Abstract

The invention discloses a method used for replacing an escalator driving spindle. The method comprises following steps that an original driving spindle and an original spindle sleeve ring are dismounted from a truss, and an original spindle adapter part is retained on the truss; one side of a first tool is assembled on the original spindle adapter part; a second tool is assembled on the first tool; the second tool is fixed to the truss; the first tool and the original spindle adapter part are dismounted from the truss; the other side of the first tool is assembled on a new spindle adapter part; the first tool and the new spindle adapter part are jointly assembled in the second tool; the new spindle adapter part is fixed to the truss; the first tool and the second tool are dismounted from the truss; the new driving spindle and the new spindle sleeve ring are assembled on the new spindle adapter part; and according to the method, the first tool and the second tool can precisely transmitoriginal spindle positioning benchmark to a new spindle, the new driving spindle after replacement can be precisely assembled on the position, relative to the truss, of the original driving spindle.

Description

technical field [0001] The invention relates to a method for replacing the drive shaft of an escalator. Background technique [0002] GB 16899-2011 and EN 115-1:2017 do not require additional brakes for escalators or moving walks with a lifting height of no more than 6m. In order to protect passengers and improve the safety level of escalators or moving walks, it is necessary to renovate the escalators or moving walks that are not equipped with additional brake functions. [0003] In the current common design, the additional brake and the drive shaft are designed coaxially. Adding an additional automatic function while retaining the truss means replacing the drive shaft of the escalator or moving walk. [0004] In order to ensure the ride comfort of the escalator or moving walk, and at the same time prevent the step chain, step sprocket, drive chain and drive sprocket from premature failure due to wear or impact, it is necessary to strictly determine the drive spindle throu...
