Abstract
The utility model provides an inner spiral cylinder type combined rock drilling tool, which comprises a connecting part, an outer cylinder body, a spiral mandrel, a spiral blade, a plurality of cutting tools and the like; the upper part of the outer cylinder body is fixedly connected with the connecting cover plate into a whole, and the helical blade and the helical mandrel are fixedly connected with the connecting flange through the mandrel connecting plate; the plurality of cutting tools are fixedly connected to the lower ends of the outer cylinder body and the helical blade; the outer surface of the outer cylinder body is fixedly connected with a plurality of groups of evenly arranged spirally rising wear-resistant strips. After the cutting tool on the outer cylinder cuts the rock stratum in an annular mode, the rock core enters the cylinder, the cutting tool on the helical blade breaks the rock core, the broken rock core enters a space between the mandrel and the outer cylinder, and in the drill lifting process, the helical blade, the outer cylinder and the mandrel form a space, so that the capacity of carrying the rock core is greatly improved, and the drilling efficiency and the hole forming speed of the drilling tool are improved.
Description
Technical field
The utility model relates to a kind of inner spiral drum-type combination rock drilling tool, is applicable to be drilled to the hole construction operation.
Background technology
The selection of drilling tool is most important in rotary drilling rig drilling construction process.Under the ground consisting of hard rock drilling condition, can select cartridge type rock drilling tool and short spiral drill for use, but in actual application, all exist the problem that influences drilling efficiency and hole quality.The operating principle of common cartridge type rock drilling tool is that the cutting element of drilling tool outer cylinder body below cuts out a cannelure in the stratum, utilize on the rig power of lifting to break rock core when boring carrying, rock core relies on that adhesion between the landwaste and card are stifled to be carried to removal behind the face of land by drilling tool.Its advantage is that the specific pressure that is applied on the cutting element is big; the stock-removing efficiency height; but dig in the drilling and forming hole process owing to auger ability, rock core major diameter reason such as formation characteristics when revolving, regular meeting occurs breaking rock core, or landwaste situation about coming off in putting forward the brill process.The cutting element that short spiral drill utilization is arranged along helical blade can effective broken rock core, but the situation that the rock slag comes off from the blade outside appears in regular meeting.Therefore revolve the worker's method that adopts hierarchical composition to creep into usually at present in the drilling construction process of digging at heavy caliber at present, promptly adopt the cutting of cartridge type rock drilling tool and the removal of core of small-sized earlier, the spiral drill that re-uses big specification is subsequently finished reaming work, re-use scouring bit at last and finish pore-forming work, complex procedures, inefficiency.
In such cases, need the new rock drilling tool of research, effectively solve the problem that ground consisting of hard rock crept into and carried rock core, simplify job step, improve drilling efficiency.
Summary of the invention
Revolve and dig the drilling construction complex procedures and creep into difficulty, be difficult to effectively carry the problem of rock core in order to solve present ground consisting of hard rock, the utility model provides a kind of inner spiral drum-type combination rock drilling tool, and this drilling tool can be finished the work of boring, detritus, pore-forming.
This drilling tool is made up of adpting flange 1, reinforcing rib 2, connection cover plate 3, outer cylinder body 4, wear rib 5, mandrel junction plate 6, spiral mandrel 7, helical blade 8, cutting element 9, pass through openings 10, and described outer cylinder body is fixedlyed connected with adpting flange by connecting cover plate.The spiral mandrel is concentric fully with outer cylinder body, fixedlys connected with adpting flange by the mandrel junction plate.Fixedlying connected with mandrel in the inboard of helical blade, fixedlys connected with the inwall of outer cylinder body in the outside.Several helical blades are along the circumferential direction evenly arranged.Described cutting element is separately fixed at the lower end of outer cylinder body and helical blade.
Preferably, the lower end of the cutting element on the described helical blade is higher than the lower end of cutting element on the outer cylinder body.
Preferably, described helical blade is set to two, symmetric arrangement.
Preferably, described several wear ribs are divided into 2 to 3 groups, and circumferencial direction arranges that evenly every group of wear rib prolongs axial direction from top to bottom and evenly arrange at interval.
Described pass through openings is evenly arranged in the space of respectively organizing between the wear rib in a circumferential direction.
Preferably, the position of each pass through openings is arranged on the differing heights position of cylindrical shell.
Urceolus creeps in advance, utilizes the cutting element on the outer cylinder body poor with respect to the difference in height and the radial position of the cutting element on the helical blade, realizes that classification is crept into, the function of fragmentation.Cutting element cuts the stratum earlier on the outer cylinder body, utilize the specific pressure that cutting element is bigger on the outer cylinder body to overcome confined pressure cutting stratum, stratum earlier, rock core enters cutting element on the inner rear screw blade of outer cylinder body to begin the rock core of removing after the confined pressure is carried out fragmentation cutting, and the rock core after the fragmentation leads along helical blade and enters in the space between cylinder inboard wall and the mandrel.In putting forward the brill process, compared with the cartridge type rock drilling tool of the single cylinder of same outer diameter as specification, inner spiral drum-type combination rock drilling tool has carried out fragmentation to rock core after the cutting rock stratum, and required pulling force significantly reduces.Rock core between mandrel and the cylinder inboard wall relies on frictional force and the jam power between mandrel and the outer cylinder body inwall to be carried to ground, outer cylinder body inner surface and spiral mandrel external surface and helical blade are formed the annular space of relative closure, this design has reduced the inner barrel space, increased the draw ratio of rock core, improved to carry the stifled probability of rock core wedge-shaped card takes place in the brill process, rock core is easy to carry.
The beneficial effects of the utility model are that a kind of drilling tool is realized multiple function, improve the effect of coring, and simplify working procedure, improve drilling efficiency, effectively reduce cost.
