Definitions

  • the invention relates to an escalator or moving walkway having at least one access module.
  • a moving walkway having two entrance areas. About this, the arranged between the entrance areas, circulating conveyor belt enter, or be left. Since the moving walkway is arranged on the level floor and not in a pit, the user must reach the higher level of the conveyor belt via a walkway which is subsequently arranged on the moving walkway. As a conveyor belt, an elastic band is provided.
  • the drive components are arranged below a walk-in cover.
  • the drive components include a transmission gear and an electric motor.
  • control components such as switches, relays, motor contactors, frequency converters, transformers and boards with processors and data storage units can be arranged in the entrance area below the walk-in cover.
  • JP 2011 157144 A discloses an alternative solution to prevent heat accumulation below a walk-in cover.
  • the aforementioned arrangement of drive components and control components in the entrance area below the walk-in cover has the advantage that all electrical components are arranged close to each other. This minimizes the wiring effort. Furthermore, the troubleshooting of faults affecting the electrical components is much easier, since all relevant components such as drive motor, control, frequency converter, transformer, relays, motor contactors and the like are immediately accessible with the opening of the walk-in cover.
  • a disadvantage of this arrangement is the high density of loss heat-generating components such as the drive motor, the controller, the frequency converter, the transformer, the relay and the motor contactors. As a result, the negotiable cover can overheat and unsettle the users of the escalator or moving walk. Furthermore, the high density can lead to heat build-up which can significantly shorten the service life of the electrical and mechanical components of the escalator or moving walk.
  • the circulating conveyor belt In the entrance areas, the circulating conveyor belt is deflected. Especially with conveyor belts with pallets, the deflection of the same can lead to operating noise. Also, the drive motor, the transformer and the contactors can cause significant operating noise, so that the space receiving these components must be soundproofed below the walk-in cover. Usually sound-insulating materials are also heat-insulating, so that the risk of heat build-up is even greater.
  • the object of the present invention is therefore to prevent heat accumulation below the walk-through cover, even if loss-heat-generating components are arranged in a tightly packed manner in this area.
  • the escalator or moving walkway includes loss heat generating components disposed in at least one of the entrance areas in a component space below a walk-in cover. Furthermore, the escalator or the moving walkway comprises at least one accessible access module, which is subsequently arranged in the component space.
  • the walk-in access module includes a walk-in area and a cavity. Between the component space and the cavity at least one breakthrough is present, is carried out by the heat energy of the loss heat generating components from the component space in the cavity.
  • the component space can be kept very small. This allows, for example, that moving walks can be made very flat and compact so that they do not need a pit.
  • the flat design of the moving walk also allows a short-building access module, without, for example, the ramp is too steep and hindered impaired users.
  • the heat energy of the loss heat-generating components does not affect the components in the component space, but is transferred into the cavity of the access module.
  • a cooling system defined by the environment is provided, which allows efficient removal of heat energy from the component space, without burdening the environment with, for example, the noise of a cooling fan blowing the warm air from the component space into the environment and dust and dirt swirls around. Furthermore, essentially the same air is always circulated, so that no dirt enters the component space due to the intake of cooling air.
  • the delimiting components and structures do not necessarily have to be all components of the accessible access module. If, for example, a pit is present, the access module can essentially be a walk-in area with a load-bearing structure that sufficiently supports the walk-on area against the ground.
  • the cavity delimiting structures may be three walls and the bottom surface of the pit and an end wall of the structure of the moving walk or the escalator, which separates the component space from the cavity.
  • the walk-in access module all around walls that surround the entire cavity and delimit the environment and the ground.
  • the accessible area of the access module may comprise heat-conducting material, wherein the accessible area is preferably the ceiling end of the cavity.
  • the walk-in area is preferably made of aluminum or stainless steel.
  • the dissipation of heat energy over the accessible area is particularly advantageous because their areal extent to the environment is very large and their visible or enterable surface thereby only a slightly higher temperature than the environment of the access module. This type of thermal energy dissipation to the environment also contributes significantly to safety, since the walk-in area dries quickly due to the slightly elevated temperature, for example, after cleaning or not iced in an outdoor installation.
  • the thermal energy of the loss-heat-generating components can be carried out in various ways from the component space into the cavity.
  • At least a part of the loss-heat-generating components may have cooling elements. These cooling elements can be arranged projecting through the at least one breakthrough and projecting into the cavity.
  • the cross section of the at least one opening can be adapted to the cross section of the cooling elements, so that the at least one opening is closed by the projecting cooling elements.
  • the air present in the cavity serving as a transport medium of the heat energy between the cooling elements and the accessible area, can be conveyed or circulated by means of at least one blower arranged in the access module.
  • a second first embodiment of the invention may be present between the component space and the cavity an air exchange, which is accomplished by the fact that heated by the loss heat generating components air from the component space by at least one breakthrough in the cavity, and cooler air from the cavity by at least one further breakthrough flows into the component space.
  • the cavity can be created by the heat energy input of the loss heat generating components without further means an air flow through which the heated air to reach the accessible area and can cool at this (convection).
  • This air flow can be supported by other means such as a fan or a fan.
  • the air flowing through the aperture is preferably conveyed or moved by means of at least one blower or fan arranged in the access module.
  • the air flowing through the breakthrough can of course also be conveyed or moved by means of at least one blower arranged in the entrance area below the walk-in cover.
  • the loss-heat-generating components usually also include a frequency converter or inverter. Some of these drives or inverters include their own built-in blower. If the frequency converter or inverter is arranged to breakthrough in a suitable manner, the air flowing through the aperture can be conveyed or moved by means of the at least one fan arranged in the frequency converter or inverter.
  • the heated air can be passed in a suitable manner to the accessible area of the access module.
  • Such an installation may for example be at least one flow baffle.
  • the at least one flow baffle can be arranged with its planar extent at least in sections at a distance parallel to the accessible area.
  • the heated or heated air from the loss heat-generating components then flows between an underside of the accessible area and the flow baffle and transfers its heat energy to the accessible area.
  • the at least one flow baffle with its areal extent can also be arranged vertically to the accessible area.
  • These vertically arranged Strömungsleitbleche can structurally reinforce the walk-in area or even supported against the ground of the escalator or the moving walk.
  • the at least one walk-in access module can be designed as a ramp or stairs, wherein the embodiment is preferable as a ramp.
  • At least one accessible access module must be added to the existing escalator or the existing moving walkway, which connects to a component space of the existing escalator or the existing moving walk.
  • this walk-in access module includes a walk-in area and a cavity.
  • at least one breakthrough must be produced between the component space and the cavity, through which heat energy of the loss heat-generating components can be carried from the component space into the cavity.
