Description
Technical field
The invention belongs to underwater maintenance technical field, be specifically related to one remote backing-up screw and locking cap and reform technology thereof under water.
Background technique
Due to cause specific, original screw comes off from countersunk head fillister head screw hole, need carry out under water screw repacking and locking, but personnel can not closely operate again, need from more than the water surface carrying below relevant device to the water surface, and accurate positioning equipment is in maintenance station, carries out the repacking of position, screw counter bore hole and backing-up screw, locking cap.
Summary of the invention
The object of the present invention is to provide one remote backing-up screw and locking cap and reform technology thereof under water, so that below more than the water surface remote accurately conveying equipment to the water surface, carry out the repacking of position, screw counter bore hole and backing-up screw, locking cap.
For achieving the above object, the technical solution used in the present invention is:
One is remote backing-up screw and locking cap under water, and described backing-up screw one head is hexagon head, is disc structure in the middle part of backing-up screw one, and described short locking cap is cylindrical shape one end open structure.
One is remote backing-up screw and locking cap under water, and described backing-up screw two head is hexagon head, is disc structure in the middle part of backing-up screw two, and the locking cap of described length is cylindrical shape one end open structure.
Described backing-up screw two has hexagonal rotation prevention structure.
The locking cap of described length loads from backing-up screw two rear portion, wraps disc structure in the middle part of backing-up screw two.
The interior hexagonal anti-loosing of the locking cap of described length is greater than short locking cap.
One is remote backing-up screw and locking cap reform technology under water, and backing-up screw and locking cap need be assembled in advance; Namely the processing of position, screw counter bore hole carry out reaming on basis, archioporus position; Antiratchetting groove has interior antiratchetting groove and outer antiratchetting groove, and interior antiratchetting groove is that counterbore inside 1/3rd disc amasss pit, each one of left and right; Outer antiratchetting groove is end is semicircle, has the segmented cone shape pit of tapering, at circumferentially uniform three; After backing-up screw and the assembling of locking cap, to be arranged in screw hole and to complete screw threads for fastening; Then locking cap portion strut carry out to antiratchetting groove locking.
The refiting scheme of three kinds of patterns is obtained: the backing-up screw one of anti-loose one, short locking cap and interior antiratchetting groove by the combination that backing-up screw, locking cap are different with antiratchetting groove; The backing-up screw two of anti-loose two, long locking cap and interior antiratchetting groove; The backing-up screw two of anti-loose three, long locking cap and outer antiratchetting groove.
Beneficial effect acquired by the present invention is:
The present invention uses the equipment transporting system of high accuracy remote, from the above conveying equipment of the water surface and backing-up screw to repair works under water station; Use electric discharge machining apparatus under water to carry out the processing of position, screw counter bore hole and antiratchetting groove, re-use special tool and backing-up screw is screwed into and carries out locking operation: (1) is remote processing and repacking under water; (2) uniqueness screw check structure under water; (3) multiple locking mode.
Accompanying drawing explanation
Fig. 1 is the machining sketch chart of position, screw counter bore hole and antiratchetting groove;
Fig. 2 is backing-up screw and locking cap schematic diagram;
Fig. 3 is the scheme of installation of backing-up screw and locking cap;
In figure: 1, archioporus position; 2, interior antiratchetting groove; 3, position, screw counter bore hole; 4, outer antiratchetting groove; 5, backing-up screw one; 6, short locking cap; 7, backing-up screw two; 8, locking cap is grown; 9, anti-loose one; 10, anti-loose two; 11, anti-loose three.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 2, backing-up screw and locking cap respectively have two kinds.Backing-up screw head hexagon head matches with special long-range screw installation tool head, and its width and length are all customization, and the hexagon head of backing-up screw one also plays the effect preventing locking cap stop simultaneously; Large-size disc structure in the middle part of backing-up screw, be close to connected piece, play the fastening effect of plain screw, simultaneously for backing-up screw 1, it is simultaneously 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 open structure.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 loads from backing-up screw rear portion, needs to wrap disc structure in the middle part of backing-up screw, therefore to obtain more longer by shorter locking cap 6.In a pre-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, namely on basis, archioporus position 1, 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 that a counterbore inside about 1/3rd disc amasss pit, each one of left and right.Outer antiratchetting groove 4 is ends is semicircle, and band certain taper, segmented cone shape pit, at circumferentially uniform three.
After backing-up screw and the assembling of locking cap, by special Remote Installation instrument, to be arranged in screw hole and to complete screw threads for fastening; Then use special tool locking cap portion strut carry out to antiratchetting groove locking; Inside and outside two kinds of antiratchetting grooves need two kinds of different special tool operations; The refiting scheme of three kinds of patterns is obtained: the backing-up screw 1 of anti-loose 1, short locking cap 6 and interior antiratchetting groove 2 by the combination that backing-up screw, locking cap are different with antiratchetting groove; 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 Figure 3.
