The present invention refers to a support, to a module to be placed on the support, to a transport system for displacement of people/goods modernized with the module of the invention and to a modernization method of transport systems for displacement of people/goods, for example, escalators.
U.S. Pat. No. 6,685,002 discloses a method of modernizing an escalator using modular components. The mechanical and electrical parts of an existing escalator are removed, leaving only the structural truss framework and cross members as well as all external parts, such as external panels, that interface with the building. A single module is placed at the top of the escalator and another module at the bottom. A plurality of incline modules are placed in the central inclined part of the escalator, at each cross member. By utilizing these modules, the assembly of the escalator is simplified. Furthermore, an entirely new escalator system using the latest technology may be installed rather than merely installing new parts in an old system.
GB 2121748 discloses a reconstruction method for improving an obsolete escalator having a frame with supporting members projecting inwardly therefrom, mounting various constituents such as an endless series of moving steps, handrails moving in synchronism with the steps, a drive unit and drive sprockets, balustrades standing upright at both sides of the steps, and rails for guiding the steps comprising the steps of: removing the constituents from the frame of the obsolete escalator; removing the supporting members from the frame; mounting a second frame in the frame, the second frame being provided with supporting and base members already attached thereto for supporting the various constituents of a new escalator; mounting the balustrades, drive unit, rails and so forth, as well as series of steps, of the new man conveyor on the second frame; and covering the gaps between the second frame and the frame by outer deck members secured to the second frame.
The invention refers to a support, to a module to be placed on the support and to a modernized transport system for displacement of people/goods such as those defined by the set of claims. The invention also refers to a modernization method of transport systems for displacement of people/goods, incorporating a module of the invention.
Depending on the positioning of the support and the module for the system modernized according to the invention to keep the working points of the system to be modernized, the method can be fixed or adjustable.
The fixed method comprises:
1) Finding the working points of the system for the transport of people/goods or of the original escalator and transferring them to a physical point.
2) Dismounting all the components of the people/goods transport system or of the original escalator except for the structure.
3) Positioning the module supports on the structure with precision with respect to the working point.
4) Placing the modules on the supports making the tie plates of the supports and the module plugs coincide. If the positioning of the supports has been correct, the working points of the machine coincide with those of the modules, thanks to the manufacturing precision of the modules which guarantees a tolerance between the anchoring plugs and the working point of the module. It is necessary to verify the correct positioning of the modules before continuing.
5) Establishing an alignment system between the entrance module, which can be a lower module, in the direction of the nose line. The auxiliary alignment system can be a thin rope or an emitter—retroreflective target alignment laser system. At this point it can be verified that this auxiliary line forms the desired degrees with the horizontal.
6) Positioning the necessary central modules along the central section or inclined section in the case of difference between the entrance and exit levels, as in an escalator. The central modules comprise an alignment measurement aperture or target configured to align the central module with the auxiliary line.
7) Completing the mounting of the transport system with the rest of the elements once the upper, lower and central modules are in their place. In the head modules, that is, in the upper and lower modules, most parts of the escalator are already preassembled at the factory, since it is where most mechanisms are concentrated. The central area, which can be completed on site until closing the circuit, entails simpler execution tasks.
In the adjustable method some stages are changed:
3′) Positioning the bases or supports near the working point.
4′) Placing the modules on the supports, in this adjustable method, there are adjustment means in all directions between support and the module. The adjustment means enable to make the working points of the modules coincide with those of the original system to be modernized. In order to attain the horizontality of the module a level can be used.
In both procedures it is attempted to respect the original cross members of the structure, that is, the transverse beams that join the sides of the structure. However, if at a certain point the transverse beams interfere with the new system, they are eliminated and replaced by other elements of at least the same mechanical resistance.
