Global automatically controlled hydraulic jacking device and jacking method thereof

Abstract

This invention relates to a full range self-controllable hydraulic pressure lift-up device package and lift-up method; wherein, the device comprises hydraulic pressure system and autonomous system; said hydraulic pressure system includes hydraulic pressure station and hydraulic pressure hydro-cylinder which sets lift-up bracket on the top; said station is connected with hydro-cylinder through lift-up oil line and drop one separately; said autonomous system comprises industrial controlling computer, displacement scale transducer, speed-sensitive switch valve and output control housing; said method comprises following steps: a)starting up the device; b)setting the lift-up height of object; c) balancing the lift-up height of individual hydraulic pressure hydro-cylinder to lift up the object to the setting position in-phase. The invention is suitable to fix and construct oilcan with individual specification.

Description

technical field [0001] The invention relates to the technical field of installation of large metal oil tanks, in particular to a full-range self-controlled hydraulic jacking device. Background technique [0002] In the installation process of large vertical vaulted oil tanks, the typical jacking process that is widely used at present is the inflatable jacking and flipping process. The safety and reliability of this process are relatively poor, and it is difficult to ensure the quality of wall plate assembly and welding. The specific performance is: (1) During the process of inflation and jacking, the installation quality of the sealing device, guiding and stabilizing device and limit device must be strictly controlled. The operating procedures are complicated, which may easily lead to major safety or quality accidents; (2) When the hoarding is performed, due to the large tightening force of the door closing panel, the frictional resistance generated ...

AI Technical Summary

Problems solved by technology

However, there are still some defects in this process: since the synchronization problem of "full-range jacking" cannot be solved, only the "step-by-step hydraulic jacking process" can be used, that is, the work of "hydraulic loosening-climbing-lifting-falling" principle

This kind of process must be lifted gradually, and it cannot be lifted in place at one time. It needs repeated jacking to meet the construction requirements, and the single-step jacking stroke is only 172mm at most, so the operation is very complicated and the work efficiency is low.
