Description

The anti-fall scaffold device of integral elevating

The utility model relates to highrise building and uses the scaffold field, the anti-fall scaffold device of specifically a kind of integral elevating, and particularly suitable is at the main body construction of highrise building and carry out decoration of exterior wall.

High speed development along with urban construction, for adapting to the needs of high-building construction, a kind of " flying scaffold that has elevating mechanism " technology has appearred in building trade, because it can save a large amount of scaffold steel frame material for building, greatly reduce the building operations cost, in high-building construction, obtain application more and more widely.But modal a kind of liftable flying scaffold is to be formed by a plurality of unit combination that are distributed in the skin independent-lifting, this scaffold is visited and is made comparatively trouble, and the globality of scaffold and less stable, in high-building construction, lack the enough sense of security, in use be subjected to certain limitation.Chinese patent: CN2187637Y discloses the utility model that a kind of name is called " electric up-down integral-scaffold ", it is mainly by the scaffold on the bearing support that is located in many group elevating mechanisms, directive wheel, the support bracket that is fixed in skin constitutes, the electric block that each bearing support is hung respectively on the support bracket of its place group is hung, the electric block synchronization lifting of elevating mechanism is respectively organized in control, integral-scaffold rises or descends when putting in place, each bearing support links to each other with the set bolt that is through at skin through the attached wall pull bar, integral-scaffold can be stable in skin, its weight commentaries on classics is born by skin, when rising or decline integral-scaffold, need unclamp earlier and be through at the set bolt that bearing support is respectively organized in the skin connection, starting electric block more synchronously gets final product, though this " electric up-down integral-scaffold " has the mechanization degree height, easy to operate, the advantage that resistance to overturning is good, but in rising or decline integral-scaffold process, owing to unclamped the set bolt of respectively organizing bearing support, at this moment the total weight of integral-scaffold is born by the electric block of hanging on support bracket, just in case the fracture of electric block chain appears in integral-scaffold in process of rising or falling or other damages phenomenon, the serious accident that will cause unsettled integral-scaffold disequilibrium and tilt even fall, consequence is with hardly imaginable.

The purpose of this utility model is to propose the anti-fall scaffold device of a kind of improved integral elevating on the basis of existing technology; it has chain rupture anti-falling protection measure in integrated stand ascending, descending process; can prevent the serious accident that integrated stand tilts even falls effectively, very high security performance is arranged.

The purpose of this utility model is achieved by the following technical solution.

The anti-fall scaffold device of a kind of integral elevating, it mainly by be located in integrated stand on many group load pallets, be connected in integrated stand guide rail, place on the guide rail and be fixed in the directive wheel of skin, encorbelment beam and the electric block that is fixed in skin constitutes, each load pallet is hung by electric block respectively; Encorbelment and be fixedly connected with take-up housing on the beam, the load bar lower end of passing the take-up housing through hole is connected with otic placode and is supported by the force bearing plate that is connected in the pallet boatswain chair, the shackle of being inserted in the pallet suspension ring is connected in the otic placode of load bar lower end, the end hinge joint that is supported in the lever of take-up housing has slider wedge, slider wedge inserts and is installed with in the take-up housing through hole of load bar, the screw rod of secondary suspension ring passes spring by regulating fixed by nut in the other end of lever, the suspension hook of electric block is striden the main suspension ring of wearing secondary suspension ring and being connected in the beam of encorbelmenting simultaneously, just in case occur chain fracture or other damage of electric block in the process that integrated stand is rising or descending, integrated stand has the trend that tilts to fall, at this moment, because the suspension hook weightlessness of electric block, spring is compressed the elastic potential energy of being put aside secondary suspension ring is pulled upwardly, the screw rod of secondary suspension ring upwards holds up an end of lever, the slider wedge that the downward rapidly promotion of the other end of lever is linked, slider wedge moves downward along the take-up housing through hole, slider wedge produces normal pressure to the load bar that penetrates in the take-up housing through hole, form the drag friction resistance that enough stops the load bar to glide, clamp the load bar; By the shackle of being inserted in the pallet suspension ring and being connected in the otic placode of load bar the load pallet is held; thereby the serious accident that the integrated stand that can prevent located load pallet tilts to fall; the through-hole wall of slider wedge, take-up housing has been done screw thread; can clamp the load bar well, anti-falling protection effect is preferably arranged.

The utility model is the otic placode with the load bar penetrates in the through hole of the take-up housing that is connected in the beam of encorbelmenting, the shackle of being inserted in the pallet suspension ring is connected in load bar lower end, just in case electric block chain rupture or other damage appear in integrated stand in the ascending, descending process, clamp the load bar by the slider wedge that links in lever one end, can prevent effectively that integrated stand from tilting to fall, and has high security performance.
