Description

Technical Field

[0001] The invention belongs to the technical field of flipping doors of shelters, and in particular relates to an electric double-cylinder synchronous start-stop device for a flap door. Background Art

[0002] A shelter is a box-like workspace composed of various sturdy materials, with a fixed or expandable volume, providing protection and transport capabilities. Because the shelter is constructed of sturdy materials, its doors, as part of its structure, are heavy and bulky. Opening and closing the doors when transporting cargo in a shelter can be difficult, especially when the doors are tilted relative to the shelter.

[0003] The patent with application number CN202022758737.3 discloses a lifting door flipping mechanism, which includes a roller, a pulley, a wire rope, a driving mechanism, a first travel switch and a second travel switch. The roller is installed on the door frame, the pulley is installed on the lifting door, and the wire rope is wrapped around the pulley and wound on the roller; the driving mechanism is a worm gear reducer, and the output shaft of the worm gear reducer is fixedly connected to the first roller and the second roller; the driving mechanism is used to drive the roller to rotate to wind or unwind the wire rope, thereby linking the lifting door to flip; when the lifting door flips to the open state, the first travel switch is triggered; when the lifting door flips to the closed state, the second travel switch is triggered.

[0004] This tilting mechanism utilizes a reduction motor and a travel switch in communication with each other, and is coordinated with a drum, pulley, and wire rope. The wire rope is installed between the pulley and the drum. The pulley is mounted on the lift door via a pulley seat, and the drum is mounted on the top of the door frame via a roller seat to control the opening and closing of the lift door. This tilting mechanism is relatively complex. When the lift door is large and heavy, the tilting mechanism cannot withstand the frequent opening and closing of the lift door, which can easily cause wear or failure of the drum, pulley, and wire rope. During operation, the worm gear reducer rotates the drum, thereby controlling the contraction or relaxation of the wire rope. Driven by the wire rope, the lift door slowly tilts downward or upward, resulting in low opening and closing efficiency. When two drive motors are installed on either side of the door frame, the wire ropes on each side can drive the lift door to tilt. However, since the wire ropes on each side are driven by different drive motors, it is easy for the two sides of the lift door to tilt out of sync. Summary of the Invention

[0037] The adapter interfaces 11 of the reducer adapter 7, the first shaft adapter 8, and the second shaft adapter 9 are connected to an input shaft 13 or an output shaft 12. The number of input shafts 13 and output shafts 12 can be specifically set according to the connection requirements of the adapters.

[0038] Specifically, with reference Figure 1 、 Figure 2 as well as Figure 3 The device includes a motor 1, to which a reducer 2 is connected, and the reducer 2 is connected to a reducer adapter 7.
