Description
Technical field
The present invention relates to oil field equipment, exactly is gantry chain transmission type twin-well oil pumping unit.
Background technology
At present traditional type bar pump (being commonly called as the machine of the kowtowing) oil pumper of oil field oil recovery usefulness can only the individual well operation, the power assembling is big, power consumption is high, power utilization is low, secondly this bar pump oil pumper drives motor and rotates feedback current in electrical network sometimes in descending process, cause the line voltage distribution shakiness, shorten service life of equipment, even damage equipment.In addition, bar pump oil pumper is to utilize belt transmission, and sleety weather is subjected to snow-broth to influence the back belt creep, belt wheel often occurring changes and loses the wheel phenomenon, belt is easily aging under the normal condition, and it is fixed or often change belt rotary speed unstabilization also can to occur, therefore influences problems such as job scheduling and output.
Summary of the invention
At the problems referred to above that prior art exists, the present invention aims to provide a kind of gantry chain transmission type twin-well oil pumping unit that is suitable for twin-well operation simultaneously.
For achieving the above object, the technical solution used in the present invention is:
A kind of gantry chain transmission type twin-well oil pumping unit, mainly by motor, sprocket wheel, chain, portal frame is formed, be furnished with to described portal frame bilateral symmetry upper sprocket wheel, the circulation link chain of lower sprocket is gone up in lower sprocket and connection, the upper sprocket wheel of both sides connects by horizontal universal driving shaft, motor via reducer is in transmission connection with the lower sprocket of a side wherein, the stake body of the portal frame left and right sides is provided with slideway longitudinally, be provided with in the slideway by the relay plate, take off the slide unit that power device and counterweight are formed, the last relay plate of two slide units is connected through wirerope, the corner of portal frame is provided with the leading block that supports wirerope, the following relay plate of two slide units is connected with connector through wirerope, and portal frame is provided with and the corresponding power of the taking off device of two slide units.
The last relay plate of described two slide units is connected through three road wireropes, and the corner of portal frame is provided with three groups of leading blocks that support wirerope.
The following relay plate of described two slide units is connected with connector through the twice wirerope.
Gantry chain transmission type twin-well oil pumping unit of the present invention has changed the oil pumping mode of traditional type bar pump oil pumper, already change twin-well single action masterpiece industry into by individual well single action masterpiece, utilize the interactional cooperation of pump rod self gravitation, power has been applied to ultimate attainment, changed traditional oil pumper in the downward stroke process energy dissipation and to the infringement of installations and facilities, made full use of the self-energy of equipment self, utilize equilibrium principle, lifting weight has been dropped to the limit, extremely heavy pump rod weight can be ignored, its input power is only considered to match than just passable with last liter weight during work, and its coupling power can reduce 3/4ths than traditional oil pumper, and is the motion of twin-well single action power, consider the frictional force factor, though suitably increase proportioning power, also energy-conservation more than 60% than tradition oil pumping mode, reach energy-saving effect.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, this gantry chain transmission type twin-well oil pumping unit is mainly by motor 1, sprocket wheel, chain, portal frame 2 is formed, be furnished with to the bilateral symmetry of portal frame 2 upper sprocket wheel 3, the twice circulation link chain 5 of lower sprocket is gone up in lower sprocket 4 and connection, the upper sprocket wheel 3 of both sides connects by horizontal universal driving shaft 6, motor 1 is in transmission connection by the reductor 7 and the lower sprocket 4 of a side wherein, the stake body of portal frame 2 left and right sides is provided with slideway 8 longitudinally, be provided with in the slideway by the relay plate, take off the slide unit that power device 9 and counterweight 10 are formed, the last relay plate 11 of two slide units is connected through three road wireropes 12, the corner of portal frame 2 is provided with three groups of leading blocks 13 that support wirerope, the following relay plate 14 of two slide units is through twice wirerope 12 ' be connected with connector 15, portal frame be provided with the corresponding power of the taking off device 9 of two slide units '.
This equipment utilization chain drives pump rod and does lifter motion, two wells are connected with flexible connector by portal frame, the operation of realization disjunctor, twin-well is when out of service, equipment is in equilibrium state under the effect of two well pump bar gravity, when in working order, chain drives the upwards operation of A well pump bar, B well pump bar has just lost EQUILIBRIUM CONDITION, and then beginning is descending under the effect of gravity, and after up A well pump bar took off power power, two wells were in of short duration equilibrium state again, at this moment it is up that the opposite side chain begins to drive B well pump bar, another state that disequilibrates, A well pump bar begins descending under the effect of gravity, being equilibrated at when being broken in order of twin-well, realized the even running of the upstream and downstream that two well pump bars replace, thereby crude oil has been sent back to ground.
The present invention is applicable to the twin-well operation simultaneously of close together (in the 2-6M scope), portal frame can carry out distance and stroke adjustment (in the 2-6M scope) according to the requirement of well spacing and pump rod stroke, also can be applicable to the transformation of individual well operation as required, its main technical requirements is exactly the power disengaging of control pump rod top dead centre and the buffering behind the disengaging power, adopt automatic power disengaging mode in the design and flexibly connect buffering method, thereby realized by rotating of the smooth transition of one-way movement mode to vertical break-in motion mode, operate steadily, reduce mechanical wear, prolonged the application life of equipment.This apparatus adaptability is strong, and is practical, and market prospects are preferably arranged.
The present invention is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every have identical with a present invention or akin technical scheme, all within its protection domain.
