  • the chute installed while moving to the stock yard via multiple belt conveyors and classifiers may repeatedly receive localized impacts of blocks containing ores and rocks.
  • the chutes used in the above are damaged, deformed and worn quickly and are frequently repaired.
  • the repair method is usually the case where the contact plate or deformed part by electric welding is cut with a gas cutting machine, and a new plate is fitted and welded according to the cut shape, but when wear progresses, the plate thickness decreases. Due to lack of strength, the repaired part may be damaged again in a short time, and when the deformation progresses, a lump etc. is caught in the deformed part, so that it stays or accumulates in the chute and eventually the chute is blocked. It may cause new troubles.
  • the problem of operation is that repairs to recover the damage, deformation, wear, etc. that cause it often involve unscheduled operation stoppages.
  • the operation stop is planned in advance, and the inspection and repair are carried out during that period, so the influence on the operation plan is small.

  • chute malfunction Suppressing sudden repairs is important for achieving the operation plan.
  • the techniques for improving the wear resistance and impact resistance of the chute that are actually used are generally (1) a method of attaching a plate (sacrificial plate) to the worn portion of the chute, and (2) an abrasion resistant material. And (3) a method of attaching a cushioning material to improve impact resistance.
  • these methods have the following problems.
  • the method of pasting the sacrificial plate on the chute is a method of attaching a sacrificial plate with the same material and thickness as the chute by welding. It is. Although it is a widely used method, the thickness of the plate does not affect the strength of the chute even if the plate thickness is increased to extend the life because the material is not wear resistant (equivalent to the thickness of the chute material). In general, even if the thickness is increased somewhat, it will be consumed in several months, and re-repair is required. Thus, since the effect is limited, there is a problem that it is difficult to suppress sudden repair in the same means.
  • cushioning materials are mainly represented by rubber-based materials, as with wear-resistant materials, materials with various properties are on the market and are selected in a wide variety. It is relatively easy to obtain and inexpensive ones can be selected. However, if the fall energy is absorbed by buffering the impact, the block stays on the chute and may cause a blockage trouble. In addition, those with poor wear resistance will be damaged and worn out and will be consumed in about 1 to 2 months, and the chutes may accumulate or accumulate at the locations that have been torn due to wear, and the trouble of clogging the chute is likely to occur. Since the effect of wear resistance is limited in the same manner as that of the sacrificial plate, there is a problem that it is difficult to obtain further effects in the same means.

Abstract

L'invention concerne une glissière qui permet d'obtenir une plus longue durée de vie en améliorant la résistance à l'usure. Une glissière (1), qui est installée au niveau d'une inclinaison vers le bas sur un transporteur (50), qui transporte des objets (g), est pourvue d'un moyen de retenue (10) qui retient une partie des objets (g) qui tombent du transporteur (50) sur la surface de glissement de la glissière (1). Le moyen de retenue (10) présente une section de stockage (13) ayant une forme de treillis par une combinaison d'une pluralité de traverses verticales (12), qui s'étendent dans la direction longitudinale, et d'une pluralité de traverses horizontales (13), qui s'étendent dans le sens de la largeur de la glissière (1). Étant donné que le moyen de retenue (10) est en forme de treillis, une quantité appropriée d'objets (g) qui sont tombés du transporteur (50) peut être stockée et retenue de manière à ne pas glisser, de telle sorte que peu d'objets retenus sont remplacés par d'autres objets. Ainsi, les objets retenus agissent eux-mêmes comme matériau de rembourrage sacrificiel sur une longue période et peuvent empêcher l'apparition de points d'usure/d'endommagement sur la glissière (1), réduisant ainsi la fréquence de réparation.
