Crane and lifting system

Abstract

The invention discloses a crane and a lifting system thereof. The lifting system is connected to a rack of the crane and used for lifting a heavy article, the lifting system comprises hoisting mechanisms, driving wheels, driven wheels, driving belts, a connection disc and an article picking device, the hoisting mechanisms and a guide cylinder are installed on and below the rack respectively, the hoisting mechanisms are in transmission connection with the driving wheels, the driven wheels are installed below the guide cylinder, each driving belt is provided with a first end and a second end, each first end bypasses the corresponding driving wheel from above the corresponding driving wheel and is fixed to the upper portion of the connection disc, each second end bypasses the corresponding driven wheel from below the corresponding driven wheel and is fixed to the lower portion of the connection disc, the article picking device is connected to the connection disc, and the hoisting mechanisms can drive the driving wheels to drive the driving belts and the article picking device to move up and down.

Description

technical field [0001] The invention relates to a hoisting system of a hoisting machine, in particular to a hoisting system with a special structure and a crane with the hoisting system. Background technique [0002] During the hoisting process of some special-purpose cranes, it is required to ensure that the load must be lifted vertically during the entire hoisting process, otherwise it will cause unnecessary damage to the load. Examples include marine cranes, or cranes that move and lift at the same time. During the operation of the crane, the load usually shakes, causing damage to the load. [0003] Existing cranes usually use vertical guidance to prevent the crane and the load from shaking from side to side during operation. However, although this method can ensure that the lifted load moves up and down vertically and avoids the shaking of the load, when the lifting speed of the crane is relatively high, the load and the pick-up device of the crane will move upward due...

AI Technical Summary

Problems solved by technology

However, although this method can ensure that the lifted load moves up and down vertically and avoids the shaking of the load, when the lifting speed of the crane is relatively high, the load and the pick-up device of the crane will move upward due to inertia when the crane stops, which is harmful to the crane. Generate a shock that affects the smooth operation of the crane

Or when this kind of lifting system is located on the sea or in the water, because of the shaking of the water, there will be an up and down shaking of the lifting load, which will affect the safety of the load
