Description

The rotary-type pumping unit of long stroke

The utility model relates to the rotary-type pumping unit of a kind of long stroke.

Traditional pumping unit is the sliding beam structure of crank-type, tradition pumping unit volume is big, floor space is big, and stroke is less, is generally four meters, because stroke is little, just need more number of strokes so extract the oil of same volume out, life-span at oil producing operation process middle sleeve, oil pipe sucker rod and pump is shorter, has increased maintenance load, has also strengthened cost for oil production.

The purpose of this utility model is in order to overcome above-mentioned deficiency, and designs a kind of rotary-type pumping unit of long stroke of the no walking beam of being made up of motor, drive mechanism, bent axle, connecting rod, commutator and runner.

The utility model content: the rotary-type pumping unit of a kind of long stroke, comprise motor, belt gear, speed reducer, crank, connecting rod, wire rope and sucker rod, motor passes through belt gear, speed reducer drives crank, crank is by the crank pin drivening rod, it is characterized in that: the other end of connecting rod is provided with crossbeam, connector is equipped with at the middle part of crossbeam, connector is fixed on the commutator, commutator is by rotating shaft, housing, incomplete internal gear piece, planet wheel, the bearing support that central gear and two dunnages are formed is formed, incomplete internal gear piece is fixed on the inner walls of commutator, planet wheel respectively with the internal tooth of incomplete internal gear piece and central gear engagement, planet wheel is loaded in the rotating shaft of bearing support one end, both can relatively rotate, the other end of bearing support is fixed on the axle sleeve, and described axle sleeve is made as two sections, lays respectively at the central gear two ends and is sleeved on the main shaft, both can relatively rotate, and also are fixed with central gear and runner on the main shaft; In the support of main shaft two supports on being fixed in base.Runner is made as two bodies, is connected as a single entity by the hinge fastening piece.

The utlity model has following advantage:

1. the stroke of the rotary-type pumping unit of long stroke is a 6-18 rice, so when extracting the oil mass of same volume, number of strokes is few, has improved the life-span of sleeve pipe, oil pipe, sucker rod and pump exponentially, has reduced cost for oil production.

2. adopted the commutator of forming by internal gear piece, planet wheel and central gear owing to the rotary-type pumping unit of long stroke, compact structure, volume is little, and floor space is little.

3. because rotor design is two-part and connecting as one with hinge, fastening piece, being convenient to maintenance, can be that axle folds with runner with the hinge during maintenance, abdicates the space on well head top, can keep in repair, very convenient.

Description of drawings:

Fig. 1 is the utility model schematic representation;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 2.

Further specify the utility model below in conjunction with drawings and Examples.

Please referring to Fig. 1, Fig. 2, the rotary-type pumping unit of long stroke is made up of main part such as base 1, motor 2, belt gear 3, gearbox 4, crank 5, equilibrium block 6, crank pin 7, support 8, connecting rod 9, crossbeam 10, wire rope 11, main shaft 12, commutator 13 and runner 14, and motor, braking mechanism, gear shift base and support all are fixed on the base.Motor drives gearbox through belt gear, the output shaft of gearbox is provided with crank, be connected through crank pin between crank and connecting rod, the other end of connecting rod is equipped with crossbeam, the middle part suit of crossbeam connector 25, and connector is fixedlyed connected with the housing 15 of commutator, commutator is made up of housing 15, central gear 16, planet wheel 23, internal gear piece 24, rotating shaft 22 and bearing support 21; Planet wheel meshes (Fig. 3) with internal gear piece, central gear respectively; Central gear is fixed on the main shaft 18 by flat key 19; In the rotating shaft of the bearing support that is made of two support plates planet wheel is housed, the other end of bearing support is loaded on the axle sleeve 17 by flat key 20, and axle sleeve 17,27 all is contained on the main shaft, and lays respectively at the two ends of central gear, and axle sleeve can rotate relative to main shaft; Runner 14 also is housed on the main shaft and, makes main shaft drive the positive and negative rotation of runner by flat key 26 connections; Commutator drives the swing that runner is made several angle by main shaft, and it is reciprocating to recover the oil that runner drives sucker rod by wire rope 11.The stroke of present embodiment is 12 meters, and it is three times of traditional pumping unit, has increased substantially the life-span of sleeve pipe, oil pipe, sucker rod and pump, has reduced cost for oil production; Runner makes to be two bodies and to be linked as an integral body by hinge and fastening piece, during maintenance runner is folded up the space of abdicating well head top and can carry out, very convenient.
