Abstract
The utility model discloses an automatic return device of an electric rolling door in an obstacle, relating to the field of devices for protecting electric rolling doors. The device disclosed by the utility model aims at solving the problems that a current electric rolling door is easy to damage and incapable of return and the like after meeting the obstacle in the closing process. The electric rolling door adopting the device comprises a motor, a rolling shaft, door pieces, door guide grooves and a door bottom beam, wherein a limit switch is arranged on the motor and comprises an upper limit switch and a lower limit switch; the upper limit control circuit of the limit switch is provided with a microswitch; the microswitch is respectively connected with the lower limit switch and the upper limit switch of the limit switch in series; and the microswitch is fixed at the upper parts of the door guide grooves of the electric rolling door and below the rolling shaft of the electric rolling door. The automatic return device of the electric rolling door in the obstacle, disclosed by the utility model, is simple in structure, convenient to install, safe and reliable.
Description
Technical field
The utility model relates to a kind of protective device of electric rolling door, particularly relates to a kind of electric rolling door and meets the barrier automatic resetting device.
Background technology
At present, the electric rolling door that people use is provided with upper limit position switch and lower position switch usually, but tending to occur especially at closing time inside door when practical operation in the electric rolling door descending stroke occurs meeting the situations such as obstruction, Men Tiyu gate slot are stuck under external-open, the door, simultaneously this situation is not in time found again, the fixed point that is rotated further with regard to causing door-plate damage or door-plate and spool of the spool of electric rolling door comes off subsequently, until the motor of the spacing rear electric rolling door that puts in place of closing the door just can shut down.This has caused the door-plate of electric rolling door damaged, and that the electric rolling door after damaging repairs is particularly troublesome, and maintenance cost is also very high, therefore causes certain economic loss to the user, also affects user's normal use simultaneously.The electric rolling door that has is equipped with power-off protection apparatus and deals with and tend to occur inside door in the electric rolling door descending stroke and meet the situation appearance such as obstruction, Men Tiyu gate slot are stuck to external-open, door are lower; this has protected the door-plate of electric rolling door not damaged in certain degree; but need to manually come the on off state of cleaning accident and adjustment electric rolling door, waste time and energy.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of simple in structure, easy for installation and safe and reliable electric rolling door to meet the barrier automatic resetting device.
For achieving the above object, the utility model provides a kind of electric rolling door to meet the barrier automatic resetting device, described electric rolling door comprises motor, spool, door sheet, door guide groove 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 lower limit control circuit of described limit switch, described microswitch is connected with the lower position switch of described limit switch and microswitch is connected with the upper limit position switch of described limit switch; Described microswitch is fixed in the door guide groove top and under the spool of described electric rolling door of described electric rolling door.
Described microswitch 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.
The lower position switch circuit of described motor is that the upper limit position switch circuit of off-state and motor is closure state during the button pressurized of described microswitch.
The utility model beneficial effect is: use electric rolling door chance barrier automatic resetting device of the present utility model simple in structure, easy for installation; The door body of fundamentally having stopped electric rolling door causes a body damaged owing to meeting obstruction or misoperation in descending stroke; But a door body that has also guaranteed simultaneously electric rolling door in descending stroke, meets barrier or other former thereby when causing normally moving then self-return be opening to a body, bring convenience for the recovery use work of electric rolling door, laborsaving and can effectively increase the service life.
Below in conjunction with accompanying drawing electric rolling door of the present utility model being met the barrier automatic resetting device is described further.
Description of drawings
Fig. 1 is the positional structure schematic diagram of the utility model in electric rolling door.
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.
The specific embodiment
As shown in Figure 1, the electric rolling door that the electric rolling door of present embodiment is met the barrier automatic resetting device comprises motor 1, spool 2, door sheet 3, door guide groove 4 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 lower limit control circuit of limit switch 6, microswitch 9 is connected with the lower position switch 8 of limit switch 6 and microswitch 9 is connected with the upper limit position switch 7 of limit switch 6, and microswitch 9 is fixed in door guide groove 4 tops and under the spool 2 of electric rolling door of electric rolling door.When electric rolling every body falls to running into obstacle, if microswitch 9 and again not in time discovery are not installed, because remaining in operation, spool 2 comes off with regard to the fixed 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.
Microswitch 9 be fixed in a guide groove 4 tops and in the position under the spool 2 of electric rolling door be the spool 2 of the electric rolling door outer door sheet 3 after real by volume on the spool 2 after real with Men Tijuan under 3 centimeters.Lower position switch 8 circuit of motor 1 are that upper limit position switch 7 circuit of off-state and motor 1 are closure state during the button pressurized of microswitch 9.Install behind the microswitch 9 then when electric rolling every body whereabouts runs into obstacle by present embodiment, cause the door sheet 3 and spool 2 loosening supports greatly of a body this moment owing to the rotation of spool 2, the door sheet 3 that just occurs under the spool 2 can be pushed down on the microswitch 9 that arranges under the spool 2, so just the circuit of the lower position switch 8 of motor 1 is disconnected and the closing of circuit of the upper limit position switch 7 of motor 1, this moment motor 1 backward rotation so that the door body scroll up, if thereby realized that electric rolling door is running at closing time in obstacle or other situation that can not run well and can arrive complete opening by automatic homing, therefore can not occur causing the fixed point obscission of door-plate damage or door-plate and spool because spool 2 remains in operation, be convenient to personnel's maintenance after the playback of door body and laborsaving saving time simultaneously.
