Description
Technical field
The utility model belongs to oil pumper mechanical field, relates in particular to a kind of clip system that can prevent holddown or disconnected bar or belt fracture.
Background technology
Oil pumper is when pumping, and be connected with sucker rod in the belt bottom of belt pulley by polished rod eye, sucker rod carries out oil pumping operation under the effect of oil well pump.In normal operation situation, oil pump plunger piston has a stroke, namely goes up to point 14, stage casing 16 to being a stroke down to the distance between point 17.Once oil pump plunger piston is stuck in pumpingh well or rod broken, and control system also makes oil well pump work at driving actuating unit, can shorten the application life of oil well pump like this, cause driving mechanism to damage what is more, even can cause serious accident.
Utility model content
The purpose of this utility model is to overcome the clip system that above-mentioned deficiency provides a kind of anti-rod broken, holddown, belt fracture, and this device when oil well pump holddown or sucker rod break bar, can make the power-off of whole mechanism, can not cause a serious accident.
For achieving the above object, the utility model is by the following technical solutions:
A kind of anti-rod broken, holddown, the clip system of belt fracture, comprise the sucker rod be arranged on rope rotator, the rope rotator of sucker rod both sides is provided with pull bar, pull bar is connected with belt by belt fastener, rope rotator is provided with the through hole passed for sucker rod, the aperture of through hole is greater than the external diameter of sucker rod, sucker rod is provided with clip, the top of through hole is provided with the groove matched with clip, the rope rotator of clip side is also provided with support, on the horizontal level between belt fastener and clip of the top of support, cradle top side is provided with clip sensor, clip sensor is connected with controller.
The clip system of above-mentioned anti-rod broken, holddown, belt fracture, the pull bar of rope rotator bottom is provided with deck, be matched in clearance between pull bar and rope rotator, cradle top opposite side is provided with belt fastener proximity switch, belt fastener proximity switch is connected with controller.
The clip system of above-mentioned anti-rod broken, holddown, belt fracture, described clip comprises fixed cover and is located at card cap on sucker rod, and the area of the upper end section of card cap is greater than card cap lower end section area, and the shape on through hole top is consistent with card cap lower surface shape.
The clip system of above-mentioned anti-rod broken, holddown, belt fracture, described card cap is made up of the large rectangle nut on top and the little microscler nut of bottom.
The clip system of above-mentioned anti-rod broken, holddown, belt fracture, described card cap is made up of the large Rotary-table on top and the little Rotary-table of bottom.
The clip system of above-mentioned anti-rod broken, holddown, belt fracture, described card cap is made up of the large Rotary-table on top and the small cone body of bottom.
Adopt technique scheme, the utility model has following advantage: when the reciprocal regular event of load-bearing, clip can move down with rope rotator under the effect of oil well pump, and at this moment clip can not touch clip sensor, controller regular event.When holddown, oil pump plunger piston snaps into putting, and belt polished rod eye is downward, clip is motionless, and such clip touches clip sensor, and clip sensor is connected with controller, pass in controller by the information of holddown like this, controller controls whole dynamical system power-off.Or when belt fracture, belt buckle and pull bar move down, and polished rod eye is motionless, then belt buckle touches belt fastener proximity switch, and belt fastener proximity switch is connected with controller, thus controller is made to control whole dynamical system power-off.Protect oil well pump, the generation of major accident avoided by the actuating unit simultaneously also protecting complete machine.The utility model structure is simple, easy to operate, the serious accident caused after can preventing holddown or rod broken.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The anti-rod broken of one as shown in Figure 1, holddown, the clip system of belt fracture, comprise the sucker rod 6 be arranged on rope rotator 4, the rope rotator of sucker rod 6 both sides is provided with pull bar 3, pull bar is connected with belt 1 by belt fastener 2, rope rotator is provided with the through hole 9 passed for sucker rod, the aperture of through hole 9 is greater than the external diameter of sucker rod, sucker rod is provided with clip, the top of through hole 9 is provided with the groove matched with clip, the rope rotator of clip side is also provided with support 13, on the horizontal level between belt fastener 2 and clip of the top of support 13, cradle top 11 side is provided with clip sensor 10, clip sensor 10 is connected with controller. in normal operation situation, oil pump plunger piston has a stroke, namely go up to putting 14, stage casing 16 is to being a stroke down to the distance between point 17.Clip can not touch clip sensor.When oil well pump holddown, oil pump plunger piston 15 is stuck in putting 14, and belt polished rod eye is downward, clip is motionless, and such clip touches clip sensor, and clip sensor is connected with controller, pass in controller by the information of holddown like this, controller controls whole dynamical system power-off.。
When belt fracture, to be on the safe side, the pull bar of rope rotator bottom is provided with deck 5, is matched in clearance between pull bar and rope rotator, and cradle top 11 opposite side is provided with belt fastener proximity switch 12, belt fastener proximity switch 12 is connected with controller, once belt fracture, belt fastener moves down, and polished rod eye is motionless, then belt fastener touches belt fastener proximity switch, start-up connector power-off.
The concrete structure of the utility model clip is as follows: described clip comprises fixed cover and is located at card cap on sucker rod, and the area of the upper end section 7 of card cap is greater than end section 8 area under card cap, and the shape on through hole top is consistent with card cap lower surface shape.
