Substation equipment is usually large in volume and heavy in weight. Manually carrying it to a high place is not only extremely difficult but also poses great safety risks. Using a lifting and handling device can easily lift the equipment to the required height, and during the lifting process, the lifting and handling device can maintain the stability of the equipment, avoiding dangerous situations such as the equipment shaking, tilting, or even falling, thus ensuring the safety and smooth progress of the equipment installation process.

[0017] A using method of a lifting handling device for substation equipment installation includes the following steps:

[0018] S1. Start the laser distance sensor to detect the distance between the pushing plate and the detection plate, and transmit the data to the PLC controller for identification and comparison. When the distance data does not match the set width data, the PLC controller controls the pushing drive system to start, drives the connecting block and the laser distance sensor to move, and adjusts the distance between the pushing plate and the detection plate. When the moved distance conforms to the set width data, the PLC controller will turn off the pushing drive system;

[0019] S2. Start the electric push rod to move the trapezoidal adjusting plate, causing the pulley, reinforcing rod, and adjusting rod to move along an outwardly inclined trajectory. At the same time, they will be subjected to an outward thrust, thereby pushing the push-pull plate and the moving plate outward. Under the limiting effect of the sliding rod and the slide rail, the two protective frames are pushed outward to increase the distance between the two protective frames;

[0020] S3. Place the device on the two guide rails and contact the pushing plate. Start the two forward and reverse motors to drive the two rotating shafts and the two first bevel gears to rotate. Under the cooperation of the multi-angle clamping rod and the multi-angle clamping groove, drive the rotating rod to rotate, causing the front, rear, and side protective rods to rotate out and approach the substation equipment and contact it. With the cooperation of the pushing plate, the substation equipment is clamped and fixed on the top of the handling platform;

[0021] S4. Start the hydraulic system to push the lifting mechanism to expand upward and push the handling platform, the pushing component, the protective component, and the adjusting component to move upward together. When the substation equipment is lifted to the target height, turn off the hydraulic system and start the protective component again to drive the two rotating shafts and the rotating rod to rotate in the reverse direction, causing the protective rods to reset and release the clamping of the substation equipment;

[0022] S5. Start the two pushing oil cylinders. Through the extension of the piston rods, push the mounting plate and the pushing plate to move, further pushing the substation equipment to move. Then start the pushing drive system to continue providing power to make the whole pushing component continue to move, thereby realizing the pushing of the substation equipment and pushing it from the top of the handling platform to the installation position.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. When the present invention is used, start the two pushing oil cylinders, so that the piston rods of the two pushing oil cylinders extend simultaneously. Push the pushing plate to move through the two mounting plates, further driving the substation equipment to move. Then start the pushing drive system to continue providing power to make the whole pushing component continue to move. Under the action of the pushing component, the pushing of the substation equipment is realized, and it is pushed from the top of the handling platform to the installation position. With the cooperation of the lifting component and the pushing component, the effect of automatic lifting and pushing is achieved, eliminating the need for multiple people to cooperate in handling the equipment, reducing physical consumption, lowering labor intensity, and not affecting the subsequent installation efficiency.

[0025] 2. When the present invention is used, when the substation equipment is placed on the two guide rails and contacts the pushing plate. Start the two forward and reverse motors to drive the two rotating shafts and the two first bevel gears to rotate. Under the cooperation of the multi-angle clamping rod and the multi-angle clamping groove, drive the rotating rod to rotate, causing the front, rear, and side protective rods to rotate out and approach the substation equipment and contact it. With the cooperation of the pushing plate, the substation equipment is clamped and fixed on the top of the handling platform, improving its stability, thereby achieving the protective effect.

[0026] 3. When the present invention is in use, the laser distance sensor is activated to detect the distance between the pushing plate and the detection plate, and the data is transmitted to the PLC controller for identification and comparison. When the distance data does not match the set width data, the PLC controller controls the pushing drive system to start, driving the connecting block and the laser distance sensor to move, adjusting the distance between the pushing plate and the detection plate. When the moved distance conforms to the set width data, the PLC controller will turn off the pushing drive system, adjusting the distance between the pushing plate and the detection plate to adapt to substation equipment of different widths, thereby achieving the effect of width adjustment.

[0027] 4. When the present invention is in use, the electric push rod is activated to push the trapezoidal adjusting plate to move, causing the pulley, the reinforcing rod, and the adjusting rod to move along an outwardly inclined trajectory. At the same time, an outward thrust will be received, thereby pushing the push-pull plate and the moving plate to move outward. Under the limiting action of the sliding rod and the sliding rail, the two protective frames are pushed to move outward, expanding the distance between the two protective frames to adapt to substation equipment of different lengths, thereby achieving the effect of length adjustment, facilitating the placement of equipment of different sizes, and improving flexibility and applicability.

