[0022] See also Figure 1-4 The utility model provides a technical solution: a transformer lifting tool, including a lifting frame, a transverse drive component, a limit component and a center of gravity balance component. The lifting frame includes a support frame 1, a connecting plate 2 and a top plate 3. The bottom of the connecting plate 2 is fixedly connected to the top side of the support frame 1, and the top of the connecting plate 2 is fixedly connected to the bottom side of the top plate 3. The transverse drive component includes a gear shaft 5 and a motor 7. The middle part of the gear shaft 5 is fixedly connected with a transmission shaft 6.

An annular groove is provided on both sides of the transmission shaft 6, and a connecting ring 8 is rotatably sleeved on the inner wall of the annular groove. The bottom of the connecting ring 8 is fixedly connected to a lifting ring 9. The transformer is hung on the two lifting rings 9 through cables and hooks. When the motor 7 is turned on, the gear shaft 5 rotates and moves along the tooth groove at the bottom of the inner wall of the support frame 1, driving the transformer to move horizontally in the cabinet without being affected by the cabinet top cover.

[0023] The limiting assembly includes a fixing plate 10, the bottom of which is fixedly connected to the top of the motor 7, and a connecting rod 11 is fixedly connected to one side of the fixing plate 10. A collar 12 is rotatably sleeved on one end of the connecting rod 11 away from the fixing plate 10. A strip groove 13 is provided on one side of the outer wall of the support frame 1. The bottom of the collar 12 is rotatably connected to the bottom of the inner wall of the strip groove 13. The collar 12 rolls along the inner wall of the strip groove 13 to reduce resistance. The fixing plate 10 and the connecting rod 11 limit the motor 7 to prevent the motor 7 from rotating itself.

[0024] A through opening 14 is provided on one side of the support frame 1, and a baffle 15 is fixedly connected to the opening of the through opening 14 on the outer wall of the support frame 1, and a signal transmitter 17 is fixedly connected to the middle part of the baffle 15, and a vent 16 is provided on the surface of the baffle 15. A pressure-sensitive sensor 18 is fixedly installed on the inner side of the signal transmitter 17, and a pad 19 is slidably connected to the inner wall of the through opening 14. A pressure rod 20 and a spring 21 are fixedly connected to one side of the pad 19. The end of the spring 21 away from the pad 19 is fixedly connected to the inner side of the baffle 15, and the end of the pressure rod 20 away from the pad 19 is in contact with the side of the pressure-sensitive sensor 18 away from the signal transmitter 17. When the side of the gear shaft 5 hits and squeezes the pad 19, the pressure-sensitive sensor 18 senses the pressure change and sends a signal through the signal transmitter 17 to turn off the motor 7 through the operator, and the spring 21 is used to reset the position of the pad 19;

[0025] One side of the connecting plate 2 is fixedly connected to an inclined plate 22, and the bottom of the inclined plate 22 is fixedly connected to the top of the supporting frame 1. The inclined plate 22, the connecting plate 2 and the supporting frame 1 form a triangular shape to improve rigidity;

[0026] The center of gravity balancing assembly includes a second motor 23 and a counterweight 26. The bottom of the second motor 23 is fixedly connected to one side of the top of the top plate 3. The output shaft end of the second motor 23 is fixedly connected to a threaded tube 24. The inner wall of the threaded tube 24 is threadedly connected to a screw 25. The end of the screw 25 away from the threaded tube 24 is fixedly connected to a clamping plate 27. The side of the counterweight 26 is fixedly connected to a connecting seat 28.

The bottom of the counterweight 26 is slidably connected to the top of the top plate 3. When the transformer moves laterally, the counterweight 26 moves in the opposite direction to balance the overall center of gravity.

[0027] An electronic level 29 is fixedly connected to the side of the top plate 3 away from the motor 7. The electronic level 29 has an internal integrated signal sending module. The electronic level 29 is used to measure the center of gravity offset and adjust the moving speed of the counterweight 26 to avoid excessive tilt of the whole.

[0028] The side ends of motor 1 7 and motor 2 23 are fixedly installed with remote control modules, which can remotely control the opening and closing and speed of motor 1 7 and motor 2 23;

[0029] Both sides of the top of the top plate 3 are fixedly connected with lifting rings 30 for connecting the top plate 3 to the hooks of the lifting equipment.

[0030] Working principle: Use the existing cable to fix the transformer, hang the hook of the cable on the lifting ring 9, and then hang the hook of the lifting equipment on the lifting ring 2 30. First lift the transformer vertically, and after moving the transformer to the side opening of the cabinet, adjust the height of the lifting frame so that the top plate 3 is above the top of the cabinet, and then slowly move the top plate 3 horizontally to move the support frame 1 and the transformer to a certain distance inside the cabinet. The top of the cabinet is below the top plate 3 and does not conflict with the inclined plate 22. Then remotely control the motor 17 to start the drive shaft 6 and the gear shaft 5 to rotate, driving the connecting ring 8 and the lifting ring 19 to move, thereby driving the transformer to move horizontally and change its position inside the cabinet. The ring 12 rolls along the inner wall of the strip groove 13 to reduce the resistance of the connecting rod 11 to move. The connecting rod 11 and the fixed plate 10 limit the motor 17, so that the motor 17 can drive the gear shaft 5 to rotate normally. While the gear shaft 5 moves, the electronic level 29 senses In response to the change in the overall center of gravity, a signal is sent to the operator. The operator turns on motor 23 to drive the threaded tube 24 to rotate, thereby driving the counterweight 26 to move along the top of the top plate 3 and the moving direction is opposite to the moving direction of the gear shaft 5, so as to balance the overall center of gravity and avoid excessive tilting. As the gear shaft 5 moves, the side of the gear shaft 5 hits the side of the pad 19, causing the pad 19 to slide along the inner wall of the opening 14, and the pressure rod 20 presses on the pressure-sensitive sensor 18. The pressure-sensitive sensor 18 senses the pressure change and sends a signal to the operator through the signal transmitter 17 to remotely shut down motor 1 7, so that the transformer stops moving horizontally. Finally, the lifting equipment is operated to lower the transformer into the cabinet. The horizontal movement is not hindered by the top of the cabinet, which solves the problem that most traditional transformer lifting equipment only meets the needs of vertical lifting and horizontal lifting in unobstructed directions. When the transformer needs to be transported into the cabinet, the lifting cable conflicts with the top of the cabinet and is difficult to transport.
