Background technique

In the current construction process of steel structure buildings of industrial plants, high-rise buildings and large venues, the installation of various types of steel beams and steel columns is the main task of hoisting construction. In the actual hoisting construction process, the components of large steel structural beams and steel columns often have large dimensions and heavy weights. When hoisting steel beams, large lifting lugs must be welded on the upper part of the steel beams or steel beams and steel columns must be hoisted with steel slings. After it is in place, construction workers need to be arranged to climb to the top of the steel column to remove the hoisting shackles. There are many safety hazards during the hoisting process, and the construction is very dangerous, which leads to the difficulty of component installation deviation and position control during the installation and construction process. The lifting method commonly used in the industry has following deficiencies at present:

(1) Set temporary welding lugs at the upper lifting point of the steel beam and hang the hook for lifting. This hoisting method has relatively high requirements on the quality of the weld seams of the temporary welding lugs at the lifting points. and wasted man-hours;

(2) Use a steel sling hoop on the steel beam and then hang a hook for lifting. This hoisting method will easily cause the steel sling to slip, resulting in instability of the suspended component, and a high safety risk factor;

(3) After the steel column is hoisted in place, it needs to be shackled at high altitude, and it is troublesome to unhook the hook, and there is a great potential safety hazard.

Each positioning splint is provided with a cotter pin, one end of the baffle is firmly connected to the cotter pin of the positioning splint through the pin shaft a, and the other end of the baffle is movably connected to the cotter pin of the positioning splint through the spring lock pin. Described spring lock pin is made of support, spring barrel, spring, pin shaft b, and described support is connected with positioning splint, and described spring barrel, spring, pin shaft b are successively connected and arranged on the support at the axis position, and described pin shaft b is a structure with a slightly larger diameter at one end and a protrusion in the middle.

Further, the main body of the inverted U-shaped frame is formed of steel plates welded with square steel.

Further, a lifting hole is opened at the center of the upper end of the inverted U-shaped frame, and a backing plate is provided for reinforcement.

Further, a limit block is provided at one of the lower ends of the inverted U-shaped frame.

Further, a pull ring is provided at the tail end of the pin b, and a pull rope is connected to the pull ring.

Further, a pulley is connected to the outer end of the bracket.

Compared with the prior art, the beneficial effects obtained by the utility model are as follows:

The utility model is simple in structure, easy to use, does not need to install connecting pieces on the original steel beam column, does not damage the base material of the steel beam column, and the force distribution is reasonable during the hoisting process of the steel beam column, and the lifting and lowering of the steel beam column is stable. The deformation of steel beams and columns is easy to lift and hook unloading, and the whole set of devices can be reused, with strong practicability, which can greatly improve work efficiency, reduce hoisting costs, ensure the quality of steel structure installation, and reduce safety risks when working at heights.
