Description
Technical field
The invention belongs to technical field of elevator equipment, and in particular to protective device when a kind of lift car stall.
Background technique
Elevator is the mechanical equipment commonly arrived in life, is widely used in the every aspect of life.
Acceleration transducer is a kind of sensor that can measure acceleration.Usually by mass block, damper, elasticity member
The parts such as part, sensing element and suitable tune circuit form.Sensor passes through the survey to inertia force suffered by mass block in accelerator
Amount obtains acceleration value using Newton's second law.
Elevator stall refers to that elevator is risen or fallen with transnormal speed, the accident of elevator stall still frequent occurrence,
Existing design protection is complex, therefore it is particularly significant to design a kind of safe and reliable falling protecting device.
Summary of the invention
In order to meet above-mentioned requirements, the present invention provides a kind of used during elevator falling stall protector, which can be in elevator
Fall stall when, so that carriage is stopped in time, protect the safety of passenger.
The technical solution adopted by the present invention to solve the technical problems is: a kind of used during elevator falling stall protector, including
Carriage and hoistway, the carriage is interior to be equipped with acceleration transducer, and the acceleration sensing is connected with controller, the cage bottom
If there are two the same rotating electric machine of structure, the structure of rotating electric machine are as follows: rotary shaft is equipped with screw thread, rotates and is equipped at axle thread
Axle sleeve, if rotary shaft, which is equipped in the carriage, is equipped with acceleration transducer, the acceleration sensing is connected with controller, described
Controller is connected to the battery, and controller and battery are set in carriage, and the cage bottom sets that there are two structure is the same
Rotating electric machine, two rotating electric machines are connected with controller, the structure of rotating electric machine are as follows: rotary shaft is equipped with screw thread, rotary shaft
Axle sleeve being equipped at screw thread, rotary shaft is equipped with several telescoping mechanisms, the specific structure of telescoping mechanism are as follows: axle sleeve is equipped with shaft A,
