Abstract
The utility model discloses an oil pumping unit and relates to an oil exploitation device. The oil pumping device comprises a pumping head, a walking beam, a connecting rod mechanism, a speed reducer, a motor, a support and a base. A belt pulley drive unit is arranged between the motor and the speed reducer. A balance block is arranged at one end, away from the pumping head, of the walking beam. Compared with the prior art, the oil pumping unit can enable protected oil pumping unit stroke times to be adjusted according to the requirement, enable the walking beam to be stable and high in efficiency.
Description
Technical field
The utility model relates to a kind of oil exploitation device, particularly a kind of oil pumper.
Background technology
Beam pumping unit is comprised of horse head, walking beam, linkage, reducer, motor, support and base usually, it is the transmission of one-level belt pulley between motor and reducer, therefore oil pumper has fixing stroke range, 4-8 time per minute, its weak point is that number of strokes can not be adjusted, be unwell to needs and adjust the occasion of number of strokes, as the exploitation of heavy oil wells.On the other hand, its walking beam can not keep balance.
Summary of the invention
For above-mentioned weak point, the purpose of this utility model just is to provide a kind of oil pumper, and this oil pumper number of strokes can be adjusted as required, and walking beam is steady.
The technical solution of the utility model is: a kind of oil pumper, comprise horse head, walking beam, linkage, reducer, motor, support and base, be provided with the belt pulley transmission group between described motor and described reducer, described walking beam is provided with balance weight away from described horse head one end.
As preferably, described walking beam is the i-beam structure walking beam.
Compared with prior art, the beneficial effects of the utility model are: make transmission become the second belt transmission because be provided with the belt pulley transmission group between motor and reducer, therefore can change number of strokes as long as change the size of belt pulley, thereby the output of oil well is improved, and transmission efficiency reaches 92%.And balance weight can beam balance.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of oil pumper comprises horse head 3, walking beam 4, linkage 5, reducer 6, motor 7, support 2 and base 1, is provided with the belt pulley transmission group between motor 7 and reducer 6, and walking beam 4 is provided with balance weight 8 away from horse head 3 one ends.
The belt pulley transmission group is big belt pulley 9 and small belt pulley 11.During assembly and connection, big belt pulley 9 use belts are connected with motor pulley 10, and small belt pulley 11 is connected with reducer pulley 12 use belts, thereby becomes the second belt transmission.
Walking beam 4 is the i-beam structure walking beam.
Above-mentioned embodiment is only as explanation of the present utility model and unrestricted; the utility model protection domain also should comprise those apparent conversions to those skilled in the art, conversion, variation or substitute; and in the ken that those of ordinary skills possess, can also make various variations under the prerequisite that does not break away from this utility model aim.
Claims (2)
1. oil pumper, comprise horse head, walking beam, linkage, reducer, motor, support and base, it is characterized in that: be provided with the belt pulley transmission group between described motor and described reducer, described walking beam is provided with balance weight away from described horse head one end.
2. oil pumper according to claim 1, it is characterized in that: described walking beam is the i-beam structure walking beam.
