Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Referring to figs. 1 through Fig. 6, the embodiment of the present invention provides a kind of attachment type raise scaffold anti-drop device, comprise attached wall support, attached wall support comprises two block plates 11 that are parallel to each other, one side of two block plates 11 connects attached wall end plate 12, support body location supporting rod is installed above steel plate 11, and the bottom of support body location supporting rod is installed on the top of two block plates 11 by bearing pin 3; Support body location supporting rod comprises end cover 21, adjusting screw(rod) 22 and top 23, top 23 is provided with stopper slot 24, adjusting screw(rod) 22 one end spinnings are in end cover 21, the other end of adjusting screw(rod) 22 stretches out end cover 21 spinning top 23, between end cover 21 and top 23, be provided with hold-down nut (not shown in FIG.), the bottom of end cover 21 is installed on the top of steel plate 11 by bearing pin 3.
Outside at two block plates 11 is equipped with guide type shoe, guide type shoe comprises the fixing channel-section steel 41 of horizontally set, on fixing channel-section steel 41, be arranged with movable channel-section steel 42, fixing channel-section steel 41 has corresponding perforate with on movable channel-section steel 42, and movable channel-section steel 42 is bolted to connection in fixing channel-section steel 41; The front end of movable channel-section steel 42 stretches out steel plate 11 and arranges, and connect roller 43 in the front end inner side of movable channel-section steel 42, vertical guide rail is housed on roller 43, between the rail body 51 that guide rail is arranged by bilateral symmetry and two rail bodies 51, uniform anti-fall lever 52 is integrally formed structure, the outside of body 51 is provided with the strip groove 53 adapting with roller 43 in-orbit, roller 43 is placed in strip groove 53, and strip groove 53 can slide up and down by roller 43.
Catching device is equipped with in inner side at two block plates 11, catching device comprises symmetrically arranged two eccentric wheel discs 61, the spring 70 that passes on left of eccentric wheel disc 61 is connected with the below of attached wall end plate 12, make the setting that is inclined upwardly of eccentric wheel disc 61, between two eccentric wheel discs 61, be provided with deflection plectrum 62, eccentric wheel disc 61 adopts same rotating shaft 63 with deflection plectrum 62, below deflection plectrum 62, between two eccentric wheel discs 61, be provided with position-limitting pin 65, position-limitting pin 65 makes deflection plectrum 62 limited with respect to the deflection angle of eccentric wheel disc 61; Eccentric wheel disc 61 is selenodont, is crotch 611 in the left side of eccentric wheel disc 61, is stop part 612 on the right side of eccentric wheel disc 61, and spacing lever 64 is set above crotch 611, and spacing lever 64 is fixed between two block plates 11.In the time of eccentric wheel disc 61 clockwise deflection, the crotch 611 in eccentric wheel disc 61 left sides catches on spacing lever 64, thereby is subject to the restriction of spacing lever 64.
The using method of this attachment type raise scaffold anti-drop device is as follows:
(1) when guide type shoe is fixed, guide rail moves upward by roller 43, as shown in Figure 3, along with the upwards rectilinear motion of anti-fall lever 52, the end of deflection plectrum 62 is up with the neutral of anti-fall lever 52, and anticlockwise deflection occurs under the promotion of anti-fall pin 52, when anti-fall lever 52 is crossed behind the bottom of deflection plectrum 62, there is clockwise deflection in deflection plectrum 62, and repeat said process under the promotion of the anti-fall lever of the next one under the gravity of self, and guide rail moves upward smoothly.
(2) when guide type shoe is fixed, when guide rail moves downward by roller 43 low speed, as shown in Figure 5, the end of deflection plectrum 62 is placed between two adjacent anti-fall levers 52, because anti-fall lever 52 is less with the energy that the end collision of deflection plectrum 62 produces, deflection plectrum 62 can not trigger eccentric wheel disc 61 clockwise upset occurs, and guide rail is freely descending by roller.
(3) in the time there is the abnormal tenesmus of hanging in guide rail, guide rail acceleration falls, now the end of deflection plectrum 62 is subject to the outer impact of going all out of anti-fall lever 52, as shown in Figure 1 and Figure 4, because deflection plectrum 62 is limited with respect to the deflection angle of eccentric wheel disc 61, therefore touch eccentric wheel disc 61 significantly deflection of clockwise direction occurs, the stop part 612 on eccentric wheel disc 61 right sides is slipped between two adjacent anti-fall levers 52, the crotch 611 in eccentric wheel disc 61 left sides catches on spacing lever 64, be equivalent to insert row's brake bar between two adjacent anti-fall levers 52, and the crotch 611 of eccentric wheel disc 61 is also subject to the restriction of spacing pin 64, reach firm anti-fall object.
As can be seen from the above description, this attachment type raise scaffold anti-drop device simple in structure, there is no unnecessary being in transmission connection, be subject to outer impact of going all out by deflection plectrum 62 completely, and the braking of the gravity of eccentric wheel disc 61, safe and reliable, easily install, be convenient to Check and Maintenance maintenance, and prove through test of many times, brake anti-fall average distance between 20-60mm, meet the demands.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
