Abstract

The invention provides a detachable lifting device for a door-like mast building and a construction method of the lifting device. The lifting device comprises a base fixed to a foundation structure, a door-like mast rotatably connected to the base, a lifting mechanism mounted on the door-like mast and connected to equipment required to be hoisted and a pull adjusting mechanism connected to the door-like mast, the included angle between the door-like mast and the base is adjusted through pulling of the door-like mast so that the door-like mast is lifted. The lifting mechanism on the door-like mast is used for fixing the equipment required to be lifted and hoisted; the door-like mast is pulled through the pull adjusting mechanism, and the equipment is lifted; and the detachable lifting device is simple and stable in structure, all components can be adjusted according to actual construction sites, and compared with a traditional single-arm lifting structure, the door-like mast is more stable.

Description

technical field [0001] The invention relates to the field of hoisting and hoisting of small and medium-sized materials in the construction industry, and directly relates to a detachable hoisting device for gantry mast construction. Background technique [0002] Generally, construction sites use small poles for hoisting when hoisting materials or equipment in the floor. Its disadvantages are: 1) Poor safety, low lifting capacity brings different degrees of difficulty to hoisting construction; 2) The use efficiency is very low; 3) It is difficult to move, and it needs to be completely dismantled every time it is moved, and then installed and debugged again. The above problems have been difficult to adapt to the high-speed development of the construction site. . Contents of the invention [0003] In view of the foregoing, the present invention now provides a detachable portal mast construction lifting device to solve the disadvantages of traditional lifting devices such as ...
