Definitions

  • the disclosed invention patent is a system for removing nuts and tails for mill liners, the objective of the disclosed design is to improve the speed and safety in the work of removing nuts, tails and bolts from internal mill liners used in different industrial or mining applications.
  • the change of the linings of the mills is the critical task that defines the total times for maintenance and therefore tools, equipment, accessories, procedures, etc. are permanently sought. that help to do it in the shortest possible time but maintaining appropriate security.
  • That neck has been used in mining plants but there is some resistance in some of them because, if used with a motorized wrench, until both parts are completely removed, they fall off. That forces you to do one of two things: the nut and the neck are finished by hand so that they do not fall or are completely removed but the area under the space in which you work is removed by removing nuts and bolts.
  • Figure 1 View of the original neck already patented.
  • Figure 2 View of the modified golilla (1) that is disclosed.
  • Figure 3 View of the die (2) that takes the nut and the neck.
  • Figure 4 View of the neck assembly (1), die (2) and nut (3). Detailed description of the invention
  • the system for removal of nuts and tails for mill liners comprises a double hook taper (1) (1.1) and a double socket (2) with hook (2. 1), adapted to the taper (1).
  • the disclosed system enables short times to be achieved and at the same time provides the necessary security when used with a motorized wrench.
  • the neck (1) has two hooks (1. 1) but they are also displaced from the surface that is in contact with the nut (3); This improvement makes part of the neck (1) enter the cylindrical hole (2.2) of the die (2), which prevents the displacement between the two pieces unless they are consciously disengaged, completing the rotation of both pieces with each other.

Abstract

Les solutions actuelles consistent à : tout d'abord, sortir l'écrou puis la rondelle, un processus lent, b) retirer l'écrou conjointement à la rondelle avec la rondelle à crochet simple, un processus peu sûr, enfin terminer à la main, l'instabilité produisant des accidents aux opérateurs. Le système selon l'invention utilise la même idée basique de la rondelle avec crochet mais on ajoute un second crochet et un emboîtement cylindrique type baïonnette qui permet leur sortie conjointement jusqu'à la fin sans utiliser les mains et sans tomber. Les avantages sont : ledit système réduit les temps totaux, écrous et rondelles sortent conjointement jusqu'à la fin, il n'est pas nécessaire de terminer à la main, ce qui réduit la possibilité d'accidents, la taille dudit système est réduite du fait qu'il ne forme qu'un seul bloc.
