Abstract
The utility model relates to a lifting chain adjustment balance weight beam structure and belongs to the technical field of oil pumping machines of an oil extraction machine. According to the technical scheme, the lifting chain adjustment balance weight beam structure comprises a balance weight beam (6), a balance weight block (4), a roller (5), a driving chain wheel (2), a driven chain wheel (7) and a lifting chain (3), wherein the balance weight block is arranged on the balance weight beam by virtue of the roller, the driving chain wheel and the driven chain wheel are respectively arranged at the two ends of the balance weight beam, the lifting chain is respectively connected with the two ends of the balance weight block to form a lifting chain loop, the lifting chain loop is matched on the driving chain wheel and the driven chain wheel, and the driving chain wheel is connected with a turbine worm reducer (1). The lifting chain adjustment balance weight beam structure has the advantages and beneficial effects that the lifting chain adjusts the balance weight beam, the defect that the corrosion can be caused easily in lead screw transmission is overcome, the problem of adjusting the balance of an oil pumping machine in field operation is solved, an oil pumping machine accident is reduced, and the operation of a walking beam balanced oil pumping machine is reasonable.
Description
Technical field
The utility model relates to a kind of hoisting chain and adjusts the counterweight girder construction, belongs to oil recovery machiner oil pumper technical field.
Background technology
There are many oil recovery machiners in each oil field, and wherein a kind of is the common beam balanced oil extractor, and balance mode is beam balance, when adjusting balance, the balance that balancing weight is regulated oil pumper at the mobile diverse location of walking beam, lead screw transmission is all adopted in the movement of balancing weight, because leading screw is exposed to the outside, after oil pumper uses a period of time, corrosion will take place in leading screw and nut, and nut will tighten leading screw, and leading screw can't be rotated, cause leading screw and nut to be scrapped, influence counterweight and the operate as normal of oil pumper.
The utility model content
The utility model purpose provides hoisting chain and adjusts the counterweight girder construction, break the normal procedure and come the mechanism of self-balanced upper rotary to arrange with leading screw, nut transmission, move forward and backward with tension balancing weight before and after the hoisting chain, set up drive sprocket at the two ends of hoisting chain and by movable sprocket, drive sprocket is installed the turbine and worm reducer and is replaced cycloidal reducer, because hoisting chain adapts to wild environment, can use in the open for a long time, overcome the shortcoming of leading screw, nut transmission, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: hoisting chain is adjusted the counterweight girder construction, comprise counterweight beam, balancing weight, roller, drive sprocket, by movable sprocket and hoisting chain, balancing weight is arranged on the counterweight beam by roller, the two ends of counterweight beam arrange drive sprocket respectively and by movable sprocket, hoisting chain is connected to the balancing weight two ends, constitute the hoisting chain ring, the hoisting chain ring mates at drive sprocket with on by movable sprocket.
Described drive sprocket is connected with the turbine and worm reducer, and power drives drive sprocket by the turbine and worm reducer and rotates, and drives the motion of hoisting chain ring, makes balancing weight in the mobile balance of adjusting oil pumper of counterweight beam.
Described balancing weight, the fixedly connected lifting chain bar in two ends, the two ends of hoisting chain connect drive sprocket and by movable sprocket, when drive sprocket rotates, drive balancing weight move left and right on the counterweight beam, adjust the balance of oil pumper;
This practical hoisting chain both can bear the pulling force of lifting, can guarantee that balancing weight is mobile at the counterweight beam by the drive sprocket transmission again; This practical drive sprocket is driven by the turbine and worm reducer, can realize underspeeding, improving moment of torsion and guarantee the balancing weight self-locking, namely guarantee when any position that balancing weight rests on the counterweight beam motionless.
Advantage of the present utility model and effect: hoisting chain is adjusted the counterweight beam, overcome the shortcoming of the easy corrosion of lead screw transmission, solved the difficult problem of oil pumper field work adjustment balance of well pumping unit, reduced the generation of oil pumper accident, made beam-balanced pumping unit work more reasonable.
Description of drawings
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: 1, turbine and worm reducer; 2, drive sprocket; 3, hoisting chain; 4, balancing weight; 5, roller; 6, counterweight beam; 7, by movable sprocket.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Hoisting chain is adjusted the counterweight girder construction, comprise counterweight beam 6, balancing weight 4, roller 5, drive sprocket 2, by movable sprocket 7 and hoisting chain 3, balancing weight is arranged on the counterweight beam by roller, the two ends of counterweight beam arrange drive sprocket respectively and by movable sprocket, hoisting chain is connected to the balancing weight two ends, constitute the hoisting chain ring, the hoisting chain ring mates at drive sprocket with on by movable sprocket.
Described drive sprocket is connected with turbine and worm reducer 1, and power drives drive sprocket by the turbine and worm reducer and rotates, and drives the motion of hoisting chain ring, makes balancing weight in the mobile balance of adjusting oil pumper of counterweight beam.
Driving drive sprocket 2 when turbine and worm reducer 1 rotates rotates, drive sprocket 2 rotates by hoisting chain 3, by movable sprocket 7 pulling balancing weights 4 move left and right, roller 5 is arranged on the balancing weight, guarantee that balancing weight 4 rolls at the counterweight beam, the diverse location of balancing weight 4 on counterweight beam 6 comes balanced oil extractor.
Hoisting chain 2 both can bear the pulling force of lifting, can particularly be worked under the environment in the open air by the drive sprocket transmission again, can guarantee that under mal-condition balancing weight 47 moves diverse location on the counterweight beam, made the operate as normal of oil pumper not be subjected to the influence of environment.
Claims (2)
1. a hoisting chain is adjusted the counterweight girder construction, it is characterized in that: comprise counterweight beam (6), balancing weight (4), roller (5), drive sprocket (2), by movable sprocket (7) and hoisting chain (3), balancing weight is arranged on the counterweight beam by roller, the two ends of counterweight beam arrange drive sprocket respectively and by movable sprocket, hoisting chain is connected to the balancing weight two ends, constitute the hoisting chain ring, the hoisting chain ring mates at drive sprocket with on by movable sprocket.
