Description
Technical field
The utility model relates to a kind of scaffold anti-dumping anti-drop device, the anti-fall control device of particularly a kind of building operations attaching scaffold anti-dumping.
Background technology
In the high-building construction process, traditional console mode scaffold expends a large amount of metal material, and need to be equipped with more support body turnover material, and attaching scaffold can overcome above-mentioned these shortcomings well, thereby fire has reduced engineering cost greatly, this adheres to the ridge scaffold and has obtained using widely in increasing high-building construction, but the anti-tenesmus and the anti-inclination control of adhering to scaffold are the emphasis and the difficult point of support body elevating safety in the work progress, how reasonably to address this problem the key that becomes the safe handling attached lift scaffold.
At present, domestic existing many to research anti-fall, anti-tilt device, it as the patent No. 01262416 Chinese patent, the anti-fall dress a kind of net used for fishing of this attaching scaffold is equipped with the clamp retaining mechanism, form by clamp, pull bar, compression spring and spring base, the symmetrical distribution both sides, clamp connects by hinge pin, the inboard vertical rod of lifting false work places between the jaw of clamp, respectively there is a pull bar to be connected at the other end that must clamp with its hinge pin, draw to catch up with and fix a back-up ring fully, a compression spring and spring base are respectively arranged below back-up ring.Lower end at two pull bars connects a link rod, the middle part of link rod is connected with the suspension hook bar, the steel rope breaking that is connected with jacking equipment when scaffold, the suspension hook bar will not be subjected to the steel cable pulling force, effect at spring force is foretold, two clamps will turn over an angle, thereby clamp the inboard vertical rod of elevating mechanism, make elevating mechanism stop going up tenesmus, the weak point of this patent is: when the moment of wire cable rupture, lifting gear has tenesmus trend, only the elastic force with spring is difficult to guarantee that clamp clamps the inboard vertical rod of elevating mechanism, thereby the shortage reliability, and have only an anti-fall function, then make complex structure and each inter-agency cooperation that is difficult to if add anti-tilt device again; And for example the patent No. is 200820042267.7 Chinese patent, the electric up-down pin is in the anti-drop device of frame hoisting mechanism, form by assembly pulley, lever, spring, wedge, wedge cup etc., the operating principle of this device is: when the wire rope of hoisting scaffold disconnects suddenly, a pulley on the assembly pulley left side will lose the control of wire rope, under the effect of compression spring, the wedge jack-up that makes progress, and act on the wedge cup that matches, utilize the sawtooth of wedge internal orifice dimension, to embrace vertical rod, make that whole hoisting mechanism is unlikely to fall; The weak point of this patent is: structure is complicated, wedge relies on its frictional force to embrace the vertical rod of tenesmus and continuous whole scaffold thereof, when wedge makes progress jack-up under spring action when, vertical rod and continuous pin thereof give frame and begin tenesmus, under bigger frictional force effect, the elastic force of dependence spring is difficult in the instantaneous wedge item is played and subscribes the position, thereby wedge just can not clamp vertical rod fully, thereby lacks reliability.The weak point of existing attachment type raise scaffold anti-dumping, anti-drop device shows: anti-dumping, anti-drop device are separated, complex structure, and inter-agency cooperation requires high, relies on frictional force to clamp the vertical rod that is connected mutually with scaffold mostly, thereby lacks reliability etc.
Therefore, need the anti-fall control device of a kind of attaching scaffold anti-dumping, have simple in structurely, be easy to install, anti-dumping, anti-drop function are organically combined the characteristics that security reliability is high.
