A hydraulic dynamic compensation device for butt joint of large steel structure

Abstract

The utility model discloses a kind of hydraulic dynamic compensation devices for butt joint of large steel structure, the system includes detachable oil cylinder compensation device installed on SPMT flat car, the device is fixed by multiple composite locking structures, limit transverse and longitudinal displacement;Composite locking structure is reliably connected with transport car boundary beam by clamping plate, friction lining and sleeve plate slip structure.Each locking structure is installed hydraulic oil cylinder, its top is equipped with universal ball hinge flange base and module connecting plate welding, realize omnidirectional pose compensation, and reserve swing space to absorb error and release torsional stress.In complex working conditions such as cable trench or ground subsidence, the device can quickly adjust module posture, avoid shutdown pad, improve assembly accuracy to ±0.5mm, efficiency is improved by about 90%, and has the advantages of quick disassembly, reduce stress concentration, prolong fatigue life, suitable for large ocean engineering, shipbuilding and other heavy equipment high-precision folding operation.
