Description

Technical Field

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In a substation, a herringbone column (frame column) is usually set up next to the transformer. The herringbone column is a support structure used to support and fix the conductors, insulator strings and other electrical accessories on the transformer. The herringbone column is usually designed in a V-shape or an inverted Y-shape, which can provide sufficient mechanical strength and stability to ensure that the transformer and its accessories will not be displaced due to vibration or external forces during operation. Since the frame column is generally set next to the transformer, when the transformer catches fire due to an emergency, it will affect the mechanical properties of the frame column, its bearing capacity will gradually decrease, and the supported power equipment and wires will be engulfed by the fire, causing greater economic losses. Therefore, it is necessary to perform performance tests on the frame column during actual installation.

[0004] However, the existing frame columns have the following deficiencies when testing: the existing testing method usually applies pressure to the herringbone column from top to bottom, but the herringbone column is usually subjected to lateral tensile force by cables, and the measurement accuracy is insufficient; the herringbone column structure is large, if the herringbone column is installed in advance and then the components of the test device are installed around the herringbone column, the testing process will be more troublesome, so a performance testing device for substation frame columns is proposed to solve the above problems.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-8 The present invention discloses a performance test device for a substation frame column, including a mobile platform 1, on which a positioning assembly is arranged, the positioning assembly is used to fix a frame column 9 located on the mobile platform 1, a furnace 6 is installed on one side of the mobile platform 1, the furnace 6 includes a furnace body 61 and a furnace door 62 slidably installed on the furnace body 61 near the side of the mobile platform 1, the furnace body 61 will burn inside when working, and when burning, the furnace door 62 needs to be closed to prevent adverse effects on the outside of the furnace body 61, the mobile platform 1 can drive the fixed frame column 9 to enter and exit the furnace 6 after the furnace door 62 is opened, the furnace 6 is used to heat the frame column 9 to be tested, and the above-mentioned furnace 6 belongs to the common knowledge in the field, so the specific structural composition and working principle thereof will not be described in detail in this article.

[0038] In one embodiment, the device further comprises a lifting assembly, which is arranged above the mobile platform 1 and is located on one side of the stove 6. The lifting assembly comprises columns 2 vertically installed on both sides of the mobile platform 1. A vertically arranged lifting module 3 is installed between the two columns 2. The lifting module 3 can drive the simulation test assembly 5 to move up and down, and it can be a linear module. A crossbeam 4 is installed at the moving end of the lifting module 3, and a simulation test assembly 5 is installed on the crossbeam 4. The simulation test assembly 5 comprises a winding component, and a pull rope 58 is wound on the winding component. The pull rope A hook 54 is provided at one end of 58 away from the winding component. When the frame column 9 moves into the interior of the furnace 6, its top will be hooked with the hook 54, and the hook 54 will be driven to leave the simulation test component 5. The lifting component can drive the simulation test component 5 to move up and down, and can make the simulation test component 5 rise and staggered with the frame column 9 passing from its bottom; it can also descend when the frame column 9 is located inside the furnace 6, cooperate with the winding component to make the pull rope 58 tilt downward and tighten the pull rope 58, so as to simulate the mechanical load applied by the cable to the top of the frame column 9.

[0039] In the specific implementation, the frame column 9 to be tested is lifted to the side close to the mobile platform 1 by the lifting device. When the frame column 9 gradually approaches the mobile platform 1, the positioning component will guide the frame column 9 to approach the moving end of the mobile platform 1 and fix it thereon. After the fixation is completed, the lifting device and the frame column 9 can be separated. Subsequently, the frame column 9 is driven to move to the side close to the furnace 6 by the mobile platform 1 until it enters the furnace 6. During this process, the frame column 9 will pass through the simulated test component 5 staggered therefrom, and at the same time, the plate-like structure on the top of the frame column 9 will also be hooked with the hook 54, and drive the hook 54 leaves the simulation test assembly 5, and the pull rope 58 is gradually stretched. When the frame column 9 is completely moved into the furnace 6 and stops, the simulation test assembly 5 is driven down to make the pull rope 58 tilt downward. This state is the same as the state of the cable lapped on the frame column 9 in actual conditions. At this time, the winding component is started to tighten the pull rope 58. In this state, the mechanical load (such as tension, pressure, etc.) applied by the cable to the top of the frame column 9 can be simulated. In combination with the combustion of the frame column 9 by the furnace 6, the actual performance of the frame column 9 in a burning state can be simulated very efficiently, realistically and accurately.

