起重吊车液压系统泄漏故障研究
The design method of loading control system of derrick car based on ADμC824BS was introduced in this paper, the hardware principle block diagram and software flowchart of the control system were presen- ted.
介绍了以ADμC82 4BS微控制器为核心的起重车载荷控制系统的设计方法 ,给出了系统硬件原理图和软件流程图。
Using the object oriented Visual Basic language and calling software AutoCAD,it is successfully in this paper that the whole designing process for crabs of general bridge cranes from 5 to 125 tone can be realized from calculation,the automatic output of design manuals to the automatic planning and drawing of crab′s assembly maps.
研制成的软件—CrabCAD ,极其有效地提高了起重小车的设计质量和设计效
The structure of crab should ensure even load on every wheel and hook lowering normally.
缆索起重机的承载索应选用外层密封的钢丝绳,起重绳、牵引绳选用耐磨及抗弯曲性能好的瓦灵顿型或面接触钢丝绳;起重小车的结构应保证各行走轮承载均衡,吊钩正常落下;固定张开式承马的托轮臂应能平缓张开和关闭,保证起重小车能正常跨越及起重绳、牵引绳不会从托轮上滑脱。
