Abstract
The invention provides a high-strength anti-flooding protection door which consists of reinforcing slideways on the two sides, panels on the two sides of the protection door, an inclined plane reinforcing plate, roll bearings and a lower pressure shaft, wherein the inclined plane reinforcing plate is arranged between the panels on the two sides; scarf welding is adopted for reinforcing to form a stable triangular structure; the roll bearings are fixed on the surfaces on the two sides of the door, and move along the reinforcing slideways; and the triangular stable structure of the protection door has good tension and stress resistance, can bear the pressure difference of the water depth of 50-100m, and is applied to the tunnels under the river, underground mines, ultra-deep subways and the like.
Description
Technical field
The present invention relates to protective door, especially protective door structure.
Background technology
Present protective door has manual closed and motorized motions.Automatically controlled protective door mainly is used in the civil air defense constructions and installations access that requires automaticity higher.Divide automatically controlled airtight blast door, automatically controlled sealed door, automatically controlled airtight shield door and automatically controlled protective door four big classes, shield door has the radioactive contamination of prevention, engineering inside and two kinds of functions of tempest are infiltrated in biological and chemical war agent.
But mostly present protective door is single steel plate structure; Anti-strike capability when hitting for the bigger or bomb of impact force like this is lower, meet high-strength impact after, the door easy deformation; Be not easy to open the escape when influence leaving behind all clear and capturing with inside.
Especially subway, tunnel or mine etc. are lower than the place of face of land water level, cause catastrophic effect easily.
Summary of the invention
The invention provides the anti-protective door structure that floods of a kind of high strength.
Technical scheme is following:
A kind of high strength flood and preventive door; It is characterized in that forming by both sides reinforcing slideway, protective door both sides panel, inclined-plane gusset plate, rolling bearing, following last item; Be the inclined-plane gusset plate between the panel of both sides, adopt the inclined-plane reinforcement of weld, form stable triangular structure; Rolling bearing is fixed on a both side surface, moves along reinforcing slideway.
The triangle rock-steady structure of protective door like this has good tension force and anti-pressure ability, can bear the pressure differential of the 50-100 rice depth of water.
Description of drawings
Accompanying drawing is a structural plan of the present invention sketch map.
Wherein: 1, reinforce slideway; 2, rolling bearing; 3, the inclined-plane gusset plate; 4, the protective door side panel.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified: protective door is made up of two side panels 4 and inclined-plane gusset plate 3, and door reduces friction with the reinforcing slideway 1 middle rolling bearing 2 that is provided with.Protective door is made up of stable triangle like this, has good anti-pressure ability.
In practical implementation, also have following preferred version:
1. gusset plate along continuous straight runs in inclined-plane is reinforced, and can pass to power the wall of both sides when being hit like this, is fit to sealing in various degree, impacts damaging when avoiding closing the door action.
2. rolling bearing adopts the roller bearing.
3. the two ends of protective door are provided with automatic closed watertight circle, and structure and high-pressure cooker sealing ring are similar, adopt inverted U-shaped plastic cement strip of paper used for sealing.
Adopt protective door of the present invention, can resist the compressive resistance of 50-100 rice, be applied to river-crossing tunnel, underground mine, ultra dark subway etc.
Claims (4)
1. high strength flood and preventive door; It is characterized in that forming by both sides reinforcing slideway, protective door both sides panel, inclined-plane gusset plate, rolling bearing, following last item; Be the inclined-plane gusset plate between the panel of both sides, adopt the inclined-plane reinforcement of weld, form stable triangular structure; Rolling bearing is fixed on a both side surface, moves along reinforcing slideway.
2. high strength flood and preventive door as claimed in claim 1 is characterized in that inclined-plane gusset plate along continuous straight runs reinforcing.
3. high strength flood and preventive door as claimed in claim 1 is characterized in that rolling bearing adopts the roller bearing.
4. high strength flood and preventive door as claimed in claim 1 is characterized in that the two ends of protective door are provided with automatic closed watertight circle, adopts inverted U-shaped plastic cement strip of paper used for sealing.
