Description
Technical Field
The invention relates to the technical field of rolling door control, in particular to an electric rolling door.
Background
The rolling door body is made of high-quality stainless steel and the like, is connected by adopting a parallelogram principle, and is flexible to stretch. The driver is driven by a special motor, the worm and the worm wheel are decelerated, and a manual clutch is arranged, so that the driver can be manually opened and closed when power is cut off. The rolling door is characterized in that the door sheets which are articulated are connected in series, and the rolling door rotates up and down in a fixed slideway by taking a scroll above the door as the center, and has the characteristics of stable opening and closing, perspective door body, small occupied space after opening and the like.
However, when the curtain is put down or pulled up or the curtain is blocked, the motor cannot be stopped in time, so that the rolling door is damaged, and even people or objects under the curtain are damaged. At present, in the prior art, for example, in patent CN217681492U, an electric rolling door stopping when encountering a blockage is disclosed, and the technical scheme is as follows: when the door curtain is blocked by the obstacle or is blocked by the door curtain, the driving device continuously drives the rotating shaft to enable the door curtain to protrude towards the side surface of the door curtain due to the fact that the door curtain cannot move in the moving direction, the door curtain is enabled to be abutted to the trigger, the trigger sends a signal, the operation of the driving device is stopped, the rotating shaft stops rotating, the door curtain is not moved any more, the door curtain is prevented from being damaged, the door curtain can be continuously operated after the obstacle and the fault are removed subsequently, the driving device is not required to be manually stopped, the rotating of the rotating shaft can be stopped at the first time when the door curtain is blocked by the trigger, the occurrence of larger loss is prevented, and the effect of protecting the door curtain is achieved. However, when the lower half part of the rolling door is clamped, the protruding part of the door curtain is positioned at the lower part and cannot be abutted against the trigger, the rotating shaft continues to rotate to cause damage to the rolling door, and the door curtain wound around the rotating shaft part is clamped or the rotating shaft is damaged, so that the descending speed of the door curtain is reduced or cannot be reduced, and at the moment, the door curtain has a certain possibility that the door curtain cannot be abutted against the trigger. In addition, when the door curtain is put down, the door curtain wound on the rotating shaft gradually reduces, and the hung door curtain approaches in a forward direction slowly. To prevent false touches, the distance between the triggers should be increased, and the larger the interval between the triggers, the larger the delay for fault detection, and the lower the accuracy.
Therefore, it is a urgent need for a safe and reliable electric rolling door.
