Detailed Description of the Preferred Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

A cross bar 3 is fixedly installed inside the cross beam 1. Two moving blocks 4 are slidably installed on the outer side of the cross bar 3. Connecting columns 5 are fixedly installed at the bottoms of the two moving blocks 4.

[0027] Among them, a moving hole is opened at the bottom of the cross beam 1. The connecting column 5 passes through the moving hole to the outside of the cross beam 1. The number of cross bars 3 is two.

[0028] Please refer to Figures 1 to 3 , mounting blocks 6 are fixedly installed at the bottoms of the two connecting columns 5. Lifting lugs 7 are fixedly installed at the top of the longitudinal beam 2 and the bottom of the mounting block 6. A U-shaped buckle 8 is clamped inside the two groups of lifting lugs 7. A steel wire rope 9 is arranged inside the U-shaped buckle 8.

[0029] It should be noted that for the spreader used for hoisting large-diameter steel reinforcement cages, by installing a reinforcement and adjustment assembly, the device has good load-bearing capacity and stability, ensuring the safety and reliability of the hoisting process, and can adjust the distance between the U-shaped buckles 8 on the two mounting blocks 6, and adjust the hoisting according to the diameter of the steel reinforcement cage, improving the stability performance of the device during hoisting.

[0030] Specifically, when using the spreader for hoisting large-diameter steel reinforcement cages, the limit between the two mounting blocks 6 is released. According to the diameter of the hoisted steel reinforcement cage, the two mounting blocks 6 are toggled to move. The moving block 4 is driven by the connecting column 5 to slide on the cross bar 3, and the distance between the two U-shaped buckles 8 on the mounting block 6 is adjusted. Then, the mounting block 6 is limited and fixed, which is convenient for better hoisting the steel reinforcement cage, improving the stability performance of the device during hoisting, facilitating to meet the use requirements. At the same time, the cross structure design provides four lifting points, ensuring the verticality and stability of the steel reinforcement cage during hoisting, and improving the hoisting efficiency and safety of large-diameter steel reinforcement cages.

[0031] Embodiment 2: Please refer to Figure 3 and Figure 5 , on the basis of Embodiment 1, a fixing assembly is further installed on the cross beam 1. The fixing assembly includes fixing blocks 10 fixedly installed on the opposite sides of the two groups of mounting blocks 6. A cross plate 11 is fixedly installed inside the two groups of fixing blocks 10. Slide bars 12 are fixedly installed on the tops of the two groups of cross plates 11.

[0032] Mounting plates 13 are slidably connected to the outer sides of the two slide bars 12. Slide holes are opened on the opposite sides of the two groups of fixing blocks 10. The mounting plate 13 extends to the outside of the fixing block 10 through the slide hole.

[0033] Mounting columns 19 are fixedly installed at the bottoms of the two groups of mounting plates 13. Through holes are opened inside the cross plate 11. The mounting column 19 passes through the through hole to the outside of the cross plate 11.

[0034] It should be noted that clamping devices 14 are fixedly installed on the opposite sides of the two groups of mounting plates 13. The clamping device 14 is composed of a connecting block and a clamping block. Two clamping blocks are fixedly installed at the top of the connecting block, and a number of clamping grooves are formed at the bottom of the cross beam 1. The clamping blocks are clamped with the cross beam 1 through the clamping grooves.

[0035] Extrusion springs 15 are fixedly installed inside the two groups of fixing blocks 10. T-shaped limiting rods 16 are fixedly installed on the opposite sides of the two groups of extrusion springs 15. A sliding groove is formed at the bottom of the cross plate 11. The T-shaped limiting rod 16 is slidably connected with the cross plate 11 through the sliding groove to provide guidance for the movement of the T-shaped limiting rod 16. Vertical blocks 17 are fixedly installed at the bottom of the two groups of cross plates 11.

[0036] Among them, a plugging hole is formed on one side of the vertical block 17. The T-shaped limiting rod 16 is plugged with the vertical block 17 through the plugging hole, which is convenient for limiting the mounting column 19, and further limiting and fixing the clamping device 14, so that the clamping device 14 is better clamped with the cross beam 1.

[0037] L-shaped pull rods 18 are fixedly installed on the opposite sides of the two groups of T-shaped limiting rods 16. Through holes are formed on the opposite sides of the two fixing blocks 10. The L-shaped pull rods 18 extend to the outside of the fixing blocks 10 through the through holes, which is convenient for the user to pull the L-shaped pull rods 18 to move.

[0038] It should be noted that for the spreader for hoisting large-diameter steel reinforcement cages, by installing a fixing component, it is convenient to fix the two groups of U-shaped buckles 8 after adjustment, which is convenient for the device to carry out hoisting work and improves the flexibility of the device.

[0039] Specifically, when the spreader for hoisting large-diameter steel reinforcement cages is used, by pulling the two L-shaped pull rods 18, the extrusion springs 15 are compressed, so that the two groups of T-shaped limiting rods 16 move, releasing the clamping with the vertical blocks 17. Then it is convenient for the mounting column 19 to move downwards, synchronously driving the mounting plate 13 to move downwards on the sliding rod 12, so that the clamping device 14 moves downwards synchronously, releasing the clamping between the clamping device 14 and the cross beam 1, and then it is convenient for the user to adjust the distance between the two groups of mounting blocks 6.

[0040] The working principle of the above embodiment is:

[0041] (1) When the shoulder pole used for lifting a large-diameter steel cage is used, the limit between the two groups of mounting blocks 6 is released, and the two groups of mounting blocks 6 are moved according to the diameter of the steel cage to be lifted. The moving block 4 is driven to slide on the cross bar 3 through the connecting column 5, and the spacing between the two groups of U-shaped buckles 8 on the mounting block 6 is adjusted. Then, the mounting block 6 is limited and fixed, which is convenient for better lifting of the steel cage, improves the stability of the device lifting, and is convenient to meet the use requirements. At the same time, the cross structure design provides four lifting points to ensure the verticality and stability of the steel cage during the lifting process, thereby improving the lifting efficiency and safety of the large-diameter steel cage.

[0042] (2) When the shoulder pole used for lifting a large-diameter steel cage is used, the two L-shaped pull rods 18 are pulled to compress the extrusion spring 15, so that the two groups of T-shaped limit rods 16 move, releasing the clamping connection with the vertical block 17, thereby facilitating the downward movement of the mounting column 19, and synchronously driving the mounting plate 13 to move up and down on the slide bar 12, so that the clamping device 14 moves downward synchronously, releasing the clamping connection between the clamping device 14 and the crossbeam 1, thereby facilitating the user to adjust the distance between the two groups of mounting blocks 6.
