Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 4, Figure 5, backing-up screw and locking cap respectively have two kinds.Backing-up screw head hexagon head matches with special-purpose long-range screw setting tool head, and its width and length are all customization, and the hexagon head of backing-up screw one also plays the effect that prevents locking cap stop simultaneously; The large-size disc structure at backing-up screw middle part, be close to connected piece, play the fastening effect of plain screw, simultaneously for backing-up screw 1, its while is as the bottom support of locking cap, for backing-up screw 27, it also has hexagonal rotation prevention structure except disc structure, plays locking cap anti-rotation and anti-fall function.Locking cap main body is cylindrical shape one end hatch frame.Because the locking cap rotation prevention structure of two kinds of backing-up screws is different, so the rotation prevention structure of locking cap is also had any different, the interior hexagonal anti-loosing of long locking cap 8 is larger than short locking cap 6; And long locking cap 8 is to pack into from backing-up screw rear portion, need to wrap backing-up screw middle part disc structure, therefore will shorter locking cap 6 more longer.Before installation, backing-up screw and locking cap need be assembled in advance.
The processing of position, screw counter bore hole 3 only has a kind of form, on 1 basis, archioporus position, carries out reaming, to meet the installing space demand of backing-up screw and locking cap by electric discharge machining apparatus under water.
Antiratchetting groove has two kinds of forms, interior antiratchetting groove 2 and outer antiratchetting groove 4, and they form processing by electric discharge machining apparatus under water.Interior antiratchetting groove 2 is the long-pending pits of inner approximately 1/3rd discs of a counterbore, each of left and right.Outer antiratchetting groove 4 is that end is semicircle, with certain taper, and part cone-shape pit, on circumference uniform three.
After backing-up screw and the assembling of locking cap, by special-purpose Remote Installation instrument, be arranged in screw hole and complete screw threads for fastening; Then use special tool that locking cap portion is strutted to carrying out in antiratchetting groove locking; Inside and outside two kinds of antiratchetting grooves need two kinds of different special tool operations; By backing-up screw, the combination different with antiratchetting groove of locking cap, obtain the refiting scheme of three kinds of patterns: the backing-up screw 1 of anti-loose 1, short locking cap 6 and interior antiratchetting groove 2; The backing-up screw 27 of anti-loose 2 10, long locking cap 8 and interior antiratchetting groove 2; The backing-up screw 27 of anti-loose 3 11, long locking cap 8 and outer antiratchetting groove 4.As shown in Fig. 6, Fig. 7, Fig. 8.
