The end of the U-shaped hook can rotate around the bolt. After removing the U-shaped hook from the bottom end of the hook, the U-shaped hook can be rotated to make it deflect to the rear side of the water bucket, which is convenient for putting in and taking out test pieces in the wire basket and avoiding the U-shaped hook from causing obstruction.
[0010] Further, the moving trolley is composed of a vehicle board and a plurality of walking wheels installed on the bottom surface of the vehicle board, and the water bucket is installed on the vehicle board; pushing and pulling the vehicle board can drive the water bucket to move synchronously.
[0011] Further, guide sliders are fixedly arranged on the bottom surfaces of the left end and the right end of the vehicle board, and sliding grooves extending in the front-rear direction and penetrating up and down are formed on the left wing and the right wing of the U-shaped bottom plate. The two guide sliders are respectively in sliding fit with the two sliding grooves; when pushing and pulling the moving trolley, the guide sliders slide in the sliding grooves in the front-rear direction, which can guide the moving direction of the vehicle board and avoid the vehicle board from shaking left and right.
[0012] Further, an annular enclosure is fixedly installed on the top surface of the vehicle board, and the bottom end of the water bucket is inserted into the annular enclosure. The annular enclosure can be used to enclose and fix the water bucket, prevent the water bucket from tipping over when pushing and pulling the moving trolley, and can lift the water bucket out of the annular enclosure upwards, which is convenient for pouring out the water in the water bucket and for disassembling and assembling the water bucket on the moving trolley.
[0013] Further, a push-pull handle is installed on the top surface of the front end of the vehicle board, and it is convenient to push and pull the moving trolley by hand through the push-pull handle.

[0032] The usage method of the detection device in this embodiment is as follows:
[0033] When measuring the density of the asphalt mixture by using a hydrostatic balance, place the specimen on the tray of the electronic balance 1 to weigh the mass in the air. The trolley 5 is located inside the U-shaped bottom plate 2.2. Hang the wire basket 4 on the hook 11 at the bottom of the electronic balance 1 through the U-shaped hook 10, and ensure that the wire basket 4 is immersed in the water in the water bucket 3. After adjusting the water level, zero the electronic balance 1;
[0034] Before removing the trolley 5, after removing the U-shaped hook 10 from the bottom end of the hook 11, the hanging function of the U-shaped hook 10 and the hook 11 is missing, and the wire basket 4 falls in the water bucket 3 until the U-shaped hook parts 9.1 of the two hanging plates 9 are both hooked on the top edge of the water bucket 3, so that the wire basket 4 can be hung on the water bucket 3, preventing the wire basket 4 from falling into the bottom of the water bucket 3 and making it inconvenient to place the specimen in the wire basket 4;
[0035] Grip the push-pull handle 6 by hand and pull out the trolley 5, thereby driving the water bucket 3 and the wire basket 4 out. Rotate the U-shaped hook 10 to make it deflect to the rear side of the water bucket 3. Since the water bucket 3 is pulled out from below the top plate 2.1, the top of the water bucket 3 is no longer blocked by the top plate 2.1 and the electronic balance 1, facilitating the placement of the specimen in the wire basket 4;
[0036] Push the trolley 5 into the inside of the top plate 2.1 so that the water bucket 3 is directly below the electronic balance 1. Re-hook the U-shaped hook 10 on the hook 11 to hang the wire basket 4 and the specimen inside it, and then weigh the specimen to obtain the mass of the specimen in the water;
[0037] Before removing the trolley 5 after the weighing in water is completed, after removing the U-shaped hook 10 from the bottom end of the hook 11, the two hanging plates 9 hang the wire basket 4 on the water bucket 3; after pulling out the trolley 5, take out the specimen from the wire basket 4, wipe the water on the surface of the specimen with a clean, soft and wrung-out wet towel, and then place the specimen on the tray of the electronic balance 1 to weigh the saturated surface-dry mass; finally, calculate the density of the asphalt mixture by using the three mass measurement results.
[0038] When using this detection device to detect the density of asphalt mixture, it is convenient to put the specimen into the wire basket 4 or take the specimen out of the wire basket 4, avoiding being limited by the space distance between the top of the water bucket 3 and the electronic balance 1, and avoiding the obstruction caused by the top of the water bucket 3 and the U-shaped hook 10. The operation of putting and taking out the specimen into and from the wire basket is more convenient.
