Abstract
A device for determining and displaying the rotating speed of a main motor of an armature workover rig is applied to determine the rotating speed of the main motor of the armature workover rig in an oil field. An annular sleeve is fixed on the output shaft of the motor, and 31 raised electromagnetic induction points are fixed on the periphery of the annular sleeve and evenly distributed on the annular sleeve; electromagnetic induction heads are opposite to the electromagnetic induction points and are fixed on a workover rig vehicle beside the output shaft of the motor. The electromagnetic induction heads are connected with tachometers by a lead, and the tachometers are respectively arranged on a master console, a cab and a driller console. The effects of the utility model are as follows: the rotating speed of the main motor is independently measured and is not influenced by circuit signal factors. 31 raised electromagnetic induction points are fixed on the annular sleeve, thus ensuring the detection accuracy on the rotating speed of the main motor. A master control system which is used as a rotating speed signal of a secondary motor has a function of correcting the signal of the main motor. The instrument display is convenient to read and watch, thus realizing real-time monitoring on the rotating speed of the main motor.
Description
Technical field
The utility model relates to the oil field electricity and drives the main motor speed mensuration of workover rig and the device that shows.
Background technology
At present, the main motor speed that electricity drives workover rig is the signal that feeds back by Hall Plate, judges the rotating speed of main motor, and signal is stored in the master control system chip by the signal of telecommunication.The signal of Hall Plate feedback is the foundation as the main motor speed of unique judgement.But the signal of Hall Plate feedback can not be realized conversion to driller's station, bridge instrumentation and show.Have specifically following some problem: 1. the accuracy of signal can not guarantee; 2. signal is affected by circuit; In case 3. the wrong way that does not have judgement appears in signal; 4. be inconvenient to read and watch, can not realize monitoring constantly; 5. the suspending weight in the construction and the rotating speed correlation of main motor do not have scientific basis; 6. be unfavorable for that electricity drives improving of workover rig.
The utility model content
The purpose of this utility model is: provide a kind of electricity to drive workover rig master motor speed and measure and display unit, provide electricity to drive workover rig master motor speed mensuration and demonstration.
The technical solution adopted in the utility model is: electricity drives workover rig master motor speed and measures and display unit, mainly formed by motor output shaft, annular cover, electromagnetic induction point, electromagnetic induction head and revolution counter, it is characterized in that: the annular cover that is fixed with an annular at motor output shaft, be fixed with the electromagnetic induction point of 31 protrusions at the outer wall of annular cover, the electromagnetic induction point is evenly distributed on the annular cover cylindrical; The electromagnetic induction head is relative with electromagnetic induction point, and the electromagnetic induction head is fixed on the other workover rig car body of motor output shaft.The electromagnetic induction head is connected with revolution counter by lead, and revolution counter is installed in respectively on master station, driver's cabin and the driller station.
After the workover rig work, main motor begins to rotate, and drives annular cover and electromagnetic induction point and rotates.At 31 fixing electromagnetic induction points of annular cover excircle, during each electromagnetic induction point process electromagnetic induction head, the electromagnetic induction head is experienced an induced signal.The electromagnetic induction head whenever receives 31 signal instruction main motor shafts and revolves and turn around.
After the electromagnetic induction head is sensed signal, be transferred to respectively three revolution counters by lead, i.e. the revolution counter that the revolution counter that the revolution counter of master station installation, driver's cabin are installed and driller station are installed.Provide main motor speed to measure and demonstration to operating personnel respectively.And main motor speed signal is transferred in the signal storage chip of master control system.
The beneficial effects of the utility model: the utility model electricity drives workover rig master motor speed and measures and display device, and main motor speed independent measurement is not subjected to the influence of circuit signal factor.Annular puts establishes 31 electromagnetic induction points, guarantees to measure the accuracy of main motor speed.Master control system realizes that to main motor signal has the function of error correction as less important motor speed signal.The instrument demonstration is conveniently read and is watched, and realizes in real time to main motor speed monitoring.
