The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Please in conjunction with Fig. 1, shown in Figure 2, miniature road traction wrecker 100 of the present utility model 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 four wheel drive motor dillies such as (ATV), it is little that such vehicle has a volume, horsepower foot, advantages such as towability is strong, turn radius is little, good operation performance have better flexibility and crossing ability on crowded urban highway and narrow street.Collapsible draw gear 120 comprises containing box 130, fold mechanism 140, lifting mechanism 150, embraces wheel mechanism 160 and traction wheel 170, and containing box 130 is located at power car 110 afterbodys upper end, is used to take in the draw gear 120 after folding; Fold mechanism 140 1 ends and power car 110 are hinged, and a lifting mechanism 150 and an armful wheel mechanism 160 all are located at fold mechanism 140 other ends, and traction wheel 170 links to each other 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, folding hydraulic actuating cylinder 146 and electronic reel (not shown), and longeron 141 1 ends and power car 110 afterbody after-frames are hinged; Preceding tie-beam 142 is hinged with longeron 141, and back tie-beam 143 and preceding tie-beam 142 are hinged; Left and right crossbeam 144,145 is located at the both sides of back tie-beam 143, and is hinged with back tie-beam 143 by folding connecting rod 147 is set respectively; Folding hydraulic actuating cylinder 146 is located on the tie-beam 143 of back, and is hinged with folding connecting rod 147, is used to drive folding connecting rod 147 rotations, folds or launches thereby can drive left and right crossbeam 144,145; Electronic reel is located on the power car 110, and is connected with longeron 141 by hauling rope, packing up or putting down in order to control longeron 141.Lifting mechanism 150 comprises lifting support 151 and lifting hydraulic cylinder 152, and lifting support 151 is hinged respectively is located at left and right crossbeam 144,145 two side ends; Lifting hydraulic cylinder 152 is hinged respectively to be located on the lifting support 151, in order to drive 151 rotations of lifting support.Embrace wheel mechanism 160 and comprise armful wheel arm 161 and embrace a wheel hydraulic actuating cylinder 162 that an armful wheel arm 161 is located between the lifting mechanism 150, and is located at respectively on the left and right crossbeam 144,145; Embrace wheel hydraulic actuating cylinder 162 and be located at respectively on the left and right crossbeam 144,145, and an end embraces 161 rotations of a wheel arm with corresponding to embrace wheel arm 161 hinged in order to drive, embrace a wheel arm 161 and embrace the fault vehicle front-wheel respectively thereby can make.Traction wheel 170 is located at respectively on the turning rack 171, and forms an eccentric throw with the center of gyration of turning rack 171, realizes follow-up steerings so that follow power car 110.Turning rack 171 is connected and fixed with lifting support 151, and can be with 151 upsets of lifting support; Also be provided with synchronous braking device 172 on the traction wheel 170, can carry out synchronous braking with small-sized traction power car 110.This wrecker 100 also comprises car-mounted computer control system (not shown), is electrically connected with electronic reel and each hydraulic actuating cylinder respectively, in order to the startup and the stroke of accurate Calculation and the electronic reel of automatic guidance and each hydraulic actuating cylinder.This wrecker 100 also comprises the Digiplex (not shown), can in order to carry out wireless controlling in safety zone, improve safety to car-mounted computer control system emission wireless control signal.
The principle of work of the collapsible draw gear 120 of this wrecker 100 is as follows:
Before using, draw gear 120 is in folding full reduced state, places in the containing box 130 of traction power car 110 after-frames top.During use, utilize the deadweight (the deviation of gravity center strong point) of draw gear 120 earlier, manipulation onboard wireless remote controller discharges hauling rope slowly by electronic reel, longeron 141 is lowered into vertical surface be about 30 ° of angles (not being advisable not interfere with traction power car 110 after-frames); The folding hydraulic actuating cylinder 146 of control shrinks then, drives folding connecting rod 147 motions, and then causes the Unscrew of left and right crossbeam 144,145 and lifting support 151, thereby realizes the expansion action of draw gear 120; Continue to discharge lentamente the rope of electronic reel again, deadweight and traction wheel 170 and ground-surface rolling by draw gear 120 launch left and right crossbeam 144,145 and lifting support 151 fully, and horizontal on the ground; Drive traction power car 110 reversing this moment, will embrace wheel arm 161 and shift fault vehicle front-wheel position onto, and control is embraced a wheel hydraulic actuating cylinder 162 and driven and embrace a wheel arm 161 and block corresponding front-wheel respectively; And then control lifting hydraulic cylinder 152 and stretch out, make lifting support 151 clickwises, and then left and right crossbeam 144,145 and whole armful of wheel mechanism 160 are lifted thereupon, thereby the fault vehicle front-wheel is lifted, can draw, haul operation.
Adopt small-sized traction power cars 110 such as ATV, advantages such as both having kept its powerful, be fit to multiple landform, towability is strong, operating characteristic is excellent, crossing ability is good can satisfy the arrangement space needs of collapsible draw gear 120 and hydraulic power system thereof again.By calculation control, under the drive of folding hydraulic actuating cylinder 146, can accurately realize the auto-folder and the expansion action of similar " the folded umbrella formula " of whole folded formula draw gear 120.Drive and embrace wheel arm 161 and realize holding tightly automatically by the wheel hydraulic actuating cylinder 162 of embracing that is arranged on the left and right crossbeam 144,145 the fault vehicle front-wheel of being hauled.And the hinge of lifting mechanism 150 and lifting support 151 is optimized reasonable Arrangement through numeral, is keeping can improving hoisting force to greatest extent under the less prerequisite of lifting mechanism 150 sizes.Lifting hydraulic cylinder 152 is hidden in lifting mechanism 150 inside, compactness not only simple for structure, and also its hydraulic cylinder piston rod can exempt from and damage or pollute, 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, realizes follow-up steering so that follow power car 110.Can realize folding, launch, embrace actions such as wheel, lifting by full automaticity by the car-mounted computer control system.The whole control system can also have multiple functions such as operation locking, fault alarm, and is easy and simple to handle, flexible, and action links up, steadily, and safe in operation, reliable makes folded formula draw gear 120 can realize automatic deploying and retracting, efficiently draw the function of fault vehicle.
Compare with traditional truck trailer, this wrecker 100 utilizes its turn radius little, advantages such as scantling of structure is little, on crowded urban highway, can show powerful alerting ability and crossing ability on the narrow street, draw, haul operation thereby help arriving rescue site in the very first time.And it is little that it also has energy consumption, the little environment-friendly advantage that waits of quantity discharged.In addition, in the working process, also can utilize the onboard wireless remote controller to control, improve safety greatly at safety zone.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
