Abstract
The utility model discloses a drilling type anchor rod which comprises a drill bit and a hollow drilling rod fixedly connected to the tail end of the drill bit. The drill bit is provided with a guniting hole communicated with the outside and a cavity in the drilling rod. The outer wall of the drill bit is connected with an anchor ring in a sleeved mode, and at least two anchor cables are welded to the anchor ring. The drill bit comprises a drill bit body and a drill piece installed on the drill bit body. The drill bit body is hinged to the drill piece. The drill bit further comprises a limiting part fixedly connected to the tail end of the drill bit body and used for limiting the rotating angle of the drill piece. In addition, the width of the drill bit body and the width of the drill piece are smaller than the inner diameter of the anchor ring. The drilling type anchor rod has the advantages that the effect of the drill bit of the anchor rod in the drilling process is ensured, the technological defect that a drill bit of a conventional anchor rod cannot be utilized repeatedly is overcome, and construction cost is greatly reduced.

As shown in Figure 1-2, existing anchor pole in work progress, is directly stayed station by drill bit conventionally, and drilling rod partly exits.The great like this waste that causes drill bit.
Utility model content
Cannot nonexpondable technological deficiency for solving the drill bit of anchor pole in prior art, the utility model is designed a kind of drilling type anchor pole, has realized the object that drill bit is repeatedly used, and has also avoided cannot reusing because of drill bit the economic loss causing simultaneously.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of drilling type anchor pole, comprise drill bit and the hollow drill that is fixed in drill bit tail end, on drill bit, offer and be communicated with gunniting hole extraneous and drilling rod internal cavity, at least two anchor cables of welding on drill bit outer wall socket anchor ring and anchor ring, drill bit comprises drill body and is arranged on the brill sheet on drill body, and drill body is with to bore sheet hinged; Drill bit also comprise be fixed in drill body tail end for limiting the locating part that bores the sheet anglec of rotation; And the width of drill body and brill sheet is all less than the internal diameter of anchor ring.
Preferably, the longitudinal section of gunniting hole is L shaped.
Further, drill body and locating part are integral type structure.Drill body is that integral type structure can be strengthened the fastness that drill body is connected with locating part with locating part.
Preferably, locating part is a multidiameter, and this multidiameter comprises the limit shaft being connected with drill body and the connecting axle being connected with drilling rod, and wherein the external diameter of limit shaft is less than the internal diameter of anchor ring, and the external diameter of connecting axle is greater than the internal diameter of anchor ring.Drill bit is in drilling process, and due to above-mentioned size restrictions, anchor ring is fixed on limit shaft tail end and is positioned at connecting axle front end.
Preferably, drill body is hinged with brill sheet by rotating shaft, and wherein, boring sheet is two, is arranged on respectively the two ends of rotating shaft.Be symmetrical arranged like this brill sheet, be conducive to guarantee the balance of drill bit in drilling process.
Preferably, equal embedded alloy sheet on the inclination sword of drill bit and brill sheet.Alloy sheet adopts hard metal tip, the durability that can strengthen drill bit and bore sheet, and be also convenient for changing after alloy sheet damage.
The beneficial effects of the utility model are: the effect of the drill bit that has guaranteed anchor pole in drilling process, and the technological deficiency of having avoided the drill bit of conventional anchor pole to reuse, greatly reduce construction cost.
