Abstract
The invention discloses a protection device for an electric rolling door, relating to the field of additional devices of electric rolling doors and solving the problems that: when the conventional electric rolling door usually used by people descends, because the situations that an inner door is opened outwards, obstacles are under the door, a door body and a door groove are blocked, and the like due to inattention of operation frequently appear and are not found in time, a rolling shaft continuously rotates to cause a door plank to be damaged or fixed points of the door plank and the rolling shaft to fall off, and the like. The protection device for the electric rolling door comprises a limit switch, wherein a microswitch is arranged on a lower limit control line of the limit switch; the microswitch is connected with a lower limit switch of the limit switch in series; and a circuit is in an off state when a key of the microswitch is pressed. By using the protection device for the electric rolling door, the phenomenon that the door body of the electric rolling door is damaged because the door body of the electric rolling door meets obstacles in the descending process to cause misoperation is fundamentally eliminated, and the service life of the electric rolling door is prolonged. The protection device disclosed by the invention has the advantages of simple structure, low cost, convenience for operation and debugging and operation reliability.
Description
Technical field
The present invention relates to a kind of attachment device of electric rolling door, particularly relate to the safety guard in a kind of electric rolling door descending stroke.
Background technology
At present, the normally used electric rolling door of people all is provided with upper limit position switch and lower position switch.When practical operation, do not note in the electric rolling door descending stroke if be especially at closing time, often have inside door and meet the situation appearance such as barrier, Men Tiyu gate slot are stuck to external-open, door are lower, in time do not find again, the fixing point that is rotated further with regard to causing door-plate damage or door-plate and spool of spool comes off like this, until spacing the putting in place of closing the door just can be cut off afterwards.This moment, the Men Tiyi of electric rolling door was damaged, repaired particularly troublesomely, and maintenance cost is also very high, therefore caused certain economic loss to the user.
Summary of the invention
The objective of the invention is provides a kind of safety guard in the electric rolling door descending stroke in order to overcome deficiency of the prior art.
For achieving the above object, the invention provides a kind of protection device for electric rolling door, comprise limit switch, be provided with sensitive switch on the lower limit control circuit of described limit switch, described sensitive switch is connected with the lower position switch of described limit switch; Described sensitive switch is fixed in the door guide groove top and under the spool of described electric rolling door of described electric rolling door.
Described sensitive switch is fixed in a guide groove top and the position under the spool of described electric rolling door is, 1-6 centimeters under the outer door sheet after quilt was rolled up in fact on the described spool after the spool of described electric rolling door and Men Tijuan were real.
Described sensitive switch is fixed in a guide groove top and the position under the spool of described electric rolling door is, 2-4 centimeters under the outer door sheet after quilt was rolled up in fact on the described spool after the spool of described electric rolling door and Men Tijuan were real.
Described sensitive switch is fixed in a guide groove top and the position under the spool of described electric rolling door is, 3 centimeters under the outer door sheet after quilt was rolled up in fact on the described spool after the spool of described electric rolling door and Men Tijuan were real.
Circuit is off-state during the button pressurized of described sensitive switch.
Described sensitive switch number is set to two, is series connection.
The sensitive switch of described two series connection is fixed on the link rod, and described link rod is fixed in a position on guide groove top and is, 1-6 centimeters under the outer door sheet after quilt was rolled up in fact on the described spool after the spool of described electric rolling door and Men Tijuan were real.
Be provided with limiting card on the bottom girder of described electric rolling every body, corresponding with described link rod.
Beneficial effect of the present invention is: use door body that protection device for electric rolling door of the present invention fundamentally stopped electric rolling door in descending stroke because the damage phenomenon that chance barrier or misoperation cause increases the service life; Simple in structure, with low cost, the operation debugging is convenient, reliable.
Below in conjunction with accompanying drawing protection device for electric rolling door of the present invention is described further.
Description of drawings
Fig. 1 is embodiments of the invention 1 protection device for electric rolling door structural representations;
Fig. 2 is embodiments of the invention 2 protection device for electric rolling door structural representations;
Fig. 3 is embodiments of the invention 3 protection device for electric rolling door structural representations.
Among the figure: 1, sensitive switch, 2, link rod, 3, spool, 4, limit switch, 5, upper limit position switch, 6, lower position switch, 7, the door sheet, 8, the door guide groove.9, door bottom girder, 10, limiting card, 11, motor.
Embodiment
Embodiment 1 as shown in Figure 1, two sensitive switch 1 series connection, these two sensitive switches 1 are also connected with the lower position switch 6 of limit switch 4 simultaneously, sensitive switch 1 is fixed on the link rod 2, the position that link rod 2 is fixed be the outer door sheet 7 of the spool 3 of electric rolling door after real by volume on the spool 3 after real with Men Tijuan under the 1-6 centimeters, the suitableeest is the 2-4 centimeters, and optimum is 3 centimeters.Circuit is off-state during the button pressurized of sensitive switch 1.Be provided with limiting card 10 on the bottom girder 8 of electric rolling every body, corresponding with link rod 2.When electric rolling every body falls to running into obstacle, if sensitive switch 1 is not installed as stated above, and in time do not find, because remaining in operation, spool 3 comes off with regard to the fixing point that causes door-plate damage or door-plate and spool, until spacing the putting in place of closing the door just can be stopped afterwards, but this moment, the Men Tiyi of electric rolling door was damaged, repaired particularly troublesome.Yet press present embodiment sensitive switch 1 is installed, then when electric rolling every body falls to running into obstacle, cause the door sheet 7 and spool 3 loosening supports greatly of a body this moment owing to the rotation of rotating shaft 3, the door sheet 7 that just occurs under the rotating shaft 3 can be pressed on the sensitive switch 1 that arranges under the spool 3, so just the circuit of lower limit is disconnected, motor 11 stops operating, can not occur causing the fixing point obscission of door-plate damage or door-plate and spool because spool 3 remains in operation, open upper limit position switch 5 circuit of the door that rises this moment, after Men Tiyu spool 3 volumes were real, sensitive switch 1 is pressurized and recover the normal power-up state no longer.Be provided with limiting card 10 on the bottom girder 8 of electric rolling every body, when limiting card 10 moved to link rod 2, then link rod 2 had just stoped the bottom girder 8 that is provided with limiting card 10 to continue motion, has therefore also further effectively protected the door body, is not damaged.
