Problems solved by technology

However, the pulley of the field pumping unit is exposed to the outside and is easy to rust, and the threaded connection of the fixed pulley and the tapered connection between the pulley and the shaft are usually rusted, so it is time-consuming and laborious to disassemble. 2-3 working days
Therefore, the gear shifting time of this pumping unit is long, the efficiency is low, and the operation is inconvenient, which has been unable to meet the development requirements of modern oil extraction technology.

Abstract

The invention relates to a stroke frequency regulating apparatus of an oil pumping machine, which belongs to the technical field of oil exploitation and extraction equipment and is characterized in that three synchronizing pinions (16), (12) and (11) and three variable speed pinions (15), (13) and (8) are arranged on an input shaft (9); three synchronizing gearwheels (17), (21) and (22) and three variable speed gearwheels (19), (20) and (23) are arranged on an output shaft (18); three pairs of synchronizing gears keep engaged all the time; and when a shifting handle (14) is screwed and a fork head (4) of a shifting fork is pressed, the fork head can be clamped in fork pockets on the three variable speed pinions (15), (13) and (8) on the input shaft (9), so that the variable speed pinions can be toggled to move axially and realize shift operation. The regulating apparatus has simple and compact structure and convenient manufacture and can fully adapt to shift demands under various conditions, and when the stroke frequency regulating apparatus is arranged on the oil pumping machine, the shift quality can be improved, and the shift time can be reduced.

Description

Technical field: [0001] The invention relates to a stroke rate regulator of a pumping unit, which belongs to the technical field of oil development and production equipment. Background technique: [0002] In the oil extraction process of the pumping unit in petroleum development, due to the influence of geological factors, oil properties, especially heavy oil wells and other factors, it is often necessary to change the stroke frequency of the pumping unit to improve production efficiency. [0003] Existing pumping units, such as conventional beam pumping units that adopt crank balance, can realize the requirements of different punching times during work by replacing the small pulley and triangular belt on the motor shaft. When realizing the required stroke times, the pumping unit is stopped, and then the small pulley is manually disassembled and replaced. However, the pulley of the field pumping unit is exposed to the outside and is easy to rust, and the threaded connection...
