Description
Technical field:
The utility model relates to a kind of measurement railroad track, on height and horizontal both direction with respect to the rail two-dimensional laser measuring instrument of reference line deviation.
Background technology:
At present, what the deviation check of rail both direction was adopted is outstanding rope method, and its measuring accuracy is low, can't satisfy the high-acruracy survey requirement of present high-speed railway to rail.Adopt the method for laser measurement in addition, its emission sighting device adopts the form of eye-observation eyepiece, causes people's kopiopia during measurement easily, wastes time and energy, and the efficient of measurement is low, can't satisfy the high-accuracy high-efficiency rate measurement requirement of present high-speed railway to rail.
The utility model content:
It is convenient that the purpose of this utility model provides a kind of observation, can not cause people's kopiopia, the rail two-dimensional laser measuring instrument that efficiency of measurement is higher.
To achieve these goals, the utility model is made up of emission sighting device and reception image data processing system, the emission sighting device comprises: generating laser, bearing, governor motion, emission level slide, emission height slide, aiming object lens, aiming object lens and generating laser are fixed on the bearing, bearing is fixed on governor motion top, and the governor motion bottom is set with emission height slide and emission level slide; The reception image data processing system comprises: projection objective, CCD digital camera, receive the height slide, receive horizontal slide, the projection objective rear portion fixedly installs the CCD digital camera, the bottom of projection objective is fixed by stent support, and support is fixedly connected on and receives on height slide and the horizontal slide of reception; Being fixedly connected with at aiming object lens rear portion to observe uses CCD display module, governor motion to adopt two-dimentional minute adjustment mechanism.
Because adopting to observe with the CCD display module, the utility model observes aiming to receiving data processing equipment, the image direct convenience shows that when measuring, human eye can direct convenience be observed the CCD display module, remove people's kopiopia of survey crew, improved efficiency of measurement; Adopt accurate two-dimensional adjustment mechanism can make laser facula can accurately aim at the CCD camera of receiving trap, guarantee the precision of reference line, thereby the measuring accuracy of system is reached ± 2mm.Utilize laser ranging can realize to the range observation between emission sighting device and reception and the image data processing system.
Description of drawings:
Fig. 1 is an emission sighting device structural representation of the present utility model.
Fig. 2 is a reception image data processing system structural representation of the present utility model.
Embodiment:
As seen from Figure 1, Figure 2, the utility model is made up of emission sighting device and reception image data processing system, the emission sighting device comprises: generating laser 1, bearing 2, governor motion 3, emission level slide 4, emission height slide 6, aiming object lens 7, aiming object lens 7 and generating laser 1 are fixed on the bearing 2, and generating laser is used for emission of lasering beam.Bearing 2 is fixed on two-dimentional minute adjustment mechanism 3 tops, regulate height and horizontal both directions with two-dimentional minute adjustment mechanism 3, make the visible laser bundle of generating laser emission can accurately aim at the CCD camera that receives image data processing system, thereby a laser alignment baseline is provided.Two dimension minute adjustment mechanism 3 bottoms are set with emission level slide 4 and emission height slide 6, by emission height slide 6 and emission level slide 4 the emission sighting device are fixed on the rail 5.Be fixedly connected with observation at aiming object lens 7 rear portions with CCD display module 8, aim at object lens 7 and observe aiming with observing with 8 pairs of receptions of CCD display module and data processing equipment.The reception image data processing system comprises: projection objective 9, CCD digital camera 10, reception height slide 13, the horizontal slide 12 of reception, the projection objective rear portion fixedly installs CCD digital camera 10, the CCD digital camera receives laser facula and carries out opto-electronic conversion, through image data processing system output data is processed and displayed, measure the relative position of laser facula center on the CCD digital camera.The bottom of projection objective 9 is by support 11 support fixation, and support 11 is fixedly connected on and receives on height slide 13 and the horizontal slide 12 of reception.