[0040] It should be noted that the simulation test component 5 is also equipped with a detection unit such as a tension sensor, and the furnace 6 is equipped with a temperature sensor, which can monitor the working status of the simulation test component 5 and the furnace 6 in real time, so as to more accurately know the performance of the frame column 9 under the corresponding state.

[0041] In one embodiment, the frame column 9 includes a column body 91 and two bases 92 installed at the bottom of the column 91; the mobile platform 1 includes a fixed seat, a bearing platform body 7 slidably arranged on the fixed seat, and a pushing component for pushing the bearing platform body 7 to slide back and forth on the fixed seat. The pushing component can be a hydraulic push rod. When the pushing component works, it can drive the bearing platform body 7 to enter and exit the furnace 6. The bearing platform body 7 includes a bearing platform plate 71, which is used to carry the frame column 9. The positioning assembly is arranged at the two bases 92 of the bearing platform plate 71 corresponding to the frame column 9. The positioning assembly is arranged at the two bases 92 of the frame column 9 corresponding to the frame column 9. The component includes a limit block, which is fixed on one side of the corresponding base 92 on the supporting platform 71, and a limit ring 72 is slidably arranged in the limit block, one side of the limit ring 72 is located outside the limit block, and one side of the limit ring 72 has a missing portion for the column 91 to pass through, and when the missing portion of the limit ring 72 is located in the limit block, the base 92 cannot be vertically moved out of the limit ring 72; a driving component 73 is also arranged in the supporting platform 71, which is used to drive the limit ring 72 to rotate so that the missing portion of the limit ring 72 is exposed from the limit block or rotated into the limit block.

[0042] In the specific implementation, in the initial state, the missing part of the limit ring 72 is located outside the limit block, and the frame column 9 can move into the limit ring 72 through the missing part. Subsequently, the drive assembly 73 can be used to drive each limit ring 72 to rotate to the missing part and move it into the limit block. At this time, the limit ring 72 surrounds and is fixed on the outside of the frame column 9 at the column foot, so that the frame column 9 can be fixed on the bearing platform 7; conversely, when the frame column 9 is tested, the control hoisting device is connected to the frame column 9 again, and each limit ring is driven to rotate to the missing part and move it into the limit block. The positioning ring 72 rotates to the missing part and moves to the outside of the limiting block. At this time, the frame column 9 can be lifted horizontally to make the column foot of the frame column 9 detach from the missing part of the limiting ring 72, so that the frame column 9 can be removed from the supporting platform 7 after the inspection. A bearing sleeve 77 is also installed on the limiting block. The bearing sleeve 77 is mounted on the limiting ring 72. The bearing sleeve 77 can enhance the bearing capacity of the limiting ring 72, so that the limiting ring 72 can further enhance the anti-collapse ability of the frame column 9 when limiting the frame column 9.

[0043] In one embodiment, two relatively distributed mounting grooves 74 are provided on the support platform 71 , and each mounting groove 74 is used to position a corresponding base 92 , and the bottom of the limiting ring 72 contacts the top of the base 92 .

[0044] With this design, when the positioning assembly guides the frame column 9 to approach the supporting platform 71, it will guide the two bases 92 at the bottom of the column 91 to be respectively snapped into the corresponding mounting grooves 74, and cooperate with the limiting ring 72 to fix the column 91 at the foot, so that the frame column 9 can be further stably fixed on the supporting platform 71, so as to improve the stability of the frame column 9 during detection and movement.

