[0047] When disassembling and overhauling the GIS circuit breaker operating mechanism, in order to enable the replacement platform to assist in receiving the disassembled parts without moving the parts to other positions, an overhaul receiving device 9 is provided at the upper end of the bottom cross bar 3. First, the staff can hold the rotating wheel 92 provided on the right side of the box body 91 to rotate the rotating wheel 92 to rotate the first gear disc 9311 provided inside the two-way component 931 counterclockwise. As the first gear disc 9311 rotates, the second gear disc 9312 engaged with the other end of the first gear disc 9311 rotates clockwise. In this way, the first gear disc 9311 and the second gear disc 9312 can realize synchronous two-way opposite rotation, and the first swing arm 9313 connected to the upper ends of the first gear disc 9311 and the second gear disc 9312 can realize the outer movement of the movable plate 9314 connected to the upper ends. The second swing arm 9315 connected to one side of the bottom can also be driven to swing synchronously with the first swing arm 9313 during the outward movement of the two side movable plates 9314, so as to enhance the stability of the outward movement of the two side movable plates 9314, so that the two side movable plates 9314 are in a stable outward movement state. With the outward push of the two side movable plates 9314, the protective box 9321 docked at the outer ends of the two side movable plates 9314 will realize synchronous outward movement along the front and rear sides of the box body 91, so as to pre-outward push the receiving box body 94 arranged at the upper end of the protective box 9321, so that the receiving box body 94 has an outward movement avoidance space and does not contact and block the mounting plate frame 8 installed on the mounting plate frame 8.

[0048] As the movable plates 9314 on both sides are pushed outward, when the protective boxes 9321 on both sides are moved outward, the plug-in shaft 93210 plugged into one end of the first lifting rods 9323 on both sides can be driven and matched with the transmission grooves 95 opened at the front or rear ends of the box body 91, so that the plug-in shaft 93210 can move upward along the inclined transmission grooves 95. At the same time, in conjunction with the auxiliary grooves 93211 opened on both sides of the outer end of the protective box 9321, the plug-in shaft 93210 can be moved upward as a whole. The auxiliary groove 93211 and the transmission groove 95 are used to guide the first lifting rod 9323 to lift up. When the first lifting rod 9323 is lifted up, the first transmission plate 9324 connected to one side of the first lifting rod 9323 will realize the lifting transmission of the inner connecting plate 9328. As the connecting plate 9328 moves up and down, the second transmission plate 9327 connected to the lower end of the connecting plate 9328 will realize the synchronous upward movement. The second transmission plate 9327 moves upward, and the second lifting rod 9325 connected to the outer end of the first transmission plate 9324 can cooperate with the third lifting rod 9326 connected to the outer end of the second transmission plate 9327 to realize the lifting of the connected top rod 9329 on the other side of the first transmission plate 9324 and the second transmission plate 9327, so that the top rod 9329 lifts the receiving box 94 connected at the upper end, and lifts the receiving box 94 out of the protective box 9321 to carry out the receiving and maintenance of the disassembled parts of the GIS circuit breaker operating mechanism. In this way, the linkage coordination of the outward avoidance of the receiving box 94 and the synchronous rising height adjustment activities can be conveniently realized, and the convenience of the structural drive can be enhanced without too many cumbersome steps to ensure that a stable receiving space can be provided when the disassembled parts of the GIS circuit breaker operating mechanism are repaired, providing convenient support for the subsequent disassembly, maintenance and reassembly of the GIS circuit breaker operating mechanism.

