Description

Technical Field

[0001] This invention relates to the field of porcelain column circuit breaker manufacturing, and particularly to a testing system for porcelain column circuit breaker manufacturing. Background Technology

[0002] High-voltage circuit breakers (or high-voltage switches) can not only interrupt or close the no-load current and load current in high-voltage circuits, but also, when a system fault occurs, interrupt overload current and short-circuit current through the action of relay protection devices. They possess a highly sophisticated arc-extinguishing structure and sufficient breaking capacity. High-voltage circuit breakers can be classified according to their arc-extinguishing connection, such as oil circuit breakers, air circuit breakers, vacuum circuit breakers, and sulfur hexafluoride circuit breakers. According to their operating nature, they can be classified as electric mechanism, pneumatic mechanism, hydraulic mechanism, spring energy storage mechanism, and manual mechanism. According to their structural type, they can be classified as porcelain column type and tank type. Tank type circuit breakers are suitable for areas with high seismic intensity, high altitude and cold weather, and severe pollution; porcelain column type circuit breakers are suitable for general areas. According to their operating method, they can be classified as phase-by-phase operation and three-phase mechanical linkage. Circuit breakers of 330kV and above mostly adopt phase-by-phase operation, 220kV circuit breakers can adopt three-phase mechanical linkage or phase-by-phase operation, and circuit breakers of 110kV and below mostly adopt three-phase mechanical linkage.

[0003] Porcelain column circuit breakers are important equipment for ensuring the safe operation of ultra-high voltage or extra-high voltage power systems. The circuit breaker's break point is supported at the top by a porcelain column, which serves both as insulation and as a support component.

[0004] During the production of porcelain column circuit breakers, after the circuit breaker is assembled, its performance needs to be tested. For example, porcelain column circuit breakers usually use sulfur hexafluoride gas as internal insulation and arc extinguishing medium. Therefore, leakage testing is required to ensure the product is qualified. In addition, there are withstand voltage tests, etc.

[0005] Currently, the testing of porcelain-column circuit breakers is usually conducted in two separate steps: first, a withstand voltage test or a leak test is performed, and then the circuit breaker is moved to another location for another test. However, due to the inherent structural characteristics of porcelain-column circuit breakers, they are bulky. Therefore, during testing, firstly, sufficient space needs to be reserved for moving the circuit breaker; secondly, the issue of moving the circuit breaker itself is problematic. Because of its large size, moving the circuit breaker requires multiple methods such as flatbed trucks and overhead cranes, which is very cumbersome. Furthermore, moving flatbed trucks and overhead cranes also requires a significant amount of space. Finally, testing the circuit breaker in two different locations may result in missed tests. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a testing system for the production of porcelain column circuit breakers, which can facilitate the withstand voltage and leak detection tests of circuit breakers and avoid the occurrence of missed detections.

The anti-tipping component includes an anti-tipping plate, which is located above the second conveyor roller. A cuboid groove is also opened at the bottom end of the anti-tipping plate. The cuboid groove and the second conveyor roller work together to form a pair of pallets for limiting the anti-tipping cavity.

[0023] Furthermore, an abnormality handling unit is also provided on the other side of the conveying guide rail located in the leak detection room. The abnormality handling unit includes a handling bracket, a top crossbeam is connected to the top of the handling bracket, and a handling platform is installed on the handling bracket.

[0024] A third conveyor roller group is provided on each side of the processing platform. The third conveyor roller group includes several third conveyor rollers arranged in parallel, and each third conveyor roller rotates synchronously and in the same direction by the cooperation of sprockets and chains.

[0025] A third plate is also provided on the processing platform between the two sets of third conveyor rollers, and the height of the upper end face of the third plate is lower than the height of the top of the third conveyor roller.

[0026] A pair of lifting mechanisms are also provided between the processing platform and the top crossbeam. The lifting mechanism includes a lifting bracket and a lifting plate is installed on the lifting bracket. The lifting plate is a U-shaped plate and the openings of the two lifting plates are arranged opposite each other. The lifting bracket is driven by the lifting mechanism to move up and down.

