Description
Technical field
The present invention relates to towed elevator field, the elevator of safety air cushion is had in more specifically to a kind of carriage.
Background technique
In the safety prevention measure of existing elevator, when the speed of carriage is more than 1.3 times of normal speed, electrical actuation is forced
Power supply is cut off, the band-type brake on traction host is made, clamps traction machine main shaft；When the speed of carriage is more than 1.4 times of opportunitys of normal speed
Tool actuation makes the safety tongs actuation in carriage, clamps rail using brake shoes；It is slow in pit when carriage drops to pit
It rushes device and carriage reaction force is provided, to reach the unexpected generation for avoiding carriage from smashing, but these safety measures are only capable of passively providing
The safety of occupant in carriage can not actively provide personnel protection in carriage.
Summary of the invention
The present invention provides a kind of interior elevator for having safety air cushion of carriage in view of the deficiencies of the prior art, of the invention
The wind-force that elevator in carriage with safety air cushion is generated when elevator quickly being dropped using wind-drive device is pressed into the peace in carriage
Full air cushion protects the personnel in carriage not to be hit injury.
The specific technical solution of the present invention is as follows: a kind of interior elevator for having safety air cushion of carriage, including carriage, the sedan-chair
Safety air cushion is installed, the safety air cushion is located at below the bottom surface and side of the carriage, and the safety air cushion in compartment
Lower section is equipped with inflating port and is connected to outside the carriage；
Lower section is equipped with check valve outside the carriage, and the check valve includes air inlet and air outlet, the gas outlet
It is connect with the inflating port；
Wind-drive device is installed, the wind-drive device includes collection wind umbrella sum aggregate wind umbrella cover below the check valve；
The collection wind pack includes the portion of strutting and ventilation interconnecting piece, and portion upper end and the ventilation interconnecting piece lower end of strutting connects
Logical, the ventilation interconnecting piece upper end is connect with the air inlet of the check valve, the portion of strutting have collapse with it is distracted
State.
Under elevator normal operating conditions, the collection wind umbrella is in rounding state；Under the quick fall condition of elevator, the collection wind
The portion of strutting of umbrella is in softened state and carries out collection wind.
As a preference of the present invention, the collection wind umbrella cover is the circular cone flake that centre is provided with through-hole, it is sleeved on the collection
Wind umbrella periphery；The collection wind umbrella cover tapered opening is installed downward, and is connected with spring between upper end and the check valve.
When elevator lapse rate is unhappy, the collection wind umbrella cover is located at the collection wind umbrella distraction surface under the thrust of the spring
On；When elevator lapse rate is too fast, the wind-force that the collection wind umbrella cover is subject to is greater than the thrust of the spring and moves up, and moves to described
When collecting wind umbrella distraction surface or more, the collection wind umbrella struts completely.
As a preference of the present invention, when the cage descending speed is greater than 1.2 times of maximum falling speed under normal condition,
The collection wind umbrella cover, which compresses, moves to the collection wind umbrella distraction surface or more on the spring, and the collection wind umbrella struts completely；
The cage descending speed is 1.2 times of maximum falling speed under normal condition and the collection wind umbrella struts completely
When, the wind-drive device enters 1.1 ~ 1.5 times that wind pressure is elevator rated load.
As a preference of the present invention, the check valve is that the air inlet is ventilated to the gas outlet direction, the outlet
Mouth is ventilated to the air inlet direction to be ended.
Air-flow can only enter inside the safety air cushion from the wind-drive device and can not flow out as a result, to the safety
Air cushion is inflated.
As a preference of the present invention, the wind umbrella cover that integrates is rigid plastics, and bevel angle is 100 ° ~ 160 °.
As a preference of the present invention, the wind umbrella cover that integrates is rigid plastics, and bevel angle is 120 ° ~ 150 °.
As a preference of the present invention, it is described strut portion by flexible film be covered on circumference array distribution reinforcing rib on group
At the portion of strutting struts rear outer surface and offsets with the collection wind umbrella cover inner surface, maximum distraction angle and the collection wind
Umbrella cover angle is identical.
The portion of strutting is played a supporting role at intermediate position after strutting by the collection wind umbrella cover as a result, is strutted described in reinforcement
The stability in portion will not turn over because wind-force is excessive.
As a preference of the present invention, being covered with protective pad, the protective pad on the safety air cushion of the cage bottom
For soft material.
It will not directly be trampled on the safety air cushion when people walks in the carriage as a result, the safety will not be made
Air cushion friction and it is damaged.
As a preference of the present invention, fitting is installed on the carriage bottom surface, two sides when the safety air cushion unaerated
And medial surface, and side mounting height is greater than 1m.
In conclusion the invention has the following advantages:
The wind that elevator in carriage of the invention with safety air cushion is generated when elevator quickly being dropped using wind-drive device
It forces and the personnel in carriage is protected not to be hit injury into the safety air cushion in carriage.
