Title:
COWL FOR HIGH-SPEED ELEVATOR CAGE
Document Type and Number:
WIPO Patent Application WO/2012/024929
Kind Code:
A1
Abstract:
A cowl for a high-speed elevator cage, which belongs to the technical field of electric lifting devices, comprises a rectangular upper cover plate (1) from the four edges of which a front cover plate (2), a back cover plate (3), a left cover plate (4) and a right cover plate (5) are extended downwards respectively. The upper edges of the back cover plate (3), the left cover plate (4) and the right cover plate (5) are transiently connected to the upper cover plate (1) through arc segments (6) respectively, while the lower edges have outward vertical folding edges (8) respectively, and the interior side faces are fixedly connected with the arc segments (6) and the upper cover plate (1) through a set of space-arranged reinforcement plates (7) in the form of reinforced rib construction, respectively. During installation, said cowl is fixed on the top of the elevator cage. The arc segments (6) can guide air circulation, and have the effects of reducing the wind resistance and protecting the cage during the high-speed movement of the elevator cage. The reinforcement plates (7) form the reinforced ribs for the back cover plate (3), the left cover plate (4), the right cover plate (5) and the arc segments (6), which can effectively prevent the cowl from being distorted during the high-speed movement of the elevator cage in the wellhole, and greatly reduce the elevator cage's interior vibration and noise.
