Description
Affiliated technical field:
The utility model relates to a kind of oil field equipment, and particularly the linear oil pumping machine well head is from stepping down device.
Background technology:
Linear oil pumping machine is when underground work, working vehicle lifts by crane sucker rod up and down, need certain operating space, require oil pumper to get out of the way the certain distance of well head like this, the essential characteristic of linear oil pumping machine is to have abandoned traditional quadric chain principle, is provided with a pylon, devices such as directive wheel, cylinder, reducer, motor are housed on the pylon, by the rotating of controller control motor, or with the rotating of mechanical mode index drum, thus the moving up and down of realization polished rod eye.The tradition beam pumping unit be the side by horse head change or on turn over and realize stepping down; At present, the linear oil pumping machine kind is a lot, and the mode of stepping down is various, and what have is provided with cantilever at frame top, and directive wheel is installed on the cantilever, seesaws by leading screw drive cantilever and realizes stepping down; What have installs slideway on base, drive complete machine with the dedicated hydraulic device and move forward and backward, and above-mentioned dual mode cost is very high, is unfavorable for the popularization of product, also has unsafe factor.
The utility model content:
The utility model purpose provides a kind of linear oil pumping machine well head from stepping down device, helps applying, and handling safety solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the linear oil pumping machine well head comprises pylon, driving mechanism, cylinder, belt, polished rod eye, pull rope, fixed pulley, Connection Block from the device of stepping down, driving mechanism is connected with cylinder, be arranged on tower top, the well head belt is connected with pull rope by polished rod eye, and pull rope changes after the direction with Connection Block on the pylon by fixed pulley and is connected.
Said driving mechanism comprises motor, reductor, shaft coupling, and motor, reductor, cylinder connect successively by shaft coupling.
Said fixed pulley quantity is two at least, is separately positioned on the both sides, front and back of pylon, and one is fixed pulley before the pylon, and one is fixed pulley behind the pylon.
Reset for the ease of pylon, also be provided with the Connection Block that resets.
Use the utility model, unloading earlier, then ballast box is fallen on the base, unloaded weight belt, then the pylon stone bolt is pulled down, equipment is pushed up dried up mud basis with accent top fastening bolt or jack, roller is installed, and equipment moves by the slip Variable roll like this, reduces frictional resistance, then pull rope is passed before the pylon fixed pulley behind the fixed pulley and pylon, be connected with Connection Block, at this moment, the crawl motor, make belt up, by the transmission of power, produce an active force backward, when this active force during greater than frictional force, entire equipment just begins to move backward, realizes the purpose of stepping down; When oil pumper will be returned original position, pull down being connected of pull rope and Connection Block, pull rope directly is connected with the Connection Block that resets, like this, when the crawl motor, when belt is moved upward, equipment is subjected to one and said process opposite effect power, and equipment is moved forward, and pylon is got back to correct position.
The beneficial effects of the utility model are: in the whole operation process, all be the power that utilizes equipment itself, and all be to operate down below, climb up platform without the operator, make operation safer, more laborsaving, on the other hand, need not use special technological equipment, reduced manufacturing cost, easy to utilize.
Description of drawings:
Accompanying drawing is the utility model example structure schematic diagram.
Among the figure: fixed pulley 13 behind fixed pulley 10, base 11, Connection Block 12, the pylon before the motor 1, pylon 2, reducer 3, cylinder 5, directive wheel 6, belt 7, polished rod eye 8, pull rope 9, pylon, Connection Block 14 resets.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
With reference to accompanying drawing, the linear oil pumping machine well head comprises pylon 2, driving mechanism, cylinder 5, belt 6, polished rod eye 8, pull rope 9, fixed pulley, Connection Block 12 from the device of stepping down, driving mechanism is connected with cylinder, be arranged on tower top, the well head belt is connected with pull rope by polished rod eye, and pull rope changes after the direction with Connection Block on the pylon by fixed pulley and is connected.Driving mechanism comprises motor 1, reductor 3, shaft coupling, and motor, reductor, cylinder connect successively by shaft coupling.Fixed pulley quantity is two, is separately positioned on the both sides, front and back of pylon, and one is that 10, one on fixed pulley is a fixed pulley 13 behind the pylon before the pylon.Reset for the ease of pylon, also be provided with the Connection Block 14 that resets.
The course of work: motor 1 links to each other with reducer 3 by shaft coupling, reducer 3 links to each other with cylinder 5 by shaft coupling, be tied with belt 7 on the cylinder, belt 7 lower ends are connected to polished rod eye, during oil pumper work, polished rod eye 8 links to each other with polished rod, by the rotating of motor, realize moving up and down of oil-extractor polish-rod, thereby realize the suction of crude oil.When the oil pumper operation, polished rod eye 8 is laid down PRL, ballast box is fallen on the base 11, unloads ballast box, like this, the center of gravity of oil pumper is toward moving down, make complete machine more stable, then Connection Block 12 is linked to each other with polished rod eye 8 usefulness pull ropes, the centre has through fixed pulley 13 behind fixed pulley 10 before the pylon and the pylon, the stone bolt of base 11 is unloaded, with jackscrew or jack base is pushed up dried up mud basis, put down roller, become sliding friction when complete machine is moved and be rolling friction, reduce friction, at this moment crawl motor, under the driving of motor, belt moves upward, transport to backward thereby drive oil pumper, and the distance that moves is very long.In the time will making the oil pumper return, pull rope is unloaded from Connection Block 12, be directly connected to the Connection Block 14 that resets, crawl motor, belt drive pull rope resets oil pumper.
