Abstract
The utility model relates to a horizontal double-chain pulley guide long constant-speed balancing oil pumping machine. The horizontal double-chain pulley guide long constant-speed balancing oil pumping machine mainly comprises an oil pumping rod, a guide pulley, two sprockets, transmission chains, a transmission steel rope, a motor and a balancing block and is characterized in that the motor is in fit transmission with the sprockets; the two sprockets are horizontally arranged; the transmission chains are horizontally arranged; the transmission steel rope is fixed with the transmission chains; one end of the transmission steel rope is connected with the oil pumping rod and the other end of the transmission steel rope is connected with the balancing block; and the transmission steel rope and the guide pulley coordinate to control the transmission direction. The horizontal double-chain pulley guide long constant-speed balancing oil pumping machine has reasonable structural design. The height of the oil pumping machine is reduced through the transmission chains arranged horizontally. The transmission steel rope is directly in fixed fit with the transmission chains, a steering mechanism is not required, the motor rotates in one way, and the steering aim is fulfilled according to different transmission directions of upper and lower chains. Under the control of the guide pulley, the oil pumping rod and the transmission chains are not on the same axial line, so that the oil pumping rod is convenient to take out and the oil well is convenient to maintain.
Description
Technical field
The utility model relates to oil pumper, and is particularly a kind of through 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 big, 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 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 through the chain-drive oil pumper that application number is that 01139505.2 one Chinese patent application discloses, and the chain of this oil pumper vertically is provided with, and between chain and steel cable, is provided with the conversion that changement realizes that sucker rod moves up and down.This structure has following shortcoming:
1, the changement part is many, and structure is complicated, and unbalance stress in the running, is prone to cause mechanism's operation jam, switching-over dumb, causes system stable low, has reduced mechanism reliability and system effectiveness;
2, because the oil pumper impulse stroke is longer usually, adopt vertical chain structure to make mechanism height higher, bring many unfavorable factors: (a) mechanism height is too high, and the system center of gravity of making 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, to the operation of oil well rig, safeguard and will cause bigger influence.
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.
The utility model content
The purpose of the utility model is to provide 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 utility model institute pumping unit designed mainly is made up of 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 through cooperating transmission; And two pairs of sprocket wheels are horizontally disposed with; Driving chain also is horizontally disposed with, and the transmission wirerope is fixed on a certain joint of driving chain, and 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 property, economical with materials is convenient to installation and maintenance;
In order to improve the reliability that is fixedly connected between transmission wirerope and the driving chain; Described driving chain is two driving chains that laterally arrange; Described transmission wirerope is arranged between two driving chains, and through wirerope clamping device and driving chain matching and fixing.Described clamping device both sides are provided with bearing pin and cooperate with two driving chains, and the centre is a wirerope clamping device fixed conveyor wirerope.Do the simple harmonic motion except that 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 through the direct secure fit of wirerope clamping device simultaneously, have simplified mechanism structure, improve the efficient and the operational reliability of system.
Said equilibrate counterweight is connected with sucker rod through wirerope, and its weight scalable is 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, through the real-time regulated oil pumper motion of 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 utility model, reasonable in design is through 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 switching-over 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.
