Description
Technical field
This utility model relates to the flexible pressure relief device of a kind of outdoor billboard.
Background technology
China is vast in territory, and coastline is very long, and outdoor billboard all can be made by the strong wind of northwest and the typhoon of southeastern coast
Becoming damage in various degree, the especially Super Typhoon of southeastern coast, its destructive power is just well imagined.
Utility model content
The purpose of this utility model is to provide the outdoor billboard of a kind of flexible release resisting Super Typhoon.
To achieve these goals, the technical solution of the utility model is: provide a kind of flexible pressure relief device, including lower vertical
Post, bottom plate, lower limiting board, convolution guide rail, mounting plate, double flange roller, pivot pin assembly, U-shaped frame, safety pin, bolt and nut
Assembly, handle hole, upper limit plate, upper pillar stand, installing hole, elastic steel bar and spilled water hole.It is characterized in that: bottom plate is with welding
Mode is fixed on the top of lower pillar stand, and lower limiting board is welded on bottom plate, and convolution guide rail is to be welded or bolted nut fastening
Mode be arranged on bottom plate, upper limit plate with convolution guide rail be one；Mounting plate is welded on the bottom of upper pillar stand, U-shaped
Frame and mounting plate are one, and double flange roller is arranged on the endoporus of U-shaped frame by Assembly of pin, and safety pin is arranged on U-shaped frame
Exit orifice on, elastic steel bar is separately mounted in mounting plate and the corresponding installing hole of bottom plate, and bolt and nut component is arranged on
In the screwed hole of supporting plate, handle hole is opened in the side of upper pillar stand.
Release operation principle of the present utility model is as follows: in the case of calm or mild wind, elastic steel bar stably supports
Upper pillar stand and billboard, when fundamental wind pressure exceedes specification numerical value, elastic steel bar is produced by the pressure acted on billboard
Torsion, under the restriction of convolution guide rail and double flange roller, elastic steel bar is from bearing upper pillar stand and billboard weight transfers to and holding
Produced flexural deformation, at this moment, upper pillar stand and the centre-of gravity shift of billboard by moment of torsion, formed and increase elastic steel bar deforming torsional, this
Meaning that upper pillar stand and billboard tilt along the direction of wind-force, this result is exactly that the front face area of billboard reduces, wind
Power is the biggest, and the gradient of billboard is the biggest, and its front face area is the least.When wind-force disappears, the torsion on elastic steel bar
Effect also disappears, and elastic steel bar returns to erectility, and billboard naturally also returns to initial installment state.
Convolution guide rail and double flange roller define the movement locus of mounting plate and upper pillar stand, have been also subjected to Elastic Steel simultaneously
The positive and negative direction of rod and the side force in left and right direction.
The lower plane of mounting plate is equidistant with upper plane and the centre point of bottom plate, when billboard tilts, they
The joining of extended line is exactly the center of circle of elastic steel bar bending camber line, and centre point is the center of circle of convolution guide rail, at convolution guide rail
Under guiding, mounting plate does relative convolution relative to bottom plate with centre point for the center of circle and swings, and above structure eliminates Elastic Steel
Other additional stresses of rod so that it is work in the environment of pure torsion, extend the service life of elastic steel bar to the utmost.
Bolt and nut component can make up the various elastic steel bars caused due to the error making precision and installation accuracy and be subject to
The defect that power is uneven, can make weight be evenly distributed on every elastic steel bar by adjusting bolt and nut component, adjusts meanwhile
Bolt and nut component can make double flange roller effectively proper on the work surface of convolution guide rail, eliminates gap, it is to avoid collision, prolongs
Long convolution guide rail and the service life of double flange roller.
Safety pin can ensure that double flange roller keeps position accurately with convolution guide rail in good time, it is often more important that effectively shuts out
The situation that the double flange roller caused because of complicated blast and disorderly stress factor absolutely departs from convolution guide rail, it is ensured that device
Reliability.
The function of elastic steel bar is: when calm or mild wind, it is in erectility and stably supports upper pillar stand and wide
Accuse board.The elastic steel bar flexural deformation when wind speed reaches certain rank, and fundamental wind pressure exceedes specification numerical value.Lower limiting board and the upper limit
Position plate defines that elastic steel bar works in regime of elastic deformation.
Owing to upper pillar stand is connected formation confined space with mounting plate with welding manner, complete spiral shell by opening handle hole
The installation of bolt nut assembly and adjustment, spilled water hole can discharge the hydrops in the installing hole on bottom plate in time.
The beneficial effects of the utility model are: owing to have employed the principle of flexible release, enhance wind loading rating.Making
During the product of same wind resistance grade, it is possible to decrease the design intensity on billboard, column and basis, thus reduce product cost,
Saving steel, cement and manual resource.
