The specific embodiment
As shown in Figure 1,2 and 3, a kind of folding breakdown trailer, comprises storage frame 1 and trailer unit, in storage frame 1, capstan winch 2 is installed, and storage frame 1 is arranged in breakdown lorry compartment.
Trailer unit comprises girder 3, folded beam 4, crossbeam 5, wheel holder 6 and trailer wheels 7.
The head end of girder 3 is provided with the connector 8 for being connected with the tow ball of breakdown lorry, one end of the other end of girder 3 and folded beam 4 is hinged, between girder 3 and folded beam 4, arrange and promote the folded beam gas spring 9 that folded beam 4 launches, the both sides of folded beam 4 have the crossbeam 5 hinged with folded beam 4, wheel holder 6 has two, two wheel holders 6 are arranged on crossbeam 5, and lay respectively at the both sides of folded beam 4, and trailer wheels 7 is arranged in wheel holder 6.
The head end of girder 3 is connected by separable rotary position limiting structure with storage frame 1, and separable rotating and limiting mechanism comprises the rotary axis groove 11 of the opening in rotating shaft 10 and the storage frame 1 being fixed on girder 3, and rotating shaft 10 embeds rotary axis groove 11 and rotates.
On folded beam 4, there is hauling rope 12 traction wheel 13 and the folding crossbeam mechanism of folding girder 3, folded beam 4 and crossbeam 5 simultaneously that utilizes capstan winch 2, folding crossbeam mechanism comprises folding connecting rod 14, screw mandrel 15 and screw 16, one end of folding connecting rod 14 and crossbeam 5 are hinged, the other end of folding connecting rod 14 and screw 16 are hinged, and traction wheel is by driving bindiny mechanism to drive screw mandrel 15 to rotate.
In order to utilize better traction wheel 13 rotatablely moving when the folded beam 4, prevent from skidding, traction wheel 13 is sprocket wheel, the leading portion of the hauling rope 12 on capstan winch 2 is chain-type hauling rope.
Wheel holder 6 is arranged on crossbeam 5 slippingly, on folded beam 4, there is the connecting rod rack 17 stretching out to folded beam 4 both sides, between wheel holder 6 and connecting rod rack 17, connect by driven wheel holder 6 wheel holder connecting rod 18 of slippage on crossbeam 5, one end of wheel holder connecting rod 18 is hinged with wheel holder 6, and the other end and the connecting rod rack 17 of wheel holder connecting rod 18 are hinged.
Dispose procedure is as follows:
