Briefly describe the safety protection device of the industrial promotion door

There are four main types of safety devices for industrial upgrading doors, namely spring breaks protection device, airbag sensor device, steel wire rope fracture protection device, and infrared shooting safety device (optional).

(1) Spring fracture protection device

The twist spring is the balance system of industrial improvement door, it Control the door to keep parallel when running up and down. If the spring is broken by accident, the balance of the industrial door body will be destroyed, causing the door body to fall and major accidents. This device can stuck the balance shaft when the spring breaks, thereby avoiding the door body fall.

(2) Steel wire rope break protection device

Generally speaking, the wire rope will not break, However, the phenomenon of prolapse may occur, and the wire rope will loosen after the disk. In case of this situation, the steel wire rope fracture protection device will clamp the industrial door side rail to prevent the door body from falling and avoid the occurrence of safety accidents.

(3) The airbag sensor device

The airbag is generally installed in Huaxia, Xufengmen Industry Huaxia The edge of the door of the door of the door network, usually the airbags are saturated. During the closure of the door body, once the pressure is encountered, the pressure will cause the gas in the airbags to be squeezed out. At this time The door bounces up immediately under the action of the device to prevent the obstacles from being clamped and causing accidents.

(4) Infrared shooting safety device (optional)

There will be a set of infrared shooting on the body, and a bouquet of infrared beams will be launched. When the door is running down, if the obstacle is blocked, then the beam cannot be connected to a straight line, and the safety protection system will issue instructions to make the door make the door so that the door will make the door make the door make the door so that the door will make the door make the door so that the door will make the door make the door so that the door will make the door make the door so that the door will make the door make the door so that the door will make the door make the door. The automatic rebound runs upwards and goes straight back to the opening state.
