An electrically driven motor base adjuster

Abstract

The invention belongs to the field of pumping unit accessory equipment, and particularly relates to an electrically-driven motor base adjuster which comprises an upper plate and a lower plate, a driving mechanism is arranged between the upper plate and the lower plate, and the driving mechanism between the upper plate and the lower plate is a lifting mechanism. The lifting mechanism structurally comprises a driving shaft, a connecting body A, a connecting body B and a connecting rod, the connecting body A and the connecting body B are respectively connected to the outer sides of the left-handthread section and the right-hand thread section through threads; the connecting body A and the upper plate, the connecting body A and the lower plate, the connecting body B and the upper plate, and the connecting body B and the lower plate are connected through the connecting rods respectively; and the connecting rods form a space truss structure with a triangular unit between the upper plate andthe lower plate. According to the invention, the multi-connected truss structure with a plurality of triangular units is arranged, so that the motor of the oil pumping unit is stably supported whileascending and descending, and meanwhile, the motion precision in the ascending and descending process is ensured.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment of pumping units, in particular to an electrically driven motor base adjuster. Background technique [0002] In my country's petroleum industry production, the beam pumping unit is a mainstream oil production equipment. The beam pumping unit is equipped with a high-power motor and a reducer, and the power connection between the motor and the reducer is realized through a belt and a pulley. The belt will loosen slightly after being used for a period of time under heavy load conditions, resulting in accelerated belt wear, shortened belt life, and reduced mechanical efficiency. In addition, in the cold areas of northern my country, the temperature difference between winter and summer is large, and the belt is more likely to loosen under the action of thermal expansion and contraction. Therefore, workers often need to fine-tune the installation position of the motor. [0003] After searching, the...

Problems solved by technology

[0003] After searching, there are already some motor bases that can fine-tune the motor position in other fields, but these motor base products are all used in the way of horizontal adjustment. If it is applied to the beam pumping unit, the gravity of the motor itself will It cannot contribute to the support stability of the motor base, which makes it difficult to guarantee the support stability of the movable base, resulting in loud noise and severe vibration during the working process of the motor, which seriously damages the service life of the motor and auxiliary structures such as belts
