The utility model discloses simplified the structure of head sheave formula beam-pumping unit, made the complete machine weight of beam-pumping unit alleviate greatly, also reduced the manufacturing degree of difficulty and manufacturing cost simultaneously. Compared with the prior art: the machine has the advantages of simple structure, light weight of the whole machine, energy and material conservation, convenient installation and maintenance and the like.
Description
Technical field:
The utility model belongs to the mechanical oil recovery equip ment technical field, is that the head sheave long stroke pumping unit that draws crude oil is adopted on a kind of ground, oil field that is used for
Background technology:
In technique known, long stroke, low jig frequency, big discharge capacity, heavy duty oil pumper are the developing direction of domestic and international mechanical oil recovery equip ment, since the eighties in 20th century, various blue elephants are made in succession and are come into operation, and indicate that the development of oil pumper technology is greatly improved.Because oil pumper is a kind of special equipment of working continuously in the open air, therefore, the oil field to the requirement of oil pumper be simple, sturdy, reliable, be convenient to maintenance, be convenient to management, be convenient to install.In existing technology, disclosed a kind of head sheave type does not have the walking beam stroke increased oil pumping machine, energy-conservation, in light weight with it, easily realize characteristics such as long stroke, progressively enter the oilfield exploitation industry, and conduct has development potentiality and the wide new architecture of popularizing application prospect in oil production equipment, its structure is to drive the roller bearing travel prolongation mechanism by crank-link mechanism to promote the head sheave swing, and pumps by the wire rope drive sucker rod that is wrapped on the head sheave, realizes the long stroke operation.But when having significant advantage, also some problem demanding prompt solutions of existence in various degree, as: because the mode that adopts drag link to drive, make its structure that increases the journey part comparatively complicated, moving link is many, the field maintenance difficulty, structural member and driving mechanism are stressed big, and manufacturing and operational administrative difficulty are big.
The utility model content:
The purpose of this utility model provide a kind of structure more simple, can reduce moving link, be convenient to the head sheave long stroke pumping unit that the single connecting rod of maintenance management drives
Realize that the technical scheme that the purpose of this utility model is taked is the improvement of carrying out on the basis of original head sheave type oil pumper, these facility have base, frame, balance weight, head sheave, crank-link mechanism, motor, braking mechanism, its main feature is: the head sheave that is used for bearing load is positioned at a side of frame top, and opposite side is connected with single connecting rod by the head sheave main shaft and drives linked component; Buncher is adopted in power section, is positioned at gantry base one side, and is connected with belt, chaindriven open type reducing gear, and the power output wheel axle in the reducing gear drives linked component with single connecting rod and is connected.This machine, and drives single connecting rod and drives the linked component motion through the reducing gear outputting power by buncher, drives the head sheave swing simultaneously, drives the sucker rod that hangs on the head sheave, the reciprocating motion that balance weight realizes oil pumper with this.
Described single connecting rod drives linked component and is made up of single rocking bar, single connecting rod, single crank, wherein, single rocking bar is installed in a side of head sheave central axis, have the guide groove that is used to increase stroke on it, be connected with single connecting rod by a slide mass that can move in guide groove in the guide groove, the other end of single connecting rod is connected with single crank on the power output shaft that is installed in reducing gear.
The head sheave long stroke pumping unit of making according to such scheme, in structure, cancelled the moving link of traditional double link, double-crank, double rocking lever, but adopted single connecting rod type of drive, therefore, there is not the problem of price scissors in the movement parts, do not have large-scale workpiece yet, and given up enclosed gear reduction box, thereby simplified the structure of head sheave type oil pumper, the complete machine weight of oil pumper is alleviated greatly, also reduced manufacture difficulty and manufacturing cost simultaneously.Compared with prior art: these facility have simple in structure, advantages such as complete machine is in light weight, energy-conservation province material, installation and maintenance convenience.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment:
In Fig. 1, Fig. 2, each label is respectively: base 1, frame 2, sucker rod 3, head sheave 4, head sheave central axis 5, rocking bar 6, slide mass 7, balance weight 8, single connecting rod 9, single crank 11, reducing gear, motor 13, braking mechanism 14.
Referring to Fig. 1 Fig. 2, head sheave long stroke pumping unit of the present utility model, adopt single connecting rod drives structure, its structure is: in pumping unit shelf 2 tops one side, the head sheave 4 that is used for bearing load is installed, polished rod eye 4-1 is housed on the head sheave 4 and is used to hang the lifting rope 4-2 of sucker rod 3 and balance weight 8, opposite side is connected with single connecting rod by head sheave central axis 5 and drives linked component, this assembly is by single rocking bar 6, single connecting rod 9, single crank 11 is formed, wherein, single rocking bar 6 is installed in a side of head sheave central axis 5, have the guide groove 6-1 that is used to increase stroke on it, be installed in the guide groove by one among the guide groove 6-1 and can be connected with single connecting rod 9 along the slide mass 7 that guide groove moves, the other end of single connecting rod 9 is connected with single crank 11 on the power output shaft that is installed in reducing gear.Buncher 13 is adopted in power section, be positioned at a side of gantry base 1, and be connected with the open type reducing gear of the double reduction that belt transmission and chain drive constitutes, label 10,12 among the figure is respectively sprocket wheel and the belt pulley in the reducing gear, adopt this kind structure, be to be convenient to field maintenance, replacing on the one hand, can alleviate complete machine weight on the other hand, reduce manufacturing cost and maintenance cost.For satisfying the needs of field work, the guard shield (not shown) that is easy to dismantle can be set in the reducing gear outside.Oil pumper braking mechanism 14 still adopts known technology, is not giving unnecessary details herein.The single connecting rod driving linked component of this machine utilization setting and the mode of the direct hanging balancing of head sheave realize the swabbing operation of long stroke, therefore, there is not the price scissors problem in moving link, and the fine setting of stroke can be carried out at any time according to the needs that hole condition changes in the position of crank-pin, works under good operating mode to guarantee oil pumper.The course of work of this machine is: pass through belt, chaindriven reducing gear outputting power by motor 13, drive single connecting rod and drive the linked component motion, single connecting rod 9 is under the effect of crank 11, driving single rocking bar 6 swings repeatedly, pass through the effect of the slide mass 7 in the guide groove 6-1 again, and utilize the angle of head sheave 4 swings and the multiple relation of single rocking bar 6 angles of oscillation to reach the purpose that increases journey.The lifting rope 4-2 that is used to hang sucker rod 3 and balance weight 8 is wrapped in head sheave, and direction is opposite, when head sheave 4 is swung repeatedly, drives sucker rod 3 and balance weight 8 and pumps, thereby reach the purpose of pumping crude oil from oil well.
