[0002] The Chinese name of GIS equipment is "gas-insulated metal-enclosed switchgear". In high-voltage, extra-high-voltage and ultra-high-voltage power grids, GIS equipment consists of circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, lightning arresters, busbars, connectors and outgoing line terminals, etc. These devices or components are all enclosed in a metal-earthed shell, and a certain pressure of SF6 insulating gas is filled inside. GIS equipment is widely used because of its compact structure, small floor area, high operation reliability, less maintenance workload and flexible configuration.

[0003] Some large GIS equipment needs to be spliced and constructed by dividing it into multiple small modular GIS equipment units. At present, no special jacking points are designed for each GIS equipment unit, and the rectangular frames are all of the direct landing type. When handling each GIS equipment unit, usually a slightly larger gap needs to be found between the bottom beam of the equipment frame and the foundation first, a crowbar is inserted into the gap, and it is manually pried many times to expand the gap to about 5 cm; then a claw-type hydraulic jack is placed, and the equipment is jacked up to 10 cm through the operation of the rocker, and then a row of frame rollers or a handling tank truck is placed at the bottom, and it is manually pushed and pulled or towed by a winch to the installation position. The handling process is relatively long, and the labor intensity of workers is large, and the safety risk is relatively high. Summary of the Invention

[0018] 3. For a GIS device installation and handling device provided by the present invention, the set adjusting plate can drive the movable plate to move along the slideway through the connecting rod, changing the position and angle of the movable plate. Then, with the cooperation of the auxiliary hydraulic cylinder, the angle and position of the push-pull hydraulic cylinder can be adjusted flexibly, so that the push-pull hydraulic cylinder can not only push the GIS device unit to tilt, but also pull the rope through the hook to assist the baffle to drive the GIS device unit to move onto the loading plate, while maintaining the stability of the GIS device unit and preventing the GIS device unit from tipping over during the loading process.

[0019] 4. The GIS equipment installation and handling device provided by the present invention can conveniently handle the directly landed GIS equipment unit through the action of the loading component and the auxiliary component.

A plurality of avoidance grooves 111 are spaced apart on the side of the support frame 11 close to the loading plate 21, and the connecting block 231 and the connecting plate 215 are both located in the corresponding avoidance grooves 111. The angle of the loading plate 21 is adjusted by the tilting hydraulic cylinder 23, so as to facilitate loading and unloading of the GIS equipment unit 4.

[0036] Furthermore, a receiving hole 131 is provided through the middle of the vertical plate 13, a lifting screw rod 141 is rotatably provided in the middle of the receiving hole 131, the lifting screw rod 141 is vertically provided, a receiving frame 22 is slidably provided in the receiving hole 131, a loading hydraulic cylinder 221 is provided in the receiving frame 22, a convex plate 224 is fixedly provided on the upper side of the receiving frame 22 close to the loading plate 21, the convex plate 224 is threadedly connected with the lifting screw rod 141, a lifting motor 14 is provided on the upper surface of the vertical plate 13, the output shaft of the lifting motor 14 is fixedly connected with the lifting screw rod 141, and slide grooves 132 are provided at positions on both sides of the receiving hole 131 of the vertical plate 13, and sliders 223 are fixedly provided on both sides of the convex plate 224, and the sliders 223 are slidably connected with the corresponding slide grooves 132. The movable receiving frame 22 can drive the loading hydraulic cylinder 221 and the baffle plate 222 to move up and down, which can not only pull the GIS equipment unit 4 onto the loading plate 21, but also limit the GIS equipment unit 4 during transportation.

[0037] Further, a movable plate 33 is slidably arranged above the support frame 11.

The arranged auxiliary hydraulic cylinders 35 can adjust the angle of the push-pull hydraulic cylinder 34. Cooperating with the movable plate 33, the orientation of the push-pull hydraulic cylinder 34 can be flexibly adjusted, so that the push-pull hydraulic cylinder 34 can not only push the GIS equipment unit 4 to tilt, but also pull the GIS equipment unit 4 through the rope 41 to prevent it from tipping over during the loading process.

