1制动梁安全链卡子松动问题L—B型组合式制动梁安全链原组装方式为吊座与梁体组焊在一起,现已改为通过眼环螺栓紧固卡子而成(图1)。此举解决了原梁体焊接部位频繁出现裂纹的质量问题,但是由于新的连接方式在设计和制作工艺方面存在问题,导致制动梁安全链卡子在运用过程中经常出
1 Brake Beam Safety Chain Lock Loose Problem The assembly method of L-B type composite brake beam safety chain is that the hanging bracket and the beam body are welded together and has been changed to be fastened by eye ring bolts (Figure 1 ). This solution to the original beam body welding parts frequently crack quality problems, but because of the new connection in the design and manufacturing process there are problems, resulting in the brake beam safety chain often stuck in the process of using the card
