Problems solved by technology

[0004] However, due to the phenomenon such as slippage between the steel wire rope 6 wound by the hoist 1 and each pulley, the reel speed of each hoist 1 is inconsistent with the speed of the wire rope end of each hoist 1 lifting heavy objects. There is a large error in the synchronous control of the hoist

Abstract

The invention provides a multi-winch synchronization control method and control system. The control system comprises a control device and a plurality of pull force sensors. Each pull force sensor is hinged to one arm head pulley of a multi-winch synchronization mechanism. The control device connected with the pull force sensors acquires a current lifting pull force value, obtained by the pull force sensors, at a steep wire rope end, and performs deviation calculation on the current pull force value and the previous pull force value to obtain a pull force difference value; under the circumstance that the absolute value of the current pull force value is larger than the preset pull force difference value pre-stored by the control device, when the pull force different value is larger than zero, the control device controls winding drums of the winches to slow down, and when the pull force difference value is smaller than zero, the control device controls the winding drums of the winches to accelerate. Due to the fact that the steel wire rope end is close to a hanging hook, balance lifting control of the hanging hook can be accurate by the control method collecting pull force value of the steel wire rope end, and multi-winch synchronization control precision can be increased effectively.

Description

technical field [0001] The invention relates to the technical field of multi-hoist synchronous control, and more specifically, relates to a multi-hoist synchronous control method and control system. Background technique [0002] With the advancement of technology, lifting equipment is gradually developing towards large-tonnage and super-large-tonnage. In order to meet the needs of development, large-tonnage and super-large-tonnage hoisting Multiple sets of hoisting systems work synchronously to lift and place the same heavy object, thereby improving the accuracy and lifting capacity of the hoisting equipment. [0003] Synchronous control of multiple hoists is the key technology for synchronous lifting of lifting equipment. In order to ensure that the wire ropes of multiple hoists move synchronously during the movement of the hook, the method of detecting the drum speed of each hoist is usually used to control the synchronous movement of the wire ropes. . figure 1 It is a s...
