Description

Technical Field

[0001] This utility model relates to the field of flip-up door technology, and more particularly to electric flip-up doors. Background Technology

[0002] In existing construction projects, the distance between the hoist cages is relatively long, requiring large flap doors for transition. Manual large flap doors serve as a platform bridging the building and the hoist cage. These doors are sturdy and heavy. However, manual large flap doors have many limitations in practical use, particularly in terms of convenience, safety, and adaptability.

[0003] Some shortcomings of the flip-door technology: Manual flip-doors rely entirely on human power to open and close. Large manual flip-doors are welded from metals such as square tubes and patterned steel plates, making them quite heavy. Opening them requires force, which is extremely unfriendly to operators. On existing construction sites with tight schedules, construction hoists are used frequently, and opening and closing the door every time someone enters or exits is labor-intensive and inhumane for the driver. The light-reducing springs of manual flip-doors are prone to fatigue and loss of elasticity due to repeated manual pulling, so spring parts must be replaced frequently, resulting in high after-sales maintenance costs.

[0004] In summary, the only advantage of manual flip doors is their lower purchase cost, but they have shortcomings in terms of high labor intensity, lack of humanization, and high maintenance costs. Therefore, an electric flip door is proposed. Utility Model Content

A transmission drive assembly is provided on the cage, and a chain is connected to the transmission drive assembly. The chain is connected to the flip-up door body, and the opening, closing, and rotation of the flip-up door body are achieved through the transmission of the chain.

[0007] Preferably, a folding fence is rotatably installed on one side of the cage, and the folding fence is rotatably connected to the flip-door body.

[0008] Preferably, the transmission drive assembly includes a motor fixedly mounted on the cage, the motor being provided with a protective cover, and the output end of the motor being connected to a transmission mechanism.

[0009] Preferably, the transmission mechanism includes a main sprocket mounted on the output end of the motor, a first auxiliary sprocket mounted on the cage, and a second auxiliary sprocket mounted on the flap door body.

[0010] Preferably, one end of the chain is wound around the main sprocket, and the other end is fixedly installed on one side of the cage. The chain is connected to the first secondary sprocket and the second secondary sprocket in sequence.

[0011] Preferably, the cage is equipped with a door closing limit and a door opening limit, both of which are adapted to the flap door body.

[0012] Preferably, the flap door body is made of metal.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The electric flip-door has its motor and transmission mechanism installed on the top of the cage, reducing the space occupied by the cage and making the installation position more reasonable.
