After installation, the bar portion of the contiguous block of T-type structure vertically has certain activity relative to open-work, when hydraulic prop pressure release
When, contiguous block moves down with hydraulic prop, after the cap portion of contiguous block contacts with crossbeam, because the cap portion of contiguous block can not be from saturating
Hole passes through, and crossbeam is played hydraulic prop and pulls, while pulling block on crossbeam and chain also rise to hydraulic prop and pull work
With, so as to effectively prevent from toppling over during hydraulic prop, guarantee tunnel safety.
3rd, the utility model is simple in construction, reasonable in design, easy to use, simple installation, can effectively ensure that colliery lane
Road safety, ensures being smoothed out for safety in production, reduces the occurrence probability of danger.
