Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a steel bar hoisting and clamping device for construction engineering. Background Art

[0002] Construction engineering is a part of construction engineering, which refers to the engineering entity formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. It includes factories, theaters, hotels, shops, schools, hospitals and residences, etc., to meet people's needs for production, residence, study, public activities, etc.

[0003] A Chinese patent with publication number CN220596779U was searched and disclosed a steel bar hoisting and clamping device for construction engineering.

[0004] The above technical scheme includes: a bottom plate, a steel bar placement opening is opened at the top center of the bottom plate, a rubber anti-skid pad is fixedly connected to the top of the steel bar placement opening, four corners of the top of the bottom plate are fixedly connected to support columns, the tops of the four support columns are fixedly connected to the top plate, and the top of the top plate is fixedly connected to a connecting block. When in use, workers move the steel bar to the bottom plate and place it in the steel bar placement opening, move the connecting rod downward through the groove through the moving ring, drive the fixed block to move to the top of the steel bar for fixing, then pull the moving ring onto the fixed block for installation, install the bolts on the moving ring, and fix and lock the moving ring by tightening the nuts. The rubber anti-skid pad can effectively prevent the steel bar from scratching out of the steel bar placement opening when lifted into the air, and the four support columns cooperate with the top plate to strengthen and reinforce the bearing capacity of the equipment;

[0005] However, in the above scheme, when clamping the steel bars, this technology needs to insert the steel bars into the steel bar placement opening, and the weight of the steel bars is often several tons. Therefore, this technology is not convenient for clamping the steel bars. When fixing the steel bars, this technology clamps the steel bars by moving the fixing block downward, but there is a gap between the fixing block and the bottom plate, especially when fixing multiple steel bars, the fixing block cannot completely fit the steel bar placement opening, and the steel bars will slip from the gap. This technology connects the upper and lower parts through a steel wire rope. During hoisting, the steel wire rope lacks rigidity, the steel bars will shake greatly, and the stress is concentrated at the contact point between the steel wire rope and the load-bearing rod during hoisting, which can easily cause deformation of the component.

[0006] For this reason, we propose a steel bar hoisting and clamping device for construction engineering. Utility Model Content
