Definitions

  • the present invention relates to a high-speed escalator for a slope, in which the moving speed of a step at an intermediate slope is faster than the moving speed of a step at an upper entrance and a lower entrance.
  • the speed ratio (speed ratio) between the speed of movement of the steps at the upper and lower entrances and the lower entrance and exit is the speed of the steps at the middle slope.

It is considered that when the gear ratio increases, the distance between the drive port and the shaft 10 in the intermediate inclined portion C increases, and the step between the steps 2 also increases. As can be seen from the figure, when the gear ratio is 1.5, the step between the steps 2 is about 30 Omm (about 200 mm in standard ESCARE overnight).
  • This step is a dimension that allows the passenger to easily walk on the step 2. Therefore, in the event of an emergency stop of the escalator, for example, passengers can walk on step 2 smoothly. You can move around.

Abstract

Dans un escalier roulant comportant une partie inclinée très rapide, une pluralité de marches reliées par des courroies sans fin sont déplacées le long d'un chemin de circulation. La vitesse de déplacement des marches est plus rapide au niveau de la partie inclinée intermédiaire qu'au niveau de la partie d'entrée/sortie supérieure et de la partie d'entrée/sortie inférieure. Le rapport de la vitesse de déplacement des marches de la partie inclinée intermédiaire et des parties d'entrée/sortie est inférieur ou égal à deux.
