K900悬挂式钢轨焊机是我国较早引进使用的钢轨接触焊接设备,可用于基地和移动焊接。该型焊机因具有结构紧凑,功率小,重量轻等优点,得到现场施工单位的青睐。但在使用中发现以下问题,其馈电装置磨损严重,成为非常易耗的部件。据调查,每副馈电装置在正常工作状态仅能完成3000个钢轨接头的焊接,而该部件此前依靠进口,价格高,而且供货周期长,成为该焊机在国内使用的瓶颈之一。馈电装置的磨耗不仅增加了焊接成本,而且容易导致焊接时馈电不均和夹紧不可靠产生打滑等问题,直接影响钢轨接头的焊接质量。
K900 hanging rail welding machine is introduced in China earlier use of rail contact welding equipment, can be used for base and mobile welding. This type of welder has the advantages of compact structure, small power, light weight and other advantages, and is favored by construction units at site. However, the following problems were found during use, and the feeding device was worn seriously and became a very easy-to-use component. According to the survey, each feeder can only finish the welding of 3000 rail joints in normal working condition, and the parts were relied on imports before, the price is high, and the delivery cycle is long, which has become one of the bottlenecks of the welding machine used domestically. The wear of the feeding device not only increases the welding cost, but also easily leads to the problem of uneven feeding and clamping unreliable slippage during welding, which directly affects the welding quality of the rail joint.
