Abstract
The utility model provides a beam -pumping unit with adjustable hydraulic pressure double -end, it includes the horse head body, support and base, the support sets up on the base, the support upper end is through axle bed and adjustable walking beam swing joint, adjustable walking beam both ends are equipped with a horse head body respectively, and the horse head body is connected with the sucker rod through the polished rod eye, the support both sides are fixed one pneumatic cylinder one end respectively, and the pneumatic cylinder other end is fixed on adjustable walking beam, the advancing oil pipe, go out the hydraulic pressure oil circuit that oil pipe incorporates the pneumatic cylinder into of pneumatic cylinder. The utility model discloses the suitability is strong, and the production prescription is high, the structure is light simple, easily makes, convenient transportation.
Description
Technical field
The utility model belongs to petroleum machinery apparatus field, particularly relates to a kind of dual-head hydraulic adjustable pumping unit.
Background technology
The extraction of domestic and international oil exploitation, crude oil adopts the driving of heavy gear, balancing weight crank connecting link, side or bilateral horse head body usually, and horse head body drives sucker rod that the crude oil of underground is extracted out.Although also have production Double head oil pumping in recent years, theory of mechanics or traditional mode.Walking beam is unadjustable, and actual vertical type oil well spacing can not be all equidistant, causes assembling difficulty.Gearbox and motor are connected by V belt to transmit power, and V belt makes with rubber, fragile, easily aging, easily lose, not easily held stationary transmits power, causes power consumption high like this, take material, can not ensure again normal effectively to work.
Utility model content
The purpose of this utility model is to overcome problems of the prior art, provides a kind of dual-head hydraulic adjustable pumping unit.
A kind of dual-head hydraulic adjustable pumping unit of the present utility model, it comprises horse head body, support and base, and described Bracket setting is on base; Pedestal upper end is flexibly connected with adjustable walking beam by axle bed; Described adjustable walking beam two ends are respectively equipped with a horse head body, and described horse head body is connected with sucker rod by polished rod eye; A hydraulic cylinder one end is fixed on described support both sides respectively, and the hydraulic cylinder other end is fixed on adjustable walking beam; The oil inlet pipe of described hydraulic cylinder, flowline are incorporated to the hydraulic circuit of hydraulic cylinder.
Described adjustable walking beam is closed by tooth buckle teeth by two pieces of walking beams.
The utility model compared with prior art has the following advantages:
1, the utility model applicability is strong, and production timeliness is high; Achieve and can regulate two horse head body uniformity according to the spacing of two mouthfuls of oil wells.
2, the utility model materials are few, efficiency is high; What adopt is that hydraulic power optimizes traditional pump connecting rod crank gearbox Belt Drive mode, reaches and saves material 80%, economize on electricity 30%.
3, the utility model portable construction is simple, is easy to manufacture, convenient transport.
4, the utility model is suitable for field installation, technical stable good, not easily breaks down.
Accompanying drawing explanation
Below in conjunction with accompanying drawing to the further detailed description of detailed description of the invention of the present utility model.
Fig. 1 is structural representation of the present utility model.
In figure: 1-adjustable walking beam 2-horse head body, 3-hydraulic cylinder, 4-support, 5-oil inlet pipe, 6-flowline, 7-base, 8-axle bed, 9-sucker rod.
Detailed description of the invention
As a kind of dual-head hydraulic adjustable pumping unit of Fig. 1, it comprises horse head body 2, support 4 and base 7, and support 4 is arranged on base 7; Support 4 upper end is flexibly connected with adjustable walking beam 1 by axle bed 8; Adjustable walking beam 1 two ends are respectively equipped with a horse head body 2, and horse head body 2 is connected with sucker rod 9 by polished rod eye; Hydraulic cylinder 3 one end is fixed on support 4 both sides respectively, and hydraulic cylinder 3 other end is fixed on adjustable walking beam 1; The oil inlet pipe 5 of hydraulic cylinder 3, flowline 6 are incorporated to the hydraulic circuit of hydraulic cylinder 3.Adjustable walking beam 1 is closed by tooth buckle teeth by two pieces of walking beams.
During oil recovery, be connected fuel feeding by the oil inlet pipe 5 of hydraulic circuit and hydraulic cylinder 3, flowline 6, according to the distance of two mouthfuls of oil wells, by the adjustment to adjustable walking beam 1 two pieces of walking beams, sucker rod 9 be positioned at directly over oil well.When left side hydraulic cylinder 3 moves upward, right side hydraulic cylinder 3 just moves downward, and centered by axle bed 8, a left side pushes away the right side and draws, and is the right easy motion pushing away Zola after conversion.
