CONSTRUCTIVE IMPROVEMENTS OF CABLE TENSIONING MECHANISM FOR DEC DEVICES
Abstract
The balancing devices in cable tension, DEC's, linking the extraction vessel (SKIP) and cables binding devices, DLCпїЅs, and are designed to equalize the tension in cables of extraction plant (multicable). The paper presents a new solution design of the screw-nut mechanism of initial tension cable for the uniformity tension and horizontal positioning of the rocking mechanism. The extraction vessels cables are attached to those by means of binding devices and equipment. Binding devices and equipment should be safe in operation and fatigue resistant, lightweight and of small dimensions, protecting cables and being easily maintained. Equipments have different structures depending on the nature of the hoisting installations and of the extraction vessels for which they are used. They can have fixed length, in general, in mono-cable installation and adjustable length in multi-cable installations. The new constructive solution achieved: improving the coefficient of use of the material, reducing labour consumption, tools and electricity, eliminating mechanical deformations at the milling, reducing manufacturing time and cost.
