Abstract
The utility model provides a can improve the rig and creep into efficiency and creep into drilling rod direction deviation prevention damping device of quality, it comprises mandrel (6), overcoat (5), thrust ball bearing (4) (7), plug screw (2) (9), resistant oily sealing washer (3) (8) and lock coupling (1) and lock joint (10).
Description
The utility model relates to and a kind ofly is used to drill through concrete core so that estimate the servicing unit that creeps into of pile foundation quality.
Yet there are no the report of the anti-inclined to one side damping device of drilling rod guiding in the prior art, because not anti-inclined to one side damping device, drilling tool produces vibrations in various degree under high speed rotating, even can't widely different commentaries on classics creep into, its concrete core taking rate is generally about 75%, the boring verticality is in 2%, and drilling efficiency is about 1 meter/hour.
The purpose of this utility model is to reduce the vibrations that drilling tool produces under high speed rotating, and a kind of anti-inclined to one side damping device of drilling rod guiding that can improve the rig drilling efficiency and creep into quality is provided.
Fig. 1 is the structural representation of the anti-inclined to one side damping device of the utility model guiding, wherein:
1--represents the interlocking hoop;
2,9--represents the silk plug;
3,8--represents oil-resistant seal ring;
4,7--represents end thrust ball bearing;
5--represents overcoat;
6--represents axle;
10--represents latching connector;
Below in conjunction with accompanying drawing the utility model is described in detail.
The anti-inclined to one side damping device of this guiding is made up of axle (6), overcoat (5), end thrust ball bearing (4) (7), silk plug (2) (9), oil-resistant seal ring (3) (8) and interlocking hoop (1) and latching connector (10), said axle is connected with oil-resistant seal ring by end thrust ball bearing with overcoat, make axle overcoat when rotating keep motionless, the two ends of said overcoat are close by silk plug envelope, one end of said axle connects the interlocking hoop, and the other end connects latching connector.In addition, the external diameter of overcoat (5) is slightly less than the external diameter of drill bit, and for example the overcoat diameter is got 75.5mm, the then desirable 76mm of outside diameter.When the rig dynamic start, drilling rod is promptly made high speed rotating in boring, because drilling rod and axle (6) in the boring are cascaded with screw thread, therefore axle and drilling rod are done the widely different commentaries on classics of synchronous high-speed, because the effect of end thrust ball bearing (4) (7) and two-man act skeleton oil-resistant seal ring (3) (8), overcoat (5) can not rotated and can cushion the lateral impact forces that swing produced of drilling rod in the hole, set upright drilling rod in drill center with to be unlikely to the drilling rod high speed widely different then produce vibrations and friction thereby reach.
The anti-inclined to one side damping device of guiding has guaranteed the verticality of boring, has improved drilling efficiency, has implemented full hole guiding, promptly on every drilling rod, add a cover guiding vibration abatement, make core-drawing hole verticality slope less than 1%, concrete core taking rate brings up to 99%, rate of penetration up to 4-5 rice/hour.
Claims (1)
1, a kind ofly help rig to drill through concrete core so that estimate the anti-inclined to one side damping device of drilling rod guiding of pile foundation construction quality, it is characterized in that, this device is by axle (6), overcoat (5), end thrust ball bearing (4) (7), silk plug (2) (9), oil-resistant seal ring (3) (8) and interlocking hoop (1) and latching connector (10) are formed, said axle is connected with oil-resistant seal ring by end thrust ball bearing with overcoat, make axle overcoat when rotating keep motionless, the external diameter of said overcoat (5) is slightly less than the external diameter of drill bit, the two ends of overcoat are close by silk plug envelope, one end of said axle connects the interlocking hoop, and the other end connects latching connector.
