Hoisting wire pulley device for crane

Abstract

The invention discloses a hoisting wire pulley device for a crane. The device comprises a shell, a connecting plate is welded to the lower end of the shell, a base plate is connected to the lower endof the connecting plate through spring assemblies, a hook lock is fixed to the lower end of the base plate, three shaft rods are sequentially arranged in the shell, pulley bodies are connected to theouter parts of the three shaft rods in a rotating mode, grooves are formed in the outer surfaces of the pulley bodies, meanwhile, each spring assembly comprises spring bodies and two spring seats, andthe two spring seats are fixed to the two ends of the corresponding spring bodies. The device has the advantage that the shell, screw caps, the connecting plate, the spring assemblies, the base plate, a damping pad, the pulley bodies, the shaft rods, nuts, the spring bodies, the spring seats and protective covers are arranged, so that the problems that the safety of a hoisting wire pulley devicefor a crane at the present stage is low in the using process, and goods are prone to shake due to the fact that a pressure buffering device is not arranged can be solved.

Description

technical field [0001] The invention relates to the technical field of crane equipment, in particular to a crane suspension wire pulley device. Background technique [0002] At present, a crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as crane, aerial crane, crane. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Very broad market space. Among them, the crane needs to use the wire pulley device when it is in use. The wire pulley plays a very important role in the lifting and handling of the goods, which can make the movement of the goods more stable, so it is suitable for the use of crane equipment. The current crane wire pulley The de...