[0027] Furthermore, the lifting mechanism comprises: a vertically arranged lifting guide rail installed on both sides of the treatment bracket; a lifting slider that cooperates with the lifting guide rail installed on the support bracket; a vertically arranged lifting screw installed on the treatment bracket; the lifting screw being driven to rotate by a lifting motor installed on the treatment bracket; and a screw nut that cooperates with the lifting screw installed on the support bracket; the support bracket moving up and down along the lifting guide rail under the drive of the lifting screw.

[0028] Furthermore, the flipping machine includes

[0029] Flip rack;

[0030] A flipping platform is horizontally mounted on a flipping frame. One side of the flipping platform is hinged to the flipping frame, and the other side lies flat on the flipping frame. The flipping platform is driven to flip by a flipping mechanism mounted on the flipping frame.

[0031] A support base is installed on the tilting platform. The support base is located near the side where the tilting platform is hinged to the tilting frame. The support base includes a support frame and a support plate mounted on the support frame. There is a pair of support plates, which are distributed on both sides of the support frame along the width direction of the tilting platform. The support plates are L-shaped and the two support plates are arranged opposite to each other. A limiting groove for accommodating the lower flange seat is also opened on the adjacent side of the two support plates. The limiting grooves on the two support plates work together to achieve limiting support for the lower flange seat.

[0032] A clamping assembly is installed on a flipping platform. Several clamping assemblies are arranged sequentially along the long axis of the flipping platform. Each clamping assembly includes a pair of clamping plates arranged side by side on both sides of the width of the flipping platform. The two clamping plates are driven to move closer or further apart by a horizontal mechanism installed on the flipping platform.

[0033] Several auxiliary support platforms are also installed on the flipping platform. The auxiliary support platforms are located on the center line of the flipping platform, and each auxiliary support platform is arranged in sequence along the long axis of the flipping platform. A support groove is also opened on the upper surface of the auxiliary support platform. The support groove is in the shape of an isosceles trapezoid, and the length of the upper base of the support groove is longer than the length of the lower base of the support groove.

[0034] Furthermore, the horizontal mechanism is as follows: a pair of translation guide rails corresponding to and cooperating with the two clamping plates are respectively installed on both sides of the width direction of the flipping platform. The two translation guide rails are distributed side by side along the long axis of the flipping platform and extend along the width direction of the flipping platform. A translation slider that cooperates with the two translation guide rails is installed at the bottom end of the clamping plate. The clamping plates are brought closer or further apart by the cooperation of gears and racks installed on the flipping platform.

[0035] Furthermore, the engagement between the clamping plates and the gears and racks is as follows: a rack is installed at the bottom end of each of the two clamping plates, and the racks are located between the two translation guides. The racks extend along the width of the flipping platform, and both racks extend to the center of the flipping platform and overlap. A gear is installed at the center of the flipping platform that meshes with both racks. The gears are driven to rotate by a translation motor installed on the flipping platform, which drives the two racks to move synchronously in opposite directions, thereby driving the two clamping plates to move closer or further apart.

[0036] The advantages of this invention are as follows: The testing system of this invention, through the cooperation between the conveying unit, the assembly unit, the inflation unit, the leak detection unit, the withstand voltage test unit, and the supervision unit, uses the conveying unit as the intermediate medium for transmission, so as to realize the sequential turnover of the porcelain column circuit breaker between different units, which facilitates the circuit breaker to perform withstand voltage and leak detection tests and avoids the occurrence of missed detection.

[0037] The assembly platform is designed with the second conveyor roller and the second flat plate working together to support the pallet. This facilitates the movement of the pallet on the assembly platform and allows personnel to stand on the second flat plate to operate the circuit breaker. The height of the second flat plate is designed to be lower than the top of the second conveyor roller to avoid interference with the conveying action. The sealing plate between the second conveyor rollers is designed to eliminate gaps between adjacent rollers, preventing the pallet from jamming during transport. The airbag buffer is designed to position and fix the pallet after it is in place, preventing it from moving back and forth on the second conveyor roller during subsequent operations and interfering with normal operations.

[0038] In addition, the anti-tipping component is designed to limit the pallet by using an anti-tipping plate and a second conveyor roller together to form an anti-tipping cavity, thus preventing the pallet from tipping over when it is being transported on the second conveyor roller.

[0039] The large circuit breaker is flipped by the combined action of the flipping frame, flipping platform, support base, auxiliary support platform and clamping components. The whole process is mechanical, which greatly reduces the need for manpower and material resources and can quickly flatten the circuit breaker pole.

