C-shaped hoisting device for positions under beam and plate

Abstract

The invention relates to a C-shaped hoisting device for positions under a beam and a plate. The C-shaped hoisting device comprises a balance system, a conversion system, a universal adjusting system,a component supporting rod, an auxiliary hoisting lug and a safety rope. The balance system is mounted on the conversion system. The universal adjusting system is connected with the bottom of the conversion system. The component supporting rod is mounted on the universal adjusting system. The conversion system comprises a hoisting sling and a C-shaped hoist frame. A main hoist point and an auxiliary hoist point are fixedly connected with the left side and the right side of the top of the C-shaped hoist frame correspondingly. The main hoist point is connected with one end of a chain block. Theother end of the chain block is connected with the hoisting sling. The other end of the hoist sling is connected with the auxiliary hoist point. The mounting problem of components under the beam and the plate is solved through the newly designed C-shaped hoisting device, thus, the horizontal shift-in distance of the components is enlarged, the vertical hoisting state of the components is achievedthrough the universal adjusting system, the limitation of insufficient hoisting spaces is broken, the hoisting efficiency is improved, and the hoisting risks are lowered.

Description

technical field [0001] The invention relates to the technical field of hoisting devices, in particular to the technical field of a C-shaped hoisting device under beams and slabs. Background technique [0002] With the installation needs of steel structures in modern society, there are more and more steel structure projects, and the volume is getting bigger and bigger. The weight and specifications of the current steel structures are changing, especially in the hoisting of steel components, which is limited by the steel structure design and the on-site production and installation environment. More and more steel components are hoisted due to the limitations of height, space and other working surfaces. For hoisting under the beam or under the slab, the traditional hoisting method is inefficient or even impossible to achieve smooth hoisting.

Problems solved by technology

The weight and specifications of the current steel structures are changing, especially in the hoisting of steel components, which is limited by the steel structure design and the on-site production and installation environment. More and more steel components are hoisted due to the limitations of height, space and other working surfaces. For hoisting under the beam or under the slab, the traditional hoisting method is inefficient or even impossible to achieve smooth hoisting

[0003] The traditional hoisting method uses an inverted chain on the inside of the hoisted component to limit the horizontal movement of the component, pull the sling above the component at a certain oblique angle, lift the component, and slowly release the inverted chain to move the component out of the beam, plate, or tighten it. The chain moves the component under the component. The moving distance of the component is small, the efficiency is low, and there is a greater safety risk; the C-type lifting tool is a simple and efficient lifting tool, and it is also a lifting tool that is used more frequently.

Installing the traditional C-shaped lifting device on the sling can increase the lifting distance, but the lifting device is prone to tilt when the lifting weight changes, and cannot be used in a small space; directly using the C-shaped lifting device cannot realize vertical components In the vertical state under the beam, and in the case of hoisting components of different weights, the angle of the C-type hoisting device is always inclined, which cannot realize hoisting operations in a small space, and there is a risk of collision with other components
