introduction:Qinling tunnelILine useTB880EHeading machine,After nearly two years of construction use,When the machine was found to be crossing a bad area,There is an underutilization of the boot and a reduction in propulsion、The problem of doubling tunneling time。Especially in the hard rock conditions of Qinling Mountains,Crossing time,Two thirds of the way through the boot,The thrust is less than two-thirds of what its supposed to be,When the palm face rock is hard and requires a large push,The excavation time is significantly more than twice the time required for similar rocks in the past,At the same time, tool wear is more serious than similar rocks。According to the analysis, it is caused by the unreasonable design of the propulsion hydraulic system of the machine,The following analysis of the reasons
