Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figures 1 to 5, a kind of elevator overspeed protecting device, including rope speed detector, car body 1, sedan-chair
Compartment position detecting mechanism, carriage position-limit mechanism and electric life controller.The carriage position-limit mechanism includes consolidating at the top of car body 1
Surely the support tube 2 connected, the support rod 3 being socketed in inside the support tube 2, is arranged in leading for 3 axial ends of support rod
The mounting plate 5 on well enclosure is arranged in boots 4, and the guide rail for being arranged on the mounting plate 5, being used cooperatively with the guide shoe 4
6, the mounting plate 5 is located at 6 liang of lateral edge short transverses of the guide rail and is equipped with several accommodating cavities at equal intervals, in each accommodating cavity
Equipped with Horizontal rotation type gag lever post 7, the driving motor and the electric life controller of the gag lever post 7 are electrically connected.The steel wire
Rope speed detector and the electric life controller are electrically connected.
The car position testing agency includes the row's optical receiver 81 being arranged on well enclosure along short transverse, and is set
It sets in optical transmitter 82 of the car body 1 towards 81 side of optical receiver, the optical receiver 81 and the elevator control
Device processed is electrically connected.
When elevator speed is normal, gag lever post 7 is located inside accommodating cavity, and support rod 3 is normally moved with guide rail 6 and guide shoe 4
It is dynamic, guiding role is played to lift car.
When elevator overspeed operation, rope speed detector can send a signal to electric life controller, meanwhile, elevator controlling
