Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

Can know by figure 1 to figure 4, an asphalt rut testing machine, including bottom plate 1, be connected with roof 3 through stand 2 on the bottom plate 1, rotate on the bottom plate 1 and be provided with test board 4, rotate on the roof 3 and be provided with accessory plate 5, be connected with four guide pillars 6 around accessory plate 5 and test board 4, roof 3 below is fixed with pneumatic cylinder 7, pneumatic cylinder 7's telescopic boom articulates there is track board 8, is equipped with the lantern ring 9 that cup joints with guide pillar 6 on the passageway board, track board 8 below slidable mounting has wheel 10.

When the utility model is used, the utility model,

the asphalt test piece is placed on the test board 4 to be fixed, the test board 4 is adjusted to a required angle, the hydraulic cylinder 7 pushes the track board 8 to move downwards, and because the lantern ring 9 of the track board 8 is sleeved with the guide pillar 6, the angle of the track board 8 is the same as the angle of the test board 4, the acting force of the hydraulic cylinder 7 is downward all the time, the gravity borne by the vehicle in the form process is simulated, and the wheel 10 performs a rutting test on the asphalt test piece through reciprocating movement below the track board 8.

For avoiding the interference of the test board 4 and the bottom board 1, the bottom board 1 is provided with a groove 11 below the test board 4, similarly, a abdicating groove is also arranged in the top board 3, the interference generated when the auxiliary board 5 rotates can be avoided, a cavity 12 is arranged in the bottom board 1, a fan-shaped worm wheel 13 is coaxially fixed in the cavity 12 by a rotating shaft of the test board 4, a worm 14 meshed with the worm wheel 13 is arranged on the bottom board 1 in a rotating manner, the end part of the worm 14 extends out of the bottom board 1, the worm 14 is rotated, the worm wheel 13 is controlled to rotate, so that the inclination angle of the test board 4 is adjusted, due to the self-locking structure of the worm wheel 13 and the worm 14, after the adjustment is completed, under the condition that the worm 14 is not rotated, the test board 4 can be kept stable.

In order to keep the guide posts 6 in a vertical state, the auxiliary plate 5 is the same as the test plate 4 in size, the guide posts 6 are connected to the same positions on the auxiliary plate 5 and the test plate 4, the connection positions of the guide posts 6, the auxiliary plate 5 and the test plate 4 can rotate, namely the guide posts 6, the test plate 4, the guide posts 6 and the auxiliary plate 5 form a parallelogram structure, the guide posts 6 can always keep the vertical positions unchanged, the track plate 8 is connected with the guide posts 6 through the lantern rings 9, and when the angle of the test plate 4 changes, the distance between the guide posts 6 changes, so that the angle of the track plate 8 changes.
