Abstract
The utility model relates to a novel chain pumping unit without a reversing frame, which belongs to the improvement of oil exploitation machines in oil engineering. The utility model is mainly composed of a drive sprocket, a driven sprocket, a track chain, a special connecting rod and a special chain section. The seesaw motion along both sides of the sprockets of the special chain section is changed into the seesaw motion along the centerlines of the sprockets by the connecting rod, so the complicated reversing frame widely used in the present chain pumping unit is canceled. Meanwhile, the pneumatic counterbalance of the present chain pumping unit is changed into weight balance.
Description
The utility model relates to a kind of chain type oil pump of novel no reversing gear bracket, and it is the improvement that belongs to the oil recovery machiner in the petroleum works.It is made of drive sprocket, driven sprocket, path chain and special connecting rod and specific links, and the swing of the connecting rod that is connected with balancer weight by specific links realizes pumping of well head suspending weight.
In petroleum industry, the oil recovery machiner that is adopted in the oil field development is diversified, wherein chain type oil pump uses widely, its advantage is that floor space is little, complete machine is in light weight, be subjected to the welcome at industrial and mineral scene deeply, but its gentle dynamic balancer of mechanical commutation mechanism is but very complicated, and easily breaks down.
The purpose of this utility model provides a kind of chain type oil pump of novel no reversing gear bracket with regard to being to avoid above-mentioned the deficiencies in the prior art part, it both can save complicated changement, the air-balance of complexity can be changed into balancer weight simple in structure again.It mainly is to be made of drive sprocket, driven sprocket, path chain, connecting rod, balancer weight and tow rope, its major technology characteristics are that an end of connecting rod links to each other with path chain with specific links, the other end then is connected with the balancer weight hinge that is arranged between fixed guide, and the running orbit of balancer weight is arranged on the center line of drive sprocket and driven sprocket.
Accompanying drawing is structural representation of the present utility model.
The drawing of accompanying drawing is described as follows:
1---drive sprocket 2---driven sprocket 3---path chain 4---specific links
5---connecting rod 6---balancer weight 7---tow rope 8---head sheave
9---well head suspending weight 10---fixed guide
In order to realize better above-mentioned purpose of the present utility model, designer of the present utility model is fixed on an end of pull rope (7) on the balance weight (6), and the other end is then walked around head sheave (8) and linked to each other with well head suspending weight (9).
Come enumeration structural feature of the present utility model below in conjunction with drawings and Examples:
In actual design with in making, artificer of the present utility model is arranged on counterweight block in the fixed guide, and its reciprocating direction is consistent with the center line of drive sprocket and driven sprocket; Its path chain is around drive sprocket and driven sprocket shuttling movement, and connects connecting rod with specific links, and the other end of connecting rod then is hinged on the balancer weight; An its tow rope then end is connected on the balancer weight, and the other end is walked around head sheave and is connected on the well head suspending weight.Like this, drive drive sprocket, driven sprocket and path chain motion by the rotating speed on request of the power after slowing down, the connecting rod that specific links connected on the path chain is motion together thereupon also.The motion of path chain makes the specific links that connects connecting rod pump at the right and left, and the other end of connecting rod and balancer weight are hinged, the relative swing of its connecting rod then converts tow rope and balancer weight to along the to-and-fro motion up and down of two centre of sprocket lines, the other end of tow rope is then walked around head sheave and is connected the well head suspending weight, thereby realizes the oil pumping function.
Characteristics of the present utility model be by connecting rod with being transformed into along the pumping of centre of sprocket line of specific links along pumping of sprocket wheel both sides, thereby cancelled present chain type oil pump the baroque reversing gear bracket that extensively adopts; Simultaneously, also change the air-balance of present chain type oil pump into the pouring weight balance.
The utility model is owing to saved baroque reversing gear bracket and pneumatic counterbalance system, manufacturing and maintenance expenses had both been saved, reduced cost of production again, and made the reliability of pumping unit work improve greatly, therefore popularizing application prospect has widely been arranged in petroleum development engineering.
Claims (2)
1, the chain type oil pump of no reversing gear bracket, it mainly is by drive sprocket (1), driven sprocket (2), path chain (3), connecting rod (5), balancer weight (6) and tow rope (7) constitute, an end that it is characterized in that connecting rod links to each other with path chain (3) with specific links (4), the other end then is connected with balancer weight (6) hinge that is arranged between fixed guide (10), and the running orbit of balancer weight (6) is arranged on the center line of drive sprocket (1) and driven sprocket (2).
2, the chain type oil pump of no reversing gear bracket according to claim 1 is characterized in that an end of tow rope (7) is fixed on the balancer weight (6), and the other end is then walked around head sheave (8) and linked to each other with well head suspending weight (9).
