Abstract
The utility model relates to a nested combined type belt wheel for oil pumping machines, which is used for conveniently regulating the stroke frequency of an oil pumping machine. The belt wheel is composed of belt wheels (2) which are provided with large diameters and are mutually nested and combined together, belt wheels (1) with small diameters, and scallop-shaped fixing plate (3) and connecting bolts (4) which are used for connection and fixation. The utility model with the advantages of novel structure, reasonable design and safety can be utilized to flexibly and conveniently regulate the working stroke frequency of an oil pumping machine with time and labor saved and is favorable to raising the work efficiency and the producing time effect of oil wells.
Description
The utility model relates to a kind of mechanical device that pumping well is produced, particularly a kind of motor of oil extractor belt pulley of being convenient to adjust the pumping unit jig frequency of being used for.
In pumping production technology, according to the characteristics of structure of oil well, grade of oil and the variation of fluid supply capacity, often need to adjust the jig frequency of pumping unit, so that oil well is produced, realize stable and high yields under optimum Working.The method of the change pumping unit jig frequency that mining site adopts usually has two kinds, and a kind of is the motor of changing different rotating speeds, and another kind is a belt pulley of changing different-diameter on the motor reel again.The method that changes motor speed is implemented relatively difficulty, and this is because of motor price comparison height, and the installation dimension of motor is also incomplete same, so adopt this method fewer.Change the both economical practicality of method of motor pulley, so adopt this method at present basically.But this method is relatively required great effort in practical operation, and very trouble need to adopt special tool and number people to cooperate, and it is time-consuming longer to change institute, influences oil well production.
The purpose of this utility model be to provide a kind of simple in structure, cost is lower, adjust the conveniently box-like belt of oil pumping machine wheel of nested groups of jig frequency.
The utility model is to realize like this.The box-like belt of oil pumping machine of the nested groups that the utility model provides is taken turns by the mutually nested large and small diameter pulley of combining and is connected and fixed and forms with fan-shaped fixed plate and attachment bolt.Internal layer small diameter pulleys right-hand member is provided with 4 boss that are uniformly distributed along the circumference, and endoporus cooperates with motor reel, and keyway is arranged, and is connected and fixed with key and motor; Outer major diameter belt pulley is sleeved on outside the small belt pulley, and its inner headed face right-hand member is provided with 4 symmetrical grooves that match with small diameter pulleys right-hand member boss; Be respectively equipped with symmetrically on the large and small belt pulley left side two overlap each other, shape, the on all four scalloped recess of size, respectively be provided with 4 screws in the groove, big two shared fan-shaped fixed plates with holes of small belt pulley are placed in the groove, and tighten with bolt.During installation, the major diameter belt pulley is sleeved on the small diameter pulleys outside, 4 scalloped recess of bull wheel right-hand member are enclosed within on 4 fan-shaped boss of steamboat right-hand member (that is the fan-shaped boss on the steamboat is inlaid in the scalloped recess on the bull wheel), put into fan-shaped fixed plate, penetrate attachment bolt in the screw respectively and tighten and get final product.When adopting small belt pulley, back out bolt, outer big belt pulley is unloaded, can realize that pumping unit works at a slow speed with little jig frequency this moment; When needs improve the pumping unit jig frequency, outer major diameter belt pulley loaded onto get final product.Because box-like belt pulley one end of this kind nested groups adopts fan-shaped fixed plate to connect, the dismounting of large and small belt pulley only need turn attachment bolt, and is very convenient; The other end adopts fan-shaped boss and groove embedding mutually, then can strengthen the whole tightness that connects therebetween, guarantees the steady proper functioning of pumping unit.
The utility model novel structure, reasonable in design, safe and reliable, utilize it can adjust pumping unit work jig frequency flexible, time saving and energy savingly, help increasing work efficiency and the oil well production timeliness, be suitable for and apply.
Fig. 1 is a structural representation of the present utility model.
Fig. 2, Fig. 3 are its left and right view.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of internal layer small diameter pulleys 1, outer major diameter belt pulley 2, fan-shaped fixed plate 3, attachment bolt 4, wherein, small diameter pulleys 1 endoporus has keyway, adopt key to be connected and fixed with motor, the periphery right-hand member is uniformly distributed with 4 fan-shaped boss along the circumference, and the left side is arranged with 2 scalloped recess, is evenly equipped with 4 screws in the groove.Major diameter belt pulley 2 endoporus and small diameter pulleys 2 external diameters are Spielpassung, its right-hand member inner headed face is provided with 4 scalloped recess that match with the fan-shaped boss of steamboat, the left side is provided with 2 and the corresponding symmetrical scalloped recess of steamboat scalloped recess, uniform 4 screws in the groove.Be evenly equipped with 4 circular holes on the fan-shaped fixed plate 3, be used to penetrate bolt interior foreign steamer is connected and fixed.
