Escalator or moving walkway
View Patent ↗An escalator or moving walkway having a frame, to which rails for chain rollers and rails for idling rollers are fixedly mounted, in particular with the aid of side panels, the escalator or moving walkway further comprising a turn-around area for the chains thereof that comprises a tensioning station for the chains. The tensioning station is guided and mounted on a side part that is fixedly mounted to the frame independently of the support structure.
1. An escalator or moving walkway, comprising:
a frame;
rails for chain rollers and for idling rollers, wherein said rails for said idling rollers are fixedly mounted on said frame;
a side part as part of a turn-around area for chains of said escalator or moving walkway, wherein said side part is fixedly mounted on said frame, wherein said side part is formed by a side panel; and
a tensioning station for the chains, wherein said tensioning station is integrated into the side panel within a recess.
2. An escalator or moving walkway according to claim 1 ,
wherein said tensioning station is provided with a tension spring that abuts against said side part that is fixedly mounted on said frame.
3. An escalator or moving walkway according to claim 2 , which further comprises a bearing, wherein said tensioning station is mounted on said side part that is fixedly mounted on said frame via said bearing.
4. An escalator or moving walkway according to claim 3 , wherein said bearing is a slide bearing.
5. An escalator or moving walkway according to claim 3 , wherein said tensioning station is provided with a frame with which said tension spring and a safety switch are connected for monitoring of elongation of a step chain or a pallet chain.
6. An escalator or moving walkway according to claim 5 , wherein said safety switch is a trip cam switch.
7. An escalator or moving walkway according to claim 5 , wherein said safety switch is disposed in such a way that it is also shifted along during a retensioning of the chains via said tensioning station and therefore does not have to be readjusted.
8. An escalator or moving walkway according to claim 1 , wherein said tensioning station is provided with a side part, and wherein said rail for chain rollers is provided with laterally attached pins for positioning of said chain roller rail in corresponding recesses of said side part of said tensioning station.
9. An escalator or moving walkway according to claim 1 , wherein components of said tensioning station are fixedly connected to one another.
10. An escalator or moving walkway according to claim 9 , wherein the components of said tensioning station are joined by laser welding.
11. An escalator or moving walkway according to claim 1 , wherein in said turn-around area, between idling roller rails fixedly mounted on said frame and said side part that is fixedly mounted on said frame, said chain roller rails are resiliently guided to maintain chain tension.
