Description
Technical Field
[0001] The utility model relates to the technical field related to industrial lifting doors, and in particular to an industrial lifting door with an externally mounted transmission system. Background Art
[0002] Industrial lifting doors are composed of a series of door panels and rise along the track. According to different operating modes, they can be divided into standard lifting industrial lifting doors, vertical lifting industrial doors, high-position lifting industrial doors, sliding industrial doors, sectional lifting industrial doors, special lifting industrial doors, etc. Due to their better sealing performance and higher safety performance, industrial lifting doors are often used as factory gates and are a more common industrial door body.
[0003] The current transmission structure of industrial lifting doors mostly uses a torsion spring system and a counterweight system to ensure the balance of the door body. However, this transmission method causes most of the structures in the transmission system to be installed in the internal structure of the lifting door. Once any fault occurs in the transmission system, maintenance personnel are required to climb to a high place and dismantle the lifting door before they can repair and replace components in the transmission system. This has poor flexibility and there is room for improvement. Utility Model Content
