Problems solved by technology

[0002] At present, the most widely used oil production equipment at home and abroad is the beam pumping unit. This type of pumping unit has a simple structure and is convenient for on-site maintenance. However, due to the inherent characteristics of the four-bar linkage mechanism of the pumping unit, its transmission chain is relatively long. Low mechanical efficiency, generally suitable for short strokes, for long strokes, the height of the pumping unit will be increased, and the gearbox and crankshaft torque will increase proportionally, thus increasing the energy consumption of the pumping unit
Foreign long-stroke pumping units have developed rapidly, and the representative ones are the American ROTAFELEX long-stroke pumping units and the LCJ long-stroke pumping units developed in my country. The dynamic load reduces the life of the chain, so the failure is frequent, the reliability is poor, and the cost is high

Embodiment Construction

[0013] The present invention further illustrates the utility model with specific embodiments in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following specific embodiments.

[0014] The fully balanced long-stroke pumping unit provided by the present invention includes: installing a motor (7), an automatic brake (27), a speed reducer (6), and a speed reducer input and output shaft on the top platform (8) of the frame (2) Coupled (26), (25), sky wheel assembly (5) (bearing block 22, bearing 23, sky wheel shaft 24). During work, on the stroke, the motor (7) rotates forward (clockwise in Figure 1), through the automatic brake (27), the reducer input shaft coupling (26), the reducer (6), the reducer output coupling Joint (25), sky wheel axle (24), sky wheel (5) rotates clockwise, thereby traction rope (4) drives polished rod (19) to promote by rope hanger (3). Downstroke, the motor (7) reverses (counterclockwis...

Abstract

This invention provides balance long impact oil extraction device, which comprises motor, automatic brake, decelerator input axis, decelerator, decelerator output axis and sheave parts on shell top platform, wherein, the drive rope is connected to hanging device and ring through drive rope fix device two end set inside sheave parts; the hanging rope and ring are connected through light bar and match parts; when sheave rotates, it drives rope and match drive rope for synchronous reverse movement.

Description

technical field [0001] The invention belongs to the technical field of oil production machinery and equipment, in particular to a fully balanced long-stroke pumping unit. Background technique [0002] At present, the most widely used oil production equipment at home and abroad is the beam pumping unit. This type of pumping unit has a simple structure and is convenient for on-site maintenance. However, due to the inherent characteristics of the four-bar linkage mechanism of the pumping unit, its transmission chain is relatively long. The mechanical efficiency is low, and it is generally suitable for short strokes. For long strokes, the height of the pumping unit will be increased, and the gearbox and crankshaft torque will increase proportionally, thereby increasing the energy consumption of the pumping unit. Foreign long-stroke pumping units have developed rapidly, and the representative ones are the American ROTAFELEX long-stroke pumping units and the LCJ long-stroke pumpin...
