Abstract

The invention relates to a construction method of a mechanical lifting device, and belongs to the technical field of construction machinery equipment. The construction method of the mechanical liftingdevice is used for solving the problem of handling of a unit body structure at the position with a complex building structure and small construction space at which a tower crane cannot be installed.The mechanical lifting device includes a frame platform fixed to a roof through fixing supports which are vertically arranged, a fixed arm and an adjustment arm, wherein the fixed arm and the adjustment arm are fixed to the frame platform. The frame platform is further provided with a hoist and a counterweight, and a drum of the hoist is wound with a wire rope. The end, provided with a hook, of the wire rope bypasses guide pulleys fixed to the adjustment arm to be overhung. One end of the fixed arm is fixed to the frame platform, and a row of bolt holes are formed in the fixed arm in the length direction of the fixed arm. The adjustment arm and the fixed arm are connected through bolts. The counterweight is arranged on the side, away from the fixed arm, of the frame platform. The mechanical lifting device realizes the handling of the unit body structure under the conditions that the building structure is complex, the construction space is small or the tower crane is removed.

Description

technical field [0001] The invention relates to the technical field of construction machinery and equipment, in particular to a construction method of a mechanical hoisting device. Background technique [0002] In the process of engineering construction, there is an increasing demand for unit structures, mainly using larger unit structures to complete the construction of building structures. However, compared with a single component, the volume and weight of the unit structure itself is relatively large, so how to transport the unit structure to the upper floor of the building has become an urgent problem in the construction process. Usually, tower cranes are generally used for transportation when site conditions permit. However, tower cranes cannot be installed in locations with complex building structures and small construction space. [0003] Therefore, how to realize the handling of the unit structure under the condition of complex building structure, small constructio...
