A wire rope fastening mounting seat for a wheel pumping unit

Abstract

The invention discloses a steel wire rope fastening mounting seat of a wheel type pumping unit. The steel wire rope fastening mounting seat comprises steel wire ropes, a balance weight, a rope head box, sliders and two side plates. The two side plates are fixed on the balance weight. The rope head box is located between the two side plates which are fastened to the rope head box. The sliders corresponds to the steel wire ropes. The sliders are movably located in the rope head box. The top face of the rope head box is provided with rope holes, and the sliders are correspondingly located below the rope holes. The first end of each steel wire rope extends into rope head box through the corresponding rope hole, winds around the corresponding slider and extends out of the top face of the rope head box through the same rope hole. The first end of each steel wire rope is provided with a steel wire rope chuck. The rope head box is provided with a movement controller which can control the sliders to move up and down in the rope head box. The steel wire rope fastening mounting seat has the advantages that fixation and mounting of steel wire ropes and the balance weight is made simple, tension of the steel wire ropes can be adjusted to allow the same to be in balanced stress, and service life of each steel wire rope is prolonged.

Description

technical field [0001] The invention relates to oil mining machinery, in particular to a fastening installation seat used for fixed installation of a steel wire rope and a counterweight body of an oil pumping unit. Background technique [0002] Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine", which makes oil out of the well by pressurizing. The pumping unit commonly used in oil exploitation is a beam pumping unit at present, and this beam pumping unit is mainly composed of a beam, connecting rod, crank mechanism, reduction box, power equipment and auxiliary equipment. The pumping unit with this structure realizes the reciprocating motion of the sucker rod driven by the motor in the oil cylinder through the cooperation of the belt deceleration, gear and connecting rod mechanism, so that the pumping unit has the characteristics of large overall volume, low mechanical transmission efficiency and short stroke. Short and l...

Problems solved by technology

[0004] However, in the wheeled pumping unit of this kind of structure, its suspension rope (i.e. steel wire rope) is fixed on the counterweight body through the wire rope rigging. The weight of the heavy body is very heavy. Generally, several steel wire ropes are required to achieve the balance between the counterweight body and the sucker rod, and the length of each steel wire rope is relatively long, so it is difficult to adjust the tension between the steel wire ropes during installation (ie The length of the steel wire ropes between the sucker rod and the counterweight body) is the same, so that the stress on each steel wire rope is unbalanced, so that the steel wire rope with a higher tension in each steel wire rope is prone to breakage, shortening the service life of the steel wire rope
