Turning device and turning method for super-heavy and oversized article

Abstract

The invention relates to a turning device and turning method for a super-heavy and oversized article. The turning device is formed by at least four groups of device units. Each group of device units comprises a lifter, a hydraulic push rod, a pushing support, a piston shoe and a slippage beam, wherein the pushing support and the piston shoe are respectively arranged on the slippage beam, the front end of the pushing support is connected with one end of the hydraulic push rod, the other end of the hydraulic push rod is hinged to the piston shoe, a lug plate is hinged to the piston shoe, the lug plate and the rear end of the article to be turned are integrally fixed, the lifter is arranged on a fixing structure above the article to be turned, and the lower end of a traction rope of the lifter is connected with a lifting lug fixed at the front end of the article to be turned. At least 2*2 groups of device units are utilized, the two device units are used for drawing the article, the other two device units are used for pushing forwards step by step, and a similar circulation process can be repeated many times to turn the article in a horizontal state to a vertical state. The turning device for the super-heavy and oversized article is low in manufacturing cost, convenient to transport and carry, convenient and flexible to operate, capable of improving construction progress and capable of reducing construction cost.

Description

technical field [0001] The invention relates to an overturning construction method for super-heavy and super-large objects, in particular to an overturning device and method for super-heavy and super-large objects. Background technique [0002] At present, the following two schemes are usually adopted for the overturning construction of super-heavy and super-large objects: one is to use multiple or one hoisting equipment to complete the overturning operation of changing the position or direction of super-heavy and super-large objects. In the space environment of a platform or a hoisting equipment station, it is impossible to complete the flipping operation of the object's position or direction; the other is to use a winch or a chain hoist to return to the pulley many times to meet the requirements of changing the position or direction of super-heavy and super-large objects. Overturning operation, this solution is limited by the height of the space environment, construction s...

[0002] At present, the following two schemes are usually adopted for the overturning construction of super-heavy and super-large objects: one is to use multiple or one hoisting equipment to complete the overturning operation of changing the position or direction of super-heavy and super-large objects. In the space environment of a platform or a hoisting equipment station, it is impossible to complete the flipping operation of the object's position or direction; the other is to use a winch or a chain hoist to return to the pulley many times to meet the requirements of changing the position or direction of super-heavy and super-large objects. Overturning operation, this solution is limited by the height of the space environment, construction support points and designated environmental location factors in some specific environments, and cannot meet the construction requirements; especially for super-heavy and super-large objects that only bear two or a few points of tension at the end When the deformation, deflection and synchronization of the object cannot be effectively controlled, the safety and reliability of the construction cannot be guaranteed.
