Method for hoisting ultra-high overweight equipment in closed workshop and special sling

Abstract

The present invention relates to a method for hoisting ultra-high overweight equipment in closed workshop and a special sling. The hoisting method includes steps as follows: constructing an inclined slope near an equipment installing base; turning the equipment for making the installing direction in a right direction; parallel moving the equipment to a place near the inclined slope; placing the equipment on the inclined slope; raising up the equipment slowly and placing on the inclined slope bottom platform; hoisting the equipment in position cooperating with the special sling; the special sling includes a first girder, a second girder, a hanging ear, the first girder connects with the second girder showing included angle, one side of the first girder far from the second girder is equipped with a first girder hanging ear, two sides of the second girder are equipped with a second girder hanging ear. The method uses two hydrostatic triggers, a bridge type hoisting engine in workshop and the sling for cooperating lifting the ultra-high overweight equipment which can solve problem of insufficient weight-lifting capability; the inclined slope for storing equipment temporarily near the equipment base which can solve defect of limited workshop beam orbital height by ultra-high.

Description

Technical field [0001] The invention relates to the technical field of hoisting heavy equipment in a factory building, in particular to a method and a special hoisting tool for hoisting ultra-high and overweight equipment in a closed factory. Background technique [0002] Generally, large-scale lifting equipment is used to install super-high and over-heavy equipment in the plant. However, due to the elevation of the crane beam track of the large-scale lifting equipment, and the height of the plant is restricted, the use of large-scale lifting equipment in the plant is not realistic. For example, when installing large-diameter thick-walled rolling pipelines, the frame weight of the punching hydraulic press reaches 200t, the height of 15.8m exceeds the elevation of 15m of the crane beam track surface, and the conditions of the site and surrounding environment are restricted, and the installation area cannot use one or two. Large lifting equipment, such as hydraulic cranes or crawle...
