Description

Technical Field

[0001] The present invention relates to the technical field of hoisting building construction profiles, and more specifically, to a safety hoisting device for building construction profiles. Background Art

[0002] Building construction hoisting refers to the construction work of using hoisting equipment to lift prefabricated components or structures made in factories or on construction sites, move them to designated positions, and install and fix them. According to different hoisting methods, it can be divided into piecemeal hoisting and integral hoisting. Piecemeal hoisting is to hoist each component of a building or structure in turn, while integral hoisting is to assemble each component into an integral structure on the ground and then hoist it. Hoisting equipment is required during construction hoisting.

[0003] After retrieval, according to the patent network CN117466165B, a safety hoisting device for building construction includes an overweight warning type hoisting body, a fitting and fastening device, and an annular bundling and tightening device. This invention belongs to the technical field of building safety hoisting, and specifically, it is a safety hoisting device for building construction. According to the situation that steel bars are prone to slipping during hoisting, a method combining end alignment and fitting fastening with automatic annular anti-slip tightening is adopted to achieve the technical effect of firmly bundling the steel bars in all directions, effectively preventing the steel bars from slipping during hoisting; to prevent the hoisting equipment from being prone to break in the air when overweight, resulting in worker injuries, a method of pre-measuring the weight of the steel bars to be hoisted is adopted to achieve the technical effect of safely hoisting the steel bars.

[0004] After retrieval, according to the patent network CN118597955B, a safety hoisting device for building construction belongs to the technical field of safety hoisting, and includes: a hanging frame and a lifting lug seat. The lifting lug seat is arranged at the top of the hanging frame, and the lifting lug seat is connected to the hook body of the lifting equipment through a top lifting lug; a center of gravity stabilizing mechanism, the center of gravity stabilizing mechanism is connected to the top of the hanging frame, and the center of gravity stabilizing mechanism includes a plurality of connecting rods arranged on the peripheral side of the bottom of the lifting lug seat. The connecting rods are configured to move the ends along the length direction of the hanging frame. In this invention, when the end face closing disk drives the limiting sleeve to move into the pipe opening, the limiting sleeve can support the inner side wall of the pipe. Through the abutting support on the hollow cavity wall, the force bounce at the end of the pipe during hoisting is reduced, the hoisting stability and the regularity of the pipe before and after hoisting are improved, the bending of the too-thin pipe due to external interference during hoisting is avoided, and the adaptability to the working environment is improved.

[0005] However, when the existing safety hoisting device is in use, although it can stably hoist building construction materials, when it is necessary to hoist square and circular building profiles, the conversion and fixing hoisting effect of the hoisting equipment on building materials of different shapes is not high. When the hoisting equipment hoists building materials of different shapes, it will cause the connection adaptability between the hoisting equipment and the materials to decrease, affecting the stability of the materials during hoisting and reducing the safety of the hoisting equipment during long-term use. Moreover, when hoisting building profiles through the hoisting equipment, the convenience of automatically pushing and discharging square profiles from the side wall of the material placement rod is not high. When it is necessary to discharge profiles from the side wall, construction workers need to rely on brute force to pull the profiles, reducing the discharging efficiency of the construction workers for the hoisted materials, which does not meet the usage requirements of people. Therefore, we propose a safety hoisting device for building profiles in construction. Summary of the Invention
