The invention discloses an oil supply system for mutually emergency cranes, which comprises two oil supply devices and oil way systems, each oil way system is communicated with one oil supply device and one crane, each oil way system comprises an oil supply pipeline, an oil return pipeline and an oil drainage pipeline, and the three pipelines are respectively provided with a reversing valve for controlling the oil flow direction; when the reversing valve is at the normal position, the pipeline where the reversing valve is located is conducted, and oil is guided to the corresponding pipeline of the other oil way system after reversing; when any oil supply device breaks down, the reversing valve on the oil return pipeline and the oil drainage pipeline connected with the fault oil supply device is reversed, and the reversing valve on the oil supply pipeline connected with the normal oil supply device is reversed, so that the crane connected with the fault oil supply device can obtain oil supply, and the return oil and the drainage oil of the crane are guided to the normal oil supply device; according to the device, when any oil supply device in the two cranes cannot supply oil normally, the oil supply device of the other crane can supply oil.
本发明公开了一种用于互为应急的起重机的供油系统,包括两个供油装置和油路系统,每个油路系统连通一个供油装置和起重机,油路系统包括供油、回油和泄油的管路,所述三个管路上各设有一个用于控制油流向的换向阀;换向阀在常态位时导通其所在管路,换向后将油导流至另一油路系统相应的管路;任一供油装置故障时,故障供油装置连接的回油和泄油的管路上的换向阀换向,正常供油装置连接的供油的管路上的换向阀换向用于使故障供油装置连接的起重机能得到供油并将其回油和泄油导流至正常供油装置;本装置能在两个起重机中任一供油装置无法正常供油时,另一起重机的供油装置能为供油。
