The spring pin handle 16 slides from one end of the slide groove 18 to the other end, and the pin shaft slides from one end of the guide hole 14 to the other end. A spring is arranged inside the spring pin handle 16, and after the action is completed, it will rebound into the slide groove 18 of the limit plate 17 fixed on the turntable 15, so as to achieve the effect of locking the turntable 15 and preventing the bolt 13 from moving.

[0030] As an optional solution, the valve short connector 9 in this embodiment is a hollow straight tube, and a plurality of convex strips 10 are evenly distributed along the circumferential direction on the upper end of the hollow straight tube. The convex strips 10 can be inserted into the gaps between adjacent spline teeth 7, and the gaps between adjacent spline teeth 7 are larger than the width of the convex strips 10, so that the convex strips 10 and the spline teeth 7 do not need to be aligned when being inserted, and can be easily inserted, making assembly simple and quick.

[0031] The working principle and specific operating steps of the power-assisted arm-type plug valve quick installation device in this embodiment are as follows: by dragging the extended operating rod, the power-assisted manipulator 1 can stay freely in a three-dimensional space within a certain range, and operating the control button on the extended operating rod can make the hydraulic motor 23 in the rotating mechanism 5 drive the worm gear to rotate, and the rotation of the worm gear 22 will drive the quick installation mechanism to rotate together, and the spline teeth 7 of the plug-in cylinder 6 in the quick installation mechanism are connected with the convex strips 10 of the valve short connector 9, driving the valve short connector 9 to rotate, and the plug valve 19 to be installed is connected to the valve short connector 9 through threads, which finally drives the plug valve 19 to be installed to rotate and be installed on the oil pipe with an internal thread. When it is necessary to withdraw the power-assisting manipulator 1, in order to leave the valve short connector 9 and the installed plug valve on the oil pipe, it is only necessary to manually rotate the spring pin handle 16 on the quick-loading mechanism to a certain angle. The spring pin handle 16 rotates with the turntable 15 to make the pin 13 extend outward, and the plug-in tube 6 in the quick-loading mechanism is separated from the valve short connector 9. The power-assisting manipulator 1 can be evacuated together with the extension operating rod, the rotating mechanism 5, and the quick-loading mechanism. Similarly, when it is necessary to remove the valve short connector 9 and the plug valve from the oil pipe, it is only necessary to perform the opposite operation.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
