[0029] First, the steel structure to be lifted is placed in the clamping assembly 4, and the steel structure is lifted and placed in the designated working position through the control system 2 and the wire rope 3, thereby completing the lifting operation of the steel structure. The above are all existing technologies and no unnecessary elaboration is given.

A gantry rod 413 is slidably sleeved in the ring 407, a clamping rod 419 is fixedly connected in the gantry rod 413, a moving plate 412 is fixedly connected to the lower side of the moving ring 407, a first rack 415 is fixedly connected to the lower side of the moving plate 412, a rotating cylinder 427 is rotatably connected in the clamping plate 402, a first gear 430 is fixedly sleeved on the outer side of the rotating cylinder 427, the first gear 430 and the first rack 415 are meshed, two groups of rotating rods 428 are symmetrically fixedly connected to the outer side of the rotating cylinder 427, a clamping rod 429 is fixedly connected to the outer side of the two groups of rotating rods 428, and a clamping cylinder 406 is fixedly connected to the outer side of the clamping rod 429;

[0031] First, when the steel structure needs to be hoisted, the corresponding steel structure is placed between the two sets of clamping plates 402. At this time, under the action of its own gravity, the gantry rod 413 is located on the upper side of the threaded rod 403, and the clamping rod 419 is located in the threaded groove inside the threaded rod 403. At this time, the first electric push rod 404 is started, and the first electric push rod 404 drives the threaded rod 403 to move in the direction close to the first electric push rod 404. The threaded rod 403 drives the moving ring 407 to move through the clamping rod 419 and the gantry rod 413, and the moving ring 407 drives the fixed ring through the first spring 408 409 moves, the fixed ring 409 drives the clamping plate 402 to move towards the direction close to the first electric push rod 404 through the connecting rod. When the two clamping plates 402 and the steel structure are against each other, the two clamping plates 402 will be stuck by the steel structure and stop moving. However, at this time, the threaded rod 403 continues to move. The threaded rod 403 drives the moving ring 407 to move through the clamping rod 419 and the gantry rod 413. The moving ring 407 compresses the first spring 408, and the moving ring 407 moves relative to the clamping plate 402. The moving ring 407 drives the first rack 415 to move through the moving plate 412. Figure 7Based on the direction, the first rack 415 moving to the right will drive the first gear 430 to rotate counterclockwise, and the first gear 430 drives the rotating cylinder 427 to rotate counterclockwise. The rotating cylinder 427 drives the clamping cylinder 406 to rotate counterclockwise around the rotating cylinder 427 through the rotating rod 428 and the clamping rod 429 until the clamping cylinder 406 and the steel structure are against each other. At this time, the first electric push rod 404 is closed (the first electric push rod 404 has a self-locking function, and the device as a whole is in a stationary state), thereby completing the clamping and fixing operation of the steel structure.

[0032] Reference Figure 5 A plurality of card slots 417 are evenly formed on the lower side of the square rod 410, a fixing plate 411 is fixedly connected to the clamping plate 402, a plurality of card holes 418 are formed on the upper side of the fixing plate 411, and a card rod 419 is opposite to the card hole 418 and the card slot 417. After the clamping and fixing operation of the steel structure is completed, especially when the gantry rod 413 starts to move upward, the gantry rod 413 drives the card rod 419 to move upward, so that the card rod 419 passes through the card hole 418 and enters the card hole 418, thereby completing the stabilizing operation between the clamping plate 402 and the fixing frame 401, and improving the stability of the clamping effect.