[0045] In one embodiment, each limiting ring 72 has an annular groove coaxially opened on its outer wall, and the driving assembly 73 includes an anti-slip plate 731 installed on the corresponding limiting ring 72 on the bearing platform 71, one side of the anti-slip plate 731 extends into the corresponding annular groove to rotate with the limiting ring 72, and two gear rods 732 are rotatably installed on the anti-slip plate 731, and the two gear rods 732 are respectively located on both sides of the corresponding limiting ring 72, and the gear rod 732 is composed of a rod body and a gear body arranged on the rod body. The limiting ring 72 is annularly distributed with teeth meshing with the gear body, and a first motor 735 is installed in the bearing platform 71, and the first motor 735 drives the two gear rods 732 to rotate synchronously through the transmission assembly.

[0046] In a specific implementation, the transmission assembly includes a bevel gear set 734 mounted on the rotating shaft of the first motor 735, the bevel gear set 734 is composed of two bevel gear bodies meshing with each other, the two bevel gear bodies are coaxially mounted on the rotating shaft of the first motor 735 and one of the gear rods 732, the first motor 735 is used to cooperate with the bevel gear set 734 to drive one of the gear rods 732 to rotate, a first transmission belt set 733 is provided on the two rod bodies, the first transmission belt set 733 is composed of two transmission wheels and a transmission belt arranged on the two transmission wheels, the two transmission wheels are coaxially arranged on the two rod bodies, the first transmission belt set 733 is used to drive the other gear rod 732 to rotate when one of the gear rods 732 rotates, and a second transmission belt set 736 is also provided at the corresponding gear rods 732 on the two anti-dropping plates 731, the second transmission belt set 736 has the same structure as the first transmission belt set 733, and is used to drive the other anti-dropping plate 73 when the gear rod 732 on one of the anti-dropping plates 731 rotates. The gear rods 732 on 1 rotate synchronously, and the anti-dropping plates 731 are respectively located in the corresponding annular grooves, which can make the limiting ring 72 very stable during rotation adjustment. When in use, the first motor 735 is started, and it cooperates with the bevel gear set 734 to drive one of the gear rods 732 to rotate. The rod bodies of the two corresponding gear rods 732 are provided with a first transmission belt set 733, and the setting of the first transmission belt set 733 can make the other gear rod 732 connected thereto rotate synchronously. This design can ensure that one of the above-mentioned two gear bodies can always be engaged with the limiting ring 72, and there will be no loss of transmission effect when the missing part rotates toward the gear body. Since the second transmission belt set 736 is provided, when the gear rod 732 on one of the anti-dropping plates 731 rotates, the second transmission belt set 736 can transmit and drive the gear rod 732 on the other anti-dropping plate 731 to rotate synchronously. Therefore, only one power source is needed to make all the gear rods 732 on the two anti-dropping plates 731 rotate synchronously.

[0047] In one embodiment, an entry slot is provided at the bottom of the furnace 6, a heat dissipation cavity 75 is provided inside the supporting platform 71, and the two side walls of the supporting platform 71 perpendicular to its own moving direction are open, and a filter plate 78 connected to the heat dissipation cavity 75 is embedded in the corresponding opening of the supporting platform 71, and a heat dissipation component 76 is provided in the corresponding heat dissipation cavity 75 of the supporting platform 71, and the air suction end and the air exhaust end of the heat dissipation component 76 are respectively facing the two filter plates 78, and the heat dissipation component 76 can discharge the heat inside the supporting platform 71 to the outside of the supporting platform 71. When the supporting platform 71 drives the frame column 9 to enter the furnace 6 and blocks the entry slot, the filter plate 78 on one side of the supporting platform 71 passes through the entry slot to the outside of the furnace 6, and the filter plate 78 on the other side of the supporting platform 71 is also located outside the furnace 6.

