Description
Technical field
This utility model relates to bit technique field, more specifically a kind of guiding Anti-inclining drill bit.
Background technology
In the engineerings such as exploration, building pile foundation or oil-gas mining, using bit bore is a requisite ring, but, during or rig generation slight inclination harder on stratum, easily there is inclined hole in boring, and in prior art, have has added a location drill bit in drill bit front portion, principle and first with little drill bit punch, big drill bit reaming is the same, it is possible to prevent to a certain extent because vibrations cause borehole throw, but the drill bit run-off the straight causing the reasons such as rig slight inclination prevents effect the most well.The drill bit drilled straight down can be remained hence it is highly desirable to a.
Summary of the invention
For solving the problems referred to above, overcoming the deficiencies in the prior art, this utility model to provide a kind of simple in construction, fringe cost is low, practical guiding Anti-inclining drill bit.
For achieving the above object, the guiding Anti-inclining drill bit that this utility model provides, including drill body and slope-preventing device, it is characterized in that: described slope-preventing device includes anti-oblique wing, chip area, middle trepanning, described drill body bottom is provided centrally with guide head, and middle part is inlaid with wear-resistant block, and upper end center is connected with drillstock one end, being arranged with the slope-preventing device equal with drill body maximum gauge on described drillstock, slope-preventing device top is additionally provided with limited block.
Further, described anti-oblique wing one end is fixedly linked with middle trepanning outer wall, and the other end is arc-shaped, has been the chip area discharging the by-product effect such as liquid, drilling cuttings of boring between two anti-oblique wings.
Further, described drillstock other end jointed rod.
The beneficial effects of the utility model are: this utility model arranges guide head in drill body front end, one device preventing tilting that can recycle is set on drillstock, simple in construction, cost is low, practical Anti-inclining is effective, after drill bit is scrapped, device preventing tilting can disassemble, and is installed on green bit be continuing with.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the structural representation of this utility model slope-preventing device；
In accompanying drawing: 1, drillstock, 2, slope-preventing device, 3, wear-resistant block, 4, guide head, 5, anti-oblique wing, 6, chip area, 7, middle trepanning, 8, drill body, 9, limited block.
Detailed description of the invention:
Clearer for the purpose making this utility model implement, technical scheme and advantage, below in conjunction with accompanying drawing of the present utility model, this utility model is further described in more detail.
To in description of the present utility model; it will be appreciated that; indicating position or position relationship be described as based on orientation shown in the drawings or position relationship; it is for only for ease of description this utility model and simplifies description; rather than instruction or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that restriction to this utility model protection domain.
In accompanying drawing 1 and accompanying drawing 2, the guiding Anti-inclining drill bit that this utility model provides, including drill body 8 and slope-preventing device 2, it is characterized in that: described slope-preventing device 2 includes anti-oblique wing 5, chip area 6, middle trepanning 7, described drill body 8 bottom is provided centrally with guide head 4, middle part is inlaid with wear-resistant block 3, upper end center is connected with drillstock 1 one end, drillstock 1 other end jointed rod, the slope-preventing device 2 equal with drill body 8 maximum gauge it is arranged with on described drillstock 1, drillstock 1 is additionally provided with limited block 9 in slope-preventing device 2 top, prevent the relative drillstock 1 of slope-preventing device 2 from producing vertical displacement；Described anti-oblique wing 5 one end is fixedly linked with middle trepanning 7 outer wall, and the other end is arc-shaped, has been the chip area 6 discharging the by-product effect such as liquid, drilling cuttings of boring between two anti-oblique wings 5.
Slope-preventing device 2 is connected by pin key is fixing with drillstock 1, and device preventing tilting rotates with drill bit, or device preventing tilting is connected by bearing with drillstock 1, and device preventing tilting can rotate relative to drillstock 1；The length on a diameter of two the most anti-oblique wing 5 arc tops of slope-preventing device 2, slope-preventing device 2 diameter is equal with drill body 8 maximum gauge, the anti-oblique wing 5 arc top of slope-preventing device 2 contacts with drill hole inner wall, by slope-preventing device 2 and the active force of drill hole inner wall and counteracting force, prevents drill bit run-off the straight.
This utility model arranges guide head 4 in drill body 8 front end, and drillstock 1 arranges a device preventing tilting that can recycle, simple in construction, cost is low, and practical Anti-inclining is effective, after drill bit is scrapped, device preventing tilting can disassemble, and is installed on green bit be continuing with.
