Embodiment
Describe the optimal technical scheme of the use of the new type in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model is a kind of dual fail-safe type attached type lifting scaffold inclining anti-fall device, including branch
Frame 1, joist steel upright 2, anti-tilt device 3, anti-fall device 4 and falling-prevention protecting device 5, the stent 1 are fixed on building, institute
Stating anti-tilt device includes guide grab 12 and side plate 13, is formed between two wing plates and web of joist steel upright 2 and is located at foot hand respectively
The vertical guide groove of column both sides is erected, guide grab 12 is provided with the guide groove, the guide grab 12 is fixed with side plate 13 to be connected
Connecing, side plate 13 is bolted to connection with the stent 1, and the fixed and positioned of anti-tilt device is easy in detachable design,
The guide grab 12 along guide groove in a manner of it can slide vertically in two guide grooves.
As shown in Figure 2, Figure 3 and Figure 4, the anti-fall device 4 is installed on 1 top of stent by third hinge axis 17, described
Third hinge axis 17 is cylindrical to be cased with the 3rd torsional spring 18, and anti-fall device 4 includes anti-fall mandril 14 and anti-fall sleeve 15, the anti-fall top
Connected between bar 14 and anti-fall sleeve by nut 23.The falling-prevention protecting device 5 includes insurance block 6, insurance plectrum 7 and the
One hinge axis 8, the insurance block 6 is L-shaped, is installed on the lower part of the stent 1 by first axle axis 8, and described first
Hinge axis 8 is cylindrical to be cased with the first torsional spring 9, and the insurance plectrum 7 is connected with the insurance block 6 by second hinge axis 10, institute
State that second hinge axis is cylindrical to be cased with the second torsional spring 11.
The application method of the dual fail-safe type attached type lifting scaffold inclining anti-fall device is as follows：
Anti-tilt device 3 is bolted on stent both sides, since the guide grab 12 of anti-tilt device 3 is embedded in joist steel upright
The recess of web between 2 liang of wing plates, during joist steel upright 2 lifts, the joist steel upright 2 is directed to pawl 12
Block, so can prevent that joist steel upright 2 is outward-dipping.
（1）When stent 1 is fixed on building, when joist steel upright 2 is moved upwards by guide grab 12, with support
Plate 16 moves upwards, and deflection clockwise occurs under the promotion of support plate 16 for anti-fall mandril 14, when anti-fall mandril 14 turns over necessarily
After angle, counterclockwise deflection can occur under the action of the 3rd torsional spring 18 and retract reset for anti-fall sleeve 15, and next
Repeated the above process under the promotion of support plate 16, joist steel upright 2 can be moved smoothly upwards；Similarly, with support plate 16 to
Upper movement, insurance plectrum 7 can also occur to deflect clockwise under the promotion of support plate 16, and insurance plectrum 7 passes through second hinge axis
10 and second the effect of torsional spring 11 drive safety dog block 6 to occur to deflect clockwise, connect due to insuring block 6 at this time with lever 20
Touch, lever 20 can hinder insurance block 6 to rotate clockwise, and therefore, the insurance plectrum 7 can be clockwise around 8 axis of first axle
Rotate, when turning to certain angle, generation can be produced under the action of the second torsional spring 9, and counterclockwise deflection retracts reset,
And repeated the above process under the promotion of next support plate 16, joist steel upright 2 can be moved smoothly upwards.
（2）When stent 1 is fixed on building, when joist steel upright 2 is normally moved downward by guide grab 12, due to
Anti-fall mandril 14 withstands the lower section of support plate 16, is at this time first lifted up joist steel upright 2 a bit, then pulls first to draw
Ring 19 rotates clockwise anti-fall mandril 14 so that anti-fall mandril 14 departs from the support plate 16 on joist steel upright 2, similarly, insurance
The second draw ring 21 is provided with plectrum 7, through hole 22 is provided with the insurance block 6, is to have drag-line on the draw ring, the drag-line
Through the through hole 22, pull the drag-line on falling-prevention protecting device 5 that insurance plectrum 7 is pulled away to the lower section of support plate 16, at this time, then
Moving downward joist steel upright 2 can normal operating.
（3）When abnormal drop occurs in joist steel upright 2, as support plate 16 moves downward, anti-fall mandril 14 withstands branch
The lower section of fagging 16 prevents joist steel upright 2 from dropping, and in the case that anti-fall device 4 fails, support plate 16 moves downward can be fast
Speed stirs insurance plectrum 7 so that insurance plectrum 7 is rotated counterclockwise so as to drive the insurance block 6 fast around first axle axis 8
Speed rotates counterclockwise, and insures block 6 upper end at this time and heads into the lower section of support plate 16 and stuck, thus prevent joist steel upright 2 after
Continuous tenesmus.
Specific embodiment of the utility model is described in detail above, but it is intended only as a kind of implementation therein
Example, the utility model are not restricted to particular embodiments described above.To those skilled in the art, it is any to this reality
With the new equivalent modifications carried out and substitute also all among the category of the utility model.Therefore, the utility model is not being departed from
Spirit and scope under the impartial conversion made and modification, should all cover in the scope of the utility model.
