Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
A kind of mechanical type lattice door break proof safety device, as depicted in figs. 1 and 2, comprise column 4, lattice door 1 and anti-off device, column 4 has two, lattice door 1 is installed between two columns, the top of a column 4 is provided with drive motors 2 and reel 3, drive motors 2 is connected with reel 3, drive motors 2 is with movable reel 3 to rotate, anti-off device comprises lock 5 and lock dog fixed axis 8, lattice door 1 two ends respectively arrange a lock dog 5, described lock dog 5 is arranged on lock dog fixed axis 8, one end of lock dog fixed axis 8 is welded mutually with lattice door, the intrinsic multidiameter of the other end of lock dog fixed axis 6, ladder the tip of the axis and lock dog 5 are hinged, and hinged place is provided with self-lubricating bearing 9, to play minimizing mechanical oscillation, reduce noise, preventing pollution, transfer membrane can be formed in operation process, play the effect reducing friction.
Lock dog 5 comprises flip flop equipment and locking device, flip flop equipment is connected by connecting axle 14 with locking device, flip flop equipment comprises support roller 10 and fixed head 11, support roller 10 is connected with fixed head 11 by roller shaft, support roller 10 is between two pieces of fixed heads 11, and support roller 10 contacts with wire rope 7, and support roller 10 can rotate around roller shaft, to reduce the friction between support roller 10 and wire rope 7, reduce the wearing and tearing of wire rope 7.One end of connecting axle 14 is welded mutually with locking device, the other end is also fixing through the circular hole on fixed head 11, locking device one end arranges hook 15, the other end is hinged by hinge hole and lock dog fixed axis 8, one end of wire rope 7 is around on the reel 3 on column 4 top, and the other end is arranged on another column 4 top.
Column 4 is welded with several hook axles 6, column 4 is from top to bottom uniformly distributed, preferably, hook axle 6 is hollow cylinder, just with processing, saves material, is also beneficial to the weight alleviating single unit system.
