WIPO Patent Application WO/2023/142631

A1

A straightening method for a multi-node device, used for automatically straightening a hydraulic support array and/or automatically straightening a scraper in a fully mechanized coal mining face system. The method comprises: a control device determines a first adjustment amount by means of position information and attitude angle information of hydraulic supports and a first target value of each hydraulic support in a hydraulic support array in a straightening direction, so that each hydraulic support adjusts the hydraulic support array according to the first adjustment amount, and/or the control device determines a second adjustment amount by means of the position information and attitude angle information of the hydraulic supports, the value of the length of extension of a push rod of each hydraulic support, and a second target value of a target node on the scraper connected to each push rod, so that each hydraulic support can perform a push operation on the scraper by means of the push rod so as to straighten the scraper. According to the method, the attitude angle information of the supports is fully considered during straightening of the support array and/or the scraper, thereby improving the straightening accuracy of the support array and/or the scraper.
