Embodiment
A kind of Varying-slope laser orientation instrument of the present invention, comprises structure-steel framing 1, level crossing 2, altitude circle 3 and two circle levels,
As shown in Figure 1, 2, circle level comprises the ring glass pipe that is equipped with half colored liquid, generally there is red liquid, two circle levels vertically arrange and are fixed in structure-steel framing 1, two circle levels are orthogonal, wherein, circle level I4 fixes along structure-steel framing 1 left and right directions, and circle level II 5 is fixed along structure-steel framing 1 fore-and-aft direction.
Structure-steel framing 1 is made up of the square-tube type metal of one section of 20cm, for stationary annular level, level crossing 2 and altitude circle 3.Two circle levels are fixed on inside structure-steel framing 1, keep motionless with structure-steel framing 1, and wherein, circle level I4 is used in reference to the horizontal direction line illustrated along tunneling direction, and circle level II5 is used in reference to the horizontal direction line that drift section direction is shown.
As shown in Figure 2, described level crossing 2 is arranged in the horizontal direction, be fixed in the middle part of level crossing 2 be supported in structure-steel framing 1 two ends along on the horizontally disposed transverse axis 6 of structure-steel framing 1 fore-and-aft direction, altitude circle 3 is vertically fixed on transverse axis 6.
Transverse axis 6 rotates for supporting plane mirror 2 and altitude circle 3 in the vertical direction.Level crossing 2 can around transverse axis 6 rotating 360 degrees, for reflecting the laser sent with refractive laser director.Altitude circle 3 carves graduated circular metal dish by one piece, and be fixed as one with level crossing 2 and transverse axis, its position of center line is designated as 0 degree and overlaps with the minute surface of level crossing 2.
As shown in Figure 2, structure-steel framing 1 lateral surface is fixed with vertical braking spiral 7, vertical braking spiral 7 comprises one and is fixed on the support with screw on structure-steel framing lateral surface and the screw through screw, and during rotary screw, the end that screw can extend structure-steel framing 1 with transverse axis 6 is locked.The small rotation of level crossing 2 at vertical direction can be realized by rotating, and braking level crossing 2, make it at will not rotate.
As shown in Figure 1, 2, described structure-steel framing 1 top is fixed with two horizontal final motion screws 8 arranged along structure-steel framing 1 fore-and-aft direction, fixed tray 9 is provided with above horizontal final motion screw 8, horizontal final motion screw 8 comprises a foot screw, structure-steel framing 1 top is fixed in foot screw lower end, and fixed tray 9 is fixed in upper end.Horizontal final motion screw 8, for adjustment structure frame 1, makes the colored liquid face of the circle level II5 on structure-steel framing 1 parallel with the minute surface of level crossing 2, makes transverse axis 6 and plane-parallel.Fixed tray 9 is made up of one piece of sheet metal, is fixed on back for apparatus of the present invention.
Below principle of work of the present invention is described.
As shown in Figure 3, when tunnel is normally tunneled, to be put at A, B, C by survey crew and establish laneway midline point, and after A point, laser orientation instrument 10 is installed.Due to need of production, roadway slope change to be realized at D point place.
Traditional solutions is when driving team group is after arrival D point, continues to tunnel forward, always after driving to F place, then has survey crew to put at D, E, F place to establish measuring point, then laser orientation instrument is moved on to D place, continue sensing and tunnel.
After adopting apparatus of the present invention, after driving team group arrives D point, at D point place, Varying-slope laser orientation instrument is installed, adjusts level crossing inclination angle i, then continue to tunnel forward along injection laser.
The computing method of level crossing inclination angle i are:
In Fig. 4, a-incident angle, the b-laser injection gradient, the incident gradient of c-laser, i-level crossing inclination angle
Because a=i+ba=c-i
Therefore i+b=c-i2i=c-b
Therefore i=1/2 (c-b)
Because b, c are given value, so i angle can be asked.
Apparatus of the present invention are below adopted to compare with classic method:
1. construction quality is improved
Classic method, driving team group needs the about 20m distance when not having the gradient to point between blind pick D point to F point.Because if the dot spacing of D, E, F is too little, the error in pointing of laser orientation instrument can be comparatively large, so this roadway gradient of 20 meters cannot ensure by design and construction.
The present invention just can install Varying-slope laser orientation instrument in driving team group afterwards more than D point 1 ~ 2 meter, avoids the excavation work not having the gradient to point to.
2. surveying work amount is saved
Classic method, after digging D point 20 meters, carries total powerstation, tripod, the instruments such as prism by measurement group (at least 4 people), puts and set out D, E, F point, and calculate each point height, and then reinstall laser orientation instrument.
The present invention due to the laser gradient of the laser orientation instrument at A, B, C place known, calculate level crossing inclination angle i, adjustment perpendicular dish reading, complete and become slope and point to.This work only needs a people just can complete.
3. the time effects to driving team group is reduced
Classic method, completes putting of three measuring points and establishes the needs time of 60 ~ 90 minutes.
The present invention, by a people, just can complete for 10 ~ 20 minutes.
