[0007] By adopting the above technical solution, when it is necessary to hoist the steel on the ground, the lifting block can be driven to rise and fall in the vertical direction by using the lifting platform to retract and release the lifting rope. This technology is an existing technology, which uses the lifting rope to drive the lifting block to descend, so that the connecting block at the bottom of the connecting rod is close to the two ends of the steel, and drives the clamping block at the bottom of the connecting block to descend to the two sides of the steel. At this time, the steel is located between the two clamping blocks, and the clamping assembly works, and the clamping assembly drives the clamping blocks to approach each other, and the clamping blocks and the steel are abutted, and several abutting rollers are abutted against the two ends of the steel at the same time; then, the lifting assembly drives the abutting rollers to rotate, and the abutting rollers use friction The force drives the clamped steel to lift up, so that the steel gradually moves away from the ground between the clamping blocks; finally, the rotating component works to drive the limit block away from the gap, so that the length direction of the limit block is perpendicular to the clamping block. At this time, the limit block is located directly below the steel, and the lifting platform works again to lift the lifting block to lift the steel; the clamping component is used to automatically clamp the steel, the lifting component is used to move the steel away from the ground, and the rotating component is used to rotate the limit block.

The connecting block 21 is provided with a clamping assembly 3 for driving the clamping blocks 22 to slide against each other. , When it is necessary to hoist the steel on the ground, the lifting platform is used to retract and release the lifting rope 1, which can drive the lifting block 11 to descend in the vertical direction, so that the connecting block 21 at the bottom of the connecting rod 2 is close to the two ends of the steel, and drives the clamping blocks 22 at the bottom of the connecting block 21 to descend to both sides of the steel. At this time, the steel is located between the two clamping blocks 22, and the clamping assembly 3 works, and the clamping assembly 3 drives the clamping blocks 22 to approach each other, and the clamping blocks 22 can be against both sides of the steel.

[0031] Reference Figure 2 and Figure 3 The opposite surface of the clamping block 22 is provided with an abutment groove 4 along its length direction, and a plurality of abutment rollers 41 are rotatably arranged in the abutment groove 4. The length direction of the abutment rollers 41 is arranged along the height direction of the clamping block 22. The clamping block 22 is provided with a lifting component 5 that drives the plurality of abutment rollers 41 to rotate simultaneously. The bottom end of the clamping block 22 is also provided with a notch 221, and a limit block 222 is rotatably arranged in the notch 221 through a rotating component 6. After the clamping block 22 is driven by the clamping assembly 3 to abut against both sides of the steel, several abutting rollers 41 can abut against both ends of the steel at the same time. At this time, the lifting assembly 5 drives the abutting rollers 41 to rotate, and the abutting rollers 41 use friction to drive the clamped steel to be lifted, so that the steel gradually moves away from the ground between the clamping blocks 22; finally, the rotating assembly 6 works to drive the limit block 222 away from the notch 221, so that the length direction of the limit block 222 is perpendicular to the clamping block 22.

The tooth pattern 411 and the tooth pattern 52 are meshed with each other. After the clamping assembly 3 drives the clamping blocks 22 to approach each other so that the abutting rollers 41 abut against both sides of the steel, the second motor 51 is used to drive the uppermost abutting roller 41 to rotate, and the tooth grooves 411 on the abutting roller 41 abut against the tooth patterns 52, thereby driving the damping pads 53 to transmit on the abutting rollers 41. The damping pads 53 increase the friction between the abutting rollers 41 and both ends of the steel. At the same time, several abutting rollers 41 support the damping pads 53, and the transmitted damping pads 53 use the friction force to drive the clamped steel to be lifted away from the ground.

The rotating gear 63 and the rotating shaft 62 are coaxially arranged. The piston rod of the cylinder 61 is connected to the telescopic rack 64, and the telescopic rack 64 and the rotating gear 63 are meshed with each other. After the clamped steel is lifted off the ground by the lifting assembly 5, there is a certain gap between the steel and the ground, and the cylinder 61 works at this time, and the piston rod of the cylinder 61 drives the telescopic rack 64 to slide, and the telescopic rack 64 drives the rotating gear 63 to rotate when sliding, and the rotating gear 63 rotates and then drives the rotating shaft 62 to rotate, and after the rotating shaft 62 rotates, the limit block 222 is quickly controlled to move away from the notch 221, and the state of the limit block 222 is quickly changed by the cylinder 61. The limit block 222 can be stored in the notch 221 or perpendicular to the clamping block 22, and the limit block 222 supports and limits the steel when the steel is hoisted, which effectively improves the stability and safety of the steel structure during hoisting.

[0035] Reference Figure 1 and Figure 2 A limit plate 10 is provided at one end of the two connecting blocks 21 that are away from each other. When the connecting rod 2 drives the connecting block 21 to approach the two ends of the steel, the limit plate 10 is used to descend to the two ends of the steel. After the steel is lifted, the limit plate 10 can limit the steel from both ends of the steel, further improving the safety of the steel lifting work and preventing the steel from falling from between the clamping blocks 22.

The adjusting gear 83 and the adjusting disk 71 are coaxially arranged, and the bidirectional rack 84 is meshed with the two adjusting gears 83. The servo motor 81 works, and the servo motor 81 drives the bidirectional rack 84 on the screw rail 82 to slide along the length direction of the screw rail 82. When the bidirectional rack 84 slides, it abuts against the two adjusting gears 83 at the same time, thereby driving the two adjusting gears 83 to rotate, and controlling the adjusting disk 71 to rotate at the same time. The adjusting disk 71 then drives the connecting rod 2 to slide in the adjusting groove 711, and the two connecting rods 2 can be close to each other or away from each other.
