Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] The invention provides an oil drilling rig drawworks control system with three-site operation mode, such as figure 1 As shown, it includes the PLC controller 5 of the drilling rig, and the input end of the PLC controller 5 of the drilling rig is respectively connected with the winch control mode assignment switch 1, the winch body control box 2, the remote mobile control box 3, the driller’s room control box 4 and the hook load Detection unit 11. The output end of the drilling rig PLC controller 5 is respectively connected with a frequency conversion / DC power speed regulating unit 6 , an auxiliary power distribution unit 8 and a disc brake control unit 10 . The input end of the power speed regulating unit 6 is also connected to an AC or DC power supply. When the winch is driven by alternating current, the power speed regulating unit 6...

The invention discloses a petroleum drilling machine winch control system with three-place operation modes. The petroleum drilling machine winch control system comprises a drilling machine PLC, wherein the input end of the drilling machine PLC is connected with a winch control mode assignment switch, a winch body control box, a remote movement control box, a driller house control box and a hook load detection unit respectively; the output end of the drilling machine PLC is connected with a power speed regulation unit, an auxiliary power distribution unit and a disc brake control unit; the output end of the power speed regulation unit is connected with a main driving motor; and the output end of the auxiliary power distribution unit is connected with an auxiliary motor. The invention further discloses a control method of the control system. According to the petroleum drilling machine winch control system with the three-place operation modes, flexible operation of a winch can be achievedthrough three control modes, and safe and convenient operation of the winch under different working condition requirements is met; meanwhile, the three modes can achieve the mutual standby function,and the problems that only driller house operation can be achieved at present and that reliability is low are solved.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment control systems and methods, and in particular relates to an oil drilling rig winch control system with three-site operation mode. The invention also relates to a control method of the drawworks control system of an oil drilling rig with a three-site operation mode. Background technique [0002] At present, oil drilling rigs and workover rigs are equipped with high-power drawworks, which are mainly used as lifting mechanisms for drill strings and downhole tools in the process of drilling and workover, and also as the driving force for lifting derricks and bases. At present, this type of winch operation is only carried out in the driller's room, and there are unsafe or inconvenient problems in the use of related working conditions. For example, when using the winch to lift the derrick and base of the drilling rig, the operator is on the dynamic lifting base When operating in the drill...
