The motion principle of blocking protection device for electric rolling door provided by the utility model：
As shown in figure 1, one end of rotating shaft 100 is connected with power motor 202, driven gear 404 and electric rolling door
On spool gears be connected, as shown in figure 3, electric rolling door decline when rotating shaft 100 rotation direction, power motor 202
Drive shaft 100 rotates, and rotating shaft 100 drives driving revolving drum 303 and driven rotating cylinder 403 to rotate in same direction together, driven gear 404 with
Spool gears on electric rolling door are connected, so the rotation direction of the two when electric rolling door declines process on the contrary, meet
To obstruction, the door piece on electric rolling door stops operating, while driven gear 404 and driven rotating cylinder 403 also stop operating, power
Motor 202 drives rotating shaft 100 and driving revolving drum 303 rotating, the first double wedge 3031 and driven rotating cylinder in driving revolving drum 303
The second double wedge 4031 on 403 alternates distribution, now, as shown in Fig. 2 the first double wedge 3031 is to 4031 turns of the second double wedge
It is dynamic, because the first double wedge 3031 rotates, the inclination flank of tooth of the inclination flank of tooth 3032 of the first double wedge 3031 along the second double wedge 4031
4032 slide, and the first double wedge 3031 moves along second slideway 4034, depart from described first to second double wedge 4031
Slideway 3034 simultaneously supports first double wedge 3031, i.e. the top of the double wedge 4031 of the top flank of tooth 3033 and second of the first double wedge 3031
Portion's flank of tooth 4033 contacts with each other, because driven rotating cylinder 403 can not move in rotating shaft 100, the inner tube wall of driving revolving drum 303 along its
Multiple strips the second lug boss (not shown) for replacing with multiple the first lug bosses of strip 101 and coordinating radially is equipped with, with
So that driven rotating cylinder 403 pushes driving revolving drum 303 to the side of headstock 201, now elastic component 302 to headstock 201 one
Side is compressed, and to cause the end thereof contacts of the one of transition disc 304 vertical side and connector 501, connector 501 can be touched spacing
Switch 502, and then start warning system 503, alarm is sent, the power supply of power motor 202 can be disconnected immediately so that power motor
202 stop operating, and realize and the door piece on electric rolling door is protected, and after barrier hinders elimination, will start power motor 202 once
After close, when starting power motor 202 once, rotating shaft 100 drives driving revolving drum 303 to rotate, driving wheel 301 and headstock 201
Between elastic component 302 reply the state before being compressed, driving revolving drum 303 is pushed back into the reset condition with driven rotating cylinder 403, with
So that the 3031 interlaced cooperation of the second double wedge 4031 and the first double wedge, is then shut off power motor 202, is again started up power electric
Machine 202 can normal use.
As shown in figure 4, when electric rolling door rises, the rotation direction of rotating shaft 100.
The application method of blocking protection device for electric rolling door provided by the utility model is as follows：
As shown in figure 3, electric rolling door decline when output shaft 100 rotation direction, power motor 202 drive output shaft
100 rotate, and rotating shaft 100 drives driving revolving drum 303 and driven rotating cylinder 403 to rotate in same direction together, driven gear 404 and electric rolling
Spool gears on door are connected, so the rotation direction of the two meets with obstruction on the contrary, working as electric rolling door and declining process, electricity
Door piece in dynamic rolling screen door stops operating, while driven gear 404 and driven rotating cylinder 403 also stop operating, the band of power motor 202
Turn axle 100 and driving revolving drum 303 are rotating, on multiple first double wedges 3031 in driving revolving drum 303 and driven rotating cylinder 403
Multiple second double wedges 4031 alternate distribution, now, the first double wedge 3031 as shown in Figure 2 rotates to the second double wedge 4031,
Because the first double wedge 3031 rotates, the inclination flank of tooth 4032 of the inclination flank of tooth 3032 of the first double wedge 3031 along the second double wedge 4031
Slide, the first double wedge 3031 moves along second slideway 4034, departs from first slideway to second double wedge 4031
3034 and first double wedge 3031 is supported, i.e. the top tooth of the double wedge 4031 of the top flank of tooth 3033 and second of the first double wedge 3031
Face 4033 contacts with each other, and because driven rotating cylinder 403 can not move in rotating shaft 100, the inner tube wall of driving revolving drum 303 is radially
Multiple strips the second lug boss (not shown) for replacing with multiple the first lug bosses of strip 101 and coordinating is equipped with, to cause
Driven rotating cylinder 403 pushes driving revolving drum 303 to the side of headstock 201, now side quilt of the elastic component 302 to headstock 201
Compression, to cause the end thereof contacts of the one of transition disc 304 vertical side and connector 501, connector 501 can touch limit switch
502, and then start warning system 503, alarm is sent, the power supply of power motor 202 can be disconnected immediately so that power motor 202
Stop operating, realize and the door piece on electric rolling door is protected, after barrier hinders elimination, after power motor 202 will be started once
Close, when starting power motor 202 once, rotating shaft 100 drives driving revolving drum 303 to rotate, driving wheel 301 and headstock 201 it
Between elastic component 302 reply the state before being compressed, driving revolving drum 303 is pushed back into the reset condition with driven rotating cylinder 403 so that
The 3031 interlaced cooperation of the second double wedge 4031 and the first double wedge is obtained, power motor 202 is then shut off, is again started up power motor
202 can normal use.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
