介绍一种应用于混凝土泵的新型换向技术,可根据混凝土泵的不同工况自动调节主液压缸和摆缸的换向时机,并设计有应急工作模式,保证接近开关出现故障时,泵送作业仍能继续进行。该项技术的应用能够解决普通电控换向混凝土泵适应负载能力较差和液控换向混凝土泵换向故障率较高的问题,提高施工质量和施工效率。
A new type of commutation technology applied to concrete pump is introduced. According to the different working conditions of concrete pump, the commutation timing of main cylinder and oscillating cylinder can be automatically adjusted, and the emergency working mode is designed to ensure that when the proximity switch fails, Homework can continue. The application of this technology can solve the problems of poor adaptability of ordinary electric controlled reversing concrete pump and reversing failure rate of hydraulic reversing concrete pump, and improve construction quality and construction efficiency.
