Auxiliary device for hoisting cantilever steel truss and using method

Abstract

The invention provides an auxiliary device for hoisting a cantilever steel truss and a using method. The auxiliary device comprises a positioning pile, a positioning seat, a rotary adjusting mechanismand a steel truss butt joint mechanism, wherein the positioning seat is arranged at the center of the top surface of the positioning pile, and a mounting groove is formed in the center of the top ofthe positioning seat; the rotary adjusting mechanism comprises a rotary seat and a limiting assembly, the rotary seat is arranged in the mounting groove, and the limiting assembly is matched with therotary seat for limiting; the steel truss butt joint mechanism comprises a movable seat, a left movable column, a right movable column, a steel truss connecting assembly and a bidirectional movement adjusting assembly; the center of the bottom of the movable seat is connected with the top of the rotary seat; a movable groove is formed in the top of the movable seat; the left movable column and theright movable column move along the movable groove; the steel truss connecting assembly is arranged at the tops of the left movable column and the right movable column; and the bidirectional movementadjusting assembly is matched with the left movable column and the right movable column for adjustment. The auxiliary device can be in butt joint with the steel truss quickly, horizontal and stable conveying of the steel truss is guaranteed in the hoisting process, the hoisting accident rate is reduced, and the hoisting positioning accuracy and the construction efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of house construction, and in particular relates to an auxiliary device for hoisting a cantilevered steel truss and a method for using it. Background technique [0002] Housing construction engineering is generally referred to as construction engineering, which refers to various technical work such as survey, planning, design, construction, installation and maintenance and the completed engineering entities for new construction, reconstruction or expansion of housing buildings and auxiliary structures. [0003] During the hoisting of high-altitude steel trusses during house construction, the steel trusses are planned to be hoisted by truck cranes. However, during the hoisting process, only steel wire ropes are used for hoisting. There are multiple free ends of the steel trusses, which are easily affected by wind force and crane swing. Shaking, on the one hand, the swing speed is slow and easy to collide with...

[0003] During the hoisting of high-altitude steel trusses in the building process, the steel trusses are planned to be hoisted by truck cranes, but during the hoisting process, only steel wire ropes are used for hoisting, and there are multiple free ends of the steel trusses, which are affected by wind force and crane swing, and are easily Shaking, on the one hand, the swing speed is slow and easy to collide with other components through the control of the truck crane, resulting in damage to the finished product and potential safety hazards. An auxiliary device for the hoisting of cantilevered steel trusses is proposed to solve this problem
