| description | In the elevator main engine room, turning gear is one of the indispensable safety devices. The elevator turning gear is used to drive the main engine to rotate when the elevator is closed, and then stop the car at the corresponding position for rescue. The elevator turning mainly includes a disc and a drive shaft, wherein the drive shaft is provided with a gear, which is used to cooperate with the gear on the traction wheel of the main engine to drive the elevator traction wheel to rotate. The turning gear needs to be suspended when not in use. Because the disc is perpendicular to the drive shaft, when the drive shaft is normally installed on the disc, the drive shaft is horizontal, which will affect the space in the main engine room. Of course, there is also a separate design between the drive shaft and the disc. When the drive shaft needs to be installed on the disc through tools, the installation process is more troublesome. In order to solve the above technical problems, this paper studies a foldable manual turning of elevator, which saves space and is easy to install. |