[0040] The auxiliary support platform is designed to provide auxiliary support for large circuit breakers. On the other hand, it can also provide main support for large circuit breakers after they are laid flat. This reduces the clamping force of the clamping plate on the large circuit breaker, or even eliminates the need for clamping force, thus avoiding damage to the pole column caused by prolonged clamping.

[0041] The tilting mechanism is designed with a pair of tilting cylinders working together to tilt the platform, making the platform more stable during movement and reducing the load on a single tilting cylinder. In addition, the hinge point between the tilting cylinder and the tilting platform is designed to be on the side closer to the hinge between the tilting platform and the tilting frame, which reduces the stroke requirement of the tilting cylinder.

[0042] The horizontal mechanism is designed so that the translation of a single clamping plate is achieved by the cooperation of a pair of translation guide rails, which makes the translation of the clamping plate more stable, avoids deviation, and ensures the clamping of large circuit breakers.

[0043] For the engagement between the clamping plate and the gears and racks, two racks that extend to the center of the flipping platform and overlap are used to engage with the gears. This drive method only requires the engagement of one gear and one motor to move the two clamping plates closer or further apart, reducing the number of transmission components and active drive components, simplifying the structure and reducing energy consumption.

[0053] The following embodiments are intended to enable those skilled in the art to more fully understand the present invention, but do not limit the invention to the scope of the embodiments described.

[0054] like Figures 1-8The diagram shows a testing system for manufacturing porcelain-column circuit breakers. The porcelain-column circuit breaker includes a base, an operating mechanism, an upper pole 12, and a lower pole 14. An upper flange seat 11 is connected to the top of the upper pole 12, a contact seat 13 is connected between the upper pole 12 and the lower pole 14, and a lower flange seat 15 is connected to the bottom of the lower pole 14. The lower flange seat 15 is fixed to the base, and the operating mechanism is mounted on the base.

[0055] The testing system includes

[0056] The conveying unit includes a conveying guide rail 101 and a shuttle 107 that reciprocates on the conveying guide rail 101.

[0057] like Figure 2 As shown in the schematic diagram, the shuttle 107 includes a shuttle body 701, on which a transfer platform 702 is provided. The transfer platform 702 is a rectangular frame. On both sides of the long axis of the transfer platform 702, a first conveying roller group is provided. The first conveying roller group includes several first conveying rollers 703 arranged in parallel along the width of the transfer platform 702. The two sides of the first conveying rollers 703 are movably mounted on the transfer platform 702 through the cooperation of bearings and bearing seats. Each first conveying roller 703 is synchronously rotated in the same direction by the cooperation of sprockets and chains. Any one of the first conveying rollers 703 is driven to rotate by a motor installed on the transfer platform 702, which drives all the first conveying rollers 703 to rotate synchronously. The conveying directions of the two groups of first conveying rollers are the same.

[0058] A first flat plate 704 is also provided on the transfer platform 702 between the two sets of first conveying rollers. The first flat plate 704 is a rectangular plate, and the height of the upper end of the first flat plate 704 is lower than the height of the top of the first conveying roller 703, so as to avoid the first flat plate 704 interfering with the pallet and affecting the pallet's transport when the first conveying roller 703 is used to transport the pallet.

[0059] Along the conveying direction of the conveying unit, there are sequentially distributed assembly unit, inflation unit, leak detection unit, pressure resistance test unit, and manufacturing supervision unit.

[0060] The tray is used to place the porcelain column circuit breaker, enabling the porcelain column circuit breaker to be moved between the shuttle car, the assembly unit, the inflation unit, the leak detection unit, the withstand voltage test unit, and the manufacturing supervision unit.

[0061] The final assembly unit includes an assembly platform located on one side of the conveyor rail, such as... Figure 3As shown in the schematic diagram, the assembly platform includes a platform body 201. The bottom of the platform body 201 is supported by several support legs. The support legs include upper support legs 202 and lower support legs 203 distributed vertically. The upper support legs 202 are hollow cuboids, and the lower support legs 203 are U-shaped. After the upper support legs 202 are inserted into the lower support legs 203, they are locked and fixed by a pair of bolts and nuts. There are a pair of through holes on the upper support legs 202 to accommodate bolts, and a pair of waist-shaped adjustment holes on the lower support legs 203 to accommodate bolts. The adjustment holes extend vertically. By cooperating with the waist-shaped adjustment holes, the relative position of the upper support legs 202 and the lower support legs 203 can be adjusted, thereby changing the length of the entire support leg.

