Description
Technical field
The utility model relates to slewing experiment protector field, particularly a kind of for preventing from lifting airscrew from dishing out hurting sb.'s feelings and the protective screening that arranges.
Background technology
Along with the development of society; helicopter application is more and more extensive; China increases the research and development progress to Helicopter Technology; in helicopter R&D process, the experiment of its slewing is easily caused danger; therefore the capable protection of device adopting protection safety is generally needed; but the protector of lifting airscrew is firm not at present, and install complicated, and in use it is keeped in repair and clean all inconvenient.
Summary of the invention
For solve the problems of the prior art, the utility model provide a kind of reasonable in design, manufacturing cost is lower, anti-impact force is strong, the slewing experiment protective screening of installation and maintenance easy to clean.
For solving the problems of the technologies described above the technical solution of the utility model be: a kind of slewing experiment protective screening, comprise steel column vertical rod, clip, grid screen, it is characterized in that: described grid screen is made up of housing, gauze wire cloth, described gauze wire cloth surrounding outer is provided with the press strip of band screw, described housing is welded by the square steel with screw, its left and right sides is provided with earmuff, fixed by the press strip of bolt and gauze wire cloth before and after it, described hoop sleeve is connected in steel column vertical rod, and is provided with the draw-in groove matched with earmuff.
Described steel column vertical rod internal diameter from top to bottom progressively expands, slightly tapered shape.
Four angles of described housing are provided with angle bar.
Described steel column vertical rod and grid screen may be combined with circular, square, oval, rhombus, leg-of-mutton protective screening.
Described housing can arrange composite steel silk screen.
The utility model is by transforming current protecting screen structure, successfully produce the protective screening that can adapt to different places shape, this protecting screen structure is firm simultaneously, anti-impact force is strong, and adopt Combined net flase floor not only easy for installation, and be easy to carry out keeping in repair and cleaning, greatly reduce use cost, therefore there are wide market prospects.
Accompanying drawing explanation
Fig. 1 is the utility model protective screening plane structure schematic diagram;
Fig. 2 is the utility model grid plated construction schematic diagram;
Fig. 3 is the structural representation of the utility model clip.
Specific embodiment
As Figure 1-3, a kind of slewing experiment protective screening, comprise the steel column vertical rod 1 be fixed on high-strength bolt on prefabricated concrete pedestal, clip 2, grid screen 3, described grid screen 3 is by housing 5, gauze wire cloth 8 is formed, described gauze wire cloth 8 surrounding outer is surrounded by the press strip of band screw, described housing 5 is welded by the square steel of band screw, the upper bottom of its left and right sides is welded with earmuff 4, its front and rear part is fixed with the press strip of a gauze wire cloth 8 respectively by bolt, form two web frame, improve the anti-impact force of protective screening, the internal diameter that described clip 2 is socketed in from top to bottom progressively expands, in slightly tapered steel column vertical rod 1, its height is parallel with the earmuff 4 of housing 5, and earmuff 4 is fixed in its draw-in groove 7.
Four angles of described housing 5 are welded with angle bar 6.
Described steel column vertical rod 1 is welded by plurality of steel plates.
By changing the angle of draw-in groove 7 on clip 2, steel column vertical rod 1 and grid screen 3 may be combined with circular, square, oval, rhombus, leg-of-mutton protective screening.
The above; be only this practicality preferably detailed description of the invention; but the utility model protection domain is not limited thereto, is equal to according to the technical solution of the utility model and inventive concept thereof and replaces or change, all should be encompassed within protection domain of the present utility model.
