Embodiment 1

[0035] figure 1 The flowchart of the steel wire rope job-hopping detection method provided by the embodiment of the present invention, such as figure 1 As shown, the steel wire rope slot detection method provided by the embodiment of the present invention includes:

[0036] Step S101, obtaining real-time offset information of the wire rope relative to the rope groove 11 on the drum 1;

[0037] Step S102, analyzing and obtaining the position information of the steel wire rope relative to the rope groove 11 on the reel 1 according to the obtained real-time offset information; when the obtained position information exceeds the set threshold, a control command is generated to control the reel operating mechanism to make Prevent the wire rope from jumping.

[0038] Using the method provided by the present invention to detect the offset of the wire rope, at first, in step S101, obtain the real-time offset information of the wire rope relative to the rope groove 11 on the reel 1, t...

Abstract

The invention provides a detecting method for disengagement of a steel wire rope from a groove and a detecting device and relates to the technical field of lifting devices. The detecting method for disengagement of the steel wire rope from the groove comprises the steps that real-time deviation amount information of the steel wire rope relative to a rope groove on a winding drum is obtained; according to the obtained real-time deviation amount information of the steel wire rope, the position information of the steel wire rope relative to the winding drum is analyzed and obtained; and when the obtained position information exceeds a set threshold value, a control instruction is generated, and the control instruction is used for controlling a winding drum operation mechanism to conduct action to prevent the steel wire rope from disengaging from the groove. When the detecting method is used for detecting disengagement of the steel wire rope from the groove, the technical problem that in the prior art, the steel wire rope disengages from the groove can be solved, and disengagement of the steel wire rope from the groove can be effectively predicted.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a detection method and detection device for steel wire rope skipping. Background technique [0002] The drum is an important part of the lifting equipment. The wire rope is wound in the rope groove on the drum. When in use, the drum is driven to rotate downward to release the wire rope or rotate in the opposite direction to wind up and tighten the wire rope to realize the falling and rising of the material. [0003] When actually operating the lifting equipment to lift the material up or down, due to the structural characteristics of the lifting equipment, the operator in the operating room cannot observe the state of the wire rope on the reel, nor can he observe the gap between the hook on the wire rope and the material to be hoisted. When the hook has touched the material to be hoisted, if the operator continues to release the wire rope downward, the wire rope in the...