[0048] In a specific implementation, a heat dissipation port (not shown in the figure) is provided on the side wall of the mobile platform 1 close to the stove 6 for facilitating heat dissipation. When the supporting platform 71 moves to the lower side of the stove 6, it enters the entry groove, and the top wall of the supporting platform 71 blocks the bottom of the stove 6. The filter plates 78 on both sides of the supporting platform 71 are located on the outside of the stove 6. One of the filter plates 78 contacts the heat dissipation port on the corresponding side wall of the mobile platform 1, and the other filter plate 78 is located at the bottom of the stove door 62. When the stove 6 is working, heat will accumulate inside the supporting platform 71. At this time, the heat dissipation component 76 is started, and the air outside the device enters the heat dissipation cavity 75 from one of the filter plates 78 and is discharged from the other filter plate 78. The heat dissipation cavity 75 and the airflow channel formed at the open part are located at the bottom of the stove 6, which are staggered with the inside of the stove 6, so that the supporting platform body 7 will not be affected by internal overheating and the service life of the structure, and the setting of the filter plate 78 can prevent dust and other impurities outside the equipment from entering the heat dissipation cavity 75.

[0049] In one embodiment, the positioning assembly also includes a guide component 8, which includes a second motor 81 installed at the top center of the support platform 71, and a vertical electric push rod 82 is installed at the moving end of the second motor 81, and a guide frame 83 with an S-shaped appearance is installed horizontally at the moving end of the electric push rod 82. The second motor 81 is used to drive the electric push rod 82 and the guide frame 83 to rotate clockwise or counterclockwise by ninety degrees, and the second motor 81 is a brake motor, which stops working when it rotates ninety degrees. At this time, the brake circuit is started to lock the rotating shaft of the second motor 81, and the electric push rod 82 is used to drive the guide frame 83 to move up and down. The guide frame 83 rotates ninety degrees to hook on the outside of the frame column 9 and slide with the frame column 9 to guide the hoisted frame column 9 to move to the specified position of the support platform 71; wherein, the length of the guide frame 83 is less than the length of the bottom of the frame column 9 but greater than the length of the middle of the frame column 9.

[0050] In the specific implementation, in the initial state, the guide frame 83 does not contact the two column feet of the frame column 9. When the lifting device lifts the frame column 9 to the same height as its column feet and the guide frame 83, the guide frame 83 is controlled to rotate ninety degrees so that it can hook on the frame column 9. During this process, the frame column 9 will gradually move toward the top center of the load-bearing platform 71 as the guide frame 83 rotates. Then, the guide frame 83 is controlled to descend by the electric push rod 82, and the frame column 9 is descended to the base 92 and inserted into the installation groove 74. The device can effectively guide the frame column 9 suspended in the air to the center of the top of the load-bearing platform 71, thereby facilitating practical use.

[0051] In addition, the guide member 8 can be separated from the frame column 9 by performing the above-mentioned reverse operation, so the removal work of the frame column 9 after the test is completed will not be affected.

[0052] In one embodiment, the winding component includes a platform 51 connected to the crossbeam 4, a third motor 52 is installed on the platform 51, a winding shaft 53 is rotatably installed on the platform 51, the third motor 52 is used to drive the winding shaft 53 to rotate, the pull rope 58 is wound on the winding shaft 53, a guide platform 55 is installed at the bottom of the platform 51, the guide platform 55 is used to guide the hook 54 to move to the center of the bottom of the platform 51 when resetting, and a magnet 56 is also provided at the bottom of the platform 51, the magnet 56 is magnetically attracted to the hook 54, and the magnetic attraction force between the magnet 56 and the hook 54 is smaller than the thrust of the frame column 9 when the hook 54 is driven to move.

