Problems solved by technology

[0002] Many large-scale equipment and steel structures need to be lifted with the help of hoists when installing existing large-scale equipment and steel structures; Most of the lifts in China are single-point lifting, which cannot guarantee that the object will remain in a stable state or a designated position after lifting, which makes it difficult to install or adjust after lifting; and the single-point lifting is used for a long time or overloaded, which will affect the lifting. The service life of the machine; not only wasting time and manpower, but also reducing work efficiency

Abstract

The invention relates to the technical field of lifting machines, in particular to a flexible multipoint concentrated lifting device. The flexible multipoint concentrated lifting device comprises a round frame, lifting units arranged on the round frame, a winding and unwinding device arranged on one side of the round frame and a transmission device arranged between the round frame and the winding and unwinding device, wherein the winding and unwinding device comprises a winding drum, frame bodies, speed reducers and brake devices; shafts at the two ends of the winding drum penetrate through the frame bodies and then are in bearing connection with the frame bodies; one shaft of each speed reducer is fixedly connected with a shaft of the winding drum; and each brake device is mounted on one side of the corresponding frame body. Multipoint lifting is adopted, it is ensured that downward force of objects can be balanced, and rope breakage is not prone to being caused; outer ring frames are used for lifting the objects, and it is guaranteed that the state and position of the lifted objects are not easy to change; balancing weights can be used for reducing the pressure of motors and is not easy to damage; and electric push rods can be used for ensuring dead locking after lifting, so that danger is avoided.

Description

technical field [0001] The invention relates to the technical field of hoists, in particular to a flexible multi-point centralized hoisting device. Background technique [0002] Many large-scale equipment and steel structures need to be lifted with the help of hoists when installing existing large-scale equipment and steel structures; Most of the lifts in the world are single-point lifts. After lifting, it is impossible to ensure that the object remains in a stable state or in a designated position, which makes it difficult to install or adjust after lifting. Moreover, single-point lifts are used for a long time or overloaded, which will affect the lifting. The service life of the machine; not only wasting time and manpower, but also reducing work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flexible multi-point centralized lifting device for the above-mentioned technical deficiencies, which ado...