[0038] Further, a plurality of groups of rollers 213 are rotatably arranged at intervals on the upper surface of the loading plate 21. The surface material of the rollers 213 is rubber. A plurality of support air bags 214 are arranged between adjacent two groups of rollers 213. When the support air bags 214 are not inflated, the height of their upper surfaces is lower than the height of the rollers 213 exposed above the upper surface of the loading plate 21. The support air bags 214 are in contact with or separated from the lower surface of the GIS equipment unit 4. After the support air bags 214 are inflated, they can lift the GIS equipment unit 4, playing a supporting role and a shock-absorbing role, preventing the internal components of the GIS equipment unit 4 from being damaged due to bumps during the handling process. When the support air bags 214 support the GIS equipment unit 4, the bottom of the GIS equipment unit 4 is separated from the rollers 213. Preferably, in order to ensure the stability of the whole device when loading the GIS equipment unit 4, hydraulic cylinders can be added around the support assembly 1 and made to contact the ground during loading to ensure the stability of the support assembly 1.

[0039] Further, an adjusting plate 31 is slidably arranged between the support frame 11 and the movable plate 33. Two fixing plates 16 are arranged at intervals in the vertical direction at one end of the vertical plate 13 away from the baffle 222. A positioning lead screw 151 is rotatably arranged between the two fixing plates 16. The two ends of the adjusting plate 31 are threadedly connected to the corresponding positioning lead screws 151. A positioning motor 15 is arranged at the upper end on the side of the vertical plate 13 away from the baffle 222.

A connecting rod 32 is rotatably arranged in the groove 312, and the other end of the connecting rod 32 is rotatably connected to the corresponding receiving plate 332.

[0041] Further, on the upper part of the surfaces of the two vertical plates 13 close to each other, sliding grooves 133 are provided. The sliding grooves 133 include two straight sliding grooves perpendicular to each other and an arc-shaped sliding groove. The two straight sliding grooves are connected through the arc-shaped sliding groove.

At both ends of the movable plate 33, vertical rods 37 are fixedly provided. On the surfaces of the two vertical rods 37 away from each other, two connecting columns 371 are arranged at intervals. The connecting columns 371 are inserted into the corresponding sliding grooves 133 and are slidably connected to the sliding grooves 133. When the movable plate 33 is at the initial position of the sliding groove 133, that is, the two connecting columns 371 of the vertical rod 37 are both in the vertical straight sliding groove, the vertical rod 37 is in a vertical state. As the adjusting plate 31 moves upward, the vertical rod 37 will change from a vertical state to an inclined state. When the two connecting columns 371 of the vertical rod 37 are both in the horizontal straight sliding groove, the vertical rod 37 is in a horizontal state.

[0042] Further, at the end of the piston rod of the push-pull hydraulic cylinder 34, a support block 341 is fixedly connected. On the side wall of the support block 341, a hook 3411 is fixedly provided. The hook 3411 is connected or separated from the rope 41. On the side of the support block 341 away from the push-pull hydraulic cylinder 34, an abutting block 36 is slidably arranged. On the side of the abutting block 36 close to the push-pull hydraulic cylinder 34, a connecting frame 361 is fixedly provided. On the side of the support block 341 away from the push-pull hydraulic cylinder 34, an installation groove 3412 is provided. The connecting frame 361 is inserted into the installation groove 3412 and is slidably connected to the installation groove 3412. A spring 3413 is arranged between the bottom of the connecting frame 361 and the bottom of the installation groove 3412. On the side of the connecting frame 361 away from the push-pull hydraulic cylinder 34, a rubber block 362 is fixedly provided. The rubber block 362 abuts against or separates from the upper part of the GIS equipment unit 4. The provided adjusting plate 31 can drive the movable plate 33 to move along the sliding groove 133 through the connecting rod 32, change the position and angle of the movable plate 33, and then through the cooperation of the auxiliary hydraulic cylinder 35, flexibly adjust the angle and position of the push-pull hydraulic cylinder 34, so that the push-pull hydraulic cylinder 34 can not only push the GIS equipment unit 4 to tilt, but also pull the rope 41 through the hook 3411 to assist the baffle 222 to drive the GIS equipment unit 4 to move onto the loading plate 21, and at the same time maintain the stability of the GIS equipment unit 4 to prevent the GIS equipment unit 4 from tipping over during the loading process.

