[0002] As a place for centralized voltage conversion, a substation includes a variety of power equipment, such as switches and transformers. The voltage is converted through the joint action of switches, transformers and other power equipment, thereby achieving long-distance power while reducing power consumption. Therefore, ensuring the working state and performance of the power equipment in the substation is good is an important part of realizing the function of the substation. Therefore, it is necessary to detect the status of the power equipment in the substation on a daily basis. Moreover, due to the heavy weight of the power equipment, the power equipment needs to be fixed during the detection process to maintain a stable state, so as to facilitate detection.

The input end of the lower bevel gear set 406 is rotatably mounted on the right-angle frame 401, and the right-angle frame 401 is fixedly mounted on the mounting plate 103. The push cylinder 402 is fixedly mounted on the right-angle frame 401, and the protruding end of the push cylinder 402 is fixedly connected to the T-plate, and the T-plate is slidably mounted on the right-angle frame 401, and a motor 403 is fixedly mounted on the T-plate. The output shaft of the motor 403 forms a belt transmission with one end of the connecting belt assembly 404, and the other end of the connecting belt assembly 404 forms a belt transmission with the sliding rod 405. The sliding rod 405 is rotatably mounted on the T-plate, and a small pulley is fixedly mounted on the end of the sliding rod 405 close to the connecting belt assembly 404. When the threaded rod 105 is rotated, the push cylinder 402 is extended, and the T-plate and the sliding rod 405 are pushed toward the side of the steering belt 108, so that the small pulley and the steering belt 108 form a pulley match; when the lower bevel gear set 406 is rotated, the push cylinder 402 is contracted, and the T-plate and the sliding rod 405 are pulled toward the side close to the lower bevel gear set 406, so that the sliding rod 405 is inserted into the input end of the lower bevel gear set 406.

[0042] Working principle: Move the entire device to the position of the electrical equipment to be tested through the roller under the chassis 101, start the pushing electric cylinder 402, and extend the protruding end of the pushing electric cylinder 402 to push the T-plate to the side away from the right-angle frame 401, so that the small pulley on the sliding rod 405 forms a pulley match with the steering belt 108. At this time, start the motor 403, and drive the sliding rod 405 and the small pulley on the sliding rod 405 to rotate through the connecting belt assembly 404, and drive the steering belt 108 to rotate through the small pulley, so that the threaded rod 105 on both sides of the steering belt 108 rotates. In this way, when the threaded rod 105 rotates, the bottom plate 104 that is threadedly matched with the threaded rod 105 will slide along the inside of the mounting plate 103 to the side close to the small cylindrical gear 106. At this time, the middle groove in front of the mounting plate 103 is left empty, surrounding the equipment to be tested.

[0043] After the equipment is surrounded, the telescopic cylinder 216 is started, and the driving rod 1 219 and the driving rod 2 220 are respectively inserted into the first and second rotating wheels above by contracting the extended end of the telescopic cylinder 216, and the transmission motor 214 is started. The output shaft of the transmission motor 214 drives the transmission belt 215 to rotate, and the driving rod 1 219 and the driving rod 220 that form the pulley with the transmission belt 215 rotate, so that the first and second rotating wheels will rotate, and at the same time drive the upper belt drive assembly 210 and the lower belt drive assembly 213 that form the pulley to rotate, so that the upper and lower ends of the upper belt drive assembly 210 and the lower belt drive assembly 213 that cooperate with each other can rotate. The plate belt assembly 1 208 and the upper plate belt assembly 2 209 as well as the lower plate belt assembly 1 211 and the lower plate belt assembly 2 212 rotate together, so that the upper plate spiral rod 1 204 and the upper plate spiral rod 2 205, the lower plate spiral rod 1 206 and the lower plate spiral rod 2 207 can be driven to rotate. Since the upper plate spiral rod 1 204, the upper plate spiral rod 2 205, the lower plate spiral rod 1 206 and the lower plate spiral rod 2 207 are respectively threaded with the upper arc plate 202 and the lower arc plate 203, the function at this time is to adjust the height of the upper arc plate 202 and the lower arc plate 203 according to the height of the equipment to be tested, so as to better fix the electrical equipment to be tested. Since both the driving rod 1 219 and the driving rod 2 220 are provided with two splines, and the splines on the driving rod 1 219 and the driving rod 2 220 are located in the same horizontal plane except for the top end, the other two splines are not in the same horizontal plane, that is, except for the top spline, when the second spline on the driving rod 1 219 is at the same horizontal position as that on the driving rod 2 220, the corresponding position on the driving rod 2 220 is not provided with a spline. In this way, according to actual working needs, when only the first rotating wheel or the second rotating wheel needs to rotate alone, the telescopic cylinder 216 can be contracted to different lengths to adjust whether the spline is inserted into the first rotating wheel or the second rotating wheel. Among the two wheels, the movement of the first wheel and the second wheel can be controlled separately, so as to independently adjust the height of the upper arc plate 202 and the lower arc plate 203. Because neither the driving rod 1 219 nor the driving rod 2 220 can rotate as long as the part without the spline is inserted, so if the first wheel and the second wheel need to rotate at the same time, the splines at the upper ends of the driving rod 1 219 and the driving rod 2 220 are inserted at the same time. If they need to move separately, continue to push the driving rod 1 219 and the driving rod 2 220. In this way, there will always be one of the first wheel and the second wheel without the spline, and it will not be able to rotate.

[0044] After the positions of the upper arc plate 202 and the lower arc plate 203 are adjusted, the clamping motor 301 is started to drive the clamping belt component 1 302 to rotate, and the clamping belt component 2 303 is driven to rotate through the clamping belt component 1 302. At this time, the clamping small belt component 304 rotates together with the clamping belt component 2 303, and the driving gear 305 fixedly connected to the output end of the clamping small belt component 304 will rotate, and the upper driving gear 305 drives the lower driving gear 305 to rotate together through the telescopic connecting column 307, thereby driving the sliding rack 306 at the same time to push the clamping plate 308 to the middle, clamping the electrical equipment to be tested.

[0045] At the same time, the pushing electric cylinder 402 contracts, causing the sliding rod 405 to be inserted into the input end of the lower bevel gear set 406. At this time, when the motor 403 rotates, it will drive the connecting belt assembly 404 and the sliding rod 405 to rotate the lower bevel gear set 406, and drive the upper bevel gear set 408 to rotate through the sliding connecting rod 407. The transmission shaft 410 connected to the output end of the upper bevel gear set 408 rotates, and the upper connecting belt 411 forming a belt drive with the transmission shaft 410 drives the screw 412 and the intermediate bevel gear set 414 to rotate. The intermediate bevel gear set 414 drives another intermediate bevel gear set 414 to rotate through the intermediate connecting column 415. In this way, the upper and lower screws 412 will rotate, thereby pushing the upper clamping plate 413 to the side close to the power equipment to clamp the power equipment. After the equipment is clamped, the transmission motor 214 restarts, driving the upper arc plate 202 and the lower arc plate 203 to move upward, lifting the clamped power equipment, and then pushing the electric cylinder 402 out, so that the small pulley forms a pulley match with the steering belt 108 again, and the connecting belt assembly 404 is reversed, so that the bottom plate 104 can be sent back to the initial position through the threaded rod 105, and at this time the bottom plate 104 is at the bottom of the power equipment. The purpose of this is to lift the power equipment to prevent it from falling, and then the inspector can conduct inspection.
