Chain type lifting device

Abstract

The invention discloses a chain type lifting device which comprises a rack, a lifting mechanism, a fixing plate and a driving mechanism, the lifting mechanism comprises a driving shaft, a driven shaft, driving chain wheels, driven chain wheels, chains and a hopper, the driving shaft and the driven shaft are rotationally connected with the rack, the two driving chain wheels are fixedly arranged on the driving shaft in a sleeving mode at intervals, the two driven chain wheels are arranged on the driven shaft in a sleeving mode at intervals, one driven chain wheel is fixedly connected with the driven shaft, the other driven chain wheel is rotationally connected with the driven shaft, the chains are meshed with the driving chain wheel and the driven chain wheel, the two ends of the hopper are connected with the two chains respectively, the two ends of the fixing plate are rotationally connected with the driving shaft and the driven shaft correspondingly; and the driving mechanism is arranged on the rack, is connected with one end of the driving shaft and drives the driving shaft to rotate, so that the chains move to drive the hopper to lift. By the adoption of the chain type lifting device, vibration in operation is reduced, noise is low, abrasion of the chain wheels and the chains is small, the service life of the chains is long, and the replacement frequency is reduced.

Description

technical field [0001] The invention relates to the field of lifting transportation equipment, in particular to a chain lifting device. Background technique [0002] Chain hoist, also known as plate chain hoist, is a kind of conveying equipment that uses the hopper fixed on the chain to move around the head and tail sprocket to realize material lifting. The moving parts are wound around the upper drive sprocket and On the lower direction-changing sprocket, under the action of the driving device, the driving sprocket drives the traction member and the hopper to make a circular motion, and the material is fed into each hopper from the lower feeding port. When the material is lifted to the upper sprocket, the Under the action of gravity and centrifugal force, it is discharged from the discharge port. Chain hoist is the most widely used vertical lifting equipment, it is used to lift various bulk materials, such as: ore, coal, cement, cement clinker, etc. [0003] The head driv...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention proposes a chain hoist to solve the problem that the existing chain hoist proposed in the background art generally suffers from violent vibrations, loud noises, sprockets and The chain is easy to wear and tear, and the chain is easy to break, resulting in a high frequency of replacement
