Abstract
The utility model patent relates to presss from both sides film oil pumper damping reversing arrangement described in a kind of novel four chain pumping unit damping reversing arrangements and drives chain to obtain linear reciprocating motion by sprocket wheel, described chain is connected oil pumper damping reversing arrangement by crank throw with pin, described sprocket wheel and chain are connected with a joggle, crank throw and crossbeam are rotationally connected, bearing is embedded in crossbeam two ends, pin installs and is connected to crossbeam two ends, described reversing arrangement is by connecting counterweight connecting rod above nut, described reversing arrangement is by connecting with pumping rod below nut.Overcome traditional reversing arrangement unstable, the shortcomings such as bearing load is little, have structure simple, supporting capacity is strong, and good stability, has the advantages such as damping performance.The stacking spring used in the utility model patent has higher elasticity and toughness, can adapt to the oil recovery environment of various complexity.
Description
Technical field
The utility model relates to a kind of chain type oil pump reversing arrangement, belongs to mechanical design field.
Background technology
Since the nineties in 20th century, east China main oilfield enters middle high water-cut development period in succession, for guaranteeing to produce, presenting be badly in need of adopting long stroke pumping unit, to increase the Liquid output of oil well to the requirement of oil pumper.It is simple that chain type oil pump has structure, the features such as stroke is long, and gearratio is accurate, but chain drive is large in peak value commutation position acceleration change, and inertial load is large.
Utility model content
The utility model, for the problems referred to above, provides a kind of novel four chain pumping unit damping reversing arrangements and overcomes original oil pumper commutation position acceleration greatly, the defect of the large fragile oil rig of inertial load.
The technical solution adopted in the utility model is as follows:
A kind of novel four chain pumping unit damping reversing arrangements comprise sprocket wheel 1, chain 2, crank throw 3, crossbeam 4, bearing 5, pin 6, damping device shell 7, stacking spring 8, spring 9, nut 10, sucker rod 11, counterweight connecting rod 12, described oil pumper damping reversing arrangement drives chain 2 to obtain linear reciprocating motion by sprocket wheel 1, described chain 2 is connected oil pumper damping reversing arrangement by crank throw 2 with pin 6, described sprocket wheel 1 is connected with a joggle with chain 2, crank throw 3 and crossbeam 4 are rotationally connected, bearing 5 is embedded in crossbeam 4 two ends, pin 6 installs and is connected to crossbeam 4 two ends, described reversing arrangement is by connecting counterweight connecting rod 12 above nut 10, described reversing arrangement is by connecting with pumping rod 11 below nut 10.
Above-mentioned damping reversing arrangement comprises crossbeam 4, bearing 5, crank throw 3 and damping device and forms, and crossbeam is connected with crank throw by bearing, and motion is passed to crossbeam by crank throw, and damping device shell is connected with crossbeam by sucker rod, counterweight connecting rod, nut.
Above-mentioned damping reversing arrangement is formed by stacking by the stacking spring of damping device shell and damping device inside, adds a spring in inside simultaneously.
The utility model tool has the following advantages:
(1) crank throw of special construction can be connected with two of a chain node, and considerably increasing can bearing load power.
(2) by bearing, crank throw is connected with crossbeam, can reduce due to during chain drive with shearing, will be slidably connected changing into rolls connects simultaneously, can reduce frictional force, strengthen and application life of part realize energy-conservation simultaneously.
(3) at the damping device that crossbeam and sucker rod and counterweight connecting rod coupling part are set up, can effectively alleviate because chain drive is produced acceleration to highs and lows, and the vibrations caused by external environment.

Symbol description
1. sprocket wheel, 2. chain, 3. crank throw, 4. crossbeam, 5. bearing, 6. sell, 7. damping device shell, 8. stacking spring, 9. spring, 10. nut, 11. sucker rods, 12. counterweight connecting rods.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As Figure 1-3, a kind of novel four chain pumping unit damping reversing arrangements comprise sprocket wheel 1, chain 2, crank throw 3, crossbeam 4, bearing 5, pin 6, damping device shell 7, stacking spring 8, spring 9, nut 10, sucker rod 11, counterweight connecting rod 12, described oil pumper damping reversing arrangement drives chain 2 to obtain linear reciprocating motion by sprocket wheel 1, described chain 2 is connected oil pumper damping reversing arrangement by crank throw 2 with pin 6, described sprocket wheel and chain are connected with a joggle, crank throw and crossbeam are rotationally connected, bearing is embedded in crossbeam two ends, pin installs and is connected to crossbeam two ends, described reversing arrangement is by connecting counterweight connecting rod 12 above nut 10, described reversing arrangement is by connecting with pumping rod 11 below nut 10.Described damping reversing arrangement comprises crossbeam 4, bearing 5, crank throw 3 and damping device and forms, and crossbeam 4 is connected with crank throw 3 by bearing 5, and motion is passed to crossbeam 5 by crank throw 3.Damping device is connected with crossbeam by sucker rod 11, counterweight connecting rod 12, nut 10.Described damping device shell is superimposed upon damper 7 enclosure by stacking spring 8, adds a spring 9 simultaneously form in inside.
Operationally sprocket wheel 1 rotates and drives chain 2 to obtain linear reciprocating motion, with pin 6, chain 2 and crank throw 3 are located, via crank throw 3 and bearing 4, the linear reciprocating motion of chain 2 is passed to crossbeam 4 again, crossbeam 4 is connected counterweight connecting rod 12 by damping device with nut 10 up, crossbeam 4 in below by damping device and nut 10 connecting with pumping rod 11, thus driven the linear reciprocating motion of sucker rod, complete oil recovery process.
Preferably, described damping reversing arrangement is formed by stacking by the stacking spring 8 of damping device shell 7 and damping device inside, adds a spring 9 in inside simultaneously.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
