Rear landing leg fine-tuning mechanism for kerbstone slip-form paver

The invention discloses a rear landing leg fine-tuning mechanism for a kerbstone slip-form paver. The rear landing leg fine-tuning mechanism comprises a drive caterpillar band, a fixed mount, a lifting inner barrel, a lifting outer barrel and a hinged bracket, and further comprises a bracket fixed to the lifting outer barrel, wherein the fixed mount is connected above the drive caterpillar band; the lifting inner barrel is fixed to the fixed mount; the lifting outer barrel is connected at the outer side of the lifting inner barrel in a sleeving mode; a steering sleeve which can rotate around the lifting outer barrel is arranged at the outer side of the lifting outer barrel below the bracket in the sleeving mode; an upper connecting frame of the hinged bracket is fixed to the two sides of the steering sleeve; the lower connecting frame of the hinged bracket is fixed to the two sides of the fixed mount; the two sides of the bracket are connected with regulating bolts; top ends of the regulating bolts abut against a fixed block of the upper connecting frame. According to the rear landing leg fine-tuning mechanism, a fine-tuning mechanism is additionally arranged, so that on one hand, influence on the integral structure is relatively small and the structure is simple, on the other hand, whole-machine travelling imbalance caused by processing or assembly errors can be overcome, and therefore, the whole machine can be stably operated, and the service life of the equipment is prolonged.
