Abstract
The utility model relates to a cobble quick construction anchor rod which comprises a drill bit with ball teeth, an anchor rod, a connecting sleeve and a detachable connector, wherein, the drill bit is fixedly arranged on the anchor rod; an impactor which is fixedly connected with a main shaft of a driller is arranged on the tail end of the connector; the tail end of the anchor rod is welded with the connecting sleeve which is hinged with the connector. The utility model provides convenience for construction in disproportion soft and hard stratum, and can cancel the working procedure of beating and pulling casing pipes. A back impactor replaces a front impactor. Working efficiency is enhanced by 6 to 8 times, and construction cost is decreased by 50%.
Description
The utility model relates to and supports the anchor pole that side slope or foundation ditch use, especially with the cobble rapid construction anchor pole of a construction molding of drill bit.Be applicable to that railway, highway, reservoir moat slope reinforce pit shaft, the temporary lining of mine excavation supporting, house excavation of foundation pit.
Existing working anchor pole, mostly be indented bars or round steel, the sleeve pipe that the jumbolter utilization is repeatedly used repeatedly connects drill bit and preceding impactor at the sleeve pipe front end, the rotary impact power of impactor before utilizing, make sleeve pipe follow drill bit and progressively stretch into and treat strengthening stratum, arrive designated depth after, take out the drill bit and the preceding impactor that link together with drilling rod, put into anchor pole, after treating that anchor pole arrives assigned address, progressively extract sleeve pipe, cement injection mortar in the space between anchor pole and stratum.With the job practices more complicated that this anchor pole is used, pouring into an anchor pole need be through creeping into, places sleeve pipe and anchor pole is extracted sleeve pipe and drill bit, multiple working procedures such as preceding impactor, grouting, consumption manpower and time.When creep on construction stratum more rambunctious, for example run into ovum, the gravel stratum of soft or hard inequality, crooked, distortion that rotary drilling is easy to, place the sleeve pipe anchor pole like this, especially extracting drill bit and preceding impactor is to be difficult to take out in that distortion is crooked in creeping into, so just do not reach the purpose of repeatedly using drill bit and preceding impactor, and the price of preceding impactor is higher.
The purpose of this utility model is to propose a kind of pebble layer to use, rapid construction anchor pole that can a construction molding, at the anchor pole front end drill bit that is connected, be air-supply, dedusting and grouting channel in the anchor pole hollow tube, rear end and rig junction at anchor pole are provided with the back impactor, by this back impactor rotary drilling anchor pole, and take step-by-step movement mode construction molding grouted rock bolt.
Utility model is achieved in that a kind of cobble rapid construction anchor pole, comprise drill bit 2, anchor pole 3, adapter sleeve 6, it is characterized in that, the be connected tail end of drill bit 2 anchor poles 3 of dribbling tooth 1 of hollow bolt 3 front ends is welded to connect cover 6, the tube wall side face of the described adapter sleeve 6 moment of torsion pin-and-hole 7,71 that is crisscross arranged, the hinged dismountable connector 8 of the tail end of adapter sleeve, what the tail end setting of described connector 8 and back impactor were hinged is connected pin-and-hole 11.The circumferential surface of drill bit 2 is provided with and protrudes ball tooth 1, and the center is provided with the cooling that connects anchor pole and removes cinder hole 9, and evenly distributing along the drill bit periphery connects cooling slagging-off inclined hole 10.The anchor pole rear end is provided with the pulp retaining ring 4 and the slurry hole 5 of overflowing.The moment of torsion pin-and-hole 7,71 that is crisscross arranged on adapter sleeve 6 tube walls and can clogs.The front end of connector 8 is provided with moment of torsion pin-and-hole 81, and the rear end is provided with and connects pin-and-hole 11.
The utility model reduces working procedure, is the good tool of formation drilling of overcoming a difficulty, and reduces by 50% in single anchor pole operating expenses, and work efficiency improves 6～10 times.

Now further narrate structure of the present utility model in conjunction with the accompanying drawings.
Referring to Fig. 1-Fig. 3, form the utility model by drill bit 2, anchor pole 3, adapter sleeve 6, connector 8.The front end of anchor pole 3 and button bit 2 weld, and the drill bit of the spherical tooth 1 of band carbide alloy is provided with central ventilation cooling hole 9, evenly distribute inclined hole 10 so that dust is crept in cooling and removal along the drill bit periphery.The end of drill bit 2 and anchor pole welding.Anchor pole 3 is the hollow circular metal tube, sets firmly the pulp retaining ring 4 and the slurry hole 6 of overflowing in the rear end of anchor pole, and the effect of pulp retaining ring 4 is that the slurry hole 5 of overflowing when creeping into is avoided stopping up when overflowing slurry on overflow slurry hole 5, the pulp retaining ring and left the opening 41 of being convenient to the cement grout diffusion.
Anchor pole tail end and adapter sleeve 6 welding are provided with moment of torsion pin-and-hole 7 at adapter sleeve 6 and anchor pole welding section tube wall, and the rear end tube wall of adapter sleeve 6 is provided with moment of torsion pin-and-hole 71, and this moment of torsion pin-and-hole 71 is hinged with the moment of torsion pin-and-hole 81 of connector 8 front ends.Connector 8 is T-shaped, is provided with in the rear end of connector 8 to connect pin-and-hole 11, and is hinged with the back impactor that is installed on the rig main shaft at described connection pin-and-hole 11 places.
The connector 8 of waiting to dismantle and connecting with pin, both connector 8 and adapter sleeve 6 were behind the connecting pin at moment of torsion pin-and-hole 71,81 places, connector 8 is separated with adapter sleeve 6, on adapter sleeve 6, be solded into second anchor pole 3, weld at moment of torsion pin-and-hole 7,71 places to strengthen weld strength.
The cementation pipe waits to remove connector 8, and with after the moment of torsion pin-and-hole on the adapter sleeve 67, the 71 welding filling, from the cavity of anchor pole, with pressure injection and it is overflowed at slurry 5 places, hole of overflowing.
