Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As Figure 1-3, a kind of device for being used to prevent children from falling on escalator of the present utility model, including located at
Air cushion 9, level in next floors ceilings are layed in the life net 11 immediately below air cushion and carrying for lifting life net
Net mechanism 12, air cushion one end, which is fixed on, to be faced on the ceiling of dummy section side, and is connected with electric gas-filled cylinder, and life net network interface is in
Square, and length and width is all higher than facing dummy section horizontal cross-section between staircase, Ti Wang mechanisms include laborsaving gear train, can be unidirectional
The ratchet mechanism of self-locking, rescued respectively with coaxially connected the carrying net handle, rope and catch on of laborsaving gear train and ratchet mechanism
The hook of raw net one end, Ti Wang mechanisms, which are fixed on, is fallen on floor passage metope, and the Ti Wang mechanisms can be prevented in life net lifting
During slide and drop because of operation miss, the gearratio of laborsaving gear train preferentially selects 1:10；
Children after dummy section drops, enter row buffering by air cushion, reduce impulsive force, prevent children due to punching from facing between staircase
Power second hurt when intercepting is hit, due to cushion stiffness deficiency, after air cushion buffers, lifesaving that the children that fall are fallen into below air cushion
Net, therefore, the children that fall successfully obtain flexible hold-up interception, and by putting forward net mechanism lifts life net, the children that will fall are pulled up to can people
The position that power is rescued, deploy work of suing and labouring so as to convenient.
As further technical scheme, in order to improve the aesthetic property of staircase, prevent air cushion from influenceing the visual field above and below staircase,
The buffering effect of air cushion is further improved simultaneously, and air cushion, which is arranged to folding, can store form, and it is inflating expanded to meet an urgent need, swollen
Buffered during swollen, buffering effect more preferably, in the program also includes controller and faces dummy section falling object for detecting staircase
Detecting element, detecting element 3 are installed on the guard rail of both sides staircase exit and entrance, and detecting element prioritizing selection number is to penetrating
Formula photoelectric sensor, it is several to be divided into upper group, two groups of the following group to correlation photoelectric sensor, wherein every group is at least two pairs of correlation light
Electric transducer, the horizontal range between correlation photoelectric sensor is 10cm, and is not more than 30cm with guard rail minimum distance, on
Group with guard rail topmost away from 20cm, the following group with guard rail topmost away from 30cm, controller be electrically connected detecting element and
Electric gas-filled cylinder, air cushion, which can crispatura, to be accommodated in positioned at facing in the air cushion box on the ceiling of dummy section side, and it is included along inflation side
To the Expansion bar 91 for setting the air cushion roll bar 92 of reinforcing air cushion intensity and being connected with electric gas-filled cylinder, when detecting element has detected
Falling object, signal is sent to drive electric gas-filled cylinder quickly toward inflating in the Expansion bar of air cushion, the air cushion for storage of crispaturaing is opened up rapidly
Open and by being gone out in air cushion box, the very first time intercepts to the children that fall, delay fall speed and impulsive force, prevent from falling
Virgin body is during interception by secondary injury；
As further technical scheme, face on the ceiling of dummy section side the placement being additionally provided with for storing life net
Frame 1, the stretching, extension of life net one end are fixed in shelves, and two ends angle of the other end is individually fixed in be connected with shelves bearing 8
Two cylinders 4 on, by controlling the collapsing length of cylinder, can easily adjust life net extension elongation or storage expansion
Life net, certainly, for further staircase attractive in appearance and ensure the staircase visual field, life net may be alternatively provided as storage and place, exhibition of meeting an urgent need
The mode opened, is provided with the block baffle plate 6 for being used for covering gear life net accommodation space in shelves, and block baffle plate passes through with shelves
The energization magnetic of electromagnet 7 connects, and cylinder is provided with the magnetic valve for cutting through pneumatic source, and electromagnet and magnetic valve are electric with controller respectively
Property connection, in order to allow electromagnet dead electricity when, block baffle plate automatically opens up, block flapper closure when to have with vertical direction be in 5-
15 ° of oblique angle, automatically opened up under block baffle plate deadweight during dead electricity, wherein, 10 ° of oblique angle prioritizing selection, therefore, work as detecting element
Falling object has been detected, signal has been sent and causes electromagnet dead electricity, block baffle plate automatically opens up, meanwhile, magnetic valve obtains electric, cylinder work
Plug stretches out with two ends of life net other end angle, and expansion carries out secondary interception immediately below air cushion, and is drawn high through Ti Wang mechanisms,
Can successful rescue fall children.
It the above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of the art
For member, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improvements and modifications
