The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
By Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the hoisting crane supporting leg of the utility model embodiment is handled device in the same way, comprise the right mounting bracket 10 and the left installation bracket 8 that are fixed on the vehicle frame 9, by hinge 1 and six right bar handles 13 of right mounting bracket 10 bonded assemblys, the right flexible axle support 11 that is connected with right mounting bracket 10, by hinge 3 and six left bar handles 2 of left installation bracket 8 bonded assemblys, the left flexible axle support 6 that is connected with left installation bracket 8, be loaded on the multiple directional control valve 12 on the right mounting bracket 10, six roots of sensation flexible axle 5 is loaded on left flexible axle support 6, on the right flexible axle support 11, and the two ends of every flexible axle 5 link to each other with left bar handle 2 with the inner of a spool 16 of multiple directional control valve 12 respectively, the outer end of this spool 16 links to each other with right bar handle 13 by bearing pin 15, wherein the connecting portion (bearing pin 4) of every flexible axle 5 and left bar handle 2, and the outer end of spool 16 that this flexible axle 5 connects and the connecting portion of right bar handle 13 (bearing pin 15) are arranged in a crossed manner in the hinge 3 of bar handle and 1 below and top separately;
