Abstract

Embodiments of the present invention provide a method, a device and a crane for controlling the threading of a crane hook, which relate to the field of hoisting equipment. The control method for threading a crane hook includes the following steps: controlling a luffing hoist to drive a main arm to lift a first preset Set the height; control the main hoist to release the rope, the auxiliary hoist to rewind the rope, and the main hoist's rope release speed is less than or equal to the auxiliary hoist's rope take-up speed to tension the rope; when the auxiliary hoist's rope retraction pressure is greater than or equal to the preset pressure , the auxiliary winch is controlled to stop taking up the rope, and the luffing winch is controlled to drive the main arm down to a second preset height to loosen the rope, wherein the second preset height is less than or equal to the first preset height. The method for controlling the rope threading of a crane hook, the corresponding control device and the crane can effectively improve the phenomenon that the rope of the main hoist is disordered and the rope of the auxiliary hoist is trapped during the rope threading operation of the crane hook.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a method and device for controlling the rope threading of a crane hook and a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. The hook of the crane needs to be threaded during installation. Generally, the main hoist is used to release the rope, and the auxiliary hoist is used to take in the rope. The entire rope threading operation is completed manually. [0003] However, when the existing cranes are threading, either the main hoist is prone to rope disorder, or the auxiliary hoist is prone to rope trapping. Contents of the invention [0004] The object of the present invention includes, for example, to provide a crane hook rope threading control method, device and crane, which can effectively improve the phenomenon of main hoist rope disorder and auxilia...
