Abstract
The utility model relates to an oil pumping unit crank pin unscrewing alarm device, which is used for the trouble alarm of a beam oil pumping unit, in particular to an unscrewing alarm of the oil pumping unit crank pin. The oil pumping unit crank pin unscrewing alarm device comprises the unscrewing alarm device and a magnet steel. The utility model is characterized in that the unscrewing alarm device is fixed on the fixing nut of the oil pumping unit crank pin, and a dry spring pipe, a signal alarming circuit, and a signal wireless transmitting circuit are arranged in the unscrewing alarm device; the magnet steel is stuck on the outer surface of the oil pumping unit crank, and the distance between the fixed position of the magnet steel and the fixing nut is 20 to 70 mm. The utility model has the advantages that the oil pumping unit crank pin unscrewing alarm device is arranged on the oil pumping unit crank, when the fixing nut of the crank pin is unscrewed and loosened, an alarm signal can be sent out, thus notifying the managers to take measures and the maintainers to overhaul the fixing nut, and preventing the accidents from occurring.
Description
Technical field
The utility model relates to a kind of beam-pumping unit accident warning device in oil field, and particularly a kind of Crank Pin on Pumping Units is moved back the button warning device.
Background technology
At present, recovering the oil with the oil pumper majority in the oil field is walking-beam pumping unit, adopts toggle to transmit moment of torsion and commutation.Crank pin is the important coupling components on the connecting rod.The beam-pumping unit crank pin is subjected to the influence of alternate load, the stressing conditions complexity.Cause crank pin loosening, very easily get loose, cause the oil pumper overthrow accident to take place often, had a strong impact on the ordinary production in oil field, caused enormous economic loss to the oil field.The locking way of existing crank pin adopts the clamp nut trough of belt to add cotter; Or adopt identical rotation direction set nut to lock.Above-mentioned locking measure, unreliable, can not anticreep.Because of getting loose, crank pin cause stopping production accident rate every year about 5/1000ths.The technician designs more loosing Prevention Technology scheme.As Chinese patent notification number 2787874, title: anti-loosing type crank pin assembly, adopt thrust bearing, thrust bearing is installed on the crank pin and with bearing seat and is connected; One end of crank pin has gland, and tapered sleeve is installed on the crank pin; Set nut is by pad locking crank pin tapered sleeve; Thrust washer and retainer nut are positioned at the crank pin end.Can prevent crank pin to get loose, if but get loose still and can cause damage.
The utility model content
The purpose of this utility model is: provide a kind of Crank Pin on Pumping Units to move back the button warning device, moving back button, become flexible in Crank Pin on Pumping Units is to send alerting signal, notifies managerial personnel to take measures, and maintenance personal's maintenance is eliminated accident before not taking place.Stop the loss that crank pin becomes flexible, moves back cingulum,
The technical solution adopted in the utility model is: Crank Pin on Pumping Units is moved back the button warning device, comprise and move back button alarm and magnet steel, it is characterized in that moving back the button alarm and be fixed on the hold-down nut of Crank Pin on Pumping Units, moving back in the button alarm has tongue tube, signal alarm circuit and signal wireless radiating circuit.Tongue tube also claims magnetic reed switch, as magnet proximity switch.Be fixed with magnet steel at the oil pumping machine crank outside surface.When nut location changes, rotate, move back button, be with move back the button alarm rotate together.Rotate to an angle moving back the button alarm, when being fixed on magnet steel on the crank, move back reed switch conduction in the button alarm, produce the adhesive pulse signal, outwards send signal by wireless mode, be transmitted into and be installed in the single well-controlled device, report to the police to Central Control Room after treatment.
Described at the fixing magnet steel of oil pumping machine crank outside surface, its fixing means is bonding.
The fixed position of magnet steel and the distance of hold-down nut are between the 20-70 millimeter.
Described tongue tube and magnet steel effect produce pulse signal principle and signal alarm circuit, signal wireless radiating circuit, and the single well-controlled device, to technology such as Central Control Room warnings, be mature technology, be not described in detail.
The beneficial effects of the utility model: Crank Pin on Pumping Units is moved back the button warning device be installed on the oil pumping machine crank, the nut of crank pin moves back button, when becoming flexible, can send alerting signal, notifies managerial personnel to take measures, maintenance personal's maintenance, and the accident of stopping takes place.
Description of drawings
Fig. 1 be the utility model Crank Pin on Pumping Units move back the button warning device move back button alarm and magnet steel fixed position synoptic diagram.The arrow direction is the direction that nut 4 moves back rotation when detaining.
Among the figure, 1. crank, 2. counterbalance weight, 3. crank pin, 4. nut, 5. magnet steel 6. moves back the button alarm.
Embodiment
Embodiment 1: consult Fig. 1.The utility model Crank Pin on Pumping Units is moved back the button warning device, and moving back in the button alarm (6) has tongue tube as magnet proximity switch, also comprises signal alarm circuit and signal wireless radiating circuit.At Central Control Room reception, warning device are arranged.Magnet steel (5) is the column strong magnet of 10 millimeters of diameters.Move back and detain the outside that alarm (6) is fixed on the hold-down nut (4) of Crank Pin on Pumping Units (3).At the outside surface of (4) 50 millimeters on oil pumping machine crank (1) the fixed distance nut magnet steel (5) that is adhesively fixed.When hold-down nut (4) moves back mouthful a rotation half-turn, move back button alarm (6) and rotate to magnet steel (5) approachingly together, tongue tube is connected as magnet proximity switch and is moved back button alarm (6) circuit, sends alerting signal.
Claims (3)
1. a Crank Pin on Pumping Units is moved back the button warning device, comprise and move back button alarm (6) and magnet steel (5), it is characterized in that: move back button alarm (6) and be fixed on the hold-down nut (4) of Crank Pin on Pumping Units (3), moving back in the button alarm (6) has tongue tube, signal alarm circuit and signal wireless radiating circuit; Outside surface at oil pumping machine crank (1) is fixed with magnet steel (5).
2. Crank Pin on Pumping Units according to claim 1 is moved back the button warning device, it is characterized in that: described outside surface at oil pumping machine crank (1) is magnet steel (5) fixedly, and its fixing means is bonding.
3. Crank Pin on Pumping Units according to claim 1 and 2 is moved back the button warning device, it is characterized in that: the distance of the fixed position of magnet steel (5) and hold-down nut (4) is between the 20-70 millimeter.
