Automatic unhooking device for hoisting of multiple steel structure columns

Abstract

The invention relates to the technical field of hoisting equipment, and discloses an automatic unhooking device for hoisting of multiple steel structure columns. The device comprises a U-shaped fixing frame, each of the outer walls of the two sides of the U-shaped fixing frame is fixedly connected with two hanging rings, and the outer walls of the two hanging rings on the same side are jointly and fixedly connected with a steel wire rope; the outer walls of the two sides of the U-shaped fixing frame are movably sleeved with moving sleeves, the outer walls of the two moving sleeves are jointly and fixedly connected with a fixing block, the side wall of the U-shaped fixing frame is fixedly connected with a fixing plate, and the outer wall of the fixing plate is fixedly connected with a pushing mechanism and a control mechanism; and the outer wall of the side, away from the fixing plate, of the U-shaped fixing frame is fixedly connected with an oil supply mechanism. According to the automatic unhooking device for hoisting of the multiple steel structure columns, the automatic unhooking function of the multiple steel structure columns during hoisting can be achieved, the efficiency and convenience of hoisting of the multiple steel structure columns are improved, meanwhile, the working safety of constructors is improved, and the labor intensity of the constructors is reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an automatic decoupling device for hoisting a steel structure multi-section column. Background technique [0002] Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and is made of silanized, pure manganese and phosphorus Chemical, washing and drying, galvanizing and other rust removal and antirust processes. The components or parts are usually connected by welds, bolts or rivets. Because of their light weight and easy construction, they are widely used in large factories, venues, super high-level fields. [0003] At present, the joints of the upper and lower steel columns are welded to temporarily install the positioning lugs, which also serve as hoisting lugs. However...

AI Technical Summary

Problems solved by technology

[0003] At present, the butt joints of the upper and lower steel columns are welded to temporarily install the positioning lugs, which also serve as hoisting lugs. However, when hoisting the steel structure multi-section columns, it is necessary to use slings to connect the steel structure sections. Climb the ladder to the top of the column, and open the snap ring on the sling to separate the sling from the steel column to complete the hoisting process. During the hoisting process, the construction personnel need to go up the ladder to the top of the steel column to remove the hook, which not only affects the multi-section steel structure The efficiency and convenience of column hoisting also affect the safety of construction personnel and increase the labor intensity of construction personnel.
