Description
Technical field
The utility model relates to the oil-well drilling equipment technology, specifically is a kind of band brake automatic driller.
Background technology
In the drillng operation, for detecting the suspending weight value of hook loading in real time, oil-well rig all is equipped with a wire rope to walk around pulley between drill string and the hook, one end is connected on the winch drum brake strap, the other end is fixed on the frame by dead line anchor, the pulling force sensor of measuring suspending weight is installed on the wire rope near the dead line anchor place, the pulling force signal that pulling force sensor is gathered embodies with the suspending weight value, because suspending weight value and the pressure of the drill value have certain conversion relation, can directly show the suspending weight value on the instrument board, and calculate the pressure of the drill.Existing band brake automatic driller, it is the driller provides setting according to drill bit and formation rock situation the pressure of the drill value, compare according to the pressure of the drill value that suspending weight calculated of instrument board demonstration and the pressure of the drill value of setting again, the pressure of the drill difference relatively converts the gas signal to, rotating speed by control motor behind the power amplifier again, and then the brake torque of control band brake reaches the purpose of control bit speed.The principal character of this automatic bit feed mode is machinery control, and can use must have winch to place on the rig floor time, usually can produce the pressure of the drill fluctuation.
The utility model content
The purpose of this utility model provides a kind of band brake automatic driller, has exactly ground control brake strap degree of tightness and drill string and transfers, and realizes the advantage that constant voltage and constant speed are crept into automatically.
The technical scheme that the utility model adopted is:
A kind of band brake automatic driller, pulley one end that one wire rope is walked around between drill string and the hook is connected on the winch drum brake strap, the other end is fixed on the frame by dead line anchor, pulling force sensor is installed on the wire rope near the dead line anchor place, it is characterized in that: also comprise guidance panel, PLC control device, drive unit, executing agency;
Touch-screen as upper supervision usefulness is installed on the described guidance panel, power supply indicator, control box internal heater relay indicating light, alarm lamp also is installed on the guidance panel, is respectively applied for fault and resets, remove brake, the system anxious button that stops operating, the mode of operation that is used for automatic bit feed are switched under significant trouble or dangerous situation rotary switch, heater rotary switch, power supply switch knob switch, the PLC rotary switch of powering.
Described drive unit adopts servo-driver;
Described executing agency is made of servomotor, brake steel wire rope, the tight spring of stopping, servo-driver is connected with the servomotor cable, the brake steel wire rope is connected in servomotor output axle head and brake lever position, stop tight spring and brake steel wire rope is rightabout one end and is fixed in the brake lever position, and the other end is fixed in frame;
Described touch-screen is connected with PLC control device communication port by connection, each button, each rotary switch are connected with the digital quantity input module of PLC control device respectively, each indicator lamp is connected with the digital quantity output module of PLC control device respectively, pulling force sensor is connected with the analog quantity input module of PLC control device, and servo-driver is connected with PLC control device communication interface by connection.
Operating principle:
Guidance panel is controlled the setting of various function conversions, parameter, and realizes visual, comfortableness operation interface.
Record drill string suspending weight data in real time by pulling force sensor, the data acquisition of suspending weight is equivalent to obtain to the pressure of the drill real-time data acquisition, the suspending weight data of collection input to the PLC control device, and the parameter acquisition that is used for control automatically calculates.
The PLC control device is done real-time data operation, analysis and processing to the suspending weight data of gathering, with accessory drive and executing agency.
Executing agency adopts servomotor, acts on band brake lever part by the brake steel wire rope, becomes opposite balance pulling force with the tight spring of stopping, and the outstanding load of holding of winch is controlled.The stepping of PLC control device and servo-driver control servomotor, servo-driver is accepted the pulse train sent from the PLC control device by the pulse input interface, carry out the control of speed and position, can realize the accurate positioning control of servomotor, have higher response speed.Finish the control of servo-driver operation and the output of real-time status by the digital quantity interface signal, the reaction torque and the displacement of control brake steel wire rope and brake spring, realize being with the exactly of the elasticity of stopping to regulate, accurate fast the adjustment is with the brake torque of stopping, and realizes intelligent brake and evenly send brill.
The actual suspending weight of drilling tool (PV) that pulling force sensor is collected, after comparing, obtain deviation e=SV-PV with suspending weight setting value (SV), de/dt tries to achieve deviation variation rate ec to the e differential, with e and ec input fuzzy control link FUZZY, calculate regulated value u, with the source of this value, take this servomotor is positioned control as the servo control mechanism control rate.The pulling force pulling brake lever of servomotor pulling brake steel wire rope produces corresponding brake weight, and the actual suspending weight of drilling tool is changed, and forms the closed-loop control of suspending weight.Under the normal condition, when disturbance factor affacts when making the PV value depart from the SV value largely on the drilling tool, the fuzzy control adjuster produces a suitable regulated quantity u PV value is withdrawn near the SV value again, has realized that so just permanent suspending weight creeps into.Because the pressure of the drill value always equals the poor of clean suspending weight of drilling tool and actual suspending weight, thereby permanent suspending weight creeps into, and to creep on effect with permanent the pressure of the drill be identical.
Beneficial effect:
1. creep into control: by PLC control device, drive unit, actuating mechanism controls the pressure of the drill, keep permanent the pressure of the drill, evenly send brill, obtained continuous, the level and smooth brill effect of sending, improved rate of penetration simultaneously.
2. guidance panel operation: the conversion of various operating functions is provided with various parameters, and good visual, comfortableness monitoring display operation interface is provided.
3. the system that disposes on the guidance panel is the anxious button that stops operating under significant trouble or dangerous situation, and the driller is hand-operated brake at any time, and transferring and creeping into of control tourist bus reduced driller's working strength greatly.
