Description
Technical field
The utility model is related to a kind of motor support objects, are specifically related to a kind of motor jackscrew with protective device.
Background technology
In oil extraction in oil field production operation, operating personnel usually need by adjust jackscrew to the position of pumping-unit motor into
Row adjustment reuses adjusting jackscrew after fixing motor and withstands motor, and motor adjusts jackscrew due to being chronically exposed to field
In adverse circumstances, screw thread is damaged frequent occurrence, bending, screw thread rust are waited indefinitely phenomenon, causes jackscrew to adjust time-consuming and laborious, not only
The labor intensity for increasing operating personnel, also forms security risk, increases the downtime of pumping unit, influences normally to produce.
Utility model content
The purpose of this utility model is in view of the above technical defects, to provide a kind of motor jackscrew with protective device, is led to
It crosses and protective device is set for leading screw, solve jackscrew and be easy to happen the technical barrier that screw thread rust is dead, bending and screw thread are damaged.
Technical solution：A kind of motor jackscrew with protective device, it includes the jackscrew across baffle, baffle fixed setting
On pedestal, it is characterized in that：Swivel nut is arranged on jackscrew, an end face joining of swivel nut is on baffle, the setting of another end face
Rubber sheet gasket is fixedly installed axis pin in the outer periphery of swivel nut, passes through axis pin that fixed plate is arranged, pass through shaft in the lower part of fixed plate
Counterweight hinge is connected, torsional spring is set in shaft.
Advantageous effect：The utility model effectively can protect jackscrew to be exposed to the sun and rain, and effectively protect jackscrew
Screw thread rust is dead, bending and screw thread are damaged.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the present embodiment.
Specific implementation mode
With reference to attached drawing 1, a kind of motor jackscrew with protective device, it includes the jackscrew 10 across baffle 9, and baffle 9 is solid
It is fixed to be arranged on pedestal 1, it is characterized in that：Swivel nut 5 is arranged on jackscrew 10, an end face joining of swivel nut 5 is on baffle 9, separately
Rubber sheet gasket 4 is arranged in one end face, and axis pin 8 is fixedly installed in the outer periphery of swivel nut 5, passes through axis pin 8 that fixed plate 6 is arranged, solid
The lower part of fixed board 6 connects counterweight hinge 2 by shaft 3, and torsional spring 7 is arranged in shaft 3.
The utility model effectively reduces the screw thread of jackscrew 10 and wind that foreign object contacts by the way that swivel nut 5 is arranged for jackscrew 10
Danger, can ensure that the screw thread of jackscrew 10 is not bruised, and jackscrew 10 has relative rotation with swivel nut 5, to reduce screw thread rust
Dead risk.
The jackscrew 10 of the utility model relatively rotates under the action of motor with swivel nut 5, meanwhile, in counterweight hinge 2
Its own gravity and baffle 9 under the action of, swivel nut 5 can be made to be maintained at a relatively fixed position, torsional spring 7 can slow down
The impact generated when the thread contact of the screw thread of leading screw 10 and swivel nut 5, the screw thread to reduce jackscrew occur bending and
The risk that screw thread is damaged.
The impact that the rubber sheet gasket 4 of the utility model is subject to also for the screw thread for slowing down jackscrew 10, when jackscrew 10 returns
It falls back on to a certain degree, the end face of swivel nut 5 can be in direct contact motor, the silk for the contact jackscrew 10 that at this moment screw thread of swivel nut 5 can be of short duration
Button, slows down impact using rubber sheet gasket, advantageously reduces screw thread and the risk that bending and screw thread are damaged occur.
