CA 2129889

A foldable wheeled stand is provided for supporting a motor driven pipe threading machine during operation thereof and for transporting the machine from one location to another. The stand includes a scissors-type leg assembly having lower ends which engage an underlying surface when the stand is both folded and unfolded and having upper ends which are respectively elevated and lowered relative to the support surface when the stand is in its unfolded and folded positions. A pipe threading machine is mounted between the upper ends of the stand for pivotal displacement about one of the upper ends and for sliding displacement relative to the other, during the displacement of the stand and machine between the folded and unfolded positions of the stand. A bracket arrangement secures the threading machine to the stand in each of the folded and unfolded positions thereof, and a pair of gas springs are interposed between legs of the stand to counterbalance the weight of the threading machine during displacement of the stand between the folded and unfolded positions thereof.

Établi repliable monté sur roues utilisé pour déplacer une machine à fileter des tuyaux d'un emplacement à un autre et pour supporter celle-ci pendant le filetage des tuyaux. L'établi comporte un piétement de type à ciseaux, dont les extrémités inférieures viennent en prise avec une surface sous-jacente, que l'établi se trouve en position repliée ou non, et dont les extrémités supérieures peuvent être relevées ou abaissées par rapport à la surface de support, que l'établi se trouve en position repliée ou non. Une machine à fileter les tuyaux est montée entre les extrémités supérieures de l'établi, en pivotement autour de l'une des extrémités et en coulissement par rapport à l'autre au cours des déplacements de l'établi et de la machine. Un support d'assemblage retient la machine à fileter à l'établi, et une paire d'amortisseurs à gaz sont interposés entre les pattes de l'établi pour contrebalancer le poids de la machine à fileter au cours des déplacements.
