Description
Technical field
The utility model relates to the improvement technology of high-building construction with guide bracket formula attached lift scaffold, is specifically related to a kind of energy and realizes vertical main frame and project subject spacing step-less adjustment, reduces the distortion of vertical main frame under various operating modes; The guide bracket formula attached lift scaffold of realizing the full-automatic anti-dropping of lifting process and having the underload defencive function in seat in the plane and can realize effectively reducing the overturning moment that frame structure produces in lifting process.
Background technology
As everyone knows, guide bracket formula attached lift scaffold mainly comprises the frame structure of being made up of the vertical main frame of support body, support body horizontal beam frame and support body framework; The adhering lifting system that forms by attached support structure, elevating mechanism and safety guard; And electrical control system three parts.Wherein, device attached support structures such as leading anti leaning equipment, falling proof device are installed on the attached support structure generally to be installed in the building structure by through-wall bolt, its effect is that frame structure can both be attached on the project subject (building) under any operating mode reliably, and with the various loading transfer of frame structure to building structure; Vertical main frame is provided with guide rail, is installed in the guide holder of leading anti leaning equipment, and guide rail can be moved up and down along guide holder.Under the work operating mode, frame structure generally is suspended on architecture enclosing by the gag lever post on the vertical main frame guide rail being shelved on the anti-fall plate on the falling proof device.The last suspension centre of elevating mechanism generally is installed on attached support structure or the project subject (building), and following suspension centre generally is contained on the leger of arranging in the support body or bottom support body, realizes lifting by jacking equipment.
At present, existing attached support structure device construction is roughly: attached support structure and leading anti leaning equipment are monolithic construction; Falling proof device form of structure is various, gets up mostly to be one-way ratchet and friction-type structure but conclude; Vertical main frame mostly is one-piece construction, and up-down mode adopts eccentric hoisting way of cable-stayed type or rectilinear eccentric hoisting way more.
Adhere to supporting arrangement and be designed to monolithic construction, have the problem of regulating difficulty with the guiding falling proof device.Generally speaking, adopt chock, parallels or the homemade part of increasing to regulate, this kind regulative mode is limited regulative mode, is difficult to satisfy the appropriate distance between support body and the project subject; And can cause overturning moment to increase, and also can't guarantee the straightness accuracy of the guide rail on the vertical main frame, cause vertical main frame to have very big Installation Stress, thereby the guide rail on the vertical main frame is deformed.Especially in lifting process,, lifting force is increased, have great potential safety hazard because the distortion of vertical main frame is big.
Falling proof device adopts one-way ratchet and friction-type structure, has following problem:
1, adopt detent mechanism, the disclosed ZL00222196.9 of Chinese patent " attachment type raise scaffold " for example, can realize the anti-fall of lifting process easily, but realize the anti-fall of the process of descending, the excitation apparatus that needs another set of artificial installation, its anti-fall excitation apparatus is by the flower basket bolt of adjustable length, quantitatively elongation pull bar and wire rope are formed, all need to rely on artificial assembling before each the downslide, after jacking equipment is stressed such as cucurbit, scaffold is promoted a segment distance, again by manually tightening up flower basket bolt, change and quantitatively extend the total length that pull bar and wire rope are formed, make the anti-fall tooth on the anti-fall lifter guide anti-fall, at this moment anti-fall excitation apparatus just works, and whole process operation is loaded down with trivial details, makes mistakes easily; Follow the line of least resistance such as the workman and directly to fix after anti-fall push rod left anti-fall tooth, falling proof device was lost efficacy, have great potential safety hazard with things such as iron wires.This technology causes the moderate finite deformation of vertical main frame and leading anti leaning equipment easily because the mode that adopts anti-faller side direction to shore makes vertical main frame and leading anti leaning equipment bear great horizontal component in addition, and influence is normally used.
2, the anti-fall braking of friction-type structure mainly realizes by the friction between punching pull bar surface and the brake block surface.Because the building operations environment is poor, its friction surface damages easily, causes brake failure.Its anti-fall principle is to utilize the lapse rate of support body to drive anti-fall, and brake area generation friction wedging is realized.This kind implementation just works after frame structure drops, and in whole process, anti-fall process lags behind relatively, and anti-fall distance is increased, and causes impact force big, has great potential safety hazard.
Vertical main frame adopts one-piece construction, and its rigidity is relatively poor, under the effect of overturning moment, be easy to generate the distortion of guide rail and support body, and this kind structure can not realize rectilinear center hoisting way, can only take eccentric hoisting way of cable-stayed type or rectilinear eccentric hoisting way.
The eccentric hoisting way of cable-stayed type produces bigger horizontal component, can cause the increase of lifting force; Because the existence of horizontal component also can produce great frictional force, thereby lifting force is further increased; The existence of horizontal component and frictional force makes frame structure be easy to generate plastic strain in lifting process and also can have bigger potential safety hazard.
Though rectilinear eccentric hoisting way does not have the existence of horizontal component, can produce extra moment of flexure; This moment of flexure is overcome by the counter-force of many assembly guidances, because the existence of the counter-force of guiding device can cause the frictional force in the lifting process, thereby required lifting force is increased, and excessive counter-force can make support body produce distortion and cause potential safety hazard.
