Reason analyses and treatments of the derailing problem of main harrow tensioning wheel and the unsoldering problem of oil cylinder base of a reclaimer

Abstract

Abstract:

A reclaimer in strip material yard is a type of environmentally friendly large mechanical equipment and the tensioning condition of chains would directly influence its normal operation. According to the calculation formulas of pretightening force and minimum pretightening force, the type selection of tension cylinder could be conducted, including the appropriate cylinder diameter and cylinder pressure. Through analyzing, this paper considered that the main reason of the derailing problem of main harrow tensioning wheel and the unsoldering problem of oil cylinder base is misoperation. After that, this paper provided corresponding solutions for the above problems.

Key words:

reclaimer, chain wheel tensioning, chain, pretightening force, cylinder base, unsoldering
