8 can judge that the problem of resolving rope occurs in elevator, and promptly friction wheel apparatus is braked by brake 6 and brake disc 3, increased
Add frictional force of the friction wheel apparatus to steel wire rope 10, so as to play the function of anti-break rope.Meanwhile the utility model can also avoid
It is dangerous to caused by the maloperation of elevator, for example do not close the door suddenly up or descending, preferable protecting effect is played, in this reality
Apply in example, switch board 8 can obtain the signal of the first encoder 9 and the signal of the switch gate of lift car 23 in real time, be rubbed when detecting
Wipe wheel apparatus to rotate and elevator door when not shutting, now brake hard hoist engine 22, prevent lift car 23 continue it is up or
It is descending, so as to which the operation played to elevator carries out the function of duplicate protection.
The utility model device is connected by setting balancing weight, and around friction wheel apparatus with hoisting container, can be right
Hoisting container is carried out in lifting process, reduces torque and the acting of lifting means, so as to extension device service life, saves dress
The power consumption put.Meanwhile first encoder setting, the motion conditions of friction wheel apparatus can be detected in real time, and by the shape of detection
State with elevator second encoder detection state compared with, when the first encoder detect friction wheel apparatus stop,
When second encoder detects that elevator keeps rotating simultaneously, illustrate the stuck situation of hoisting container occurred, control in time carries
The machine of liter parking, so as to realize the function of rope creep protection.In addition, the first encoder can also detect that friction pulley device rotary speed increases suddenly
It hurry up, illustrate the situation of the disconnected rope of main rope occurred, and control brake carries out brake operating in time, so as to avoid hoisting container
Situation about falling.
