Problems solved by technology

[0004] With the rapid development of bridge steel structure installation technology, a large number of tools such as small electric welding machines and oxygen acetylene cylinders need to be transported to the bridge deck during on-site installation. Traditional manual transport is no longer suitable. Hoisting, due to the limitation of the construction site conditions, not only cannot flexibly hoist the required tools in place, but also greatly increase the construction cost

Abstract

The invention discloses a simple hoisting device for steel structure bridge installation, which comprises a column installed on a bridge floor, a back pull rod, and a hoist, wherein the back pull rod is connected with the column; a closed three-wheel tackle and an inclined pulley are respectively mounted on the column; the column is connected with one end of a rotation arm, and a fixed pulley is mounted on the other end of the rotation arm; a lifting steel wire rope is mounted on the hoist; the lifting steel wire rope is connected with an object to be hoisted through the inclined pulley, the closed three-wheel tackle, and the fixed pulley in order. The invention provides a simple hoisting device for steel structure bridge installation, which is simple in structure and convenient for mounting and dismounting, can hoist appliances to the bridge floor rapidly and conveniently according to actual demand, reduces labor force and construction cost, and also greatly improves production efficiency.

Description

[0001] technical field [0002] The invention relates to a simple hoisting device for steel structure bridge installation. [0003] Background technique [0004] With the rapid development of bridge steel structure installation technology, a large number of tools such as small electric welding machines and oxygen acetylene cylinders need to be transported to the bridge deck during on-site installation. Traditional manual transport is no longer suitable. Hoisting, due to the limitation of the construction site conditions, not only cannot flexibly hoist the required tools in place, but also the construction cost is greatly increased. [0005] Contents of the invention [0006] In order to solve the above problems, the object of the present invention is to provide a simple hoisting device for steel structure bridge installation, which has a simple structure and is convenient to assemble and disassemble, and can quickly and conveniently hoist appliances to the bridge deck a...
