[0002] An electric flip door is often used for the gates of industrial plants, warehouses, garages, etc. Most of the electric flip doors currently used are wire rope traction type. A transmission shaft is arranged on the upper inner side of the door leaf, and the transmission shaft is driven by a motor. A roller is arranged on the transmission shaft, and the roller is connected to the door leaf by a wire rope. When the door leaf needs to be opened, the motor drives the transmission shaft to rotate, so that the roller winds the wire rope, thereby pulling the flip door upward and opening it. When the door leaf needs to be closed, the motor drives the transmission to rotate in the opposite direction, so that the roller unwinds the wire rope, and the flip door closes downward under the action of gravity. It has the advantages of compact structure, stable operation, flexible opening, and convenient installation and maintenance. However, when the wire rope traction type flip door is closed, the wire rope between the roller and the door leaf is in an oblique state, which occupies a large indoor space and is easy to affect the indoor operating machinery, thereby causing safety accidents.

[0061] Working principle:

[0062] When the up-flip door body needs to be opened, the lifting motor drives the transmission shaft to rotate, and the winding roller on the transmission shaft winds the wire rope to reel up the wire rope. During the reeling process, the wire rope gives an upward pulling force to the second pulley, and the slide gradually slides upward on the slide rail under the action of this pulling force until the pulley slides to the position of the first pulley, at which time the wire rope continues to be reeled in to gradually open the up-flip door body; when the up-flip door body needs to be closed, the lifting motor drives the transmission shaft to rotate in the opposite direction, and the winding roller on the transmission shaft unwinds the wire rope to loosen the wire rope, and the up-flip door body gradually closes downward under the action of gravity. After the up-flip door body is closed, the winding roller continues to unwind the wire rope, and the pulley slides downward under the action of gravity, thereby driving the steel wire to gradually stick to the up-flip door body, preventing the wire rope from being obliquely pulled on the rear side of the up-flip door body, thereby occupying a large space and affecting indoor operating machinery.