[0062] A second conveyor roller group is provided on both sides of the platform body 201. The second conveyor roller group includes several second conveyor rollers 204 arranged in parallel. The two sides of the second conveyor rollers 204 are movably mounted on the platform body 201 through the cooperation of bearings and bearing seats. Each second conveyor roller 204 is synchronously rotated in the same direction by the cooperation of sprockets and chains. Any one of the second conveyor rollers 204 is driven to rotate by a motor installed on the platform body 201, which drives all the second conveyor rollers 204 to rotate synchronously. The two groups of second conveyor rollers have the same conveying direction. A sealing plate 205 is also provided between adjacent second conveyor rollers 204.

[0063] A pair of parallel airbag buffers 206 are also installed on the platform body 201 at the second conveyor roller group. Correspondingly, the length of the second conveyor roller 204 located at the airbag buffer 206 is shorter than the length of the second conveyor roller 204 at other locations.

[0064] A second plate 207 is also provided on the platform body 201 between the two sets of second conveyor rollers. The second plate 207 is a rectangular plate, and the height of the upper end surface of the second plate 207 is lower than the height of the top of the second conveyor roller 204.

[0065] The assembly platform is designed to support the pallet using the combined action of the second conveyor roller 204 and the second flat plate 207. This facilitates the movement of the pallet on the assembly platform and allows personnel to stand on the second flat plate 207 to operate the circuit breaker. The height of the second flat plate 207 is designed to be lower than the apex of the second conveyor roller 204 to avoid interference with its transport. The sealing plate 205 between the second conveyor rollers 204 eliminates gaps between adjacent rollers, preventing the pallet from jamming during transport. The airbag buffer 206 positions and secures the pallet after it has been transported to its designated location, preventing it from moving back and forth on the second conveyor rollers 204 and interfering with personnel operations.

[0066] On both sides of the platform body 201, an anti-tipping component is respectively provided. The anti-tipping component includes an anti-tipping plate 207, which is located above the second conveyor roller 204. A cuboid groove is also formed at the bottom end of the anti-tipping plate 207. The cuboid groove and the second conveyor roller 204 cooperate to form an anti-tipping cavity for limiting the pallet. The design of the anti-tipping component is to limit the pallet by the anti-tipping cavity formed by the anti-tipping plate 207 and the second conveyor roller 204, so as to prevent the pallet from tipping over when it is conveyed on the second conveyor roller.

[0067] Above the final assembly platform, there is also a gantry crane guide rail and a gantry crane.

[0068] The inflation unit includes an inflation platform disposed on one side of the conveying guide rail 101. The inflation platform and the final assembly platform are located on the same side of the conveying guide rail 101, and the structure of the inflation platform is the same as that of the final assembly platform, which will not be described in detail here.

[0069] The leak detection unit includes a leak detection chamber 401 located on one side of the conveyor rail 101. The leak detection chamber 401 and the assembly platform are located on the same side of the conveyor rail 101. The leak detection chamber 401 has a leak detection cavity and several partitions 402 that divide the leak detection cavity into multiple independent cavities. A leak detection platform is installed in each cavity of the leak detection chamber 401, and the structure of the leak detection platform is the same as that of the assembly platform, so it will not be described in detail here. The design of the leak detection chamber 401, through the partitions 402, divides one leak detection chamber 401 into multiple independent spaces, thereby enabling simultaneous leak detection of multiple porcelain-column circuit breakers. This is because the leak detection test itself takes much longer than the withstand voltage test; therefore, multiple leak detection positions are designed to match and improve detection efficiency.

[0070] On the other side of the conveyor rail 101 located at the leak detection chamber 401, an anomaly handling unit is also provided. The anomaly handling unit includes a handling bracket 403, which includes a bottom bracket and side brackets. Both the bottom bracket and the side brackets are hollow rectangular brackets. There are two side brackets, which are vertically connected to both sides of the bottom bracket, thus forming a U-shaped bracket for the entire handling bracket 403.

