It is mainly used to control the closing of the circuit to ensure the normal operation of the power system. The closing coil is an electromagnetic coil. When current passes through it, the coil generates a magnetic field, which drives the robotic arm or other components to close the switch. It is usually fixed by bolts. Due to the small space inside the switchgear, disassembly and assembly are very inconvenient, and there is a risk of bolts falling off during the disassembly and assembly process, making it difficult to remove.

[0023] The drive assembly includes a battery 7, which is fixedly installed inside the housing 1 and electrically connected to a control switch 4. A servo motor 8 and a reducer 9 are also fixedly installed inside the housing 1. The control switch 4 is electrically connected to the servo motor 8. The output shaft of the servo motor 8 is fixedly connected to the input shaft of the reducer 9. A first rotating shaft 10 is fixed to the output shaft of the reducer 9. Specifically, the operator can control the servo motor 8 to run through the control switch 4. When the servo motor 8 runs, it can drive the first rotating shaft 10 to rotate in both directions.

[0024] The end of the first rotating shaft 10 passes through the cylinder 2 and extends into the end cover 3. The surface of the first rotating shaft 10 is rotatably connected to the inner surface of the cylinder 2 through the first bearing 11. That is, under the action of the first bearing 11, the rotational stability of the first rotating shaft 10 can be effectively improved. A bevel transmission gear 12 is fixed at the end of the first rotating shaft 10. The upper and lower ends of the end cover 3 are rotatably mounted with a second rotating shaft 14 through the second bearing 13.

The bottom end of the second rotating shaft 14 is fixed at the center of the top of the connecting seat 5. Specifically, when the servo motor 8 runs and drives the first rotating shaft 10 to rotate in both directions, the bevel transmission gear 12 and the bevel driven gear 15 can drive the second rotating shaft 14 to rotate in both directions synchronously, thereby driving the connecting seat 5 to rotate in both directions.

[0025] The bolt removal and installation assembly includes a hexagonal cutter head 16, with a square connecting block 17 fixed at the center of the top of the hexagonal cutter head 16. The square connecting block 17 is inserted into the square slot 6, and the square connecting block 17 is fixedly connected to the connecting seat 5 by a fixing bolt 18. Specifically, when the connecting seat 5 rotates in both directions, the hexagonal cutter head 16 can be driven to rotate in both directions synchronously through the square connecting block 17, so that the bolts of the electromagnetic coil can be removed and installed in both directions. It is convenient to use and can also meet the needs of the operating mechanism of the switch cabinet in a small space. Moreover, the operator only needs to remove and install the fixing bolt 18 to control the removal and installation between the square connecting block 17 and the connecting seat 5, so that the hexagonal cutter head 16 and the connecting seat 5 can be easily removed and installed, thus making it easy to replace different sizes of hexagonal cutter heads 16 to remove and install different types of bolts on the closing coil.

[0026] The magnetic suction assembly includes an opening slot 19, which is located at the center of the bottom of the hexagonal cutter head 16. A magnet 20 is fixed inside the opening slot 19. Specifically, under the magnetic attraction of the magnet 20, the bolt can be effectively magnetically attracted, thereby effectively preventing the bolt from falling off during disassembly and assembly.

[0027] The usage process of this utility model is as follows: The operator can control the servo motor 8 to run through the control switch 4. When the servo motor 8 runs, it can drive the first rotating shaft 10 to rotate in both directions. When the servo motor 8 runs and drives the first rotating shaft 10 to rotate in both directions, the second rotating shaft 14 can be driven to rotate in both directions synchronously through the bevel transmission gear 12 and the bevel driven gear 15, thereby driving the connecting seat 5 to rotate in both directions. When the connecting seat 5 rotates in both directions, the hexagonal cutter head 16 can be driven to rotate in both directions synchronously through the square connecting block 17, so that the bolts of the electromagnetic coil can be rotated in both directions for disassembly and assembly. It is convenient to use and can also meet the needs of the operating mechanism of the switch cabinet in a small space. The operator only needs to disassemble and assemble the fixing bolt 18 to control the disassembly and assembly between the square connecting block 17 and the connecting seat 5, so that the hexagonal cutter head 16 and the connecting seat 5 can be easily disassembled and assembled, so as to facilitate the replacement of different sizes of hexagonal cutter heads 16 to disassemble and assemble different types of bolts on the closing coil. Moreover, under the magnetic attraction of the magnet 20, the bolts can be effectively attracted, thereby effectively preventing the bolts from falling off during the disassembly and assembly process.
