The invention discloses a single-cylinder bolt control system and a crane, the single-cylinder bolt control system comprises a cable drum, a power unit, a bolt mechanism and a telescopic oil cylinder, the power unit comprises a motor, a hydraulic pump and a control valve group, the motor is connected to the hydraulic pump to drive the hydraulic pump, the hydraulic pump is connected to the control valve group, and the telescopic oil cylinder is connected to the control valve group. The power unit is arranged on the outer side wall of the telescopic oil cylinder, and the power unit is arranged on the outer side wall of the telescopic oil cylinder. According to the single-cylinder bolt control system and the crane provided by the embodiment of the invention, the processing difficulty of the oil cylinder can be greatly reduced, the oil consumption of low-temperature oil is small, and the cost is low; the problems of pin ejection, core tube instability and automatic forward extension of the telescopic oil cylinder caused by volume change of the core tube are avoided; and the system flow can be reduced, so that the hydraulic pump is small in size and light in weight.
本发明公开一种单缸插销控制系统及起重机,该单缸插销控制系统包括电缆卷筒、动力单元、插销机构和伸缩油缸,动力单元包括电机、液压泵和控制阀组,电机连接于液压泵,以驱动液压泵,液压泵连接于控制阀组,以通过控制阀组给插销机构供油以实现插拔销,动力单元设于伸缩油缸的外侧壁。本发明实施例的单缸插销控制系统及起重机中,可大大降低油缸的加工难度,低温油用油量较小,成本较低;避免了芯管自身容积变化导致的销子弹出、芯管失稳、伸缩油缸自动前伸的问题;系统流量可减小,使液压泵体积较小、重量较轻。
