Circulating driving device for highway pavement accelerated loading test system

Abstract

The invention relates to the technical field of highway pavement accelerated loading tests and particularly relates to a circulating driving device for a highway pavement accelerated loading test system. The device comprises a guide rail; the guide rail is fixed on an outer frame; a chain wheel is fixedly installed in the middle of the guide rail; six annular supporting frames which are distributed at intervals are arranged on the chain wheel; and a front supporting plate is arranged at the front end of the annular supporting frame. The circulating driving device for the highway pavement accelerated loading test system has the beneficial effects that through cooperation of a movable side plate and an electric telescopic rod, coarse adjustment of the length of an inner cavity of the annularsupporting frame is achieved, the space in the annular supporting frame is suitable for mounting of a loading wheel, the steps of dismounting and mounting are reduced, the replacement process is simplified, and the detection efficiency is improved; the adjusting support is matched with a hydraulic cylinder, so that fine adjustment of the inner cavity space of the annular supporting frame is achieved, the situation in which the vibration amplitude is increased due to the fact that the inner space is too large is prevented, meanwhile, the position of the loading wheel is adjusted through the hydraulic cylinder, and linear loading is achieved through contact between the loading wheel and the ground.

Description

technical field [0001] The invention relates to the technical field of highway pavement accelerated loading test, in particular to a circulation drive device for a highway pavement accelerated loading test system. Background technique [0002] In order to consider the pavement data detection of the pavement in service, the pavement acceleration loading test system is usually used, which uses the pressure on the loading wheel installed on the sprocket to simulate the impact data of vehicles and other vehicles on the road surface , At the same time, it is convenient to simulate the weather to realize the purpose of real-time detection. [0003] In the process of experimental testing, it is necessary to replace different loading wheels to simulate the impact of different vehicles on the road surface. Due to the different sizes of tires, when installing and replacing, it is necessary to completely disassemble the annular support frame and then reassemble it to suit the road surf...

Problems solved by technology

[0003] In the process of experimental testing, it is necessary to replace different loading wheels to simulate the impact of different vehicles on the road surface. Due to the different sizes of tires, when installing and replacing, it is necessary to completely disassemble the annular support frame and then reassemble it to suit the road surface. The size of the loading wheel is matched, which reduces the efficiency of installation and replacement, the replacement process is cumbersome, the installation is difficult, and it cannot meet the rapid detection of multiple sets of data

[0004] To this end, a cyclic driving device of a highway pavement accelerated loading test system is provided to solve the problem of adaptation between the outer frame of the driving device and the loading wheel
