High-angle rotation wire feeding device of bucket wheel machine

Abstract

The invention relates to a high-angle rotation wire feeding device of a bucket wheel machine, which is installed a rotation central line at the upper section of a vertical column of the bucket wheel machine, is positioned above a pitching mechanism, and is suspended on a vertical column pull rod through welding. The upper end of the high-angle rotation wire feeding device of the bucket wheel machine is provided with a hoisting shaft which is connected to the vertical column pull rod through a screw rod and can perform small-amplitude pendulum motions along the rotation central line of the bucket wheel machine; the middle of the high-angle rotation wire feeding device of the bucket wheel machine is provided with an inverted T-shaped rotary shaft which is fixed on a hoisting shaft through a pressing plate, and can rotate for 360 degrees around the rotation central line; the lower end of the high-angle rotation wire feeding device of the bucket wheel machine is provided with an arch-back-shaped hoisting frame; the upper end of the hoisting frame is clamped into the rotary shaft, and the annular forms of cable wires penetrate through the arch back part of the hoisting frame; the arch back part forms a cylinder channel by dual-arc-shaped tile-shaped steel plates, and upper and lower tile-shaped steel plates are fixed by bolts; cable wires are arranged on the lower tile-shaped steel plate in a lapping manner; and the upper tile-shaped steel plate is covered on cable wires of the lower tile-shaped steel plate in a lapped manner. An electric cable rotary cylinder is arranged on a tail vehicle, and cable wires run through the vertical column through the tail vehicle, and directly enter a cab through a wire feeding device on the rotation central line of the vertical column, and under the condition, the rotation angle is increased to + / -165 degrees.

Description

technical field [0001] The present invention is a divisional application of the Chinese patent "a new on-line method and device for a bucket wheel machine", the application date is August 29, 2011, and the application number is 201110250325.1. The invention relates to a new on-line method and device for a bucket wheel machine, in particular to a large-angle rotary on-line device for a bucket wheel machine, which belongs to the field of bulk material piles and fetching equipment in operation transportation. Background technique [0002] Bucket Wheel Conveyor is a large-scale bulk material conveying equipment widely used in ports, electric power, coal, metallurgy and other industries. It is divided into stacker and reclaimer according to its function. According to the form of the running device, the bucket wheel machine can be divided into: crawler type, tire type and track type, among which the track type is the most widely used structural form at present. Take the material....

AI Technical Summary

Problems solved by technology

There are three disadvantages in the traditional rotary on-line method: First, there are central hoppers on the door seat of the bucket wheel stacker and reclaimer and the middle of the rotary platform, and materials pass through the hopper. In order to prevent the cables from being damaged by materials, there should be steel pipes on the outside of the cable on the center line. Protection, the steel pipe in the center of the hopper greatly affects the flow capacity of materials passing through the hopper, and is prone to material blocking; second, when the rotation angle is large, the torsion angle and stretching length of the cable are large, and the cable is prone to fatigue damage; It is the twisting movement of the cable in the steel pipe, and the cable has a certain amount of friction with the inner wall of the steel pipe. After a long working time, the cable will be worn out. Therefore, the traditional center on-line device is not ideal for the rotary on-line of the bucket wheel stacker and reclaimer with a large rotation angle.
