Title (EN) REPLACEABLE FASTENER FOR COVER PLATES AND THE LIKE
(FR) DISPOSITIF DE FIXATION REMPLACABLE POUR PLAQUES DE COUVERTURE ET SIMILAIRES
Abstract: front page image
(EN)The push frame (12) of a tractor-scraper (10) normally has a plurality of cover plates (14) releasably secured therebelow to provide access internally of the push frame. In standard practice, the cover plates are secured to the push frame by a plurality of bolts and the heads of the bolts are subjected to wear and possible breaking-off due to their exposure upon operation of the tractor-scraper. This invention provides a mounting assembly (13) for expeditiously removing and replacing the cover plates upon wearing or breaking-off of the heads (19) of bolts (18) thereof by providing an internally and externally threaded bushing (24) which is threadably connected on the push frame and is further threadably connected to each bolt. Thus, a workman need only engage the bushing with a socket wrench or the like to release the bolt and thus the cover plate upon wearing or breaking-off of the heads of the bolts.
(FR)Le chassis de poussee (12) d"un engin de terrassement (10) possede normalement une pluralite de plaques de couverture (14) fixees de maniere demontable pour permettre l"acces a l"interieur du chassis de poussee. Dans la pratique habituelle, les plaques de couverture sont fixees au chassis de poussee par une pluralite de boulons et les tetes des boulons sont sujettes a une deterioration par l"usure et a de possibles ruptures a cause de leur exposition lors du fonctionnement de l"engin. La presente invention prevoit un ensemble de montage (13) permettant d"enlever et de remplacer rapidement les plaques de couverture en cas d"usure ou de rupture des tetes (19) des boulons (18) en utilisant une douille (24) filetee a l"interieur et a l"exterieur se fixant au moyen de filetages au chassis de poussee et a chaque boulon. Un ouvrier n"aura ainsi qu"a serrer la douille avec une cle pour liberer le boulon et, donc, la plaque de couverture en cas d"usure ou de rupture des tetes des boulons.
