Hydraulic lifting upside-down mounting method

Abstract

The invention discloses a hydraulic lifting upside-down mounting method. A hydraulic lifting device lifts an upper straight cylinder section upwards through a temporary lifting tool supported on the upper straight cylinder section, a reducing section is mounted at the lower part of the upper straight cylinder section, a first band plate section of a lower straight cylinder section is mounted at the lower part of the reducing section, a hole corresponding to the hydraulic lifting device is formed in the reducing section, the hydraulic lifting device is moved to be close to the wall face of the first band plate section, the top of the hydraulic lifting device penetrates out of the hole, and then the hydraulic lifting device supports and lifts the first band plate section so that the remaining lower straight cylinder section can be mounted on the lower part of the first band plate section. According to the hydraulic lifting upside-down mounting method, the height of the required temporary lifting tool can be effectively reduced, consumed materials of the temporary lifting tool are reduced, the manufacturing time is shortened, the manufacturing workload is reduced, the construction cost is reduced, the later-period dismantling difficulty is reduced, the stability of the temporary lifting tool is correspondingly guaranteed after the height of the temporary lifting tool is reduced, and the construction risk is reduced and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of construction methods of equipment such as towers and tanks, and in particular to a hydraulic jacking and inversion method. Background technique [0002] The hydraulic jacking and inversion method is often used in the construction of large tanks and towers. The hydraulic jacking and inversion method refers to dividing the tank and tower from the top to the bottom with the bottom of the tank and tower as the reference plane. layer, build the top layer of the tank and tower first, then lift the top layer of the tank and tower upwards, assemble and connect the second layer on the lower side of the top layer of the tank and tower, and then place the completed The whole part is lifted upwards to assemble and connect the third layer, and the layer-by-layer assembly connection and jacking are carried out alternately, and finally the bottom layer connecting the tank and tower is built to complete the construction ...