[0071] A top beam 404 is connected to the top of the processing bracket 403, and a processing platform 405 is installed on the processing bracket 403. The processing platform 405 is a U-shaped frame.

[0072] A third conveyor roller group is provided on each side of the processing platform 405. The third conveyor roller group includes several third conveyor rollers 406 arranged in parallel. The two sides of the third conveyor rollers 406 are movably mounted on the processing platform 405 through the cooperation of bearings and bearing seats. Each third conveyor roller 406 is synchronously rotated in the same direction by the cooperation of sprockets and chains. Any one of the third conveyor rollers 406 is driven to rotate by a motor installed on the processing platform 405, which drives all the third conveyor rollers 406 to rotate synchronously. The conveying direction of the two groups of third conveyor rollers is the same.

[0073] A third plate 407 is also provided on the processing platform 405 between the two sets of third conveyor rollers, and the height of the upper end surface of the third plate 407 is lower than the height of the top of the third conveyor roller 406.

[0074] A pair of lifting mechanisms are also provided between the processing platform 405 and the top crossbeam 404. The lifting mechanism includes a lifting bracket 408, which is a combined bracket composed of a horizontal bracket, a vertical bracket, and an inclined bracket. The horizontal bracket and the vertical bracket are connected in a figure-7 shape, and the inclined bracket is inclined between the horizontal bracket and the vertical bracket. The two sides of the inclined bracket are connected to the two ends of the horizontal bracket and the vertical bracket, respectively, so that the inclined bracket, the horizontal bracket, and the vertical bracket form a triangular bracket. This design utilizes the stable characteristics of a triangle to make the overall structural strength of the lifting bracket 408 higher, which is more conducive to the stable lifting of the porcelain column circuit breaker by the lifting bracket 408.

[0075] A lifting plate 409 is installed on the lifting bracket 408. The lifting plate 409 is a U-shaped plate, and the openings of the two lifting plates 409 are arranged opposite each other. The lifting bracket 408 is driven by the lifting mechanism to move up and down, thereby driving the lifting plate 409 to move up and down.

[0076] The lifting mechanism consists of: vertically arranged lifting guide rails 410 installed on both sides of the side support of the treatment bracket 403, with the lifting guide rails 410 extending vertically; a lifting slider 411 that cooperates with the lifting guide rails 410 installed on the lifting bracket 408; a vertically arranged lifting screw 412 installed on the treatment bracket 403, which is driven to rotate by a lifting motor installed on the treatment bracket 403; and a screw nut that cooperates with the lifting screw 412 installed on the lifting bracket 408. Under the drive of the lifting screw 412, the lifting bracket 408 moves up and down along the lifting guide rails 410, thereby driving the lifting plate 409 to move up and down.

[0077] The withstand voltage test unit includes a withstand voltage test chamber 501 spanning a conveyor rail 101. The section of the conveyor rail 101 inside the withstand voltage test chamber is an insulated rail. A withstand voltage test platform is installed in the withstand voltage test chamber 501. The structure of the withstand voltage test platform is the same as that of the assembly platform, so it will not be described in detail here. However, it should be noted that the support legs of the withstand voltage test platform are also insulated support legs. This design is to avoid grounding and conductivity during the withstand voltage test, which would affect the smooth progress of the withstand voltage test.

[0078] The supervision unit includes a pair of supervision platforms set on one side of the conveyor rail 101. The supervision platform and the final assembly platform are located on the same side of the conveyor rail 101. The structure of the supervision platform is the same as that of the final assembly platform, and will not be described in detail here.

[0079] On the other side of the supervision platform, the conveyor guide 101 is also equipped with a lowering unit. The lowering unit includes a lowering platform, a lifting device and a tilting machine. The structure of the lowering platform is the same as that of the final assembly platform, so it will not be described in detail here.

[0080] like Figures 5-8 As shown in the schematic diagram, the turning machine includes

[0081] The tilting frame 1 is a hollow rectangular frame structure composed of several horizontal bars, vertical bars and vertical rods connected together. The length of the tilting frame 1 is greater than the width and the height of the tilting frame 1. Several support legs 16 are installed at the bottom of the tilting frame 1.

