Abstract
The invention provides a device for preventing disengaging of a screw pump and an oil-sucker rod. A rotating shaft of the oil-sucker rod is arranged in a cylinder inner hole of a cylinder body by an end cover and is internally provided with Archimedean curve wall. A key is arranged at one side of the rotating shaft which penetrates through the cylinder inner hole by a spring, and a connecting hole is arranged at the other side of the cylinder body, internal threads of the connecting hole is arranged on a circumferential wall of the connecting hole. As the key arranged on the rotating shaft rotates along the Archimedean curve in the cylinder body, thus realizing the purpose that the normal corotation and contrarotation can not cause disengaging; a mechanism connecting the oil-sucker rod and the screw pump for pumping oil can prevent the oil-sucker rod from dropping off; the device is suitable for oil-pumping device of the screw pump.
Description
Technical field
The present invention is to provide the oil production equipment parts of mechanical field, specifically prevent the device of screw pump and pumping rod disengaging.
Background technology
Before the present invention proposed, the screw pump sucker rod was direct-connected by box cupling, when operate as normal, and positive hour hands rotation, transfer torque.When stopping when breaking down, sucker rod release lever physical efficiency is reversed counterclockwise, under high-revolving situation, causes that shackle comes off between bar and the bar, causes oil well to stop production, and need salvage parts.
Summary of the invention
In order to overcome the generation of existing screw pump and sucker rod ease of connection dropout phenomenon, the invention provides a kind of device that prevents screw pump and pumping rod disengaging.This device interacts by archimedes curve wall set in key set in rotating shaft and the cylindrical shell, solves the technical problem that the sucker rod reverse rotation is not threaded off.
The scheme that technical solution problem of the present invention is adopted is: the sucker rod rotating shaft is installed in the cylindrical shell endoporus of cylindrical shell by end cap, be provided with the archimedes curve wall in it, rotating shaft one side of hole site is equipped with key by spring in penetrating cylindrical shell, opposite side at cylindrical shell is provided with connecting hole, is provided with the connecting hole internal thread on the peripheral wall of connecting hole.
Good effect is: because set key Yan Ajimidequxianbi in cylindrical shell rotates in the rotating shaft, can realize normally rotating and reverse the purpose of not threading off.Can prevent in sucker rod is connected the mechanism of oil pumping with screw pump that sucker rod and screw pump from breaking takes off.Be suitable for using in the screw pump oil production device.
Description of drawings
Fig. 1 is a structure chart of the present invention
Fig. 2 is a cylindrical shell A-A sectional view of the present invention
Fig. 3 is the sectional view of rotating shaft of the present invention in cylindrical shell,
Among the figure, 1. cylindrical shell, 1.1. cylindrical shell endoporus, 1.2. archimedes curve wall, 2. end cap, 3. rotating shaft, 4. connecting hole, 4.1. connecting hole internal thread, 5. key, 6. spring.
The specific embodiment
According to the figure, sucker rod rotating shaft 3 is installed in the cylindrical shell endoporus 1.1 of cylindrical shell 1 by end cap 2, be provided with archimedes curve wall 1.2 in it, rotating shaft one side of hole site is equipped with key 5 by spring 6 in penetrating cylindrical shell, opposite side at cylindrical shell is provided with connecting hole 4, is provided with connecting hole internal thread 4.1 on the peripheral wall of connecting hole.
The moving cylindrical shell rotation of archimedes curve cornice is prolonged in the rotating shaft that key is installed in the cylindrical shell endoporus, key orders about it by spring under the effect of curved wall and cylindrical shell is linked up with transfer torque.When rotating shaft when just changeing, key is stuck in the minimum position of archimedes curve wall, tangles the cylindrical shell rotation, realizes the transmission of torsional forces.When rotating shaft is when counter-rotating, bond energy is skipped the minimum position of archimedes curve wall, with the cylindrical shell hook, and transfer torque not, thus discharge the inertia revolving force, and keep sucker rod and the original connection status of screw pump.
Wherein connecting hole is used for spiral and connects other parts or sucker rod, owing to be provided with internal thread in the connecting hole, adopts right-hand thread to spin when being connected with other parts usually, so, when counter-rotating appearred in rotating shaft, then the parts of right-hand thread screw-in can be subjected to the effect of its revolving force and thread off, and cause coming off with sucker rod.When using of the present invention device, owing to, can realize just changeing and carry out torque transmission, and do not transmit torsion when reversing by archimedes curve wall effect set in key and the cylindrical shell, so can not breaking, do not take off the parts that connected in the maintenance connecting hole.
Therefore, in screw pump oil production device, install after apparatus of the present invention, just can prevent the generation of sucker rod and screw pump counter-rotating dropout phenomenon.Thereby the appearance probability of minimizing stopping production accident improves oil recovery efficiency and the application life of the mechanism that pumps.
