Abstract
Dig rig PDC drill bit soon including the barrel drill drill bit, evenly welds a plurality of PDC rib teeth and a plurality of PDC board tooth on the barrel drill drill bit, a plurality of compound pieces are inlayed according to a scaling setting to the quantity of PDC rib tooth and PDC board tooth on the rib tooth body of PDC rib tooth, inlay a plurality of compound pieces on the board tooth body of PDC board tooth. The utility model discloses dig the rig drill bit soon and adopt PDC rib tooth and PDC board tooth to substitute present pick, thereby used compound piece to strengthen the hardness of brill tooth, do not need big moment of torsion rig just can realize having improved and having crept into efficiency the creeping into of rock stratum, have that the abrasion resistance is good, hardness is high, the running cost is low and vibrate little advantage.
Description
Technical field
This utility model relates to construction machinery equipment technical field, is specifically related to a kind of rotary drilling rig PDC drill bit.
Background technology
Along with developing rapidly of China's economic, the construction market of China is fiery abnormal especially, and the big speed of its scale is fast, and the Dou Shi world respectively makes the country prosperous and can only hope that it turns round and look at the back of the body.Pile foundation is the basis of building, and construction technology there has also been considerable just entering and development.Rotary drill machine, due to features such as its high efficiency, environmental protection, low consumptions, is widely used in industry and civil buildings especially.There are some high ferros, at a high speed, on the building site of the cast-in-situ bored pile of light rail, occur in that especially and only allow rotary drilling rig to march into the arena the regulation of construction.Whole nation rotary drilling rig quantity is more than 10,000 according to incompletely statistics.Rotary drilling rig machine lathe turner's principle is with internal combustion engine drive hydraulic system principle, in the way of rotary cutting excavation, excavates a deep 10-80 rice from original ground to underground, and the deep hole of diameter 0.5-2.5 rice, then descending reinforcing cage casting concrete is to ground.Each building have several to hundreds of such buried concrete post as basis.
Rotary drilling rig in some soft stratums are constructed because its efficiently, low energy consumption, environmental protection be widely used.But just less desirable in constructing in some medium-hard rock stratum, it may appear that creeping into difficulty, the time is long, and oil consumption and pick consume huge, the huge strong shake of rig, make rig damage serious, even have a strong impact on the life-span of rig.This is because use pick to cause on drill bit, because using pick is the mode of creeping into that pick press-in crushes rock stratum by the big pressure of rotary drilling rig hydraulic system, plus-pressure reaches more than 28 tons, and big model rig has reached 42 tons, but efficiency neither be highly desirable.
PDC bores tooth, PDC is English: PolycrystallineDiamondCompact i.e. composite polycrystal-diamond, because PDC operation principle is similar with Lathe turning tool operation principle, improve rotating speed, strengthen the hardness boring tooth, decreasing the thickness of cutting every time, make work efficiency improve more than 2 times, cost reduces more than 5 times.
Utility model content
This utility model provides a kind of rotary drilling rig PDC drill bit, to solve rotary drilling rig that prior art exists in the serious problem of medium-hard rock stratum construction damage.
This utility model solves its technical problem and be the technical scheme is that
A kind of rotary drilling rig PDC drill bit, including a drill bit, uniform welding some PDC rib tooth and some PDC plate teeth on cylinder drill bit, the quantity of PDC rib tooth and PDC plate tooth is arranged according to a certain percentage, the rib tooth body of PDC rib tooth is inlayed some composite sheet, the plate tooth body of PDC plate tooth inlays some composite sheet.
On above-mentioned cylinder drill bit, the quantitative proportion of PDC rib tooth and PDC plate tooth is 1:6.
Above-mentioned PDC rib tooth composite sheet and PDC plate tooth composite sheet are all made diamond sheet by outrunner to form with hard metal tip compacting below.
Operation principle of the present utility model: the effect of PDC rib tooth is to creep into protection cylinder to derive boring mud reaming；The effect of PDC plate tooth is to creep into protection cylinder reaming; PDC rib tooth and PDC plate tooth are distributed on a drill bit according to a certain percentage; rotating speed can be improved; rotary drilling rig rotating speed is not less than 20 rpms; strengthen the hardness (i.e. synthetic diamond) boring tooth and decrease the thickness of cutting every time; cutting is less than 4 centimetres every time, and the work efficiency made improves more than 2 times, and cost reduces more than 5 times.
This utility model drilling bit of rotary-digging drilling rig adopts PDC rib tooth and PDC plate tooth to substitute existing pick, employ composite sheet thus strengthening the hardness boring tooth, just need not can realize creeping into lithostratigraphy by high-torque drilling, improve drilling efficiency, have that wear resistence is good, hardness is high, operating cost is low and vibrates little advantage.

Detailed description of the invention
Such as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of rotary drilling rig PDC drill bit, including a drill bit 1, uniform welding some PDC rib tooth 2 and some PDC plate teeth 3 on cylinder drill bit 1, the quantity of PDC rib tooth 2 and PDC plate tooth 3 is arranged according to a certain percentage, the rib tooth body 21 of PDC rib tooth 2 inlays some composite sheet 22, the plate tooth body 31 of PDC plate tooth 3 inlays some composite sheet 32, on cylinder drill bit, the quantitative proportion of PDC rib tooth and PDC plate tooth is 1:6, PDC rib tooth composite sheet and PDC plate tooth composite sheet are all made diamond sheet by outrunner to form with hard metal tip compacting below.
Operation principle of the present utility model: the effect of PDC rib tooth is to creep into protection cylinder to derive boring mud reaming；The effect of PDC plate tooth is to creep into protection cylinder reaming; PDC rib tooth and PDC plate tooth are distributed on a drill bit according to a certain percentage; rotating speed can be improved; rotary drilling rig rotating speed is not less than 20 rpms; strengthen the hardness (employing composite sheet and synthetic diamond) boring tooth and decrease the thickness of cutting every time; cutting is less than 4 centimetres every time, and the work efficiency made improves more than 2 times.Cost reduces more than 5 times.
We take pick and PDC to bore tooth and do a contrast table, as follows:
It will be a mileage board in rotary drilling rig development history that PDC bores tooth replacement pick, also can cause very big impact to each producer in research and development manufacture rotary drilling rig.
