connecting a curtain hanger J10 with a channel steel long arm J20 by using an adjusting bolt J19;

one end of the curtain J9 is wrapped by a curtain hanging rod J11 and then is fixed on a curtain rolling hanger J10 by a curtain fixing seat J12, and the other end of the curtain J9 is wound on a curtain rolling shaft J6 and is fixed;

connecting the winch J2 and each limit switch to a control system;

at this point, the installation of the curtain winding mechanism of the underground lifting curtain winding device 10 is completed. The winch J2 of the curtain winding mechanism winds and unwinds the curtain steel wire rope J8 and pulls the steel wire rope reel J7 and drives the curtain winding reel J6 to rotate after the direction of each rope pulley group is changed, and therefore the curtain J9 can be unfolded and folded.

Therefore, the underground lifting curtain rolling device 10 is installed, and the underground lifting curtain rolling device 10 can normally operate after the underground lifting curtain rolling device is adjusted by the two systems of the lifting mechanism and the curtain rolling mechanism. The working process is as follows: opening the hydraulic station → the working platform carries the rolling screen mechanism to rise to the set height → the hydraulic station pressure maintaining valve is opened, locking the raised screen frame height position → the winch works, putting down the rolling screen shaft to the set position, simultaneously unfolding the rolling screen and locking until the projection is finished → opening the folding key, unlocking the rolling screen → the winch works, rolling up the rolling screen shaft to the initial position → locking of the working platform height position is cancelled, and the working platform returns to the initial position → closing the hydraulic station → finishing.
