The winch braking device comprises a hydraulic source, a valve group, a water cooling brake and a controller, and the controller is configured to output a corresponding control signal to the valve group based on the target rotating speed of a winch drum; the valve group is arranged on a hydraulic pipeline between the water-cooled brake and a hydraulic source, and is configured to convey corresponding liquid flow to the water-cooled brake based on a control signal provided by the controller; and the water-cooled brake is configured to provide corresponding braking force to the winch drum based on the liquid flow conveyed by the valve group so as to control the rotating speed of the winch drum. The invention further discloses a workover rig comprising the winch braking device.
本发明公开了一种绞车制动装置,包括液压源、阀组、水冷制动器以及控制器,所述控制器配置为基于绞车卷筒的目标转速向所述阀组输出相应的控制信号;所述阀组设置在所述水冷制动器与液压源之间的液压管路上,并且配置为基于由所述控制器提供的控制信号向所述水冷制动器输送相应的液流;所述水冷制动器配置为基于由所述阀组输送的液流向绞车卷筒提供相应的制动力,以控制绞车卷筒的转速。本发明还公开了一种包括该绞车制动装置的修井机。
