanism 400 installed on both shaft lifting frames A200 and B300 tightly wraps around and clamps the outer circumference of the rotor winding core 101 from both sides through its "C"-shaped lifting handle 431 and clamping block 432, forming a support for the rotor shaft 100 together with the fixing cylinder 22. The coordinated fixation of the rotor winding core 101 evenly distributes the massive rotor weight across the two lifting frames, greatly improving the rotor's gravity distribution and preventing tilting or swaying caused by an unstable center of gravity. In addition, the lifting beam 23, adjustable adjusting arm 32, and folding arm suspension 26 allow adjustment of the balance point of the entire lifting system, ensuring that the rotor remains horizontal during lifting. This fundamentally solves the key safety problem of the rotor easily falling or the shaft deforming when lifted into the air due to its large weight and uneven gravity distribution, significantly improving the stability and reliability of the lifting operation.
