Detailed description of the invention
As shown in Fig. 1,2,3,4 and 5, a kind of folding breakdown trailer device launching by air spring, comprises storage machineFrame 1 and trailer unit, be provided with capstan winch 2 in storage frame 1, and storage frame 1 is arranged in breakdown lorry compartment, trailer unit bagDraw together girder 3, folded beam 4, crossbeam 5, wheel holder 6 and trailer wheels 7, the head end of girder 3 be provided with for the tow ball of breakdown lorryThe connector 8 connecting, the other end of girder and one end of folded beam are by being separately fixed at the girder hinge on girder and folded beamRelay part and folded beam hinge member are hinged, arrange and promote the folded beam gas bullet that folded beam 4 launches between girder 3 and folded beam 4Spring 9, the both sides of folded beam 4 have the crossbeam 5 hinged with folded beam 4, and wheel holder 6 has two, and two wheel holders 6 are arranged on crossbeam 5,And laying respectively at the both sides of folded beam 4, 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, separable rotary spacing machineStructure 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 turnsMoving.
On folded beam 4, have and utilize the folding girder 3 of pull rope 12 of capstan winch 2, the traction wheel 13 of folded beam 4.
The crossbeam air spring 19 with gauge tap that drives crossbeam 5 to open, crossbeam air spring 19 are installed on folded beam 4Telescopic end is connected with crossbeam 5 by folding connecting rod 14, and the gauge tap of crossbeam air spring 19 is by being fixed on girder hinge memberOn cam 20 control and open opportunity. When the shape of boss ensures that crossbeam is completely folding the gauge tap of crossbeam air spring 19 inRelease conditions, crossbeam can keep folded state by crossbeam air spring 19.
Wheel holder 6 is arranged on crossbeam 5 slippingly, has the connecting rod rack stretching out to folded beam 4 both sides on folded beam 417, between wheel holder 6 and connecting rod rack 17, connect wheel holder connecting rod 18 by driven wheel holder 6 wheel holder connecting rod 18 of slippage on crossbeam 5One end hinged with wheel holder 6, the other end and the connecting rod rack 17 of wheel holder connecting rod 18 are hinged.
Dispose procedure is as follows:
Capstan winch 2 discharges pull rope 12, and folded beam 4 is slowly opened under the effect of folded beam air spring 9; 4 dozens of folded beamsOpen to a certain degree time, the cam 20 on girder hinge member is pressed the gauge tap of sill air spring 19, makes crossbeam air spring19 work, open crossbeam 5; After trailer unit is opened completely, take out the pull rope 12 being enclosed within on traction wheel 13, can be pulled outwardlyGo out trailer unit, connector is buckled on tow ball. In wheel holder 6, set up springboard, accident, fault vehicle draw by capstan winch 2On take turns holder 6, complete whole trailer loading process.
The process of folding trailer unit is as follows:
First pull rope 12 is enclosed within on traction wheel 13, the drag hook of the head end of pull rope 12 is hooked in storage frame 1, will connectJoint 8 and tow ball release, mention connector 8, and girder 3 is pulled in breakdown lorry compartment, and the rotating shaft 10 of girder 3 is snapped in canThe rotary axis groove 11 of rotary position limiting structure separating, capstan winch 2 tightens up pull rope 12, and pull rope 12 starts to make 3 grams of folded beam 4 and girdersThe active force that takes folded beam air spring 9 is slowly folding, is folded to a certain degree the cam on girder hinge member at folded beam 420 while supressing the gauge tap of crossbeam air spring 19, manually folding crossbeam 5; Capstan winch 2 works on, until folded beam 4, girder3 is completely folding, and the release control switch in the time that folded beam 4, girder 3 are completely folding of the cam 20 on girder hinge member, makesThe 19 not flexibles of crossbeam air spring.
