Abstract
The utility model relates to a non-beam pumping unit with a variable-diameter crown sheave. The pumping unit provided by the utility model mainly comprises a small belt, a base, a support pull rod, a beam hanger, a rack, a large belt and the variable-diameter crown sheave; a crank is installed on an output shaft of a speed reducing box and is provided a crank balancing weight; the other end of the crank is sequentially connected with a connecting rod and one end of the small belt; the other end of the small belt is installed on a minor-radius wheel of the variable-diameter crown sheave; one end of the large belt is installed on a large minor-radius wheel of the variable-diameter crown sheave; the other end of the large belt is connected with the beam hanger; the rack is installed on the base; the variable-diameter crown sheave is installed at the top end of the rack; one end of the support pull rod is connected with the upper part of the rack; and the other end of the support pull rod is connected with the base; the speed reducing box and drive motors are arranged on the base; and a transmission belt is installed on the speed reducing box and the drive motors. The pumping unit provided by the utility model has the characteristics that the structure is simple, the beam is eliminated, a transmission system is simplified, the systematic efficiency is high, the energy conservation effect is obvious, the rack can move without using equipment, the workover operation is fast and convenient, etc. Therefore, the pumping unit is widely applied to mechanical oil production engineering in oil exploitation.
Description
Technical field
The utility model patent relates to the ground pumping unit of oil exploitation, particularly a kind of reducing crown sheave blue elephant.
Background technology
As everyone knows; Traditional oil pumper is generally the beam type structure; Contribute share for the mechanical type petroleum production engineering always; But it exists following shortcoming or deficiency simultaneously: 1. receive the restriction of transmission device gearratio, generally adopt short stroke, the fast jig frequency mode of production to recover the oil, can't satisfy the requirement that hyposmosis, stripper well are taken out long stroke, low jig frequency deeply; 2. transmission efficiency is low, and power consumption is big; 3. stroke and jig frequency are regulated difficulty.
Summary of the invention
The purpose of the utility model provides a kind of reducing crown sheave blue elephant; Adopt double-crank connecting rod, double diameter-changeable crown sheave structure, cancelled walking beam, carry out lifting by driving belt; System effectiveness is high, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
The described reducing crown sheave of the utility model blue elephant comprises belt lace, connecting rod, crank counterbalance, crank, reduction box, driving belt, drive motors, base, tie-strut, polished rod eye, frame, big belt, reducing crown sheave.Said crank is installed on the output shaft of reduction box, and crank counterbalance is installed on the crank, and the other end of crank is connected with connecting rod, belt lace one end in order; The other end of belt lace is installed on the small radius wheel of reducing crown sheave, and big belt one end is installed on the long radius wheel of reducing crown sheave, and the other end is connected with polished rod eye; Frame is installed on the base; The reducing crown sheave is installed on the frame top, and tie-strut one end is connected with upper rack, and the other end is connected with base; Reduction box, drive motors are installed on the base, and driving belt is installed on reduction box and the drive motors.
Wherein, said crank, connecting rod, belt lace are two, are installed on successively respectively on the small radius wheel of reduction box and reducing crown sheave.The position of said crank counterbalance can be adjusted along the guide rail on the crank through clamp-screw continuously.Said drive motors drives reduction box through driving belt and drives crank and rotate, crank through connecting rod, belt lace, reducing crown sheave the small radius wheel, big belt, the polished rod eye that drives the reducing crown sheave drives sucker rod and does and pump.The length of said tie-strut can be regulated through regulating leading screw, through the length of adjustable support bar, makes the frame layback, abdicates job position, need not employ the equipment moving frame, and workover treatment is convenient, efficient.
Compared with present technology the utility model has the following advantages:
1, through double-crank connecting rod structure, drive belt and realize switching-over, cancelled walking beam, simplify transmission system, thereby improve system effectiveness;
2, adopt double diameter-changeable crown sheave structure, realize increasing journey through big small radius wheel, energy-saving effect is remarkable;
3, through the length of adjustable support bar, make the frame layback, abdicate job position, need not employ the equipment moving frame, workover treatment is convenient, efficient.
Description of drawings
Fig. 1 is a kind of example structure sketch map of the utility model.
