Definitions

  • the present invention relates to a work platform system, and, more particularly, to an elevatable mast climbing work platform system for use in blast furnace repair or construction.
  • Elevated working platforms are well known in the art and are commonly used during construction to support workers and equipment at desired elevations. Platforms of this nature include moveable elevating platform assemblies as well as stationary scaffolding.
  • Elevating platform assemblies are typically supported by a single column or multiple columns that are in turn supported by concrete pads or structural steel plates. With the use of a hydraulic rack and pinion power system or lifting hook mechanism, the elevating platform assembly uses horizontal braces of the structural columns to "climb" vertically, thus raising workers and materials to a desired elevation.
  • platform assemblies do not function well. This is because such a platform assembly may, if positioned at a certain elevation level, be close or adjacent to a surface or structure under repair, but, if repositioned to another elevation level having a different width, may no longer be close to or adjacent to the surface or structure, making it problematic for workers to effect repairs thereto. In some instances, there may be parts of the blast furnace wall that cannot be accessed because the platform is larger than the width of the blast furnace.
  • such systems are particularly ill-suited to blast furnace maintenance operations because they typically utilize a rectangular working platform.
  • a crescent-shaped gap extends between the blast furnace wall and the platform intermediate these end points.
  • such gaps could be quite large, thus inhibiting the ability to service the blast furnace wall and potentially restricting the length of the platform.
  • blast furnaces have a substantially inverted truncated conical configuration that extends from a minimum inside diameter of approximately 27 feet to a maximum inside diameter of approximately 40 feet.
  • a work platform that is suspended from the narrower top of the furnace is not easily brought into close proximity to the wider bottom part of the furnace, or precisely positioned thereabout.
  • the present invention discloses an elevatable mast climbing work platform system for use in blast furnace repair, which enables a transport elevator carrying materials and/or personnel to travel to or from a working platform at a selected elevation in the blast furnace interior to a ground surface, without substantially moving the working platform from the selected elevation.
  • the present invention further has a circular elevatable working platform having an adjustable diameter that is able to quickly conform to and substantially accommodate variations in the width of the blast furnace interior along its vertical extent with substantially no gap between the platform and the wall.
  • a mast climbing work platform system for providing access to a point at a height along an interior wall surface of a structure, the wall surface extending substantially vertically from a bottom and having varying perimeters along its vertical extent, the system comprising a base portion positioned inside the wall surface; a tower mast secured to and extending substantially vertically above the base portion to at least substantially a height of the point; a substantially horizontal platform secured to the tower mast and vertically movable therealong, whereby the platform is adapted to extend to at least substantially the height of the point and having a perimeter expandable to a size whereby access may be provided therefrom to the point on the wall surface; and an elevator secured to the tower mast and vertically moveable therealong and adapted to extend at least to substantially a height of the platform, whereby personnel and materials may be delivered to and from a loading area of the structure.
  • a mast climbing work platform kit for providing access to a point at a height along an interior wall surface of a structure comprising a base portion; a tower mast adapted to be secured to and to extend substantially vertically above the base portion to at least substantially a height of the point; a platform adapted to be secured to the tower mast for vertical movement therealong and for extension to at least substantially the height of the point, and having an adjustable perimeter whereby the platform can be adjusted to assume a size whereby access may be provided therefrom to the point on the interior wall surface; and an elevator adapted to be secured to the tower mast for vertical movement therealong and adapted to extend at least to substantially a height of the platform.
  • Figure 1 is a perspective view, partially cut-away, of an exemplary embodiment of the present invention
  • Figure 2 is a perspective view from above of the platform of Figure 1, which illustrates, in a cut-away and expanded view, components of the platform.
  • the panels 251, 252 are covered with wire mesh or chain link, so as to permit visibility through the enclosure 250 from outside or inside the construct elevator 30.
  • that portion of the opening 211 that is not surrounded by the enclosure 250 may be covered by a floor 253, which is shown in cut-away fashion in Figure 2.
  • the platform 40 is driven by the hydraulically activated series of hooks along the support column 22 of the tower mast 20 to a selected desired working elevation within the interior of the blast furnace 2, and the perimeter of the platform 40 is expanded or contracted to provide access therefrom to all of the interior wall surface furnace 4 at the selected working elevation.
  • the elevator 30 may be driven by the continuous screw or worm gear assembly along the structural column 25 of the tower mast 20. As it approaches platform level, it is matingly received within the opening 211 in the platform 40, whereby personnel and materials can be passed through the enclosure 250 and onto the platform 40 at the selected working elevation.
  • Personnel and/or materials may be loaded and unloaded from either through the furnace top opening 3 or through the blast furnace 2 at the tuyere or ground level or at some point intermediate thereto.
  • the present invention provides an innovative elevatable mast climbing work platform system 1 for use in blast furnace repair which enables a transport elevator carrying materials and/or personnel to travel to or from a work platform 40 at a selected elevation where the work is taking place to a loading area 40, without substantially moving the work platform from the selected elevation.
  • the present invention provides a substantially circular, elevatable working platform having an adjustable diameter that is able to quickly conform to and substantially accommodate variances in the width of interior walls 4 the blast furnace 2 along its vertical extent.
  • the system 1 may be at least partially assembled outside the blast furnace 2, with final assembly of all components taking place inside the blast furnace 2.

Abstract

L'invention concerne un système de plate-forme de travail pour un positionnement à l'intérieur d'une structure, telle qu'un haut-fourneau. Une partie de base est placée à l'intérieur de la structure et un mât-tour fixé à celle-ci s'étend verticalement à partir de celle-ci. Une plate-forme annulaire et un ascenseur sont fixés à un mât-tour pour un mouvement vertical le long de celui-ci, et la plate-forme a une ouverture définie à travers celle-ci pour permettre le passage de l'ascenseur. La plate-forme peut être étendue et déployée radialement pour fournir un accès à n'importe quel point à l'intérieur de la structure, tout en permettant sensiblement des variations de largeur à l'intérieur de la structure. Contrairement aux systèmes classiques, le repositionnement du système autour de la structure pour accéder aux parois verticales de celle-ci est sensiblement évité et le système est apte à être transportable dans un état démonté.
