Description

A kind of two stationary annular tooth bar tower-type pumping unit
Technical field
The utility model relates to a kind of two stationary annular tooth bar tower-type pumping unit, is the oil recovery machiner apparatus field belonging to industrial gas oil.
Background technology
Oil pumper is the main equipment of oil field machinery oil.Along with continually developing of petroleum resources, the degree of depth of exploitation oil reservoir constantly increases, and oil pumper is gradually towards maximizing and the future development of energy-saving.Current oil field has in rod-type oil recovery machiner equipment, mainly contains beam pumping unit, chain type oil pump, hydraulic oil pumping unit, long annular rack examination oil pumper etc.Beam pumping unit has that weight is large, energy consumption is high, stroke is short, when realizing long stroke, and the shortcomings such as physical dimension is large; Chain type oil pump has that poor reliability, changement are complicated, specific links and king-pin easily broken, be not suitable for the shortcomings such as heavy load; It is too complicated that hydraulic oil pumping unit has hydraulic system, adds the fault rate of Hydraulic Elements, and the shortcoming such as unavoidably to pollute due to the seepage of hydraulic oil; Chinese patent 200920019023.1 discloses a kind of utility model of long annular rack oil pumping machine by name, belongs to single rack type pumping machine; Connected by belt between motor and reducer, reducer and driving wheel can the horizontal slips when commutating.When commutating, because reducer can move horizontally along with driving wheel, and motor is fixed, when reducer will be caused like this to move to high order end or low order end with driving wheel, belt is opened very tight, and belt is very loose when centre position, this can have a huge impact the operating efficiency of oil pumper and stability; Annular rack and balance slide block pump to drive sucker rod, and realize oil pumping operation, when realizing long stroke, frame can be very high, oil pumper bad stability.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, a kind of two stationary annular tooth bar tower-type pumping unit is provided, this oil pumper has two annular racks, and the fixing on the ground of symmetry, motor and reducer to be arranged in reversing gear bracket and to follow reversing gear bracket and move together with round frame, motor and reducer can be used as a part of balance weight, come and go pumping of frame and realize oil pumping operation.When realizing long stroke, bracket height is low, the advantage that reliability is high, and solves the degree of tightness variation issue of belt when adopting belt transmission, improves the efficiency of oil pumper.
The technical scheme that the utility model adopts is:
A kind of two stationary annular tooth bar tower-type pumping unit of the utility model, primarily of motor, reducer, reversing gear bracket, comes and goes frame, annular rack, annular gathering sill, pinion, frame, wire rope, crown sheave, polished rod eye, balance weight composition.Described frame is installed on ground, and frame bilateral symmetry is placed with the annular gathering sill being fixed to ground, and annular rack is fixed on annular gathering sill; Described round frame is positioned over inside frame, and can be pumped along frame by vertical wheel, realizes oil pumping operation; Round frame is divided into two-layer, and reversing gear bracket is placed in top, and balance weight is placed in below; Described reversing gear bracket is placed and is come and gone frame top, and by horizontal roller can in round frame bilateral reciprocation, realize commutation; Reversing gear bracket is divided into two-layer, and top is fixed with reducer, and below is fixed with motor, middle by belt transmission.Respectively there are 4 horizontal rollers the upper and lower both sides of reversing gear bracket, and round frame each side has 4 vertical wheel.
Motor export rotary motion through belt transmission to reducer, under the drive of reducer output shaft, pinion rotates, drive reducer, directive wheel, motor, reversing gear bracket, round frame pump, if pinion rotates clockwise on the left of annular rack, then come and go frame to move upward, polished rod moves downward, and is down stroke; Through commutation, pinion rotates clockwise on the right side of annular rack, then come and go frame and move downward, polished rod moves upward, and is upstroke.The directive wheel that diameter is slightly large and pinion are coaxially installed, and can freely rotate, but by the constraint of annular gathering sill, and under the constraint of directive wheel and annular gathering sill, pinion and annular rack can keep good engaging all the time.At pinion while the top and bottom semi-circular portion of annular rack makes gear motion, reversing gear bracket does transverse movement, realizes commutation.The top rail coming and going frame is connected to the wire rope walking around crown sheave, drives oil well pump by polished rod eye and polished rod, can realize operation of pumping.
Compared with prior art, advantage of the present utility model:
1, annular rack is fixed on ground, and pinion drives round frame to pump, and greatly reduces oil pumper height, easily realizes long stroke; 2, two annular rack symmetries are installed on frame both sides, reasonable stress, and supporting capacity is large; 3, motor and reducer are followed together with round frame and are moved up and down, and can be used as a part of balance weight, and do not exist there is belt tension variation issue as long annular rack oil pumping machine, improve the efficiency of oil pumper; 4, belt transmission is flexible driving, has the effect of buffering absorbing, effectively can protect motor, improves the application life of motor.5, there is structure simply novel.
