Description
Technical Field
The invention relates to the field of oil fields, in particular to a walking-beam-free oil pumping unit using a speed reducer and a motor as counterweights.
Background
In the field of oil extraction in oil fields, mechanical pumping is a common pumping unit, which comprises a walking beam, a horse head, a bracket, a beam, a connecting rod, a base, a crank, a balance block, a reduction gearbox, a motor and the like, wherein the balance of the pumping unit is mainly realized by the crank and the balance block, and the reduction gearbox and the motor are only used as driving devices.
Disclosure of Invention
In order to overcome the defects that the prior pumping unit has large energy consumption in the operation process and the running of the crank and the balance block have unsafe hidden trouble, the invention provides the walking-beam-free pumping unit which uses the speed reducer and the motor as the balance weights.
The technical scheme of the invention is as follows: a walking-beam-free pumping unit using a speed reducer and a motor as counterweights comprises a base and a steel wire rope, wherein a middle base is fixed at the front end of the base, a power base is hinged to the middle base, the motor and the speed reducer are fixed on the upper portion of the power base, an output shaft of the speed reducer is connected with a crank, a connecting rod is connected to the crank through a rotating shaft, and the other end of the connecting rod is connected with the base through a crank pin; the upper part of the power machine base is fixed with a swinging wheel, the front end of the base is also fixed with a support, the top part of the support is respectively connected with a rear wheel and a front wheel, and a steel wire rope sequentially bypasses the front wheel and the rear wheel and then is fixed on the swinging wheel at the end part.
The invention has the following beneficial effects: by adopting the scheme, the reduction gearbox and the motor are fixed at the upper part of the power machine base and are directly used for balancing the pumping unit as the main balance weight, so that the weight of the pumping unit is reduced; the flexible steel wire rope is connected with the pumping rod, so that the pumping unit has a simple structure; the end of the power machine seat is balanced and adjusted by ore, so that the adjustment is convenient and the anti-theft effect is good.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure, 1-rope suspension device, 2-steel wire rope, 3-front wheel, 4-supporting arm, 5-support, 6-rear wheel, 7-swinging wheel, 8-crank, 9-speed reducer, 10-belt, 11-motor, 12-power machine base, 13-connecting rod, 14-crank pin, 15-base, 16-middle base and 17-square support.
Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in figure 1, the walking-beam-free pumping unit using the speed reducer and the motor as the balance weight comprises a base 15 and a steel wire rope 2, wherein a middle seat 16 is fixed at the front end of the base 15, a square support 17 is hinged on the middle seat 16, so that the square support 17 and the middle seat 16 can freely rotate, and a power base 12 is fixed on the upper portion of the square support 17. The power base 12 is in a long strip shape, a motor 11 and a speed reducer 9 are fixed behind the upper portion of the power base 12, the motor 11 is connected with the speed reducer 9 through a belt 10, an output shaft of the speed reducer 9 is connected with a crank 8, the crank 8 is connected with a connecting rod 13 through a rotating shaft, and the other end of the connecting rod 13 is connected with a base 15 through a crank pin 14. And a swinging wheel 7 is fixed at the middle section of the upper part of the power machine base 12. The support 5 is still fixed with to 15 front ends of base, and the rear end at support 5 top is fixed with rear wheel 6, and one section cantilever is connected to support 5 top front end, and the cantilever front end is fixed with front wheel 3, and the front end rim of front wheel 3 is adjusted well with the well head, and is connected with support arm 4 between cantilever bottom and the support 5. The wellhead end of the steel wire rope 2 is connected with a rope hanger 1, and the other end of the steel wire rope sequentially bypasses the front wheel 3 and the rear wheel 6 and is fixed on the swinging wheel 7 at the end part.
When the oil pumping machine works, ores or balancing weights are placed at the rear end of the power machine base 12 to serve as balance weights according to specific parameters of the oil pumping machine and a well head. When the motor 11 rotates, the speed reducer 9 can be driven by the belt 10 to rotate the crank 8, and then the power base 12 is driven by the connecting rod 13 to do swing rod motion, so that the swing wheel 7 does swing rod motion, the steel wire rope is driven, the sucker rod does up-and-down reciprocating motion, and the oil extraction function is realized.
