Description
Technical field
The utility model relates to the electric-control system of oil drilling, particularly a kind of switching Flying by wire system for top-drive device.
Background technology
Frequency Drive is the technology that a kind of mode by changing input power frequency controls ac motor.The device of Frequency Drive is used to be commonly referred to as frequency converter.Frequency converter is divided into two parts usually: rectification unit and inverter.AC conversion is direct current by rectification unit.Inverter uses electronic switch that DC conversion is become to need the square wave of frequency, and multiple stacking becomes near sinusoidal alternating current, drive motor.
But because Frequency Drive unit cost is high, cause the Flying by wire system cost of top-drive drilling higher.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, a kind of strong adaptability is provided, controls accurately reliable, the switching Flying by wire system for top-drive device that cost is lower, this device is by pushing up the Frequency Drive unit that drives and rotating disk shares, thus save the Frequency Drive unit of rotating disk, reach the object reducing cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of switching Flying by wire system for top-drive device, it comprises driller's control box, top is driven, derrick saddle, switching cabinet is driven on top, inversion out-put supply, rig VFD room, travelling cable and cable performance loop, top is provided with sensor in driving, electromagnetic valve, junction box, direct driving motor and encoder, encoder is electrically connected with junction box, sensor, electromagnetic valve is electrically connected with junction box, derrick saddle is arranged on direct driving motor and top and drives on the circuit that switches between cabinet, travelling cable is arranged on the circuit between direct driving motor and derrick saddle, inversion out-put supply is arranged on top and drives on the circuit that switches between cabinet and rig VFD room, driller's control box and top are driven and are switched cabinet and be electrically connected.
The utility model has the following advantages: the utility model can realize numerical control variable frequency, totally digitilized operation control system and zero rotating speed and export the functions such as torque capacity; VFD room CPU can be made to realize the digital transmission of control signal, diagnostic message, relevant parameter with switching cabinet and driller's control cabinet by PROFIBUS field bus-DP technology; can monitor in real time whole system; the fault occurred is indicated in time, reports to the police and protected, and system has the anxious defencive function such as to stop of peak torque setting, loss protecting and transmission system.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the switching Flying by wire system for top-drive device.
In figure, 1-driller's control box, 2-sensor, 3-electromagnetic valve, 4-junction box, 5-direct driving motor, 6-encoder, 7-drives on top, 8-derrick saddle, and 9-drives switching cabinet, 10-inversion out-put supply in top, 11-rig VFD room, 12-600VAC, 13-400VAC, 14-PROFIBUS-DP, 15-move about cable.
