Description
Technical field
The present invention relates to a kind of oblique-proof device tool that is used for the inverted vertical hole construction.Be applicable to the inverted vertical hole construction, the formed vertical usefull space of inverted vertical hole is used to install the inverted plumb line protection tube, and buries inverted plumb line underground in the pillar the most finally, to form the vertical line observing system, is used to monitor the horizontal movement of hydraulic structures such as dam, side slope.
Background technology
The fundamental difference of inverted vertical hole and general boring is the interior hole (hole scattering does not generally surpass 1 ‰) that can find a vertical of actual boring, is lowered to the vertical line protection tube with satisfied, bury vertical line underground after, the distance of pillar inwall any point and vertical line is greater than the requirement of 50mm.Domestic general job practices is with larger aperture perforate (as φ 275mm) at present; Bury guide pipe and creep into long drilling tool (more than the 10m); According to construction precision reducing step by step.The subject matter that exists is complex process, and labour intensity is big, and the engineering time is long, and cost is big; Equipment is huge, is not easy in narrow and small place constructions such as dam gallerys.Under equal conditions, limited the degree of depth of inverted vertical hole.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of oblique-proof device tool that is used for the inverted vertical hole construction is provided, be intended to simple pore-creating technology and rational construction technology, realize the construction of high-precision vertical hole, make the hole scattering rate be controlled at 1 ‰, realize the miniaturization of inverted vertical hole construction equipment, to adapt to the construction of narrow and small place; Reduce labor intensity simultaneously, reduce construction cost, improve the construction comprehensive benefit.
The technical solution adopted in the present invention is: a kind of oblique-proof device tool that is used for the inverted vertical hole construction, have rotating shaft, and it is characterized in that it also comprises two guide rings that are fixed together by bearing support, guide ring is connected by rolling bearing and rotating shaft are rotating.
Even one group of hard alloy blocks of cloth on the circumference of described guide ring.
The external diameter of described guide ring is identical with the particle size drilling tool.
Between the described rotating shaft guide ring oil sealing is housed.
The upper end of described rotating shaft is an interface in the rotating shaft, and this interface has the shrinkage pool of truncated cone-shaped and attacked internal thread.
The lower end of described rotating shaft is the rotating shaft lower interface, and this interface is truncated cone-shaped and has external screw thread.
The invention has the beneficial effects as follows: realized full hole guiding, one footpath on earth, avoided contacting of drill string and hole wall, thereby vibration when having reduced greatly to creep into and additional building force, make drilling process steady, improved the pore-creating precision, creep into resistance owing to having reduced simultaneously, input power reduces, and has realized the miniaturization of inverted vertical hole construction equipment, the drilling rod lightness, technology is oversimplified, and has reduced the difficulty at small space construction inverted vertical hole, has alleviated labour intensity, reduce construction cost, improved the construction comprehensive benefit.
When field testing, construction equipment adopts 300 types or 150 type rigs, has finished the construction of the inverted vertical hole of rice surplus in the of 1800, rice surplus the darkest single hole 70 is checked and accepted once successful qualification rate 100% through monitoring, the pore-creating deviation proportion is controlled best less than 0.5 ‰ all about 1 ‰.
Description of drawings
Fig. 1 is the front view of this utility model.
The specific embodiment
As shown in Figure 1, present embodiment is used for the oblique-proof device tool of inverted vertical hole construction, have and be cylindrical rotating shaft 1 substantially, the top and bottom of rotating shaft are used for jointed rod, interface 1-1 has the truncated cone-shaped shrinkage pool and has attacked internal thread in the rotating shaft of upper end, and the rotating shaft lower interface 1-2 of lower end is truncated cone-shaped and has attacked external screw thread.These routine characteristics are to fixedly connected two guide rings 7 up and down the thickest section of rotating shaft diameter with screw 3 by bearing support 6, be uniform-distribution with several hard alloy blocks 4 on the circumference of guide ring 7, between bearing support 6 and the rotating shaft 1 rolling bearing 5 is housed, is provided with oil sealing 2 between guide ring 7 and the rotating shaft.The external diameter of guide ring 7 is identical with the particle size drilling tool.
This oblique-proof device tool is contained in the middle of two drill strings, and when rotating shaft during with the drill string transfer torque, guide ring 7 only rises sets upright guide effect, and does not turn round or little revolution, thereby simplifies the processing step of boring, has created advantage on earth for realizing a footpath.
