[0018] The present invention realizes the rapid formation of the replacement platform by setting the supporting longitudinal rod, universal wheels, bottom cross bar, reinforcing rib plate, receiving plate, vertical rod, upper cross bar and mounting plate frame, so as to stably assemble and conveniently disassemble and repair the operating mechanism of the GIS circuit breaker. And a maintenance receiving device is set. That is, under the dual combination drive set inside the box body, the synchronous outward movement of the protective boxes arranged on the front and rear sides of the box body can be realized. And during the outward movement process, by cooperating with the insertion shaft, auxiliary groove and transmission groove, the receiving box body is jacked up, so that the receiving box body can be used for disassembling, receiving and repairing the operating mechanism of the GIS circuit breaker, and the maintenance tools can be conveniently placed through the receiving box body, thus achieving the advantages of stable formation of the replacement platform for adapting to replacement and repair use and auxiliary receiving and repair cooperation.

[0019] The setting of the two-way opening and closing component, that is, under the meshing drive of the first gear disk and the second gear disk, the first swing arm and the second swing arm can cooperate to realize the two-way synchronous outward push of the moving plates arranged on both sides of the upper end of the box body. Thus, the protective boxes arranged on the front and rear sides of the box body are pushed outward to avoid contact between the receiving box body arranged on the protective box and the circuit breaker.

[0020] The setting of the stable structure, that is, when the first gear disk and the second gear disk are meshing and driving, the connecting rod connected to the upper end can be driven, so that the connecting rod pushes up the upper top plate. The upper top plate can realize stable upward movement through the connection between the connection rings arranged on the left and right sides and the guide plate. At the same time, under the drive of the connection shaft arranged inside the connection ring and the spiral groove opened outside the rotating shaft, the screw rod arranged at the lower end of the rotating shaft and the connecting pipe can be in threaded drive, so that the support plate moves downward and contacts the ground to realize the auxiliary support and stable cooperation, avoiding the occurrence of the phenomenon of unstable center of gravity.

[0021] The setting of the lifting component, that is, when the two protective boxes move outward along with the two moving plates, through the cooperation of the insertion shaft, the auxiliary groove and the transmission groove, the first rod body and the first transmission plate can be in transmission cooperation. Thus, the connecting plate is lifted. The connecting plate can cooperate with the first transmission plate and the second transmission plate to realize the upward lifting transmission of the second rod body and the third rod body. In this way, the first transmission plate and the second transmission plate will realize the upward push transmission of the ejector rod connected to one side, so that the ejector rod moves outward along with the protective box, realizing the linkage upward push and outward movement of the receiving box body connected to the upper end.

[0022] The setting of the receiving box body, that is, the receiving box shell assists in realizing the receiving and maintenance cooperation of the disassembled circuit breaker parts. And the supporting plates arranged at the receiving grooves on the left and right sides of the receiving box can be weighted with the counterweights arranged outside, and automatically unfold along with the outward movement of the receiving box. Thus, the placement of maintenance tools or small parts is realized, making the circuit breaker maintenance process more convenient and reducing the occurrence of messy and cumbersome disassembly and assembly problems.

In this way, when the connecting rods 9316 on both sides are driven by the first gear plate 9311 and the second gear plate 9312, convenient and stable support cooperation can be achieved.

[0041] Among them, the first toothed disc 9311 and the second toothed disc 9312 are both arranged in a semi-toothed plate shape, and the tooth groove on one side of the first toothed disc 9311 meshes with the tooth groove on one side of the second toothed disc 9312, ensuring that the first toothed disc 9311 and the second toothed disc 9312 cooperate in meshing activities to achieve two-way opening and closing transmission; two pairs of first swing arms 9313 and second swing arms 9315 are arranged along the right side of the box body 91, and the adjacent first swing arms 9313 and second swing arms 9315 are arranged symmetrically on the left and right to ensure that the two The first swing arm 9313 and the second swing arm 9315 are synchronously swung relative to or oppositely to ensure the stability of the opening and closing lifting transmission activities; the upper ends of the first swing arm 9313 and the second swing arm 9315 are movably docked with the inside of the movable plate 9314, and the outer side of the movable plate 9314 is tightly docked with the lifting component 932, so that when the first swing arm 9313 and the second swing arm 9315 swing, there is a certain avoidance space to ensure the standard of the relative or opposite movement activities of the movable plates 9314 on both sides.

[0042] Among them, the stable structure 933 includes an upper top plate 9331 built inside the box body 91 and connected to the upper ends of the two side connecting rods 9316.

A connecting shaft 9335 movably embedded in one side of the connecting ring 9332 for rotational driving. A compression spring 9336 connected to one side of the connecting shaft 9335 to provide elastic pressing support. Screws 9337 symmetrically and vertically and tightly connected to the lower ends of the two side rotating shafts 9334 to realize threaded telescopic transmission. Connecting pipes 9338 threadedly connected to the outside of the screws 9337 and vertically penetrating the two sides of the lower end of the box body 91. Vertical limiting grooves are provided on both outer ends of the connecting pipe 9338, and the connecting pipe 9338 is vertically and limitedly butted with the lower end of the box body 91 through the vertical limiting grooves provided on both outer ends. Support plates 9339 connected to the lower ends of the two side connecting pipes 9338 for supporting and stabilizing cooperation. A spiral groove 93310 provided on the outer side of the rotating shaft 9334, and the spiral groove 93310 is connected to the connecting shaft 9335 provided inside the connecting ring 9332. In this way, when the connecting ring 9332 drives the connecting shaft 9335 to move up and down, in cooperation with the spiral groove 93310, the rotation of the rotating shaft 9334 can be driven.

