Abstract
The utility model relates to an anti-falling device used on a polished rod of a pumping unit of a pumping well, in particular to an anti-falling device for a polished rod of a pumping unit. The anti-falling device for the polished rod of the pumping unit comprises a hanging device and an anti-disengaging device. The hanging device is hung on a beam hanger of the pumping unit, a baffle is fixed to the lower end of the hanging device in a penetrating through mode through screws and nuts, and the polished rod of the pumping unit penetrates through the beam hanger of the pumping unit and the baffle. The anti-disengaging device is fixed to the upper end of the beam hanger of the pumping unit and the portion, at the lower end of the baffle, of the polished rod of the pumping unit. The anti-falling device for the polished rod of the pumping unit has the advantages that oil and gas leakage, oil well shut-off and environment pollution caused by breakage and falling of the polished rod of the pumping unit are reduced, ton oil cost is reduced, precision management is promoted, and solution of the crucial problem about environment cleaning is guaranteed; in actual oil well operation, the anti-falling device is developed and tried out on a heavy load pumping unit, normal operation of the pumping unit can still be guaranteed even after the polished rod fractures in the position of a load clamp, and the effect is good.
Description
Technical field
The utility model relate on the oil-extractor polish-rod of pumpingh well, use prevented dropping device, particularly oil-extractor polish-rod anti-drop device.
Background technology
The 12 type oil pumper mechanical oil recoverys that adopt when current each oil field is used for thickened oil recovery more, during due to thickened oil recovery, the load of oil pumper is large, and at load clamp place, often there is phenomenon of rupture in oil-extractor polish-rod, and after polished rod fracture, this oil well must stop production, and can reduce production output; Oil pumper is losing after load, and up-downgoing imbalance can cause the damage of reduction box and motor; After oil-extractor polish-rod fracture, can fall into after well in addition, if well head is not controlled, the crude oil in producing well and in whole oil extraction system can be emerged from packing box, causes well site pollution in wide area.Therefore, polished rod breakage problem has seriously restricted the development of Haiwaihe oilfield.
Summary of the invention
Goal of the invention of the present utility model is, a kind of oil-extractor polish-rod anti-drop device is provided, this oil-extractor polish-rod anti-drop device is suspended on the polished rod eye of oil pumper, in the situation that oil-extractor polish-rod comes off, oil-extractor polish-rod be can fix timely, the device damage and the crude oil pollution that because of oil-extractor polish-rod landing, cause prevented.
The utility model is achieved in that a kind of oil-extractor polish-rod anti-drop device to achieve these goals, comprises suspension arrangement and Anti-release clamp device; Suspension arrangement is suspended on beam hanger for pumping machine, and suspension arrangement lower end connected screw and nut perforation and is fixed with baffle plate, and oil-extractor polish-rod is through beam hanger for pumping machine and baffle plate; On the oil-extractor polish-rod of the fixing beam hanger for pumping machine upper end of Anti-release clamp device and baffle plate lower end.
Under suspension arrangement be Π type, described Π type suspension arrangement be a pair of more than.
Described baffle plate is made as anti-falling steel plate.
Described Π type suspension arrangement is made as Π shaped steel cover.
The described Anti-release clamp device side of being made as card, side fastens on oil-extractor polish-rod, drives under external force oil-extractor polish-rod to pump.
The utility model oil-extractor polish-rod anti-drop device, when operation, Π shaped steel cover hangs on beam hanger for pumping machine, and Π shaped steel cover bottom adopts bolt perforation to be connected with anti-falling steel plate.When oil pumper is worked under normal condition, oil-extractor polish-rod anti-drop device is inoperative, when polished rod fractures at load clamp place, the oil-extractor polish-rod fractureing under sentencing can not come off under the effect of anti-falling steel plate, Π shaped steel cover and side's card, side's card drops on the load of oil-extractor polish-rod on polished rod eye again, square clamp now has become load clamp, by the moving oil-extractor polish-rod of square cassette tape, pumps.Oil pumper can also carry out the exploitation work of viscous crude, and just this oil pumper is in treating service mode.
The utility model oil-extractor polish-rod anti-drop device has reduced disconnected de-oil and gas leakage, the oil well causing of pumping well polish rod and has stopped well and environment pollution, reduces production cost per tone oil, promotes precision management, guarantees the difficult problem of assaulting fortified position of clean environment.In actual oil field operation, on the large oil pumper of load, research and develop trial edition utility model, at polished rod, after the fracture of load clamp place, still can guarantee that oil pumper runs well, respond well.
Oil-extractor polish-rod anti-drop device can prevent in the situation that polished rod fractures that polished rod from falling into well, avoids, because the fracture motor that causes and reduction box of polished rod damages, guaranteeing oil pumper continuous operation.It is convenient to repair, and without operation, just polished rod can be returned to normal position, has effectively stopped the formation damage that light rod-broken causes.
The utility model oil-extractor polish-rod anti-drop device cost of manufacture is low, easy and simple to handle, can promote the use of at the large rod-pumped well of load, effectively solves the easily broken de-hard nut to crack of heavy oil block polished rod.
Accompanying drawing explanation
Fig. 1 is the structural representation of oil-extractor polish-rod anti-drop device.
Fig. 2 is the lateral view of Fig. 1.
Π shaped steel cover 1 in figure, side's card 2, anti-falling steel plate 3, beam hanger for pumping machine 4, oil-extractor polish-rod 5.
The specific embodiment
As shown in Fig. 1 Fig. 2
Below in conjunction with accompanying drawing, the utility model is described further: a kind of oil-extractor polish-rod anti-drop device, comprises Π type suspension arrangement and Anti-release clamp device; The type of Π shown in figure suspension arrangement is made as a pair of Π shaped steel cover 1, and the lower end of a pair of Π type suspension arrangement is connected and is fixed with baffle plate by screw and nut, and shown in figure, described baffle plate is made as anti-falling steel plate 3.The device of Anti-release clamp shown in the figure side of being made as card 2.
The shaped steel of Π shown in figure cover 1 is suspended on beam hanger for pumping machine, and oil-extractor polish-rod 5 is used to through beam hanger for pumping machine 4 and anti-falling steel plate 3; Side's card 2 is fixed on the oil-extractor polish-rod 5 of beam hanger for pumping machine 4 upper ends and anti-falling steel plate 3 lower ends.Side's card 2 can drive oil-extractor polish-rod 5 to pump under external force.
The utility model oil-extractor polish-rod anti-drop device; to utilize suspension arrangement and Anti-release clamp device that the oil-extractor polish-rod of fracture is fixed on beam hanger for pumping machine; under the effect of beam hanger for pumping machine and Anti-release clamp device, oil-extractor polish-rod is still normally worked; certainly this is optimum implementation of the present invention; those skilled in the art, do not change under the mode of anti-drop device; can also to the present invention make further modification and retouching all can reach the effect that the present invention makes, these all belong to protection scope of the present invention.
