Abstract

A single-rod double-headed energy-saving oil pumping unit with simple structure and reliable performance is provided to overcome deficiencies of a beam-pumping unit and various energy-saving oil pumping units in the prior art. The technical scheme of the single-rod double-headed energy-saving oil pumping unit is that a motor and a reduction box are arranged on a rack pedestal; the motor is mounted in the middle part of a rack; the reduction box is arranged upmost of the rack; two ends of an output shaft of the reduction box are respectively provided with a pair of horse heads, namely a front horse head and a back horse head; the front horse head is arc-shaped; steel wire winded on the front horse head drives a polish rod to move via a beam hanger; the back horse head is an involute or other molded lines facilitating energy conversation; and a steel wire winded on the back horse head can be directly connected with a balance weight. Positive and reserve rotation of the output shaft of the reduction box is driven by positive and reverse rotation of the motor, so up and down reciprocate movements of the polish rod are driven; and the oil pumping unit is characterized by safety, reliable and better energy-saving effect.

Description

Single pole double end energy-saving pumping unit
Technical field
The utility model relates to the oil pumper that a kind of oil field machinery oil is used, and specifically, relates to single pole double end energy-saving pumping unit, belongs to mechanical oil recovery field.。
Background technology
The capital equipment of oil extraction in oil field is beam pumping unit both at home and abroad, structure as shown in Figure 1, mainly formed by parts such as motor (1), reduction box (2), crank (3), balance weight (4), connecting rod (5), walking beam (6), support (7), horse head (8) and wire rope (9), it is a kind of quadric chain, the existing century-old history of application, its great advantage is dependable performance, but the shortcoming such as it exists counterbalance effect poor, and system effectiveness is low.For further reducing the energy consumption of oil pumper, the scientific research institutions such as oil field scientific and technical personnel and colleges and universities have carried out continuous research and discovery, develop the energy-saving pumping unit of various types, as pylon oil pumper, friction reversing pumping unit, numerically controlled beam-pumping units etc., though these oil pumpers have certain energy-saving effect, the problem of its poor reliability is never solved well.
Summary of the invention
The purpose of this utility model is exactly the defect for existing beam-pumping unit and various energy-saving pumping units, provides a kind of simple in structure, and manipulation is convenient, the single pole double end energy-saving pumping unit of dependable performance.
Its technical scheme is: mounted motor and reduction box in gantry base, motor is at the middle part of frame, reduction box is in the top of frame, two pairs of horse heads are installed on the output shaft of reducer, and a pair of is front horse head, and a pair of is rear horse head, front horse head is circular arc type, drive polished rod motion around front wire rope thereon by polished rod eye, rear horse head is involute, is directly connected with counterweight around rear wire rope thereon.Move and drive the output shaft rotating of reducer by motor positive and inverse, thereby drive polished rod to move up and down.
The utility model has the advantages that:
1. compared with beam pumping unit, become single pole structure from quadric chain, transmission efficiency obviously improves.
Balance weight directly and polished rod load balance each other, good balance effect, balance efficiency is high.
3. rear horse head is particular design molded line, can further improve counterbalance effect, reduces motor output torque.
4. because complete machine structure is simplified and balance material can, without ferrous materials, can reduce steel materials, reduce production costs.
5. motor is as adopted switched reluctance machines, accurate, eternal for the control and regulation that come and go number of times, can further improve system effectiveness.
6. adopt the reduction box of existing beam-pumping unit and the mobile phone structure of stopping, performance safety is reliable.
7. structurally more easily realize long stroke
8. complete machine structure is rationally distributed, facilitates installation and maintenance.
Brief description of the drawings: accompanying drawing 1 is existing beam pumping unit structure diagram.
Accompanying drawing 2 is the utility model structure diagrams.
Detailed description of the invention: the utility model is described in further detail below in conjunction with accompanying drawing 2
At the upper reducer (2) of installing of frame (10), two pairs of horse heads of the upper installation of output shaft (11) of reducer (2), a pair of is front horse head (12), a pair of is rear horse head (13), and front horse head (12) is connected with polished rod and is realized oil pumping action by front wire rope (9).Rear horse head (13) is connected with counterweight (15) by rear wire rope (14).Motor (1) is arranged on the middle part of frame (10), motor (1) drives output shaft (11) the rotating campaign of reducer (2) by rotating campaign, thereby drive polished rod to move up and down, because front horse head (12) and rear horse head (13) are all fixed on the output shaft (11) of reducer (2), front horse head (12) and rear horse head (13) can be considered a bar, the molded line of front horse head (12) is circular arc line, the molded line of rear horse head (13) is involute, therefore, this oil pumper can called after single pole double end energy-saving pumping unit.
