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。 On the basis of the existing tensioning mechanism for the driving part of roadheader, a new tensioning limit structure is introduced, which can avoid the stress of the tensioning cylinder when the boring machine is working and effectively avoid Force and deformation affect the use, but also to avoid tensioning cylinder due to impact load damage.
