Compared with prior art, advantageous effect possessed by the utility model is：
It is support with sleeve using hydraulic pressure as power, is extracted hydraulic support axis pin to sleeve by operating jack, both
It can provide and stablize, reliably export power, and save human and material resources.The application of hydraulic pressure pin pulling out device simultaneously, it is ensured that pull pin
The personal safety of process, the chain rupture that prevented to pull pin, damage pull pin bolt the phenomenon that.Coming into operation for hydraulic pressure pin pulling out device improves
Personnel safety factor during holder disintegration, reduces construction link, greatly reduces the labor intensity of worker, improve and pull out
Effect and efficiency are sold, has prevented to do over again.
