Description
Technical field
The invention belongs to shield door design field, specifically a kind of screen door in rail transit.
Background technique
Shield door refers to surrounded on subway platform and train and fall through in a manner of glass curtain wall on platform between.Train reaches
When, electrically operated gate is then turned on glass curtain wall for the upper Train of passenger.However current shield door have certain risk, one
It can be accidentally gripped between shield door and train door when a little passenger loadings, have already appeared a lot of perils at present.
Such as 2007 Nian Yiming man be sandwiched in shield door and train when Shanghai Underground No.1 line is got on the bus before, train
After starting, passenger is extruded, and the tunnel that falls is died instantly.2 months in 2014 squeeze by force in Line of Nanjing Subway No.1 line, a man
Into subway, as a result it has been sandwiched between subway door and shield door.Fortunately platform security personnel on duty discovery in time, pulls open shielding by force
He has been dragged and has been come out, has been escaped by door.Passenger one occurs again for Foundation of Beijing Metro Line 5 during on November 6th, 2014 evening peak
Name woman is clipped among shield door and train door.After train operation, after subway starts, people is extruded rolling just as roller bearing.
After subway is outbound, that all rescue measures proved ineffectual is dead by woman！
After passenger is jammed, traditional shield door only has five seconds to the time of passenger self-rescue, has one on the inside of shield door
To the handle of yellow or red, it is only necessary to a gap is opened by shield door as soon as pulling out handle, train can be allowed to stop in emergency,
But some passengers are flurried due to facing a danger, or are difficult to first time pull handle back to handle and save oneself.
Summary of the invention

The cooperations of strip grooves 10 drives corresponding screw rod 6 to rotate, and under the action of being threadedly engaged, screw rod 6 is from corresponding tapped blind hole 4
Outer end is stretched out, what two outer end in contact for shrinking two screw rods 6 on door 1-2 can be reversed to corresponding contraction door 1-2 mono-
Power, the power can make a gap quickly occur between two contraction door 1-2, the train when shield door is opened a gap
It can stop in emergency, this is the security mechanism of subway, when passenger is gripped to shrink between door 1-2 and train door, is set by above-mentioned
Meter may be implemented train and start to start after a bit of distance that just emergency braking is braked, and the safety of passenger can be effectively protected, multiply
After visitor is rescued, all components can automatically reset under the action of torsional spring 9, while in the advertisement spraying area 25 in wide belt
Exploitation can be sprayed, with the continuous on and off of door 1-2 is shunk, 21 discontinuous operation of motor can drive wide belt anti-
Turn, vertical pivot 13 does not rotate with it when wide belt inverts, and realizes the advertisement in spraying area 25 in turn to passenger Accreditation Waiting Area outside shield door
It is shown in turn, improves the commercial value of shield door, the advertisement shown in turn can improve the attention of people, improve publicity
Effect makes shield door have multifunction.
Specifically, as shown, opening up the 4th blind hole 26 on 12 inner wall of first through hole described in the present embodiment, the 4th is blind
It is equipped with friction column 27 in hole 26, connects between the inner end of friction column 27 and corresponding 4th blind hole, 26 inner end by the way that spring 31 is fixed
It connects, the outer end of friction column 27 is engaged with corresponding 14 side of vertical tube.When by friction column 27 to the offer rotation of vertical tube 14
Resistance can guarantee that column cap 18 can smoothly increase corresponding vertical tube 14 with the cooperation of skewed slot 17.
Specifically, as shown, being connected between column cap 18 described in the present embodiment and corresponding vertical pivot 13 by bearing activity
It connects.The design can reduce the frictional force between column cap 18 and corresponding skewed slot 17, can further guarantee column cap 18 and skewed slot
17 cooperation smoothly increases corresponding vertical tube 14.
Further, as shown, 2 rear port of rectangular opening described in the present embodiment is coupled the tempered glass of rectangle
28.Tempered glass 28 can protect the components in rectangular opening 2, guarantee that the passenger of the outer Accreditation Waiting Area of shield door cannot directly connect
The components in rectangular opening 2 are touched, the passenger for avoiding waiting for area touches wide belt and contraction door 1-2 is caused to be opened.
Further, recessed as shown, the outer end face downside for shrinking door 1-2 described in the present embodiment opens up groove 29
Infrared distance sensor 30 is fixedly mounted in slot 29.Work as arrival of subway, when shrinking door 1-2 opening, two contraction doors 2 are apart from increasing
Add, infrared distance sensor 30 sends a signal to controller, is not shown in the figure, and controller control motor 21 rotates fixed circle
Number realizes showing in turn automatically for the advertisement sprayed in spraying area in wide belt so that wide belt be driven to rotate a certain distance.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
