Description

Technical Field

[0001] This utility model relates to the field of iron core lifting tools, specifically a new type of integrated lifting tool. Background Technology

[0002] The wound core of a transformer is the core component in the entire production process of a wound transformer. During manufacturing, the wound core requires annealing to reorganize magnetic domains. Annealing necessitates placing the core on a dedicated annealing tray for hoisting. Currently, hoisting these trays relies on manual dragging of lifting ropes, requiring workers to hook the ropes onto the tray's lifting lugs. This method is time-consuming, labor-intensive, and inconvenient, and poses a risk of serious safety accidents due to human error. This invention reduces the labor intensity for workers and, by adding a safety interlock switch, ensures absolutely reliable hoisting and guarantees operator safety. Utility Model Content

[0003] The purpose of this utility model is to provide a new type of integrated lifting device, which uses the rotation of the longitudinal synchronous shaft to drive the movement of the nut and the slide rail, so that the rotating shaft moves back and forth along the slide rail while moving left and right, thereby rotating the rotating shaft and the rotary lock to lock the rotary lock onto the special iron core annealing tray.

[0004] This utility model provides the following technical solution: A novel integrated lifting device includes a mounting base frame. Multiple synchronously rotating longitudinal shafts are mounted on the base plate of the mounting base frame via bearing seats. Threads are formed on the ends of the longitudinal synchronous shafts, and nuts are connected to the threads. The nuts move back and forth along the longitudinal synchronous shafts. A slide rail is formed on the lower surface of the nuts, and a rotating shaft is inserted into the slide rail. A rotary lock is connected to the lower end of the rotating shaft. The rotary lock is connected to the mounting base frame via a mounting bracket, and the rotary lock is rotatably connected to the mounting bracket. The mounting bracket is fixed to the bottom surface of the mounting base frame.

[0005] Furthermore, the rotary lock includes a rotating shaft and a paddle. A corresponding through hole or slot is opened in the special iron core annealing tray to insert the rotary lock. The paddle is inserted into the special iron core annealing tray, and the rotation of the paddle limits the bottom of the special iron core annealing tray, thereby locking the special iron core annealing tray.

[0006] Furthermore, the bottom of the mounting frame is also connected to a mounting base, and a guide rod slides up and down inside the mounting base. The guide rod is inserted into the positioning hole of the special iron core annealing tray for guidance and positioning.

[0007] Furthermore, adjacent longitudinal synchronous shafts are connected and rotate together via a steering gear. A transverse synchronous shaft is connected to one side of the steering gear. The transverse synchronous shaft is connected to the output end of the motor and the reducer, and is driven by the motor and the reducer.

[0008] Furthermore, two transverse synchronous shafts are connected to the output ends of the motor and reducer, and a steering gear is connected to the other end of each of the two transverse synchronous shafts. Both sides of each steering gear are connected to a longitudinal synchronous shaft, and the steering gear is used to make the four longitudinal synchronous shafts rotate synchronously.

[0009] Furthermore, a pulley bracket is fixed on the upper surface of the mounting base frame, and a pulley is rotatably connected inside the pulley bracket via a pulley shaft. A steel wire rope is wound on the pulley for lifting and lowering the special iron core annealing tray.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) The rotation of the longitudinal synchronous shaft drives the nut and slide rail to move, so that the rotating shaft moves back and forth along the slide rail while moving left and right, so that the rotating shaft and the rotary lock rotate, thereby locking the rotary lock onto the special iron core annealing tray. (2) The motor drives the reducer to rotate through the output shaft. The reducer then transmits the speed to the transverse and longitudinal synchronous transmission shafts, which in turn drive the rotary lock to rotate, thus achieving synchronous transmission of torque power. All transmission shafts are fixed inside the mounting base frame by bearing seats and are synchronously locked to maintain stability. (3) The guide rod is installed in the mounting base and slides up and down to position and guide the positioning hole of the special iron core annealing tray, reducing the requirements for the positioning accuracy of the crane, making it convenient for operators to operate and improving labor efficiency; (4) A pulley assembly is installed on the upper part of the base frame, and the lifting and lowering of the special iron core annealing tray is controlled by pulling the upper steel wire rope.

[0013] Please see Figure 1 and Figures 4 to 6 This utility model provides a technical solution: a novel integrated lifting device, including a mounting base frame 1. Four synchronously rotating longitudinal shafts 11 are mounted on the upper surface of the base plate of the mounting base frame 1 via bearing seats 10. The longitudinal synchronous shafts 11 are connected in pairs via a steering gear 9 and rotate together. A transverse synchronous shaft 12 is connected to one side of the steering gear 9. The rotation of the transverse synchronous shaft 12 drives the steering gear 9 to rotate, further driving the longitudinal synchronous shafts 11 to rotate. Both transverse synchronous shafts 12 are connected to both sides of a reducer 13, which is driven to rotate by a motor 14. The ends of the longitudinal synchronous shafts 11 are threaded. A nut 15 is threaded onto the threaded part. The nut 15 moves back and forth along the longitudinal synchronous shaft 11 by the rotation of the longitudinal synchronous shaft 11. A slide rail 16 is formed on the lower surface of the nut 15. A rotating shaft 17 is inserted into the slide rail 16. A rotary lock 6 is connected to the lower end of the rotating shaft 17. The rotary lock 6 is connected to the mounting base frame 1 through the mounting support 5. The rotary lock 6 is rotatably connected to the mounting support 5. The mounting support 5 is fixed to the bottom surface of the mounting base frame 1. The movement of the nut 15 will drive the slide rail 16 to move, which will further drive the rotating shaft 17 to move left and right. The rotating shaft 17 can only rotate along the circumference of the rotary lock 6, thereby causing the rotary lock 6 to rotate.

[0014] like Figure 6 As shown, the rotary lock 6 includes a rotating shaft 61 and a lever 62. The lever 62 is fixed on the lower end of the rotating shaft 61. A corresponding through hole or slot is opened in the special iron core annealing tray to insert the rotary lock 6. The lever 62 is inserted into the special iron core annealing tray. The lever 62 rotates to limit the bottom of the special iron core annealing tray and fixes the special iron core annealing tray on the upper end of the lever 62, thereby stably hoisting the special iron core annealing tray.

[0015] like Figure 4As shown, the bottom of the mounting base frame 1 is also connected to the mounting base 8. The mounting base 8 has a guide rod 7 that slides up and down inside. The guide rod 7 is used to be inserted into the positioning hole of the special iron core annealing tray for positioning and guidance.

[0016] like Figure 1 , 3 As shown in Figure 4, a pulley bracket 2 is fixed or welded to the upper surface of the mounting base frame 1 by screws. The pulley bracket 2 includes two side plates, and a pulley shaft 3 is rotatably connected between the two sides. A pulley 4 is sleeved on the pulley shaft 3. The pulley 4 rotates on the pulley shaft 3 and a steel wire rope is wound on the pulley 4 for lifting and lowering the special iron core annealing tray.

[0017] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
