Abstract
The invention discloses a location measuring device for an oil well electric push rod. The location measuring device comprises a hollow location measuring square tube which is in a square tube shape. A driving shell is arranged at the bottom of the location measuring square tube; a maintaining motor is arranged in the driving shell; a location measuring notch which is in a long bar shape is formed in the side wall of the location measuring square tube; and a detachable location measuring module is arranged on the location measuring square tube. In the using process, when the electric push rod elongates, the head of the electric push rod extends into the location measuring square tube, and once the head of the electric push rod touches a touch piece of a displacement sensor, the electric push rod stops moving; and accordingly the phenomenon that the electric push rod squeezes an oil well drill core is effectively avoided, and the service life of the oil well drill core is effectively prolonged.

Because the head of the electric push rod adopts the resistance sensor to detect and limit, the contact for a long time is needed, the failure of the drill core is easily caused, and the service life is influenced.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides a position measuring device for an electric push rod of an oil well.
The technical problem of the invention is mainly solved by the following technical scheme:
a position finding device for an oil well electric push rod is characterized by comprising a hollow square tube-shaped position finding square tube, a driving shell is arranged at the bottom of the square tube, a maintenance motor is arranged inside the driving shell, a long strip-shaped position finding notch is formed in the side wall of the square tube, a detachable position finding module is arranged on the square tube, the position finding module comprises a fixed support and a pair of fixed clamping blocks, the fixed support comprises a pair of door-shaped main supports, the heads of the main supports are respectively provided with a door-shaped auxiliary support, the direction of arrangement of the auxiliary supports is perpendicular to the main supports, each fixed clamping block comprises a clamp block base plate which is longitudinally arranged and a pair of clamp plate side plates which are horizontally arranged, and a pair of side plate round holes are respectively formed in each clamp plate, a displacement sensor is arranged between the fixed clamping blocks, a pair of fixed round holes are formed in the bottom of the displacement sensor, and a pair of locking screws respectively penetrate through the side plate round holes and the fixed round holes and are connected with a locking nut.
As a preferred embodiment of the present invention, the fixing bracket is made of stainless steel strips.
The position measuring device for the electric push rod of the oil well has the advantages that: during the use, when electric putter when the extension, electric putter's head stretches into position finding side's pipe, in case electric putter's head touches displacement sensor's contact, and at this moment, electric putter stop motion prevents effectively that electric putter from extrudeing the oil well and bores the core, has effectively prolonged the life of oil well core. The position measuring device for the electric push rod of the oil well has the advantages of simple structure, obvious effect, low cost and strong practicability.
