Embodiment Construction
[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] The embodiment of the present invention provides a hoist synchronous control device for multi-hoist single-hook lifting equipment. The hoist synchronous control device for multi-hoist single-hook hoisting equipment can The work needs to configure its magnification separately, and the magnification of multiple winches can be set to be the same or different. The winch synchronous control device of this embodiment realizes the synchronous setting of winches with different magnifications.

The invention provides a winch synchronization control method and device of a multiple-winch single-hook type hoisting device. The winch synchronization control method comprises the steps of respectively obtaining the rotating speed of winding drums of multiple winches, utilizing the rotating speed to calculate the lifting speed of the multiple winches according to the steel wire rope multiplying power of the multiple winches and respectively sending rotating speed control signals corresponding to the winches according to the lifting speed so as to ensure consistency of the lifting speed of the multiple winches. The winch synchronization control method and device calculates and obtains the lifting speed of the winches by utilizing the speed of the winding drums of the winches and the steel wire rope multiplying power corresponding to the winches, uses the lifting speed as a feedback value, sends speed adjusting signals to the winches in real time so as to ensure the consistency of the lifting speed of the winches and accordingly enables hooks lifted by the winches jointly to be balanced. When the multiplying power of one winch is not consistent with other winches, the winch synchronization control method and device can ensure the balance of the lifted hooks.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a hoist synchronous control method and control device for multi-hoist single-hook type hoisting equipment. Background technique [0002] Multi-winch single-hook lifting equipment controls the lifting of a single hook through multiple winches, and is usually a large-tonnage lifting equipment. figure 1 It is a schematic diagram of the existing multi-winch single-hook lifting equipment. When lifting a heavy load, multiple winches are used to bypass the pulley blocks 13 through their respective wire ropes 12, and simultaneously lift a lifting hook 11. [0003] The structure of multi-winch and single hook is suitable for large lifting weight and improves the lifting effect of the hook. In the above multi-hoist single hook structure, it is necessary to ensure that the wire ropes of multiple hoists cooperate in the movement of the hook. In the existing hoist synchronous control sy...
