Description
Appareil pour le levage des matériaux de construction. L'invention, a pour objet un appareil pour le levage des. matériaux de construction, notamment pour les travaux -de drainage. Il est destiné à faciliter la manutention des matériaux, en particulier des canaux en béton utilisés. pour établir des regards de visites (cheminées) sur collecteurs.
La manutention de canaux d'un poids relativement élevé est facilitée du: fait que -des attaches peu sûres, ,gênantes. et coûteuses sont évitées, et l'emboî tage des canaux peut. se faire directement, d'où économie -de main-,d'oeuvre.
Le dessin ci-joint montre, à titre d'exem ple, une forme d'exécution .de -cet appareil. La fig. 1 est une vue -de face et la fig. 2 est une vue par-dessus.
Deux flasques <I>A et A'</I> reliés entre eux par des entretoises M-H'-M" forment un bâti qui porte à ses. deux extrémités des mar- daches <I>P et</I> P' respectivement dont la partie extérieure est .striée afin de présenter un appui rugueux;
lesdites mordaches P et<B>'</B> de forme excentrique pivotent sur des. tourillons C et C' respectivement -et se prolongent cha cune par l'un des deux bras -de levier B et B' dont les, extrémités. sont reliées au moyen de tourillons D et D' à des leviers E et E';
ces leviers E et<B>E</B> se rejoignent à leur extrémité supérieure par un tourillon H fixé .dans une pièce I qui comporte une boucle pour l'atta che du eârble du moufle de levage.
Par le jeu des leviers, la traction @du câble sur la bouille I oblige les mordaches <I>P et P'</I> à pivoter sur les tourillons C et C' et 'leur forme excentrique produit un coincement contre la paroi inté rieure du canal, et cela d'autant plus puis samment que le poids de ce 4ernîer est plus grand.
Les portées d'emboîtement restent libres et peuvent en conoéquence permettre de juxtaposer les canaux sans difficûlté.
Device for lifting construction materials. The invention relates to an apparatus for lifting. building materials, especially for drainage works. It is intended to facilitate the handling of materials, in particular the concrete channels used. to establish inspection manholes (chimneys) on collectors.
The handling of channels of a relatively high weight is facilitated by: the fact that -secure fasteners,, annoying. and expensive are avoided, and the fitting of the channels can. be done directly, hence saving - of labor - of labor.
The accompanying drawing shows, by way of example, an embodiment of this apparatus. Fig. 1 is a front view and FIG. 2 is a top view.
Two flanges <I> A and A '</I> interconnected by spacers M-H'-M "form a frame which carries at its two ends brackets <I> P and </I> P 'respectively whose outer part is .striée in order to present a rough support;
said jaws P and <B> '</B> of eccentric shape pivot on. journals C and C 'respectively -and are extended each by one of the two lever arms B and B' whose ends. are connected by means of pins D and D 'to levers E and E';
these levers E and <B> E </B> are joined at their upper end by a pin H fixed. in a part I which has a loop for attaching the eârble of the lifting block.
By the play of the levers, the traction @ of the cable on the nozzle I forces the jaws <I> P and P '</I> to pivot on the pins C and C' and their eccentric shape produces a wedging against the internal wall. higher of the canal, and all the more so as the weight of this last is greater.
The interlocking spans remain free and can therefore make it possible to juxtapose the channels without difficulty.
