Step 101, hollow cross is set in to the front end of being rescued vehicle, and by circular hole bolt through the described towing pad of being rescued the front end of vehicle, then be fixed by nut;
Step 102, one end of lifting chain is fixed on to unloading on the arm head of the vehicle-mounted crane on breakdown lorry buckles, and regulate described lifting chain, the other end of described lifting chain is connected with clamp by having strong market potential with the draw bar connecting portion of described hollow cross;
Step 103, by described vehicle-mounted crane, the described vehicle of being rescued is risen and winches to the first preset height, tire support is placed on respectively to the described tire below, propons left and right of being rescued vehicle;
Step 104, by the tight device of bolt, by the described propons left and right sides of being rescued vehicle and chassis side rail, bolt is tight respectively, makes the described propons of being rescued vehicle and described chassis side rail without relative motion;
Step 105, by described vehicle to the second preset height of being rescued of described vehicle-mounted crane lifting, one end of described draw bar is connected to described breakdown lorry, the other end is connected with clamp by having strong market potential with the draw bar connecting portion of described hollow cross;
Step 106, by described vehicle-mounted crane, regulate sling height, and remove described tire support.
In above-mentioned installation procedure, relate to the operation of adjusting sling height for three times, the effect of wherein adjusting for the first time sling height is the ground clearance that makes tire, can place tire support, to be placed on tire support by breakdown lorry front axle tyre, facilitate rescue group under car, to bundle leaf spring and propons; Effect is to facilitate draw bar and be connected by breakdown lorry for the second time; Effect is for the third time that the ground clearance of tire is increased, and can remove tire support, can also regulate by the breakdown lorry ground Clearance, adapts to road conditions.
By above, to hanging the explanation of structure and the installation process of leading deliverance apparatus, be appreciated that of the present utility model hanging lead deliverance apparatus and have following at least one advantage than prior art:
1, draw bar comprises multistage connection structure in relative rotation, and moment of flexure is less, can occur on road surface when uneven avoiding because the torsion between vehicle causes the destruction to draw bar, and safety is higher;
2, the lifting chain that is arranged on vehicle-mounted crane and is rescued vehicle front can be adjusted length and regulate and rescued vehicle sling height, reduces the requirement of road pavement, improves road surface carrying capacity;
3, the use by the tight device of bolt is bundled in vehicle bridge on chassis side rail, makes both relative motion can not occur, and reduces because leaf spring or elastic element change the problem of bringing, and reduces tire liftoff height;
4, can form the multiple combination frock corresponding to different automobile types according to vehicle size Selection assembly parts, ensure that vehicle is many;
5, existing drag type tow lift is when breakdown lorry, lift mechanism need to be rescued vehicle bottom by lifting long being deep into of bar, then tire is lifted to rising, while causing rescue, car load is larger by circle diameter, and by comparison, of the present invention hanging led deliverance apparatus because draw bar is all adjustable with lifting chain, shortened tow lift and by tow lift relative distance, during rescue car load to pass through circular diameter less, so turn radius is little, maneuvering performance is good;
6, each assembly parts can be dismantled after finishing using, easy to use, takes up room little.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
