Abstract
The invention relates to a pumping unit, in particular to a dual-chain drive pumping unit. The pumping unit comprises reverse wheels, balancing weights, chain wheels, chains, bolt cam follower needle roller bearings, a pumping rod, a reverse frame and steel wire ropes. The steel wire ropes are laid on the reverse wheels, one end of each steel wire rope is connected with the reverse frame, and the other end of each steel wire rope is connected with the balancing weight. The lower surface of the reverse frame is connected with the pumping rod. Bearing parts of the bolt cam follower needle roller bearings make contact with the reverse frame, and bolts of the bolt cam follower needle roller bearing are fixedly connected to hinge pins of the chains. The chains cover the two upper chain wheels and the two lower chain wheels, a U-shaped groove is formed in the reverse frame, a guide rail is arranged in the groove, the bolt cam follower needle roller bearings can roll on the guide rail, the two lower chain wheels are connected with an electromotor through a chain transmission device. The dual-chain drive pumping unit is large in stroke and load, high in pumping efficiency, small in reverse impact, and high in adaptability, and the reverse frame is long in service life.
Description
Technical field
The present invention relates to a kind of oil pumper, particularly a kind of chain oil pumper.
Background technology
For a long time, the beam pumping unit that China's oil field development mainly adopts, although beam pumping unit is sturdy durable, its operational efficiency is low, energy consumption is large, can not adapt to the demand of " saving energy and reduce the cost " development.And be difficult to realize long stroke and large load in China and conventional type oil pumper, therefore in the urgent need to a kind of chain oil pumper with advantages such as long stroke, large load, efficiency are high, strong adaptabilities, but the stress point at the specific links place of common double chain type oil pump and sucker rod be not in a plane, this just makes reversing gear bracket in commutation process, have very large shearing, oil pumper reversing impact is large, has affected the life-span of reversing gear bracket.
Summary of the invention
The present invention is intended to address the above problem, and a kind of chain oil pumper is provided, and its stroke is long, and load is large, and oil pumper reversing impact is little, and pumping efficiency is high, and the reversing gear bracket life-span is long, strong adaptability, and its technical scheme adopting is as follows:
A kind of chain oil pumper comprises: reverse wheel, balancing weight, sprocket wheel, chain, bolt outer ring and roll assembly, sucker rod, reversing gear bracket and wire rope, wire rope is layered on reverse wheel, one end of wire rope reversing gear bracket of ining succession, the other end balancing weight of ining succession, the soffit of described reversing gear bracket is connected with sucker rod, the bearing portions of bolt outer ring and roll assembly contacts with reversing gear bracket, and the bolt of described bolt outer ring and roll assembly is fixed on the bearing pin of chain, and chain covers on upper and lower two sprocket wheels.
On the basis of technique scheme, described reversing gear bracket has U-shaped groove, is provided with guide rail in groove, and bolt outer ring and roll assembly can roll on guide rail.
On the basis of technique scheme, the sprocket wheel below described two is connected with motor by chain gearing.
Tool of the present invention has the following advantages: have the stroke of overlength, load is large, and oil pumper reversing impact is little, and the reversing gear bracket life-span is long.

Symbol description
1. reverse wheel, 2. balancing weight, 3. sprocket wheel, 4. chain, 5. bolt outer ring and roll assembly, 6. sucker rod, 7. reversing gear bracket, 8. wire rope.
The specific embodiment
Below in conjunction with accompanying drawing and example, the invention will be further described:
As depicted in figs. 1 and 2, a kind of chain oil pumper of the present invention comprises: reverse wheel 1, balancing weight 2, sprocket wheel 3, chain 4, bolt outer ring and roll assembly 5, sucker rod 6, reversing gear bracket 7 and wire rope 8, wire rope 8 is layered on reverse wheel 1, one end of wire rope 8 reversing gear bracket 7 of ining succession, the other end balancing weight 2 of ining succession, the soffit of described reversing gear bracket 7 is connected with sucker rod 6, the bearing portions of bolt outer ring and roll assembly 5 contacts with reversing gear bracket 7, the bolt of described bolt outer ring and roll assembly 5 is fixed on the bearing pin of chain 4, and chain 4 covers on upper and lower two sprocket wheels 3.
Preferably, described reversing gear bracket 7 has U-shaped groove, is provided with guide rail in groove, and bolt outer ring and roll assembly 5 can roll on guide rail.
Preferably, the sprocket wheel 3 below described two is connected with motor by chain gearing.
Its operating principle is, after actuating motor, motor by chain gearing by transmission of power to two sprocket wheel 3 below, and then drive chain 4 to rotate, bolt outer ring and roll assembly 5 is also with chain 4 motions, while moving to the circular arc portion of chain 4, bolt outer ring and roll assembly 5 continues motion with chain 4 on one side, on the U-shaped groove guide rail of reversing gear bracket 7, slide on one side, realize the change of reversing gear bracket 7 directions of motion, due to 5 two lateral movements to the left and right simultaneously of two bolt outer ring and roll assemblies, sucker rod 6 is all the time on the perpendicular bisector of the stress point in two bolt outer ring and roll assemblies 5, make the impact force of its commutation process smaller, when bolt outer ring and roll assembly 5 moves to the straight line portion of chain 4, start again to drive reversing gear bracket 7 to do rectilinear motion, because reversing gear bracket 7 and sucker rod 6 are affixed, then realized the oil pumping process of sucker rod 6.
With way of example, describe the present invention above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
