A kind of long stroke beam-pumping unit with chain without sliding beam belongs to the oil exploitation production equipment.Machine shape size of the present invention is little, and is highly low, and gross weight is 18 tons, and overall height is 9 meters; Travel prolongation mechanism adopts chain drive, functional reliability and durability height; The suspension point commutation is by crank-link mechanism traction sliding block tractive changement, and the commutation acceleration is little, and it is reliable to operate steadily.Its suspending point loading is 12 tons, and length of stroke is 6 meters, and jig frequency is 2.5~6.5 meters/minute, is not only applicable to the oil exploitation of general oil well, more is applicable to high sticking, rich gas, many sand, heavy wax, water logging and deep mining or powerful exploitation.It is simple in structure, and advanced technology is repaiied easily well and made.

Description

The present invention is a kind of no walking beam, has the long stroke pumping unit of chain travel prolongation mechanism, belongs to the oil exploitation production equipment.
At present, the domestic nothing oil beam type long stroke pumping unit that uses in oilfield exploitation has the above oil pumper of steel cable pitch increased type long stroke pumping unit of CN86102979 path chain formula oil pumper and CN85103185 to exist various deficiencies respectively.Many as path chain formula oil pumper consumable accessory, functional reliability and poor durability, commutation specific links, cylinder balancing sealing etc. are consumable accessory, and path chain produces than high acceleration at last bottom dead centre, and the suspension point commutation owes steady.Steel cable pitch increased type long stroke pumping unit, fatigue failure takes place in the increment steel cable because of bend radius is little, application life is short, eccentric wear and curved card take place in the balance weight guide rail under the tractive moment loading of the public fast line of increment slide rail set, appearance and size height, weight are big, especially a day wheel diameter reaches 4.5 meters, shows top-heavy, and resistance to overturning is poor.Above-mentioned oil pumper is subjected to the influence of casing or height all to exist maintenance and repair inconvenience, regulates the problem of stroke and jig frequency trouble.
The object of the present invention is to provide a kind of long stroke beam-pumping unit with chain without sliding beam, overcome the deficiency of existing long-stroke pumping unit without walking beam, for oil exploitation provides simple in structure, advanced technology is made the new pumping unit of easily repairing well.Complete machine overall dimensions of the present invention are little, highly low, gross weight is 18 tons, and overall height is 9 meters.Travel prolongation mechanism adopts chain drive, functional reliability and durability height; The suspension point commutation realizes that by crank-link mechanism traction sliding block tractive changement the commutation acceleration is little, and it is reliable to operate steadily; Adopt outstanding rope chain balance sysmte, the heavy and polished rod of the direct hanging balancing in outstanding rope chain two ends, wherein balance weight does not support the formula that sinks for having, and balance weight sinks in underground, work safety.Complete machine is low to the field work environmental requirement, and this oil pumper does not have consumable accessory, no guard shield, and adjusting stroke, jig frequency are all carried out on ground, and operating maintenance is convenient.
Moving-mass of the present invention is little, thereby inertia loading is little, and energy loss is low.Since low 2.5 times/minute~6.5 times/minute of strokes per minute, greatly 12 tons of suspending point loadings, and point suspension movement speed is low to be 15 meters/minute~39 meters/minute, makes the suction of pump be full of the raising pump efficiency.Because stroke is long, is 6 meters, loss of plunger stroke is little relatively, and the pumping liquid measure is big.It is not only applicable to the oil exploitation of general oil well, more is applicable to high sticking, rich gas, many sand, heavy wax, water logging and deep-well oil exploitation or powerful exploitation.Its functional performance is wide, under identical polished rod load, can realize long stroke, and big discharge capacity or dark pump are hung; Under identical discharge capacity, can realize dark pump extension or small pump diameter, little load; Under identical pump setting depth, can realize the operating characteristic of big pump diameter, long stroke, big discharge capacity.
Primary structure of the present invention has: support, frame; Motor, V belt, pulley concial disk, reduction box; The slide block draw-off mechanism comprises: crank-link mechanism, slide block, slide rail, reversing chain, the sprocket wheel that commutates up and down; Travel prolongation mechanism comprises: increase the journey sprocket wheel, increase the journey chain, the sprocket-type head sheave; Outstanding rope chain type balance sysmte comprises: outstanding rope chain, balance weight, guiding third wheel, suspension point etc.
Accompanying drawing is the structural representation of long stroke beam-pumping unit with chain without sliding beam.
Elaborate below in conjunction with accompanying drawing: support " 24 " links to each other with frame " 23 ", and other structure of oil pumper is installed in respectively on support " 24 " and the frame " 23 ".Motor " 1 " links to each other with reduction box " 3 " by V belt " 2 " pulley concial disk " 25 "; Crank " 4 " is housed on the reduction gearbox output shaft; One end of crank " 4 " links to each other with connecting rod " 5 " and constitutes crank-link mechanism; Slide block " 7 " in the slide rail " 22 " links to each other with the end of reversing chain " 8 " with connecting rod " 5 "; Reversing chain " 8 " is bearing on commutation sprocket wheel " 6 ", " 9 "; By crank-link mechanism rotatablely moving of motor " 1 " is converted to slide block " 7 " and the vertical linear reciprocating motion of reversing chain " 8 " in slide rail " 22 ".Commutation sprocket wheel " 9 " with increase journey sprocket wheel " 10 " with being loaded on the sprocket shaft " 20 "; Increase journey sprocket wheel " 14 " and be loaded on sprocket shaft " 21 " together with sprocket-type head sheave " 15 "; Increase journey sprocket wheel " 10 " and increase journey sprocket wheel " 14 " and link to each other by increasing journey chain " 12 ".By commutation sprocket wheel " 9 " with increase journey sprocket wheel " 10 ", the pitch diameter that increases journey sprocket wheel " 14 " and sprocket-type head sheave " 15 " is formed the chain travel prolongation mechanism by bigger than 2~4 multiplications surely, it makes the stroke of slide block obtain amplifying.The sprocket wheel of travel prolongation mechanism counterclockwise back and forth rotates along suitable around sprocket shaft when work.Outstanding rope chain " 13 " by sprocket-type head sheave " 15 ", guiding third wheel " 16 " and directly lodge on the gear teeth of sprocket-type head sheave " 15 " upper limb and guiding third wheel " 16 " upper limb, one end of outstanding rope chain is consolidated in suspension point " 11 " and connects the extension polished rod, and the other end directly hangs the formula balance weight " 17 " that sinks.
Embodiment: the present invention drops into and recovers the oil when producing, and complete machine is placed on the basis, sets up stroke, jig frequency; Make slide block " 7 " and reversing chain " 8 " in the crank-link mechanism tractive slide rail " 22 " carry out up-and-down movement, amplify by the stroke of travel prolongation mechanism slide block " 7 ", and make sprocket-type head sheave " 15 " along back and forth rotating along counter clockwise direction, thereby make outstanding rope chain " 13 " on sprocket-type head sheave " 15 " and guiding third wheel " 16 ", move back and forth transmission power, the balance weight " 17 " and the suspension point " 11 " at outstanding simultaneously rope chain " 13 " two ends are gone up fixed polished rod in the up-and-down movement of frame both sides, finally realize long stroke pumping fluid by outstanding reciprocating motion of restricting chain " 13 ".With the radius that changes crank " 4 ", regulate rotating speed or replacing triangle belt leather wheel " 25 " that jig frequency can change motor " 1 " when regulating stroke.
