Abstract

The invention relates to an inserted tripping device. The device comprises a moving inner cylinder, a middle cylinder, an outer cylinder, a cam, a rotating handle, a supporting seat and a pressing rod; the moving inner cylinder penetrates through the supporting seat and eccentrically and movably cooperates with the cam, one end of the moving inner cylinder is provided with a T-shaped cylinder, the other end of the moving inner cylinder is provided with a long straight strip, the two sides of the T-shaped cylinder are provided with hooks, and the hooks and the long straight strip are located at the same side; one end of the middle cylinder is provided with a cylindrical cylinder, the other end of the middle cylinder is provided with an arc-shaped long strip, and the inner portion of the cylindrical cylinder is provided with an annular flange; the inner circumferential surface of the outer cylinder comprises a flat and an arc surface which are symmetrically arranged; the arc surface of the outer cylinder cooperates with the outer arc-shaped surface of the arc-shaped long strip of the middle cylinder, the inner wall of the cylindrical cylinder cooperates with a drive rod, and the inner diameter of the flange cooperates with a detachment button in the drive rod; the detachment button is provided with an annular groove, the outer cylinder is used for pressing the hooks into the annular groove of the detachment button, and the hooks are connected with the detachment button.

Description

technical field [0001] The invention relates to the technical field of installation of nuclear reactor components, in particular to a plug-in release device. Background technique [0002] The drive rod part of the nuclear reactor is a key component used to connect the control rod assembly and adjust the height of the control rod. It is mainly composed of drive rods, disassembly buttons, flexible joints and other parts. The existing tripping method for the driving rod is mainly to trip the driving rod by connecting the disassembly button and the driving rod through the device when the driving rod is completely exposed outside, but it is impossible to realize that the driving rod is in the slender tube or in an invisible area Perform the trip function. [0003] Therefore, there is a need for a device that enables the control rod and the drive rod to realize the manual release connection function under special conditions. Contents of the invention [0004] The object of the...