[0044] In this embodiment, during use, the push driving system 202, the push cylinder 203, the forward and reverse motor 302, the electric push rod 402, the laser distance sensor 413, the communication module 415 and the PLC controller 416 are electrically connected. Among them, the lifting mechanism 102, the hydraulic system 103 and the push driving system 202 are all existing mature technologies, and will not be elaborated here. Place the substation equipment on the two guide rails 201, and make one side of the substation equipment contact the outer surface of the push plate 205. Start the protection component 3, and with the cooperation of the push plate 205, clamp and fix the substation equipment to improve the stability of the substation equipment during subsequent lifting.

Under the action of the push component 2, the substation equipment is pushed and moved from the top of the handling platform 104 to the installation position. With the cooperation of the lifting component 1 and the push component 2, the effect of automatic lifting and pushing is achieved, which does not require multiple people to cooperate in handling the equipment, reduces physical consumption, reduces labor intensity, does not affect the subsequent installation efficiency, and solves the problem that when installing substation equipment, after lifting it to the target height by a hydraulic lifting handling device, it is necessary to manually push the substation equipment from the handling platform to the installation position, which requires high coordination of manual cooperation, consumes a lot of physical strength, has a large labor intensity, and the operator is easily fatigued, affecting the installation efficiency.

[0045] Embodiment 2: As Figures 3 - 10As shown in the figure, a pushing component 2 and a protection component 3 are arranged on the top of the lifting component 1, and an adjusting component 4 is arranged at the center of the top of the lifting component 1. The protection component 3 includes two protection frames 301. Positive and negative motors 302 are fixedly installed on the tops of the two protection frames 301. Output ends of the two positive and negative motors 302 are fixedly installed with rotating shafts 303. First bevel gears 304 are fixedly installed at one ends of the two rotating shafts 303. Two mounting blocks 305 are fixedly installed at one side of the top of the handling table 104. Rotating rods 306 are movably embedded in the two mounting blocks 305. A plurality of protection rods 307 are fixedly installed on the outer surfaces of the rotating rods 306 and the two rotating shafts 303. Rubber sleeves 308 are fixedly connected to one ends of the plurality of protection rods 307. Multi-angle clamping grooves 309 are formed at both ends of the rotating rod 306. Multi-angle clamping rods 310 are movably embedded in the two multi-angle clamping grooves 309. Second bevel gears 311 are fixedly installed at one ends of the two multi-angle clamping rods 310. Limit sleeves 312 are fixedly installed on the outer surfaces of the two multi-angle clamping rods 310. Sheathing plates 313 are movably sleeved on the outer surfaces of the two limit sleeves 312. Moving plates 314 are fixedly installed on opposite sides of the two protection frames 301. A plurality of sliding rods 315 are fixedly installed at the bottoms of the two moving plates 314. Slide rails 316 are movably embedded in the plurality of sliding rods 315. Push-pull plates 317 are fixedly installed on opposite sides of the two moving plates 314. One ends of the two rotating shafts 303 respectively penetrate through the outer surfaces of one sides of the two protection frames 301, and the other ends of the two rotating shafts 303 respectively penetrate through the outer surfaces of the other sides of the two protection frames 301.

Outer surfaces of one sides of the two sheathing plates 313 are respectively fixedly installed at edges of opposite sides of the two protection frames 301.

[0046] In this embodiment, during use, after the substation equipment is centered and placed on the two guide rails 201, the outer surface of one side of the substation equipment contacts the outer surface of the pushing plate 205. Start the two forward and reverse motors 302. The rotation of the output ends of the two forward and reverse motors 302 drives the two rotating shafts 303 to rotate. At this time, the front rotating shaft 303 rotates backward, and the rear rotating shaft 303 rotates forward, thereby driving the front guard bar 307 to rotate out from the first movable hole 105 and rotate towards the front surface direction of the substation equipment. At the same time, the rear guard bar 307 rotates out from the first movable hole 105 and rotates towards the rear surface direction of the substation equipment.

The multi-angle clamping rod 310 is meshed and connected with the multi-angle clamping groove 309. While the second bevel gear 311 drives the multi-angle clamping rod 310 to rotate, it drives the rotating rod 306 to rotate in the two mounting blocks 305, thereby driving the side guard bar 307 to rotate out from the second movable hole 106 and rotate towards the outer surface direction of the other side of the substation equipment, so that the front, rear, and side guard bars 307 move closer to the substation equipment and contact it. With the cooperation of the pushing plate 205, the substation equipment is clamped and fixed on the top of the handling platform 104, improving its stability and preventing it from shaking and being unstable during the subsequent lifting process, thereby achieving the protection effect. Under the action of the rubber sleeve 308, the tightness of the clamping and fixing is improved. When the substation equipment is lifted to the target height and needs to be carried down, start the two forward and reverse motors 302 again, drive the two rotating shafts 303 and the rotating rod 306 to rotate in the reverse direction, so that the guard bar 307 rotates back into the first movable hole 105 and the second movable hole 106 again, releasing the clamping of the substation equipment and not affecting the subsequent pushing and carrying work.

