Substation equipment is usually large and heavy. Manually moving it to a high place is not only difficult, but also poses great safety risks. The use of 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 to avoid dangerous situations such as shaking, tilting, or even falling of the equipment, thereby ensuring the safety and smooth progress of the equipment installation process.

The bottom of each of the two guide rails 201 is bolted to the top of the transfer platform 104, and the tops of the two sliders 207 are respectively fixedly installed at the bottom of the push plate 205 near the front surface and the rear surface.

[0024] In this embodiment, when in use, the push drive system 202, the push cylinder 203, the forward and reverse motor 302, the electric push rod 402, the laser ranging 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 drive system 202 are all existing mature technologies, and no further details are given here. The substation equipment is placed on the two guide rails 201, and one side of the substation equipment is in contact with the outer surface of the push plate 205, and the protection component 3 is started. With the cooperation of the push plate 205, the substation equipment is clamped and fixed, thereby improving the stability of the substation equipment during the subsequent lifting process.

With the cooperation of the lifting component 1 and the push component 2, the effect of automatic lifting and pushing is achieved, and there is no need for multiple people to cooperate in transporting the equipment, which reduces physical energy consumption and labor intensity, and does not affect the subsequent installation efficiency. It solves the problem that when the substation equipment is installed, after it is lifted to the target height by the hydraulic lifting and transporting equipment, it is necessary to manually push the substation equipment from the transport platform to the installation position, which requires high coordination of manual cooperation, consumes a lot of physical energy, has high labor intensity, and the operator is easily tired, which affects the installation efficiency.

A movable plate 314 is fixedly installed on the opposite side of the two protective frames 301, and a plurality of sliding rods 315 are fixedly installed on the bottom of the two movable plates 314. A sliding rail 316 is movably embedded inside the plurality of sliding rods 315, and a push-pull plate 317 is fixedly installed on the opposite side of the two movable plates 314. One end of the two rotating shafts 303 is movably penetrated to the outer surface of one side of the two protective frames 301, and the other ends of the two rotating shafts 303 are movably penetrated to the outer surface of the other side of the two protective frames 301.

[0026] In this embodiment, when the substation equipment is placed on the two guide rails 201, the outer surface of one side of the substation equipment contacts the outer surface of the push plate 205. The two forward and reverse motors 302 are started, and the two shafts 303 are driven to rotate by the rotation of the output ends of the two forward and reverse motors 302. At this time, the front shaft 303 rotates backward and the rear shaft 303 rotates forward, thereby driving the front protection rod 307 to rotate out of the first movable hole 105 and rotate toward the front surface of the substation equipment, and at the same time, the rear protection rod 307 rotates out of the first movable hole 105 and rotates toward the rear surface of the substation equipment.

The second bevel gear 311 drives the polygonal clamping rod 310 to rotate while driving the rotating rod 306 to rotate in the two mounting blocks 305, thereby driving the side protection rod 307 to rotate out of the second movable hole 106 and rotate toward the other side of the outer surface of the substation equipment, so that the front, rear and side protection rods 307 are together close to the substation equipment and contact it. With the cooperation of the push plate 205, the substation equipment is clamped and fixed on the top of the transport platform 104 to improve its stability and prevent shaking and instability during the subsequent lifting process, thereby achieving a protective 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 moved down, the two forward and reverse motors 302 are started again to drive the two rotating shafts 303 and the rotating rod 306 to rotate in the opposite direction, so that the protective rod 307 is rotated back to the first movable hole 105 and the second movable hole 106 again, loosening the clamping of the substation equipment without affecting the subsequent pushing and transporting work.

[0027] Embodiment 3: Figure 3-Figure 6 and Figure 10-12As shown, a pushing component 2 and a protective 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 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, a trapezoidal adjusting plate 403 is fixedly installed on one end of the electric push rod 402, three supporting rods 404 are movably embedded in the trapezoidal adjusting plate 403, the front and rear surfaces of the trapezoidal adjusting plate 403 are provided with adjusting grooves 405, the top and bottom surfaces of the two adjusting grooves 405 are provided with embedded grooves 406, sliding grooves 407 are arranged on both sides of the four embedded grooves 406, and 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, and pulleys 410 are movably sleeved on the outer surfaces of the four reinforcing rods 409. A detection plate 411 is fixedly installed on the edge of the opposite side of the two guide rails 201, and the bottom of the pushing plate 205 is close to the bottom of the pushing plate 205. A connecting block 412 is fixedly installed near one of the sliders 207, and a laser ranging sensor 413 is fixedly installed on the outer surface of one side of the connecting block 412. A protective box 414 is installed on the other side of the top of the conveying platform 104 by bolts. A communication module 415 and a PLC controller 416 are respectively arranged inside the protective box 414, and the communication module 415 and the PLC controller 416 are respectively installed on the top of the conveying platform 104 by bolts. One ends of the four reinforcement rods 409 are respectively movably embedded in the four embedded grooves 406, and the outer surfaces of the four pulleys 410 are respectively movably embedded in the four slide grooves 407. A square groove 108 is opened on the top of the conveying platform 104, and the bottom of the fixed block 401 is fixedly installed on the top of the conveying platform 104 near the square groove 108. The two ends of the three support rods 404 are respectively fixedly installed on both sides of the inside of the square groove 108, and the other ends of the two adjusting rods 408 are respectively fixedly installed on the opposite sides of the two push-pull plates 317.

