Description
Technical field: the utility model 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, and, with the commutation of Frequency Converter Control magneto, running part is belt or chain.2, haulage cable is fixed on the horse head of oil pumper, and the other end connects output roller.3, haulage cable 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 purpose of this utility model is to overcome the shortcoming of 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, haulage cable pulls horse head by movable pulley, 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 utility model by motor, coupling device,
load-bearing wires rope, haulage cable, the composition such as reversing speed reducer, pylon, walking beam, two horse heads with assembly pulley, directive wheel, spring take-up, spring vibration damper.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.The haulage cable being connected on output roller is drawn from cylinder, and by movable pulley, directive wheel, regulating wheel, pull horse head to swing up and down, the load-bearing wires rope on horse head does straight reciprocating motion.Output
it is also feasible that the haulage cable of drawing on cylinder only walks around that movable pulley is directly connected with damping spring and drives horse head to move up and down.When output roller clockwise rotates, be wound around right side haulage cable and loosen left side haulage cable 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
or on base, and with the translation-angle that swings up and down of pumping unit horsehead.
Because output roller 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 directive wheel, regulating wheel be set,
the damping spring being hinged in frame also can play tension.while rotating counterclockwise, situation is identical.
The movable pulley of two horse head belows 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 utility model 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), movable 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: with detailed description of the invention, the utility model is further described by reference to the accompanying drawings.
Fig. 1 is complete machine schematic diagram of the present utility model;
Fig. 2 is layout schematic diagram of the present utility model.
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 1 of balance-type type assembly pulley oil pumper, have two horse heads on the walking beam 2 of pylon 1 top, i.e. the first horse head 3 and the second horse head 4.On the first horse head 3
carryingwire rope 14 passes through polished rod eye connecting with pumping rod, and bears polished rod load; On the second horse head 4
carryingwire rope 17 is born ballast box load;
load-bearing wires rope (14), (17) are identical with the operating mode of conventional pumping unit.Outputon cylinder 11, draw two
tractionwire rope 15,16 is not born load, is only responsible for two horse heads of traction.Haulage cable 15 is drawn from cylinder 11, walk around regulating wheel 10, directive wheel 12,
movingpulley 5 connects with the damping spring 7 of pylon 1 below; Haulage cable 16 is drawn from cylinder 11, walk around regulating wheel 9, directive wheel 13,
movingpulley 6 connects with the damping spring 8 of pylon 1 below.
tractionit is also feasible that wire rope 15,16 directly walks around that movable pulley 5,6 is connected with damping spring 7,8.
In floor map shown in Fig. 2, reversing speed reducer 18 is arranged in right side, also can be arranged in left side.
the concrete structure separate case application of reversing speed reducer patent, repeat no more.
In accompanying drawing shown in Fig. 3, increase by a joint articulated link chain 19 in the bottom of the first horse head 3, movable pulley 5 is arranged on articulated link chain 19.Movable pulley 5 can also be installed the middle part 7 of horse head or the position on top 8.The second horse head 4 is identical with the first horse head 3 structures.
The utility model, 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 running block is housed on pumping unit horsehead all drop on protection domain of the present utility model.
