See also Fig. 1, the utility model embodiment provides a kind of reactor threaded hole service kit, comprises stock chasing tool 1, and this stock chasing tool 1 has expansion screw tap 11 and control set for adjusting 12.Control set for adjusting 12 is connected with expansion screw tap 11, and may command expansion screw tap 11 stretches out and withdrawal, makes expansion screw tap 11 corresponding with the threaded hole size.
Particularly, the control set for adjusting 12 of above-mentioned stock chasing tool 1 comprises coarse adjustment portion 122 and the trimming part 123 that push rod 121 and scalable push rod 121 move.In the present embodiment, coarse adjustment portion 122 is the coarse adjustment nut, and trimming part is a trimming bolt, and trimming bolt is arranged in the coarse adjustment nut, can realize the fine setting of trimming bolt at axis direction along the threaded line rotation in the coarse adjustment nut.The coarse adjustment nut sleeve is located in the edge cover 124, and edge cover 124 has internal thread, and the coarse adjustment nut can rotate along threaded line equally, realizes the coarse adjustment of coarse adjustment nut at axis direction.The end face of coarse adjustment nut is provided with index dial 128, behind rotation coarse adjustment nut or the trimming bolt, can observe the displacement of push rod 121 at index dial 128.
The tapering point of push rod 121 is connected with expansion screw tap 11, and this expansion screw tap 11 is the chasing tool 111 of scalable external diameter, and chasing tool 111 radially is respectively arranged with 6 along expansion screw tap 111.The medial surface of chasing tool 111 is wedge shape, and the cone 126 of push rod 121 presses on the wedge shape chasing tool 111, and rotation coarse adjustment nut or trimming bolt move the cone 126 of push rod 121 in wedge shape chasing tool 111, realize the expansion and the withdrawal of chasing tool 111.The center of chasing tool 111 overlaps with the center of threaded hole, and during the location, the bolt that can utilize defective threaded hole next door to be screwed into positions, and guarantees accurate positioning.Control expansion chasing tool 11 simultaneously, the lateral surface of its chasing tool 111 and threaded hole are complementary, rotation chasing tool 111 just can be realized the rethreading hole defect.Chasing tool 111 also is sheathed in the guide cylinder 130, and guide cylinder 130 is fixedlyed connected with cylindrical shell 127, play the guiding role for chasing tool 111 moves by guide cylinder 130.
Long handle chasing tool 1 bottom can swollen screw tap 11 adjustable extent, covered the margin tolerance that reactor pressure vessel master screw M155 * 4-4H5H allows, guarantee can excessively not repair to reactor pressure vessel master screw, can also guarantee that all the main screws on the reactor pressure vessel can both repair, simultaneously, can also pass through trimming bolt, adjust the cutting output of chasing tool 111.
As shown in Figure 2, service kit also comprises the balance device 2 that is used for balance stock chasing tool 1, balance device 2 comprise support 21 and with the corresponding counterweight 22 of stock chasing tool 1 weight, 22 fens other tops of stock chasing tool 1 and counterweight are provided with suspension hook 23, stock chasing tool 1 and counterweight 22 are arranged at the both sides of support 21 by suspension hook 23.Service kit can pass through counterweight 22, regulates the upper and lower end face of stock chasing tool 1 repair on a selective basis screw thread, and regulates the repairing of both sides, double thread hole as required.
As shown in Figure 3, service kit also comprises deep hole testing fixture 3, and the deep hole testing fixture has endoscope 31, outer tube 32 and the interior pipe 33 that is used to observe threaded hole, and in the pipe 33, interior pipe 33 was arranged in the outer tube 32 in endoscope 31 was arranged at.Endoscope 31 is connected power supply, optical signal line, and outer tube 32 inserts in the unthreaded hole, then interior pipe 33 is promoted to upper, and camera light strength is focused, adjusted to endoscope 31, up to clearly seeing the sky internal thread.Pipe 33 in then rotating, the camera lens that interior pipe 33 drives endoscope 31 rotates a circle, and the preceding four button screw threads of observation threaded hole if observe defectiveness, are write down the angle position of defective.Interior pipe 33 is put down lattice (axially having 19 little lattice altogether), observe back four button screw threads, operation steps is the same.Observe the screw thread in the threaded hole successively, finish up to all screw thread observations.
