Description
Technical Field
The invention relates to the field of anchor cable installation equipment, in particular to an auxiliary conveying device for an anchor cable under a mine.
Background
The phenomenon that the bottom plate of the roadway is raised upwards is called floor heave because the top bottom plate of the roadway and the rock mass at two sides are deformed and displaced into the roadway under the influence of the mining engineering. Floor heave increases the moving amount between the top plate and the bottom plate of the roadway, reduces the section size of the roadway, and prevents normal transportation, passing and ventilation. In order to solve the floor heave problem, the roadway floor needs to be supported by adopting a mode of installing a floor anchor cable, and the roadway floor mainly comprises 2 working procedures of floor pore-forming and anchor cable anchoring. After punching is carried out on the bottom plate of the soft rock roadway, broken stone accumulation is easy to occur on the hole wall and the hole bottom, the anchor cable cannot be directly installed in the anchor cable hole deeply, the anchor cable can be installed only by drilling and slag removal, and a large amount of labor and time cost are consumed. On the other hand, after the anchor cable is inserted, grouting is needed to be carried out in the anchor cable hole so as to fill and strengthen the anchor cable, and as slurry is needed to be sequentially injected with slurry A and slurry B during grouting, the slurry A and the slurry B are stirred and mixed to play a solidification effect. In the existing construction process, a small-range action is usually carried out by manually rotating the anchor cable, and meanwhile auxiliary mixing is carried out by means of slurry self-flowing, because the installation length of the anchor cable can reach 4 to 8 meters, the stirring range is difficult to expand by manual operation alone, the labor cost is high, the stirring effect is poor, and the stability and the reliability of the installation of the anchor cable cannot be guaranteed.