[0028] In this embodiment, when in use, the laser distance sensor 413 is started, a laser beam is emitted to the detection plate 411, and the reflected laser beam is received to detect 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 push plate 205 and the detection plate 411 is detected. 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 set in advance inside the PLC controller 416. The PLC controller 416 identifies and compares the received distance data. When the distance data does not match the set width data, the PLC controller 416 will control the push drive system 202 to start, drive the push cylinder 203 and the push plate 205 to move, and drive the connecting block 412 and the laser distance sensor 413 to move, adjust the distance between the push plate 205 and the detection plate 411, and when the distance after the movement meets the set width data, the PLC controller 416 will shut down the push drive system 202. By adjusting the distance between the push plate 205 and the detection plate 411, the substation equipment of different widths can be adapted to achieve the effect of adjusting the width. The outer surfaces of both sides of the trapezoidal adjustment plate 403 are inclined, and the adjustment groove 405, the embedded groove 406 and the slide groove 407 are all inclined outwards. Fig.11 and Fig.12 As shown. Start the electric push rod 402 to push the trapezoidal adjustment plate 403 to move on the support rod 404, and at the same time make the pulley 410 rotate in the corresponding slide groove 407, the reinforcement rod 409 move in the embedded groove 406, and the adjustment rod 408 move in the adjustment groove 405. Since the adjustment groove 405, the embedded groove 406 and the slide groove 407 are all arranged to be inclined outward, when the pulley 410, the reinforcement rod 409 and the adjustment rod 408 move along the outward inclined track, they will be simultaneously subjected to 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, and under the limiting action of the slide rod 315 and the slide rail 316, the two protection frames 301 are pushed outward, thereby expanding the distance between the two protection frames 301, adapting to substation equipment of different lengths, thereby achieving the effect of adjusting the length, 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, and further drives the two limit sleeves 312 to move, thereby partially pulling the polygonal clamping rod 310 out of the polygonal clamping slot 309, which neither affects the distance adjustment of the protective frame 301 nor affects the clamping and fixing of the equipment by the subsequent three groups of protective rods 307.

[0029] The usage method and working principle of the present invention are as follows: start the laser ranging sensor 413, detect the distance between the push 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 set in advance inside the PLC controller 416. When the distance data does not match the set width data, the PLC controller 416 will control the push drive system 202 to start, drive the push cylinder 203 and the push plate 205 to move, and drive the connecting block 412 and the laser ranging sensor 413 to move, adjust the distance between the push plate 205 and the detection plate 411, and when the distance after the movement meets the set width data, the PLC controller 416 will turn off the push drive system 202. By adjusting the distance between the push plate 205 and the detection plate 411, it can adapt to substation equipment of different widths, thereby achieving the effect of adjusting the width. The adjustment groove 405, the embedded groove 406 and the slide groove 407 are all arranged to be inclined outward, such as Fig.11 and Fig.12The electric push rod 402 is started to push the trapezoidal adjustment plate 403 to move on the support rod 404, and at the same time, the pulley 410 rotates in the corresponding slide groove 407, the reinforcement rod 409 moves in the embedded groove 406, and the adjustment rod 408 moves in the adjustment groove 405, and is simultaneously subjected to 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, and under the limiting action of the slide rod 315 and the slide rail 316, the two protection frames 301 are pushed outward, thereby expanding the distance between the two protection 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 that the polygonal clamping rod 310 is partially pulled out from the polygonal clamping slot 309, which does not affect the distance adjustment of the protective frame 301, nor does it affect the clamping and fixing of the equipment by the subsequent three groups of protective rods 307. The substation equipment is placed on the two guide rails 201, and one side of the substation equipment is in contact with the outer surface of the push plate 205. The two forward and reverse motors 302 are started 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, thereby driving the front protective rod 307 to rotate out of the first movable hole 105 and rotate toward the front surface of the substation equipment. At the same time, the rear protective rod 307 rotates out of the first movable hole 105 and rotates toward the rear surface of the substation equipment. The two rotating shafts 303 rotate while driving the two first bevel gears 304 to rotate, and further drive the two second bevel gears 311 to rotate, the polygonal clamping rod 310 is meshed and connected with the polygonal clamping groove 309, and the second bevel gear 311 drives the polygonal clamping rod 310 to rotate while driving the rotating rod 306 to rotate in the two mounting blocks 305, thereby driving the side protection rod 307 to rotate out of the second movable hole 106 and rotate toward the other side of the outer surface of the substation equipment, so that the front, rear and side protection rods 307 are together close to the substation equipment and contact it, and with the cooperation of the push plate 205, the substation equipment is clamped and fixed on the top of the transport platform 104 to improve its stability. Start the hydraulic system 103, push the lifting mechanism 102 to expand upward, and push the transport platform 104, the push assembly 2, the protection assembly 3 and the adjustment assembly 4 to move upward together. When the substation equipment is lifted to the target height, close the hydraulic system 103 so that the height of the guide rail 201 is flush with the target height. Then the protection assembly 3 is started again to drive the two rotating shafts 303 and the rotating rod 306 to rotate in the opposite direction, so that the protection rod 307 rotates back to the first movable hole 105 and the second movable hole 106 again, and the clamping of the substation equipment is released.Start the two push cylinders 203 so that the piston rods of the two push cylinders 203 extend at the same time, and push the push plate 205 to move through the two mounting plates 204, further driving the substation equipment to move, and then start the push drive system 202 to continue to provide power so that the push assembly 2 continues to move as a whole. Under the action of the push assembly 2, the substation equipment is pushed from the top of the transport platform 104 to the installation position, and there is no need for multiple people to cooperate in transporting the equipment, which reduces physical exertion, reduces labor intensity, and does not affect the subsequent installation efficiency.

[0030] Among them, the lifting mechanism 102, the hydraulic system 103, the push drive system 202, the push cylinder 203, the forward and reverse motor 302, the electric push rod 402, the laser ranging sensor 413, the communication module 415, and the PLC controller 416 are all existing technologies, and their components and usage principles are all public technologies, which will not be explained in detail here.
