Gates are control mechanisms for large traffic passage between unauthorized and authorized zones in public applications. The subway gate is widely applied and serves as isolation equipment for paid areas and unpaid areas of subway stations. At present, rail transit, intelligent management and other fields increasingly adopt a gate with a column rotary structure as an execution component, and the gate is relatively beautiful in appearance, simpler in structure compared with a shear type gate and a three-rod type gate, smaller in size, more convenient to maintain and popular; the gate passage is closed under normal conditions, and in order to ensure that pedestrians are evacuated safely or other requirements are required to be cleared quickly under emergency conditions such as fire or power failure, the power failure door opening becomes one of the more and more essential functions. The existing rotary gate mechanism is mostly realized by adding a tension spring, a traction belt or other linear non-elastic elements outside.
When the mechanism normally works, the motor drives the rotating shaft to rotate, the rotating shaft drives the fixedly connected traction belt to stretch the tension spring, so that the door leaf is stopped at different positions, the tension force always exists, when the door leaf is positioned at the door opening position, the door closing position or any intermediate position, the mechanism is powered off, and the door leaf can be restored to the door opening position initially set due to the tension force always possessed by the tension spring, and the door opening reset is realized.
Because the rotary type door leaf mechanism has larger movement angle and needs to rotate forward and backward by 90 degrees, the stroke of the tension spring and the length of the traction belt are both longer, but the tension spring in the prior art is unreasonable in structural layout and needs independent space for installation and arrangement, so that the occupied space of the whole mechanism is increased.

Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the present embodiment discloses a revolving door power-off self-resetting device, which includes a door rotating shaft 1, a door leaf 2 and a motor 7 for driving the door rotating shaft 1 to rotate, the door rotating shaft 1 is connected to a side portion of the door leaf 2, the present embodiment further includes a reset plate 3, an elastic belt 4 and a support frame 5, the reset plate 3 is disposed between the motor 7 and the door rotating shaft 1 and rotates synchronously with the door rotating shaft 1, and the elastic belt 4 is connected to the reset plate 3 and has an elastic force for enabling the reset plate 3 to rotate towards the opening direction of the door leaf 2. That is, during the normal rotation of the door 2, no matter what position the door 2 rotates to, the elastic belt 4 is always lifted to the reset plate 3
A pulling force is applied which can always drive the door 2 to rotate in the opening direction against the torque of the rotation shaft 1.
The connection of the other end of the elastic band 4 is: the support frame 5 is provided with a support column 51, and the elastic belt 4 is connected to the support column 51. The elastic band 4 can be connected to the reset plate 3 by rivets or screws, so as to prevent the elastic band 4 from sliding with the reset plate 3, and disable the reset function. The elastic belt 4 is one or two of a rubber belt and a tension spring.
The embodiment further comprises a base support 6, and the motor 7, the reset plate 3 and the door leaf rotating shaft 1 are all installed on the base support 6.
Still be equipped with the gearbox between motor 7 and door pivot 1, motor 7 sets up perpendicularly in door pivot 1, and support frame 5 is on a parallel with the axis of motor 7, and the purpose that sets up like this makes elastic webbing 4 be on a parallel with motor 7, and sets up with motor 7 stack, reduces occupation space.
During operation, the motor 7 drives the door leaf rotating shaft 1 to rotate through the gearbox, so that the door leaf 2 is opened or closed, in the working process of the door leaf 2, the motor 7 and the elastic belt 4 provide torque for the door leaf rotating shaft 1 at the same time, and the motor 7 overcomes the torque provided by the elastic belt 4 to drive the door leaf rotating shaft 1 to work.
Since the opening direction of the door 2 is two, the working range of the door 2 is 180 degrees in actual work. Reset plate 3 is installed at the motor connecting end of door leaf pivot 1, follows door leaf pivot 1 synchronous revolution, and when the outage, motor 7 loses the electricity, loses the moment of torsion, only relies on elastic webbing 4, reset plate 3 to provide the moment of torsion to door leaf pivot 1 this moment, and door leaf 2 can resume to the open position, and the pedestrian of being convenient for is evacuated safely or other demand reasons need be let pass fast.
The embodiment also discloses a gate which comprises the rotating door power-off self-resetting device.
Compared with the prior art, the embodiment adopts the elastic belt 4 and the reset plate 3 to provide the torque in the opening direction for the door leaf rotating shaft 1, the elastic belt 4 is arranged on the side part of the motor 7 and is fixed through the support frame 5, and the support frame 5 is arranged in parallel with the motor 7, so that the installation volume is reduced. The elastic belt 4 is integrally in a belt shape, and is horizontally placed after being installed, so that the occupied space is small. In actual design, the elastic belt 4 and the support frame 5 do not need to independently occupy installation space.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
