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

Embodiment 1

[0029] Reference figure 1 As well as figure 2 As well as image 3 , A elevator with a airbag protection device, including power mechanism 1. Main framework 2, car 3, and connecting rack 6, power mechanism 1 connects to the top 3-1 of the car through the steel wire rope 4, and the pillar 3 of the car 3-2 Installed a flexible orientation wheel 5, the car 3 is installed in the main frame 2, and also includes the airbag protection device, which includes airbag protection device including airbag 7 and speed coder 9, airbag 7 fixed in the sedanThe bottom 3-3 outer surface of the compartment 3, the airbag 7 is connected to the trigger device 8 of the airbag, the speed coder 9 is set on the top 3-1 of the car 3 or the pillar 3-2, and the output end of the speed coder 9The airbag trigger controller 10, the airbag trigger controller 10 is connected to the airbag trigger device 8, and the speed coder 9 is connected to the main body frame 2 through the roller (not shown in the figure).

[0030...

Embodiment 2

[0037] The difference between this embodiment and Example 1 is:

[0038] Two-speed encoder 9 is symmetrically installed on the pillar 3-2 of the car 3.

[0039] The airbag is located on the bottom surface of the main frame 2.

[0040] The rest of the embodiment 1.

Embodiment 3

[0042] The difference between this embodiment and Example 1 is:

[0043] The trigger device of the airbags 8 is the gas valve (not shown in the figure), the air valve and the airbag trigger controller 10 are connected, and the gas valve is installed on the gas pipeline (not shown in the picture).Connected to the high -pressure gas cylinder (not shown in the picture), the other end of the gas pipeline is connected to the airbag 7.The airbag 7 is released from the gas stored in a high -pressure gas cylinder to complete the inflatable.When the airbag trigger controller 10 receives the speed measurement signal from the speed measurement coder 9, the opening of the control valve is turned on, and the airbag 7 is inflated through the high pressure cylinder.

[0044] The rest of the embodiment 1.

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 ...
