The invention belongs to the field of engineering machinery, and particularly relates to boom equipment and a hydraulic control system thereof. The hydraulic control system comprises a hydraulic actuator, a main reversing valve, a heating switching valve and a controller, wherein the hydraulic actuator is used for driving a boom section of boom equipment; the main reversing valve is used for switching and controlling the action of the hydraulic actuator and comprises a main oil inlet and a main oil outlet on one side and a working oil port on the other side; the heating switching valve is arranged in an actuator working oil path between a working oil port of the main reversing valve and the hydraulic actuator; the controller is used for controlling the heating switching valve, so that the working oil way of the actuator is cut off, and the main oil inlet is communicated with the main oil outlet. According to the arm support equipment, when other arm supports are controlled through the controller, knuckle arm pipeline heating and heating of pipeline oil liquid of the knuckle arm to be controlled can be synchronously carried out, and the response speed is increased when the knuckle arm is actually controlled. The cantilever crane equipment is more suitable for cold regions, and the regional universality is high.
本申请属于工程机械领域,具体地,涉及一种臂架设备及其液压控制系统。液压控制系统包括用于驱动臂架设备的臂节的液压执行器、主换向阀、加热切换阀和控制器,主换向阀用于切换控制液压执行器的动作并包括一侧的主进油口和主出油口以及另一侧的工作油口;加热切换阀设置在主换向阀的工作油口与液压执行器之间的执行器工作油路中;控制器用于控制加热切换阀,使得执行器工作油路截止且主进油口与主出油口导通。本申请的臂架设备可利用控制器,在操控其他臂架时,可同步进行节臂管路加热,加热即将操控节臂的管路油液,待实际操控节臂时,响应速度增加。臂架设备也更能适于寒冷地区,区域通用性强。
