A kind of boring direction positioning device and its application method
Technical field
The invention belongs to Tunnel Engineering and machinery field, it is related to a kind of boring direction positioning device and its application method.
Background technique
Currently, in tunnel monitoring or blast working drilling process, to guarantee that accuracy and the practical probing of results of drilling need
It wants, needs accurately to determine the orientation angles of each drilling.Simultaneously in drilling instrument boring procedure, some light and handy drilling machines with
The vibration of drill bit, it is easy to deviate original direction, so that drilling is not straight, cause drilling failure or drilling rod bit freezing even drilling rod disconnected
The engineerings loss such as split.
Traditional way be determined using the azimuth circle of surveyor's transit (or using tape measure calculate method come slightly
Slightly demarcate), azimuth technical staff and field worker cooperation are demarcated every time, generally requires 3 people or more to complete, and slightly make mistakes institute
The angular deviation measured is very big, takes a long time to proofread, and whole operation process steps are cumbersome, and time-consuming, manpower object
Power investment is big, and cannot achieve driller and adjusted at any time to bore direction angle, so as to cause work low efficiency is drilled,
The orientation of drilling and the error at inclination angle directly influence the accuracy and precision of results of drilling.
How simple and quick effective determining boring direction, while reduce in boring procedure because Field Force drilling it is improper due to produce
The problems such as raw boring direction error, drilling is distorted, for drilling technique instantly, there is very big realistic meaning.
A kind of laser orientation instru-ment of Chinese patent application Publication No. CN103089244A at present, the location instrument is by angle
Ruler, pointer, slide and laser composition, device needs are used by drilling machine, are had some limitations in use, and instrument
Device is directly placed on drilling machine body, is required to drilling machine, in drill bit adjustment process, is easy to happen pre-determined orientation again
It deviates.
Summary of the invention
Problem to be solved of the present invention is in view of the above shortcomings of the prior art, and to provide a kind of boring direction positioning dress
It sets and its application method.
In order to solve the above technical problems, the technical solution adopted by the present invention is that:
The upper surface of a kind of boring direction positioning device, including pedestal, pedestal and locating rod, pedestal is equipped with limbus
Disk, the circumferential surface of circular scale are equipped with scale, and pedestal is movably connected in the upper surface of circular scale by longitudinal shaft
On, pedestal carries out 360 degree rotation by shaft of longitudinal shaft, and pedestal is hemispherical, sets along the edge grain where its central axes
There is half slot, locating rod is movably connected in half slot by horizontal rotating shaft, and locating rod carries out 180 degree by shaft of horizontal rotating shaft
Rotation, scale is equipped with along the outer circumference surface of half slot, and pedestal is equipped with the locating part group I of limitation base motion, sets on pedestal
The limit assembly II of restricted locating rod movement, the lower end surface of pedestal are equipped with the fixing piece for fixed placement.
Locating part group I includes location hole I and bolt, and location hole I is longitudinal through set on pedestal, circular scale and pedestal
On.
Limit assembly II includes location hole II and bolt, and location hole II is respectively arranged on the inner wall of half slot two sides.
Fixing piece is T-slot.
Locating rod (1) is in elongated cylinder shape.
The application method of boring direction positioning device, it is characterised in that: the following steps are included:
The first step selects suitable rock surface beside the drilling of demolition site;
Second step squeezes into expansion bolt into rock surface, and flat of expansion bolt and nut are caught in consolidating for pedestal
Determine in part, so that the present apparatus is fixed on rock surface;
Third step, the requirement according to boring direction, rotating base and locating rod reach specified angle direction, and pass through limit
Part group I and locating part group II fix;
The drilling rod of drilling instrument is parallel to locating rod by the 4th step, carries out bore operation;
5th step, drilling are completed, and are taken out the present apparatus, are kept well spare.
Compared with prior art, the beneficial effects of the present invention are:
(1) present apparatus operating procedure is simple, and sense of direction is directed toward intuitive.
(2) once present apparatus is fixed, the errors of orientation angles can modifications and variations at any time, brill can be eliminated to a certain extent
The operating error and systematic error of hole direction positioning, improve the accuracy of results of drilling.
(3) present apparatus realizes that driller adjusts bore direction angle at any time, has practicability, greatly improves brill
Hole efficiency.
(4) present apparatus is small in size, easy to carry, the orientation angles of control drilling that can be more effectively easier.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1-3, a kind of boring direction positioning device, including pedestal, pedestal and locating rod, on the upper surface of pedestal
Equipped with circular scale, the circumferential surface of circular scale is equipped with scale, and pedestal is movably connected in round quarter by longitudinal shaft
On the upper surface of scale, pedestal carries out 360 degree rotation by shaft of longitudinal shaft, and pedestal is hemispherical, where its central axes
Edge grain be equipped with half slot, locating rod is movably connected in half slot by horizontal rotating shaft, and locating rod is with horizontal rotating shaft
Shaft carries out 180 degree rotation, and scale is equipped with along the outer circumference surface of half slot, and pedestal is equipped with the locating part of limitation base motion
Group I, pedestal are equipped with the limit assembly II of limitation locating rod movement, and the lower end surface of pedestal is equipped with the fixation for fixed placement
Part.
Locating part group I includes location hole I and bolt, and location hole I is longitudinal through set on pedestal, circular scale and pedestal
On.
Limit assembly II includes location hole II and bolt, and location hole II is respectively arranged on the inner wall of half slot two sides;It is convenient
After locating rod tangentially adjusts angle, bolt is inserted on the half slot on locating rod both sides and is fixed.
