Rut sample forming machine with rotatable press roll

Abstract

The invention provides a rut sample forming machine with a rotatable press roll. The rut sample forming machine comprises a power distribution cabinet and a control cabinet fixed at the upper end of the power distribution cabinet. The bottom of the control cabinet is connected to the press roll, which is uniformly provided with multiple movable holes. The upper end face of the press roll is detachably provided with a fixed plate, the bottom of which is fixed with spheres. The spheres can be rotatably mounted in the movable holes. Volume of the movable holes is 2 / 3 of volume of the spheres. Thus, the press roll can be rotatably connected at the bottom of the fixed plate. When the press roll swings through a bearing, swinging of the press roll can be realized. Asphalt can be prevented from splashing and burning humans, and nonuniform press-rolling of asphalt can be avoided to the maximum. Therefore, accuracy of test effects is raised to the maximum.

Description

technical field

[0001] The invention mainly relates to the technical field of rut forming machines, in particular to a rut sample forming machine with rotatable rolling wheels. Background technique

[0002] The hydraulic rutting sample forming machine is mainly used for rolling and forming asphalt mixture during rutting test, and can also be used for making wheel-rolling samples for other physical performance tests of asphalt mixture.

[0003] In the existing rut sample forming machines, the fixed structure of the pressure roller is adopted, and the rolling process of the pressure roller on the asphalt is realized by the bearing swing; the forming machine with this structure will not only cause the asphalt At the same time, due to the fixed and non-steering structure of the pressure roller, when the forming machine rolls and forms the asphalt, the asphalt on the pressure table and the position away from the pressure roller will be unevenly pressed, thus affecting the test r...