[0082] A flipping platform 2 is horizontally mounted on a flipping frame 1. The flipping platform 2 is a rectangular support. One side of the flipping platform 2 is hinged to the flipping frame 1, and the other side of the flipping platform 2 is placed flat on the flipping frame 1. The flipping platform 2 is driven to flip by a flipping mechanism mounted on the flipping frame 1.

[0083] The tilting mechanism includes a pair of tilting cylinders 21 mounted side-by-side on the tilting frame 1. The bottom end of the tilting cylinder 21 is hinged to the tilting frame 1, and the top end of the tilting cylinder 21 is hinged to the tilting platform 2. The hinge point between the tilting cylinder 21 and the tilting platform 2 is located on the side closer to the hinge point between the tilting platform 2 and the tilting frame 1. The tilting cylinder 21 is tilted, with its tilt direction gradually increasing from bottom to top towards the side closer to the hinge point between the tilting platform 2 and the tilting frame 1. This tilted setting makes it easier for the tilting cylinder 21 to apply force and push the tilting platform 2 to tilt up and down. The design of the tilting mechanism, using the cooperation of a pair of tilting cylinders 21 to achieve the tilting of the tilting platform 2, makes the tilting platform 2 more stable during movement, and also reduces the load-bearing capacity of a single tilting cylinder 21. In addition, designing the hinge point between the tilting cylinder 21 and the tilting platform 2 on the side closer to the hinge point between the tilting platform 2 and the tilting frame 1 reduces the stroke requirement of the tilting cylinder 21, thus reducing the cost of the tilting cylinder 21.

[0084] A support base is installed on the tilting platform 2. The support base is located near the side where the tilting platform 2 is hinged to the tilting frame 1. The support base includes a support frame 3 and a support plate 31 installed on the support frame 3. The support frame 3 is vertically fixed on the upper surface of the tilting platform 2. The support frame 3 is made of L-shaped angle iron. There is a pair of support plates 31, which are distributed on both sides of the support frame 3 along the width direction of the tilting platform 2. The support plates 31 are L-shaped and the two support plates 31 are arranged opposite to each other. A limiting groove for accommodating the lower flange seat 15 is also opened on the adjacent side of the two support plates 31. The shape of the L-shaped support plate 31 itself and the limiting groove on the two support plates 31 work together to achieve limiting support on three different surfaces of the lower flange seat 15, ensuring the stable placement of the lower flange seat 15.

[0085] The clamping assembly is installed on the flipping platform 2. There are several clamping assemblies, which are distributed sequentially along the long axis of the flipping platform 2. The clamping assembly includes a pair of clamping plates 4 arranged side by side on both sides of the width of the flipping platform 2. The two clamping plates 4 are driven to move closer or further apart by a horizontal mechanism installed on the flipping platform 2.

[0086] The horizontal mechanism consists of two pairs of translation guide rails 41 installed on both sides of the tilting platform 2, each corresponding to one of the two clamping plates 4. These two translation guide rails 41 are arranged side-by-side along the long axis of the tilting platform 2 and extend along its width. At the bottom of each clamping plate 4, a translation slider 42 is installed, corresponding to one of the two translation guide rails 41. The clamping plates 4 are brought closer together or further apart by the engagement of gears 43 and racks mounted on the tilting platform 2. The horizontal mechanism is designed so that the translation of a single clamping plate 4 is achieved using the engagement of a pair of translation guide rails 41, making the translation movement of the clamping plate 4 more stable, avoiding deviations, and ensuring the clamping of large circuit breakers.

[0087] The engagement between the clamping plates 4 and the gears 43 and racks is as follows: A rack is mounted at the bottom of each of the two clamping plates 4, positioned between two translation guide rails 41. The racks extend along the width of the flipping platform 2, reaching the center of the platform and overlapping. A gear 43, meshing with both racks, is mounted at the center of the platform. The gears 43 are driven by a translation motor mounted on the platform 2, causing the two racks to move synchronously in opposite directions, thus moving the two clamping plates 4 closer together or further apart. This engagement of the clamping plates 4 with the gears 43 and racks utilizes two overlapping racks extending to the center of the flipping platform to engage with the gears 43. This driving method requires only one gear 43 and one motor to move the two clamping plates 4 closer together or further apart, reducing the number of transmission and driving components, simplifying the structure, and lowering energy consumption.

