Fixed support is installed on the relief car afterbody, and an end is connected with girder end before the collapsible girder.The capstan winch that is fixed on the relief car is connected with rear girder with pulley by cable.The utility model can be realized folding and the expansion of forward and backward girder by a pair of air spring, organizes work when realizing traction, and during no traction work, the folding trailer is convenient to be collected in the breakdown lorry.
For make expansion forward and backward girder between have stable annexation, prevent automatic folding, on rear girder and the front girder pin-and-hole is set respectively, and arranges and fixed pin shaft that this pin-and-hole is adaptive.Can by bearing pin and forward and backward girder pin-and-hole reach fixing purpose.
The support bracket fastened rear end of the utility model is provided with oblique slideway, and the front end of oblique slideway is provided with limiting block, and the positioning joint that cooperates with limiting block is set on preceding girder.Can be conveniently trailer be pulled out and launched in the rescue car body by oblique slideway, by the cooperation of limiting block and positioning joint, be beneficial in the rescue car body of the trailer location after the folding.
In addition, arranging on the rear girder can be along the slide block of back rest axially reciprocating, two connecting rods of slide block hinge joint, and the hinged crossbeam of the other end of each connecting rod, described bucket and automatic steering wheel are connected on this crossbeam.By the reciprocal driving power device that is connected with slide block, can drive crossbeam folding, expansion by slide block, be beneficial to the width of the trailer that further dwindles folding, be beneficial to the littler rescue car body of width.
Dwindle for progressive, described crossbeam arranges slide rail, and the front end of described bucket is engaged on the slide rail, links connecting rod on the bucket, and the other end of connecting rod is hinged on the support, and support is fixed in the rear end of rear girder.By the reciprocating action of slide block, can realize realizing synchronously that bucket and automatic steering wheel move back and forth at crossbeam.
The utility model also arranges one group of through hole in the end of support, another group through hole is set in the end of connecting rod, and the bearing pin of cooperation is set between two groups of through holes.Can by this cooperate of bearing pin and two groups of through holes, regulate the spacing between a pair of bucket, with the spacing between two automatic steering wheels that adapt to different towed vehicles.
The rear end of the utility model bucket also arranges the elasticity chock.Can push the elasticity chock earlier when the wheel that is dragged vehicle is dragged the wheel bucket, the chock resilience supports and is dragged vehicle then, makes and is dragged vehicle firmly to be supported on the utility model.
The bucket rear end arranges trundle.When forward and backward girder was unfolded, trundle landed earlier, frustrated after making bucket, and automatic steering wheel lands prior to bucket, is beneficial to the protection bucket.
In addition, two automatic steering wheels are hinged and connected on two buckets by bearing pin respectively, at two buckets difference fixed oil cylinders, the inboard of two automatic steering wheels is hinged on respectively on the expansion link of two oil cylinders, and the oil inlet and outlet of two oil cylinders seals serial connection mutually by flexible pipe.Two steering link to each other, and form a loop, make the motion of any one automatic steering wheel all will pass to synchronously another automatic steering wheel.
