[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 3The utility model provides an embodiment: a transformer hanging device, including a circular plate 1, a column 2 arranged in a vertical state is fixedly connected to the top of the circular plate 1, and the surrounding surfaces of the column 2 are connected to the top of the circular plate 1 through a reinforcing beam 3 to ensure the connection strength between the column 2 and the circular plate 1, a moving block 4 is arranged at the bottom of the circular plate 1, and the moving direction of the moving block 4 is the radial direction of the circular plate 1, and a control mechanism is arranged inside the moving block 4, and a protrusion 5 is fixedly connected to the top of the moving block 4, a groove 6 is opened at the bottom of the circular plate 1, and the protrusion 5 is slidably installed on the inner wall of the groove 6, and the sliding direction of the protrusion 5 is the radial direction of the circular plate 1, and the cross-sectional shape of the protrusion 5 is set to be trapezoidal with the longer side facing upward, and the shape of the groove 6 matches the protrusion 5, so as to improve the installation stability of the protrusion 5 and prevent the protrusion 5 from detaching from the inside of the groove 6, and an adjusting mechanism is arranged inside the circular plate 1.

[0031] Reference Figure 3 The adjusting mechanism includes a pull ring 7, which is used to facilitate the staff to pull the limit rod 8 to move upward, which is convenient and labor-saving. The bottom of the pull ring 7 is fixedly connected with a limit rod 8 set in a vertical state, and the limit rod 8 is slidably installed on the inner wall of the circular plate 1. The circumferential surface of the limit rod 8 is fixedly connected to the limit plate 9. The top of the limit plate 9 is elastically connected to the top of the inner wall of the circular plate 1 through a spring 10. By setting a spring 10, a limit force is applied to the limit plate 9 toward the bottom. A limit hole 11 matching the limit rod 8 is opened on the top of the protrusion 5. The number of limit holes 11 is set to multiple, and multiple limit holes 11 are arranged at the top of the protrusion 5 in a straight line with equal spacing. Through the cooperation of the limit rod 8 and the limit hole 11, the moving block 4 can be moved while ensuring the connection stability of the moving block 4 and the circular plate 1. A main hook 20 is provided at the bottom of the circular plate 1.

[0032] Reference Figure 2 - Figure 4 The control mechanism includes a threaded rod 13, which is threadedly mounted on the inner wall of the moving block 4. Through the effect of thread conversion, the threaded rod 13 rotates and also makes a linear motion in the radial direction of the circular plate 1. The number of threaded rods 13 is set to multiple, and the ends of the multiple threaded rods 13 that are away from each other are fixedly connected with a knob 12. The knob 12 is used to increase the friction with the staff's hand to facilitate the rotation of the threaded rod 13. The control mechanism also includes a pressure block 14, which is slidably mounted on the inner wall of the moving block 4. The sliding direction of the pressure block 14 is the radial direction of the circular plate 1. The pressure block 14 and the threaded rod 13 are rotatably connected. The rotation of the threaded rod 13 drives the pressure block 14 to move linearly. The control mechanism also includes a slider 16, which is slidably mounted on the inner wall of the moving block 4. The sliding direction of the slider 16 is the radial direction of the circular plate 1. The slider 16 is elastically connected to the pressure block 14 through a spring 2 15. The spring 2 15 is initially set to a stretched state. By setting the spring 2 15, the slider 16 and the pressure block 14 have a tendency to approach each other.

[0033] Reference Figure 2 - Figure 4 The control mechanism also includes a pull rope 17. The material of the pull rope 17 can be a metal material with good tensile resistance to ensure the stability of the transformer hanging. One end of the pull rope 17 is fixedly connected to the surface of the slider 16, and the other end of the pull rope 17 is fixedly connected to a secondary hook 19. The control mechanism also includes a fixed pulley 18, which is used to change the transmission direction of the pull rope 17 without changing the tension of the pull rope 17 in various directions. The fixed pulley 18 is rotatably installed on the inner wall of the moving block 4. The circumferential surface of the pull rope 17 contacts the circumferential surface of the fixed pulley 18. The displacement of the slider 16 drives the secondary hook 19 to move up and down through the transmission of the pull rope 17.

[0034] Working principle: When in use, the transformer is placed under the circular plate 1, and then the main hook 20 and the auxiliary hook 19 are connected to the connecting hole above the transformer, and then the position of each movable block 4 at the bottom of the circular plate 1 is adjusted according to the size of the transformer. When adjusting the position of the movable block 4, the pull ring 7 is pulled upward, and the movement of the pull ring 7 drives the limit rod 8 to move upward. The displacement of the limit rod 8 drives the limit plate 9 to overcome the elastic force of the spring 10 and move upward, thereby causing the limit rod 8 to detach from the inner wall of the limit hole 11, and then the position of the movable block 4 can be adjusted conveniently and quickly, so that it is best to keep the vertical state when the pull rope 17 is tightened, and then the pull ring 7 is released, so that the limit rod 8 is re-stuck in the inside of the limit hole 11 under the elastic force of the spring 10, and the movable block 4 is fixed relative to the circular plate 1 to ensure the stability of the equipment when it is working.

[0035] According to the different tensions adapted to different types of transformers, the knob 12 is rotated, and the rotation of the knob 12 drives the threaded rod 13 to rotate, and the rotation of the threaded rod 13 drives the pressure block 14 to move away from the center of the circular plate 1, so that the length of the spring 2 15 is stretched, and the elastic force applied by the spring 2 15 to the slider 16 is increased, so that the pull rope 17 is tightened, and the transmission effect of the pull rope 17 increases the tension applied by the auxiliary hook 19 to the transformer, thereby improving the accuracy of the tension control, and can adapt to transformers of various types and weights.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
