起重机臂架清洗装置机构设计及试验研究
Design and experimental study on the mechanism of the cleaning device of the crane boom
摘要
Abstract
Remanufacturing is a key technology to restore the original size and performance of the waste components.For this pur-pose,the remanufacturing of used car crane formulate a kind of new arm washing equipment which can adapt to different shapes of surface and different heights.The relationship between the jet striking force and the adhesion of the paint film was analyzed.The effects of the spray nozzle pressure and the feed rate of the washer on the cleaning efficiency were studied.Application of high ef-ficient washing technology with high pressure water jet to boom cleaning test.The experimental results show that the cleaning de-vice can accomplish the cleaning task well when the nozzle diameter is 0.4 mm,the target distance is 20 mm,the outlet pressure is 180 MPa,and the cleaning device travel speed is 0.6 m/min,and meets the requirements of the crane boom of construction ma-chinery.Manufacturing cleaning process requirements.This washing equipment can solve the problem of cleaning the surface of auto-crane arms,which lays the foundation for the subsequent nondestructive testing and repairing of the crane arms.关键词
