It requires " the loading plate alignment circled positions deviation of drop hammer deflection meter to be no more than 30mm, two instruments are curved to same point in 2008
10min is not to be exceeded in the time interval of heavy test." cannot achieve.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of drop hammer deflection meter drop point laser locating apparatus, energy
It is enough it is more accurate drop hammer deflection meter position of dropping hammer is positioned, overcome using under original positioning method, because of personnel
Improper the case where causing drop hammer deflection meter test position to be difficult to precise positioning is commanded, to influence the accuracy of Comparability test.
The technical solution that the utility model is taken are as follows:
A kind of drop hammer deflection meter drop point laser locating apparatus, including positioning the LED laser projector, monitoring system, first
The positioning LED laser projector, the second positioning LED laser projector are symmetrically distributed centered on loading plate, position LED laser
The projector can project image on test road surface after opening, and forming position confirms target shape ring.
The monitoring system includes camera, monitor screen, and camera connects monitor screen by transmission line, and camera is for clapping
Take the photograph that location confirmation target shape ring, drop hammer central projection circle；Monitor screen confirms that target shape ring, drop hammer central projection circle for observation position.
The first positioning LED laser projector, the second positioning LED laser projector are located at the carrier vehicle of drop hammer deflection meter
Bottom is located at same straight line with the three that drops hammer, and the straight line is vertical with the carrier vehicle measurement direction that drops hammer.
The camera is located at the carrier vehicle bottom of drop hammer deflection meter, and monitor screen is mounted in driver's cabin.
The positioning LED laser projector can prejudge test point position of dropping hammer, and as the central projection circle that drops hammer, shape
At location confirmation target shape ring, the location confirmation target shape ring circularizes distribution, and adjacent rings semidiameter is 5cm.
The location confirmation target shape ring is equipped with graduation mark, and the zero graduation of graduation mark is arranged in the central projection circle that drops hammer, in advance
Sentence the test point outer ring that drops hammer to show in shiny red laser projection.
A kind of drop hammer deflection meter drop point laser locating apparatus of the utility model institute, has the advantages that
(1), there is location confirmation target shape ring scale to show, driver can be assisted intuitively to understand and according to position deviation
It is adjusted, avoids influence of the human factor to test parameters；
(2), test operation is simplified, is improved work efficiency；
(3), for compared to sense organ preestimating method, subgrade and pavement rebound deflection is carried out using device provided by the utility model
Detection test, test result are more accurate.
(4), drop hammer type flexure and backman beam flexure will do point-to-point comparison, it is desirable that the two alignment position deviation does not surpass
30mm is crossed, 10min is not to be exceeded to the time interval of same point deflection test in two instruments.In practical operation have to someone under
Face goes observation to tell driver again on all fours, extremely time-consuming and laborious.After utility model device, not only driver can be carried out reality
When monitor, there are also scales to carry out alignment adjusting, intuitive and convenient.
