1.改装原因在高填土方工程中,为了使回填土达到一定密实度,经常需要用到凸块轮压路机。由于我单位光轮压路机较多,从经济、快捷和实用等方面考虑,我们决定自行将光轮压路机改装为凸块轮压路机。本文阐述光轮压路机改装为凸块轮压路机的方法。2.改装方法光轮压路机改装为凸块轮压路机,主要方法是将铸铁凸块按一定排列顺序焊接在光轮压路机钢轮上,具体方法如下所述。(1)选择焊机及焊条为了便于焊接、降低焊接成本、缩短焊接 1. Reasons for modification In the high-fill project, in order to make the backfill soil to achieve a certain degree of density, often need to use the bump wheel roller. Because of my unit light wheel roller more, from the economic, efficient and practical considerations, we decided to convert the light wheel roller into a bump wheel roller. This article describes the method of retrofitting a light roller to a bump roller. 2. Modification Method Light wheel roller modified bulldozers, the main method is to cast iron bumps arranged in a certain order by the light wheel roller, the specific method described below. (1) Select the welding machine and welding rod in order to facilitate welding, reduce welding costs, shorten the welding
