Description
Technical Field
The invention relates to an escalator driving spindle mounting device and an escalator driving spindle mounting method.
Background
In the process of installing the drive spindle of the escalator, it is necessary to adjust the axial position of the drive spindle relative to the truss to a preset optimum position, since this has an important influence on the operation, life, noise, etc. of the entire escalator.
For the new escalator, the adjustment of the axial position of the drive spindle is done in the factory. When the drive spindle needs to be replaced or reinstalled at the site of use, a worker must adjust the axial position of the drive spindle at the site of use, and at this time, the axial position of the drive spindle is often difficult to adjust due to conditions and space limitations.
In the prior art, the adjustment of the axial position of the drive spindle is usually achieved by rotating a socket head cap screw. The adjusting mode has the advantages of simple structure and easy adjustment. The disadvantage is that the adjustment needs to be carried out from outside the truss, and therefore, sufficient operating space needs to be reserved for the adjustment tool outside the truss. However, there is usually not enough operating space outside the truss, and therefore, in the prior art, adjustment of the axial position of the drive spindle cannot be achieved.
