A kind of boring direction positioner and using method thereof
Technical field
The invention belongs to Tunnel Engineering and mechanical field, relate to a kind of boring direction positioner and using method thereof.
Background technology
At present, in tunnel monitoring or blast working drilling process, need for the accuracy and actual probing ensureing results of drilling
Want, need the orientation angles of each boring is accurately determined.Simultaneously in drilling instrument boring procedure, some light and handy rigs with
The vibration of drill bit, it is easy to deviation original direction so that boring is not straight, cause boring failure or drilling rod bit freezing even drilling rod to break
The engineering loss such as split.
Traditional way be utilize the azimuth circle of surveyor's transit to determine (or the method utilizing tape measure to calculate comes thick
Slightly demarcate), demarcate azimuth technical staff every time and field worker coordinates, it is generally required to more than 3 people complete, slightly slip up institute
The angular deviation measured is very big, needs the longer time to proofread, and whole operating process complex steps is the longest, manpower thing
Power puts into big, and cannot realize driller and adjust bore direction angle at any time, thus causes drilling inefficiency,
The orientation of boring and the error at inclination angle, directly influence accuracy and the precision of results of drilling.
The most simple and quick effectively determine boring direction, reduce in boring procedure simultaneously and produce because Field Force holes improper
Raw boring direction error, the problems such as distortion of holing, for drilling technique instantly, there is the biggest realistic meaning.
A kind of laser orientation instru-ment of Chinese patent application Publication No. CN103089244A at present, this location instrument is by angle
Chi, pointer, slide and laser device composition, this device needs to use by rig, has some limitations on using, and instrument
Device is directly placed on drilling machine body, requires rig, during drill bit regulation, is susceptible to pre-determined orientation again
There is deviation.
Summary of the invention
The present invention needs the problem solved to be for above-mentioned the deficiencies in the prior art, and provides a kind of boring direction location dress
Put and using method.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of boring direction positioner, including base, pedestal and location bar, the upper surface of base is provided with circular scale,
The circumferential surface of circular scale is provided with scale, and pedestal is movably connected on the upper surface of circular scale by longitudinal rotating shaft,
Pedestal carries out 360 degree of rotations with longitudinal rotating shaft for rotating shaft, and pedestal is hemispherical, and the edge grain along its place, axis is provided with half
Circular groove, location bar is movably connected in half slot by horizontal rotating shaft, and location bar carries out 180 degree with horizontal rotating shaft for rotating shaft and turns
Dynamic, at the outer circumference surface of half slot, it is provided with scale, base is provided with the locating part group I limiting base motion, and pedestal is provided with
Limiting the limit assembly II of location bar motion, the lower surface of base is provided with the fixture for fixed placement.
Locating part group I includes positioning I and bolt, and hole I, location is longitudinally through being located on pedestal, circular scale and base.
Limit assembly II includes positioning II and bolt, and location II is respectively arranged on the inwall of half slot both sides.
Fixture is T-slot.
Location bar (1) is in elongated cylinder shape.
The using method of boring direction positioner, it is characterised in that: comprise the following steps:
The first step, the boring side of demolition site select suitable rock surface;
Second step, in rock surface, squeeze into expansion bolt, flat of expansion bolt and nut are snapped in the fixture of base
In so that this device is fixed on rock surface;
3rd step, requirement according to boring direction, rotating base and location bar reach specified angle direction, and by locating part group
I and locating part group II fix;
4th step, the drilling rod of drilling instrument is parallel to position bar, carry out bore operation;
5th step, hole, taken out this device, keep well standby.
Compared with prior art, the invention has the beneficial effects as follows:
(1) this device operating procedure is simple, and sense of direction is pointed to directly perceived.
(2) this device is once fixed, and the error of orientation angles can be revised at any time and change, and can eliminate brill to a certain extent
The operating error of location, direction, hole and systematic error, improve the accuracy of results of drilling.
(3) this device realizes driller and adjusts bore direction angle at any time, has practicality, is greatly improved brill
Hole efficiency.
(4) this device volume is little, easy to carry, the orientation angles of keyhole that can be the easiest.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only with
The basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
As Figure 1-3, a kind of boring direction positioner, including base, pedestal and location bar, on the upper surface of base
Being provided with circular scale, the circumferential surface of circular scale is provided with scale, and pedestal is movably connected in circular quarter by longitudinal rotating shaft
On the upper surface of scale, pedestal carries out 360 degree of rotations with longitudinal rotating shaft for rotating shaft, and pedestal is hemispherical, along its place, axis
Edge grain be provided with half slot, location bar is movably connected in half slot by horizontal rotating shaft, positions bar and with horizontal rotating shaft is
Rotating shaft carries out 180 degree of rotations, is provided with scale at the outer circumference surface of half slot, and base is provided with the locating part limiting base motion
Group I, pedestal is provided with the limit assembly II limiting location bar motion, and the lower surface of base is provided with fixing for fixed placement
Part.
Locating part group I includes positioning I and bolt, and hole I, location is longitudinally through being located on pedestal, circular scale and base.
Limit assembly II includes positioning II and bolt, and location II is respectively arranged on the inwall of half slot both sides;Convenient location
After bar tangentially regulates angle, the half slot on bar both sides, location inserts bolt and fixes.
Fixture is T-slot, and T-slot coordinates with expansion bolt and is fixed on cliff.
Location bar (1) is in elongated cylinder shape.
The using method of boring direction positioner, it is characterised in that: comprise the following steps:
