Three-pivot chute lifting appliance for ship loader

Abstract

The invention relates to a three-pivot chute lifting appliance for drawing a ship loader. The lifting appliance mainly comprises a motor, a brake, a speed reducer and a winding drum which are assembled into a whole and arranged on a chute platform, and is characterized in that: the winding drum is provided with a first group of guide pulleys, a second group of guide pulleys and a third group of guide pulleys; the first group of guide pulleys draw a first steel wire rope, the second group of guide pulleys draw a second steel wire rope, and the third group of guide pulleys draw a third steel wire rope; and the first steel wire rope, the second steel wire rope and the third steel wire rope are respectively connected with a telescopic chute. The telescopic chute is uniformly provided with connection points of the three steel wire ropes at 120 degrees, so the telescopic chute can be effectively prevented from irregularly swinging and stably does up and down free telescopic movement; friction among chutes can be reduced and the chutes are prevented from being locked; and the three-pivot chute lifting appliance has the advantages of safe and reliable use, convenient maintenance, and capabilities of prolonging the service life of the telescopic chute and improving production efficiency.

Description

technical field [0001] The invention relates to a three-fulcrum chute lifting device of a ship loader, in particular to the telescoping of the chute of the ship loader, and belongs to the technical field of port engineering machinery. Background technique [0002] With the progress of global economic integration, the current port handling equipment is developing in the direction of high efficiency and large scale. As an important part of the bulk cargo loading process, the ship loader can operate safely, reliably and economically, which is of great significance to the development of port production and the improvement of economic benefits. The chute is the last pass through which the goods enter the cabin from the dock yard, through the belt system, ship loader equipment, and finally into the cabin; if there is a problem with the chute, the entire system will be shut down. At present, the chute of the ship loader is a telescopic chute, and the chute is stretched by two stee...

AI Technical Summary

Problems solved by technology

At present, the chute of the ship loader is a telescopic chute, and the chute is stretched by two steel wire ropes. During use, if the chute is tilted or the force is uneven, the friction between the chute will increase, and slippage will easily occur. The cylinder is stuck, which greatly affects the service life and performance of the cylinder
