Detailed Implementation
[0043] In the embodiments of this application, such as Figure 1 , 2 As shown in Figures 3 and 4, a rotating support for vertically supporting a GCB arc-extinguishing chamber includes a base frame 2. The bottom of the base frame 2 is provided with several casters 1. The casters 1 are existing caster structures, such as swivel wheels with brakes and other commonly used wheels. The casters 1 easily achieve flexibility and wear resistance, and improve the mobility and efficiency of the equipment.
[0044] A rotating plate 3 is rotatably connected to the top of the base frame 2. The GCB arc-extinguishing chamber is placed on top of the rotating plate 3. During use, the angle of the GCB arc-extinguishing chamber can be adjusted by rotating the rotating plate 3, which facilitates maintenance.
[0045] Furthermore, the base frame 2 includes a base plate 201, casters 1 are located at the bottom of the base plate 201 to provide mobility for the base frame; a base 202 is provided on the top of the base plate 201, and several reinforcing plates 203 are provided between the base 202 and the base plate 201; the reinforcing plates 203 enhance the connection strength between the base 202 and the base plate 201 and improve the stability of the entire base frame 2.
[0046] A connecting mechanism 4 is provided between the rotating plate 3 and the base 202; the connecting mechanism 4 is provided between the rotating plate 3 and the base 202 to realize the rotational connection between the rotating plate 3 and the base 202; specifically, the connecting mechanism 4 includes a rotating sleeve 401 fixed to the bottom of the rotating plate 3, the rotating sleeve 401 is sleeved on the outside of the base 202, so that the rotating plate 3 can rotate around the base 202.
[0047] A stabilizing sleeve 402 is provided between the rotating sleeve 401 and the base 202. The stabilizing sleeve 402 plays a role in stabilizing rotation, reducing shaking during rotation, and increasing the stability of the rotation of the rotating sleeve 401 and the transmission plate 601. A limiting ring is provided at the bottom inner side of the rotating sleeve 401, and a limiting groove adapted to the limiting ring is provided at the bottom of the stabilizing sleeve 402. A first bearing 403 is provided between the limiting ring and the stabilizing sleeve 402, and a second bearing 404 is provided between the bottom of the rotating sleeve 401 and the base 202. The first bearing 403 and the second bearing 404 are preferably planar bearings. During the rotation of the rotating plate 3 and the rotating sleeve 401, the force is applied to the first bearing 403 and the second bearing 404, which can ensure the stability of rotation.
[0048] In the preferred embodiment, the base 202 is a platform, and a cover plate 405 is provided at the top of the base 202. The outer periphery of the top of the base 202 is threaded, and the cover plate 405 is connected to the base 202 through the thread. The cover plate 405 abuts against the stabilizing sleeve 402. A positioning ring 406 is provided at the bottom of the cover plate 405, which extends into the interior of the stabilizing sleeve 402. The positioning ring 406 is used to stabilize the position of the stabilizing sleeve 402 and prevent the stabilizing sleeve 402 from wearing the threads. When it is necessary to replace the first bearing 403 and the second bearing 404, etc., the cover plate 405 is unscrewed, and then the cover plate 405 can be removed. Then the positioning ring 406 can be removed, and finally the rotating plate 3 and the base frame 2 can be separated for the user to replace and maintain.
[0049] In a further embodiment, a transmission rod 5 is provided inside the base 202, and the top end of the transmission rod 5 is connected to the rotating plate 3. A drive mechanism for driving the transmission rod 5 to rotate is also provided. The transmission rod 5 includes a rotating shaft 501 rotatably mounted inside the base 202. A first transmission block 502 is provided at the bottom of the rotating shaft 501; a plug-in block 503 is provided at the top of the rotating shaft 501, and the plug-in block 503 is located at the top of the base frame 2. The plug-in block 503 is a polygonal column. The polygonal column design can prevent relative rotation between the plug-in block 503 and the connecting frame 6, ensuring effective power transmission. The plug-in block 503 is connected to the rotating plate 3 through the connecting frame 6. The connecting frame 6 includes a transmission plate 601, and a plug-in block 503 is inserted into the interior of the transmission plate 601. The transmission plate 601 has a plug-in hole that matches the plug-in block 503. The transmission plate 601 is movably mounted on the base frame 2. Several connecting rods 602 are provided on the outer periphery of the transmission plate 601. The connecting rods 602 are connected to the rotating plate 3 by screws. The connecting frame 6 realizes a stable connection between the transmission rod 5 and the rotating plate 3, ensuring the synchronicity and stability of the rotation.
[0050] In operation, power is transmitted between the drive mechanism and the rotating plate 3 via the transmission rod 5. The drive mechanism includes a fixed base 701, within which a motor 702 is housed. The output shaft of the motor 702 is equipped with a second transmission block 703. The second transmission block 703 is connected to the first transmission block 502. The motor 702 serves as the power source, driving the transmission rod 5 to rotate through the transmission between the transmission blocks, thereby achieving the rotation of the rotating plate 3. The second transmission block 703 and the first transmission block 502 are mutually cooperating magnets, utilizing magnetic force for transmission. This eliminates the need for complex mechanical connections, reduces mechanical wear, and improves the reliability and stability of the transmission.
[0051] In another embodiment, by setting the fixed base 701 at a fixed work position, preferably a maintenance work position, the GCB arc-extinguishing chamber to be repaired is placed on top of the rotating plate 3, and then pushed above the fixed base 701 by the caster 1 until the second transmission block 703 and the first transmission block 502 are connected, and the caster 1 is fixed, then maintenance can be carried out. After the maintenance is completed, it is removed, and then the next GCB arc-extinguishing chamber to be repaired is pushed in, so that uninterrupted continuous maintenance can be completed, which is convenient for situations with a large number of maintenance.
