Foldable rescue trailer with folding-unfolding guide rails

Abstract

The invention designs a foldable rescue trailer with folding-unfolding guide rails. The foldable rescue trailer comprises a collection frame and a trailer unit, a winch is mounted on the collection frame which is mounted in a carriage of a rescue vehicle, and the trailer unit comprises a main beam, folding beams, transverse beams, wheel carriers and trailer wheels. A crossbeam gas springs with control switches are mounted on the folding beams and drive the cross beams to be unfolded. The folding-unfolding guide rails are arranged on the collection frame, rotating shafts are arranged on two sides of the head end of the main beam, a main beam groove is reserved between the folding-unfolding guide rails, two side walls of the main beam groove are provided with rotating shaft slide ways matched with rotating shafts, and the rotating shafts of the main beam are embedded in the rotating shaft slide ways to slide when the trailer unit is folded or unfolded. The foldable rescue trailer with folding-unfolding guide rails has the advantages that the foldable rescue trailer can be completely folded in a normal vehicle in general size, unfolding timing of the cross beams can be controlled by the cross beam gas springs with the control switches, and owing to guiding of the folding-unfolding guide rails in folding and unfolding of the trailer, manual operation procedures are reduced, and operating intensity is greatly relieved for operators.
