Description
Technical field: the utility model relates to a kind of measuring apparatus, and specifically the coal mine gas extraction drilling machine is measured the portable laser angle measuring instrument used in the bore operation process.
Background technology: before exploiting coalfield under coal mine at present, must first the gas in the coal mining scope be carried out to extraction, guarantee the safety in production of coal-face in operation process.During gas pumping, solve the essential measure of current China's coal-mine gas accident, particularly gas explosion, outstanding particularly serious accident.The first step is holed exactly in the extraction process, and boring the time will be measured the orientation of boring, guarantee the accurate location of holing.Existing measuring method is used six cotton ropes exactly, eight nails, plural personnel, before rig, laterally follow closely a line with two nails, center line is vertically with line of nail nail, in the rig back, also to laterally follow closely a line with two nails, center line is vertically with vertical line of nail nail, in addition before and after the rig with boring on schedule, angle angle by design, when the rig tail wins over along the boring nail straight line of drilling rod to design, with the front and back median vertical line, draw straight line again, a nail is on the tunnel equated with center line or cavern's wall, walk crosswise and pull to rig tail place, the angle of the intersection of these two lines is exactly the angle of boring, with special-purpose tilt gauge horizontal survey, go out again the number of degrees of angle.So not only wasted a large amount of manpower and materials, and the angle angle of measuring is inaccurate, has significantly reduced production efficiency.
The utility model content: the utility model has overcome the drawback that current technology exists, a kind of measured angular scale plate, reading piece and dog screw of utilizing is provided, with regard to available vertical, center line and mobile far infrared rays, complete the measurement to drilling hole point mark angle, take measurement of an angle accurately high, improve the speed of angular measurement and the portable laser angle measuring instrument that efficiency is used.
The technical scheme that the utility model technical solution problem adopts is: its movable laser bench 2 use set bolts 3 are movably arranged on measures pedestal 1 front end one side, the plate 4 that takes measurement of an angle is movably placed in and measures middle part on pedestal 1 and movable laser bench 2 by reading piece 5 use dog screws 6, vertical laser far infrared rays emission source 9 is arranged on measures pedestal 1 right-hand member front middle part, middle line laser far infrared rays emission source 11 is arranged on measures pedestal 1 lower-left end front middle part, and mobile laser far infrared rays emission source 10 is arranged on the left section of movable laser bench 2.
The beneficial effects of the utility model are: owing to having adopted unique measurement pedestal and movable laser bench, utilize measured angular scale plate, reading piece and dog screw, with regard to available vertical, center line and mobile laser far infrared rays, complete the measurement to drilling hole point mark angle.And simple in structure, stable performance, the accuracy that takes measurement of an angle is high, has improved speed and the efficiency of angular measurement, has significantly reduced cost of production.
The accompanying drawing explanation: Fig. 1 is front view of the present utility model
Fig. 2 is the top view of Fig. 1
Fig. 3 is the left view of Fig. 1
The specific embodiment: as shown in Figure 1, Figure 2, Figure 3 shows, its movable laser bench 2 use set bolts 3 are movably arranged on measures pedestal 1 front end one side, the plate 4 that takes measurement of an angle is movably placed in and measures middle part on pedestal 1 and movable laser bench 2 by reading piece 5 use dog screws 6, vertical laser far infrared rays emission source 9 is arranged on measures pedestal 1 right-hand member front middle part, middle line laser far infrared rays emission source 11 is arranged on measures pedestal 1 lower-left end front middle part, and mobile laser far infrared rays emission source 10 is arranged on the left section of movable laser bench 2.
As shown in Figure 1, Figure 2, Figure 3 shows, described measured angular scale plate 4 both sides arrange respectively the spacing shifting chute of spacing shifting chute 7, two 7 both sides angle index value 8 are set respectively.
As shown in Figure 1, Figure 2, Figure 3 shows, described measurement pedestal 1 is movably fixed on flexible A-frame by fixing hole 12.
As shown in Figure 2, described measurement pedestal 1 upper right side arranges power switch and infrared emitting switch 13.
As shown in Figure 1, Figure 2, Figure 3 shows, described vertical laser far infrared rays emission source 9, middle line laser far infrared rays emission source 11 and mobile laser far infrared rays emission source 10 are point-blank.
The plate 4 that takes measurement of an angle is inverted in the utility model adjustment, can also be using movable laser bench 2 as the central laser far infrared rays, and use as mobile laser far infrared rays measuring a pedestal 1.
It is 90 degree that the utility model is measured maximum angle.
Operating principle of the present utility model is: portable laser angle measuring instrument is fixed on flexible A-frame, opening power, mobile movable laser bench, vertical laser far infrared rays is aimed to the vertical marker of tail, middle line laser far infrared rays is aimed at center line hole mark, mobile laser far infrared rays is aimed at the drilling hole point mark of institute's operation, press the scale on measuring instrument, with the laser infrared line from the rig tail, with center line three light vertical with rig and rig tail, determine the angle position, can complete the measurement to the boring angle.
