Equipment technical field.
Background technology
The units such as metallurgy, chemical industry have a large amount of pipelines, mostly make somebody a mere figurehead and are connected between laying, pipeline by flange, between flange
Sealed by sealing gasket, because pipeline medium is varied, particularly conveys the pipeline of Korrosionsmedium, be easily corroded rotten
Wear, when changing sealing gasket operation and repairing pipeline operations, flange top need to be opened to replacing sealing gasket or block up, take out blind plate.
At present in production, the prefabricated fixed top opening in a small amount of flange both sides, but also substantial amounts of flange connections do not have
Have prefabricated, due to many reasons such as production and media, it is impossible to Site Welding top opening, so opening operation band to these flange tops
Very big difficulty is carried out.Usually operation typically pries open flange using crowbar, because the spacing pried open is less than normal, and cleaning sealing surface is very not
It is convenient, and be not easy to clean out, cause that leakage phenomenon occurs after operation, while also very dangerous, crowbar is easily slipped, and is caused
Tong, the injury such as fall down, collide, and also needing to many people operation simultaneously.It is long to there is the time, Ren Yuanduo, and intensity is big, efficiency
It is low, the drawback such as potential safety hazard is more.Therefore, a kind of new scheme of exigence solves the technical problem.

Easy to use, position is adjustable, efficiency high.
In order to solve technical problem present in prior art, the technical solution of the utility model is as follows:A kind of tube method
Blue top opening, it is characterised in that the top opening includes clamping device body and bracket, the bracket is welded on clamping dress
Put centre position.
As a kind of improvement of the present utility model, the clamping device body is set to semicircular arc, arc and pipeline arc
Degree matching, bracket welding end surface is with arc clamping device into 90 degree.
As a kind of improvement of the present utility model, the clamping device uses thickness 5mm, width for 100mm steel plate system
Make.
As a kind of improvement of the present utility model, the bracket end plates are 100mm, long 150mm with thickness 10mm, width
Steel plate makes.For installing the effect of opening of jack top.
As a kind of improvement of the present utility model, the bracket reinforcing plate makes of two pieces of 10mm thickness steel plates, length
100mm, width 80mm steel plate make.It is welded between corbels support plate, plays booster action.
As a kind of improvement of the present utility model, the corbels support plate makes of two pieces of 10mm thickness steel plates, length
110mm, width 100mm steel plate make.With bracket end plates vertical welding, play a supportive role.
Relative to prior art, the advantage of the technical scheme is as follows:1)The technical scheme structure design is compact ingenious, altogether
Have 4, two pieces constitutes one group, and two groups are separately mounted in the side ducts of flange two when using, spacing can according to jack length with
And job requirements are adjusted flexibly, bracket end face is horizontally situated, and two groups relative, is then fastened with bolt, makes device and pipeline
It is tightly fastened, during operation, jack is installed between bracket end plates, you can flange is opened on top efficiently, safe, obtains operation bar
Part;2)The technical scheme cost is relatively low, is easy to further popularization and application.

Embodiment
In order to deepen to be appreciated and understood by of the present utility model, with reference to the accompanying drawings and detailed description, further it is situated between
Continue the utility model.
Embodiment 1:Referring to Fig. 1, a kind of pipe flange top opening, the top opening includes the He of clamping device body 1
Bracket 2, the bracket is welded on clamping device centre position;The clamping device body is set to semicircular arc, arc and pipe
Road radian matching, bracket welding end surface is with arc clamping device into 90 degree.The technical scheme structure design is compact ingenious, main suitable
Different areas of activity is opened on pipe flange top for diameter 500mm or so, and flange spacing is difficult to be pried open with crowbar or working space is narrow
Substantially, it is advantageous in that simple in construction small position effect, and safe and reliable, easy to use, position is adjustable, efficiency high.
Embodiment 2:Referring to Fig. 1, Fig. 2, as it is of the present utility model it is a kind of improve, the clamping device using thickness 5mm,
