Abstract
The utility model discloses a scale indication guide bar which comprises a guide rod and a dial which is fixedly connected with one end of the guide rod and has scales, wherein the central line of the guide rod is kept perpendicular to the central line of the dial; an indication rod is connected with the circle center of the half-circle of the dial; and a gravity ball is connected with the tail end of the indication rod. The scale indication guide bar is applicable to drilling in angle under the shaft, and by utilizing the gravity droop principle, the drilling angle visualization is realized; by utilizing the scale indication guide bar, the angle for drilling can be read directly by a drilling worker, and the drilling worker can adjust in time according to desired angles, so that the quality of a shot hole is ensured; the convenience for the drilling worker to control the drilling angle is provided, so that the smooth blasting effect is improved; and the working intensity is reduced, the labor is saved, the operation is simple and the use is convenient.
Description
Technical field:
The utility model relates to a kind of measurement facility, the graduation indication guide bars of control perforating angle when relating in particular to bord-up and go-downhill roadway perforating construction under a kind of coal mine.
Background technology:
The band angle perforating work that is absolutely necessary under the coal mine, according to the condition of underground construction, when bord-up and go-downhill roadway construction, need the angle of control perforating, all be that the inspector takes the tilt gauge scene to measure generally speaking, then insert wooden guide bars guiding.There are like this some problems, the one, the inspector might not prepare to measure the borehole angle at work plane all the time, the inspector is had relatively high expectations, the 2nd,, give and guarantee that the quality of perforating brought difficulty with sensation be difficult to judge in the eyes with the mismatch of the borehole angle of beating again other behind the wooden guide bars.
Summary of the invention:
When solving under the coal mine perforating of band angle, angle control hard problem, the purpose of this utility model provide a kind of simple in structure, easy to use, at any time measure the perforating angle, effectively prevent the graduation indication guide bars of perforating angle deviating design angle.
The technical solution of the utility model realizes in the following manner:
A kind of graduation indication guide bars, comprise that guide peg, guide peg one end be fixedly connected with the dial with graduation indication, it is vertical that guide peg center line and dial center line keep, and connects an indicating arm, the terminal connection of indicating arm one gravitation ball at the home position of the semicircle of dial.
Guide peg is that diameter is less than the steel pipe of borehole.
Good effect of the present utility model is:
1, the utility model is applicable to down-hole band angle perforating, utilizes the gravity sag principle, realizes that the jewel hole angle is visual.
2, utilize the utility model can directly be read by the holerr angle of institute's perforating, then the holerr in time adjusts according to required angle, guarantees the quality of borehole; Make things convenient for the holerr to control the perforating angle, thereby improve Smooth Blasting Effects.
3, reduced labour intensity, saved artificial.
4, simple to operate, easy to use.
Description of drawings:
Fig. 1Be theory structure schematic diagram of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: the utility model comprises the dial 2 with graduation indication 5 that guide peg 1, guide peg one end are fixedly connected with, the guide peg center line keeps vertical with the dial center line, home position at the semicircle of dial 2 connects an indicating arm 3, the indicating arm 3 terminal gravitation balls 4 that connect; Guide peg 1 is just measured conveniently less than the steel pipe of borehole for diameter.
Claims (2)
1. graduation indication guide bars, the dial (2) that comprises the band graduation indication (5) that guide peg (1), guide peg one end are fixedly connected with, it is characterized in that: the guide peg center line keeps vertical with the dial center line, home position at the semicircle of dial (2) connects an indicating arm (3), the terminal gravitation ball (4) that connects of indicating arm (3).
2. graduation indication guide bars according to claim 1 is characterized in that: guide peg (1) is the steel pipe of diameter less than borehole.
