Abstract
The invention discloses a non-coring cylindrical rock drill of a rotary drilling rig, which comprises a cylindrical drill body and a flange, wherein the flange is arranged at the upper end of the cylindrical drill body; a central tube is arranged in the center of the cylindrical drill body; the upper end of the central tube is connected with the upper end of the cylindrical drill body, and is coaxial with the flange; the central tube is longer than the cylindrical drill body; the lower end of the central tube is 5 to 10 cm extended out of the bottom end of the cylindrical drill body; bullet cutting picks II are uniformly distributed at the bottom end of the central tube; bullet cutting picks I are uniformly distributed at the bottom end of the cylindrical drill body; and slant edges are arranged on the outer wall of the cylindrical drill body. The non-coring cylindrical rock drill ensures borehole verticality, small drilling resistance and large soil deposition space.
Description
Technical field
The present invention relates to a kind of rock tube and bore, especially relate to a kind of rotary drilling rig and do not get core rock tube brill.
Background technology
In civil works, adopt rotary drilling rig to hole usually, the moment of torsion and the plus-pressure of rotary drilling rig output finally all pass to drill bit, and the height of drill quality has determined whether work progress can efficiently carry out.When rotary drilling rig is worked, select for use suitable drilling tool to help energy conservation, accelerate speed of fulfiling hole and improve hole quality.At present, rotary drilling rig rock tube bores to be divided into and gets core rock tube brill and do not get two kinds on core rock tube brill.Get core rock tube brill lower end and be welded with outside the sub warhead pick, the leaf of hinge of support core is housed on the cylinder inboard wall.The existing leaf of hinge that does not have the support core on the core rock tube brill inwall of not getting.The main effect that rotary drilling rig rock tube bores is to be to empty becoming flexible around the core in the hole, creates the broken scope of freedom for being lowered to the broken core of the short augers of embedding rock later on.
The existing core rock tube of not getting bores, and often occurs following problem in use:
(1) be plane structure because of not getting core rock tube brill bottom, crowns all when creeping into contact with the stratum simultaneously, cause all crowns simultaneously stressed, produce slippage easily when creeping into, and are difficult to the verticality of assurance boring, and the aperture is strengthened, and cause damage;
(2) drill body is thick and heavy, clumsy, by drill body outer wall transfer torque, easily makes tube bore a wall and thickens and make and deposit native space and reduce;
(3) be arranged in the vertical bar of drill body outer wall, cause that to creep into resistance big, the energy consumption height;
(4) for the bigger basement rock stratum of hardness, big erratic boulder layer and hard permafrost, need to adopt the rock tube to bore and cooperate short augers and Double bottom plate to drag for the sand borer head and could normally carry out boring work, directly with short augers or revolve dig drill bit all compare difficult, complex procedures, efficient is low.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the invention provides a kind of boring verticality height, it is little to creep into resistance, and it is big to deposit native space, and operation is simple, and the rotary drilling rig that efficient is high is not got core rock tube and is bored.
Technical scheme of the present invention is: it comprises cylinder drill body and flange, flange is located at cylinder drill body upper end, cylinder drill body center is provided with central tube, described central tube upper end is connected with cylinder drill body upper end, and coaxial with flange, and described central tube length is greater than cylinder drill body length, 5～10cm outside the cylinder drill body bottom is stretched out in the central tube lower end, the central tube bottom is evenly distributed with sub warhead pick II, and described cylinder drill body bottom average mark is furnished with sub warhead pick I, and described cylinder drill body outer wall is provided with slanting.
Preferred 18 or 24 of the sub warhead pick I quantity of described cylinder drill body bottom, adjacent sub warhead pick I is staggered, and is mutually 30 ° ~ 45 °.
Preferred 6 of the sub warhead pick II quantity of described central tube bottom is mutually 50 ° ~ 70 °.
Preferred two groups of the slanting of described cylinder drill body outer wall, two groups of slantings are symmetrically distributed on the cylinder drill body outer wall, preferred 12 of every group of slanting quantity, 4 rows, 3 row evenly distribute, and every row's slanting height reduces successively.
Described slanting shape is preferably cuboid or square, and section is a square, and long: wide: height is 7～1: 1: 1, each slanting and cylinder drill body axis were 60 ° ~ 75 °.
Use the present invention, dig when creeping into revolving, be located at the sub warhead pick II of central tube bottom and creep into the form of a contact earlier, have good location and guide effect, help guaranteeing the verticality of holing; When the sub warhead pick I of cylinder drill body lower end began to contact the stratum, cylinder drill body outer wall and central tube were simultaneously stressed, help alleviating the moment of torsion on the cylinder drill body wall, reduce the thickness of cylinder drill body wall, and drill body is lightly changed; Along with the rotation of cylinder drill body is goed deep into, the slanting on the cylinder drill body wall makes the cylinder drill body creep into along the direction spiral of slanting, and because the slanting aspect ratio is less, thereby help reducing resistance, cut down the consumption of energy.Central tube has the effect that shifts to an earlier date broken soil layer, need not to be used short augers and the Double bottom plate drags for the sand borer head, and operation is simple, the efficient height.

Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is a partial structurtes sectional view embodiment illustrated in fig. 1;
Fig. 3 is a vertical view embodiment illustrated in fig. 1.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises cylinder drill body 2, flange 4 and slanting 7, described flange is located at cylinder drill body upper end, cylinder drill body 2 centers are provided with central tube 3, described central tube 3 upper ends are connected with cylinder drill body 2 upper ends, and it is coaxial with flange 4, described central tube 3 length are greater than cylinder drill body 2 length, 8cm outside cylinder drill body 2 bottoms is stretched out in central tube 3 lower ends, and central tube 3 bottoms are evenly distributed with 6 sub warhead pick II 5, are mutually 60 °, described cylinder drill body 2 bottoms are 18 sub warhead pick I 1 of distribution evenly, adjacent sub warhead pick I 1 is staggered, and is mutually 40 °, and described cylinder drill body 2 outer walls are provided with two groups of slantings 7, two groups of slantings 7 are symmetrically distributed on the cylinder drill body outer wall, 12 of every group of slantings, 4 rows, 3 column averages distribute, and every row's slanting height reduces successively, described slanting 7 is shaped as cuboid, section is a square, and long: wide: height is 5: 1: 1, and each slanting and cylinder drill body 2 axis are 70 °.
