The embodiment of the present application provides the manufacture method of two kinds of gravity anchors: referring to Fig. 4, method one may further comprise the steps:
Step 100: make the housing (top of housing is that cone shape, middle part are that cylindrical shape, bottom are the inverted cone shape) of anchor body 1 shape, make the housing (three cone post shapes sizes are identical) of the first cone post 41, the second cone post 42 and third hand tap post 43 shapes.
Step 200: the bottom of U-shaped upper lift ring 2 is embedded to inside from the upper face of the housing of anchor body 1 shape, the housing of the first cone post 41, the second cone post 42 and third hand tap post 43 shapes is embedded to inside from the bottom end surface of anchor body 1 shape housing.
Step 300 a: end of the bottom of U-shaped side suspension ring 3 is embedded to inside from the middle part surface of anchor body 1 shape housing, the other end of the bottom of U-shaped side suspension ring 3 is embedded to inside from the surface of a cone post (the first cone post 41, the second cone post 42 and the third hand tap post 43 any one) shape housing.
Step 400: to the inside pouring molten steel of anchor body 1 shape housing, the first cone post 41, the second cone post 42 and third hand tap post 43 shape housings, treat molten steel cools.
Referring to Fig. 5, method two may further comprise the steps:
Step 500: the housing (top of housing is that cone shape, middle part are that cylindrical shape, bottom are the inverted cone shape) of making anchor body 1 shape.
Step 600: with the upper lift ring 2 of upper lift ring 2(such as U-shaped structure) bottom is embedded to inside from the upper face of anchor body 1 shape housing, with the side suspension ring 3 of side suspension ring 3(such as U-shaped structure) the bottom imbed inside from the middle part surface of anchor body 1 shape housing.
Step 700: toward anchor body 1 shape enclosure interior pouring molten steel, after molten steel cools, form anchor body 1.
Step 800: with the bottom of transverse arresting apparatus (comprising the first cone post 41, the second cone post 42 and third hand tap post 43) fixing (by the mode of welding) at anchor body 1.
The principle of work of the gravity anchor that the embodiment of the present application provides is as follows: when using gravity anchor, gravity anchor is connected with wirerope by the chain link 5 with change on upper lift ring 2 and the side suspension ring 3, and wirerope is connected on the winch on boats and ships or the platform by fairlead.Can realize come-up, the sinking and fixing of boats and ships or platform by winch control wirerope.The top of the anchor body 1 of gravity anchor is pyramidal structure, can make gravity anchor reduce resistance when rising.Inverted cone-shaped structure is adopted in the bottom of the anchor body 1 of gravity anchor, and gravity anchor can easierly be sunk in the water-bed mud, has increased the vertical grip of gravity anchor.Fixed three transverse arresting apparatus on the anchor body 1 of gravity anchor, can prevent that gravity anchor from larger lateral displacement occuring, and has guaranteed the stability of gravity anchor at the bottom, thereby has made boats and ships or the platform held stationary that is connected with gravity anchor.The method one of the manufacturing gravity anchor that the application provides, upper lift ring 2 and side suspension ring 3 are embedded in the anchor body 1, increase the stability of upper lift ring 2 and side suspension ring 3, simultaneously the first cone post 41, the second cone post 42 and third hand tap post 43 have been welded on the bottom of anchor body 1, simple and convenient during production.Simultaneously, the method two of the manufacturing gravity anchor that the application provides, not only upper lift ring 2 and side suspension ring 3 are embedded in the anchor body 1, increased the stability of upper lift ring 2 and side suspension ring 3, and the first cone post 41, second cone post 42 and the third hand tap post 43 of anchor body 1 bottom also hidden in the anchor body 1, increased the stability of the first cone post 41, the second cone post 42 and third hand tap post 43.
The embodiment of the present application has following beneficial effect:
1, the turbination structure is adopted in the bottom of gravity anchor, can be easy to enter in the water-bed mud, thereby larger grip is provided in vertical direction.
2, be applicable to different water area conditions, can recycling after use.
3, be fixed with transverse arresting apparatus on the anchor body of gravity anchor, can prevent that gravity anchor from larger lateral displacement occuring, and has guaranteed the stability of gravity anchor at the bottom, thereby has made boats and ships or the platform held stationary that is connected with gravity anchor.
4, the upper lift ring of gravity anchor and side suspension ring all are embedded in the anchor body, are connected firmly, and have increased the service life of gravity anchor.
5, simple in structure, cost is lower.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical scheme that the application is described, although with reference to example the application is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the application's technical scheme, and not breaking away from the spirit and scope of present techniques scheme, it all should be encompassed in the middle of the application's the claim scope.
