Abstract
The utility model discloses a position limitation protecting device for a door body of an electric rolling door, which relates to the field of protecting devices for electric rolling doors and aims to solve the problem that the door body is damaged because of being excessively turned and rolled in the ascending process of the electric rolling door generally used by people at current and the like. The electric rolling door of the position limitation protecting device for the door body of the electric rolling door comprises a motor, wherein the motor is provided with a limiting switch; an upper limit control circuit of the limiting switch is provided with a micro switch; the micro switch is fixed on the lower end surface of a top plate of the electric rolling door and positioned right above a rolling shaft of the electric rolling door; a stop lever is fixedly arranged below the rolling shaft and at the upper part of a door guide slot; and the inner side of a bottom door beam is fixedly provided with a limiting plate. The position limitation protecting device for the door plate of the electric rolling door, disclosed by the utility model, is simple in structure, low in cost, convenient to mount as well as safe and reliable.
Description
Technical field
The utility model relates to a kind of electric rolling every body protective device, particularly relates to a kind of electric rolling every body limiting and protecting device.
Background technology
At present, all be provided with upper limit position switch and lower position switch on the normally used electric rolling door motor of people, this door body according to the rules stroke in running that has guaranteed to a certain extent electric rolling door carries out lifting, but run into motor according to the rules stroke turn round particularly that motor continuous service occurs and can not in time find in up process, so then easily cause the door body of electric rolling door to damage, repair particularly troublesome, maintenance cost is also very high, therefore cause certain economic loss to the user, also affect the user to the normal use of electric rolling door simultaneously.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of simple in structure, with low cost, easy for installation and safe and reliable electric rolling every body limiting and protecting device to be provided.
For achieving the above object, the utility model provides a kind of electric rolling every body limiting and protecting device, described electric rolling door comprises motor, spool, door sheet, door guide groove, door top board and door bottom girder, be provided with limit switch on the described motor, described limit switch includes upper limit position switch and lower position switch, be provided with microswitch on the upper limit control circuit of described limit switch, described microswitch is connected with the upper limit position switch of described limit switch; Described microswitch be fixed in described electric rolling door the door top board the lower surface on and directly over the spool of described electric rolling door; The top of the below of described spool and door guide groove is fixedly installed pin; The inboard of described door bottom girder is fixedly installed limiting plate.
Described microswitch be fixed in a top board the lower surface and the position directly over the spool of described electric rolling door be the spool of electric rolling door and the Men Tijuan outermost layer door sheet after real by volume on the described spool after real directly over 3 centimeters.
The fixing limiting plate in inboard of described door bottom girder is provided with two.
The utility model beneficial effect is: use electric rolling every body limiting and protecting device of the present utility model simple in structure, with low cost, easy for installation; The door body that has fundamentally guaranteed electric rolling door can not cause because motor is out of control the door body of electric rolling door damaged in upward stroke, exempt the door body and excessively caused because overturning damaging the maintenance work that to carry out, greatly prolonged the application life of electric rolling door.
Below in conjunction with accompanying drawing electric rolling every body limiting and protecting device of the present utility model is described further.
Description of drawings
Fig. 1 is the positional structure schematic diagram in electric rolling door of the present utility model.
Among the figure: 1, motor, 2, spool, 3, the door sheet, 4, the door guide groove, 5, the door bottom girder, 6, limit switch, 7, upper limit position switch, 8, lower position switch, 9, microswitch, 10, the door top board, 11, limiting plate, 12, pin.
The specific embodiment
As shown in Figure 1; the electric rolling door of electric rolling every body limiting and protecting device of the present embodiment comprises motor 1, spool 2, door sheet 3, door guide groove 4, door top board 10 and door bottom girder 5; be provided with limit switch 6 on the motor 1, limit switch 6 includes upper limit position switch 7 and lower position switch 8.Be provided with microswitch 9 on the upper limit control circuit of limit switch 6, microswitch 9 is connected with the upper limit position switch 7 of limit switch 6, microswitch 9 be fixed in electric rolling door the door top board 10 the lower surface on and directly over the spool 2 of electric rolling door.Microswitch 9 be fixed in the lower surface of a top board 10 and in the position directly over the spool 2 of electric rolling door be the spool 2 of the electric rolling door outermost layer door sheet 3 after real by volume on the spool 2 after real with Men Tijuan directly over 3 centimeters.The top of the below of spool 2 and door guide groove 4 is fixedly installed pin 12.The inboard of door bottom girder 5 is fixedly installed limiting plate 11, and the fixing limiting plate 11 in inboard of door bottom girder 5 is provided with two.
If after motor 1 drives spool 2 runnings so that the up predetermined stroke above upper limit position switch 7 of door body, if then can be blocked by door guide groove 4 fixing limiting plates 11 by limiting plate 11 fixing on the door bottom girder 5 predetermined stroke above upper limit position switch 7 when the door body is up on the one hand, can effectively stop a body to continue up and damaged, if on the other hand the fixing microswitch 9 in door top board 10 lower surfaces when the door body is up, surpass upper limit position switch 7 predetermined stroke then by spool 2 on the door sheet 3 of the superiors push down and so that the upstream circuitry of motor 1 disconnects, also can effectively stop a body to continue up and damaged.
