Description

A kind of intelligent oil pumping machine of twin-well operation
Technical field
The invention belongs to field of petroleum machinery, more particularly, to a kind of intelligent oil pumping machine of twin-well operation.
Background technology
For most Cong Jing formula oil recovery block, oil well quantity is more, if accordingly an oil pumper is joined using a bite well, Cause equipment investment more like that, the waste of steel and electronic component, therefore it is directed to a fairly large number of block of oil well, domestic a lot Producer also develops the oil pumper of multiple twin-well formulas, thus can reduce equipment purchase cost and also save material simultaneously.
Although there being prior art to realize twin-well operation, and tens kinds of patents of invention are announced, for example:Middle promulgated by the State Council Bright patent(The patent No.:201310182571.7, patent name:Tower-type list twin-well adjustable support arm and balance-adjustable oil pumping Machine), Chinese invention patent(The patent No. 200710300314.3, patent name:Rotary foundation support arm crank bidirectional balancing double-well is taken out Oil machine), Chinese invention patent(The patent No.:201110121154.2, patent name:Energy saving twin-well eoil and using method)With Chinese invention patent(The patent No.:200910036665.7, patent name:A kind of double-well sharing oil pumping machine)All disclosing one kind can Realize the oil pumper of twin-well operation, but technique scheme there is also a lot of deficiencies, pass through to rotate whole pumping unit including 1. Realize individual well operation, poor operability for 180 °;2., substantially using reduction box, fail largely cost-effective;3. suitable Situation about being more or less the same for twin-well load, the larger operating mode of inapplicable two mouthfuls of well load difference, limit to range;Though 4. So enable individual well operation(Another mouthful of well is repaired or is stopped operation), but the pulling force that cannot realize individual well load with counterweight is put down Weighing apparatus, causes motor overload it has to use more powerful motor, cost advantage is inconspicuous;Although equipment component equipped with Counterweight, but cannot manifest and pick up by oneself counterweight, inconvenience need to be operated by crane.
Content of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of structure is simple, low cost and expiring The intelligent oil pumping machine of the twin-well operation of sufficient various working.
In order to realize above-mentioned purpose, present invention employs following technical scheme:
A kind of intelligent oil pumping machine of twin-well operation, including the pylon on the basis of being fixedly mounted on, the first reducing wheel group, second Reducing wheel group, elevator wheel, big belt wheel, motor and Combined balance weight block;The left and right two ends of the top platform of described pylon are cut with scissors respectively It is connected to the first leading arm and the second leading arm, the outside of the first leading arm and the second leading arm is separately installed with the first guide wheel and Two guide wheels, described first reducing wheel group and the second reducing wheel group are separately fixed at the first leading arm and the inner side of the second leading arm, Described elevator wheel and big belt wheel rotate coaxially setting, and are fixed on the central authorities of tower top platform, and described motor is fixed on greatly Between belt wheel and the second reducing wheel group, and motor is connected by belt with big belt wheel, and the bull wheel of described elevator wheel passes through first Deceleration pull rope is connected with the bull wheel of the first reducing wheel group, and the steamboat of described elevator wheel passes through the second deceleration pull rope and second The bull wheel of reducing wheel group is connected, and the steamboat of the first reducing wheel group is connected with one end of the first pull rope, the first pull rope another One end is bypassed the first guide wheel and is connected with the first polished rod eye, and the steamboat of the second reducing wheel group is connected with one end of the second pull rope, The other end of the second pull rope is bypassed the second guide wheel and is connected with the second polished rod eye, and the top platform of described pylon is further fixed on Control chamber, the lower end central authorities of the top platform of described pylon are further fixed on the first counterweight directive wheel and the second counterweight directive wheel, institute State the bottom that Combined balance weight block is located at pylon central authorities.
Preferably:The upper end of the top platform of described pylon is additionally provided with protective cover.The protective cover one being adopted Formula designs, and had both protected upper mounting plate part to prevent sunlight direct irradiation, and can prevent rainwater again.
Preferably:The width of described pylon two end portions is the half of the width of pylon mid portion.Due to two While being provided with leading arm, load can be preferably born in the reduction of pylon width, and intermediate width increases and internally can place configuration, and this Structural soundness is good, can bear the oil pumping draw-bar pull compared with big load and Cross Wind Force load.
The present invention having the beneficial effects that compared with prior art:1st, due to using special reducing wheel group, not slowing down Case etc., therefore whole machine transmission efficiency is compared existing product and is improved more than 5%, really realizes high performance-price ratio;
2nd, 180 ° of whole equipment need not be rotated, only standby balancing weight Fast Installation need to be can achieve that any individual well continues Operation;
3rd, in addition leading arm vernier device and well head can be passed through according to the arbitrarily devised tower length of twin-well actual range Distance;
4th, balancing weight is combination type, be respectively suitable for twin-well load differ greatly, the operating mode such as individual well operation, carry out the essence of pulling force Really balance is it is ensured that motor operation is in optimum state, simultaneously also energy-conservation to a greater extent;
5th, due to not having gearbox structure to compare existing twin-well oil-pumping machine cost savings more than 25%, because the present invention is automatically controlled And the double-well sharing such as steel construction is a set of, therefore compares 2 equipment assembly instincts of individual well oil pumper and save more than 50%.
