Lower jacking fast installation type lifting platform and construction method

Abstract

The invention relates to a lower jacking fast installation type lifting platform. An assembly type steel structure foundation is fixed on a ground foundation on one side of an original bearing platform of a building in a spaced mode. A jacking system is fixedly installed at the upper end of the assembly type steel structure foundation. A plurality of standard knots are installed on the jacking system coaxially in the longitudinal direction in a stacked mode. The height of the upper ends of the standard knots is the same as that of the original bearing platform of the building. A lifting bearing frame is fixedly installed at the upper ends of the standard knots. A stretching type bearing table is installed on one sides of the upper portions of the standard knots in a cantilever type mode. The cantilever end of the stretching type bearing table is connected with the upper end of the original bearing platform of the building in a flush butt-joint mode. A pull rod is connected between one side of the lifting bearing frame and the building. After the fast installation type lifting platform is used for site-in construction of indoor substation electrical equipment, the risks of equipment toppling and platform collapsing are avoided, meanwhile, construction efficiency is improved greatly, original platform preparation time of 10 hours is shortened to 2 hours, the lower jacking fast installation type lifting platform can be repeated used and is suitable for lifting transfer of various heights, and construction cost is lowered greatly.

Description

technical field [0001] The invention belongs to the field of electric power construction auxiliary equipment, in particular to a bottom-lifting quick-loading hoisting platform and a construction method. Background technique [0002] When the electrical equipment of the indoor substation enters the site, the hoisting platform reserved by the building itself is often restricted by the design of the site space, which greatly reduces the efficiency of the equipment entering the site. Go directly to the installation area on the second floor and above. [0003] In actual operation, at present, there are mainly two methods of erecting scaffolding hoisting platform or road timber assembly platform. Not only the construction efficiency is low, but also there are serious risks of hoisting risk and platform collapse. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a quick-mounted lifting platform a...
