Description
Technical field
The utility model relates to the measurement mechanism of bridge span, particularly, relates to a kind of laser measuring device for measuring of bridge span.
Background technology
Bridge span measurement is a key index of bridge quality testing, and this index is the centre distance of adjacent two pillars of bridge.In the past during this index of curb girder, most employing manually draws steel ruler and tautness meter to measure, and manual control pulling force and range estimation reading, therefore exist the poor and problem of operating difficulties of precision.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of laser measuring device for measuring of easy to use, bridge span that precision is high.
A kind of laser measuring device for measuring of bridge span, it is characterized in that, described laser measuring device for measuring comprises main laser stadimeter, secondary laser range finder, main laser location-plate, secondary laser positioning plate, described main laser stadimeter, secondary laser range finder, main laser location-plate and secondary laser positioning plate are rectangle setting, be located at rectangular four summits respectively, described main laser stadimeter, secondary laser range finder is the symmetrical radial both sides being located at a bridge to be measured pillar respectively, described main laser location-plate, secondary laser positioning plate is the symmetrical radial both sides being located at bridge adjacent struts to be measured respectively.
The side of described main laser stadimeter is provided with the 3rd laser range finder of the spacing measuring main laser stadimeter and secondary laser range finder.
The side of described secondary laser range finder is provided with the 3rd laser positioning plate.
Compared with prior art, the utility model has following beneficial effect: utilize accurate laser range finder to realize accurately measuring of bridge span, consider the error of single equipment simultaneously, adopt three laser range finders, be rectangle setting, use simple Pythagorean theorem computing, draw more accurate bridge span.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
As shown in Figure 1, according to the laser measuring device for measuring of a kind of bridge span that the utility model provides, laser measuring device for measuring comprises main laser stadimeter 11, secondary laser range finder 21, main laser location-plate 3, secondary laser positioning plate 4, main laser stadimeter 11, secondary laser range finder 21, main laser location-plate 3 and secondary laser positioning plate 4 are rectangle setting, be located at rectangular four summits respectively, main laser stadimeter 11, secondary laser range finder 21 is the symmetrical radial both sides being located at a bridge to be measured pillar respectively, main laser location-plate 3, secondary laser positioning plate 4 is the symmetrical radial both sides being located at bridge adjacent struts to be measured respectively.
Carry for the ease of installing, main laser stadimeter 11 is fixed on main laser reference column 1, and secondary laser range finder 21 is fixed on secondary laser positioning post 2.The side of main laser stadimeter 11 is provided with the 3rd laser range finder 12 of the spacing measuring main laser stadimeter 11 and secondary laser range finder 21.The side of secondary laser range finder 21 is provided with the 3rd laser positioning plate 22.
Practical approach of the present utility model is as follows:
Adopt three laser range finders, be rectangle setting, first gather
Main laser stadimeter 11 arrives the distance L1 of main laser location-plate 3,
Main laser stadimeter 11 arrives the distance L2 of secondary laser positioning plate 4,
Secondary laser range finder 21 arrives the distance L3 of main laser location-plate 3,
Secondary laser range finder 21 arrives the distance L4 of secondary laser positioning plate 4,
The distance L5 of the 3rd laser range finder 12 to the three laser positioning plate 22;
Comparison L1 and L3, L2 and L4, use Pythagorean theorem to calculate the theoretical L6 of the 3rd laser range finder 12 to the three laser positioning plate 22;
The position of adjustment main laser stadimeter 11, secondary laser range finder 21, main laser location-plate 3, secondary laser positioning plate 4, the rectangle vertex position becoming standard is arranged, and now L1 is the bridge span of wanted curb girder.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
