Description
Technical field:
The utility model relates to a kind of oil pumper protective device, especially pumping-unit motor adjustment screw mandrel protective device.
Background technology:
In field of oil field oil extraction, oil pumper is important ground lifting equipment.Oil pumper is using motor as power source, and motor is rotated by belt drive decelerator, and decelerator drives walking beam to swing up and down by double leval jib and realizes lifting object.Conveniently belt replacing and adjustment, motor cabinet is arranged with motor adjusting device.And existing motor adjusting device is subject to the etch corrosions such as wind and rain, the problem that during adjustment, base easily reverses and offsets because reasons in structure exists, when causing adjustment, screw mandrel rust stubbornly refuses to rotate, and loses adjustment function, is unfavorable for applying.
Utility model content:
The etch corrosions such as wind and rain are subject to, the problem that during adjustment, base easily reverses and offsets in order to solve existing motor adjusting device.The utility model provides a kind of pumping-unit motor to adjust screw mandrel protective device.This pumping-unit motor adjustment screw mandrel protective device has long service life, adjusts easily laborsaving, the stable feature of base.
The technical solution of the utility model is: this pumping-unit motor adjustment screw mandrel protective device comprises oil pumping unit base, motor base, bearing pedestal, screw mandrel and screw.Bolt on motor base is placed in the strip hole on oil pumping unit base, limited location block under bolt is also connected on bolt by nut, bearing pedestal is bolted on oil pumping unit base, screw is welded on motor base, screw left part is connected with screw mandrel casing, sealing ring is had between screw and screw mandrel casing, lubricating oil is filled with in screw mandrel casing, retractable bellows chamber cylinder is connected with between screw and bearing pedestal, lubricating oil is filled with in bellows chamber cylinder, screw mandrel left part to be connected with screw by screw thread and to be placed in screw mandrel casing, screw mandrel right part to be connected with bearing pedestal by bearing and to be placed in bellows chamber cylinder.
The utility model has following beneficial effect: this pumping-unit motor adjustment screw mandrel protective device is placed in the strip hole on oil pumping unit base owing to adopting the bolt on motor base, limited location block under bolt is also connected on bolt by nut, bearing pedestal is bolted on oil pumping unit base, screw is welded on motor base, screw left part is connected with screw mandrel casing, sealing ring is had between screw and screw mandrel casing, lubricating oil is filled with in screw mandrel casing, retractable bellows chamber cylinder is connected with between screw and bearing pedestal, lubricating oil is filled with in bellows chamber cylinder, screw mandrel left part to be connected with screw by screw thread and to be placed in screw mandrel casing, screw mandrel right part to be connected with bearing pedestal by bearing and to be placed in the structure in bellows chamber cylinder.Utilize screw mandrel casing and bellows chamber cylinder and interior lubricating oil thereof effectively to protect screw mandrel, screw mandrel is not got rusty by etches such as wind and rain, and can lubricate screw mandrel.When utilizing guide vane end stop effectively can eliminate adjustment, base reverses and the phenomenon of skew, and finally increase the service life, easily laborsaving during adjustment, adjustment steadily.This pumping-unit motor adjustment screw mandrel protective device has long service life thus, adjusts easily laborsaving, the stable feature of base.
Accompanying drawing illustrates:
Accompanying drawing 1 is the utility model structural representation.
1-oil pumping unit base in figure, 2-motor base, 3-bearing pedestal, 4-screw mandrel, 5-screw, 6-screw mandrel casing, 7-bellows chamber cylinder, 8-guide vane end stop.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this pumping-unit motor adjustment screw mandrel protective device comprises oil pumping unit base 1, motor base 2, bearing pedestal 3, screw mandrel 4 and screw 5.Motor base 2 is on oil pumping unit base 1, bolt is through the strip hole on motor base 2 and oil pumping unit base 1, bolt is trapped upper limit position block 8, be connected on bolt by nut again, because guide vane end stop 8 area is large, thus eliminate when motor base 2 adjusts and produce torsion and shift phenomenon, make adjustment easily laborsaving, base is steady.Bearing pedestal 3 is bolted on oil pumping unit base 1; screw 5 is welded on motor base 2; screw 5 left part is connected with screw mandrel casing 6; screw mandrel 4 is placed in screw mandrel casing 6, has sealing ring between screw 5 and screw mandrel casing 6, is filled with lubricating oil in screw mandrel casing 6; screw mandrel 4 is protected not get rusty by etches such as wind and rain by screw mandrel casing 6 and lubricating oil; increase the service life, make adjustment easily laborsaving by oil lubrication screw mandrel 4, base is steady simultaneously.Retractable bellows chamber cylinder 7 is connected with between screw 5 and bearing pedestal 3; bellows chamber cylinder 7 one end is connected with screw 5; the other end is connected with bearing pedestal 3; screw mandrel 4 is placed in bellows chamber cylinder 7; be filled with lubricating oil in bellows chamber cylinder 7, protect screw mandrel 4 not get rusty by etches such as wind and rain by bellows chamber cylinder 7 and lubricating oil, increase the service life; make adjustment easily laborsaving by oil lubrication screw mandrel 4, base is steady simultaneously.Screw mandrel 4 left part is connected with screw 5 by screw thread, and screw mandrel 4 right part is connected with bearing pedestal 3 by bearing.
