Design and Application of Avoiding Device of Attached Lifting Protection Platform
A new attached lifting protection platform what has a avoidance device is proposed to solve a problem that when the at-tached lifting protection platform work,it will be interference with other devices in the construction flow operation.The bottom truss of the platform adopts a"suspension bridge"structure,then analyze the technical difficulties of the structure,and put for-ward technical innovation points and construction points.Theoretical calculations,finite element analysis and experimental in-spection are used to verify the strength and the deflection of the bottom truss structure,which for confirm the safety performance of the space truss structure.The error between the calculated deflection value and the deflection test value is within 15%,and the maximum deflection value under the maximum construction load is less than 10mm,so the error and the maximum deflection value are in line with the current national standard requirements.The results of the calculation show that the avoidance device can effectively solve the problem of interference between the protective platform and other equipment and local protruding struc-tures during the lifting process,ensuring construction safety and improving construction efficiency.
