Description
Technical field
The utility model relates to a kind of accessory structure of integral lifting scaffold, especially when rising or descend, drives the anti-fall eccentric wheel structure of integral lifting scaffold that anti-fall eccentric wheel and vertical main frame disengage at integral lifting scaffold.
Background technology
At building field; Especially middle-high building; In construction, extensively adopt integral lifting scaffold (climbing frame); The setting that matches with anti-tilt device and anti-drop device of its vertical main frame prevents that vertical main frame from tilting (deflection) and down fall, and prevents that integral lifting scaffold from producing security incident.In the prior art; Be called " attachment type raise scaffold ", application number in name and be in 00222196.6 the utility model patent file; Disclose a kind of by between monolithic welding, sheet and the sheet with the scaffold of the main frame of the typing chip trussed construction of bolted on connection and the typing chip trussed construction that uses in pairs; And with supporting and anti-fall anti-tilt device is connected with body of wall a plurality of adhering to; And the integral lifting scaffold formed such as electric block, anti-fall push rod, its anti-fall push rod relies on the elastic force of back-moving spring, and the top is stuck in the anti-fall tooth of main frame guide rail side; Anti-fall push rod prevents in the anti-fall tooth that through withstanding on the main frame guide rail from toward lower slider, preventing that whole scaffold from down falling.The deficiency of this kind scaffold; At first be to adopt anti-fall push rod to withstand in the anti-fall tooth of main frame guide rail and limit (preventing) main frame and fall; To having relatively high expectations of anti-fall tooth, anti-fall push rod; In most cases because of the fracture of anti-fall tooth or anti-fall push rod, perhaps anti-fall push rod can not in time reset and withstand anti-fall tooth and whole scaffold is down fallen, and produces security incident; Secondly, when the main frame guide rail rose under electric block drives or descends, when especially descending, anti-fall push rod shifted out inconvenience in anti-fall tooth, troublesome poeration; Once more, because high-rise, super highrise building more and more, and the performance of integral lifting scaffold etc. has been proposed requirements at the higher level, need prior art constructions further be improved, and could satisfy its security performance, could adapt to the needs of safe construction.
Summary of the invention
The utility model provides the anti-fall eccentric wheel structures of integral lifting scaffold that a kind of security performance is better, adapt to high level, construction of super highrise building needs to the integral lifting scaffold aforementioned deficiency in the morning of prior art.
The technical scheme of the utility model, the anti-fall eccentric wheel structure of integral lifting scaffold comprises vertical main frame, attached wall supporting frame and the anti-fall eccentric wheel of integral lifting scaffold, vertical main frame and anti-fall eccentric wheel are equipped with; It is characterized in that: all correspondence sets an anti-fall gangbar in anti-fall eccentric both sides, and the other end of two anti-fall gangbar is connected on the transverse axis respectively turnably; On two horizon bars of attached wall supporting frame, correspondence is provided with chute, and the two ends of transverse axis all are arranged in the chute, can be in chute move left and right; On transverse axis, be provided with fleet wheel, steel cable passes rope pulley, when steel cable is stressed, can drive transverse axis and in chute, move; On transverse axis, be provided with preloading spring, preloading spring is given spring force of transverse axis.
Further characteristic: an end of said anti-fall gangbar is to be connected on the anti-fall eccentric wheel through pin.
Two ends at transverse axis all are provided with preloading spring.
The anti-fall eccentric wheel structure of the utility model integral lifting scaffold with respect to prior art, has following characteristics:
1, the structure that adopts eccentric wheel to cooperate with vertical main frame, in the main frame Shi Gengneng increase clamping force of down falling, clamping tightlier stops falling main frame, plays extraordinary security protection effect.
2, scaffold can make things convenient for, reliably the eccentric wheel backward rotation unclamped main frame when descending, and main frame can descend under slave mode.
3, the elastic force of two preloading springs about, through transverse axis with about two anti-fall gangbar act on the anti-fall eccentric wheel, make anti-fall eccentric wheel and vertical main frame keep excellent contact, also can improve safety.
4, can adapt to high level, construction of super highrise building needs.
