in the figure: 1. the device comprises a detection drill steel 2, an angle measuring instrument 3, a mounting hole 4, a laser range finder 5, a shell 6, a control switch 7, a display screen 8, a handle 9, a loose paving structure layer 10 and a substrate.
Detailed Description
The present invention will be further described with reference to the following examples.
A handle 8 is fixed to the lower rear end of the housing 5.
Firstly, a handle 8 is held by hand, then the detection drill steel 1 is inserted into a loose structural layer 9 to be detected, the insertion and tamping are repeated for several times to ensure that a hard base 10 is reached, and then the laser range finder 4 and the goniometer 2,0.3 seconds are opened to read data. As shown in fig. 3, L is the thickness of the loose-laid structural layer, L1 and L2 are lengths measured by the upper and lower laser distance meters, L0 is the length of the exposed drill steel, L3 is the length of the inserted drill steel, α is the angle measured by the inclinometer, the length of the inserted loose-laid structural layer is the total length of the detected drill steel 1 minus the average value of the exposed length, and then the data is substituted into the formula: l = [70-L1+ L2/2] × sin α, the thickness of the loose-lay structure layer 9 can be obtained.
All be equipped with mounting hole 3 on the mounting surface of the upper and lower both sides of detecting drill rod 1, laser range finder 4 is fixed in mounting hole 3. The controller is a single chip microcomputer with the model number of 18CZ3457, and the goniometer 2 selects an 88CZ0001 four-inclination sensor three-axis gyroscope. The laser range finder 4 adopts a laser range sensor with the model of TTL/485.
The total length of the steel drill can be input according to the length of the selected detection steel drill 1 before ranging. The data are measured by the two laser distance measuring instruments 4 and the angle measuring instrument 2 and then are directly transmitted to the controller, the controller is used for calculating by the calculator, the calculated data are transmitted to the controller, and the controller is used for controlling the display to directly display the measured thickness value of the loose-laid structural layer 9.
To sum up, the utility model discloses can expose the pine through laser range finder measurement detection drill rod and spread the length, the contained angle of cooperation goniometer measurement drill rod and horizontal plane, then calculate the thickness on pine shop structural layer, do not receive the influence that the drill rod is in vertical state, measure without artifical ruler, more accurate, and operate more convenient and fast, can in time guide the site operation, guarantee follow-up road surface compaction thickness.
