Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
In preferred embodiment of the present utility model, as it is shown in figure 1, a kind of drilling pouring pile hole perpendicularity accurately measures
Device, this device includes the bottom support spider 1 in boring periphery and the disk 2 being arranged on spider 1 top, disk 2
Diameter is more than the diameter of boring, so that the orthographic projection of disk is completely covered boring, rail is installed at its diameter in the bottom of disk 2
Road 3, track 3 is slidably fitted with Laser emission and receptor 4, Laser emission and receptor 4 and along track 3 uniform motion and hangs down
Straight transmitting laser signal downwards reception run into the laser signal that boring border is reflected vertically upward, Laser emission and receptor
Connected by wire and a computer 5.
As shown in Figure 1-Figure 3, the measuring method of this device, comprise the following steps:
S1, said apparatus is supported on boring periphery by spider, makes the orthographic projection of disk that boring is completely covered, will swash
Light emission and receptor are placed on the end of track；
S2, Laser emission and receptor from the initial end terminad uniform motion of track, computer recording Laser emission and
Receptor is from being transmitted into the time t received used by laser signal, and walked length L=of each laser signal during calculating this
Vt, v are laser speed, are connected by the straight line of the laser signal of L=2H during this, and H is drillhole height；
S3, when Laser emission and receptor move to the end of track, disk rotational angle [alpha], α=180 °/n, n be from
So number, this end is the initial end next time moved, Laser emission and receptor and at the uniform velocity transports from the initial end terminad of track
Dynamic, computer recording Laser emission and receptor are from being transmitted into the time received used by laser signal, and during calculating this
Walked length L of each laser signal, connects the laser signal straight line of L=2H during this；
S4, repeat step S3, until disk rotational n time, i.e. after disk rotational 180 °, obtain n bar line segment, computer is obtained
The outline of the n bar line segment arrived is connected, and i.e. can get the outline of foot of hole and the outline phase of boring plan vertical projection
Hand over the outer contour of part；
S5, the outer contour of the outer contour obtained in step S4 with boring plan vertical projection is compared, available
Ultimate range s between the two outline, then the angle of inclination holedCalculated by following formula:
In step S3, disk rotational angle [alpha]=5 °, then n=36.Angle [alpha] is the least, and certainty of measurement is the highest.
Simple in construction of the present utility model, as it is shown in figure 1, main by spider, disk, track, Laser emission and acceptance
Device and computer composition.Circle disk center crossed by track, and is fixed on the central authorities of disk.Laser emission and receptor can be along track slidings
OK, and can launch laser signal vertically downward, when laser signal runs into boring border, laser signal is reflected vertically upward, and
Received by Laser emission and receptor.Disk is arranged on above spider, and disk diameter is slightly larger than bore diameter.Spider stands on
Outside boring, make disk projection on the ground can cover boring.Computer controls Laser emission and receptor according to a constant speed
Degree slides the most in orbit, and recording laser is launched and receptor is from being transmitted into the time received used by laser signal automatically,
And calculate this process walked length L of each laser signal, the laser signal straight line of L=2H in each circulation is connected.Just
During beginning state, Laser emission and receptor are placed on one end of track, Laser emission and receptor when sliding into end from initial end
Time, disk rotational 5 °, now Laser emission and receptor slide into initial end from end again, and this process is a circulation, until
Till system runs 36 circulations, disk rotational 180 °.
As it is shown on figure 3, the tilted cylindrical envelope that in figure, solid line represents the be rig actual boring dug out, the vertical circular that dotted line represents
Post is then standard borehole, and H represents drilling depth (known), and s represents between both actual borehole and standard borehole outline
Big distance,Represent misalignment angle.In each cyclic process, the laser signal that Laser emission and receptor are launched vertically downward
Project on boring border, then be reflected back Laser emission and receptor, Laser emission and receptor by laser during this from sending out
Be mapped to reception time-consumingly sends computer to, and computer automatic analysis calculates length L of the experienced route of laser, and stores L
The laser signal of=2H, i.e. projects the laser signal of boring lowermost end, in each circulation, and the laser letter that will store in computer
Number it is linked to be straight line, i.e. obtains actual borehole bottom and cross two diameters intersecting 5 ° in the center of circle, as shown in Figure 2.
The route that in Fig. 2, AD and BC is experienced at boring lowermost end by a circulation inner laser, two lines section intersects 5 °.When
When system has run 36 circulations, i.e. disk rotational 180 °, laser projection solid line in foot of hole can be formed such as Fig. 2 encloses
Figure MABNDC, this outer contour being foot of hole circle and boring top circle intersection (namely tilts to bore
Bottom, hole and the contour line of vertical drilling bottom extremity part), MA ' B ' NDC is then the outline of inclined drill top circle
Line (the namely outer contour of vertical drilling bottom), is easily found 2 PF that offset deviation is maximum from two contour lines
(connected line crosses center of circle O), this distance is the s in Fig. 3, the most now angle of inclination of inclined drillIt is:
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of this utility model claims.
