The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
As shown in Figure 1, the utility model embodiment provides a kind of laser azimuth appearance, and this laser azimuth appearance is made up of bevel protractor 1, scale 2, slide, laser 4 and level gauge 6; Bevel protractor is a fan-shaped frame; This fan-shaped frame by frame 11 radially, arc frame 13 and radially frame 12 enclose to put and form (being formed in one in the present embodiment); Radially frame 11 and radially the angle between the frame 12 can 0 the degree-180 the degree between, be specially 30 the degree, 60 the degree, 90 the degree, 120 the degree, 150 the degree etc., the angle that can adjust is as required selected; The arc frame 9 that constitutes fan-shaped frame is provided with scale; Scale 2 is a stripe board, and scale 2 one ends are rotatably connected with fan-shaped frame circle centre position, and the corresponding scale of scale other end place is provided with peep hole 3; Slide has a base plate 5, and base plate 5 is provided with installing hole 51, and laser 4 is arranged in the installing hole, and level gauge 6 is fixed on this base plate 5; This base plate 5 is slidingly connected with scale 2; Fan-shaped frame, stripe board and base plate are parallel to each other; And the corresponding installing hole of its length direction 51 positions, stripe board upper edge are provided with peephole 8 (when base plate 5 slided, the transmitting terminal that is contained in the laser 4 on the installing hole 51 can pass through peephole 8 long-range linear aiming reference line positions) on scale 2.Being slidingly connected between base plate 5 and the scale 2 specifically can be fit structure (as shown in Figure 3) or other structures that can slide relatively arbitrarily between fit structure (as shown in Figure 2), sliding sleeve 03 and the slide bar 04 between recess 01 and the protuberance 02.
The laser azimuth appearance that the utility model provides, during use, at first drill site is selected center line benchmark as a reference in the down-hole; With fan-shaped frame horizontal positioned (fan-shaped frame is placed on the horizontal plane) through level gauge 6, as shown in Figure 5, if the range of bevel protractor is the 0-c degree; The radially frame of corresponding c degree is close to rig fuselage 10; Stirring scale 2, that its relative angle chi 1 is rotated to is vertical with center line, and the word shape line that moving sliding base sends laser 4 just in time projects on the center line, can read angle (if b degree) through peep hole 3; The angle a that just can just calculate between rig fuselage and the center line according to the angular range of bevel protractor and the angle of reading then satisfies 90-a+b=c; Can calculate a=90+b-c,, utilize laser to have the function of long-range linear aiming to confirm the direction of rig drill bit (center line of rig drill bit is parallel with the rig fuselage); And receive the external interference factor less, prior art has the high and advantage simple to operate of accuracy relatively.
Embodiment two
Shown in Fig. 6-8; Improvement further as embodiment one; In order to reduce calculating, make the angular readings that observes through peep hole 3 be the angle between rig fuselage 10 and the center line, make reading have more intuitive; The central angle of fan-shaped frame is 90 degree, and promptly radially frame 11 and the angle between the frame 12 radially are 90 to spend.During use, the radially frame 11 and the rig fuselage 10 of 90 degree scales are fitted, promptly c=90 draws a=b by a=90+b-c, and the angle b that from peep hole 3, reads like this is the angle a between rig fuselage and the center line, uses conveniently, has saved calculating.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