[0053] In a specific implementation, after the hook 54 is hooked with the top of the frame column 9, as the frame column 9 continues to move toward the side close to the stove 6, it drives the hook 54 to leave the bottom of the magnet 56. At this time, the pull rope 58 on the reel 53 is stretched. When the frame column 9 is completely moved into the stove 6, the simulation test assembly 5 can be controlled to descend. At this time, the pull rope 58 is inclined, and then the third motor 52 can be driven to start, the reel 53 rotates and reels the pull rope 58, and the stove 6 burns the frame column 9, so as to perform a performance test on the frame column 9. After the inspection of the frame column 9 is completed, it is necessary to control it to be moved out of the furnace 6. During the movement, the frame column 9 passes through the platform 51, and the hook 54 on its top will gradually move to the middle of the bottom of the platform 51 under the guidance of the guide platform 55. When the hook 54 continues to move to the bottom of the magnet 56, the magnet 56 will magnetically fix it. Since the magnetic attraction between the magnet 56 and the hook 54 is smaller than the thrust of the frame column 9 when driving the hook 54 to move, when the frame column 9 moves to the side close to the furnace 6, the hook 54 can be normally taken away from the bottom of the magnet 56.

[0054] In one embodiment, an anti-dropping component 57 is disposed on the hook 54 .

[0055] With such a design, the anti-detachment component 57 can clamp the top of the frame column 9 when the simulation test component 5 applies a mechanical load to the top of the frame column 9, thereby preventing the hook 54 from being detached from the frame column 9, and the anti-detachment component 57 will release the frame column 9 after the simulation test component 5 stops working, thereby not affecting subsequent use.

[0056] In one embodiment, the hook 54 is hollow inside, and a plurality of guide sleeves 575 are installed inside. The anti-slip assembly 57 includes two limit plates 571 rotatably installed on opposite sides of the hook 54. The opposite sides of the two limit plates 571 are installed with soft anti-skid layers 576, and the anti-skid layers 576 can be rubber layers with anti-skid patterns. The two sides of the hook 54 are rotatably installed with trigger blocks 572. The connection between each limit plate 571 and the trigger block 572 and the hook 54 is provided with a torsion spring for resetting. 4 is provided with a connecting rope 573, which is located in the guide sleeve 575. The two ends of the connecting rope 573 are respectively connected to the two trigger blocks 572. A ring 574 is provided on the sliding sleeve of the connecting rope 573. One end of the pull rope 58 extends into the hook 54 and is connected with the ring 574. When the pull rope 58 tightens the connecting rope 573, the connecting rope 573 can drive the trigger block 572 to rotate. A limiting groove 577 is provided inside the hook 54. An anti-dropping piece is installed on the pull rope 58, and the anti-dropping piece can be slidably arranged in the limiting groove 577.

[0057] In a specific implementation, when the trigger block 572 rotates, it can squeeze the limiting piece 571, so that the limiting piece 571 rotates synchronously to the outside of the hook 54 and clamps the top of the frame column 9. Before adjustment, the hook 54 is hooked on the top of the frame column 9. When the winding shaft 53 rotates and tightens the pull rope 58, the pull rope 58 first drives the connecting rope 573 to move to the side close to the winding shaft 53. At this time, each trigger block 572 rotates and squeezes the limiting piece 571 to rotate to the outside of the hook 54. Since the connecting rope 573 is movably connected to the pull rope 58 through the ring 574, when one of the limiting pieces 571 is connected When it touches the frame column 9 and cannot rotate, the connecting rope 573 can move in the ring 574. Therefore, continuous pulling of the pull rope 58 will cause the connecting rope 573 to continue to pull the other trigger block 572 to continue rotating until the two limit plates 571 clamp the top of the frame column 9. When the plate-like structure on the top of the frame column 9 is at a different distance from the two limit plates 571, the structure can still effectively position it. After positioning, the anti-slip sheet moves synchronously with the pull rope 58 and contacts the side wall of the corresponding limit groove 577 of the hook 54, thereby driving the hook 54 to move synchronously and perform measurement.
