Abstract
A balance type pulley block pumping unit is composed of a tower, a reversing reduction box, double horse heads with movable pulleys, a guide pulley, a damping spring and the like. The reversing reduction box is in a mechanical reversing mode, and the various defects of a frequency converter-motor reversing mode are overcome. The two horse heads are respectively provided with one movable pulley, the tractive force of the horse heads is reduced by 50%, the power of the motor is lowered by 15%, and the energy-saving effect is obvious. The structural style is the most energy-saving structural style in all beam-pumping units.
Description
Technical field: the present invention relates to oil field machinery oil equipment, especially a kind of balance-type type assembly pulley oil pumper.
Background technology: existing balance type beam-pumping unit (being also two Horse Beam Pumping Units), as the patent No. is: 2013200178467; 2007201275030; 2008101085459 disclosed several balance type beam-pumping units have three large features: 1, adopt motor commutation technology, with the commutation of Frequency Converter Control magneto.2, wire rope is fixed on the horse head of oil pumper, and the other end connects output roller.3, wire rope adopts gravity tensioning mode.
The shortcoming of above-mentioned prior art is: 1, and frequency converter-motor commutation technology is very complicated, poor reliability.Electrical network is not only polluted in the commutation of magneto frequent starting, also makes the permanent magnet in magneto accelerate demagnetization.In addition, magneto price is very expensive.2, directly draw pumping unit horsehead with wire rope, wire rope is suffered that tractive force is larger, causes the stress of horse head unstable.The pendulum angle of horse head is restricted simultaneously, is difficult to obtain maximum stroke.3, wire rope adopts gravity tensioning mode to increase cost, is also inconvenient to adjust.
Goal of the invention: the shortcoming that the object of the invention is to overcome above-mentioned prior art.1, the balance-type type assembly pulley oil pumper of a kind of ' mechanical commutation ' is provided, thoroughly break away from the design philosophy with frequency converter-motor commutation, fundamentally solve the negative effects such as pollution electrical network that frequent starting motor brings.2, change the mode of directly drawing horse head with wire rope, application assembly pulley principle pulls horse head, makes the laborsaving merit of economizing again of operation of oil pumper.(newest research results proves, adopts assembly pulley for the equipment of frequent lifting heavy, not only laborsaving but also economize merit).3, spring vibration damper and spring take-up are set and replace gravity tensioning device, make the operation of oil pumper more steady, energy-conservation more obvious, cost significantly reduces.
Summary of the invention: for achieving the above object, balance-type type assembly pulley oil pumper of the present invention is made up of motor, coupling device, reversing speed reducer, pylon, two horse heads with assembly pulley, directive wheel, spring take-up, spring vibration damper etc.Wherein, ' reversing speed reducer ' I research and develop successfully, and separate case application patent.
When work, the output roller of reversing speed reducer is exported positive and negative torque.Wire rope on cylinder pulls horse head to move up and down by regulating wheel, directive wheel, movable pulley.When cylinder clockwise rotates, be wound around right side wire rope and loosen left side wire rope simultaneously, now left side horse head drives sucker rod up, and right side horse head is descending with ballast box.Above-mentioned reverse movement when cylinder rotates counterclockwise.In order to reduce reversing impact, the wire rope of walking around movable pulley is connected on the damping spring of oil pumper pylon below.Damping spring is hinged in frame, can be with the translation-angle that swings up and down of pumping unit horsehead.
Because cylinder is to do forward and reverse rotation, while clockwise rotating, be wound around right side wire rope and loosen left side wire rope simultaneously, the left side wire rope being relaxed can produce relaxed state, need between cylinder and guide wheel, regulating wheel be set.While rotating counterclockwise, situation is identical.
The movable pulley of horse head below can also be arranged on top or the middle part of horse head.Also can be arranged on a joint articulated link chain.As long as can make horse head obtain larger pivot angle, increase oil pumper stroke, more laborsaving when traction horse head, be exactly the best position of movable pulley.
Beneficial effect: the benefit that the present invention obtains is:
(1), energy-saving effect highly significant.The most energy-conservation form of structure in all beam pumping units.
(2) adopt ' mechanical commutation ' rear motor all the time to a direction uniform rotation, uniform motion is best motion state.It does not need the commutation of motor frequent starting, has solved the problems such as the large pollution electrical network of starting current.Omitted frequency converter, many negative effects of having avoided frequency converter to produce in transformation, conversion process.
(3), assembly pulley is installed on horse head, more laborsaving than direct traction horse head.His efficiency factor=0.94; Pulling force S=0.53Q, it is nearly 1/2 that pulling force reduces, and power of motor reduces 15%.
(4), the wire rope of traction horse head is connected to oil pumper pylon below, and maintenance is adjusted very convenient.
(5) light, the easy adjustment of spring take-up force of gravity tensioning apparatus, cost are low.
Brief description of the drawings: the invention will be further described with detailed description of the invention by reference to the accompanying drawings.
Fig. 1 is complete machine schematic diagram of the present invention;
Fig. 2 is layout schematic diagram of the present invention.
Fig. 3 is that the movable pulley on horse head is arranged on articulated links or the schematic diagram of other position.
Detailed description of the invention: in the complete machine schematic diagram of balance-type type assembly pulley oil pumper, on the walking beam 2 of pylon 1 top, respectively there is a horse head 3 and 4 at two ends.Wire rope 18 on horse head 3 passes through polished rod eye connecting with pumping rod, and bears polished rod load.Wire rope 17 on horse head 4 is born ballast box load.Wire rope 15,16 is not born load, is only responsible for two horse heads of traction.Wire rope 15 is walked around cylinder 11, regulating wheel 10, directive wheel 12, pulley 5 and is connected with the damping spring 7 of pylon 1 lower left; Wire rope 16 is walked around cylinder 11, regulating wheel 9, directive wheel 13, pulley 6 and is connected with the bottom-right damping spring 8 of pylon 1.Because cylinder 11 is to do forward and reverse rotation, while clockwise rotating, be wound around right side wire rope 16, loosen left side wire rope 15 simultaneously, now wire rope 15 performances are lax, need regulating wheel 10, and regulating wheel 10 is connected with extension spring.When cylinder rotates counterclockwise, wire rope 16 is lax, is provided with regulating wheel 9, and structure is identical with 10.
In floor map shown in Fig. 2, reversing speed reducer 18 is arranged in right side, also can be arranged in left side.
In accompanying drawing shown in Fig. 3, pulley 5 is arranged on a joint articulated link chain 19.Can also assembly pulley be set at the middle part of horse head 3 or top.No matter being set, several movable pulley wire rope 15 can only walk around one of them movable pulley.Right side situation is identical.
The present invention, not only for single well production, is more suitable for twin-well and recovers the oil.No matter structurally do any variation, or apply this technology at other field, in every commutation that reversing speed reducer is applied in to oil pumper, and within two Horse Beam Pumping Units that assembly pulley is housed on pumping unit horsehead all drop on protection scope of the present invention.
