Description
Technical field
The present invention relates to mechanical device, and in particular to a kind of hand hole device of pressure vessel.
Background technology
What hand hole is, hand hole is manhole, and the hand for workman gos deep into equipment, and equipment is cleaned, safeguard, examined
Repair.Pressure vessel sets hand hole device to need good air-tightness, and the air-tightness of existing hand hole device awaits improving.
The content of the invention
The invention provides a kind of pressure vessel hand hole device, the purpose of the present apparatus is designed：The present apparatus is directed to pressure appearance
There is provided a kind of good hand hole device of close performance for device.
The invention provides following technical proposals：A kind of pressure vessel hand hole device, the hand hole device includes top plate, lining
Plate, section pipe, manhole pressing plate, bolt, nut, packing ring, the lower end of the bolt are fixedly connected with the top plate, under the section pipe
End is connected with the top plate, and the liner plate is located between the top plate and the section pipe, and the liner plate is managed with the top plate, section
Connection, the section pipe is welded with the pressure vessel wall, and manhole pressing plate described in the bolt-through, the manhole pressing plate crimps institute
State section pipe, the upper end twist-on of the bolt and the bolt.The upper end of the bolt is fixedly connected with rope body.
Beneficial effects of the present invention are as follows：Open the process that hand hole device is not overhauled：Unscrew nut 6 so that top plate 1
Separated with section pipe 3, continue to unscrew nut 6 until nut 6 departs from bolt 5.Human hand stretches into device interior by saving pipe 3 and examined
Repair, safeguard, clear up.It is described to restrict body 9 to draw the present apparatus, it is to avoid device falls into device interior, can not looked for.Such as kiteflying
Equally, it is only necessary to drag the i.e. recoverable present apparatus of this rope body 9.The process of fastening and the process of above-mentioned opening maintenance are opposite.The present apparatus
Being directed to pressure vessel, there is provided a kind of good hand hole device of close performance.
Brief description of the drawings
Fig. 1 is the structural representation of pressure vessel hand hole device of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described with specific embodiment.
In Fig. 1：Top plate 1, liner plate 2, section pipe 3, manhole pressing plate 4, bolt 5, nut 6, packing ring 7, pressure vessel wall 8, rope body
9。
A kind of pressure vessel hand hole device, the hand hole device includes top plate 1, liner plate 2, section pipe 3, manhole pressing plate 4, bolt
5th, nut 6, packing ring 7, the lower end of the bolt 5 are welded with the top plate 1, and the lower end of the section pipe 3 is connected with the top plate 1,
The liner plate 2 is between the top plate 1 and the section pipe 3, and the liner plate 2 is connected with the top plate 1, section pipe 3, the section
Pipe 3 is welded with the pressure vessel wall 8, and the bolt 5 runs through the manhole pressing plate 4, and the manhole pressing plate 4 crimps the section pipe
3, the upper end twist-on of the bolt 5 and the bolt 5.The upper end of the bolt 5 is fixedly connected with rope body 9.
Open the process that hand hole device is not overhauled：Unscrew nut 6 so that top plate 1 with section pipe 3 separate, continue to unscrew spiral shell
Mother 6 is until nut 6 departs from bolt 5.Human hand stretches into device interior by saving pipe 3 and is overhauled, safeguards, clears up.The rope body 9
In order to draw the present apparatus, it is to avoid device falls into device interior, can not looked for.As kiteflying, it is only necessary to drag this rope body 9 i.e.
The recoverable present apparatus.The process of fastening and the process of above-mentioned opening maintenance are opposite.
