Abstract
The invention discloses a horizontal dual-chain pulley guide long constant speed balanced pumping unit, which mainly comprises a sucker rod, a guide pulley, two chain wheels, a transmission chain, a transmission steel rope, a motor and a balance block, and is characterized in that the motor is in matched transmission with the chain wheels; the two chain wheels are horizontally arranged; the transmission chain is horizontally arranged; the transmission steel rope and the transmission chain are fixed together; one end of the transmission steel rope is connected with the sucker rod, and the other end of the transmission steel rope is connected with the balance block; and the transmission steel rope and the guide pulley are matched to control the transmission direction. The horizontal dual-chain pulley guide long constant speed balanced pumping unit is reasonable in structural design, and according to the transmission chain which is horizontally arranged, the height of the pumping unit is reduced. The transmission steel rope and the transmission chain are directly and fixedly matched, a reversing mechanism is not required, the motor rotates in a unidirectional mode, and the reversing aim is fulfilled by utilizing different transmission directions of the upper and lower chains; and moreover, due to the control of the guide pulley, the sucker rod and the transmission chain are not on the same axis, the sucker rod is conveniently taken out, and an oil well is maintained.
Description
Technical field
The present invention relates to oil pumper, particularly a kind of by the long at the uniform velocity balance oil extractor of the horizontal double chain pulley guiding of chain-drive.
Background technology
More in view of existing conventional pumping unit well system transmission link, system effectiveness is low, and energy consumption is large, and utilization rate of equipment and installations is low, causes being prone to the problem of " low load with strong power "; Simultaneously, conventional pumping unit need to be according to the circulation of finishing the work of certain mechanical rule, and ground and bottom equipment are difficult to reach rational coordination, and machine, bar, pump accident are more.
It is a kind of by the chain-drive oil pumper that application number is that 01139505.2 Chinese patent application discloses, and the chain of this oil pumper vertically arranges, and is provided with the conversion that changement realizes that sucker rod moves up and down between chain and steel cable.This structure has following shortcoming:
1, the changement part is many, and structure is complicated, and unbalance stress in the running, easily causes mechanism's operation jam, commutation dumb, causes system run all right low, has reduced mechanism reliability and system effectiveness;
2, because the oil pumper impulse stroke is usually longer, adopt the vertical chain structure so that mechanism height is higher, bring many unfavorable factors: (a) mechanism height is too high, so that system gravity increases stability of a system variation; (b) for guarantee mechanism stability and sound construction reliable, certainly will increase material and mechanism's weight; (c) mechanism height is too high, is unfavorable for the work such as installation, operation, maintenance of mechanism;
3, the vertical setting places chain-wheel mechanism directly over the oil well, on the operation of oil well rig, safeguard and will cause larger impact.
For overcoming above-mentioned shortcoming, fully absorb and use for reference the advanced technology of similar products at home and abroad, the long at the uniform velocity balance oil extractor scheme of the horizontal double chain pulley guiding of brand-new design on the basis of traditional oil pumper.
Summary of the invention
The objective of the invention is provides a kind of transmission efficiency high, simple in structure for the deficiency that solves above-mentioned technology, moves the long at the uniform velocity balance oil extractor of horizontal double chain pulley guiding controlled, easy to maintenance.
In order to achieve the above object, the oil pumper that the present invention is designed, mainly consisted of by leading block, pair of sprocket, driving chain, transmission wirerope, wirerope clamping device, prime mover and equilibrate counterweight, it is characterized in that described prime mover and sprocket wheel are by cooperating transmission, and two pairs of sprocket wheels are horizontally disposed with, driving chain also is horizontally disposed with, the transmission wirerope is fixed on a certain joint of driving chain, transmission wirerope one end connects well rod, the other end connects equilibrate counterweight, and the transmission wirerope cooperates the control transmission direction with leading block.The characteristics of this transmission mechanism are dexterously by the characteristics of chain drive its biserial to be horizontally disposed with, and adopt the horizontal type structure pattern, are installed in ground, and length of stroke only equates with transmission mechanism runner spacing and runner diameter, very easily realizes long stroke design; Can significantly reduce simultaneously the level height of oil pumper, improve mechanism stable, economical with materials is convenient to installation and maintenance;
In order to improve the reliability that is fixedly connected with between transmission wirerope and the driving chain, described driving chain is two driving chains that be arranged in parallel, described transmission wirerope is arranged between two driving chains, and is fixed by wirerope clamping device and driving chain.Described clamping device both sides are provided with bearing pin and cooperate with two driving chains, and the centre is wirerope clamping device fixed conveyor wirerope.Do the simple harmonic motion except the reciprocating reversing short-term in mechanism's running, all the other 80% above times are all made uniform motion and wirerope, leading block is stressed good, and load capacity is strong.Transmission wirerope and driving chain need not changement by the direct secure fit of wirerope clamping device simultaneously, have simplified mechanism structure, improve efficient and the operational reliability of system.
Described equilibrate counterweight is connected with sucker rod by wirerope, its weight can be regulated, be complementary with concrete oil well condition, prime mover task driven moment in running is basic identical, can be according to the shaft bottom actual condition, regulate in real time the oil pumper motion by control system, the running status of coupling ground and bottom equipment reduces machine, bar, pump accident rate to greatest extent, improves the result of use of system, running efficiency of system is high, the product obvious energy conservation.
The long at the uniform velocity balance oil extractor of the resulting horizontal double chain pulley guiding of the present invention, reasonable in design is by the height of horizontally disposed driving chain reduction oil pumper.The direct secure fit of transmission wirerope and driving chain need not changement, prime mover one-directional rotation, and the transmission direction difference of lower chain reaches the commutation purpose in the utilization, and is simple in structure, easy to maintenance.On the other hand because, the control of reason leading block, sucker rod and rotating link chain not on same axis, operation, the maintenance of convenient taking-up well recovery equipment.
