Description

Technical Field

[0001] The utility model relates to the technical field of test data acquisition, in particular to a highway traffic engineering test detection data acquisition device. Background Art

[0002] Compactness is one of the key indicators for roadbed and pavement construction quality inspection, which characterizes the density after on-site compaction. The higher the compactness, the greater the density and the better the overall performance of the material. The sand injection method is the main method for measuring compaction on many engineering sites.

[0003] The basic principle of the sand filling method is to use clean and uniform sand with a particle size of 0.30-0.60mm or 0.25-0.50mm to fall freely into the test hole from a certain height, and measure the volume of the test hole according to the principle of constant unit weight (that is, use standard sand to replace the aggregate in the test hole), and combine the moisture content of the aggregate to calculate the actual dry density of the sample.

[0004] In the existing operation, after digging a test hole, a test sand cylinder filled with uniform sand is placed on an electronic scale for weighing, data is recorded, and then it is moved to a tray on the top of the test hole. After the material is dropped, the test sand cylinder filled with the remaining uniform sand is moved back to the electronic scale for weighing, data is recorded, and then it is moved down. Since the test sand cylinder itself does not have a data collection function, the test sand cylinder needs to be moved back and forth, which not only increases the labor intensity of the workers, but also reduces the detection efficiency. Therefore, a highway traffic engineering test detection data collection device is proposed. Utility Model Content

[0007] Furthermore, the synchronous drive assembly includes a motor, and the motor is fixedly installed at the bottom of the annular shell. The driving end of the motor is fixedly connected to a rotating shaft, and the rotating shaft passes through the bottom of the annular shell and extends to the interior and is rotatably connected thereto. A driving gear is fixedly sleeved on the outer surface of the rotating shaft. The motor is the electric drive source of the synchronous drive assembly and is the operating basis of its electric drive.

[0008] Furthermore, the outer surface of the driving gear is meshedly connected with a ring gear, and the ring gear is rotationally connected to the inner wall of the annular shell. The outer surface of the ring gear is meshedly connected with multiple driven gears, which can synchronously drive multiple telescopic legs to move.

[0010] Furthermore, outer surfaces of the plurality of support rods are commonly fixedly connected with a connecting ring, and the connecting ring has a limiting effect on the plurality of support rods to prevent the support rods from rotating.

[0011] Furthermore, handles are fixedly installed on both sides of the outer surface of the sand cylinder body, and the handles have an auxiliary function to facilitate lifting the sand cylinder body.

[0012] Furthermore, a controller is fixedly mounted on one side of the outer surface of the annular shell, and a display screen is mounted on the controller.
