Description
Technical Field
The utility model relates to special equipment for replacing a tail rope in a mine, in particular to a rope threading and guiding device suitable for replacing a flat tail rope of a mine hoisting system, and belongs to the technical field of mine equipment.
Background
In a mine hoisting system, in order to balance the weight of a hoisting steel wire rope (also called a first rope), a tail rope is usually selected and matched, the tail rope does not bear hoisting load, but occupies a very important position in the hoisting system, and if the tail rope has a problem, the normal work of the hoisting system can be influenced, so that production stop or even greater loss is caused. The flat tail rope, i.e. the flat steel wire rope, is a flat ribbon-shaped flat steel wire rope formed by weaving a certain number of strands (or sub-ropes) arranged in parallel on a plane by weft ropes, and is widely applied to a mine hoisting system due to the characteristics of absolute non-rotation and large weight per unit length.
After the mine is put into production, part of the hoisting facilities and shaft facilities of the mine hoisting system need to be replaced periodically to meet the requirement of safe production. Taking a balanced flat tail rope specially used for lifting materials as an example, when the ratio of the broken wire section area to the total steel wire section area in a lay length reaches 10%, the rope must be replaced immediately no matter how many broken wires are or whether the diameter of the rope changes, when the corrosion of the steel wire rope is serious, or pits are formed by pitting, or the outer layer steel wire is loose.
