Inner ratchet mechanism-based bidirectional anti-slip device for monorail crane

TEXT OF THE The present disclosure provides a bidirectional anti-slipping apparatus in a monorail crane based on an inner ratchet mechanism. The apparatus includes a vehicle following stabilizing mechanism, a track, and two front and rear sets of locking mechanisms with opposite directions. The vehicle following stabilizing mechanism includes a protective shell, a middle vehicle capable of sliding and a hydraulic cylinder configured to control the middle vehicle to slide are arranged in the protective shell, a front vehicle and a rear vehicle are respectively fixed at two front and rear ends of the protective shell. Each locking mechanism includes two left and right groups of ratchet devices, each of the ratchet devices includes a fixing rod, a plurality of inner ratchet wheels capable of rotating unidirectionally are respectively fixed at two ends of the fixing rod on one side of the fixing rod proximate to the track, the inner ratchet wheels on the two front and rear sets of locking mechanisms rotate in opposite directions. Two ends of the fixing rod on the front locking mechanism are respectively hinged with the front vehicle and the middle vehicle through front rocker arms, and two ends of the fixing rod on the rear locking mechanism are respectively hinged with the rear vehicle and the middle vehicle through rear rocker arms. The apparatus can achieve the function of bidirectional anti-slipping in the monorail crane, prevent the accidents of vehicle slipping in the monorail crane, ensure the safety of operators and realize the safe transportation.