[0043] When a GIS equipment installation and handling device is in use, two ropes 41 are pre-tied to the upper pipeline of the GIS equipment unit 4 to be handled. That is, the GIS equipment unit 4 can be pulled through the ropes 41. The loading hydraulic cylinder 221 is started to extend the piston rod of the loading hydraulic cylinder 221 to the maximum distance. At the same time, the lifting motor 14 is started. The output shaft of the lifting motor 14 rotates to drive the lifting lead screw 141 to rotate. The receiving frame 22 threadedly connected to the lifting lead screw 141 drives the loading hydraulic cylinder 221 and the baffle 222 to move upward. When the receiving frame 22 moves up to the top of the receiving hole 131, the lifting motor 14 is turned off. The driving device is moved to the GIS equipment unit 4, and the device is moved so that the GIS equipment unit 4 passes through the gap between the baffle 222 and the vertical plate 13. At this time, the lifting motor 14 is reversed, and the receiving frame 22 drives the baffle 222 to descend until the lower surface of the baffle 222 abuts against the ground, and then the lifting motor 14 is turned off. The piston rod of the loading hydraulic cylinder 221 is retracted until the bottom of the offset groove 2223 of the baffle 222 abuts against the bottom of the GIS equipment unit 4. At this time, the positioning motor 15 is started. The output shaft of the positioning motor 15 drives the positioning lead screw 151 to rotate. The adjusting plate 31 threadedly connected to the positioning lead screw 151 moves upward, drives the movable plate 33 to move upward through the connecting rod 32. The movable plate 33 moves along the slideway 133 through the connecting column 371, gradually changing from a vertical state to an inclined state or even a horizontal state. At the same time, the auxiliary hydraulic cylinder 35 is started to adjust the angle of the push-pull hydraulic cylinder 34 so that the abutting block 36 at the end of the push-pull hydraulic cylinder 34 faces the upper part of the GIS equipment unit 4. After the adjustment is completed, the positioning motor 15 is turned off, and the push-pull hydraulic cylinder 34 is started to make the rubber block 362 abut against the upper part of the GIS equipment unit 4 and push the GIS equipment unit 4 to make it tilt at a small angle. The tilt angle of the bottom plate of the GIS equipment unit 4 is less than 15°. At this time, the tilt hydraulic cylinder 23 is started, and the piston rod of the tilt hydraulic cylinder 23 is retracted to pull the loading plate 21 to rotate downward at the end close to the GIS equipment unit 4 until the tilt angle of the loading plate 21 is the same as the tilt angle of the bottom plate of the GIS equipment unit 4;

[0044] Restart the device to move it in the direction of the GIS equipment unit 4. At the same time, the pistons of the loading hydraulic cylinder 221 and the push-pull hydraulic cylinder 34 retract cooperatively. After the lower surface of the bottom plate of the GIS equipment unit 4 contacts the roller 213 on the loading plate 21, the device stops moving and abuts and locks with the ground through other hydraulic cylinders. Connect the rope 41 on the upper part of the GIS equipment unit 4 to the hook 3411 on the support block 341. Retract the piston rod of the push-pull hydraulic cylinder 34 to pull the upper part of the GIS equipment unit 4 to move inward toward the vertical plate 13. At the same time, drive the piston rod of the loading hydraulic cylinder 221 to retract, so that the abutting plate 2222 pushes the GIS equipment unit 4 to move onto the loading plate 21, preventing the GIS equipment unit 4 from tipping over when moving onto the loading plate 21. At the same time, the positioning motor 15 and the auxiliary hydraulic cylinder 35 move correspondingly, adjusting the position of the push-pull hydraulic cylinder 34 while making the push-pull hydraulic cylinder 34 pull the rope 41 to move. After most of the bottom plate of the GIS equipment unit 4 contacts the roller 213 on the loading plate 21, start the tilting hydraulic cylinder 23, and the piston rod of the tilting hydraulic cylinder 23 extends to make the loading plate 21 return to the horizontal state. After the GIS equipment unit 4 completely enters the loading plate 21, inflate the support airbag 214. After the support airbag 214 bulges, it supports the GIS equipment unit 4. Start the lifting motor 14 to move the baffle 222 upward to play a limiting role for the GIS equipment unit 4.
