Description
Technical field
The utility model belongs to ocean engineering machinery field, and in particular to a kind of manhole cover bolt protective cover device, specifically
It is related to a kind of manhole cover bolt protective cover device of ocean engineering platform.
Background technique
Manhole cover is to be seen everywhere on ocean engineering platform, the pattern of manhole cover be also it is all kinds of, have elevated,
Point of flush type and horizontal.And the bolt for fixing manhole cover is understood in operation process because of some meanings due to being exposed to the external world
Other factor and deform, such as shock of weight etc..Manhole cover can not be fixed once after the deformation of the bolt of manhole cover, leads to manhole
Lid can not close, on platform the employee of operation bring security risk, simultaneously because bolt is in manhole cover manufacturing process
Just and Hull Welding, replacement difficulty is big, therefore needs a kind of manhole cover bolt protective cover device, protects bolt not because of unexpected factors
And it deforms.
Utility model content
Technical problems to be solved needed for the utility model are to provide a kind of Novel manhole cover bolt protective cover device, prevent
Manhole bonnet bolt deforms and causes security risk.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of manhole cover bolt protective cover device, to protect manhole bonnet bolt, it is characterised in that: the protection closure assembly by
One piece of top plate and muti-piece vertical plate composition, the top plate are annular plate identical with manhole cover Bolt plate, and the top plate is horizontally disposed,
All the vertical plates are vertically connected at below the top plate, all the vertical plates perpendicular to the annular plate radial direction, it is described vertical
Plate includes the second vertical plate of the first vertical plate of muti-piece and muti-piece, outer 10 ~ 15mm of first vertical plate apart from the annular plate, described
Second vertical plate is arranged in the annular plate along 10 ~ 15mm, first vertical plate and second vertical plate interval, described vertical
The height of plate is higher than 5 ~ 10mm of the manhole bonnet bolt, and the material of the top plate and the vertical plate is steel, the top plate and
The vertical plate passes through welded connecting.
Further, the leg size of the top plate and the vertical plate is 4 ~ 8mm.
Further, the material of the top plate and the vertical plate is Gr.A grades of steel.
Further, the manhole cover bolt protective cover device is set on sunk manhole cover.
Above-mentioned Novel manhole cover bolt protective cover device when in use, covers on the manhole cover opened, and guarantees manhole cover
Bolt manhole cover open when will not be deformed because of unexpected factor.

Specific embodiment
With reference to embodiments, more detailed description is done to the above-mentioned technical characteristic and advantage of the utility model.
As shown in Figures 1 to 4, a kind of Novel manhole cover bolt protective cover device is prevented to protect manhole bonnet bolt 3
The deformed damaged because of unexpected factor of manhole bonnet bolt 3, protects the screw thread of bolt 3 and end not to damage, and extends manhole cover spiral shell
The service life of bolt 3.The manhole cover bolt protective cover device, is made of one piece of top plate 1 and muti-piece vertical plate, the top plate 1 be with
The identical annular plate of manhole cover Bolt plate, the top plate 1 is horizontally disposed, and all the vertical plate is vertically connected under the top plate 1
Side, all for the vertical plate perpendicular to the radial direction of the annular plate, the vertical plate includes the second vertical plate of the first vertical plate of muti-piece 2 and muti-piece
5, outer 10 ~ 15mm of first vertical plate 2 apart from the annular plate, interior edge of second vertical plate 5 apart from the annular plate
10 ~ 15mm, first vertical plate 2 and the setting of second vertical plate 5 interval, the height of the vertical plate are higher than the manhole bonnet bolt
The material of 5 ~ 10mm, the top plate 1 and the vertical plate is steel, and the top plate 1 and the vertical plate pass through welded connecting.Leg
Size is 4 ~ 8mm.
The material of the top plate 1 and the vertical plate is Gr.A grades of steel.
The manhole cover bolt protective cover device is set on sunk manhole cover.
When manhole cover is opened, by entire protective cover appliance cover on manhole bonnet bolt 3, novel protected cover structure can be incited somebody to action
Entire manhole bonnet bolt 3 is isolated from the outside, and mutually constrains between protective cover and manhole, can effectively prevent manhole cover spiral shell
Bolt 3 is deformed due to factors such as weight shock, splashings.Meanwhile 1 shape of top plate of manhole cover protective cover is consistent with manhole shape,
The use of manhole is not influenced.Not only it had protected manhole bonnet bolt but also had not influenced to construct.
The beneficial effects of the utility model are: manhole use finishes, when needing to cover manhole cover, protective cover need to only be born away
?.There is gap between protective cover vertical plate 1 and vertical plate 2, is just grabbed and taken with hand for construction personnel.Whole process is time saving and energy saving,
Other operations are not influenced.Manhole cover bolt protective cover when not in use, can be directly placed on the tray rack of platform, be not take up
Other spaces on platform.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those skilled in the art are practical to this
The various changes and improvements that novel technical solution is made should all be included in the protection scope that the utility model claims book determines
It is interior.
