Description
Technical field
The utility model belongs to ocean engineering machinery field, and in particular to a kind of manhole bonnet bolt guarantor of ocean engineering platform
Guard apparatus.
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 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 packet
Include size annular plate identical with manhole cover Bolt plate, several bolts hole and two handles, the bolt hole and the manhole cover
Bolt corresponds, and the thickness of the annular plate is 5 ~ 10mm longer than the length of the manhole bonnet bolt, the diameter of the bolt hole
Diameter than the manhole bonnet bolt is 1 ~ 2mm big, and the annular plate is steel plate, and described two handles are symmetrically fixedly connected on institute
It states on annular plate, by being welded to connect, leg size is 4 ~ 8mm for the annular plate and the handle.
Further, the handle is door type, annular or upright post type.
Further, the material of the handle is the round steel of Φ 10.
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 factors.

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 5, a kind of Novel manhole cover bolt protective cover device prevents people to protect manhole bonnet bolt
Hole bonnet bolt deformed damaged because of unexpected factors, protects the screw thread of bolt and end not to damage, and extends making for manhole cover bolt
Use the service life.The protection closure assembly includes size annular plate 1 identical with manhole cover Bolt plate 4, several bolts hole 7 and two handles
2, the bolt hole 7 is corresponded with the manhole bonnet bolt 3, and the thickness of the annular plate 1 is longer than the manhole bonnet bolt 3
Long 5 ~ 10mm is spent, the diameter of the bolt hole 7 is 1 ~ 2mm bigger than the diameter of the manhole bonnet bolt 3, and the annular plate 1 is steel plate,
Described two handles 2 are symmetrically fixedly connected on the annular plate 1, and the annular plate 1 and the handle 2 are connected by welding
It connects, leg size is 4 ~ 8mm.
The handle 2 is door type, annular or upright post type.
The material of the handle 2 is the round steel of Φ 10.
The manhole cover bolt protective cover device is set on sunk manhole cover.
As shown in Fig. 7 and Fig. 6, respectively the schematic diagram of door shape and ring-shaped handle, the size of door shape handle are 150
75 mm x R25 of mm x, the size of ring-shaped handle are the annulus of R75.
The beneficial effects of the utility model are:
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 bolt 3 is isolated from the outside, and mutually constrains between protective cover and manhole, can effectively prevent manhole bonnet bolt 3 by
It is deformed in factors such as weight shock, splashings.Meanwhile 1 shape of manhole cover protective cover annular slab is consistent with manhole shape, does not influence
The use of manhole.Manhole bonnet bolt is protected not influence to construct again.
Manhole use finishes, and when needing to cover manhole cover, need to only bear protective cover away.It is welded on protective cover annular slab 1
There is the handle 2 for construction personnel's dismounting, is just grabbed and taken with hand for construction personnel.Whole process is time saving and energy saving, does not influence other
Operation.Manhole cover bolt protective cover when not in use, can be directly placed on the tray rack of platform, be not take up its on platform
His space.
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.
