Number single inspection rule regulation of modification is just verified when 2 years maintenance units of elevator greater than 3m/s speed, and reviewer does not need
Field-checking process carries out field observation)；
(2), it since the variation of wirerope itself extends, causes tensioning apparatus to contact to earth, keeps steel wire rope tension inadequate, generation is beaten
It is sliding；
(3), limiter of speed rope-clamping pliers brake force is inadequate, can't clip limiter of speed steel cable.When limiter of speed operation time limit speed device steel cable
It skids in limiter of speed race and is unable to lift safety tongs, cause failure；
(4), the lifting throw of lever is inadequate, and apart from excessive, lifting is not in place, makes for active laver end and safety tongs linked switch
Voussoir does not reach trackwork face, and when torque arm lifts, switch cannot be moved at the same time；
(5), since the abrasion of speed limit device wheel race, the position of speed limiter wire rope decline, rope-clamping pliers do not reach steel cable
Or brake force is inadequate, and limiter of speed steel cable is caused to skid；
(6), speed limiter wire rope position makes rope-clamping clamp less than limiter of speed steel wire not within the scope of rope-clamping pliers effective width
Rope, causes to fail；
(7), high-rise high speed elevator speed limiter wire rope is long, and cost improves, and amplitude is big, be easy to cause malfunction.
In order at least solve above-mentioned subproblem, the application devises a elevator emergency stop protective device.
