Embodiment Construction

[0015] Combine below figure 1 and figure 2 A rotary road acceleration loading experimental device of the present invention will be described in detail below.

[0016] like figure 1 and figure 2 As shown, a rotary road surface acceleration loading experimental device of the present invention has a structure comprising: a casing 1, a machine base 5, a road surface rolling wheel 4, legs 6, a loading track 7, a loading wheel 8, and a speed reducer 9 , V-belt 10, motor 11, shaft 12, bearing housing 13 and rotary assembly, and the rotary assembly is composed of spokes 3, swing frame 2, and shaft 12.

[0017] The above-mentioned rotary assembly is arranged in the casing 1, and the spokes 3 of the rotary assembly are hinged to the pendulum 2 through the pin shaft, and the pendulum 2 drives the road rolling wheel 4 to rotate clockwise, and sequentially rotates between the loading track 7 and the road rolling wheel 4. Under the action of tire deformation, the road surface is rolle...

Abstract

The invention provides a rotary pavement accelerated loading experimental device, which belongs to the field of test equipment, and its structure includes a machine base, a casing, and a rotary assembly. A rotary assembly is arranged on the machine base, and the rotary assembly is driven by a motor through a V-belt drive and a reducer, and the rotary assembly drives the road rolling wheel to rotate in the casing. It is characterized in that the slewing component drives the road surface rolling wheel, and the road surface rolling experiment is carried out under the action of the loading track and the road surface rolling wheel, so as to reproduce the rolling condition of the road surface when the vehicle is actually running, and improve the accuracy of the experimental conclusion and the test results. Another feature of the present invention is that the road surface rolling wheel is driven by the rotary assembly, and multiple road surface rolling wheels successively carry out rolling experiments on the road surface, so that the structure is simple, the efficiency is high, the energy consumption is small, and the noise is low.

Description

(1) Technical field [0001] The invention relates to a test device, in particular to a rotary road surface accelerated loading test device. (2) Background technology [0002] Accelerated pavement loading test equipment is a special equipment for testing and testing pavement materials and structures. The rolling device of the existing road surface accelerated loading test equipment mainly adopts reciprocating and cyclic rolling types to reproduce the rolling condition of the road surface when the vehicle is actually running, and the rolling of the road surface is only once in a reciprocating or cyclical , with complex structure, low efficiency, high energy consumption and high noise. (3) Contents of the invention [0003] The technical task of the present invention is to address the deficiencies of the prior art, and provide a road surface accelerated loading experimental device that can better reproduce the rolling conditions of the road surface when the vehicle is actuall...