[0047] Embodiment 3: As Figures 3 - 6 and Figures 10 - 12As shown in the figure, a pushing component 2 and a protection component 3 are arranged at the top of the lifting component 1, and an adjusting component 4 is arranged at the center of the top of the lifting component 1. The adjusting component 4 includes a fixed block 401. An electric push rod 402 is fixedly installed on the outer surface of one side of the fixed block 401. One end of the electric push rod 402 is fixedly installed with a trapezoidal adjusting plate 403. Three support rods 404 are movably embedded in the trapezoidal adjusting plate 403. Adjusting grooves 405 are formed on the front surface and the rear surface of the trapezoidal adjusting plate 403. Inner embedding grooves 406 are formed on the top surface and the bottom surface of the two adjusting grooves 405. Sliding grooves 407 are formed on both sides of the inner parts of the four inner embedding grooves 406. Adjusting rods 408 are movably embedded in the two adjusting grooves 405. Two reinforcing rods 409 are fixedly installed on the outer surfaces of the two adjusting rods 408. Pulley 410 are movably sleeved on the outer surfaces of the four reinforcing rods 409. A detection plate 411 is fixedly installed at the edge of the opposite side of the two guide rails 201. A connecting block 412 is fixedly installed at the bottom of the pushing plate 205 near one of the sliders 207. A laser distance sensor 413 is fixedly installed on the outer surface of one side of the connecting block 412. A protection box 414 is installed on the other side of the top of the handling platform 104 by bolts. A communication module 415 and a PLC controller 416 are respectively arranged inside the protection box 414. The communication module 415 and the PLC controller 416 are respectively installed on the top of the handling platform 104 by bolts. One ends of the four reinforcing rods 409 are respectively movably embedded in the four inner embedding grooves 406. The outer surfaces of the four pulleys 410 are respectively movably embedded in the four sliding grooves 407. A square groove 108 is formed on the top of the handling platform 104. The bottom of the fixed block 401 is fixedly installed on the top of the handling platform 104 near the square groove 108. Both ends of the three support rods 404 are respectively fixedly installed on both sides inside the square groove 108. The other ends of the two adjusting rods 408 are respectively fixedly installed on the opposite sides of the two push-pull plates 317.

[0048] In this embodiment, during use, the laser distance sensor 413 is activated to emit a laser beam onto the detection plate 411 and receive the reflected laser beam, thereby detecting the distance between the laser distance sensor 413 and the detection plate 411, that is, the distance between the outer surface of one side of the pushing plate 205 and the detection plate 411. After the laser distance sensor 413 detects the distance data, it will transmit the data to the PLC controller 416 in the form of an electrical signal. The width data of the substation equipment is pre-set inside the PLC controller 416. The PLC controller 416 identifies and compares based on the received distance data. When the distance data does not match the set width data, the PLC controller 416 will control the pushing drive system 202 to start, drive the pushing oil cylinder 203 and the pushing plate 205 to move, and drive the connecting block 412 and the laser distance sensor 413 to move, adjusting the distance between the pushing plate 205 and the detection plate 411. When the moved distance conforms to the set width data, the PLC controller 416 will turn off the pushing drive system 202. By adjusting the distance between the pushing plate 205 and the detection plate 411, it adapts to substation equipment of different widths, thereby achieving the effect of width adjustment. The outer surfaces on both sides of the trapezoidal adjustment plate 403 are inclined, and the adjustment groove 405, the embedded groove 406, and the sliding groove 407 are all inclined outward, as Figure 11 and Figure 12 shown. The electric push rod 402 is activated to push the trapezoidal adjustment plate 403 to move on the support rod 404. At the same time, the pulley 410 rotates in the corresponding sliding groove 407, the reinforcing rod 409 moves in the embedded groove 406, and the adjusting rod 408 moves in the adjustment groove 405. Since the adjustment groove 405, the embedded groove 406, and the sliding groove 407 are all inclined outward, when the pulley 410, the reinforcing rod 409, and the adjusting rod 408 move along the outward-inclined trajectory, they will simultaneously receive an outward thrust, thereby generating an outward thrust on the push-pull plate 317, causing it to move outward in the corresponding moving hole 206, further pushing the moving plate 314 to move. Under the limiting action of the sliding rod 315 and the sliding rail 316, the two protective frames 301 are pushed to move outward, thereby expanding the distance between the two protective frames 301, adapting to substation equipment of different lengths, and thus achieving the effect of length adjustment, facilitating the placement of equipment of different sizes, and improving flexibility and applicability. When the protective frame 301 moves, it drives the two sleeve plates 313 to move, further driving the two limit sleeves 312 to move, thereby pulling out a part of the multi-angle clamping rod 310 from the multi-angle clamping groove 309, which neither affects the distance adjustment of the protective frame 301 nor affects the subsequent clamping and fixing of the equipment by the three groups of protective rods 307.

