[0032] The staff starts the control module 43 according to the position of the steel structure beam. The control module 43 starts to drive the second hydraulic rod 431 to gradually extend and retract, and the second hydraulic rod 431 pushes the protective shell 442 to slide inside the lifting arm 41, and the driving component slides in the limiting slide groove 411. The movement of the telescopic arm 42 can change the distance of the lifting point, thereby adjusting the position of the hook 447. The length of the lifting beam is different, so the position of the lifting point is also different. The staff starts the first hydraulic rod 423, and the first hydraulic rod 423 gradually extends and retracts, and pushes the winding box 424 and the driving component to move inside the telescopic arm 42.

The staff drives through the motor and gear parts, and the staff adjusts the position of the winding box 424 according to the position of the lifting point, and facilitates the hook 447 to be positioned with the lifting point. The two ends of the beam are aligned to facilitate the same force on the lifting points. Then the staff starts the second motor 443, which starts and drives the second reducer 441 to work. The second reducer 441 drives the winding rod 445 to rotate, so that the winding rod 445 drives the traction rope 446 to gradually extend.

A counterweight block 32 is provided on the outer wall of the support beam 31, and a sliding hole 321 is provided in the middle of the counterweight block 32. The sliding hole 321 is slidably connected to the support beam 31, and a first motor 322 is fixedly connected to the inside of the top of the counterweight block 32.

The bottom end of the protective limit block 325 is slidingly connected to the rack 312. The internal rotation of the protective limit block 325 is connected to a rotating rod 326. The top end of the rotating rod 326 is transmission connected to the first reducer 324, and the bottom end of the rotating rod 326 is fixedly connected to a gear 327, which meshes with the rack 312.

[0035] When the steel structure beam is lifted, the first motor 322 is started, and the first motor 322 starts to drive the first rotating shaft 323 to rotate.

The rear oblique support rod 21 can support the rear of the support column 2 to prevent the counterweight block 32 from moving too much and causing the support column 2 to bend. The front oblique support rod 21 can support the lifting arm 41 to prevent the telescopic arm 42 from bending due to the force generated by the sliding of the lifting arm 41.

The staff starts the control module 43 according to the position of the steel structure beam, and the control module 43 starts to drive the second hydraulic rod 431 to gradually extend and retract, and the second hydraulic rod 431 is gradually extended and retracted. The pressure rod 431 pushes the protective shell 442 to slide inside the lifting arm 41, and the driving assembly slides in the limiting slide groove 411. The movement of the telescopic arm 42 can change the distance of the lifting point, thereby adjusting the position of the hook 447. The length of the lifting beam is different, so the position of the lifting point is also different. The staff starts the first hydraulic rod 423, the first hydraulic rod 423 gradually retracts and pushes the winding box 424 and the driving assembly to move inside the telescopic arm 42, and the staff adjusts the position of the winding box 424 according to the position of the lifting point, and makes it easy for the hook 447 to be aligned with the lifting point position, so that the lifting point is stressed. Similarly, the staff then starts the second motor 443, which starts to drive the second reducer 441 to work, and the second reducer 441 drives the winding rod 445 to rotate, so that the winding rod 445 drives the traction rope 446 to gradually extend, and then the staff hangs the hook 447 on both ends and the middle of the beam, and then starts the second motor 443, and the second motor 443 drives the second rotating shaft 444 to flip, so that the second reducer 441 works in the reverse direction, so that the winding rod 445 starts to wind up the traction rope 446, because the second motor 443 and the second reducer 441 are set at the same speed, The traction rope 446 rises synchronously, making the beam rise more stably, and the first motor 322 is started while lifting, and the first motor 322 starts to drive the first rotating shaft 323 to rotate, and the first rotating shaft 323 rotates to drive the first reducer 324 to work, and the first reducer 324 drives the rotating rod 326 to rotate, and the rotating rod 326 rotates to drive the gear 327 to rotate, and the gear 327 rotates to engage with the rack 312, and the force generated by the engagement makes the counterweight block 32 slide on the support beam 31.

The first reducer is fixedly connected to the counterweight block, and the first motor starts to drive the first rotating shaft to rotate, and the first rotating shaft drives the first reducer to work, thereby driving the gear to rotate to realize the movement of the counterweight block. The counterweight block slides on the support beam and moves according to the weight of the hoisted steel structure beam, thereby achieving a counterweight effect.

8. According to claim 1, a synchronous lifting frame for hoisting large-span steel structure beams in a photovoltaic glass all-oxygen kiln, Features: A protective limit block is fixedly connected to the side of the bottom end of the first reducer away from the first motor. The protective limit block passes through the top of the counterweight block and is fixedly connected to the counterweight block. The bottom end of the protective limit block is slidably connected to the rack. The protective limit block is located inside the first slide groove and limits the counterweight block. During the internal sliding of the counterweight block, the protective limit block can protect the rotating rod.

9. According to claim 1, a synchronous lifting frame for hoisting large-span steel structure beams in a photovoltaic glass all-oxygen furnace, Features: The protective limit block is internally rotatably connected to a rotating rod, the top end of the rotating rod is transmission-connected to the first reducer, the bottom end of the rotating rod is fixedly connected to a gear, the gear is meshed with the rack, the rotation of the first reducer drives the rotating rod to rotate, the rotation of the rotating rod drives the gear to rotate, and the rotation of the gear is meshed with the rack, and the force generated by the meshing causes the counterweight to slide on the support beam. Therefore, the staff drives the counterweight to the corresponding position on the support beam according to the weight of the steel structure beam, thereby increasing the overall stability.

10. A synchronous lifting frame for hoisting large-span steel structure beams in a photovoltaic glass all-oxygen furnace according to claim 1, Features: The support column is fixedly connected with side support rods on both sides, and the bottom ends of the side support rods are fixedly connected to the base. The support column is different from the side support rods in that the two sides are fixedly connected with oblique support rods. The bottom end of one oblique support rod is fixedly connected to the base, and the top end of the other oblique support rod is fixedly connected to the lifting arm. The support column is used for overall support, and the side support rods are used to support both sides of the support column to increase the stability of both sides. The rear oblique support rod can support the rear of the support column to prevent the support column from bending due to excessive movement of the counterweight block, and the front oblique support rod can support the lifting arm to prevent the telescopic arm from bending due to the force generated by the sliding of the telescopic arm in the lifting arm.