[0033] like Figure 6 , Figure 8 , Fig. 9 A rotating assembly for controlling the rotation of the clamping cylinder 406 is installed in the clamping plate 402, and the rotating assembly includes a rotating ring 421 threadedly sleeved on the outside of the threaded rod 403, and the rotating ring 421 is rotatably connected to the fixed ring 409. An intermediate rod 422 is rotatably connected in the clamping plate 402, and a pulley assembly 420 is sleeved between the intermediate rod 422 and the rotating ring 421. A second gear 423 is fixedly sleeved on the outside of the intermediate rod 422. A control plate 424 is slidably sleeved up and down in the clamping plate 402, and a second spring 426 is fixedly connected between the control plate 424 and the clamping plate 402. A second electric push rod 425 is fixedly connected between the control plate 424 and the clamping plate, and a transmission rod 431 is rotatably connected to the side wall of the control plate 424. The outer side of the moving rod 431 is fixedly sleeved with a third gear 432, and the side wall of the control plate 424 is also rotatably connected to two guide rods 433, and the outer sides of the two guide rods 433 are fixedly sleeved with a fourth gear 434, and the fourth gear 434 and the third gear 432 are meshed. The outer sides of the two guide rods 433 are also fixedly sleeved with a first bevel gear 435, and the outer side of the rotating cylinder 427 is rotatably sleeved with two third bevel gears 437, and the outer side of the clamping rod 429 is fixedly sleeved with a second bevel gear 436, and the second bevel gear 436 and the third bevel gear 437 are meshed. The lower side of the gantry rod 413 is fixedly connected to the regulating plate 414, and the regulating plate 414 is located on the upper side of the control plate 424 and is fixedly connected to the control plate 424;

[0034] First, under normal circumstances, the second gear 423 and the third gear 432 are not in a meshing state. When the threaded rod 403 moves, since the threaded rod 403 and the rotating ring 421 are threadedly sleeved, and the rotating ring 421 and the fixed ring 409 are rotatably connected, the moving threaded rod 403 will drive the rotating ring 421 to rotate, and the rotating ring 421 will drive the intermediate rod 422 to rotate through the pulley assembly 420, and the intermediate rod 422 will drive the second gear 423 to rotate. After completing the clamping operation on the steel structure, especially putting the steel When the structure is transported to a suitable working position, when it is necessary to push the steel structure to move relative to the fixed frame 401, the second electric push rod 425 is started, and the second electric push rod 425 drives the control plate 424 to move upward. While the control plate 424 stretches the second spring 426, the control plate 424 drives the transmission rod 431 and the guide rod 433 to move upward until the second gear 423 and the third gear 432 are in meshing state. At this time, the first bevel gear 435 and the second bevel gear 436 are also in meshing state. During this process, the control board 424 drives the regulating board 414 to move upward, the regulating board 414 adjusts the gantry rod 413 to move upward, the gantry rod 413 drives the clamping rod 419 to move upward, and the clamping rod 419 moves out of the threaded groove outside the threaded rod 403. At this time, the first electric push rod 404 is started again, the first electric push rod 404 drives the threaded rod 403 to move, the threaded rod 403 drives the rotating ring 421 to rotate, the rotating ring 421 drives the intermediate rod 422 to rotate through the pulley assembly 420, and the intermediate rod 422 is driven by the second gear 42 The third gear 432 is driven to rotate, the third gear 432 drives the guide rod 433 to rotate through the fourth gear 434, the guide rod 433 drives the third bevel gear 437 to rotate through the first bevel gear 435, the third bevel gear 437 drives the second bevel gear 436 to rotate, the second bevel gear 436 drives the clamping rod 429 and the clamping cylinder 406 to rotate around the clamping rod 429, the clamping rod 429 and the steel structure are offset to form a thrust on the steel structure, and the steel structure can be moved as a whole relative to the fixed frame 401.

[0035] like Fig. 9 , Fig.10A detection assembly for detecting steel structure defects is installed on the outside of the clamping cylinder 406. The detection assembly includes an arc plate 416 sleeved on the outside of the clamping cylinder 406. The arc plate 416 is fixedly connected to the clamping rod 429 through a connecting plate 438. A sensor 439 is slidably sleeved in the arc plate 416. A limit plate 440 is fixedly connected to the lower side of the sensor 439. A trapezoidal rod 441 is fixedly connected to the side wall of the limit plate 440. The trapezoidal rod 441 penetrates the side wall of the rotating cylinder 427. The rotating cylinder 427 A third connecting rod 445 is slidably sleeved inside, one side of the third connecting rod 445 is fixedly connected to the first trapezoidal plate 442, the first trapezoidal plate 442 and the trapezoidal rod 441 are butted against each other, the other side of the third connecting rod 445 is fixedly connected to the third trapezoidal plate 446, the side wall of the control plate 424 is fixedly connected to two second connecting rods 443, the side of the two second connecting rods 443 away from the control plate 424 is fixedly connected to the second trapezoidal plate 444, the second trapezoidal plate 444 and the third trapezoidal plate 446 are butted against each other;