[0088] A clamping groove is formed on the inner wall of the clamping plate 4. The clamping groove is in the shape of an isosceles trapezoid, with the two sides of the clamping groove located on the upper and lower sides respectively. The shorter bottom of the clamping groove is located on the inner side of the clamping plate 4, and the longer bottom of the clamping groove is located on the outer side of the clamping plate 4, so that the entire clamping plate 4 forms a C-shaped structure. After the two clamping plates 4 are brought together, the clamping grooves on the two clamping plates 4 work together to form a clamping cavity for clamping the pole of the large circuit breaker.

[0089] Several auxiliary support platforms 5 are also installed on the tilting platform 2. The auxiliary support platforms 5 are located on the center line of the tilting platform 2, and each auxiliary support platform 5 is arranged sequentially along the long axis of the tilting platform. The bottom end of the auxiliary support platform 5 is mounted on the tilting platform 2 through an auxiliary bracket 51. A support groove is also opened on the upper surface of the auxiliary support platform 5. The support groove is in the shape of an isosceles trapezoid, and the length of the upper base of the support groove is longer than the length of the lower base of the support groove. The design of the auxiliary support platforms 5 on the tilting platform 2 is to provide auxiliary support for the large circuit breaker. On the other hand, it can also provide main support for the large circuit breaker after it is laid flat. This can reduce the clamping force of the clamping plate 4 on the large circuit breaker, or even eliminate the clamping force, thus avoiding damage to the pole column caused by prolonged clamping.

[0090] When flipping the pole, firstly, the flipping platform 2 flips upward under the drive of the two flipping cylinders 21, causing the flipping platform 2 to swing upward along the hinge point between the flipping platform 2 and the flipping frame 1 until the flipping platform 2 changes from a horizontal state to a vertical state. At the same time, each clamping plate 4 moves to both sides under the drive of the corresponding horizontal mechanism, so that the two clamping plates 4 in the same clamping assembly are in the open state. Then, the vertically placed large circuit breaker is hoisted onto the support platform 31 by a gantry crane. Each clamping assembly works, driving the two clamping plates 4 in the same clamping assembly to move closer to each other, using the two clamping plates 4 to clamp the pole of the large circuit breaker. The upper pole 12 and the lower pole 14 are clamped by different clamping assemblies respectively. After clamping, the flipping platform 2 flips downward under the drive of the two flipping cylinders 21, so that the flipping platform 2 changes from a vertical state to a horizontal state. After the flipping platform 2 is completely horizontal, the entire large circuit breaker is supported on each auxiliary support platform 5, thus completing the flipping of the large circuit breaker from a vertical state to a horizontal state.

[0091] Working Principle: When testing a porcelain column circuit breaker, firstly, at the assembly platform, with the assistance of a gantry crane, components such as the poles and operating mechanisms are installed on the base. Then, the assembled porcelain column circuit breaker is conveyed to a shuttle car by the second conveyor roller 204 on the assembly platform. The shuttle car moves the porcelain column circuit breaker to the inflation unit and then transfers it to the inflation platform. At the inflation platform, the porcelain column circuit breaker is inflated. After inflation, the porcelain column circuit breaker is moved from the inflation platform back to the shuttle car, which continues to move it to the leak detection unit. The shuttle car then transfers the porcelain column circuit breaker to the leak detection platform. A leak test is performed on the porcelain column circuit breaker in the leak detection room. If an abnormality is detected, the porcelain column circuit breaker is transferred from the leak detection platform back to the shuttle car. The circuit breaker is then transferred by a shuttle to the processing bracket 403, where it is handled by personnel. If no abnormalities are found, the shuttle transfers the porcelain column circuit breaker to the withstand voltage test unit and then to the withstand voltage test platform. The withstand voltage test is conducted on the porcelain column circuit breaker in the withstand voltage test chamber 501. After the withstand voltage test, the porcelain column circuit breaker is returned to the shuttle, which then moves it to the supervision unit and then to the construction platform. At the supervision platform, based on the previous test results, the test result labels are affixed to the corresponding porcelain column circuit breaker. The porcelain column circuit breaker is then transferred from the supervision platform back to the shuttle, and then from the shuttle to the offline platform. At the offline platform, the pole and base are separated, and then the pole is hoisted to the tilting machine using a lifting device. The tilting machine then lays the pole flat, completing the entire testing process.
