Abstract

The invention discloses a belt wrap angle adjusting device for a pumping unit. The belt wrap angle adjusting device comprises a belt and a belt pressing device. The belt pressing device comprises an upper pressing wheel arranged on the upper side of the belt, and a lower pressing wheel arranged on the lower side of the belt. A wheel track adjusting device used for adjusting the distance between the upper pressing wheel and the lower pressing wheel is arranged between the upper pressing wheel and the lower pressing wheel. The tension degree of the belt is improved through extrusion of the upper pressing wheel and the lower pressing wheel, the wrap angle of the belt on a motor belt wheel and a speed reducer belt wheel is increased, the phenomenon of slippage of the belt is avoided, and oil well halt production due to belt damage caused by belt slippage is avoided.

Description

technical field

[0001] The invention relates to the technical field of oil pumping unit equipment, in particular to an oil pumping unit belt wrap angle adjustment device. Background technique

[0002] Oilfield pumping units need to use belt transmission devices. During the working process of oilfield pumping units, slippage between the belt and the pulley often occurs, which reduces the output of the oil well. In order to keep the belt from slipping and not loosening during use, the belt is required to maintain a large gap. Tension, so just need to often adjust the position of belt and pulley, the efficiency of adjustment method is low like this, has shortened the life-span of belt and pulley shaft, therefore, need a kind of easy to use, easy to operate belt wrap angle adjusting device. Contents of the invention

[0003] The object of the present invention is to overcome the above-mentioned shortcomings, and to provide a device for adjusting the wrapping angle of the belt ...
