Summary of the invention
Technical problem to be solved in the utility model is to provide for above-mentioned prior art a kind of anti-drop device of attachment type raise scaffold, and its elevating fall prevention separates use with the anti-fall Integral design that descends, and is highly sensitive, safe and reliable, and economic and practical.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the anti-drop device of attachment type raise scaffold, it is characterized in that including and be arranged on the attached wall girder steel at least one group by ways, the interlock anti-drop device that hoisting mechanism and safety dropping prevent mechanism form, described hoisting mechanism includes the lifting restoring spring and promotes suspension rod, wherein promote sheathed lifting restoring spring on the suspension rod, the top of lifting restoring spring is provided with the lifting upper padding plate, the below that promotes suspension rod is provided with electric hoist, safety dropping prevent mechanism includes anti-fall spring, gangbar, the adjustable supports push rod, described adjustable supporting support thick stick and promoting between the upper padding plate is connected by the gangbar that is arranged on adjustable supporting support thick stick one side, and anti-fall spring is positioned at the opposite side of adjustable supports push rod and links to each other with anti-fall backing plate on being arranged on the attached wall girder steel with the adjustable supports push rod.
Press such scheme, link to each other by being arranged on the connection cord that promotes upper padding plate between described many group interlock anti-drop devices.
Press such scheme, described ways is comprised of telescopic steel termination and the directive wheel that is hinged on the steel termination, described directive wheel is used for matching with the vertical gathering sill of scaffold vertical main framework both sides, and be embedded in the vertical gathering sill in the mode that can vertically slide, do not tilt to guarantee the support body vertical lifting.
Press such scheme, described connection cord adopts regulable ring-shaped hook in the hook portion that promotes the upper padding plate two ends, to guarantee the connection cord normal operation in the pre-buried deviation that allows.
Press such scheme, adopt the inner sleeve screwed connection between the first segment of described adjustable supports push rod and the second section, reach the needs of regulating length.
The utility model has the advantage of:
1) lifting member of the present utility model, anti-fall member and ways all are attached on the attached wall girder steel, and can be separated from each other between hoisting mechanism, safety dropping prevent mechanism and guiding mechanism and the attached wall girder steel, ways can be by the flexible certain length in the telescopic adjustment hole on the girder steel, to adapt to the building privileged sites, so that whole Hoisting System is flexible and changeable;
2) use anti-fall can the separating of the anti-fall and decline state of lifting state of the present utility model, hoisting mechanism can not installed the lifting restoring spring during lifting, anti-fall performance when as long as the service behaviour of the anti-fall spring of assurance can guarantee the support body lifting, Integral design separately uses simple and fast in practical operation, reduce intermediate link, improved operating efficiency;
3) anti-drop device that all arranges on the multiple tracks girder steel of the present utility model, fall device makes the anti-drop device synchronous working of three road girder steels by connection cord, and is not only highly sensitive, and support body is more safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model, and its medi-spring is in compressive state;
Fig. 2 is structural representation of the present utility model, and its medi-spring in the raw.
The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing, but this explanation can not consist of restriction of the present utility model.
Shown in Fig. 1-2, the anti-drop device of attachment type raise scaffold, include and be arranged on three groups of interlock anti-drop devices that formed by ways, hoisting mechanism and safety dropping prevent mechanism on the attached wall girder steel 1 of fixing with building, attached wall girder steel 1 is the gusseted structure, the installing hole that a strip is arranged on it, built-in fitting is fixed on the attached wall girder steel on the building by this installing hole.Described hoisting mechanism includes lifting restoring spring 8 and promotes suspension rod 9, wherein promote sheathed lifting restoring spring and the high-strength steel sleeve 7 that is arranged on its outside on the suspension rod, the top of lifting restoring spring is provided with and promotes upper padding plate 17, the below is provided with and promotes lower bolster 2, the below that promotes suspension rod is provided with electric hoist 5, link to each other by being arranged on the connection cord 14 that promotes upper padding plate between many group interlock anti-drop devices, connection cord adopts regulable ring-shaped hook in the hook portion that promotes the upper padding plate two ends, to guarantee the connection cord normal operation in the pre-buried deviation that allows, connection cord 14 lower ends can also be connected with adjustable suspension ring 15; Safety dropping prevent mechanism includes anti-fall spring 10, gangbar 11, adjustable supports push rod 12, be connected by the gangbar that is arranged on adjustable supporting support thick stick one side between described adjustable supports push rod and the lifting upper padding plate, adopt the inner sleeve screwed connection between the first segment of adjustable supports push rod and the second section, reach the needs of regulating length, anti-fall spring is positioned at the opposite side of adjustable supports push rod and links to each other with anti-fall backing plate 3 on being arranged on the attached wall girder steel with the adjustable supports push rod, described ways is comprised of telescopic steel termination and the directive wheel 6 that is hinged on the steel termination, be provided with adjustable guide extension hole 16 on the telescopic steel termination, described directive wheel is used for matching with the vertical gathering sill of scaffold vertical main framework 4 both sides, and be embedded in the vertical gathering sill in the mode that can vertically slide, do not tilt to guarantee the support body vertical lifting.
