Abstract
The utility model relates to a flexible drive wheel type long stroke pumping unit for swabbing crude oil in oilfield ground, which is mainly characterized in that: two sides of the wheel on the top of the frame is provided with driving change-wheels with coaxial synchronization rotation, the lower of the frame is provided with a low speed motor, the motor has double output shafts and is positioned on the base, the anterior motor is provided with a wheel shaft supporter, two ends of the wheel shaft is installed with an integration of crank pulleys, and are connected with the driving change-wheels through flexible ropes, the side of the frame is provided with a ladder and a pulley bracket for supporting and balancing the heavy wire rope. The utility model changes the flexible driving commutation for the guide-bar driving commutation of original machine type, which can simplify the transmission structure and reduce moving elements. for abandoning the original reduction gearbox, the weight of the whole machine is reduced, the manufacturing difficulty is decreased too, compared with the present technology, the utility model has the advantages of simple whole machine structure, light weight, low dynamic load, few fragile pieces, 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 soft drive 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 in succession and are come into operation, and indicate that the development of oil pumper technology has a very big raising.In the patented technology at home and abroad, 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, this machine is a kind of development potentiality that has, the new architecture that popularizing application prospect is wide, but when having significant advantage, also some problem demanding prompt solutions of existence in various degree, as: the structure that increases journey part and motion parts is comparatively complicated, moving link is many, field maintenance is difficult, structural member and driving mechanism are stressed big, and manufacturing and operational administrative difficulty are big.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, moving link is few, easy to maintenance, in light weight, dynamic load is little and the soft drive head sheave long stroke pumping unit being convenient to make.
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, balance weight, workbench, head sheave, sucker rod, frame, crank, braking mechanism, its main feature is: the head sheave both sides of frame top are provided with the driving reverse wheel of coaxial synchronous rotation, adopt securing member to connect therebetween, the bottom of frame is provided with slowspeed machine, motor is double output shaft and is positioned on the base, its front portion is provided with the wheel shaft supporting seat, the crank belt pulley of one is equipped with at the wheel shaft two ends, one end is connected with small belt pulley on the motor, the other end is connected with the driving reverse wheel of frame top by flexible rope, and the sidepiece of frame is provided with cat ladder and is used for a pulley yoke of stretching the balance weight wire rope.
The soft drive head sheave long stroke pumping unit of making according to such scheme drives commutation with the guide rod of former organic type and changes the soft drive commutation into, is the rope traction commutation, thereby simplified drive mechanism, and moving link is reduced.Advantages such as the utility model has structurally been given up reduction box, and the weight of its complete machine is significantly reduced, and has also reduced manufacture difficulty simultaneously, and compared with prior art, these facility have complete machine structure simple, and is in light weight, that dynamic load is little, few easy workout part, and installation and maintenance are convenient.
Utilize accompanying drawing to further describe embodiment of the present utility model below,
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 expressed as respectively: base 1, balance weight 2, cat ladder 3, pulley yoke 4, workbench 5, head sheave 6, driving reverse wheel 7, sucker rod 8, frame 9, crank 10, big belt pulley 11, motor 12, flexible rope 13,13a, pulley 4a, supporting seat 14.
Referring to Fig. 1, Fig. 2, top in pumping unit shelf 9, be provided with the head sheave 6 of coaxial synchronous rotation and drive reverse wheel 7, adopt securing member to connect as one between head sheave 6 and the driving reverse wheel 7, the base 1 of frame 9 bottoms is provided with slowspeed machine 12, motor 12 is a double output shaft, the transmission of power is carried out in one-level deceleration by belt pulley, be provided with wheel shaft supporting seat 14 in the front portion of motor 12, the wheel shaft two ends are equipped with big belt pulley 11 and braking mechanism (not shown) respectively, and big belt pulley 11 is connected with small belt pulley on the motor 12 by belt; Crank 10 is connected as a single entity with big belt pulley 11,180 ° each other of crank extending areas, both sides, and be connected with the driving reverse wheel 7 at frame 9 tops by flexible rope 13,13a respectively, flexible rope 13,13a can adopt wire rope, also can adopt broadband type; The sidepiece of frame 9 is provided with pulley yoke 4, and the balance weight wire rope on the head sheave 6 connects balance weight 2 by the pulley 4a on the pulley yoke 4; On frame 9, be provided with the cat ladder 3 that leads to workbench 5.This cat ladder 3 can play the effect of supplemental support frame, in order to increase the stability of frame 9.This machine utilizes reducing motor directly to drive after one-level is slowed down, and structurally given up reduction box, moving link get on to have disappeared former head sheave type oil pumper roller bearing travel prolongation mechanism, connecting rod, guide guide rail and idler wheel mechanism into, the minimizing of structural member, movement parts is more simplified its complete machine structure thus.This machine operating principle is: motor 12 drives the crank belt pulley 10,11 of circular motion by small belt pulley, and by flexible rope 13,7 rotations of 13a drive driving reverse wheel, do the oscillating motion of simple harmonic quantity formula through loading wheel head sheave 6, pump thereby drive sucker rod 8.Owing to be provided with pulley yoke 4 in that frame 9 sides are other, cat ladder 3, one has increased the stability of frame 9, the 2nd, enlarged the locus of adjusting balance weight 2, and made things convenient for the operating personnel.
