Abstract
The utility model relates to a rigid rod type oil pumping machine. The rigid rod type oil pumping machine is characterized in that the rigid rod type oil pumping machine is hinged in a four-connecting rod mechanism using some special scales. The rigid rod type oil pumping machine is designed according to the feature that a longer straight line segment is arranged in a connecting rod curve on a special point on a connecting rod. Thus, a main connecting rod (7), an upper frame connecting rod (8), a lower frame connecting rod (6), and a machine frame (9) are arranged to form the four-connecting rod mechanism. The four-connecting rod mechanism is driven to move under the function of a crank (4) and an auxiliary connecting rod (5), and thereby, the upper end point of the main connecting rod does very approximate linear motion to drive an oil pumping rod to do up-down peciprocating motion.
Description
The utility model relates to a kind of oil production equipment-oil pumper that supplies the recovery of subterranean oil to use.
Oil pumper is the capital equipment of recover petroleum.The oil pumper overwhelming majority of carrying out oil producing operation at present in each oil field of China is a beam pumping unit, and these oil pumpers all are the rectilinear motions that the swing of walking beam is changed into sucker rod by the wire rope of walking around horse head." the rotating horsehead pitch increased type long stroke pumping unit " of No. 88202313.6 patent disclosures of Patent Office of the People's Republic of China, though horse head can relatively rotate around walking beam, but by swinging up and down of walking beam being changed into the rectilinear motion of sucker rod around the wire rope of horse head.There is following weak point in the oil pumper of this horse head formula: 1, horse head weight is big, and in load one side, the line load of oil pumper is strengthened; 2, wire rope repeated deformation has in the course of the work reduced its application life; 3, horse head is a special shape, makes that manufacturing is not too convenient.
Task of the present utility model provides a kind of rigidity rod beam-pumping unit, save the horse head of the heaviness of conventional pumping unit, utilize the quadric chain of some special yardstick, change the rotation of crank output the rectilinear motion of sucker rod into, make and the utlity model has that complete machine is in light weight, simple in structure, reliable operation, be convenient to the characteristics of making, installing and keeping in repair.
The utility model is to utilize in the kink four bar linkage of some special yardstick, has the characteristics of long straightway to design on the connecting rod in the coupler-point curve of certain particular point.Its design main points are to be provided with master connecting-rod (7) in the oil pumper structure, slave connecting rod (5), last side link (8), following side link (6).One end of last side link is connected with the top of frame (9), and the other end is connected with the centre of master connecting-rod, and an end of following side link is positioned on the frame, and the other end is connected with the lower extreme point of master connecting-rod, makes it to form a quadric chain.One end of slave connecting rod is connected with crank (4), and the other end is connected with master connecting-rod.During work, the rotation of crank drives parallel motion by slave connecting rod.In the process of motion, the upper extreme point of master connecting-rod is done very approximate straight reciprocating motion along vertical, also pumps thereby drive sucker rod.
Rigidity rod beam-pumping unit described in the utility model is compared with existing oil pumper, and its advantage is to be bar type structure, simple shape, be easy to make, install and maintenance, hang the wire rope not distortion by bending in the course of the work of sucker rod, the life-span is longer, and service behaviour is safe and reliable.
Figure one is a structural scheme of mechanism of the present utility model.
Figure two is a perspective view of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described: in figure two, respectively there is a hinge seat at the top of support and middle part, be hinged with last side link and following side link respectively, the other end of last side link and the middle part of master connecting-rod are hinged, and the other end of following side link and the lower extreme point of master connecting-rod are hinged.Be provided with a bearing support on master connecting-rod, slave connecting rod is connected with bearing rod from the both sides of bearing respectively, promotes parallel motion with transferring power.Upper extreme point at master connecting-rod has an eyelet, and available bearing pin is at this fixing wire rope that hangs sucker rod.During oil pumper work, after the rotation of motor (1) is slowed down through Belt Transmission (2), reducer (3), make crank obtain required working speed, slowly running of crank drives the kink four bar linkage running by slave connecting rod, makes sucker rod produce and pumps.When the utility model was implemented, the yardstick of each bar, master connecting-rod may be selected to be 7.5 meters, and last side link is 3.75 meters, and following side link is 1.5 meters, and the distance on the frame between two free bearings can be 3 meters, also can suitably amplify in proportion or dwindle.
Claims (3)
1, a kind of by frame (9), reducer (3), the rigidity rod beam-pumping unit that crank (4) is formed, it is characterized in that in the oil pumper structure, being provided with master connecting-rod (7), last side link (8), following side link (6), an end of last side link is connected with frame, the other end is connected with the centre of master connecting-rod, one end of following side link is connected with frame, and the other end is connected with the lower end of master connecting-rod, makes it to form a quadric chain.
2, rigidity rod beam-pumping unit according to claim 1 is characterized in that being provided with slave connecting rod (5), and an end of slave connecting rod is connected with crank, and the other end is connected with master connecting-rod.
3, according to claim 1,2 described rigidity rod beam-pumping units, the length that it is characterized in that master connecting-rod is 7.5 meters, and last side link is 3.75 meters, and following side link is 1.5 meters, and the distance on the frame between two free bearings is 3 meters.
