Abstract

The invention discloses a cable take-up and pay-off control method, device and system for hoisting equipment. Swing data of a cable swing rod of the hoisting equipment is obtained, the swing data comprises a swing angle and / or torque, wherein the swing angle represents an included angle between the cable swing rod and the vertical direction when the cable swing rod swings, the torque represents a torque value for driving the cable swing rod to swing, the cable winding and unwinding speed of a reel of the hoisting equipment is adjusted according to a comparison result between the swing angle and a preset swing angle threshold value, and / or according to a comparison result between the torque and a preset torque threshold value, the cable winding and unwinding speed of the reel of the hoisting equipment is adjusted, and the cable is arranged in the reel. The cable winding and unwinding speed of the reel of the hoisting equipment is adjusted according to the comparison result between the swing angle of the cable swing rod of the hoisting equipment and the preset swing angle threshold value, and / or the cable winding and unwinding speed of the reel of the hoisting equipment is adjusted according to the comparison result between the torque and the preset torque threshold value, so that protection of the cable is improved, and the cable is prevented from being damaged.

Description

technical field [0001] The present application relates to the technical field of cable retraction control, and in particular to a cable retraction control method, device and system for lifting equipment. Background technique [0002] At present, it is more common to need crane construction in engineering operations, and the weight of cranes for engineering applications is gradually increasing. At the same time, the required performance and functional requirements are also gradually increasing. Consider the safety performance of the crane. For example, during the construction process, the cable reel in the crane may be required for operation. During the operation process, if the cable is retracted too quickly, the cable is easy to be damaged. If the cable is not retracted in time, the cable is too long and it is easy to step on the cable. Therefore, it is impossible to detect the tightness of the cable during the actual operation, which will reduce the work efficiency and ea...
