Background
The pumping unit is a machine-mining device widely applied in the current oil exploitation, the motor provides power, the high-speed rotary motion of the motor is converted into the low-speed rotary motion of a crank of the pumping unit through a speed reducer, the rotary motion is converted into the up-and-down reciprocating motion of a horse head of the pumping unit through a crank-connecting rod-walking beam mechanism, and a square clamp, a polished rod and a deep well pump are driven to work through a rope hanger. In order to monitor the working condition of the deep well pump, a load meter is arranged between the square clamp and the rope hanger, and a work diagram of the deep well pump is tested and transmitted in real time.
However, in actual conditions, the oil well production fluid changes at any time. Because of the reasons such as wax or oil thickness in the crude oil, cause the down resistance increase of deep-well pump, the polished rod eye descends the speed and will be greater than polished rod and descend the speed to hysteresis appears: the square clamp on the polished rod is separated from the polished rod eye, the load meter between the two is under the unstressed condition, when the mule head of the pumping unit ascends, the polished rod eye drives the load meter to move upwards, and then the polished rod eye can generate strong collision with the square clamp on the polished rod, and the load meter can be directly damaged by the collision. Because the occurrence of the hysteresis is unpredictable and the adjustment intervention needs time to be completed, the occurrence of the impact is difficult to avoid, the monitoring of the indicator diagram is influenced, the maintenance and replacement cost is high, and the time and the labor are consumed. Therefore, when the hysteresis occurs, how to intervene in time and protect the load meter from being damaged becomes a problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a defect that can in time intervene, prevent square calliper direct impact load appearance when polished rod lags behind with not enough to existing among the prior art, effective protection load appearance is not impaired beam-pumping unit load appearance crashproof protector.
Realize the utility model discloses a technical scheme that the purpose was taken is: the protector comprises a supporting plate, a rope hanger, a spring and a supporting rod, wherein the supporting plate is positioned above the rope hanger, the supporting rod is connected to the front end face and the rear end face of the supporting plate respectively, the other end of the supporting rod is connected with the front end face and the rear end face of the rope hanger in a clamping mode through symmetrically arranged sliding grooves, the spring is arranged above the sliding grooves, one end of the spring is fixed to the front end face and the rear end face of the rope hanger, and the other end of the spring is connected with the middle lower portion of the supporting rod.
Two clamping positions are arranged in the sliding groove and are respectively positioned at two ends of the sliding groove, the lower end of the sliding groove is a preparation position, the higher end of the sliding groove is a protection position, the protection position is an oval groove hole, and a pressing plate and a fixing bolt are arranged on one side of the hole body.
The angle of inclination of spout is 15.
And a buffer rubber pad is arranged on the lower end surface of the supporting plate.
The beam-pumping unit load appearance crashproof protector made according to above-mentioned scheme, when the polished rod lags appearing, branch gets into the protection position along the spout under the transverse action of spring, constitute a protective structure this moment between fagging, branch, the polished rod eye, not only can prevent square card direct impact load appearance, effective protection load appearance is not impaired, intervene in time and intervene in the polished rod lag and increased necessary cushion time in addition, the cushion rubber pad of terminal surface can play certain auxiliary protection effect when the unexpected abnormal conditions can not get into spout protection position appear in branch under the fagging. This beam-pumping unit load appearance crashproof protector can prevent that the load appearance from directly being strikeed, has reduced maintenance and replacement cost, has both reduced intensity of labour, has improved work efficiency again, has structural design rationally, and the practicality is strong, and is simple and convenient easy-to-use, advantage that the effect is obvious.

Detailed Description
Referring to fig. 1, 2, 3, 4, the utility model discloses a beam-pumping unit load appearance crashproof protector, this protector include fagging 2, polished rod eye 4, spring 10 and branch 3, and wherein, fagging 2 is located polished rod eye 4 top, and the lower terminal surface of fagging 2 is equipped with rubber cushion pad 8, and rubber cushion pad 8 can play certain buffer protection effect under the circumstances that crashproof protector became invalid. The front end face and the rear end face of the supporting plate 2 are respectively connected with a supporting rod 3, the other end of the supporting rod 3 is connected with sliding grooves 5 symmetrically formed in the front end face and the rear end face of the rope hanger 4 in a clamping mode, springs 10 are arranged above the sliding grooves 5, one end of each spring 10 is fixed on the front end face and the rear end face of the rope hanger 4, and the other end of each spring is connected with the middle lower portion of the supporting rod 3. The angle of inclination of the chute 5 is 15. Two screens are arranged in the sliding chute 5 and are respectively positioned at two ends of the sliding chute 5, the lower end of the sliding chute is a preparation position 5-4, the higher end of the sliding chute is a protection position 5-1, wherein the protection position 5-1 is an oval slotted hole, and one side of the hole body is provided with a pressure plate 5-3 and a fixing bolt 5-2.
When the device is used, the rope hanger 4 is connected with the plumbs 11 of two Mao Bian rollers 6, the supporting plate 2 is arranged between the square clamp 7 and the load meter 9, the two fixing bolts 5-2 and the pressing plate 5-3 on the sliding groove 5 are firstly detached, one end of the supporting rod 3 is clamped and connected in the protecting position 5-1, then the pressing plate 5-3 is installed, the two fixing bolts 5-2 are tightened, then one end of the supporting rod 3 is manually lifted out of the protecting position 5-1 to slide to the preparatory position 5-4 of the sliding groove 5, the position of the horse head is adjusted, the square clamp 7 presses the supporting plate 2 downwards, the other end of the supporting rod 3 is connected on the supporting plate 2, one end of the spring 10 is fixed on the rope hanger 4, the spring 10 is pulled open, the other end of the spring 10 is connected with the supporting rod 3, and at the moment, the supporting plate 2, the load meter 9 and the rope hanger 4 are tightly connected.
