Abstract
The utility model provides a plug-and-play type oil well load sensor, which belongs to the oil field equipment technology field. The main body of the load sensor has a U-shaped opening; three sensor pressure-bearing heads are disposed on the side perpendicular to the direction of the U-shaped opening channel of the main body, wherein, one of the sensor pressure-bearing head is disposed on one side of the U-shaped opening, the other two are disposed on the other side of the U-shaped opening; a polished rod is disposed in the U-shaped opening channel; a bolt head setting hole and a screw hole are formed on the main on one side of the U-shaped opening; the bolt head setting hole is coaxial and in communication with the screw hole; a screw blind hole is formed on the main body on the other side of the U-shaped opening; the stem of a bolt is screwed in the screw hole, while the tail of the bolt is screwed in the screw blind hole; and the stem of the bolt on the U-shaped opening is disposed with a bolt sleeve. In the utility model, the sensor pressure-bearing heads are designed to forced uniformly; the bolt sleeve can prevent the bolt from loosening; and the sensor has the advantages of safety, reliability, using convenience and easy maintenance.
Description
Technical field
The utility model relates to the oil field equipment technical field, specifically a kind of instant-plugging oil well load transducer.
Background technology
General, the structure that is used for oil pumper oil well load transducer at present mostly is the cylindrical body of column type O type greatly, need remove when installing and using that oil pumper is outstanding to be risen device, fastener nut etc. and be inserted in from the polished rod top, because of the scene height influence the demolition, installation difficulty, cause defectives such as stopping long and installation and maintenance expense height of well time.
Also there is a kind of slotting formula load transducer under the prior art, it is provided with two sensors, make the outstanding device that rises tilt forward and back, cause oil-extractor polish-rod to reach the outstanding excessively too fast wearing and tearing of wirerope that rise easily owing to 2 stressed shakinesses, and because of the sensor openings screw rod exposes, stressed back is easily loosening in use and between the polished rod, even can come off and lose.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of instant-plugging oil well load transducer is provided.
The technical solution of the utility model realizes in the following manner, this instant-plugging oil well load transducer, its structure is that this load transducer main body is " U " shape opening body, be provided with three sensor pressure bearing heads with the perpendicular side of " U " shape open channel direction on the main body, one of them sensor pressure bearing head is arranged on a side of " U " shape opening, two opposite sides that are arranged on " U " shape opening in addition, be provided with polished rod in " U " shape open channel, offering the bolt head on the main body of " U " shape opening part one side puts and boxes out and screw, the bolt head is put and is boxed out and screw coaxial running through of front and back, offer tapped blind hole on the main body of " U " shape opening part opposite side, the bolt body of one bolt is screwed in the screw, the bolt tailspin is connected in the tapped blind hole, and the bolt of " U " shape opening part bolt is with bolt sleeve on one's body.
The screw thread and the bolt thread of described screw and tapped blind hole match.
The beneficial effect that the utility model is compared with prior art produced is:
Three the sensor pressure bearing heads on every side that are distributed in polished rod of this instant-plugging oil well load transducer setting, stressed even, kept the original parallel of this instant-plugging oil well load transducer and poliched rod eye; The setting of the bolt sleeve of the outside of bolt makes to rotate freely by bolt sleeve when screw rod is outside stressed, prevents bolt looseness.
The utlity model has reasonable in design, simple in structure, safe and reliable, easy to use, be easy to characteristics such as maintenance, thereby, have good value for applications.
