Further improvement to above-mentioned technical proposal is: the Electric rope winder includes bottom plate and is located at bottom plate two sides Support is rotatably connected to tubular long rack wheel between two supports, there are two transmission gear both sides are set side by side Cord winder, cord winder include the screw rod being fixed between two supports, are equipped with by thread bush on screw rod and to be moved along screw rod Bull wheel, the both ends of bull wheel are fixed with the driven gear engaged with transmission gear, reversely lead to steel wire on two bull wheels Rope, wirerope are connected on the hydraulic cylinder outer wall by the pulley assembly that reversed outbound course is arranged, pulley assembly peace On bottom plate, Electric rope winder is fixed on through beam by its bottom plate, the transmission gear by motor driven drive from The tightening of moving gear control wirerope is loosened, and motor is mounted on the outside of through beam.

Further improvement to above-mentioned technical proposal is: the through beam is the bathtub construction that Open Side Down, oil cylinder branch The bottom of bathtub construction is arranged in frame, and Electric rope winder is fixed on the bottom of bathtub construction by its bottom plate, and hydraulic cylinder passes through Wirerope is retracted in the bathtub construction of through beam.

Further improvement to above-mentioned technical proposal is: the perforation beam width and box width are adapted, through beam It is fixed by being located at the L shape perforation boom support on the outside of stringer, the through beam between two perforation boom supports and stringer bottom Between be welded with perforation girder bearing plate.

The utility model has the advantages that compared with prior art, the utility model includes

1. hydraulic cylinder piston passes through ground supports plate and ground face contact after stretching out, increase the contact point of vehicle and ground, Width is adapted with box width and avoids interference with simultaneously, can effectively prevent loading space lifting rollover；

2. higher than the intensity of support frame using hydraulic cylinder support degree；

3. hydraulic cylinder is lifted in income through beam by Electric rope winder by the way that through beam is arranged in bottom of frame Portion does not influence the passage capacity of vehicle traveling；

4. increase hydraulic cylinder on through beam and ropewinder arrangement is simple, it is equal relative to existing most self-dumping undercarriage for automobile It can arrange, it can be achieved that with universal performance height；

5. through beam makes sound construction by L bracket fixation, the purpose that backing plate is arranged is avoided under through beam and vehicle frame The end face gap Jian You, prevents because there is the local deformation occurred after the stress of gap.
