Description

A type of anti-sway block hoisting cage Technical Field

[0001] This utility model relates to the field of construction machinery technology, specifically to an anti-sway block hoisting cage. Background Technology

[0002] In the construction industry, block hoisting cages are key equipment for the vertical transportation of blocks, especially suitable for high-rise buildings and secondary structure construction. Traditional hoisting cages mostly adopt a fixed structure, consisting of wire ropes or a rigid frame. During hoisting, the fixing device needs to be repeatedly disassembled and reassembled to load and unload blocks. During hoisting, the blocks, lacking effective limiting and fixing measures, are easily swayed by external forces or inertia, leading to block detachment or even safety accidents. Therefore, there is an urgent need for an anti-sway block hoisting cage to solve the above problems. Summary of the Invention

Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] Please refer to Figures 1 to 4. This utility model embodiment provides an anti-sway block hoisting cage, including: two side plates 1, a back plate 2, a flap 3, a positioning rod 5, and an electromagnetic chuck 6; the two side plates 1 are arranged in parallel, the back plate 2 is arranged between one end of the two side plates 1, and the bottom of the flap 3 is rotatably connected between the bottoms of the other ends of the two side plates 1.

[0022] Two limiting grooves 4 are provided on both sides of the inner wall of the side plate 1. The limiting grooves 4 extend vertically, with their tops penetrating the upper surface of the side plate 1 and their inner sides penetrating the inner wall of the side plate 1. A positioning rod 5 is installed in the limiting groove 4, perpendicular to the inner wall of the side plate 1. Telescopic adjustment rods 23 are provided on both sides of the back plate 2 and the flip plate 3, with an electromagnetic chuck 6 connected to the inner end of the telescopic adjustment rod 23. The telescopic adjustment rods 23 on both sides of the back plate 2 and the flip plate 3 are telescopic. The electromagnetic chuck 6 at their inner ends is fixed by adsorbing the pre-embedded steel bars or external angle steel inside the block, thus constraining the block and effectively suppressing hoisting sway. The telescopic adjustment rod 23 can specifically be in the form of a screw.

[0023] Specifically, the outer walls of the two side plates 1, the back plate 2, and the flap 3 are each provided with two parallel horizontal back ribs 7. The horizontal back ribs 7 are welded from channel steel or H-beams and form a box-shaped structure with the side plates 1. This design evenly distributes the lifting load to the entire frame, improves the load-bearing capacity of the lifting cage, and resists the torsional load caused by the swing of the wire rope during the lifting process, thus avoiding structural deformation.

[0024] Specifically, the cross-sectional shape of the limiting groove 4 includes several parallel and spaced rectangular slots 19 and a through groove 20 vertically connected to the middle of the rectangular slots 19, the through groove 20 penetrating the inner wall of the side plate 1.

[0025] Specifically, the positioning rod 5 includes a locking block 22 and a positioning rod body 21 vertically connected to the locking block 22. The cross-sectional shape of the locking block 22 matches the rectangular locking groove 19, and the width of the positioning rod body 21 matches the through groove 20. The locking block 22 is installed in the rectangular locking groove 19, which extends from the through groove 20 to the inner side of the side plate 1. By adjusting the position of the positioning rod 5 in the limiting groove 4, lateral limiting of blocks of different specifications can be achieved to prevent horizontal displacement.

[0026] Specifically, a top plate 12 is provided on the top of the side plate 1 and the flip plate 3, and lifting lugs 8 are provided at both ends of the top plate 12 of the side plate 1.

[0027] Specifically, a base plate 13 is provided at the bottom of the side plate 1 and the flip plate 3. A pivot mounting seat 14 is provided at one end of the base plate 13 of the side plate 1, and pivots 16 are provided at both ends of the bottom of the flip plate 3. The pivots 16 are rotatably connected to the pivot mounting seat 14. This split design allows the flip plate 3 to be flipped down and opened, facilitating quick loading and unloading of blocks. The top plate 12 at the top of the side plate 1 and the flip plate 3 forms a closed frame. The lifting lugs 8 at both ends of the top plate 12 of the side plate 1 are made of high-strength steel and are directly connected to the lifting equipment. Its advantage is that it simplifies the operation of the lifting hook and improves the load-bearing reliability. The base plate 13 at the bottom cooperates with the pivot mounting seat 14, and the pivots 16 are embedded in the pivot mounting seat 14 to achieve smooth rotation of the flip plate 3.

[0028] Specifically, a first chain fastener 9 is provided on the outer side of the top end of the side panel 1, and second chain fasteners 10 are provided on both ends of the outer side of the top of the flip panel 3. A chain 11 connects the first chain fastener 9 and the second chain fastener 10. The first chain fastener 9 on the outer side of the top of the side panel 1 and the second chain fastener 10 on the top of the flip panel 3 are connected by the chain 11. The length of the chain 11 is adjustable and is used to limit the maximum opening angle of the flip panel 3 to avoid excessive flipping that could cause equipment damage or operational risks.

[0029] Specifically, a horizontal plate 15 is connected between the bottoms of the two rotating shaft mounting bases 14. The bottom surface of the horizontal plate 15 is flush with the bottom surface of the base plate 13. Two parallel slots 17 are provided at both ends of the bottom of the horizontal plate 15 and the base plate 13, and pins 18 are installed in the slots 17. During hoisting, the pins 18 provide rigid support for the bottom of the block, and together with the adsorption effect of the electromagnetic chuck 6, they form a three-dimensional protection, significantly improving the safety of hoisting.

[0030] This invention solves the swaying problem caused by traditional hoisting cages relying solely on gravity for fixation by using a limiting groove 4 and a positioning rod 5 for lateral limiting and an electromagnetic chuck 6 for vertical adsorption, forming a two-way constraint. The three-dimensional frame formed by the horizontal back rib 7, top plate 12, and bottom plate 13 significantly improves the resistance to deformation and can support heavier blocks. The multi-level rectangular slot 19 design of the limiting groove 4, combined with the telescopic function of the telescopic adjustment rod 23, allows the device to adapt to blocks of different sizes, making it highly versatile. The opening angle of the hinge 16 of the flip plate 3 is controlled by a chain 11, and the electromagnetic chuck 6 adsorbs when energized and releases when de-energized, greatly improving loading and unloading efficiency. When energized, the electromagnetic chuck 6 generates a strong magnetic force that can penetrate the surface of the block and adsorb the internal embedded steel reinforcement or external welded angle steel, forming a vertical fixation constraint. This dual fixing mechanism of mechanical limiting and electromagnetic adsorption significantly improves safety compared to traditional hoisting methods that rely solely on gravity, and is especially suitable for high-rise buildings with high wind loads.
