Background
In the mine construction engineering, after a mine hoist and a sinking and stabilizing vehicle are installed, rope winding operation is carried out, and the traditional method comprises the following steps: the wire rope disc and the winch are distributed on two sides of the sinking derrick, a wire rope on the wire rope disc is pulled to pass through a head sheave on the derrick and then is connected to a winch drum, the wire rope is wound on the winch drum through the power of the winch, and the number of winding layers is generally 2-6 layers according to the depth of a shaft and the rope containing amount of the winch on the drum. The biggest problem of the rope winding mode is that no additional tension force is added when the steel wire rope is wound, and the rope is not tightly wound between the ropes and between layers, so that the phenomena of rope biting and rope loosening are formed in the subsequent load-bearing suspension operation process, namely, the steel wire rope on the upper layer is extruded into the lower layer, and even if iron bars are added between the layers, the steel wire rope cannot be fortunate when the tension force of the steel wire rope is too large. Under the condition, the steel wire rope is completely lowered to the bottom of the well and is stressed and wound again by the dead weight of the steel wire rope, the process generally needs 3-5 times, the normal work of the steel wire rope can be guaranteed until the end of the project, and the project progress, safety and cost are greatly influenced.
How to increase the additional tension of the steel wire rope, field constructors also want to have a plurality of methods, namely pulling by using a rigging and pulling by using an engineering truck, and finally the effect is poor, so that no good method exists. The device of the invention well solves the problems and winds the rope once stressed.