[0049] At the same time, when the first toothed disc 9311 and the second toothed disc 9312 are meshed and transmitted, the connecting rod 9316 connected at the upper end will be pushed, so that the connecting rod 9316 is driven and rotated from the inclined installation state to the vertical state. In this way, the upper top plate 9331 connected to the outer ends of the connecting rods 9316 on both sides will automatically move up along the inside of the box body 91. Driven by the upward movement of the upper top plate 9331, the connecting rings 9332 installed on the left and right sides of the upper top plate 9331 will cooperate with the guide plates 9333 connected at the outer ends to ensure the stability of the upper top plate 9331 during the upward or downward movement. At the same time, the connecting ring 9332 will cooperate with the connecting shaft 9335 provided on one side of the interior to transmit the spiral groove 93310 provided on the outer side of the upper end of the rotating shaft 9334, so that the rotating shaft 9334 can realize automatic rotation when the upper top plate 9331 moves up, and when the rotating shaft 9334 rotates, the rotating shaft 9334 connected to the rotating shaft 933 The screw rod 9337 at the lower end will rotate synchronously to realize the telescopic transmission of the outer threaded connection pipe 9338, so that the connection pipe 9338 moves vertically downward to push down the support plate 9339 connected at the bottom, so that the support plate 9339 contacts with the ground, thereby improving the stability of the replacement platform and avoiding the occurrence of unstable center of gravity of the replacement platform when the protective box 9321 moves outward.

Secondly, when the moving plates 9314 on both sides are moved outward, the upper plate 9331 will move up to the middle of the upper end of the box body 91 to contact with one end of the moving plates 9314 on the left and right sides, so as to realize the linkage combination of the two-way pushing transmission step and the upward transmission support step.

[0050] Please refer to Figures 11-12. The receiving box body 94 in this embodiment includes a receiving box 941 that is movably embedded in the protective box 9321 to receive the circuit breaker parts, and symmetrically arranged on the left and right sides of the receiving box 941 for folding and collecting the receiving slots 942 for matching. Correspondingly, a supporting plate 943 is installed inside the collecting slots 942 on both sides to support the maintenance tools. A row of docking holes 944 is arranged along the middle of the supporting plate 943. In this way, the docking holes 944 can be used to conveniently place and use tools such as screwdrivers and wrenches. The placement grooves 945 are symmetrical on the front and rear sides of the upper end of the support plate 943, and the disassembled small parts can be placed through the placement grooves 945 to avoid the loss of small parts. The pin shaft 946 is connected to the lower end of the support plate 943 and is rotatably connected to the inside of the collecting groove 942. In this way, the support plate 943 can be in a rotated and folded state. The counterweight blocks 947 are symmetrically fastened to the two sides of the outer side of the support plate 943. Through the counterweight cooperation of the counterweight blocks 947, the support plate 943 can be conveniently opened when the receiving box 941 is moved out of the protective box 9321.

[0051] Specifically, the counterweight block 947 is arranged in a semi-arc block shape along the outer side of the support plate 943, and the outer surface of the counterweight block 947 is polished smoothly without barbs, ensuring that the counterweight block 947 can increase the weight of the support plate 943 to achieve automatic expansion and at the same time, does not cause obstruction during subsequent closing.

[0052] When the receiving box 94 moves to the inside of the protection box 9321, the supporting plates 943 installed in the receiving slots 942 on the left and right sides of the receiving box 941 will cooperate with the counterweights 947 provided on both sides of the outer end to realize automatic opening activities to open to the horizontal support state. In this way, the docking holes 944 and placement slots 945 respectively provided in the middle part and the front and rear sides of the supporting plate 943 can realize the convenient placement of maintenance tools and small parts disassembled by the circuit breaker, making the disassembly and maintenance process of the GIS circuit breaker operating mechanism faster and more convenient;

[0053] When the first toothed disc 9311 and the second toothed disc 9312 subsequently engage in reverse meshing transmission to cooperate with the first swing arm 9313 and the second swing arm 9315 to realize the return and reset of the movable plates 9314 on both sides, the linkage reset transmission of the stabilizing structure 933 and the lifting assembly 932 can be indirectly realized, and the receiving box 941 can also be moved down again and recovered into the protective box 9321. During the downward movement of the receiving box 941, the protective box 9321 will squeeze the support plates 943 opened on both sides, so that the support plates 943 cooperate with the pin shaft 946 installed at the bottom to realize the rotation activity and automatically recover them into the collecting groove 942. In addition, during the collection process, the counterweight blocks 947 installed on both sides of the outer end of the support plate 943 will be correspondingly inserted into the left and right sides of the upper end of the protective box 9321 to assist in locking the support plate 943 as a whole to prevent the support plate 943 from automatically turning outward.
