A crank is arranged on the output shaft of a reduction box, a crank counterweight is arranged on the crank, 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 arranged on a small radius wheel of the reducing crown sheave, one end of the big belt is arranged on a big radius wheel of the reducing crown sheave, the other end of the big belt is connected with the rope hanger, the frame is arranged on the base, the reducing crown sheave is arranged at the top of the frame, one end of the supporting pull rod is connected with the upper part of the frame, the other end of the supporting pull rod is connected with the base, the reduction box and a driving motor are arranged on the base, and a transmission belt is arranged on the reduction box and the driving motor. The oil pumping unit has the characteristics of simplicity in structure, removal of a walking beam, simplification of a transmission system, high system efficiency, remarkable energy-saving effect, no need of moving the frame by equipment, fastness and convenience in well repair operation and the like, and is widely applied in oil extraction engineering of petroleum exploitation engineering.
Description
Technical field
Patent of the present invention 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 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 this invention is to provide 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.
Reducing crown sheave blue elephant of the present invention 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 pull bar, makes the frame layback abdicate job position, and the equipment of need not employing moves frame, and workover treatment is convenient.
Compared with present technology the present invention 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 pull bar, make the frame layback, abdicate job position, the equipment of need not employing moves frame, and workover treatment is efficient and convenient, and efficient is high.
