No elastomeric O-type ring and washer on bolt two (19)；The spiral shell with elastomeric O-type ring and washer is arranged in monitor and adjusting bolt
Bar opens and closes machine base one end；
2. the screw open-close machine (1) is hand screw open-close machine, when gate is normally run down, flashboard is than heavier, hand spiral shell
Bar headstock gear bears the flashboard gravity of gate screw rod connection, and screw open-close machine pedestal is supported by bottom beam, standing screw headstock gear bottom
The fixing bolt one (6) and fixing bolt two (19) of seat and bottom beam do not stress；
3. when card lock occurs, flashboard (4) is no longer run down, and hand screw open-close machine continues to turn down gate screw rod (3),
Screw open-close machine pedestal will receive a upward power in the case；Screw rod opening and closing at this time with elastomeric O-type ring and washer
The side of machine base, elastomeric O-type ring by screw open-close machine pedestal it is upward deformation occurs so that the screw open-close machine of the side
Pedestal has a displacement upwards；
4. the upward displacement of screw open-close machine pedestal acts on the adjusting bolt (11) connecting with monitor, bolt is adjusted by spiral shell
The pressure that the upward displacement of bar opening and closing machine base generates is transmitted on monitor；
5. monitor issues alarm signal, operator is notified to stop hand screw open-close machine, to prevent screw rod from further being pushed up
It is curved.
