Preferably, every including at least three in the anticollision subassembly anticollision piece, anticollision piece evenly lays on rubber spring's the side, so sets up, through the setting of a plurality of anticollision pieces, has prolonged anticollision subassembly's life, when one of them or two anticollision pieces go wrong, does not influence holistic buffering anticollision effect.
Preferably, the anticollision subassembly still includes soft rope, soft rope winding is in annular recess on the rubber spring, so set up, further improved the crashproof ability of buffering of anticollision subassembly.
The utility model has the advantages that:
(1) the utility model improves the anti-collision buffering capacity of the crane trolley through the arrangement of the rubber spring and the anti-collision block in the anti-collision component, and simultaneously, the cooperation of the air bag and the soft rubber block can play a better effect of absorbing the kinetic energy of the crane trolley;
(2) through the arrangement of the arc-shaped buffer slope, the walking track can absorb part of the kinetic energy of the crane trolley, and the anti-collision buffer capacity of the anti-collision assembly is matched, so that the anti-collision buffer capacity of the whole anti-collision structure is improved;
(3) the anti-collision structure is simple in overall structure, the service life is prolonged through the arrangement of the anti-collision blocks, the use cost is low, and the anti-collision structure has a good market prospect.
