Underground wire point suspension device

Technical Field

The utility model relates to a wire point hangs technical field, specifically is a wire point linkage in pit.

Background

With the development of society and the increase of population, people have higher and higher demands on mineral resources, roads and traffic. In these projects, for example, mining, excavation of roadways in subway construction, and tunnel penetration, the method is applied to control of the measurement of the wire in the measurement, so as to determine the construction direction.

At present, the traditional method for arranging measurement control points in mines is to arrange measurement lead point marks on a stable top plate of a mine roadway, and a plumb ball line is adopted to hang a plumb ball, so that construction and instrument point centering are facilitated, and meanwhile, underground personnel walking and equipment operation can be prevented from damaging the measurement lead points. In actual production process, because the particularity of production environment in the pit, consider the safety and the protection wire point of passing pedestrian, consequently current linkage can not use high strength tensile plumb bob line to hang plumb bob, avoid cutting the pedestrian or receive the brute force to pull and cause the wire point to damage, but adopt the lower plumb bob line of intensity to hang plumb bob and lead to passing haulage vehicle in the pit, often will hang plumb bob line to tear apart, need two people's cooperation to ascend a height wiring after tearing apart at least, not only wiring inefficiency, there is high altitude construction's potential safety hazard still.
