Abstract
The automatic stop protector for preventing the crank pin of pumping unit from dropping is used for automatic protection of the crank pin dropping prevention of pumping beam type pumping unit. Is characterized in that: a bolt with a hinged joint is fixed in the middle of the supporting plate. The swing bracket is connected with the hinged joint through a bolt. An adjusting bolt is arranged on the supporting plate and penetrates through an adjusting hole of the swing bracket. The adjusting bolt is sleeved with a spring. A supporting plate and a proximity switch are fixed on the upper part of the swing bracket. A steel plate detecting body is fixed to an end face of the crank pin. When the crank pin of the pumping unit is disengaged, the approach switch is triggered to switch on the control circuit, the power supply of the pumping unit is cut off, the motor of the pumping unit stops rotating, and the alarm gives out sound and light alarms. The effect is as follows: the accident of the crank pin coming off can be monitored, and the accident of the pumping unit turning over caused by the coming off of the crank pin of the pumping unit is effectively avoided. The control circuit is not associated with the motion part of the oil pumping unit, so that the operation safety and reliability of the oil pumping unit are improved.
Description
Technical field
The utility model relates to technical field of petroleum extraction, and particularly a kind of safety guard of beam pumping unit belongs to a kind of Crank Pin on Pumping Units anticreep automatic shutdown protection device.
Background technology
At present, the recoverable amount of China's oil pumper is more than 100,000, and annually also increases with 5000 speed.Basically all be beam pumping unit at the oil pumper that field of petroleum exploitation adopted at present, because oil pumper all is mounted in open-air unmanned, oil pumper 1 year 365 days nearly all was work in 24 hours, and was bearing very big load.Crank Pin on Pumping Units is the easiest oil pumper component that accident occurs, all have every year and deviate to cause oil pumper because of Crank Pin on Pumping Units and turn over the machine accident, in a single day Crank Pin on Pumping Units deviates from the damage that can cause oil pumper support, connecting rod, crossbeam, walking beam, axis, tailing axle, and direct losses are above 100,000 yuan/time.On the on-the-spot at present oil pumper that uses Crank Pin on Pumping Units anticreep protective device is not installed substantially.All be by manually patrolling, owing to be not easy to realize after crank-pin crown nut is loosening, and crank-pin crown nut loosening after, will cause oil pumper to turn over the machine accident in a short period of time, so just can cause present oil pumper to turn over the phenomenon that the machine accident is difficult to stop.
Existing crank-pin anticreep technology has three kinds, and a kind of is two connecting rods to be strained by force with pull bar at small end, reaches the purpose of crank-pin anticreep.The Crank Pin on Pumping Units anti-dropping device that is provided as patent CN2459465; this class device is mechanical anti-drop device; when Crank Pin on Pumping Units crown nut pine after this kind device hold two connecting rods and can prevent that crank-pin from deviating from; but it can not find that crank-pin is loosening; can not be at the autostop that breaks down, loosening crank-pin can produce wearing and tearing so that fracture in the long-term operation process.Also has a class oil pumping machine crank anti-drop device, the disconnected well device that stops automatically of the oil pumping machine crank pin anticreep that is provided such as patent publication No. CN2893139, the common trait of such technology is with detecting element such as travel switch or all kinds of contact is installed on two connecting rods, find what crank-pin became flexible outward when moving by connecting rod, because this device is installed in small end, could trigger travel switch after having only connecting rod and upright position to form certain included angle, and travel switch is by mechanical action, self also has certain operating distance, it is also inapplicable above the travel switch that operating distance is little is positioned on, might make switch motion because expand with heat and contract with cold, so this class is with the technology of travel switch as checkout gear, just can move when crank-pin is deviate from more than 1 centimetre, prolong the time of discovery accident, can make the crank-pin wearing and tearing.Switch that such device detects the connecting rod displacement is connected to switchbox by a cable that moves up and down with oil pumper, so there is potential safety hazard in this device because cable move up and down can endurance failure throughout the year, it is dangerous that electric leakage takes place easily.Also have a class to adopt the Crank Pin on Pumping Units anticreep warning device of wireless electron receiving system; as patent CN2541601; when deviating from, crank-pin can effectively send warning; but there is not automatic stop arrangement; and its emitter need be installed battery; in case dead battery oil pumper just lost protection; adopted the Low-voltage Electronic element in its receiving system circuit; receiving system also will install the transformation fairing additional in switchbox; because oil pumper can produce very big dash current in start-up course; electronic component is damaged, and this device circuit complexity, be unfavorable for field maintenance.
The utility model content
The purpose of this utility model is: a kind of Crank Pin on Pumping Units anticreep automatic shutdown protection device is provided, can be when Crank Pin on Pumping Units be loosening autostop and reporting to the police, prevent that Crank Pin on Pumping Units from deviating to cause oil pumper to turn over the machine accident.
The technical solution adopted in the utility model is: Crank Pin on Pumping Units anticreep automatic shutdown protection device; mainly by the steel plate detection bodies, near switch, regulate bolt, height adjustment screw, spring, gripper shoe, band articulated joint bolt and swinging mounting and form; it is characterized in that: vertical fixing has gripper shoe on the oil pumper operating desk, is fixed with band articulated joint bolt at the middle part of gripper shoe.The end of band articulated joint bolt adopts pivot pin to connect the lower end of swinging mounting.Be fixed with one on the top of gripper shoe and regulate bolt, regulate the adjustment hole that bolt passes the swinging mounting middle part, regulate the bolt end and be fixed with nut.On the adjusting bolt, be with spring, and spring is between swinging mounting and gripper shoe.The angle of inclination that bolt can be regulated swinging mounting is regulated in rotation.Adopt the height adjustment screw to be fixed with a supporting plate on the top of swinging mounting.On supporting plate, be fixed with one near switch.On the crank-pin end face of oil pumper, be fixed with the steel plate detection bodies.The steel plate detection bodies is with relative near switch.After the crank-pin of oil pumper was deviate from, steel plate detection bodies distance was more and more nearer near the distance of switch, triggered near the switch connection control circuit, cut off the oil pumper power supply, made the pumping-unit motor stall, and alarm sends sound, light is reported to the police.
Described is higher-order of oscillation type inductance approach switch near switch.The steel plate detection bodies is a square, and the length of side is 50mm.
In order to make the height of regulating supporting plate more accurate, a bar hole is arranged on swinging mounting, described height adjustment screw is the fixing supporting plate of bar hole by swinging mounting.The fixing supporting plate in described swinging mounting top is a L-square.
Described spring is a spiral compression spring.
The beneficial effects of the utility model: the utility model Crank Pin on Pumping Units anticreep automatic shutdown protection device, can monitor crank-pin and deviate from accident, the oil pumper of avoiding oil pumper to deviate to cause because of crank-pin effectively turns over the machine accident.Crank-pin is deviate from 2mm and just can in time be found and stopping alarm, detects sensitively, shortened oil pumper and operated with failure the time, and control circuit and oil pumper motion parts does not have relatedly, has improved oil pumper running safety and reliability.
