Abstract

The cable (2) is wound onto the drum (1) running on the central shaft (3). The drum is fitted with a stop (B2) which comes into contact with the flat face of the cam (4) mounted on the shaft. The lever on the shaft is attached at its outer end to the spring (R) which is fixed to the drum at the opposite end. The weight (6) is suspended from the cable (2). Slack in the cable is taken up by rotating the drum in the clockwise direction (F1) under the action of the spring. As the cable tightens again the stop returns to the position (B2).

Description

L'invention a pour objet un - dispositif pour rattraper le mou de câble d'un câble hydroporteur pour dégrilleur. The invention relates to a - device for catching the slack in the cable of a water-borne cable for screen.

Actuellement, pour rattraper le mou de câble dans un dégrilleur, on utilise un rattrapeur de câble à contrepoids ou à bascule. Ces dispositifs sont très encombrants et ce, d'autant plus pour des dégrilleurs de grande taille. I1 existe, dans ces dispositifs actuels, un effort permanent de la roue ou du galet à une grande pression qui est fonction du poids de câble à relever. L'usure du câble ou des galets est relativement rapide. Currently, to catch the slack in a screen, we use a cable counterweight or rocker. These devices are very bulky and this is all the more so for large screens. I1 exists, in these current devices, a permanent effort of the wheel or the roller at a high pressure which is a function of the cable weight to be raised. Cable or roller wear is relatively quick.

Enfin, ces dispositifs ne sont pas adaptés dans le cas où l'on utilise des câbles hydroporteurs qui ont des caractéristiques techniques propres tels que des rayons de courbure, etc....Finally, these devices are not suitable in the case where water-carrying cables are used which have their own technical characteristics such as radii of curvature, etc.

L ' invention évite tous ces inconvénients. The invention avoids all these drawbacks.

Elle permet do rattraper le mou d ' un ou des câbles hydroporteurs du chariot lorsque celui-ci rencontre un obstacle lors de sa descente le long de la grille. It allows you to catch the slack of one or more water carrier cables of the carriage when the latter encounters an obstacle when it descends along the grid.

Le dispositif selon l'invention est composé d'un ressort de rappel disposé entre un point d'accrochage avec le tambour d'enroulement du câble hydroporteur et son arbre d ' entrainement, ledit arbre comportant une canne d 'appui qui coopère avec une butée de réglage de la course de rattrapage disposée sur ledit tambour. The device according to the invention is composed of a return spring disposed between a point of attachment with the winding drum of the water-carrying cable and its drive shaft, said shaft comprising a support rod which cooperates with a stop adjusting the take-up stroke arranged on said drum.

La figure jointe permettra aisément de comprendre 1 'inven- tion. Elle représente un mode de réalisation préféré selon 1 'in- vention. The attached figure will make it easy to understand the invention. It represents a preferred embodiment according to the invention.

Le tambour d ' enroulement 1 porte le ou les câbles hydropor tueurs 2. Sur l'arbre 3 est monté une canne d'appui 4 de l'arbre 3 qui coopère avec une butée 5 de réglage de la course du rattrapage du mou de câble 2. 6
La masse ou le poids /représente le poids du rateau du dégrilleur qui est au bout du câble hydroporteur 2. Si le rateau ou une de ses extrémités rencontre un obstacle, il y a immédiatement du mou sur le câble 2, ce mou est rattrapé par un quart de tour environ dans le sens indiqué par la flèche F1, c'est en fait le ressort de rappel R qui réenroule le câble 2 quand le poids 6 de la poche ou du rateau a disparu ou diminué notablement par rapport à la force de rappel dudit ressort R, autour du tambour d'enroulement 1. Le ressort R vient en position R1,
B la butée de réglage/est en position B1, le tambour ayant tourné d'un quart de tour dans le sens de la flèche F1.The winding drum 1 carries the hydropor killer cable or cables 2. On the shaft 3 is mounted a support rod 4 of the shaft 3 which cooperates with a stop 5 for adjusting the stroke of the take-up of the cable slack 2.6
The mass or weight / represents the weight of the screen rake which is at the end of the water carrier cable 2. If the rake or one of its ends encounters an obstacle, there is immediately slack on the cable 2, this slack is caught by about a quarter of a turn in the direction indicated by the arrow F1, it is in fact the return spring R which rewinds the cable 2 when the weight 6 of the pocket or of the rake has disappeared or decreased notably with respect to the force of return of said spring R, around the winding drum 1. The spring R comes into position R1,
B the adjustment stop / is in position B1, the drum having turned a quarter of a turn in the direction of arrow F1.

Si le poids 6 de la poche ou du rateau apparaît à nouveau au niveau du câble hydroporteur 2, il tend le ressort R en position R2, la canne d'appui 4 vient buter contre la butée B qui est alors en position B2 après avoir effectue un quart de tour dans le sens indique par la flèche F 2.  If the weight 6 of the pocket or the rake appears again at the level of the water-carrier cable 2, it tends the spring R in position R2, the support rod 4 abuts against the stop B which is then in position B2 after having performed a quarter turn in the direction indicated by the arrow F 2.

Le ressort de rappel R a une force de rappel beaucoup plus faible que le poids 6 de la poche Par exemple, si la poche ou le rateau pèse 5.000 ktlogrammes, le ressort de rappel peut avoir une force de 450 kilogrammes.  The return spring R has a return force much weaker than the weight 6 of the pocket. For example, if the pocket or the rake weighs 5,000 ktlograms, the return spring can have a force of 450 kilograms.
