Fast-open type Anti-Typhoon buoyancy module manhole
Technical field
This utility model is related to large floating roof oil tank technical field, the Anti-Typhoon buoyancy module manhole of specifically a kind of fast-open type.
Background technology
Buoyancy module manhole is used for when floating top oil tank buoyancy module overhauls entering buoyancy module use.
Existing problem is:Building in large-scale petroleum filling near by sea or harbour, by typhoon influence, buoyancy module manhole more
Lid is easily taken off.As someone patrols and examines on floating roof, patrol officer may be damaged.
Content of the invention
For solving above-mentioned technical problem, this utility model provides a kind of fast-open type Anti-Typhoon buoyancy module manhole.
This utility model is achieved through the following technical solutions:A kind of Anti-Typhoon buoyancy module manhole of fast-open type, including shell ring and lid
Cover plate in shell ring upper end;The eyelet bolt that described shell ring upper end circumference is provided with equally distributed three or more than three is solid
Determine mechanism;Journal stirrup II that described eyelet bolt fixed mechanism includes being fixed on shell ring periphery and fixing on the cover board with
The relative journal stirrup of journal stirrup II I;It is hinged with eyelet bolt on described journal stirrup II;The end of described journal stirrup I has U-type groove;Institute
The eyelet bolt stated around pin joint rotate when, eyelet bolt end can enter in journal stirrup I U-type groove, eyelet bolt end install
There is wing nut.
It is further:Described cover plate lower surface is fixed with the ring flat-plate that a loop diameter is more than shell ring diameter;Described props up
Ear I is weldingly fixed on ring flat-plate by backing plate I.
Described cover plate lower surface is fixed with rubber slab pad.
Described cover plate upper surface is fixed with a pair of handle.
Described journal stirrup II has two, and two journal stirrups II are positioned opposite;Described eyelet bolt one end is passed through bearing pin, is opened
Mouth pin is hinged between two journal stirrups II.
The adapter that described shell ring rolls for steel plate.
Build tank area what typhoon frequently logged in, the buoyancy module manhole of floating top oil tank relies on eyelet bolt fixed mechanism by cover plate
Locked with shell ring, it is to avoid under the invasion and attack of typhoon, security incident is raised and occurred to buoyancy module cover plate for manhole, install and dismounting is simple
Easy, improve the connection reliability of buoyancy module manhole.
Compared with prior art, the utility model has the advantages that:
1st, maintainer is easy to operate, simple and practical.
2nd, open simply, buoyancy module manhole cover can be locked, and plays wind action of combating typhoon.
3rd, reduced investment, low cost, effect are good.

Specific embodiment
The following is a specific embodiment of the present utility model, in conjunction with accompanying drawing, this utility model is made furtherly
Bright.
In conjunction with shown in Fig. 1 to Fig. 4, a kind of Anti-Typhoon buoyancy module manhole of fast-open type, the adapter that shell ring 1 rolls for steel plate;
Cover plate 3 covers in shell ring 1 upper end;Cover plate 3 lower surface is fixed with the ring flat-plate 5 that a loop diameter is more than shell ring 1 diameter;Cover plate 3 lower surface,
It is fixed with the rubber slab pad 6 of sealing within ring flat-plate 5;Shell ring 1 upper end circumference is provided with equally distributed four eyelet bolts
Fixed mechanism 2.Eyelet bolt fixed mechanism 2 includes vertical by backing plate II 2-6 be weldingly fixed on shell ring 1 periphery a pair
Journal stirrup II 2-5 of arrangement, eyelet bolt 2-4 one end is hinged between two journal stirrup II 2-5 by bearing pin 2-7, split pin 2-8;
Ring flat-plate 5 periphery is welded with one opposing upper and lower with journal stirrup II 2-5 horizontally disposed journal stirrup I 2-3 by backing plate I 2-1,
The end of journal stirrup I 2-3 has U-type groove;When eyelet bolt 2-4 rotates around pin joint, eyelet bolt 2-4 end can enter journal stirrup
The wing nut 2-2 of locking, in I 2-3U type groove, is installed in eyelet bolt 2-4 end.Cover plate 3 upper surface is fixed with a pair
Handle 4.
