摘要： An obstacle detection device and a door operator includes a hollow bearing, a slide pin, an output bushing, an elastic member, and a sensor, wherein the slide pin is inserted into a through slot of the hollow bearing. One end of the slide pin is accommodated in an open groove of the output bushing, and the elastic member is accommodated in the hollow bearing and is adapted to apply a biasing force to the slide pin. The sensor is disposed on one side of the open groove of the output bushing. During a normal operation, the hollow bearing drives the output bushing to rotate synchronously through the slide pin. When an obstacle is encountered and the output bushing cannot rotate synchronously with the hollow bearing, the output bushing causes the slide pin to be guided by the open groove and slide, thereby triggering or detriggering the sensor.

摘要： The present invention relates to a door operator with an abnormal voltage protection function and a method for abnormal voltage protection of a door operator. According to the present invention, before a door operator motor is electrically energized by an external power source, a controller determines whether the external power source meets the rated voltage of the door operator. In the case that the external power source meets the rated voltage, the controller activates the door operator motor; in the case that the external power source does not meet the rated voltage, the door operator motor is deactivated, and the controller issues a warning.

摘要： The invention relates to a device for releasing and resetting a fire and smoke barrier. In a normal use state, a clutch member is held by an electromagnetic attraction unit, so that a push rod ejecting module cannot be actuated, and a door operator is controlled by a clutch module thereof. Upon power failure, for example upon an accident, the clutch member is released by the electromagnetic attraction unit, and a barrier release member is activated by the push rod ejecting module so as to shut the fire and smoke barrier. Upon power restoration, the clutch member is attracted and held by the electromagnetic attraction unit, and the push rod ejecting module is reset by a push rod resetting module. At the same time, the barrier release member is also reset.

摘要： The present invention relates to a curtain control system and a curtain control method. When a controller receives a curtain-releasing signal, a braking module releases a curtain so as to lower it, a current position detecting module detects an absolute position of the curtain, and the controller calculates a current velocity and a current acceleration of the curtain according to a variation per unit time of the absolute position. When the current velocity is equal to zero or the current acceleration is smaller than zero, the controller controls a motor to lift the curtain or controls the braking module to hold the curtain at a current position. Accordingly, the present invention uses the absolute position to calculate the current velocity and the current acceleration of the curtain so as to determine whether the curtain has encountered an obstacle.

摘要： The present invention relates to a sectional lifting door system. When the system is in normal operation, a door operator drives a cable drum to wind or unwind a cable for lifting or lowering slats. During a process of lowering the slats, if the slats is stopped or slowed unexpectedly (e.g. the slats hit an obstacle below), the door operator is disconnected from a shaft automatically. At this time, even if the door operator is still activated, the shaft does not rotate, the cable drum does not unwind the cable so that a certain tension force can be maintained on the cable and that the cable is prevented from loosening from the drum, thereby preventing the slats from falling off. Also, it can avoid the situation that the weight of the slats is completely applied to the obstacle because the cable drum continuously unwinds the cable.

摘要： A dual-voltage door operator control system comprises a contactor, a high-voltage connector, a low-voltage connector, a rectifier and a brake. When a door operator motor is electrically coupled to the low-voltage connector, the rectifier full-wave rectifies an external power source and then electrically energizes the brake. When the door operator motor is electrically coupled to the high-voltage connector, the rectifier half-wave rectifies the external power source and then electrically energizes the brake. Accordingly, the door operator motor can be connected to the high-voltage connector or the low-voltage connector according to the specification of the external power source provided at the site. Moreover, the invention is also further integrated with the brake of a single specification, and no matter whether the external power source is a high-voltage power source or a low-voltage power source, it can electrically energize the brake through the rectifier.

摘要： The invention relates to a tarp spooling device, mainly comprising a motor, a reduction gear set, a bevel gear set, a tarp reel, and a clutch, wherein the reduction gear set is coupled to the rotor shaft of the motor, the bevel gear set is coupled to the reduction gear set, the tarp reel is coupled to the bevel gear set, and the clutch is coupled between the reduction gear set and the bevel gear set. When the motor is activated, the rotor shaft drives the tarp reel to rotate through the reduction gear set, the bevel gear set, and the clutch; and when the motor is deactivated, the clutch locks the tarp reel, and the tarp reel is unable to be rotated. When the motor is deactivated, the clutch is self-locked, and only when the motor is activated again, the tarp reel can be rotated again.

摘要： A door operator with high-speed operation and fire escape functions comprises a motor, a high-speed centrifugal brake module, a centrifugal reduction module, a central shaft locking module and a first and second clutch module. In the stationary state, the high-speed centrifugal brake module, centrifugal reduction module and central shaft locking module are connected to each other, and the drive shaft of the motor is locked by the central shaft locking module. In the normal operation, the first clutch module disengages the high-speed centrifugal brake module from the centrifugal reduction module, and the drive shaft is rotatable at high speed. In the event of fire escape, the second clutch module disengages centrifugal reduction module from central shaft locking module, and the drive shaft rotates at a lower speed. The device will provide high-speed rotation under normal operation, and automatically close the door panel at a gradually lowered speed in the event of fire escape.
