Abstract
The utility model relates to a jackscrew bolt for a pumping unit electrical machine. The jackscrew bolt has a structure that an upper lug boss is over a lower lug boss, a screw is over the upper lug boss, the lower lug boss is larger than the upper lug boss, and the screw is provided with male threads. The jackscrew bolt has the advantages that because of being of oval structures and having no edge, the upper lug boss and the lower lug boss cannot be stuck when moving in a slot of a slide of the electrical machine, and the electrical machine is time and labor saving in installation and movement, thereby having remarkable economic benefits.
Description
Technical field
The utility model belongs to the ground installation that oil field machinery oil is used, and is the fixing motor bolt, particularly a kind of motor top thread of oil-pumping machine bolt on the pumping unit.
Background technique
In oil pumping in oil fields, drive sucker rod, oil well pump with the oil extraction by pumping unit, essential mounted motor on the pumping unit, motor is bolted on the base by jackscrew.Present motor jackscrew bolt is the inverted T shape bolt, rail type inverted T shape bolt is lower, plain nut is upper, because the inverted T shape structural edge has corner angle, easily being stuck when moving in the motor slide rail groove irremovable phenomenon occurs, gives to install and mobile motor is made troubles and difficulty, and installation and mobile motor are wasted time and energy, the oil well off-time is long, reduces oil well output.
Summary of the invention
The purpose of this utility model provides a kind of motor top thread of oil-pumping machine bolt, is not stuck when moving in the motor slide rail groove, and installation and mobile motor are time saving and energy saving.
The purpose of this utility model is achieved in that on the lower convex it is upper convex, is screw rod on the upper convex, and lower convex has male thread greater than upper convex on the screw rod, and upper convex is ellipsoidal structure, and lower convex is ellipsoidal structure.
The beneficial effects of the utility model are: upper convex is ellipsoidal structure, and lower convex is ellipsoidal structure, does not have corner angle, can not be stuck when moving in the motor slide rail groove, installation and mobile motor are time saving and energy saving, therefore, the utility model can reach purpose of design, has significant economic benefit.
Description of drawings
Fig. 1 is the utility model embodiment's plan view.
Fig. 2 is the utility model embodiment's plan view.
Fig. 3 is the utility model embodiment's right elevation.
Embodiment
Describe below in conjunction with Fig. 1,2,3 couples of the utility model embodiments.
As seen from the figure, be upper convex 2 on the convex 3 under the utility model, be screw rod 1 on the upper convex 2, lower convex 3 has male thread greater than upper convex 2 on the screw rod 1, and upper convex 2 is ellipsoidal structure, and lower convex 3 is ellipsoidal structure.The effect of lower convex 3 be gear on the lower end surface of motor slide rail, make it can fastening motor, the width of upper convex 2 can be laid in the motor slide rail groove less than the motor slide rail groove, makes it when fastening nut, the utility model can not rotate.
