Bidirectional anti-slipping apparatus in monorail crane based on inner ratchet mechanism

A bidirectional anti-slipping apparatus in a monorail crane based on an inner ratchet mechanism, comprising a vehicle following stabilizing mechanism, a track, and two front and rear sets of locking mechanisms with opposite rotation directions, wherein 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, and a front vehicle and a rear vehicle are respectively fixed at two front and rear ends of the protective shell through connecting rods;

• each locking mechanism includes two left and right groups of ratchet devices adapted to the track, each of the ratchet devices includes a fixing rod, a plurality of driving plates are respectively fixed at two ends of the fixing rod on a side of the fixing rod proximate to the track, a plurality of ejectable ratchet pawls are arranged along a circumferential direction of each of the driving plates, a rotatable inner ratchet wheel is further arranged along the circumferential direction of each of the driving plates, a plurality of locking grooves adapted to the ratchet pawls are arranged in an inner wall of the inner ratchet wheel attached to the driving plate, the ratchet pawls are capable of limiting the inner ratchet wheel to rotate unidirectionally in cooperation with the locking grooves and inner ratchet wheels on the two front and rear sets of locking mechanisms rotate in opposite directions;
• and
• a front locking mechanism is arranged between the front vehicle and the middle vehicle, 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, a rear locking mechanism is arranged between the rear vehicle and the middle vehicle, 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.
