Problems solved by technology

The quality of the lifting mechanism will directly affect the working performance of the whole crane. The lifting mechanism is mainly composed of a driving device, a transmission device, a reel, a pulley block, a pick-up device and a braking device. In addition, various Auxiliary devices, such as lifting height limiter, moment limiter, three-turn protection and other safety devices, the braking and deceleration devices of the existing cranes are integrated in the reducer, and the motor and drum are realized through gear transmission deceleration. Due to the complexity of the force of the lifting mechanism during the lifting of the cargo, the emergency braking will cause great damage to the motor. At the same time, due to the inertia of the motor rotation, the motor and the reel do not have the conditions for simultaneous braking. The braking device installed inside the lifting device cannot achieve the ideal braking effect

Abstract

The invention discloses a hoisting mechanism of a hook bridge crane. The hoisting mechanism of the hook bridge crane comprises a winch, a motor and a reducer; the transmission shaft of the motor and the shaft of the winch extend out of the left end of the reducer and provided with a shaft brake spoke and a rolling brake spoke respectively; the shaft brake spoke and the rolling brake spoke are provided with a differential dual-brake mechanism, the differential dual-brake mechanism comprises a base, both ends of the top surface of the base are provided with first supports and second supports, wherein the second supports are arranged inside the first supports; a hydraulic cylinder is mounted between the two second supports, two connecting rods are hinged at the top of the hydraulic cylinder through an extending rod. By means of the differential dual-brake mechanism, the motor can maintain a stable stopping state during hoisting and avoid swinging of steel cables caused by braking force; meanwhile, by means of duel-brake measures, braking stability can be ensured, and the hoisting mechanism of the hook bridge crane is more applicable to hoisting stabilization of heavy objects.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a hoisting mechanism of a hook bridge crane. Background technique [0002] The lifting mechanism is a must-have for any crane, and it is the basic component that enables objects to be lifted and lowered. The quality of the lifting mechanism will directly affect the working performance of the whole crane. The lifting mechanism is mainly composed of a driving device, a transmission device, a reel, a pulley block, a pick-up device and a braking device. In addition, various Auxiliary devices, such as lifting height limiter, torque limiter, three-turn protection and other safety devices, the braking and deceleration devices of the existing cranes are integrated in the reducer, and the motor and drum are realized through gear transmission deceleration. Due to the complexity of the force of the lifting mechanism during the lifting of the cargo, the emergency braking will cause great dam...
