Abstract
The utility model belongs to a pumping unit used in the petroleum engineering, which is provided with a lever walking beam, a working head, a bracket, a speed reducer, and an electric motor; a body bracket (3) is fixed on a body base (16) and the top end of the bracket (3) is connected with the midpoint of a walking beam (7). The key point is that one end of the walking beam (7) is provided with a prepositional working head (6) and the other end is provided with a postpositional working head (8). A speed reducer (15) for the dynamic transmission drives a reinforcing bull wheel (13), and one end of the driving connecting bar (17) is connected with the reinforcing bull wheel (13). One end of the two power arms (4) is respectively hinged with the two ends of the walking beam, and the other end of the two power arms is hinged with the other end of the driving connecting bar (17). Two working heads, equidistant to a fulcrum, are arranged on two ends of the walking beam to be balanced. One pumping unit can afford two oil wells to work with half reduced cost and electricity by change the dimension of the walking beam or one afford one oil well uses one pumping unit.
Description
Technical field
The utility model belongs to oil-well drilling equipment, particularly a kind of oil pumper that crude oil is extracted under the oil well ground that is used in the stripper.
Background technology
Crude oil production is continued to use beam pumping unit in decades always.When this beam pumping unit was worked, with big power drive reductor, the deceleration arbor was turned round and is driven crank load (load is big, the power consumption is high, the reductor life-span is short), by connecting rod, drive walking beam move up and down (internal resistance is big), thereby make oil pumping liquid polished rod, do up-down stroke, reach the purpose of oil pumping.There are a lot of problems in this traditional type, and the most outstanding is exactly the equilibrium problem of counterweight and load.In decades, many experts and scholars concentrate on studies to this, have developed many new types, but remaining uneven and bigger starting duty just must be started with more powerful motor.
Summary of the invention
The utility model is intended to learn wildly from other's strong points, and the design scheme of applied science is utilized classic balance theory, to have overcome bigger starting duty moment, and easily starting, smooth operation.And according to science take out the journey speed designs, can realize energy-efficiently, improve degree of filling, improve oil production.
Specifically, a kind of pair of horse head full-balance oil pumper, its body rack (3) are fixed on the body bearing (16), and the top of body rack (3) is connected with walking beam (7) mid point, end at walking beam (7) is fixed with preposition horse head (6), and walking beam (7) other end is fixed with rearmounted horse head (8); The reductor of transferring power (15) drives reinforcement bull wheel (13) and drive link (17) one ends are connected on the reinforcement bull wheel (13), and an end of two power arms (4) is hinged with the walking beam two ends respectively, and the other end is hinged with drive link (17) other end together.
The utility model is the twice that is designed to walking beam (7) with the length of power arm (4).Can reach laborsaving half purpose.
The kind of drive that the utility model adopts can be belt transmission, but first-selected gear drive.At this moment reinforcement bull wheel (13) is a gear wheel, and with reductor on output pinion (14) engagement.
Compared with the prior art, characteristics of the present utility model are embodied in:
1. the walking beam two ends are provided with two horse heads, and equidistant apart from fulcrum, load balance.One machine can be for two mouthfuls of oil well work (change the walking beam size, so just can save one times of financial resources, electric power), or counterweight, a well one machine, flexible Application.
2. the reductor output no longer adds counterweight, and the reductor load is reduced, and utilizes more low power motor, can drive this type, thereby reach economize on electricity, labour-saving purpose.
3. by the reasonable combination of large and small gear train, changed the mode of exerting oneself, the power of reductor output has directly driven the running of gear wheel, the mutual conversion of large and small gear, reduce running speed, improved and used force efficiency, increased the application life of reductor and axle.
4. after having adopted two horse heads, full balance mode, in the course of the work, only need disequilibrate, just can realize oil pumping.And on this basis, this machine utilizes simple mechanics-based principle, and the power arm of design is the twice of its resistance arm length, therefore, only needs the power of half, and just this machine runs well.

9, back oil well polished rod lifting rope, counterweight lifting rope
The specific embodiment
The utility model concrete structure is the same with existing oil pumper to have lever walking beam, horse head, support, reductor, motor, body rack (3) is fixed on the body bearing (16), the top of body rack (3) is connected with walking beam (7) mid point, its key is that the end at walking beam (7) is fixed with preposition horse head (6), and walking beam (7) other end is fixed with rearmounted horse head (8); The reductor of transferring power (15) drives reinforcement bull wheel (13) and drive link (17) one ends are connected on the reinforcement bull wheel (13), and an end of two power arms (4) is hinged with the walking beam two ends respectively, and the other end is hinged with drive link (17) other end together.The length of power arm (4) is for being designed to the twice of walking beam (7).Reinforcement bull wheel (13) is a gear wheel, and with reductor on output pinion (14) engagement.
Operating principle:
The utility model is by petty action rate motor starting, drive reductor through belt, the power of reductor output, (what alleviated the deceleration arbor turns round drive and resistance directly to drive afterburning gear wheel, increased the life-span of power and reductor), by connecting rod, promote the lengthening power arm (power arm is the twice of resistance arm, laborsaving half, save power), make the power arm swing, thereby make the walking beam up-down stroke, drive oil pumping liquid polished rod and carry out oil pumping work.