[0036] First, the sensor 439 is a pressure sensor 439, which is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. When the control board 424 moves upward, the control board 424 drives the second connecting rod 443 to move upward, and the second connecting rod 443 drives the second trapezoidal plate 444 to move upward. Fig.10 As a basis, since the third connecting rod 445 is sleeved in the rotating cylinder 427, under the limiting effect of the rotating cylinder 427, the third connecting rod 445 as a whole can only move left and right relative to the rotating cylinder 427. Therefore, when the second trapezoidal plate 444 moves upward, the second trapezoidal plate 444 and the third trapezoidal plate 446 abut against each other and drive the third trapezoidal plate 446 to move leftward, and the third trapezoidal plate 446 drives the first trapezoidal plate 442 to move leftward through the third connecting rod 445. Secondly, since the limiting plate 440 and the arc plate 416 are slidably connected up and down, the limiting plate 440 can only move up and down relative to the arc plate 416. Therefore, the first trapezoidal plate 444 that moves leftward Plate 442 and trapezoidal rod 441 abut against each other and drive trapezoidal rod 441 to move upward, trapezoidal rod 441 drives limit plate 440 to move upward, limit plate 440 drives sensor 439 to move upward, so that sensor 439 moves out from arc plate 416 and abuts against the steel structure. During the movement of the steel structure, sensor 439 always abuts against the steel structure and sends out corresponding electrical signals. The staff can determine based on the electrical signals. When the electrical signals are relatively stable, it means that the inner wall of the steel structure is in good condition. If the electrical signals change greatly, it means that the internal defects of the steel structure are large, thereby completing a simple detection operation on the inner wall of the steel structure.

[0037] The side walls of the trapezoidal rod 441, the first trapezoidal plate 442, the second trapezoidal plate 444, and the third trapezoidal plate 446 are all smoothly configured, and the friction force of the trapezoidal rod 441, the first trapezoidal plate 442, the second trapezoidal plate 444, and the third trapezoidal plate 446 can be basically ignored, thereby better completing the corresponding transmission operation.

[0038] During the use of the present invention, when it is necessary to perform a lifting operation on the steel structure, the corresponding steel structure is placed between the two sets of clamping plates 402. At this time, under the self-gravity and the self-locking effect of the second electric push rod 425, the gantry rod 413 is located on the upper side of the threaded rod 403, and the clamping rod 419 is located in the threaded groove inside the threaded rod 403. At this time, the first electric push rod 404 is started, and the first electric push rod 404 drives the threaded rod 403 to move in the direction close to the first electric push rod 404. The threaded rod 403 drives the moving ring 407 to move through the clamping rod 419 and the gantry rod 413, and the moving ring 407 passes through the first The spring 408 drives the fixed ring 409 to move, and the fixed ring 409 drives the clamping plate 402 to move toward the first electric push rod 404 through the connecting rod. When the two clamping plates 402 and the steel structure are against each other, the two clamping plates 402 will be stuck by the steel structure and stop moving. However, the threaded rod 403 continues to move at this time. The threaded rod 403 drives the moving ring 407 to move through the clamping rod 419 and the gantry rod 413. The moving ring 407 compresses the first spring 408, and the moving ring 407 moves relative to the clamping plate 402. The moving ring 407 drives the first rack 415 to move through the moving plate 412. Figure 7Based on the direction of rotation, the first rack 415 moving to the right will drive the first gear 430 to rotate counterclockwise, and the first gear 430 drives the rotating cylinder 427 to rotate counterclockwise, and the rotating cylinder 427 drives the clamping cylinder 406 to rotate counterclockwise around the rotating cylinder 427 through the rotating rod 428 and the clamping rod 429 until the clamping cylinder 406 and the steel structure are against each other. At this time, the first electric push rod 404 is closed (the first electric push rod 404 has a self-locking function, and the device as a whole is in a stationary state), thereby completing the clamping and fixing operation of the steel structure, and at this time, the second electric push rod 425 is started, and the second electric push rod 425 drives the control board 424 to move upward, and the control board 424 stretches the second spring 426. At the same time, the control plate 424 drives the transmission rod 431 and the guide rod 433 to move upward until the second gear 423 and the third gear 432 are in meshing state. At this time, the first bevel gear 435 and the second bevel gear 436 are also in meshing state. In this process, the control plate 424 drives the regulating plate 414 to move upward, and the regulating plate 414 mobilizes the gantry rod 413 to move upward. The gantry rod 413 drives the clamping rod 419 to move upward, and the clamping rod 419 moves out of the threaded groove outside the threaded rod 403, so that the clamping rod 419 passes through the clamping hole 418 and enters the clamping hole 418, thereby completing the stabilization operation between the clamping plate 402 and the fixed frame 401, and improving the stability of the clamping effect;

