The invention discloses a double-connected double-drum rope winding system, which includes two sets of driving drums, a fixed pulley block, a movable pulley block, a balance device and a main beam of a vehicle frame. The fixed pulleys are arranged in a straight line on the main beam of the frame, and two sets of driving drums are symmetrically arranged on both sides of the main beam, driven by the motor and the reducer; the steel wire rope is fixed at both ends of the driving drum and wound from both ends to the middle. The lifting mechanism adopts two sets of driving devices, and the two sets of reels are connected by a balancing device. The invention provides a mixed interlaced rope winding system based on double-connected double drums, which ensures the safety of the mechanism, has good synchronization, simple layout, good manufacturing process, and produces a variety of lifting weights through modular design. Different products meet the requirements of users for multiple loads, multiple working conditions, and multiple varieties, shorten the design cycle, reduce production costs, and improve production efficiency.
Description
technical field [0001] The invention relates to a rope winding system of a crane, in particular to a rope winding method and an arrangement form of a hoisting mechanism when the lifting capacity is large, and belongs to the technical field of hoisting machinery. Background technique [0002] At present, when the crane has a large lifting capacity, its hoisting mechanism usually uses two or more sets of driving and winding mechanisms, and the drums of the two driving devices are rigidly connected. The hook is skewed, which affects the safety of lifting and hoisting. In addition, the arrangement of various mechanisms is asymmetrical, resulting in unbalanced pressure on the trolley wheels, unstable operation, affecting normal use, and serious accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mixed interlaced rope winding system based on double-connected double drums, aiming at the defects and deficiencies...
