Embodiment Construction
[0011] see Figure 1 to Figure 6 , when the door curtain 15 of the rolling door rises and stops under the drive of its driving device, the electromagnet A3 and electromagnet B4 of the clamping device 1 are energized at the same time, the electromagnet A3 and the electromagnet B4 attract each other, and the spring 5 elastically compresses, and Drive a pair of connecting rods 6 to rotate inwards, and a pair of connecting rods 6 drives a pair of clamps 7 to rotate inwards, and a pair of clamps 7 clamps the side wall 18 of the door curtain sliding sleeve 17, no matter the position of the door curtain 15 When the sprocket of the driving device is decoupled, broken or in other abnormal conditions, a pair of clamps 7 of the clamping device 1 can prevent the door curtain 15 from falling. The electromagnet A3 and the electromagnet B4 are powered off, the electromagnet A3 and the electromagnet B4 lose their attractive force, the spring 5 is elastically elongated, and drives a pair of cl...

The invention discloses a clamp type anti-falling device for a roller shutter door, and the device is mainly used for preventing the roller shutter door from falling to hurt people and is simple in structure and safe and reliable in protection. The device is composed of a forceps holder device and a trigger device. The working principle is as follows: when a door curtain of the roller shutter doorascends and stops, an electromagnet A and an electromagnet B of the forceps holder device are electrified, a pair of forceps clips of the forceps holder device clamps the side wall of a door curtainsliding sleeve for preventing the door curtain from falling down, and when the door curtain descends, the door curtain descends, the pair of forceps clips of the forceps holder device is loosened, thedoor curtain slides downwards at a normal speed. If the door curtain suddenly falls down, a rotor of the trigger device suddenly accelerates, generated induction current is suddenly increased, the force between a movable electromagnet and a fixed electromagnet of the electromagnetic switch is increased, the electromagnetic switch turns on a power supply of the electromagnet A and the electromagnet B of the forceps holder device, the electromagnet A and the electromagnet B attract each other, the pair of forceps clips is driven to clamp the side wall of the door curtain sliding sleeve to prevent the door curtain from falling.
Description
technical field [0001] The invention is mainly used for preventing the rolling shutter door from falling down and injuring people. Background technique [0002] The anti-falling devices for rolling shutter doors that have been applied for or are in use have complicated structures and high maintenance and repair costs. Contents of the invention [0003] The present invention solves the above problems. It has a simple structure and can prevent the rolling door from falling in various states, and the protection is safe and reliable; it consists of a clamping device (1) and a triggering device (8); the rotating shaft of the clamping device (1) ( 2) It is fixed with the bottom hinge (16) of the door curtain (15) of the rolling door; the clamping device (1) consists of a rotating shaft (2), an electromagnet A (3), an electromagnet B (4), a spring (5), Composed of a pair of connecting rods (6) and a pair of clamps (7), the left end of the electromagnet A (3) is fixed to the left...
