摘　　要：在现有的掘进机行走部张紧限位机构的基础上,介绍了一种新的张紧限位结构,该结构在掘进机工作时能够避免张紧油缸受力,有效避免垫板因受力而变形影响使用,还可避免张紧油缸因受到冲击载荷而损坏。A new tension structure was introduced which was based on the foundation of madheader travelling part of tension structure. This tension structure would avoid tension cylinder not to fight force and would avoid the plate to become deformed because of the force, and then avoid tension cylinder not to be damaged.
