Definitions

  • the invention relates to a wear protection lining for the protection of surfaces which are exposed to wear from abrasive bulk materials, with wear protection plates arranged in a bandage on the surface to be protected, each consisting of a wear layer and a carrier element, the wear layer of the wear protection plates providing an uninterrupted and undisturbed surface having.

  • Wear-resistant linings of this type are generally used in the conveyance of relatively hard bulk goods, for example in the conveyance of minerals or the like, where both abrasion wear and impact wear occur.
  • Typical applications are bunker coils, shaft coils, bunker inlets, spiral chutes, belt chutes in open-cast mines or processing plants or shovels from digging equipment. It is known to produce such wear protection linings from a bandage of wear plates, which are individually welded or glued to the surface to be protected. Wear protection plates made from melted basalt are also installed in a mortar bed, for example.
  • DE-OS 25 08 593 relates to the fastening of aluminum oxide porcelain plates as wear protection in the area of bunker or funnel inlets. Based on the fact that such aluminum oxide porcelain plates were previously laid in the mortar bed, which is considered inadequate with regard to the secure fastening of the plates, it is proposed in DE-OS 25 08 593 to design the wear protection plates in several parts, ie the aluminum oxide plate with a support plate to glue.
  • DE-OS 27 42 196 This is known for example from DE-OS 27 42 196.
  • the fastening screws penetrating the wear protection plates have the disadvantage that the thickness of their wear layer cannot be fully utilized because of the screw heads countersunk in them. If a certain removal is exceeded, further wear leads to the screw head being removed. As a result, the attachment of the plate in question is lost early.
  • DE-OS 27 42 196 proposes a special geometry of the fastening holes and a corresponding design of the screw heads, the fastening selected in DE-OS 27 42 196 the wear protection plates also presupposes that the surface to be protected is accessible from the rear.

Abstract

L'invention concerne un habillage de protection anti-usure servant à protéger des surfaces qui sont exposées à une détérioration par des matières en vrac abrasives. Cet habillage de protection anti-usure est constitué essentiellement de plaques de protection anti-usure (1'a) disposées en un assemblage sur la surface à protéger. Chaque plaque de protection anti-usure est constituée d'un revêtement d'usure et d'un élément de support, ledit revêtement d'usure présentant une surface ininterrompue et uniforme. L'habillage de protection anti-usure présenté se caractérise en ce que les éléments de support d'au moins certaines plaques de protection anti-usure (1a, 1b) comportent, sur leur face opposée au revêtement d'usure, des moyens (5, 6) à fixer, de façon amovible, par encliquetage et liaison de forme, dans des logements (8) de forme correspondante, ménagés sur la surface à protéger.