[0049] The usage method and working principle of the present invention are as follows: Start the laser distance sensor 413 to detect the distance between the pushing plate 205 and the detection plate 411, and transmit the data to the PLC controller 416 for identification and comparison. The width data of the substation equipment is preset inside the PLC controller 416. When the distance data does not match the set width data, the PLC controller 416 will control the start of the pushing drive system 202, drive the pushing oil cylinder 203 and the pushing plate 205 to move, and drive the connecting block 412 and the laser distance sensor 413 to move, so as to adjust the distance between the pushing plate 205 and the detection plate 411. When the moved distance conforms to the set width data, the PLC controller 416 will turn off the pushing drive system 202. By adjusting the distance between the pushing plate 205 and the detection plate 411, it can adapt to substation equipment with different widths, thus achieving the effect of width adjustment. The adjustment groove 405, the embedded groove 406 and the sliding groove 407 are all inclined outward, such as Figure 11 and Figure 12As shown. Start the electric push rod 402 to push the trapezoidal adjusting plate 403 to move on the support rod 404. At the same time, make the pulley 410 rotate in the corresponding chute 407, the reinforcing rod 409 move in the embedded groove 406, and the adjusting rod 408 move in the adjusting groove 405. At the same time, it is subjected to an outward thrust, so as to generate an outward thrust on the push-pull plate 317, making it move outward in the corresponding moving hole 206, further pushing the moving plate 314 to move. Under the limiting action of the sliding rod 315 and the slide rail 316, push the two protective frames 301 to move outward, so as to expand the distance between the two protective frames 301 to adapt to substation equipment of different lengths. When the protective frame 301 moves, it drives the two sleeve plates 313 to move, and further drives the two limit sleeves 312 to move, so as to pull out a part of the multi-angle clamping rod 310 from the multi-angle clamping groove 309, which neither affects the distance adjustment of the protective frame 301 nor affects the subsequent clamping and fixing of the equipment by the three groups of protective rods 307. Place the substation equipment on the two guide rails 201 and make one side of the substation equipment contact the outer surface of the pushing plate 205. Start the two forward and reverse motors 302 to drive the two rotating shafts 303 to rotate. At this time, the front rotating shaft 303 rotates backward, and the rear rotating shaft 303 rotates forward, so as to drive the front protective rod 307 to rotate out from the first movable hole 105 and rotate towards the front surface direction of the substation equipment. At the same time, the rear protective rod 307 rotates out from the first movable hole 105 and rotates towards the rear surface direction of the substation equipment. When the two rotating shafts 303 rotate, they drive the two first bevel gears 304 to rotate, and further drive the two second bevel gears 311 to rotate. The multi-angle clamping rod 310 is meshed with the multi-angle clamping groove 309. When the second bevel gear 311 drives the multi-angle clamping rod 310 to rotate, it drives the rotating rod 306 to rotate in the two mounting blocks 305, so as to drive the side protective rod 307 to rotate out from the second movable hole 106 and rotate towards the outer surface direction of the other side of the substation equipment, so that the front, rear and side protective rods 307 move towards the substation equipment together and contact it. With the cooperation of the pushing plate 205, the substation equipment is clamped and fixed on the top of the handling platform 104 to improve its stability. Start the hydraulic system 103 to push the lifting mechanism 102 to expand upward and push the handling platform 104, the pushing component 2, the protective component 3 and the adjusting component 4 to move upward together. When the substation equipment is lifted to the target height, turn off the hydraulic system 103 so that the height of the guide rail 201 is flush with the target height. Then start the protective component 3 again to drive the two rotating shafts 303 and the rotating rod 306 to rotate in the reverse direction, so that the protective rod 307 rotates back into the first movable hole 105 and the second movable hole 106 again, and releases the clamping of the substation equipment.Start two push cylinders 203 so that the piston rods of the two push cylinders 203 extend simultaneously. Push the push plate 205 to move through the two mounting plates 204, and further drive the substation equipment to move. Then start the push drive system 202 to continue providing power to make the whole push assembly 2 continue to move. Under the action of the push assembly 2, the pushing of the substation equipment is realized, and it is pushed from the top of the handling platform 104 to the installation position. It does not require multiple people to cooperate in handling the equipment, reduces physical exertion, lowers the labor intensity, and does not affect the subsequent installation efficiency.
