Description
Technical field
The invention belongs to the bolt support technology field of mining engineering, particularly a kind of small-bore hard rock Counterboring apparatus.
Background technology
Owing to can significantly improving supporting effect, reduce costs, reduce labor intensity, improve operating environment, guarantee safety in production and being conducive to the advantages such as the quick propelling of face, bolt support technology has become one of supporting method of extensive use in mining engineering.Along with China's mining engineering develops to deep, especially high-ground stress, High-geotemperature, high karst hydraulic pressure and strong exploitation disturbing influence, proposed new requirement to bolt support technology.Therefore, greatly develop the anchor pole technology being applicable under complex geological condition and become the important topic in current mining engineering.
Reaming type bolt support technology has been successfully applied in side slope and base pit engineering, and has obtained good supporting effect.Its reaming is after Completion of Drilling Hole, according to designing requirement position, quantitatively reaming, form a bolthole that has local enlarged body.After slip casting, enlarged body has increased the contact area of anchoring body and the soil body, and anchor pole end is made the combination of using with rubbing action and made anchor-holding force of anchor bolt obtain larger raising.
The bolt support of using in China's mining engineering and side slope and base pit engineering are different, the main distinction is that the country rock in mining engineering is harder, conventionally use the small-bore bolthole of hammer drill Drilling Ф 28～50mm, with cement mortar slip casting or resin explosive roll, make binding material, by the combination between anchor pole, binding material and hole wall, produce anchored force, reach the object of supporting country rock.If the reaming type bolt support technology of using in side slope and base pit engineering can be applied in mining engineering, on the basis of armature boring pore-forming, with reaming bit, make armature boring in end or the position of setting formation enlarged body, anchoring body, enlarged body and hole wall acting in conjunction, will improve anchor-holding force of anchor bolt significantly.The increase of anchored force can reduce anchor pole and boring length, can save drilling time and material consumption again, will bring significant economic benefit.
At present, about the expanding method in geotechnical engineering, mainly comprise mechanical hole reaming both at home and abroad, blast reaming, hydraulic reaming and mud jacking reaming, for the reaming type bolt support technology in mining engineering, the one, adopt blast reaming, hydraulic reaming and mud jacking expanding method cannot meet bolt support to reaming chi, requirement with shape, the 2nd, existing mechanical hole reaming drilling tool is subject to the limitation of construction of the harder and small-bore of country rock, cannot reach larger reaming dimensional requirement, therefore developing small-bore hard rock borehole-enlarging drilling tool has become the key issue of reaming type bolt support technology development in mining engineering.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, easy to operate, can meet the Counterboring apparatus that in mining engineering, reaming type bolt support technology requires.
The technical scheme that technical solution problem of the present invention adopts is: small-bore hard rock Counterboring apparatus comprises apparatus main body, cutting tool, pressure push-rod, position-limitting pin, cutter pin rod.Its feature: (1) is simple in structure: be convenient to processing and install, abrasion of cutting tool is convenient to change; (2) easy to operate: after Completion of Drilling Hole, the drilling rod of rotary drill is connected with apparatus main body, thrust by rig promotes pressure push-rod, pressure push-rod promotes cutting tool and opens in boring, cutter opens with hole wall and contacts, and in the gyration of drilling rod, hole wall is cut, along with pressure push-rod is under the promotion of cutting tool, the opening angle of cutting tool constantly increases, and finally in boring, forms enlarged body.After reaming finishes, cutter is return.(3) reaming size is convenient to adjust: by increasing the wall thickness of apparatus main body, improve device intensity; By changing the length of cutting tool, adjust reaming size; (4) cutting tool adopts cutting mode, is conducive to improve reaming speed, saves time.Adopt alloy to be conducive to the reaming of hard rock.
Small-bore provided by the present invention hard rock Counterboring apparatus, simple in structure, easy to operate, reaming efficiency is high, can meet reaming type anchor pole in mining engineering and prop up expansion technical requirements, the development of novel anchor rod technology in mining engineering and application are all had to important value.

The specific embodiment
The invention provides a kind of small-bore hard rock Counterboring apparatus, below by the specific embodiment, the invention will be further described.Structural parameters (the Ф 50mm of take boring expand to Ф 100mm be example):
Apparatus main body: the installation main body of cutting tool and push rod, its pipe external diameter is Ф 40mm, and bore is Ф 24mm, and length is 400mm;
Cutting tool: be arranged on apparatus main body, rotate with drilling rod, rock is cut, the complete length of run of its both wings is 100mm:
Pressure push-rod: by pressure-acting, promote cutting tool and open, maximum advance distance is 70mm;
Position-limitting pin: the advance distance of limiting pressure push rod;
Cutter pin rod: the rotating shaft of cutting tool motion realizes the handling of cutting tool simultaneously by it.
Implementation method:
(1) device is installed: cutting tool is installed in apparatus main body, is undertaken spacingly by cutter pin rod, then pressure push-rod is connected with apparatus main body, carry out spacing simultaneously with position-limitting pin;
(2) drilling rod is installed: drilling rod is connected with apparatus main body, drilling rod is arranged on jumbolter simultaneously;
(3) reaming: during jumbolter reaming, apply active force by drilling rod to Counterboring apparatus with rotation mechanism and propulsive mechanism.In propulsive mechanism thrust, promote pressure push-rod motion, pressure push-rod promotes cutting tool and opens in boring, cutter opens with hole wall and contacts, cutting tool is invaded rock under axial compression effect, under rotary torque effect, cut fractured rock again, along with the continuous promotion of pressure push-rod to cutting tool, the opening angle of cutting tool also constantly increases, and finally in boring, forms enlarged body.
(4) reaming is cut clearly: after reaming finishes, and with calming the anger or water flowing purge reaming body and eliminating rock quarrel, finally complete reaming.
