Description
Technical field
The utility model relates to a kind of normal pressure or pressure vessels, more particularly, to a kind of manhole device of tank body.
Background technique
Currently, various types of manhole devices generally can be all set in pressure vessel, normal pressure or the construction of mesolow tank body,
Operative employee or maintenance mans are installing equipment, are cleaning and when maintenance and inspection, can also can use people through manhole access device
Hole is aerated, with sharp safety.More commonly used has rotary cap, level to hang lid and vertically hangs three kinds of forms of lid.Rotary cap manhole
It may be mounted at the side of top of the tank and tank body；Manhole with horizonal hanging cover is typically mounted at the top of tank body；Manhole with vertical hanging cover
It is typically mounted at the side of tank body.Rotary cap manhole hangs lid and manhole with vertical hanging cover use scope is wider compared to more horizontal no matter
It is to have to be widely applied very much in top of the tank or side.But rotary cap manhole is arranged in top of the tank, without level
Manhole with hanging cover flexible operation, worker is time-consuming and laborious when opening blind flange, and operation is extremely inconvenient.
Utility model content
The applicant is directed to above-mentioned problem, has carried out Improvement, provides a kind of manhole device of tank body, structure is simple
Compact, flexible to operation, it is time saving and energy saving when blind flange to open or close, and improves production efficiency, mitigates the labor intensity of worker.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solutions:
A kind of manhole device of tank body, the shell ring including top of the tank is arranged in are equipped with flange at the port of the shell ring,
Blind flange is fixedly connected with the flange by stud, nut and gasket, and the axle sleeve that the shell ring side is arranged in is solid by gusset
Surely the shell ring is connected；Pivoted arm is the integral member connected and composed by horizontal segment and vertical section, under the vertical section of the pivoted arm
The axle sleeve that is rotatably connected is held, the vertical section of the pivoted arm is equipped with positioning ring, the positioning ring and the axle sleeve plane contact；
Hanging ring is fixed at the center of the blind flange, and the hanging ring is hooked in the lower end of vertically disposed suspension hook, the suspension hook it is upper
End is rotatably connected the horizontal segment of the pivoted arm, and the upper end of the suspension hook is equipped with stop nut.
It is further:
The outer end of the horizontal segment of the pivoted arm is equipped with extended segment, and casing is sleeved on the extended segment.
Gusset is equipped between the horizontal segment and vertical section of the pivoted arm.
The utility model has the technical effect that
A kind of manhole device of tank body disclosed by the utility model, it is simple and compact for structure, it is flexible to operation, play on or off
It is time saving and energy saving when blind flange to close, and improves production efficiency, mitigates the labor intensity of worker.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, 2, the utility model includes the shell ring 1 that top of the tank is arranged in, and is equipped with flange at the port of shell ring 1
2, blind flange 4 is fixedly connected with flange 2 by stud, nut and gasket 3, and the axle sleeve 11 that 1 side of shell ring is arranged in passes through gusset 12
It is fixedly welded connection shell ring 1, the axis of axle sleeve 11 is vertically arranged, and pivoted arm 8 is connected and composed by horizontal segment 82 and vertical section 81
Integral member, pivoted arm 8 can be formed by steel pipe or rod iron bending, and horizontal segment 82 is mutually perpendicular to vertical section 81, the horizontal segment of pivoted arm 8
Gusset 9 is equipped between 82 and vertical section 81, gusset 9 enhances the intensity of pivoted arm 8, improves the load-bearing capacity of pivoted arm 8.Pivoted arm 8 hangs down
The lower end of straight section 81 is rotatably connected axle sleeve 11, and the vertical section 81 of pivoted arm 8 is equipped with positioning ring 10, positioning ring 10 and 11 plane of axle sleeve
Contact.Hanging ring 13 is fixedly welded on the center of blind flange 4, and hanging ring 13 is hooked in the lower end of vertically disposed suspension hook 5, suspension hook 5 it is upper
End is rotatably connected the horizontal segment 82 of pivoted arm 8, and the upper end of suspension hook 5 is equipped with stop nut 7.
When operative employee or maintenance mans are installing equipment, cleaning and when maintenance and inspection, unclamp and remove on blind flange 4
Stud, nut and gasket 3, rotate pivoted arm 8, make blind flange 4 around the vertical section 81 of pivoted arm 8 axis rotate, thus by flange
Lid 4 is removed from flange 2, and blind flange 4 is hung on pivoted arm 8 by suspension hook 5 and stop nut 7, at this point, operative employee or maintenance mans
Tank body can be entered.In the present embodiment, the outer end of the horizontal segment 82 of pivoted arm 8 is equipped with extended segment 83, and casing 6 is sleeved on extended segment
83, when blind flange 4 is moved away from by rotation pivoted arm 8 from flange 2, operative employee can regard casing 6 as handle, to lengthen rotation
The arm of force, operative employee will more easily control can be moved away from than heavier blind flange, equally can also easily move blind flange when closed
It moves to flange, after blind flange closing, casing 6 can be removed spare.The utility model is simple and compact for structure, easy to operate spirit
It is living, open or close it is more convenient, quick when blind flange, it is time saving and energy saving, greatly save the time of opening and closing, improve maintenance
Efficiency.