[0043] Among them, the connecting ring 9332 is movably embedded in the guide plate 9333, and the connecting ring 9332 is slidably sleeved on the outside of the rotating shaft 9334. In this way, the connecting ring 9332 can move up and down along the rotating shaft 9334, and through the docking transmission of the connecting shaft 9335 and the spiral groove 93310, the automatic rotational transmission of the rotating shaft 9334 is realized.

[0044] Among them, the lifting component 932 includes a protective box 9321 disposed inside the left and right sides of the box body 91 and firmly butted with the outer ends of the two moving plates 9314, a bracket 9322 installed at the lower end inside the protective box 9321 for supporting and cooperating, a first lifting rod 9323 rotatably connected to the upper end of the bracket 9322 to realize lifting transmission, a first transmission plate 9324 rotatably connected to the left side of the first lifting rod 9323, and the left lower part of the first transmission plate 9324 is bent, a second lifting rod 9325 connected to the bent end on the left side of the first transmission plate 9324 to realize auxiliary lifting support, a third lifting rod 9326 oppositely disposed at the lower end of the second lifting rod 9325, and the right side of the third lifting rod 9326 is butted with the second lifting rod 9325, and the right side of the third lifting rod 9326 is rotatably connected and cooperated with the bracket 9322, a second transmission plate 9327 rotatably connected to the left side of the third lifting rod 9326, and the second transmission plate 9327 is integrally arranged in a horizontal plate shape, a connecting plate 9328 connected between the first transmission plate 9324 and the second transmission plate 9327 and arranged vertically, a top rod 9329 connected to one end of the first transmission plate 9324 and the second transmission plate 9327 for jacking and lifting transmission, and the upper end of the top rod 9329 is connected to the receiving box body 94.

[0045] Among them, the lifting component 932 further includes a plug shaft 93210 inserted into the left side of the first lifting rod 9323 for lifting transmission, auxiliary grooves 93211 symmetrically formed on both outer sides of the protective box 9321 and in an arc-shaped groove shape, and the plug shaft 93210 can realize stable lifting transmission cooperation with the auxiliary grooves 93211. The outer end of the plug shaft 93210 is inserted into the interior of the auxiliary grooves 93211, and the outer end of the plug shaft 93210 can also be inserted into the transmission groove 95. Thus, with the guiding combination of the auxiliary grooves 93211 and the transmission groove 95, the first lifting rod 9323 can be lifted accordingly and cooperate with other parts to realize the upward transmission of the entire receiving box body 94.

[0046] Among them, the first lifting rod 9323, the first transmission plate 9324, the second lifting rod 9325, the third lifting rod 9326, the second transmission plate 9327, the top rod 9329 and the plug shaft 93210 are all symmetrically arranged on both sides of the upper end of the bracket 9322, and both ends of the first transmission plate 9324 and the second transmission plate 9327 far from the connecting plate 9328 are connected to the top rod 9329. Thus, the parts arranged inside the lifting component 932 can stably combine to lift the top rod 9329, and the top rod 9329 can stably jack up the receiving box body 94 to lift it to an appropriate height for receiving and overhauling the circuit breaker parts.

[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, the compression spring 9336 connected to one side of the connecting shaft 9335 can provide elastic force to push the connecting shaft 9335 outward, so that the connecting shaft 9335 is stably plugged into the spiral groove 93310, thereby ensuring the stability of the rotation transmission of the rotating shaft 9334. 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] See also Figures 11 - 12 The receiving box body 94 in this embodiment includes a receiving box 941 for receiving the circuit breaker parts in a correspondingly movable manner and embedded in the protection box 9321, and receiving slots 942 for folding and collecting the receiving box 941 are symmetrically arranged on the left and right sides of the receiving box 941, and a supporting plate 943 for supporting the maintenance tools is installed in the receiving slots 942 on both sides. A row of docking holes 944 are 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, and the supporting plate 943 can be used to carry tools such as screwdrivers and wrenches. The placement grooves 945 are symmetrical on the front and rear sides of the upper end, 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 947 is arranged in a semi-circular block shape along the outer side of the supporting plate 943, and the outer surface of the counterweight 947 is smooth and free of burrs after grinding, ensuring that the counterweight 947 can increase the weight of the supporting plate 943, realizing the automatic unfolding movement. At the same time, it will not cause obstruction during subsequent closing.

[0052] When the receiving box 94 moves into the protective box 9321, the supporting plates 943 installed inside the receiving grooves 942 on the left and right sides of the receiving box 941 will, in cooperation with the counterweights of the counterweights 947 provided on both outer ends, realize the automatic opening movement to open to the horizontal support state. In this way, through the docking holes 944 and the placement grooves 945 respectively opened in the middle and the front and rear sides of the supporting plate 943, the convenient placement of maintenance tools and the disassembled small parts of the circuit breaker can be realized, making the disassembly and maintenance process of the GIS circuit breaker operating mechanism faster and more convenient.

[0053] When the first gear disk 9311 and the second gear disk 9312 are reversely meshed and driven subsequently, in cooperation with the first swing arm 9313 and the second swing arm 9315, to realize the return and reset of the moving plates 9314 on both sides, the linkage reset drive of the stable structure 933 and the lifting assembly 932 can be indirectly realized. The receiving box 941 can also be moved downward and recycled into the protective box 9321 again. During the downward movement of the receiving box 941, the protective box 9321 will squeeze the opened supporting plates 943 on both sides, causing the supporting plates 943 to cooperate with the pin shafts 946 installed at the bottom to realize the rotary movement and automatically recycle into the receiving grooves 942. Moreover, during the recycling process, the counterweights 947 installed on both outer ends of the supporting plate 943 will correspondingly be inserted into the left and right sides inside the upper end of the protective box 9321 to assist in locking the whole supporting plate 943 and prevent the supporting plate 943 from automatically turning outwards.
