Description
Technical field
This utility model relates to a kind of engineering machinery road roller detection technique field, particularly relates to a kind of steel roller online running-in vibration testing equipment.
Background technology
The road roller that at present construction machinery production factory produces, when dispatching from the factory test, is required for carrying out strict performance test on special skid pad or special Detecting data, has following subject matter during the examination of road:
(1) due to the technical characterstic that road roller engine power is big, noise is big, environment produces sound pollution to external world.
(2) road roller is when road is tried, in order to reach Work condition analogue actual effect, steel wheel part needs starting of oscillation, as a example by the most domestic and international 30 tons of all-hydraulic single-drum road rollers, front axle axle load is 18 tons, when steel wheel is good, exciting force is about 50 tons, after starting of oscillation, steel wheel reaches about 70 tons to test site vertical load, and steel wheel contacts with ground as linear contact lay, stress is concentrated, the destructiveness of road pavement is the biggest, cause test run district road damage serious, test run bad environments, test site each side is required higher, need to build special skid pad, and place needs periodic maintenance, operating cost is high.
(3) road roller is when test site running-in is vibrated, and during the debugging of road roller breakdown judge, requires the highest to the technical merit of test run person, it is desirable to have rich experience accumulates.The most just can carry out failure judgement accurately, complete adjustment and test run.Vehicle dispatch from the factory debugging quality be heavily dependent on anthropic factor.
