Abstract
The utility model discloses an oil-pumping machine with stroke length increased by gears. The oil-pumping machine adopts a stand type support stand, and a hoisting sheave is arranged on a machine frame, and the hoisting sheave and an increasing stroke length gear wheel are installed on a same shaft. The utility model is characterized in that a four bars reverse mechanism is composed of a crank, a connecting rod, a crossbeam, and a sector gear. The crossbeam is hinged with the sector gear, and the hinge point is designed at the eccentric position in the sector gear plane. The sector gear is positioned in the vicinity of the hoisting sheave, and the sector gear is directly engaged with the increasing stroke length gear wheel. The oil-pumping machine replaces a chain transmission reverse and increasing stroke length mechanism in prior art so that the structure of the oil-pumping machine is simpler. The utility model has the advantages of high reliability and convenient maintenance, and wearing parts are less.
Description
The utility model be a kind of be the long stroke pumping unit of stroke length increasing of feature with the gear drive, it is the ground installation in the mechanical oil production technology equipment.
Long stroke pumping unit, changement and the travel prolongation mechanism of producing both at home and abroad all adopts chain or wire rope transmission, increases journey at present.As Chinese patent CN85 103185, CN86102979, stroke is long though this class oil pumper has, suspending point loading is big, the absorption efficiency height of pump, be beneficial to the characteristics such as exploitation of viscous crude and deep-well, but chain in changement or the travel prolongation mechanism or wire rope rapid wear in actual production, perishable, become the weak link in the oil pumper parts.
The purpose of this utility model is to provide a kind of gear long stroke pumping unit of stroke length increasing that replaces chain or wire rope transmission, this oil pumper changes the chain drive in the prior art into gear drive, the changement of oil pumper constitutes four-bar mechanism by crank, connecting rod, crossbeam and gear, crossbeam and gear adopt and are articulated and connected, and pin joint is arranged on the eccentric position in the gear plane; Increase journey gear and head sheave coaxial rotation, gear is arranged near the head sheave, and directly and increase the journey gears engaged.Gear generally adopts sector gear, and this can alleviate the weight and volume of complete machine.The power drive system of this oil pumper is identical with prior art with balance sysmte.
Accompanying drawing is a gear long stroke pumping unit of stroke length increasing structural representation.
Do to describe in detail below in conjunction with accompanying drawing: complete machine adopts vertical structure, head sheave 9 is equipped with at the top of frame 14, increase journey gear 8 and head sheave 9 coaxial rotation, the pitch diameter that increases journey gear 8 is in proportion less than the pitch diameter of head sheave 9, sector gear 7 is housed near the head sheave, sector gear 7 meshes with increasing journey gear 8, and the pitch diameter of sector gear 7 is in proportion less than the pitch diameter that increases journey gear 8.Fan type gear 7 constitutes four bar changements with crossbeam 6, connecting rod 5, crank 4, and crossbeam 6 adopts with sector gear 7 and is articulated and connected, and the pin joint design is at the eccentric position place of sector gear inner plane; Crank 4 is installed on the power drive system 1, and power drive system 1 is housed on the base 15, and outstanding rope 10,12 hangs on head sheave 9 left and right sides respectively, the fixed polished rod eye 11 in outstanding rope 10 lower ends, outstanding rope 12 lower ends suspention balance weight 13.
Oil pumper at first is that power drive system 1 drives crank 4 rotations in the course of the work, and by connecting rod 5, crossbeam 6, it is reciprocating to drive sector gear 7.This moves through to mesh to pass to and increases journey gear 8, increase journey gear 8 and head sheave 9 coaxial rotation, head sheave 9 drives outstanding rope 10,12 and does straight reciprocating motion up and down, owing to increase journey gear 8 and the coaxial installation of head sheave, both rotational angular velocities equate, but the pitch diameter of head sheave 9 is greater than the pitch diameter that increases journey gear 8, both rotate arc length and do not wait, and head sheave 9 pitch diameters are big, and arc of rotation is grown up, the reciprocating stroke of four-bar mechanism is also scaled up, thereby realize that oil pumper increases journey.
The utility model is simple in structure, and moving-mass is little, and inertia loading is little, and energy consumes little, and length of stroke is big, and the drawing liquid amount is big, and reliability height, durability height are suitable for the oil extractions such as heavy oil wells, watered-out well, deep-well.
Claims (2)
1, a kind of employing Vertical Rack, head sheave is housed on the frame, head sheave with increase the coaxial installation of journey gear, changement adopts the gear long stroke pumping unit of stroke length increasing of four-bar mechanism, it is characterized in that four bar changements are to be made of crank, connecting rod, crossbeam and sector gear, crossbeam 6 is articulated and connected with sector gear 7, pin joint design eccentric position place in the sector gear plane; Sector gear is positioned near the head sheave, and directly with increase journey gear 8 and mesh.
2, gear long stroke pumping unit of stroke length increasing according to claim 1, the pitch diameter that it is characterized in that sector gear 7 is in proportion greater than the pitch diameter that increases journey gear 8.
