Hoisting device for realizing integral continuous large-amplitude space angle rotation of heavy object and hoisting method thereof

Abstract

The invention discloses a hoisting device for realizing integral continuous large-amplitude space angle rotation of a heavy object. The hoisting device comprises a hoisting steering mechanism, a steel structure supporting system, a lifting jack group and a control system, the hoisting steering mechanism comprises an upper-end lifting appliance, a steering lifting appliance, a steel strand and a fixed-end anchorage device; the steel structure supporting system comprises a hoisting cross beam, a longitudinal beam and a portal frame; an even number of lifting jacks of the lifting jack group are divided into two groups and are respectively mounted on the two lifting cross beams; the upper ends of the steel strands penetrate through the lifting jacks and are anchored on the fixed end anchorage devices through the tensioning end anchorage devices; the upper-end lifting appliance is connected with the steering lifting appliance in a pin shaft manner; the steering lifting appliance is in pin joint with a lifting lug on a heavy object; according to the hoisting method for achieving integral continuous large-amplitude space angle rotation of the heavy object, the lifting lugs are arranged on the outer side of the gravity center of the heavy object structure, integral continuous large-amplitude space angle rotation of the heavy object is achieved by changing the horizontal projection distance between the lifting lugs of the heavy object and the height of a sling between the lifting lugs and a lifting point, and the method is easy and convenient to operate and good in technical effect.

Description

technical field [0001] The invention relates to a heavy object hoisting device and a hoisting method, in particular to a hoisting device and a hoisting method which can realize the continuous and large-scale spatial angle rotation of the heavy object as a whole. Background technique [0002] In construction sites, heavy objects are often hoisted. At present, many heavy object hoisting devices and hoisting methods only shift the position of the heavy objects in the vertical direction, and do not involve the situation that the heavy objects are on the empty ground or support structure. Under the premise of not changing the hoisting point, the spatial angle rotation of the heavy object is carried out; since more and more heavy objects are irregular in shape, and there will be a certain spatial angle in the installation position, the adjustment range of the conventional hoisting angle is limited. It is unable to meet the needs of rapid and continuous large-scale spatial angle ro...

AI Technical Summary

Problems solved by technology

[0004] 1. The hoisting method requires the use of additional hoisting equipment hooks, and it is difficult to achieve super high and super heavy hoisting due to load and site constraints;

[0005] 2. The hoisting equipment hook 1 is integrally hoisted, and the heavy object is lifted to transfer the load to the sling and the hook. The flexible sling 3 and the hook 1 are easily shaken due to the influence of the environment and wind load, and the hoisting stability is poor;

[0006] 3. The distance between the jacks 5 is fixed, and the attitude of the structural weight needs to be adjusted in advance, and the attitude adjustment in the air cannot be realized during the lifting process; therefore, it cannot meet the different needs of construction
