The present invention relates to a tower type oil pumping machine which belongs to an oil production machine. The present invention provides a tower type oil pumping machine which has the advantages of simple structure and small occupation area. The present invention comprises a base seat (4) and has the essential structure that the bottom end of a screw rod (18) in an oil storing body (14) on the upper part of the base seat (4) is provided with a pull rod (1) and a contact plate (10) which can be in contact with an upper stroke switch (12) and a lower stroke switch (7), the screw rod (18) is engaged with a screw nut (19) in an electric machine box (22) on the upper part of the oil storing body (14), the screw nut (19) is fixed in the center of a rotor (20) of a motor (23), a guide block (17) which is corresponding to the screw rod (18) and a guide groove (16) is arranged below the electric machine box (22), and a wire rope (25) on the upper end of the screw rod (18) is connected with a balancing weight box body (26) by a pulley (27) on a support frame (24).
Description
Technical field:
The present invention belongs to oil recovery machiner.
Background technology:
The primary structure of existing oil pumper normally motor links to each other with an end of lever by gearbox, connecting lever, and the wire rope of the other end of lever is arranged with sucker rod.When motor rotated, it is constantly reciprocating that sucker rod drives piston, and underground crude oil is extracted on the ground.But there is following shortcoming in existing oil pumper: the component volumes such as connecting lever that constitute oil pumper are all bigger, and therefore, floor space is big; In addition, complex structure, installation and maintenance are difficulty relatively.
Summary of the invention:
The present invention is exactly at the problems referred to above, and a kind of simple in structure, tower-type pumping unit that floor space is little is provided.
The present invention adopts following technical scheme: the present invention includes base, its structural feature is that the bottom of the oil storage cylindrical shell inner screw of base top is provided with touch panel, the pull bar that can touch upper stroke switch, lower stroke switch, screw rod is meshed with the nut in the motor case of oil storage cylindrical shell top, nut is fixed on the rotor center of motor, the below of motor case is provided with the corresponding guide pad of threaded guide groove, and the cotton rope of the upper end of screw rod links to each other by the pulley homostasis loaded van body on the support.
Beneficial effect of the present invention:
1. simple in structure, volume is little:
Main member of the present invention is to be center and dependency structure with the screw rod, and it is simple in structure, member is few, and volume is little, floor space is little, and complete machine is vertical layout, and compact conformation is reasonable;
2. the life-span is long:
Screw rod of the present invention comes and goes in oil storage is simplified all the time, make the contact surface of screw rod, nut have lubrication oil all the time, has reduced the wearing and tearing of screw rod, nut, has increased the application life of this machine;
3. be easy to installation and maintenance:
Because member of the present invention is few, simple in structure, therefore made things convenient for installation, maintenance.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
The present invention includes base 4, the bottom of oil storage cylindrical shell 14 inner screws 18 of base 4 tops is provided with touch panel 10, the pull bar 1 that can touch upper stroke switch 12, lower stroke switch 7, screw rod 18 is meshed with the nut 19 in the motor case 22 of oil storage cylindrical shell 14 tops, nut 19 is fixed in the rotor 20 of motor 23 in the heart, the below of motor case 22 is provided with threaded 18 guide grooves, 16 corresponding guide pads 17, and the cotton rope 25 of the upper end of screw rod 18 links to each other by the 27 homostasis loaded van bodies 26 of the pulley on the support 24.
Be provided with upper mounted plate 15, bottom plate 5 in oil storage cylindrical shell 14, the portable plate 11 of the spring 13 of upper mounted plate 15 is provided with upper stroke switch 12, and the portable plate 8 of the spring 6 of bottom plate 5 is provided with lower stroke switch 7.
Nut 19 can be fixed on the rotor 20 of motor 23 by key 21.
Also can be provided with and adjust window 9, can be convenient to adjust the position of upper stroke switch 12, lower stroke switch 7 etc. by this in the side of oil storage cylindrical shell 14.
Bottom pull bar 1 in oil storage simplified 14 is outside equipped with the seal receptacle 2 with sealing mat 3.
Below in conjunction with course of action of description of drawings:
At first, oil storage cylindrical shell 14 contains lubrication oil; Pull bar 1 links to each other with underground oil guide pipe inner carrier; Be filled with in the balance weight casing 26 with pull bar 1, the corresponding weight of piston weight.Starter motor 23, nut 19 rotates, and screw rod 18 moves downward under the qualification of guide groove 16, guide pad 17; Meanwhile, the pull bar 1 of screw rod 18 bottoms promotes piston downwards, and balance weight casing 26 affects screw rod 18 servo-actuateds by cotton rope 25; Motor 23 reverses, and nut 19 reverse thereupon, and screw rod 18 moves upward under guide groove 16, guide pad 17 qualifications, and the pull bar 1 of screw rod 18 bottoms moves upward thereupon, underground crude oil thereupon piston move upward, on the referred ground.
