Description
Technical field
The utility model relates to a kind of drilling tool, relates in particular to a kind of way-type drilling unit, more specifically, relates to a kind of way-type drilling unit that creeps into fast that is applicable in hard rock.
Background technology
Boring is a very important job in the industries such as mining, building, tunnel in rock, for example bores anchor cable hole, shot hole etc.When boring, all to use drilling tool, according to the principle difference of boring, use different drilling tools.Mainly contain the boring of impact rotating formula boring and swinging at present, so-called impact rotating formula boring is exactly by drill bit rock, soil etc. to be impacted, pushes and make it fragmentation, thereby finishes boring; So-called swinging boring be exactly by drill bit to rock, soil etc. only cut, grinding, thereby finish boring.In when boring, which kind of operating principle no matter, a common characteristic is: all will with drilling rod with the transmission of power of dynamic power machine to drill bit, to finish bore operation.Therefore, the drilling rod that is connected with drill bit is correspondingly also different, such as impact rotating formula drilling rod is arranged, swinging drilling rod etc., and the cross sectional shape of drilling rod divide again a variety of, round drill rod for example, hexagon drilling rod, spirality drilling rod etc.The drilling rod that often adopts has dual mode at present, a kind of is to adopt impact rotating formula drilling rod, cooperating corresponding drill bit to creep into again, is that impact force and the cutting force with dynamic power machine all passes to drill bit, by the drill bit frequent impact rock, soil etc. is smashed to reach the purpose of creeping into; Another kind is to adopt the swinging drilling rod, cooperates corresponding drill bit to creep into again, and only cutting force and the grinding force with dynamic power machine passes to drill bit, only by drill bit rock, soil etc. is cut or grinding reaches the purpose of creeping into.
All there is fatal shortcoming in above-mentioned dual mode, and for first kind of mode, because of mechanical oscillation when holing are bigger, power requirement is higher, and drilling rod and hole wall existence friction, and therefore, power attenuation is big, noise is high, rate of penetration is slow and be difficult to get out deep hole.For the second way, though can realize boring by the cutting of rotation at a high speed, thereby improved rate of penetration, also can bore darker hole, but the raising of rotating speed, must cause the friction aggravation between drilling rod and hole wall, this not only makes power attenuation strengthen, and the rate of wear of drilling rod is accelerated, and the stability of drilling rod and safety also will reduce greatly.
Above-mentioned prior art common characteristic is: rotation by drilling rod and/or axially-movable with the transmission of power of rig to drill bit, thereby there is common shortcoming: be exactly that drilling rod rubs with hole wall always in motion process, when boring is dark, having greatly, power will consume in the friction of drilling rod and hole wall, for the needs of holing, can only increase power, this has further caused the waste of the energy again; In addition, there are friction in drilling rod and hole wall during owing to boring, and the drilling rod life-span also can shorten because of wearing and tearing, cause the increase of boring cost.In addition, the run of steel of above-mentioned prior art is fixed, if bore the hole of different depth, can only realize by changing drilling rod, thus a plurality of drilling rods, processing cost height and the construction inconvenience that need to make different size.
Therefore, develop a kind of friction that can reduce drilling rod and hole wall, exceeding the drilling tool that under the situation of consumed power enough rotating speeds is offered drill bit, seem particularly important and urgent, will reduce the specification of drilling rod simultaneously, to adapt to the needs that bore the different depth hole.
The utility model content
Cause problem such as the high and inconvenience of constructing of cost or one of at least in order to solve that the drilling rod that above-mentioned prior art exists is big with the hole wall friction, efficient is low, the drilling rod specification more, the utility model provides a kind of way-type drilling unit, has solved the above-mentioned defective of prior art effectively.
