Abstract:

In order to promote the progress and quality improvement of the remanufacturing technology of coal mine anchor excavator, the current status of the remanufacturing of anchor excavator and the drafting of technical specifications and standards were analyzed; Studied the repair of cracks in structural components, repair of wear-resistant plates, repair of cutting drums, remanufacturing of sliding frames, remanufacturing of reducers, remanufacturing of electric control box boxes, and other key technological iterations; Elaborate on the remanufacturing process flow, testing and testing of key components and systems, and quality control system. We have completed the remanufacturing of 14 anchor excavators, including 12 imported anchor excavators and 2 domestically produced anchor excavators, with good performance. Aiming at the problems of weak theoretical foundation, imprecise process, and lack of advanced technology in remanufacturing, innovative ideas are proposed, namely: treating remanufacturing of excavator anchor integrated machine as a new product development, strengthening the application of remanufacturability evaluation and service life prediction methods, strengthening remanufacturing design, applying remanufacturing experience to excavator anchor integrated machine design, highlighting the value of information construction and expanding digital applications, and innovating remanufacturing service concepts.
