Lifting appliance for perforated steel structure component

Abstract

The invention discloses a lifting appliance for a perforated steel structure component. The lifting appliance comprises a lifting lug, a first lifting plate, a second lifting plate, a movable tongue plate and a pushing device, wherein the middle part of the movable tongue plate is rotatably mounted on the lower sections of the first lifting plate and the second lifting plate through an articulating shaft; the articulating shaft divides the movable tongue plate into a long plate section and a short plate section; the pushing device comprises a pushing plate and a handle; the lower end of the pushing plate is correspondingly matched with the short plate section of the movable tongue plate; a hanging slot is formed in the long plate section; hanging pins are arranged on the first lifting plate and the second lifting plate; the lower end of the pushing plate pushes the short plate section so that the movable tongue plate rotates to hook the hanging slots on the hanging pins; when the hanging slots are separated from the hanging pins, the upper side edge of the movable tongue plate is a hanging edge in contact with the steel structure component. The lifting appliance can be inserted into the hole to lift the perforated steel structure component, thus, the lifting point can be selected reasonably, stress on the component is more reasonable during the lifting, and the safety is higher.

Description

technical field [0001] The invention relates to a hanger, in particular to a hanger for a steel structural component with holes. Background technique [0002] Steel structural components are structures mainly composed of steel materials and are 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. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and easy construction, it is widely used in large factories, stadiums, super high-rises and other fields. However, there is a steel structural member that is relatively large in volume and has a flat panel with multiple through holes. The hoisting of this rigid structural member is more complicated. The current method can only be installed after the hoisting fixture is installed around the steel structure. lift. However, due to the large size of the s...

However, there is a steel structural member that is relatively large in volume and has a flat panel with multiple through holes. The hoisting of this rigid structural member is more complicated. The current method can only be installed after the hoisting fixture is installed around the steel structure. to lift

However, due to the large size of the steel structure components, and there is no lifting point in the middle of the panel, the force of the entire component is unreasonable during hoisting, and the lifting fixture is prone to loosening during lifting and transfer
