For the utility model in use, the utility model is placed on into bridge highest point, regulation level governor 4 causes laser
Rangefinder 9 is horizontal, and then rotates swivel plate 6 so that the position of horizontal rangefinder 9 and the length direction one of bridge
Cause, then open laser range finder 9, open afterwards rotary laser rangefinder 9 up and down so that the laser spots of laser range finder 9
The minimum point of bridge 25 is impinged upon, during rotation, the angle recordings rotated by pointing to groove 11 relative to bevel protractor 10 go out
Carry out laser rays relative to horizontal angle, the length of laser rays is then determined by the number of degrees on laser range finder 9, according to
Laser rays draws angle of the laser rays relative to vertical curve relative to horizontal angle, the angle by laser relative to vertical curve
The length of degree and laser rays, can calculate the right angle vertical edge and right angle horizontal edge of laser rays, and right angle horizontal edge is exactly peak to minimum
The horizontal range of point, vertical edge is exactly distance of the laser emission point to horizontal edge, then according to graduated scale（Ruler, measure air line distance）
Laser emission point now is measured to the distance of supporting plate, because the height of supporting plate is certain, therefore can be drawn sharp
Relative to the height of bridge floor, vertical edge size above subtracts laser spots and draws bridge floor most relative to the height can of bridge floor luminous point
The vertical distance of high point, the slope of bridge can be calculated by the lateral separation between bridge highs and lows and vertical distance
Degree, above Computing Principle are as shown in Figure 3.As shown in figure 4, when the radian of bridge is excessive, laser beam can not be irradiated to minimum point,
Only need to point out one projection plate 26 of placement in the minimum of bridge, laser spots are projected on projection plate 26, now basis
The angle a of laser rays and length calculate laser spots to the lateral separation d and vertical distance e of laser emission point, then measure
Come laser spots height c and laser emission point relative to the height b of bridge 25, subtract Laser emission with above-mentioned vertical distance e
The height b of point can obtain the peak of bridge 25 plus the height c of laser spots
It is lateral separation of the bridge peak to minimum point, is then calculated using the transverse direction and vertical distance of bridge peak to minimum point
Go out the gradient of bridge 25.No matter bridge is how high can easily measure for said apparatus, and plate 26 is projected when setting
When, the height of projection plate 26 only needs laser rays to be mapped to.
The utility model is practical, is adapted to various highly different bridges, measurement is quick, easy to carry.
