Description

Technical Field

[0001] The utility model relates to the technical field of sectional lifting doors, in particular to a transmission device of sectional lifting doors. Background Art

[0002] The sectional lifting door is a large door composed of multiple door panels, which is suitable for large openings in industrial plants. Its structure is similar to that of a counterweight-type vertical lifting industrial door. It opens vertically upward along the wall and ceiling, and does not occupy space inside or outside the door. After the door is opened, the door panels are either laid flat under the ceiling or docked vertically on the wall above the door opening, which does not occupy or waste the internal space of the building. Therefore, the installation of the door frame will not affect the net passing width of the opening, but also greatly reduce the risk of being damaged by collision.

[0003] When installing a sectional lifting door, first install the track required for the sectional lifting door, and then install the transmission mechanism. The transmission mechanism is composed of a wire rope and a motor, just like a traction machine uses a wire rope to move the sectional lifting door in the track, and the transmission mechanism is usually installed at a high place, which is the highest lifting point of the bottom of the sectional lifting door.

[0004] When installing the transmission mechanism of the sectional lifting door, it is necessary to perform high-altitude operations, which is difficult to install. In addition, since the transmission mechanism is located at a high place, it is not conducive to subsequent maintenance and replacement, which affects efficiency and poses safety risks. For this reason, we propose a transmission device for the sectional lifting door to solve the above problems. Utility Model Content
