Abstract
A safe and efficient false roof-free supporting tool is an integral component consisting of a clamping end, a handle body and a working end, wherein one end of the handle body is the working end, the other end of the handle body is the clamping end, the cross section of the clamping end is regular hexagon, the working end is hollow, the clamping end is designed to be a hexagonal steel structure matched with a drill bit shank sleeve of a pneumatic rock drill, and the hollow part of the working end is designed to be a sleeve structure matched with a bolt at a threaded end of an anchor rod. The utility model solves the problems of higher risk and low operation efficiency of the traditional method in the process of installing the anchor rod and fastening the anchor rod nut in underground mining false roof-free support, and reduces the safety risk in the traditional operation process to the maximum extent; the operation cost is effectively controlled.
Description
Technical Field
The utility model relates to an exploitation technical field in the pit specifically indicates a safe efficient does not have false top supporting tool.
Background
In the process of installing an anchor rod and fastening an anchor rod nut in underground mining non-false top supporting operation, the traditional method is that an operator drives the anchor rod into a hoisting hole from the end part of the anchor rod by using a hand hammer tool by means of an ascending platform, and the nut is fastened manually by using a wrench tool. The conditions that the operation points are higher and the operation of personnel is time-consuming and labor-consuming exist in part of positions in the operation process; meanwhile, the distance between the operating personnel and the operating point is close, and certain safety risk exists.
SUMMERY OF THE UTILITY MODEL
To sum up, the utility model aims at providing a safe efficient does not have false top and struts instrument, this instrument aims at solving the operation process and prepares loaded down with trivial details, and safe risk is great, the not high scheduling problem of operating efficiency.
The utility model provides a technical scheme that its technical problem adopted is:
a safe and efficient false roof-free supporting tool is an integral component consisting of a clamping end, a handle body and a working end, wherein one end of the handle body is the working end, the other end of the handle body is the clamping end, the cross section of the clamping end is in a regular hexagon shape, and the working end is hollow.
The clamping end is designed into a six-edge steel structure matched with a drill bit sleeve of the pneumatic rock drill.
The hollow part of the working end is designed into a sleeve structure matched with the bolt at the threaded end of the anchor rod.
The shape and the size of the clamping end are matched with a drill rod tail sleeve of the pneumatic rock drill; the sleeve structure of the working end matched with the bolt at the threaded end of the anchor rod is not limited by the length of the threaded end of the anchor rod when the bolt is fastened, and enough axial and radial sizes are reserved in the center of the working end; the length of the handle body is the shortest length required by the anchor rod, and the safe operation distance is considered.
The utility model has the advantages that:
the safety of underground mining false roof-free support operators is fully guaranteed, and the safety risk in the traditional operation process is reduced to the greatest extent; the operation procedure is simpler and more convenient than the traditional operation, and the preparation work before the operation is simplified; part of heavy manual operation is replaced, the labor intensity of personnel is effectively reduced, and the operation cost is effectively controlled; the method is applied to underground mining of West mine F17 in the third mining area of Jinchuan group Limited company, and achieves the expected effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
FIG. 2 is a schematic view of A-A in FIG. 1.
FIG. 3 is a schematic view of B-B in FIG. 1.
Detailed Description
The invention will be further explained with reference to the drawings:
as shown in fig. 1, a safe and efficient false roof-free supporting tool is an integral component composed of a clamping end 1, a handle body 2 and a working end 3, wherein one end of the handle body 2 is the working end 3, the other end of the handle body is the clamping end 1, the cross section of the clamping end 1 is a regular hexagon, and the working end 3 is hollow.
The clamping end 1 is designed into a six-edge steel structure matched with a drill bit sleeve of the pneumatic rock drill.
The hollow part of the working end 3 is designed into a sleeve structure matched with a bolt at the threaded end of the anchor rod.
Examples
When the pneumatic rock drill is used, the tool clamping end 1 is installed into a drill bit sleeve of the pneumatic rock drill to be fixed, the working end 3 is pushed to the head of the anchor rod after the anchor rod is brought into the mesh pressing plate and the nut, the anchor rod is pushed into a hanging hole by utilizing intermittent impact and air leg support compensation of the pneumatic rock drill, and then the anchor rod bolt is automatically screwed.
