Definitions
- the present invention relates to a test apparatus, and more particularly to a bladder type road surface accelerated loading test apparatus. Background technique
- the road surface accelerated loading test equipment is a special equipment for testing and detecting pavement materials and structures.
- the existing rolling device of the road surface acceleration loading test equipment mainly adopts a reciprocating and circulating rolling type to reproduce the actual rolling operation of the vehicle on the road surface, and the rolling pressure of the road iti is mostly from the counterweight. Or hydraulic pressure, its structure is complex, low efficiency, high energy consumption, and high noise. Summary of the invention
- the present invention is directed to the deficiencies of the prior art, and provides an accelerated loading test device that can better reproduce the rolling condition of the road surface during actual operation of the vehicle, and has an efficient, energy-saving and environmental protection function.
- An airbag type road surface accelerated loading test device comprises a body, a rolling wheel and a pneumatic suspension system, wherein the air controlled suspension system is composed of an air bag, a ventilation bolt, a spoke, a valve, a connecting shaft and a swing frame,
- the air bag, the ventilating bolt, the spoke, the valve and the connecting shaft constitute an air storage space that can communicate with each air bag, and the air storage space is inflated or deflated by the air nozzle, and the swing frame is hinged to the spoke.
- one end of the airbag is fixed on the spoke by a vent bolt, and the other end is fixed to the swing frame by bolts, and the spoke is welded on the connecting shaft, and the spoke assembly is composed of the spoke, the swing frame and the connecting shaft, and the rolling wheel is at the spoke.
- the component is driven to rotate around the connecting shaft, and one of the roller compactors is in contact with the experimental road surface under the joint action of the airbag and the spoke assembly, and the rolling test is performed on the road, and the plurality of crushing wheels are sequentially continuous in the airbag. Rolling test on the road surface under the joint action of the spoke assembly.
- the spokes are disposed in the body, and the spokes are driven by the motor through the V-belt and the reducer. move.
- the airbag type road surface accelerated loading test device has a gas storage space of the air suspension system consisting of an air bag, a ventilation bolt, a spoke, a valve, and a connecting shaft, and the entire gas storage space is filled and discharged through the valve, and The gas pressure of the system controls the crushing pressure of the roller on the experimental pavement.
- the above-mentioned airbag type road accelerates the loading test device.
- the roller compactor presses the airbag by the swing frame and the spoke hinge to pressurize the airbag, and the spoke assembly drives the road surface to carry out the rolling test.
- the airbag type road surface accelerated loading test device of the invention is operated by a motor through a V-belt drive, and the reducer drives the spoke assembly to rotate around the communication shaft, and the plurality of roller compactors are driven by the spokes and the swing frame of the spoke assembly, in turn
- the airbag and the spoke assembly work together to perform a rolling test on the road surface.
- the airbag type road surface accelerated loading test device of the present invention has the following beneficial effects:
- the invention adopts the rolling type of the airbag type road surface accelerated loading, can better reproduce the rolling condition of the road surface during the actual running of the vehicle, and can make the structure simple, the work is reliable, and the noise is low.
- the invention adopts a spoke, a swing frame and a connecting shaft to form a spoke assembly, which drives a plurality of rolling wheels to rotate, and sequentially performs a rolling test on the road surface under the joint action of the air bag and the spoke assembly, thereby improving the test efficiency and reducing the test efficiency. Energy consumption.
- FIG. 1 is a schematic front view showing the structure of an airbag type road surface accelerated loading test device
- FIG. 2 is a schematic left side view of the airbag type road surface accelerated loading test device. Description of the reference numerals
- the airbag type road surface acceleration loading test device of the present invention comprises a machine body 7, a crushing wheel 1 and a pneumatic control suspension system, and the air control suspension system comprises an air bag 2, a ventilation bolt 5, The spoke 6, the valve 10, the communication shaft 11 and the swing frame 3 are formed.
- the air bag 2, the ventilating bolt 5, the spoke 6, the valve 10 and the communication shaft 1 1 constitute a gas storage space that can communicate with each air bag, and the gas storage space is inflated or deflated by the valve 10, and the gas pressure of the system is used. Control the rolling pressure of the roller 10 on the experimental road surface.
- the spokes 6 are hinged to the pendulum frame 3 through the pin shaft, and the spokes 6, the pendulum frame 3 and the communication shaft 1 1 constitute a spoke assembly, and the spoke assembly drives the plurality of roller compactors 1 to rotate clockwise.
- the rolling test was carried out on the road surface under the joint action of the airbag 2 and the spoke assembly.
- the body 7 of the above-mentioned accelerated loading test device is provided with a control leg 9 and a stepping motor 8.
- the control leg 9 By adjusting the control leg 9 to adjust the rolling length of the rolling wheel 1 to the road surface, the gas pressure in the gas storage space can also be changed.
- the accelerated loading test device is simple and convenient to process, and can be processed according to the drawings shown in the specification.
