Abstract
The invention relates to a protective structure in a vacuum cabin, and is applied in a high-speed dynamic balancing test apparatus. The protective structure comprises a cylindrical shell and a steel plate protector, wherein the steel plate protector is fixed on the inner wall of the cylindrical shell and comprises an upper cover panel, a support steel pipe and a lower cover panel. The upper cover panel covers the lower cover panel and comprises a base plate and a side plate. One end of the side plate is fixed on the periphery of the base plate, and the other end of the side plate is connected with the lower cover panel. A cavity is formed between the base plate and the lower cover panel, one end of the support steel pipe is fixed with the base plate, and the other end of the support steel pipe is fixed with the lower cover panel to fix the upper cover panel and the lower cover panel together. The protective structure is reasonably designed, reduces the thickness of a concrete protection layer and protects the interior of the cylindrical shell.

1, causing device volume huge and heavy, assembling and transport are all extremely inconvenient.
2, inner barrel is not protected, and is easily damaged in cylinder.
Summary of the invention
It is an object of the invention to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, thickness of concrete cover can be reduced, safeguard structure in the vacuum chamber of protection inner barrel.
This invention address that the problems referred to above be the technical scheme is that the safeguard structure in a kind of vacuum chamber, including cylinder；It is characterized in that: also include steel plate preventer；Steel plate preventer is fixed on the inwall of cylinder, and it includes upper cover plate, supporting steel pipe and lower cover plate；Upper cover plate covers on lower cover plate；Upper cover plate includes base plate and side plate；One end of side plate is fixed on the surrounding of base plate, and the other end is connected with lower cover plate；Between base plate and lower cover plate, there is cavity；Supporting steel pipe one end and base plate are fixed, and the other end and lower cover plate are fixed, and upper cover plate and lower cover plate are fixed together.
Having supporting steel pore on lower cover plate of the present invention, supporting steel pipe one end is fixed with lower cover plate after supporting steel pore.
Upper cover plate of the present invention has upper cover plate installing hole, described lower cover plate has lower cover plate installing hole；Also including securing member, securing member is fixed through the inwall of upper cover plate installing hole and lower cover plate installing hole and cylinder, is fixed on the inwall of cylinder by steel plate preventer.
Being fixed with on the inwall of cylinder of the present invention and take ear, steel plate preventer is fixed on to be taken on ear.
Steel plate preventer of the present invention is multiple, covers on the inwall of cylinder.
The present invention compared with prior art, has the following advantages and effect:
1, broken blade can be stuck on steel plate preventer after steel plate preventer, it is to avoid broken blade bounce-back is returned to the damage of other blades on rotor.
2, reduce inner barrel breakage probability, need to repair owing to internal vacuum can be destroyed after cylinder breakage at once, maintenance time can be reduced with this after being mounted with the present invention, improve the utilization rate of assay device.
3, the concrete thickness outside cylinder is made to greatly reduce.

Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the present invention is described in further detail, and following example are explanation of the invention and the invention is not limited in following example.
Referring to Fig. 1～Figure 10, the present embodiment is used for vacuum chamber 1, including cylinder 11 and steel plate preventer 2.
Steel plate preventer 2 is fixed on the inwall of cylinder 11.
Steel plate preventer 2 includes upper cover plate 3, supporting steel pipe 4 and lower cover plate 5.
Upper cover plate 3 includes base plate 6 and side plate 7.One end of side plate 7 is fixed on the surrounding of base plate 6.
Upper cover plate 3 covers on lower cover plate 5, the other end of its side plate 7 is connected with lower cover plate 5, and has cavity 14 between base plate 6 and lower cover plate 5, thus makes the present invention have elasticity, base plate 6 can elasticity inside contract when being subject to broken blade shock, and such broken blade would not be subject to very big resilience force.
Supporting steel pipe 4 one end and base plate 6 are welded and fixed, and the other end and lower cover plate 5 are welded and fixed, and upper cover plate 3 and lower cover plate 5 are fixed together, and base plate 6 is played a supporting role when being subject to clashing into,
Having supporting steel pore 8 on lower cover plate 5, supporting steel pipe 4 one end is welded and fixed with lower cover plate 5 after supporting steel pore 8, so easy to assembly, and the installation site of lower cover plate 5 is accurate, and can ensure that each supporting steel pipe 4 can be fixed with lower cover plate 5.
Having upper cover plate installing hole 9 on upper cover plate 3, lower cover plate 5 has lower cover plate installing hole 10, securing member 12 is fixed through the inwall of upper cover plate installing hole 9 and lower cover plate installing hole 10 and cylinder 11, is fixed on the inwall of cylinder 11 by steel plate preventer 2.
Steel plate preventer 2 is multiple, covers on the inwall of cylinder 11.
Being fixed with on the inwall of cylinder 11 and take ear 13, steel plate preventer 2 is fixed on by securing member 12 and takes on ear 13.
