Elevator with airbag protector

Abstract

An elevator with an airbag protector comprises the airbag protector. The airbag protector comprises a safety airbag and speed measurement encoders; the safety airbag is fixed on the outer surface of the bottom of the car; the safety airbag is electrically connected with a safety airbag trigger device; the speed measurement encoders are arranged on the top of the car or columns; the output end of every speed measurement encoder is connected with a safety airbag trigger controller which is electrically connected with the safety airbag trigger device; the speed measurement encoders are movably connected with a main frame. The speed measurement encoders each having a roller measures the speed when rolling up and down within the main frame; the safety airbag protects the elevator; the elevator is simple in structure and convenient to mount. After inflated, the safety airbag has the effect of absorbing impact force so that the car lands stably and generates no direct impact to passengers inside. The elevator is available as various elevators, especially home elevators.

Description

Technical field [0001] The present invention involves an elevator with a airbag protection device. Background technique [0002] Elevator is an indispensable vertical transportation vehicle for high -rise buildings. It is directly related to human life safety. Most of the existing elevators rely on devices such as safety pliers, speed limiters, buffers, and other devices to protect the safety of the occupants.The speed limiter is used to detect whether the car is super speed, and it does not work when the elevator runs normally.When the elevator runs more than the rated speed and reaches the risk value (that is, the speed limiter action speed), the speed limiter operates the electrical switch to turn on the rapid parking circuit to stop the motor;The stop execution agency, when the speed is limited, is sandwiched on the guide rail through a safe pliers, forcing the elevator to stop.The buffer is the last safety device at the elevator limit position. It is installed in the bottom ...

AI Technical Summary

Problems solved by technology

In addition, when installing the above-mentioned devices, it is necessary to dig the bottom pit of the well, arrange rigid guide rails, etc., and the construction is very cumbersome

Moreover, due to the small buffer stroke and poor buffer performance of the hoistway bottom pit, it is easy to cause damage to the elevator car falling due to speed, resulting in casualties of passengers in the elevator car

[0004] At present, some elevators use anti-vibration rubber for shock absorption, and install the anti-vibration rubber on the bottom of the car to isolate the vibration generated by the elevator guide shoes; however, due to the small buffer stroke and poor buffer performance of the anti-vibration rubber, it often causes passengers Casualties occur

[0005] The existing patent literature discloses that an airbag is installed on the inner surface of the bottom of the elevator car. When the elevator is in danger of falling suddenly, the airbag on the inner surface of the bottom of the car is inflated instantly, which will not only cause direct damage to the passengers in the car. The impact force may cause direct damage to the life safety of passengers; moreover, due to the violent impact between the car and the bottom of the main frame, it will cause great damage to the car and the main frame itself, and the maintenance cost is high
