Hydraulic control system of breaking hammer and engineering machinery
The invention discloses a quartering hammer hydraulic control system and engineering machinery, and the system comprises an oil inlet path which is used for connecting an oil inlet of an excavator quartering hammer; the oil return path is used for being connected with an oil return opening of the breaking hammer; the oil inlet end and the oil outlet end of the rebound pressure relief oil way are connected with the oil inlet oil way and the oil return oil way respectively; when the pressure of the oil inlet meets the rebound pressure relief condition, the rebound pressure relief oil way is in a communicated state; and when the pressure of the oil inlet does not meet the rebound pressure relief condition, the rebound pressure relief oil way is in a closed state. Abnormal high pressure formed by rebounding can be relieved through the rebounding pressure relief oil way, the loaded condition of a hydraulic system is greatly improved, and the reliability of the system is improved.
本发明公开了一种破碎锤液压控制系统和工程机械，该系统包括：进油油路，用于连接挖掘机破碎锤的进油口；回油油路，用于连接破碎锤的回油口；反弹泄压油路，其进油端和出油端分别连接进油油路和回油油路；当进油口的压力满足反弹泄压条件时，反弹泄压油路处于连通状态；当进油口的压力不满足反弹泄压条件时，反弹泄压油路处于封闭状态。本发明通过反弹泄压油路能够将反弹形成的异常高压泄掉，大大改善液压系统的受载情况，提升系统可靠性。