[0039] By controlling the control system 2 and the steel wire rope 3, the steel structure is lifted and placed at the designated working position, thereby completing the lifting operation of the steel structure. After the lifting is completed, if the steel structure needs to be directly removed, the above reverse operation can be repeated. If the steel structure needs to be moved, the first electric push rod 404 is started again, the first electric push rod 404 drives the threaded rod 403 to move, the threaded rod 403 drives the rotating ring 421 to rotate, the rotating ring 421 drives the intermediate rod 422 to rotate through the pulley assembly 420, and the intermediate rod 422 drives the intermediate rod 422 to rotate through the second The gear 423 drives the third gear 432 to rotate, the third gear 432 drives the guide rod 433 to rotate through the fourth gear 434, the guide rod 433 drives the third bevel gear 437 to rotate through the first bevel gear 435, the third bevel gear 437 drives the second bevel gear 436 to rotate, the second bevel gear 436 drives the clamping rod 429 and the clamping cylinder 406 to rotate around the clamping rod 429, the clamping rod 429 and the steel structure resist each other to form a thrust on the steel structure, thereby enabling the steel structure to move as a whole relative to the fixed frame 401;

[0040] In the above working process, when the control plate 424 moves upward, the control plate 424 drives the second connecting rod 443 to move upward, and the second connecting rod 443 drives the second trapezoidal plate 444 to move upward. Fig.10As a basis, since the third connecting rod 445 is sleeved in the rotating cylinder 427, under the limiting effect of the rotating cylinder 427, the third connecting rod 445 as a whole can only move left and right relative to the rotating cylinder 427. Therefore, when the second trapezoidal plate 44 moves upward, the second trapezoidal plate 444 and the third trapezoidal plate 446 abut against each other and drive the third trapezoidal plate 446 to move left, and the third trapezoidal plate 446 drives the first trapezoidal plate 442 to move left through the third connecting rod 445. Secondly, since the limiting plate 440 and the arc plate 416 are slidably connected up and down, the limiting plate 440 can only move up and down relative to the arc plate 416. Therefore, the first trapezoidal plate moving leftward 442 is against the trapezoidal rod 441 and drives the trapezoidal rod 441 to move upward, the trapezoidal rod 441 drives the limit plate 440 to move upward, the limit plate 440 drives the sensor 439 to move upward, so that the sensor 439 moves out from the arc plate 416 and is against the steel structure. During the movement of the steel structure, the sensor 439 is always against the steel structure and sends out a corresponding electrical signal. The staff can judge based on the emitted electrical signal. When the emitted electrical signal is relatively stable, it means that the inner wall of the steel structure is in good condition. If the emitted electrical signal changes greatly, it means that the internal defects of the steel structure are large, thereby completing a simple detection operation on the inner wall of the steel structure.
