Beam-pumping unit swing balance device

Abstract

The invention discloses a beam-pumping unit swing balance device. The device comprises a device base, a reduction box, a balancing mechanism, a walking beam and a reduction box pulley, wherein the reduction box is mounted on one side of the bottom end of the device base, the reduction box pulley is mounted on one side of the surface of the reduction box, a crank is mounted on the surface of the reduction box on one side of the reduction box pulley, one side of the surface of the crank is provided with a connecting rod in a hinged mode, one side of the top end of the crank is provided with thebalancing mechanism, one side of the bottom end of the device base is provided with a lower support, the center position of the top end of the lower support is fixedly provided with a supporting plate, the center position of the top end of the supporting plate is provided with an upper support, the bottom end of the upper support extends out of the supporting plate and is in sliding connection with the outer wall of the lower support, and one side of the top end of the upper support is connected with the walking beam in a hinged mode. According to the device, the labor intensity of workers isreduced, the practicability of the device is improved, and the balance effect of the device is further improved.

Description

technical field [0001] The invention relates to the technical field of swing balance devices, in particular to swing balance devices for beam pumping units. Background technique [0002] In oil extraction, the beam pumping unit is a commonly used mechanical oil recovery equipment in the oil field. In order to reduce the motor power and the output torque of the reducer, and reduce the force on each transmission part of the pumping unit, it is necessary to install the pumping unit on the crank or beam Add balance weights to balance oil well load. [0003] There are many kinds of such swing balancing devices on the market today, which can basically meet people's needs for use, but there are still certain deficiencies, and the specific problems have the following points. [0004] (1) Most of the supports of the swing balance device of the existing beam pumping unit are assembled by splicing, and its height is inconvenient to adjust after the assembly is completed, resulting in ...
