Problems solved by technology

[0002] The currently known multi-point synchronous jacking devices and methods are mainly aimed at jacking construction, and have insufficient consideration for high-precision synchronous lowering under heavy load conditions, and generally require that the forces on each jack be basically balanced, and cannot fully adapt to severe deviations. High-precision multi-point synchronous lifting requirements under working conditions such as load and large variable load

Embodiment Construction

[0031] Below in conjunction with accompanying drawing and embodiment (large miter door lifting), the present invention is described in further detail, but the scope of implementation of the present invention, the mode are not limited thereto.

[0032] Refer to attached Figure 4 , this embodiment is four-point synchronization, and the large-scale miter gate of the Gezhouba ship lock is required to be lifted. The gate is 33.82 meters high, 19.7 meters wide, 2.7 meters thick, and the gate weighs 600 tons; the gate body is a flat beam structure with a panel on one side , The positions of the four jacking points have been limited, and the unbalanced load is serious. It is required to be lifted to a certain height in situ, and to fall back to the original position after the relevant parts are repaired, and the height difference of each point shall not be greater than 0.5mm.

[0033] Refer to attached figure 1 , 2 , 3, a kind of multi-point synchronous lifting device of the prese...

Description

technical field [0001] The invention relates to the technical field of lifting and construction of large components, in particular to a novel high-precision multi-point synchronous lifting device and a lifting method thereof. Background technique [0002] The currently known multi-point synchronous jacking devices and methods are mainly aimed at jacking construction, and have insufficient consideration for high-precision synchronous lowering under heavy load conditions, and generally require that the forces on each jack be basically balanced, and cannot fully adapt to severe deviations. High-precision multi-point synchronous lifting requirements under working conditions such as load and large variable load. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides a high-precision multi-point synchronous lifting device and its lifting method that can automatically adapt to severe unbalanced loads and...
