Wirerope, rope end combination, rope end pressing plate, drag hook, small torsional spring, link tube hold-down support, lifting rod and safety tongs lifting rod, it is described
Triggering linkage includes link tube, and the middle part of the link tube is connected to rope end pressing plate bottom, the connecting rod by lifting rod
Respectively there are a set of linkage mechanism in the two sides of pipe, and the linkage mechanism includes safety tongs lifting rod, and the link tube both ends pass through safety
Lifting rod and safety tongs fixed-link are clamped, the bottom of the frame is connected to the both ends of link tube, institute by link tube hold-down support
It states and is fixed with big torsional spring on link tube hold-down support.
Preferably, the wirerope is connected to the upper end of rope end combination.
Preferably, the upper end of the safety tongs lifting rod is hinged on safety tongs by safety tongs voussoir with waist hole.
Preferably, hole location more than two is provided on the link tube hold-down support, the big torsion spring set is in link tube
Both ends.
Preferably, the safety tongs is separately fixed on the inside of corresponding rack, the rope end pressing plate be located at two groups of racks it
Between, rope end pressing plate upper end two sides are equipped with H profile steel.
Compared with prior art, the beneficial effects of the present invention are: the present invention is when wire cable rupture, the rope being fixed together
Head pressing plate downlink, hits drag hook, makes drag hook that torsion be overcome to rotate, and lifting rod breaks off relations, and connects under the twisting force of the big torsional spring in two sides
Rod tube rotation, drives safety tongs lifting rod to lift safety tongs voussoir, acts two sides safety tongs, carriage or platform are clamped in H
On fashioned iron, stop carriage or platform, reaction speed is fast, can timely and effective braking carriage or platform.
Detailed description of the invention
