Abstract
The utility model relates to an it is little both to have had the resistance of opening, simple to operate, and usable gravity is realized compriseing the vertical ladder half space is from closing emergency exit of self -closing emergency exit base, commentaries on classics axle bolt, roof, steel pipe, bottom plate, construction bolt, baffle, door plant again, base, roof and bottom plate constitute the installation base and adopt the construction bolt fixed to the platform railing, and steel pipe, baffle and door plant constitute whole safe door plant and install on the base through changeing axle bolt. The advantage: firstly, simple structure, safety, practicality, secondly, it is little to open the resistance, and self -closing is realized to usable gravity.
Description
Technical field
The utility model relates to one and had both had that to open resistance little, easy for installation, gravity can be utilized again to realize the catladder half space self closing safety door of self-closing safety door, belong to large-sized storage tank ladder safety door and manufacture field.
Background technology
Because large-sized storage tank is higher to storage tank overhead height from ground, upper and lower ladder or escape ladder need be set, when ladder adopts catladder form, the danger of falling is had between interval platform and catladder, so half space place arranges self closing safety door in the middle of on catladder, ensure the safety of upper and lower personnel.Normally used exit structure is that pipe fitting curves and is squarely welded on platform railing with spring hinge, and shortcoming is people can only be with one-handed performance when opening safety door on catladder, and the comparison of resistance opening door is large, and on-the-spot overhead welding is also more dangerous in addition.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design one had both had that to open resistance little, easy for installation, and gravity can be utilized again to realize the catladder half space self closing safety door of self-closing safety door.
Design scheme: in order to realize above-mentioned purpose of design.Base, top board and base plate are welded into mounting seat, be fixed on platform railing with erection bolt again, again steel pipe, baffle plate (preventing the opened gravity that can not realize greatly of door-plate from closing) and door-plate are formed safe door-plate and be fixed in mounting seat by rotating shaft screw bolt, the object of such design is: the automatic closing function that can meet interval dock door place safety door, the weak point can fundamentally avoiding background technology to exist again.
Technical scheme: a kind of catladder half space self closing safety door, is made up of base, rotating shaft screw bolt, top board, steel pipe, base plate, erection bolt, baffle plate, door-plate; Base, top board and base plate form mounting seat and adopt erection bolt to be fixed on platform railing, and steel pipe, baffle plate and door-plate are formed general safety door-plate and be arranged on base by rotating shaft screw bolt.
The utility model is compared with background technology, and one is that structure is simple, safe, practical; Two is that to open resistance little, and gravity can be utilized to realize automatically closing.

Fig. 1 is the structural representation of catladder half space self closing safety door.
Fig. 2 is the top view of this structure.
Fig. 3 is the left view of this structure.
Detailed description of the invention
Embodiment 1: with reference to accompanying drawing 1.A kind of catladder half space self closing safety door, is made up of base 1, rotating shaft screw bolt 2, top board 3, steel pipe 4, base plate 5, erection bolt 6, baffle plate 7, door-plate 8; Base 1, top board 3 and base plate 5 form mounting seat and adopt erection bolt 6 to be fixed on platform railing, steel pipe 4, baffle plate 7 form general safety door-plate with door-plate 8 and baffle plate 7 is connected with steel pipe 4 and door-plate 8 respectively, and steel pipe 4 is arranged on base by rotating shaft screw bolt 2.Described mounting seat is π character form structure, and described door-plate 8 has multiple hole.Described baffle plate 7 is greater than 90 degree with the angle of door-plate 8, and object is convenient to door-plate 8 and is automatically closed under gravity, and its manufacture craft system prior art, is not described herein at this.
It is to be understood that: although above-described embodiment to be contrasted detailed text description to the utility model; but these text descriptions; just the simple text of the utility model mentality of designing is described; instead of the restriction to utility model mentality of designing; any do not exceed the utility model mentality of designing combination, increase or amendment, all fall in protection domain of the present utility model.
