Abstract

The anchorage device comprises a special threaded shaft (1) equipped with an anchorage ring (2), a drilled part (3) or a stretched plate fixed to the other end of the shaft by the intervention of an axle and encased in the shaft to allow the passage in the hole of the plates, and a nut (4) of steel forged on the threaded shaft and allowing the locking. The drilled part may end in a lever allowing its passing to the vertical position from the horizontal position. USE - Allows transfer and extraction of elements from the ground such as plates, grilles or other articles.

Description

TITRE DE L'INVENTION
Système d'encrage permettant d'extraire et déplacer des éléments encastrées dans le sol tels que plaques d'égouts, grilles, ou toutes autres pièces existant actuellement sur le marché.TITLE OF THE INVENTION
Inking system for extracting and moving elements embedded in the ground such as manhole covers, grates, or any other parts currently existing on the market.

La présente invention conceme un système d'ancrage pour extraire et déplacer des eléments encastres dans le sol tels que plaques d'égouts, grilles, ou toutes autres pièces, soit à trou central ou exentré, s'adaptant rapidement et offrant toute garantie de sécurité.The present invention relates to an anchoring system for extracting and moving elements embedded in the ground such as manhole covers, grids, or any other parts, either with central or eccentric hole, adapting quickly and offering any guarantee of security. .

Le décollement de ces tampons est traditionnellement effectué par des employés de la ville à l'aide d'une barre à mine ou d'un crochet marteau.The removal of these pads is traditionally carried out by city employees using a crowbar or a hammer hook.

Certaines de ces interventions nécessitent un tel effort, qu'elles entraînent des accidents de colonne vertébrale avec anêt de travail.Some of these interventions require such an effort that they lead to spinal accidents with work stoppage.

Le système inventé permettra de supprimer ce genre d'accident.The invented system will eliminate this kind of accident.

Les figures 1 et 2 représentent une réalisation d'un système selon l'invention.Figures 1 and 2 show an embodiment of a system according to the invention.

II est constitué d'une tige (1) spéciale filetée, à une extrémitée: un anneau de forme (2) ergonomique, en acier ou plastique, fixé par un manchon spécial. It consists of a special threaded rod (1), at one end: a ring of ergonomic shape (2), made of steel or plastic, fixed by a special sleeve.

A l'autre extrémité: est fixé un étiré plat d'une résistance de 80 kg au mm2, s'encastrant dans la tige pour permettre le passage dans le trou des plaques, il est fixe par l'intermédiaire d'un axe de forme oblique; à la place de cet étiré peut éfre mis une pièce fraisée de (3) forme cylindrique, pleine d'un côté, évidée de l'autre et terminée par une lèpre permettant le passage de la position verticale à la position horizontale.At the other end: is fixed a flat stretched with a resistance of 80 kg per mm2, fitting into the rod to allow the passage in the hole of the plates, it is fixed via a form axis oblique; in place of this stretched can be put a milled part of (3) cylindrical shape, full on one side, hollowed out on the other and terminated by a leprosy allowing the passage from the vertical position to the horizontal position.

Sur la tige spéciale filetée se trouve un écrou en acier forge (4) permettant le blocage et le maintien lors du déplacement. On the special threaded rod there is a forged steel nut (4) allowing locking and holding during movement.
