Abstract
The invention provides an oil pumping unit with a built-in speed reducer, comprising a base and a tower located on the base, wherein a tower top platform is arranged at the top end of the tower, a drum bin is arranged on the tower top platform, a speed-regulating and reversing motor is arranged outside the drum bin and used for realizing power input and reversing, a drum is arranged in the drum bin, and a speed reducer is arranged in the drum; a transmission belt is wound on the drum, one end of the transmission belt is connected with a rope hanger via a pulley block, a hanging rod is arranged below the rope hanger, and the hanging rod is connected with a downhole weight; and the other end of the transmission belt is connected with a weight box via a guide wheel which is arranged at one side of the tower top platform. The oil pumping unit provided by the invention has the beneficial effects of being long in effective stroke, high in transmission efficiency, high in electricity-saving rate which achieves 40% compared with the electricity-saving rate of a walking-beam oil pumping unit, capable of bearing a heavy load, and capable of being used in various well conditions.
Description
Technical field
The invention belongs to oil recovery ground machine equipment technical field, especially relate to the built-in oil pumper of a kind of reducer.
Background technology
Oil pumper in the existing technology mostly is beam pumping unit.The motor direction operation of this oil pumper, driving the bearing pin of walking beam on carrier base through belt gearing, gear reduction unit and quadric chain swings repeatedly, by suspension arrangement, jamming rod device, polished rod, sucker rod and balancing weight Compositional balance actuating system, make the underground reciprocating oil well pump carry out the oil pumping work of upper and lower motion again.This beam pumping unit is that high rotating speed is transferred to the slow-speed of revolution by deceleration device, changes rectilinear motion into by linkage again, has that transmission efficiency is low, energy consumption is large, bear the technical problems such as the heavy load ability is low.
Summary of the invention
The problem to be solved in the present invention provides that a kind of transmission efficiency is high, energy consumption is little, effective stroke is long and can bear the built-in oil pumper of reducer of heavy load.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the built-in oil pumper of a kind of reducer, comprise base, be positioned at the pylon on the base, the pylon top is provided with a cat head platform, and described cat head platform is provided with the cylinder storehouse, described cylinder is provided with the speed governing reversing motor outside the storehouse, realize power input and commutation, described cylinder is provided with cylinder in the storehouse, is provided with reducer in the described cylinder; Twine driving-belt on the described cylinder, an end of described driving-belt links to each other with polished rod eye through assembly pulley, and described polished rod eye has suspension rod, and described suspension rod links to each other with down-hole weight; The other end of described driving-belt links to each other with a ballast box by the directive wheel that described cat head platform one side arranges.
Further, have four circle groove structures on the outer cylinder body of described cylinder.
Described assembly pulley can be fixed pulley group or running block.
Described ballast box also is furnished with the counterweight counterweight, the adjustable weight quality.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, the effective stroke of this oil pumper is long, transmission efficiency is high, compares economize on electricity with beam pumping unit and reaches 40%, and can bear heavy load, can use under multiple hole condition.

The specific embodiment
As shown in Figure 1, the present invention includes base 1, be positioned at the pylon 2 on the base 1, pylon 2 tops are provided with a cat head platform 3, and wherein, pylon 2 places a side of well head, is convenient to safeguard oil well operation, and simultaneously, pylon 2 can be realized whole installation and removal.
Polished rod eye 9 has suspension rod 12, and suspension rod 12 links to each other with down-hole weight 10; The other end of driving-belt 7 links to each other with a ballast box 11 by the directive wheel 13 that cat head platform 3 one sides arrange, and this ballast box 11 also is furnished with the counterweight counterweight, and the adjustable weight quality moves reciprocatingly oil pumper, and realizes accurate balance.
As shown in Figure 2, the four circle groove structures that have on the outer cylinder body of cylinder 5, a groove is for band-type brake, and a groove is for the polished end driving-belt, and two grooves are for driving-belt, and groove depth satisfies the thickness that the polished rod range is involved in driving-belt 7.
The driving mechanism of the built-in oil pumper of this reducer is positioned at pylon 2 tops, increases the length that stroke only need change height and the driving-belt 7 of pylon 2, need not any change is done by polished rod mechanism; Reducer places cylinder 5 inner directly head rolls 5 in addition, drives driving-belt 7 and polished rod, has cancelled complicated linkage, thereby has increased the transmission efficiency of whole system.
Above one embodiment of the present of invention are had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limiting practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
