Description
Technical Field
The invention relates to the technical field of mine equipment maintenance and installation, in particular to a flat tail rope replacing device of a single lifting system and a replacing method thereof.
Background
The large and medium-sized coal mines at home and abroad are provided with a main shaft and an auxiliary shaft lifting system, and the function of balancing the tail rope is crucial and the whole lifting system can be balanced. Therefore, the replacement of the pigtail rope of the mine hoisting system is the most important task in the mine shutdown maintenance.
At present, the replacement method of the flat tail rope of each main mine well and each auxiliary mine well mainly adopts a laying mode that one side of a lifting container is provided with a new rope, and the other side of the lifting container is used for throwing an old rope for construction (the auxiliary mine well is directly constructed at a ingate at the bottom of the well). By adopting the mode of replacing the tail rope, after the wide cage is provided with the new tail rope in place, the step of manufacturing the new tail rope suspension on the narrow cage side needs to turn the new tail rope on the rope reel on the shaft outlet side over the tail rope stop beam under the shaft, and then the new tail rope suspension work can be performed after the position of the narrow cage side. This is convenient for the double-lifting system to realize rope-turning work. However, for single-lift systems (such as Zhu Jikuang gangue well, zhang Jikuang main well, zhang Beikuang main well, pan Yi mine secondary well and other single lifts, zhang Jikuang secondary well mixed lift, zhang Ji west wind well mixed lift, and bridge-building mine secondary well mixed lift system), reversing tail rope and making new tail rope suspension are tedious and complicated construction steps. In the conventional single lifting system, two slow twists A, B need to be arranged at a wellhead when a tail rope is turned over and a new tail rope is hung, wherein the slow twist A is used for placing the new tail rope at the wellhead, and the slow twist B is used for penetrating through a tail rope stop beam to connect the head of the new tail rope which is slowly twisted A, so that the steps of turning over the tail rope and hanging the new tail rope can be realized.
However, the above method has the following disadvantages: 1. the labor intensity is high, new tail ropes are required to be manually discharged from a tail rope disc, then tail rope heads are pulled to a wellhead, then the tail ropes are slowly twisted and conveyed to tail rope blocking beams by using a twisting machine A, and then the tail ropes are slowly twisted and connected by using a twisting machine B, so that rope turning is realized; 2. in the rope turning process, the tail rope is easily turned (twisted and deformed), so that the service life of the tail rope is shortened, and the tail rope is reworked; 3. the safety is poor in the process of directly conveying a new tail rope to the tail rope stop beam by using the A slow twist, so that the new tail rope at a well mouth can easily fall into a shaft at one time, and accidents are caused; 4. the method has low rope turning efficiency and greatly restricts the construction period.
Therefore, it is important to provide a flattail rope replacing device of a single lifting system and a replacing method thereof, which are simple to operate and high in safety.
