Abstract

1. A crane wagon provided with a platform and a movable counter weight device (6), wherein said counter weight device (6) is mounted underneath the platform at the level of the crane and is movable in a direction perpendicular to the track, so that in its extreme positions, said counter weight device does not engage the circulation clearance gauge of the wagon.

Description

L'invention concerne les wagons-grues utilisés pour la manutention et la pose de matériels encombrants, tels que des aiguillages, des tabliers de pont, etc.The invention relates to crane wagons used for the handling and installation of bulky equipment, such as switches, bridge decks, etc.

Les grues de ces wagons travaillent perpendiculairement à la voie. Il en résule, en charge, un mouvement de basculement indésirable de la plateforme du wagon, puisque pour des raisons de stabilité et de sécurité, il est nécessaire que la plateforme soit parallèle au plan de la voie.The cranes in these cars work perpendicular to the track. This results in load, an undesirable tilting movement of the platform of the wagon, since for reasons of stability and safety, it is necessary that the platform is parallel to the plane of the track.

Actuellement, pour obtenir ce parallélisme, on bloque de façon empirique la plateforme par rapport aux essieux ou bogies en plaçant manuellement des cales entre les essieux ou bogies et la plateforme.Currently, to obtain this parallelism, the platform is empirically blocked with respect to the axles or bogies by manually placing shims between the axles or bogies and the platform.

D'autre part, dans les wagons grues connus, on est obligé, pour augmenter la portée des grues en fonction de la charge, d'ajouter, à l'opposé de la flèche, des contrepoids qui engagent le gabarit de circulation.On the other hand, in known crane wagons, it is necessary, in order to increase the range of the cranes as a function of the load, to add, opposite the boom, counterweights which engage the circulation gauge.

La présente invention a pour but de procurer des moyens améliorés pour assurer le parallélisme de la plateforme en fonction de la charge portée par la ou les grues en restant dans les limites du gabarit de circulation.The object of the present invention is to provide improved means for ensuring the parallelism of the platform as a function of the load carried by the crane or cranes while remaining within the limits of the traffic gauge.

Selon l'invention, sous la plateforme du wagon, au niveau de la grue, est monté un contrepoids déplaçable selon une direction perpendiculaire à la voie.According to the invention, under the platform of the wagon, at the level of the crane, is mounted a counterweight movable in a direction perpendicular to the track.

Selon une caractéristique préférée de l'invention, le contrepoids est monté coulissant dans des glissières fixées sous le plateau du wagon.According to a preferred characteristic of the invention, the counterweight is slidably mounted in slides fixed under the platform of the wagon.

Selon une autre caractéristique de l'invention, le déplacement du contrepoids est commandé par une vis sans fin entraînée en rotation par un moto-réducteur.According to another characteristic of the invention, the movement of the counterweight is controlled by an endless screw driven in rotation by a gear motor.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, d'un exemple non limitatif de réalisation d'un wagon conforme à l'invention. La description sera faite en référence au dessin annexé qui représente une vue en coupe schématique partielle d'un wagon-grue conforme à l'invention prise transversalement par rapport à la plate-forme.Other characteristics and advantages of the invention will emerge from the description which follows, of a nonlimiting example of embodiment of a wagon in accordance with the invention. The description will be made with reference to the accompanying drawing which shows a partial schematic sectional view of a crane wagon according to the invention taken transversely with respect to the platform.

Le wagon-grue selon l'invention est constitué par une plateforme 1 montée sur deux essieux ou bogies non représentés. Ladite plateforme porte au moins une grue 2, montée sur une tourelle 3 et munie de manière usuelle d'un contrepoids 4. Le wagon repose sur des rails 5.The crane wagon according to the invention consists of a platform 1 mounted on two axles or bogies not shown. Said platform carries at least one crane 2, mounted on a turret 3 and usually provided with a counterweight 4. The wagon rests on rails 5.

Sous la plateforme 1, au niveau de la grue 2 est disposé un contrepoids 6, qui peut se déplacer transversalement par rapport à la voie d'un bord à l'autre de la plateforme 1 (flèche A). A cet effet, le contrepoids est monté sur des glissières 7. Le mouvement du contrepoids est commandé par une vis sans fin 8, entraînée en rotation par un moto-réducteur 9.Under the platform 1, at the level of the crane 2 is disposed a counterweight 6, which can move transversely relative to the track from one edge to the other of the platform 1 (arrow A). To this end, the counterweight is mounted on slides 7. The movement of the counterweight is controlled by an endless screw 8, driven in rotation by a geared motor 9.

Le contrepoids peut être déplacé depuis une position centrale neutre, représentée en pointillé vers deux positions extrêmes sur l'un ou l'autre des bords de la plateforme, sans engager le gabarit de circulation.The counterweight can be moved from a neutral central position, shown in dotted lines to two extreme positions on either of the edges of the platform, without engaging the circulation gauge.

Cette caractéristique est particulièrement avantageuse, car elle assure une sécurité absolue d'utilisation de la machine.This characteristic is particularly advantageous because it ensures absolute safety in the use of the machine.

L'utilisation d'un contrepoids mobile, outre le fait qu'il supprime l'obligation de bloquer la plateforme sur les essieux ou bogies, permet d'augmenter considérablement la charge de la grue, en fonction de sa portée.The use of a mobile counterweight, in addition to the fact that it eliminates the obligation to block the platform on the axles or bogies, makes it possible to considerably increase the load of the crane, according to its range.

A titre indicatif, cette augmentation est illustrée dans le tableau ci-dessous pour le déplacement d'un contrepoids de 11 t, sur une distance de 1 m, par rapport à sa position neutre.

Figure imgb0001
As an indication, this increase is illustrated in the table below for the displacement of an 11 t counterweight, over a distance of 1 m, relative to its neutral position.
