Description
Technical field
The present invention relates to elevator safety field, particularly a kind of gasbag-type emergency staircase carriage body.
Background technology
Elevator is vertical transport instrument, and carriage is the pith of passenger loading, therefore the safety of carriage is most important.
Carriage moves up and down along guide rail in running process of elevator, and passenger stands and moved in car floor with carriage.When lift car to
During lower operation, due to hoist ropes break rope, car overload, safety tongs limiter of speed be failure to actuate, between traction sheave and hoist ropes skid, make
Dynamic device failure, brakeless torque and limit switch such as do not work at the reason, and carriage can be caused out of control and fallen to pit.This fashionable dress
Buffer in pit below carriage can mitigate the impact between carriage and pit, but only by the buffering of buffer offer
Effect still cannot be guaranteed that carriage and passenger are injury-free.Carriage will be impaired serious particularly when buffer breaks down, even
Threaten the life of people.
The content of the invention
The shortcomings that it is an object of the invention to overcome the prior art, there is provided one kind is to solve deficiency of the prior art,
A kind of Elevator safety airbag device that people's safety can be ensured more effectively in the case of used during elevator falling is provided.
The purpose of the present invention is achieved through the following technical solutions：A kind of gasbag-type emergency staircase carriage body, including cage
Body, upper air bag group, lower gasbag group, friction air bag group, gas tank, inductor, spare electronic box, the gas tank are installed on outside elevator car
At the upper right corner of side, it is fixed on by riveting-rack above elevator car, inductor is riveted on the elevator car upper left corner by stent
Place, upper air bag group are installed on the bottom plate of elevator car in the following, being internally provided with fine crack with elevator car, lower gasbag group is arranged on
Elevator car external world bottom, is installed parallel to elevator car bottom, and elevator car both sides also set up the first plenum space, and first fills
Headroom is provided with connector with friction air bag group respectively, and the first plenum space external world also sets up the second plenum space, and second fills
There is connector in headroom in bottom and upper air bag group, lower gasbag group respectively, and gas tank bottom also sets up gas-guide tube, set above gas-guide tube
Put control valve；The outside of the elevator car both sides is additionally provided with rubber layer, outside the second plenum space parallel with rubber layer
Wall is connected, and outer wall is arranged to elastic outer wall.Inductor is arranged to acceleration transducer, and inductor is additionally provided with conducting wire and gas tank
Control valve connection.Gas-guide tube is arranged to three outlet shapes, and gas-guide tube one outlet is connected to above gas tank, and in addition both sides go out
Mouth is connected in the first plenum space and the second plenum space.Elevator car inside top is also equipped with stand-by lamp, spare
Lamp is connected by conducting wire with spare electronic box.Inductor is also connected with spare electronic box by conducting wire.
The present invention has the following advantages：：For elevator in daily operation, the acceleration of operation is generally all smaller.But
When elevator tenesmus out of control, acceleration of gravity will increased dramatically, at this time gravity acceleration sensor its detect that gravity adds
Speed exceedes early warning threshold values, then sends a signal for exceeding early warning threshold values from gravity acceleration sensor to control module.Gas
Capsule module is made of gas generator and air bag, and control module sends work order to gas generator, from gas generator to
Fast aeration in air bag, so that air bag quickly launches opening.Speed of the elevator car when falling has been buffered, has been reduced anti-
Shake the danger triggered.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
In figure：1- lower gasbag groups, the upper air bag groups of 2-, the first plenum spaces of 3-, 4- elevator cars, 5- rubber layers, 6- second are inflated
Space, 7- stand-by lamps, the spare electronic boxs of 8-, 9- gas tanks, 10- control valves, 11- gas-guide tubes, 12- inductors, 13- friction air bags
Group.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
State.
As shown in Figure 1, a kind of gasbag-type emergency staircase carriage body, including elevator car 4, upper air bag group 2, lower gasbag group 1, rub
Air bag group 13, gas tank 9, inductor 12, spare electronic box 8 are wiped, the gas tank 9 is installed at the 4 outside upper right corner of elevator car, passes through
Riveting-rack is fixed on above elevator car 4, and inductor 12 is riveted on 4 left upper of elevator car, upper air bag group 2 by stent
Bottom plate installed in elevator car 4 with elevator car 4 in the following, be internally provided with fine crack, lower gasbag group 1 is arranged on elevator car
4 extraneous bottoms, are installed parallel to 4 bottom of elevator car, and 4 both sides of elevator car also set up the first plenum space 3, and the first inflation is empty
Between 3 respectively with friction air bag group 13 be provided with connector, 3 external world of the first plenum space also sets up the second plenum space 6, and second fills
There is connector in headroom 6 in bottom and upper air bag group 2, lower gasbag group 1 respectively, and 9 bottom of gas tank also sets up gas-guide tube 11, gas-guide tube
11 set control valve 10 above；The outside of 4 both sides of elevator car is additionally provided with rubber layer 5, and parallel with rubber layer 5
Two plenum spaces, 6 outer wall is connected, and outer wall is arranged to elastic outer wall.Inductor 12 is arranged to acceleration transducer, and inductor is also
The control valve 10 for being provided with conducting wire and gas tank connects.Gas-guide tube 11 is arranged to three outlet shapes, and 11 one outlet of gas-guide tube connects
It is connected on above gas tank 9, in addition two side outlets are connected in the first plenum space 3 and the second plenum space 6.Elevator car 4
Inside top is also equipped with stand-by lamp 7, and stand-by lamp 7 is connected by conducting wire with spare electronic box 13.Inductor 12 also with spare electronic box
13 are connected by conducting wire.
The course of work of the present invention is as follows：When accident occurs in elevator, elevator freely falling body, is at this moment arranged on cage
Inductor 12 at the top of body measures acceleration at that time, when acceleration reaches the numerical value set, the control inside inductor 12
Molding block opens the control valve 10 for being arranged on gas tank bottom.
On the other hand, the nitrogen in gas tank, enters the first plenum space 3, and the friction gas of the first plenum space 3 connection
Capsule group 13 produces expansion so that the increase of rubber layer 5 and elevator frictional force, the less speed to fall.
Another further aspect, control valve 10 are opened, and gas tank 9 inflates the second plenum space so that is arranged on 4 bottom of elevator car
