Embodiment Construction

[0029] The structure of the hoist of the present invention is shown in the accompanying drawings. One end of the driving steel rope (single-rope winding drive or multi-rope winding drive) is fixedly connected to the driving drum of the winding hoist according to the upper and lower ropes respectively. The other end of rope is articulated with the hoisting container through the upper sky wheel set (or balance wheel). The other end of going out rope is articulated with another hoisting container through lower sky wheel group around. The two ends of the tail rope are connected with the lower parts of the two hoisting containers respectively. The even-numbered suspension steel ropes are placed on the upper sky wheel group (or balance wheel), and its two ends are respectively articulated with the steel rope connectors of the steel rope tension full-automatic balancing devices on the two hoisting containers. The sky wheel set (or balance wheel) bears the whole weight of the hoistin...

Abstract

A multi-cable suspended lift with tail cable for balancing is composed of drive drum, overhead pulley set for bearing all load of suspending steel cable and lift container, driving steel cable, lift contain and tail cable. The active load of driving steel cable and lift container is borne by drive drum.

Description

technical field [0001] The invention relates to an industrial and mining hoisting device, in particular to a multi-rope suspension tail rope balance type hoist with large load, high safety factor and long service life. technical background [0002] Shaft hoisting is the throat connecting the well and the underground, and it is responsible for the vertical lifting tasks of ore, waste rock personnel, materials and equipment. There are many factors influencing the selection of the shaft hoisting system, such as mine scale, transportation mode, mine ventilation, specific hoisting tasks (main shaft, auxiliary shaft or mixed hoisting), development depth, etc. Therefore, the lifting system generally needs to be determined after comparing multiple schemes. The selection of lifting equipment and the operation of the lifting system are two key factors in the process of program determination. This is also the focus of many years of research on the applicable conditions and economics ...
