Method and apparatus for controlling a reel of a stacker-reclaimer to perform a cable winding operation

Abstract

The invention provides a method and a device for controlling cable coiling operation of a reel of a piling and taking machine, and belongs to the field of port machinery. The method comprises the following steps of detecting whether a cable over-loose limit switch is triggered or not, and controlling the reel to execute the cable coiling operation under the condition that the cable over-loose limit switch is triggered. The device comprises the cable over-loose limit switch for indicating whether the cable of the piling and taking machine is too loose or not, a relay for controlling the reel toexecute the cable coiling operation, and a controller for detecting whether the cable over-loose limit switch is triggered or not and outputting a signal to the relay so as to enable the relay to control the reel to execute the cable coiling operation under the condition that the cable over-loose limit switch is triggered. According to the method and the device for controlling the cable coiling operation of the reel of the piling and taking machine, under the condition that the cable is too loose, the reel is controlled to automatically execute the cable coiling operation, and so that the cable can be automatically coiled when the cable is too loose; and moreover, the time for processing a cable over-loose fault is shortened, the safety and the reliability of processing the cable over-loose fault are improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of port machinery, in particular to a method and device for controlling a reel of a stacker-reclaimer to perform a cable winding operation. Background technique [0002] The power cable and control cable of the stacker-reclaimer play a vital role in the operation of the single machine, and the fault of the cable reel is also a relatively important fault, which affects the walking of the single machine. When the stand-alone machine is walking or working, due to problems such as the torque of the cable reel reducer and the travel brake, the power cable and the control cable are often too loose, and the stand-alone machine cannot walk. Troubleshooting this fault requires the operator to manually coil the cables, wasting time. Affecting the timeliness of operation, especially in the current remote operation of the reclaimer, maintenance personnel need to go to a single machine to deal with it, which further increases the...
