Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a hoisting device for a steel cage for a ground-connected wall. Background Technology

[0002] With the rapid development of the manufacturing and construction industries, there is an increasing number of hoisting equipment used on-site in manufacturing processing, bridge construction, and other fields. In the construction of diaphragm walls, steel cages are usually used, and the spreader beam for hoisting steel cages is a commonly used supporting hoisting tool, which is suspended in the air by a crane.

[0003] According to Chinese Patent CN202220838441.9, a spreader beam for hoisting diaphragm wall reinforcement cages is disclosed. This application includes a spreader beam body and hoisting components. The top of the spreader beam body has a main lifting hole for connecting with a crane; the bottom of the spreader beam body has a sliding groove; two sets of hoisting components are provided, and both hoisting components are slidably hooked in the sliding groove and are spaced apart along the length of the sliding groove; the two hoisting components are used to slide in the sliding groove to a position suitable for the reinforcement cage and are fixed to lift the reinforcement cage. This solves the problem of poor practicality caused by the fixed structure of existing spreader beams for hoisting diaphragm wall reinforcement cages. Existing spreader beams lack a buffer structure for the hooks during hoisting, making them prone to damage due to excessive force during hoisting. Furthermore, existing spreader beams require individual adjustment of the distance between each set of hooks, which is time-consuming and inefficient.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

The adjacent sides of both sets of lead screws 9 extend into the adjusting groove 11 and are respectively connected to helical gears 12. A rotating shaft 13 is provided at the top of the beam 1. The bottom end of the rotating shaft 13 extends into the adjusting groove 11 and is connected to a helical gear 21 that matches the helical gear 12.

[0028] Example 3;

[0029] like Figure 1-5As shown, the structure includes a beam 1, with symmetrically arranged pulley mounting frames 2 at the bottom of the beam 1. Two sets of pulley mounting frames 2 are connected to the beam 1 via a spacing adjustment mechanism. Each pulley mounting frame 2 contains a pulley 3, and the bottom of each pulley 3 contains a reinforcing cage 4. The reinforcing cage 4 is connected to the pulley 3 via a steel wire rope 5. The top of the beam 1 contains a lifting ring 6, which is connected to the beam 1 via a steel wire rope 7.

The two sets of moving blocks 10 then drive the two sets of pulleys 3 to move synchronously closer or further apart. By setting a distance adjustment mechanism, the distance between the two sets of pulleys can be adjusted synchronously, improving its adjustment efficiency and making it suitable for hoisting steel cages of different sizes. During hoisting, the pulleys 3 are moved through... Wire rope 5 is connected to the rebar cage 4. The hook of the crane is hooked onto the lifting ring 6, and then the lifting ring 6 is lifted upward. The lifting ring 6 drives the beam 1 to move upward through wire rope 7. The beam 1 drives the rebar cage 4 to move upward through pulley 3. When pulley 3 lifts the rebar cage 4, it drives two sets of sliders 17 to move close together through two sets of movable connecting rods 20. When the two sets of sliders 17 move close together, they will compress the buffer spring 19 to activate a certain buffering effect. By setting the buffer, the pulley can play a buffering role when lifting the rebar cage, preventing excessive lifting force from damaging the pulley or the rebar cage and improving its safety.

[0031] In summary, by means of the above-mentioned technical solution of this utility model, the distance between the two sets of pulleys can be adjusted synchronously by setting a spacing adjustment mechanism, thereby improving its adjustment efficiency and making it applicable to the hoisting of steel cages of different sizes. By setting a buffer component, when the pulleys lift the steel cage, they can play a buffering role, preventing excessive lifting force from damaging the pulleys or steel cages and improving its safety.
