A Comparative Automatic Rutting Tester

Abstract

The invention discloses a comparative automatic wheel tracking tester. The comparative automatic wheel tracking tester comprises a rack, testing vehicles arranged in the rack and a driving device for driving the testing vehicles to move back and forth, wherein at least two testing vehicles are arranged; an object storage platform is further arranged at a part, located below the testing vehicles, of the rack; the object storage platform is detachably connected with a plurality of positioning plates; the two positioning plates form a fixing groove for fixing a concrete test piece. The comparative automatic wheel tracking tester has the advantages and effects that the plurality of testing vehicles are arranged at the upper end of the rack; meanwhile, the object storage platform arranged below the rack can be used for fixing the concrete test pieces with different sizes and the tester can be used for carrying out tests on the concrete test pieces with different types at the same time and carrying out different pressure tests on the whole concrete test piece, so that detection effects, generated under different environments, different types and different pressure, on the concrete test pieces can be more rapidly and directly compared.

Description

technical field [0001] The invention relates to the field of concrete pavement detection equipment, in particular to a comparative automatic rutting tester. Background technique [0002] At present, the known asphalt pavement rutting simulation test device is mainly composed of a test box and an industrial computer. The test box is composed of a power switch, a heater, a test wheel, a driving motor for the test wheel, a jack, a counterweight, a test piece fixing frame, a temperature sensor, a displacement sensor, a crank, and a box. Put the well-developed test piece into the test piece fixing frame and lock it. After the temperature is constant, use the hand crank to lower the counterweight so that the test wheel fully contacts the test piece, so that it is always in a downward pressure state. Adjust the displacement sensor up and down, and lock the displacement sensor. Start the industrial computer and click the test start button on the menu to proceed. During the test, ...

[0003] For example, the Chinese patent "A Rutting Tester for Simulating Sunlight Environment" with the notification number CN203365220U has the above-mentioned structure, but the current rutting tester can only test a single block, when it is necessary to compare the concrete components of different components When comparing pavement or pavement with the same composition, multiple inspections are required, and the detection environment during the experiment also needs to be consistent. Therefore, there is an urgent need for a detection equipment that can selectively detect
