The invention relates to the technical field of hydraulic winches, and discloses a constant tension winch hydraulic system which comprises a control integration assembly, a lifting speed reduction assembly is arranged on the left side of the outer end of the control integration assembly, a winch is arranged on the inner side of the control integration assembly, and a hydraulic valve body assembly is arranged on the left side of the front end of the control integration assembly. A protection plate is arranged on the right side of the lower portion of the hydraulic valve body assembly, a bottom supporting assembly is arranged below the protection plate, and a forward and reverse motor is arranged at the right end of the winch. The expansion disc is driven by the abutting block at the outer end of the speed reducer to expand to support the non-return ring, the non-return ring is expanded outwards to brake the winch, when the winch works, the tension of a twisted rope can be controlled by the sensor to change within a certain range according to the change of the tension of the twisted rope, and when the tension exceeds the range, the sensor acts to control the winch to work. And the control system sends a rope winding or unwinding command until the tension returns to the set range, so that dangerous conditions are prevented.

    本发明涉及液压绞车技术领域,且公开了一种恒张力绞车液压系统,包括控制整合组件,所述控制整合组件外端的左侧设有起升减速组件,所述控制整合组件的内侧设有绞盘,所述控制整合组件前端的左侧设有液压阀体组件,所述液压阀体组件下方的右侧设有防护板,所述防护板的下方设有底部支撑组件,所述绞盘的右端设有正反电机。通过减速器外端的抵块带动扩增盘扩大对逆止圈进行支撑,让逆止圈向外扩张对绞盘进行刹车制动,让绞车在工作时,可以根据绞绳张力的变化,通过传感器控制绞绳张力在一定范围内进行变化,当超过这个范围时传感器动作,控制系统发出收绳或放绳命令,直至张力重新回到制定范围内,防止危险情况的发生。
