Action, drives anchor cable mechanism slips of hiding to be adjusted, and anchor cable mechanism of hiding is adjusted the specific position for anchor cable casing of hiding by regulation jack
Put, the anchor cable on top plate can be hidden, make anchor cable is intact after frame is moved to retain, the setting prop again after anchor cable casing of hiding determines position；
Then complete the drop frame of support, move frame, rise frame action, at the same support drop post and during setting prop cant beam, front rod, back link also with
Action, regulate and control the balance of preceding back timber and rear back timber, prevent arch support.Net laying mechanism using manual operating valve control come
Realize the lapping to tunnel.One-level telescopic jack, two grades of telescopic jacks control stretching for one-level casing and two grades of casings respectively
Contracting amount.
Beneficial effects of the present invention are as follows：Realize that face end support is closed with support with mesh-layingdevice using the structure design of rational support
It is integrated.The present invention reduces the structural member of support, accomplish that a frame is dual-purpose, reduce support input cost；Pass through electrichydraulic control skill
Art, supporting mechanism adjust automatically, improves operating efficiency；Hide anchor cable hydraulic mechanism, tunnel anchor cable/rod is stood intact preservation,
The purpose of protection top plate is reached, so that the problem of solving safety in production；The present invention occupies little space, underground dismounting maintenance side
Just.
