Abstract
The utility model relates to a head sheave type long stroke oil pumping machine used for pumping crude oil on the ground in an oil field. The utility model is characterized in that a head sheave used for bearing load is positioned at one side of the top of a machine frame; the other side is connected with a driving reverse wheel through a central shaft of the head sheave; the driving reverse wheel is connected with a short connecting rod at the lower part through a flexible driving member; a power part adopts an adjustable speed motor which is positioned at one side of a base of the machine frame and is connected with an open type speed reducing mechanism driven by a belt and a chain; symmetrical cranks which mutually form 180 DEG are arranged on a power output wheel shaft of the speed reducing mechanism; the cranks are connected with the short connecting rod. The head sheave type long stroke oil pumping machine changes the original reversing mode that a guide rod drives the reversing operation into a reversing mode that the flexibility drives the reversing operation, which simplifies the driving structure and leads moving members to be reduced. An enclosed type reducing gear box is structurally cancelled, which leads the weight of the complete machine to be reduced, and simultaneously, leads the manufacturing difficulty degree and the manufacturing cost to be lowered. The utility model has the advantages of simple structure of the complete machine, light weight, few wearing parts, energy saving, material saving, convenient installation and maintenance, etc.
Description
Technical field:
The utility model belongs to the mechanical oil recovery equip ment technical field, is a kind of head sheave long stroke pumping unit that is used for ground, oil field pumping crude oil.
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 and are dropped into the oil field in succession and use, 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,, good balance effect energy-conservation, easily realize characteristics such as long stroke with it, progressively enter the oilfield exploitation industry, and in oil production equipment as have development potentiality and popularizing application prospect wide new architecture, this machine 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 these facility have 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 provides a kind of head sheave long stroke pumping unit that adopts soft drive, thereby makes its structure more simple, and can reduce moving link, alleviates complete machine weight, is convenient to maintenance management.
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, head sheave, balance weight, crank-link mechanism, reducing gear, motor, braking mechanism, its main feature is: the head sheave that is used for bearing load is positioned at a side of frame top, opposite side is connected with the driving reverse wheel by the head sheave central axis, drives reverse wheel and is connected with the short connecting rod of bottom by flexible drive parts; Buncher is adopted in power section, is positioned at gantry base one side, and is connected with belt, chaindriven open type reducing gear, and 180 ° the crank each other of symmetry is housed on the power output wheel axle of reducing gear, and crank is connected with short connecting rod.
The head sheave long stroke pumping unit of making according to such scheme, original guide rod is driven commutation change the soft drive commutation into, and on moving link, cancelled former head sheave oil pumper the roller bearing travel prolongation mechanism, guide guide rail and idler wheel mechanism into, structurally given up enclosed gear reduction box, simplified the structure of head sheave type oil pumper thus more, the weight of complete machine is significantly reduced, also reduced manufacture difficulty and manufacturing cost simultaneously.Compared with prior art, these facility have complete machine structure simple, in light weight, few easy workout part, advantages such as 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:
Referring to Fig. 1 Fig. 2, head sheave long stroke pumping unit of the present utility model, be by base 1, frame 2, sucker rod 3, head sheave 4, drive reverse wheel 5, flexible drive parts 6, balance weight 7, short connecting rod 8, crank 9, reducing gear, motor 12, braking mechanism 13 are formed, wherein, 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 7.Opposite side is connected with by the head sheave central axis and drives reverse wheel 5, drive being connected between reverse wheel 5 and the flexible drive parts 6, can adopt chain drive structure, also can directly adopt the rope sheave drive mechanism, wherein, chain drive is to constitute (as shown in the figure) by sprocket wheel and chain; The rope sheave transmission is formed (not shown) by rope sheave and wire rope, for guaranteeing the reliability of work, prevents the fracture of wire rope, puts the wire rope that has more than at least three in arrangement on the rope sheave, can prolong the application life of wire rope effectively.For guaranteeing to drive the center to center distance of reverse wheel 5 and short connecting rod 8, between flexible connecting member 6 and short connecting rod 8, be provided with center to center distance wire clips adjustment means 14 simultaneously.Buncher 12 is adopted in the power section of this machine, be positioned at gantry base 1 one sides, and be connected with the open type reducing gear of belt transmission and chaindriven double reduction, label 10,11 among the figure is respectively sprocket wheel and the belt pulley in the reducing gear, adopt the open type slowing-down 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.180 ° the crank 9 each other of symmetry is housed on the power output wheel axle of reducing gear, and crank 9 is connected with short connecting rod 8.Oil pumper braking mechanism 13 still adopts known technology.This machine operating principle is: utilize buncher 12 directly to drive crank 9, short connecting rod 8 behind double reduction, and by 5 rotations of flexible drive parts 6 drive driving reverse wheels, load head sheave 4 is also done the oscillating motion of simple harmonic quantity formula thereupon synchronously, thereby drive sucker rod 3 and balance weight 7 pump.
