Description
Technical field
The utility model is related to plate column structure improve, it is specially a kind of can applied to the two-sided of plate column internal tray
Open manhole structure.
Background technology
Plate column is a kind of reaction vessel for being widely used in rectifying and absorbing, attached by housing, skirt, the mouth of pipe, tower tray etc.
Part forms.Influenceed, how tower internal tray overhauled by plate column design feature, turn into operating personnel often face and
Must solve the problems, such as.
The content of the invention
The purpose of this utility model be to provide it is a kind of it is two-sided open manhole structure, the maintenance of tower internal tray is difficult to ask
Topic, and reduce shell manhole and quantity is set, it is cost-effective.
The utility model adopts the following technical scheme that realization：
It is a kind of to open manhole structure, including manhole cover applied to the two-sided of plate column internal tray；Opened on the manhole cover
Provided with some mounting holes, inserting stud, the stud bottom fit through the semicircle orifice being opened on clamping plate in each mounting hole,
The manhole cover and clamping plate are assemblied in tray wall both sides by bolt arrangement, are installed on the stud positioned at manhole cover side end outer
Nut, positioned at clamping plate side end install inner nut.
In use, manhole cover is arranged at the manhole of tower tray by clamping plate and bolt arrangement.When needing to open manhole, due to
The bottom of stud coordinates with clamping plate upper half circular hole installs, and screws outer nut or inner nut, can realize and unload manhole cover, real
Now open the purpose of manhole.
The beneficial effects of the utility model are：Solve the problems, such as that the maintenance of tower internal tray is difficult, reduce housing people
Hole sets quantity, cost-effective.
Brief description of the drawings
Fig. 1 represents structural representation of the present utility model.
Fig. 2 represents the enlarged diagram of part A in Fig. 1.
Fig. 3 represents top view of the present utility model.
In figure, 1- tray walls, 2- manhole covers, 3- clamping plates, 4- backing plates, 5- pads, 6- square washers, 7- studs, 8- outer nuts,
9- inner nuts, 10- positioning convex bodies, 11- handles.
Embodiment
Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
It is a kind of to open manhole applied to the two-sided of plate column internal tray, by manhole cover, square washer, clamping plate, backing plate, pad
A few part compositions such as piece, stud, nut, handle.Concrete structure is that manhole cover is arranged on tower tray by clamping plate and bolt arrangement
At manhole, as shown in Figure 1, 2, eight mounting holes are offered on manhole cover 2, i.e., the manhole of tower tray is arranged on by eight pieces of clamping plates
Place.Inserting stud 7, the bottom of stud 7 fit through the semicircle orifice being opened on clamping plate 3 in each mounting hole, that is to say, that
Prune the semicircle orifice that clamping plate is fitted through after a part in the bottom of stud 7（The section of stud bottom is semicircle）, due to semicircle
The design in hole, when screwing outer nut or inner nut, stud will not rotate.The manhole cover 2 and clamping plate 3 pass through spiral shell
Stud structure is assemblied in the both sides of tray wall 1, specifically, clamping plate 3 is L-type clamping plate, the short side of the L-type clamping plate under bolt effect with
Laterally contacted in manhole cover 2, pad 5 is set between the manhole cover 2 and tray wall 1, between the L-type clamping plate and tray wall 1
Backing plate 4 is set.The presence of backing plate and pad enables manhole cover and clamping plate to be brought into close contact with tray wall.The stud 7 is upper
Outer nut 8 is installed, positioned at clamping plate side end installation inner nut 9 in manhole cover side end.Between the outer nut 8 and manhole cover 2
Square washer 6 is set.
As shown in figure 3, the position up and down of the manhole cover 2 is provided with four positioning convex bodies 10, the people of the tray wall 1
Relevant position offers four locating slots up and down at hole, left and right skew will not be so produced when installing manhole cover, afterwards
Bolt arrangement is tightened, manhole cover is arranged at the manhole of tower tray.
As shown in figure 3, handle 11 is welded on manhole cover.
After manhole cover is positioned by four positioning convex bodies, connected using square washer, clamping plate, backing plate, pad by stud, nut
It is connected at the manhole of tower tray, screws any end nut of stud, can open manhole.
The scope of the requires of the utility model protection is not limited to above embodiment, for those skilled in the art
Speech, the utility model can have a various deformation and change, it is all made within design of the present utility model with principle any repair
Change, improve and equivalent substitution all should be included in the scope of protection of the utility model within.
