[0028] An auxiliary hoisting device for a substation GIS device, including a mounting rod 1, a hoisting assembly 2 is arranged at the top of the mounting rod 1, and a bottom assembly 3 is arranged at the bottom of the mounting rod 1. The hoisting assembly 2 includes a hydraulic cylinder 201 at the top of the mounting rod 1. The bottom of the hydraulic cylinder 201 is fixedly connected with a driving rod 202. The driving rod 202 penetrates through the mounting rod 1 and extends to the bottom of the mounting rod 1. The driving rod 202 is slidably connected with the mounting rod 1. The bottom of the driving rod 202 is fixedly connected with a rectangular plate 203. The bottom of the rectangular plate 203 is fixedly connected with a mounting plate 204. A groove 205 is opened at the bottom of the mounting plate 204. A motor 206 is installed on the side of the mounting plate 204. The output end of the motor 206 is fixedly connected with a bidirectional lead screw 207. The bidirectional lead screw 207 penetrates through the mounting plate 204 and extends into the groove 205. The bidirectional lead screw 207 is rotatably connected with the mounting plate 204. A rectangular block 208 is threadedly connected to the outer surface of the bidirectional lead screw 207. The bottom of the rectangular block 208 is fixedly connected with a limiting clamp 209. Four stabilizing blocks 304 are provided, and the four stabilizing blocks 304 are respectively located at the top corners of the support plate 4.

[0029] Among them, the two rectangular blocks 208 move relative to or away from each other in the groove 205 of the mounting plate 204, thereby adjusting the distance between the limiting clamps 209 to adapt to GIS devices of different sizes.

[0030] In this embodiment, the bottom assembly 3 includes a support plate 4 at the bottom of the mounting rod 1. A side plate 301 is fixedly connected to the side of the support plate 4. A fixing rod 302 is arranged at the top of the side plate 301. The fixing rod 302 penetrates through the side plate 301 and extends to the bottom of the side plate 301. The fixing rod 302 is threadedly connected with the side plate 301. Installation rings 211 and wire boxes 210 are respectively fixedly connected to both sides of the rectangular plate 203. The installation ring 211 and the wire box 210 are opposite in position. A safety rope 212 is arranged at the bottom of the wire box 210 through a fixer 213. The end of the safety rope 212 is fixedly connected with a buckle. The buckle extends into the installation ring 211 and is buckled with the installation ring 211. An installation slot 303 is opened at the top of the support plate 4. A stabilizing block 304 is clamped in the installation slot 303. A support cylinder 6 is fixedly connected to the top of the support plate 4. The bottom of the mounting rod 1 extends into the support cylinder 6 and is slidably connected with the support cylinder 6. A plug rod 8 is inserted into the side of the support cylinder 6. The mounting rod 1 is L-shaped. A reinforcing plate 7 is fixedly connected to the side of the mounting rod 1. Four moving wheels 5 are movably connected to the bottom of the support plate 4. The four moving wheels 5 are respectively located at the bottom corners of the support plate 4.

[0031] Among them, the cooperation between the installation slot 303 and the stabilizing block 304 increases the stability of the device and prevents shaking during the hoisting process.

[0032] Workflow of the present invention: When the substation GIS equipment auxiliary hoisting equipment designed by this solution is in operation, first check whether the device is in normal use to ensure that all components are intact and functioning properly. Subsequently, place the support plate 4 at the bottom of the substation GIS equipment. Through the flexible movement of the moving wheels 5, adjust the equipment to the required hoisting position. Start the motor 206, which drives the bidirectional lead screw 207 to rotate, causing the two rectangular blocks 208 to move relative to or away from each other within the grooves 205 of the mounting plate 204, thereby adjusting the distance between the limit clips 209 to accommodate GIS equipment of different sizes. The limit clips 209 tightly grip the equipment. The operator can perform secondary fixation on the equipment through the safety rope 212 and the fixator 213 in the wire box 211 to ensure that it does not slip during hoisting. Then, the hydraulic cylinder 201 starts to work, pushing the drive rod 202 to extend, driving the rectangular plate 203 and the entire hoisting assembly to rise, thus achieving the hoisting of the GIS equipment off the ground. During this process, the bottom assembly 3 plays a key role. The side plate 301 is firmly connected to the support plate 4 through the fixing rod 302. The cooperation of the installation slot 303 and the stabilizing block 304 increases the stability of the device, preventing it from shaking during hoisting. At the same time, the design of the reinforcing plate 7 and the insertion rod 8 further enhances the stability of the device, ensuring the safe progress of the hoisting operation.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
