The specific embodiment
Further illustrate technical scheme of the present invention below in conjunction with drawings and Examples.
Please in conjunction with shown in Fig. 1, Fig. 2, Mini road dragging wrecker 100 of the present invention comprises small-sized traction power car 110 and is located at the collapsible draw gear 120 of power car 110 afterbodys, small-sized traction power car 110 can adopt the dillies such as four wheel drive motor (ATV), it is little that such vehicle has a volume, horsepower foot, the advantages such as towability is strong, turn radius is little, good operation performance have alerting ability and crossing ability preferably on crowded urban highway and narrow street.Collapsible draw gear 120 comprises containing box 130, fold mechanism 140, lifting mechanism 150, wheel holding mechanism 160 and traction wheel 170, and containing box 130 is located at power car 110 afterbody upper ends, for taking in the draw gear 120 after folding; Fold mechanism 140 1 ends and power car 110 are hinged, and lifting mechanism 150 and wheel holding mechanism 160 all are located at fold mechanism 140 other ends, and traction wheel 170 is connected with lifting mechanism 150.Concrete structure is as follows: fold mechanism 140 comprises longeron 141, forward and backward tie-beam 142,143, left and right crossbeam 144,145, Foldable hydraulic cylinder 146 and electronic reel (not shown), and longeron 141 1 ends and power car 110 afterbody after-frames are hinged; Front tie-beam 142 is hinged with longeron 141, and rear tie-beam 143 is hinged with front tie-beam 142; Left and right crossbeam 144,145 is located at the both sides of rear tie-beam 143, and by folding connecting rod 147 is set, with rear tie-beam 143, is hinged respectively; Foldable hydraulic cylinder 146 is located on rear tie-beam 143, and is hinged with folding connecting rod 147, for driving folding connecting rod 147 rotations, thereby can drive left and right crossbeam 144,145, folds or launches; Electronic reel is located on power car 110, and is connected with longeron 141 by hauling rope, in order to control packing up or putting down of longeron 141.Lifting mechanism 150 comprises lifting bracket 151 and lifting hydraulic cylinder 152, and lifting bracket 151 is hinged respectively is located at left and right crossbeam 144,145 two side ends; Lifting hydraulic cylinder 152 is hinged being located on lifting bracket 151 respectively, in order to drive lifting bracket 151 rotations.Wheel holding mechanism 160 comprises wheel holding arm 161 and wheel holding hydraulic actuating cylinder 162, and wheel holding arm 161 is located between lifting mechanism 150, and is located at respectively on left and right crossbeam 144,145; Wheel holding hydraulic actuating cylinder 162 is located at respectively on left and right crossbeam 144,145, and an end is hinged with corresponding wheel holding arm 161, in order to drive 161 rotations of wheel holding arm, thereby can make wheel holding arm 161 embrace respectively the front-wheel of fault vehicle.Traction wheel 170 is located at respectively on turning rack 171, and forms an eccentric throw with the center of gyration of turning rack 171, in order to follow power car 110, realizes follow-up steering.Turning rack 171 is connected and fixed with lifting bracket 151, and can be with lifting bracket 151 upsets; Also be provided with synchronous brake 172 on traction wheel 170, can carry out synchronous braking with small-sized traction power car 110.This wrecker 100 comprises car-mounted computer control system (not shown), with electronic reel and each hydraulic actuating cylinder, is electrically connected to respectively, in order to startup and the stroke of accurate Calculation and the moving reel of automatic control electric and each hydraulic actuating cylinder.This wrecker 100 also comprises the Digiplex (not shown), can, to car-mounted computer control system emission wireless control signal, in order to carry out wireless operated in safety zone, improve safety.
The principle of work of the collapsible draw gear 120 of this wrecker 100 is as follows:
Before using, draw gear 120, in folding full reduced state, is placed in the containing box 130 of traction power car 110 after-frame tops.During use, first utilize the deadweight (the deviation of gravity center strong point) of draw gear 120, handle the onboard wireless remote controller, by electronic reel, discharge slowly hauling rope, longeron 141 is lowered into vertical surface and is approximately 30 ° of angles (with traction power car 110 after-frames, not interfere and to be advisable); Then control Foldable hydraulic cylinder 146 and shrink, Foldable connecting rod 147 moves, and then causes the Unscrew of left and right crossbeam 144,145 and lifting bracket 151, thereby realizes the expansion action of draw gear 120; Continue to discharge lentamente again the rope of electronic reel, by the deadweight of draw gear 120 and the rolling on traction wheel 170 and ground, left and right crossbeam 144,145 and lifting bracket 151 are launched fully, horizontal on the ground; Now drive 110 reversings of traction power car, shift wheel holding arm 161 onto fault vehicle front-wheel position, and control wheel holding hydraulic actuating cylinder 162 driving wheel holding arms 161 and block respectively corresponding front-wheel; And then control lifting hydraulic cylinder 152 and stretch out, make lifting bracket 151 clickwises, and then left and right crossbeam 144,145 and whole wheel holding mechanism 160 are lifted thereupon, thereby the front-wheel of fault vehicle is lifted, can be drawn, be hauled operation.
Adopt the small-sized traction power cars 110 such as ATV, advantages such as both having retained its powerful, be applicable to multiple landform, towability is strong, operating characteristic is excellent, crossing ability is good, can meet again the arrangement space needs of collapsible draw gear 120 and hydraulic power system thereof.Control by calculating, under the drive of Foldable hydraulic cylinder 146, can accurately realize auto-folder and the expansion action of similar " the folded umbrella formula " of whole folded formula draw gear 120.Drive wheel holding arms 161 and realize automatically holding tightly of fault vehicle front-wheel to being hauled by being arranged in wheel holding hydraulic actuating cylinder on left and right crossbeam 144,145 162.And the hinge of lifting mechanism 150 and lifting bracket 151 is optimized reasonable Arrangement through numeral, keeping, under the prerequisite that lifting mechanism 150 sizes are less, can improving to greatest extent hoisting force.Lifting hydraulic cylinder 152 is hidden in lifting mechanism 150 inside, and not only compactness simple for structure, and its hydraulic cylinder piston rod can exempt to be damaged or pollutes, and its hydraulic power pumping plant is regulated lifting speed by governor valve in addition, realizes folded formula draw gear 120 synchronous liftings.Traction wheel 170 forms an eccentric throw with the center of gyration of turning rack 171, in order to follow power car 110, realizes follow-up steering.Can full automaticity realize the actions such as folding, expansion, wheel holding, lifting by the car-mounted computer control system.Whole control system can also have the several functions such as operation locking, fault alarm, easy and simple to handle, flexible, and action is coherent, steady, and safe in operation, reliable makes folded formula draw gear 120 can realize automatic deploying and retracting, the function of efficiently drawing the fault vehicle.
With traditional truck trailer, compare, this wrecker 100 utilizes its turn radius little, the advantages such as scantling of structure is little, on crowded urban highway, can show powerful alerting ability and crossing ability on narrow street, thereby be conducive to arrive rescue site in the very first time, be drawn, haul operation.And it is little that it also has energy consumption, the little environment-friendly advantage that waits of quantity discharged.In addition, in working process, also can utilize the onboard wireless remote controller to control at safety zone, greatly improve safety.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and not be used as limitation of the invention, as long as in connotation scope of the present invention, to variation, the modification of the above embodiment, all will drop in claims scope of the present invention.
