Abstract

The embodiment of the invention provides a method and device for controlling passing through of a rope in a crane hook and a crane, and relates to the field of crane equipment. The method for controlling passing through of a rope in a crane hook comprises the following steps of controlling a luffing winch to drive a main arm to raise by a first pre-set height; controlling a main winch to release the rope and an auxiliary winch to retract the rope to tension the rope, wherein the rope releasing speed of the main winch is smaller than or equal to the rope retracting speed of the auxiliary winch;and when the rope retracting pressure of the auxiliary winch is greater than or equal to the pre-set pressure, controlling the auxiliary winch to stop retracting the rope, and controlling the luffingwinch to drive the main arm to fall down by a second pre-set height to loosen the rope, wherein the second pre-set height is smaller than or equal to the first pre-set height. Through the adoption ofthe method and device for controlling passing through of a rope in a crane hook and the crane disclosed by the invention, the phenomena that during the operation of passing through of the rope in thecrane hook, the rope in the main winch is disordered, and the rope of the auxiliary winch is trapped can be effectively improved.

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...
