Pneumo-hydraulic system for repairing transportation containers

摘要

An apparatus used to repair damage from metal body panels of a transportation container. The apparatus includes a platform having wheels that can optionally be locked. The apparatus further includes a pivoting arm that can be selectively raised, lowered, extended or retracted to repair virtually any area of a transportation container. At the end of the pivoting arm is a cross-arm member comprised of a piston repair arm that can be fitted with a plurality of attachments depending on the contours of the surface being repaired. The area to be repaired can include perimeter walls, ceilings, doorframes, and/or corner posts. The pivoting arm and piston repair arm are driven using a pneumo-hydraulic system that is lighter than any other system currently used on transportation repair devices. The substantial reduction in weight allows the apparatus to readily enter transportation containers and be easily handled by a single operator.

主权项

1. An apparatus used to repair transportation containers, comprising:
a) a platform; b) a fixed vertical structural member mounted to said platform, said fixed vertical member hingedly mounted to a telescopic pivoting arm, said telescopic pivoting arm being able to raise and lower to a predetermined height as well as able to extend or retract a predetermined distance; c) a cross-arm member mounted to the distal end of said pivoting arm, said cross-arm member including a first tubular member having a repair member at its distal end that is gradually pushed against surfaces of said transportation containers to repair dents or similar damage, said cross-arm member further including a second tubular member opposite to said first tubular arm, said second tubular arm includes a support member at its distal end to engage the surface opposite the surface being repaired thereby providing support and stability to said apparatus; d) a ratably mounted sleeve member mounting said cross-arm member to said pivoting arm, said rotably mounted sleeve member includes a sleeve extension inserted into a housing located at the distal end of said telescopic pivoting arm that allows said cross-arm member to be rotated about a 360 degrees axis with respect to said pivoting arm; e) fastening means to secure said cross-arm member in a predetermined position; g) a removable pneumo-hydraulic assembly including at least one hydraulic tank, two hydraulic pedals and a plurality of hoses to provide driving means to said pivoting arm's articulations and said first tubular arm, said pneumo-hydraulic assembly detachable from said platform so that said apparatus is more easily transported and so that said pneumo-hydraulic assembly is more ergonomically maintained and repaired; h) an air pressure input means to receive pressurized air from an external source, said input means being connected to said pneumo-hydraulic assembly, whereby said air pressure input means drives said pneumo-hydraulic assembly; and i) a control unit allowing a user to selectively adjust the height or extension of said pivoting arm or the extension of said first tubular arm.
