The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.
As shown in Figure 1, be existing Three-claw type rotating disk retention device, be provided with three clavate pawls 200 on rotating disk 100.When this retention device is used on subway gate, gate passage current had certain obstruction.In order to overcome its defective, the utility model provides a kind of subway gate scissors door, and details are as follows for its technical scheme:
For ease of understanding, in following technical proposals, all with flabellum) the state that is blocked of " opening " corresponding gate passage, with the state of " withdrawal " corresponding gate passage P Passable of flabellum.
Embodiment one
To shown in Figure 5, subway gate scissors door of the present utility model comprises that one is used for fixing base 1, is provided with a side plate 7 on base 1 as Fig. 2.Base 1 is provided with a main shaft 2, and having connected one on main shaft 2 can be around the blade rack 3 of main shaft 2 rotations.Be connected with a flabellum 4 on blade rack 3.Flabellum 4 is that a centre has the metallic framework surface by the segment of foamed material parcel.When flabellum 4 is positioned at retrieving position, do not exceed the outer of side plate 7.
Side plate 7 is provided with a flabellum locator slide 10, and flabellum 4 is slidably connected by a flabellum location bearing 11 and described flabellum locator slide 10.When flabellum 4 was opened or regained, its movement locus can strictly be limited in the allowed band of flabellum locator slide 10.The action that so just can guarantee flabellum 4 keeps uniformity and stability highly.
Be provided with a motor 8 that is used for driving flabellum 4 motions on side plate 7, be connected with a drive connecting rod 15 on its output.Be articulated with a passive connecting rod 16 on drive connecting rod 15.The first end of passive connecting rod 16 and a drive link 18 is articulated.Drive link 18 is parts that are similar to the shape of letter " V ", intermediate position (i.e. the waist break of " V " shape) is connected on side plate 7 by a drive link fixed axis 17, and drive link 18 just can be rotated around drive link fixed axis 17 like this.The second end of drive link 18 is connected with flabellum drive link 6.Blade rack 3 is connected with flabellum drive link 6 by flabellum driving shaft 5.Preferably, as shown in Figure 6, blade rack 3 is provided with a vertical flabellum that extends and drives slideway 13, and flabellum driving bearing 5 slidably is arranged on flabellum and drives in slideway 13.When flabellum 4 was opened or regained, flabellum driving bearing 5 drove the interior slip of slideway 13 at flabellum, produces dislocation to prevent flabellum 4 and blade rack 3 in motion process.
When flabellum 4 was opened or regained, flabellum location bearing 11 produced dislocation in the interior slip of flabellum locator slide 10 to prevent flabellum 4 and blade rack 3 in motion process.
When motor 8 rotated, power made flabellum 4 to open or to regain under the control of motor 8 along the route transmission of " drive connecting rod 15 → passive connecting rod 16 → drive link 18 → blade rack 3 → flabellum 4 ".
In such scheme, if for simplified structure, can directly main shaft 2 be fixed on side plate 7, save base 1.The fixing of whole subway gate scissors door just relies on side plate 7 to realize.But all the other not mentioned parts that are connected on base 1 shown in the accompanying drawings can be directly connected on side plate 7.This alternate embodiments is among the protection domain of the present embodiment equally.Although the fixing reliability of this mode slightly descends, having omitted base 1 afterwards can Cost reduction.In embodiment described later, those skilled in the art are easy to judge, and the part of fixing on base 1 that all are mentioned can be replaced with the mode that is fixed on side plate 7, within being in equally technical scope of the present utility model, do not affect the realization of the utility model technical purpose.
Embodiment two
On the basis of embodiment one, gate passage can not be closed in order to prevent from cutting off the power supply suddenly, as shown in Figure 2, be connected with a power-off restoration spring 12 on passive connecting rod 16 and between base 1, this power-off restoration spring 12 is in the state that is stretched, required pulling force when be used for replacing motor 8 to provide passive connecting rod 16 to reset.
Embodiment three
As shown in Figure 3; on embodiment one or two basis; due under abnormal or failure condition; when opening or regain, blade rack 3 all may exceed the extreme position of design; and this situation that goes beyond the limit of the position tends to cause the damage of mechanism; danger is very large; regain caging bolt 14 so be provided with a flabellum in the bottom of blade rack 3; when flabellum 4 is in the extreme position of withdrawal; flabellum is regained caging bolt 14 and can be withstood on base 1, stops blade rack 3 to continue operation and goes beyond the limit of.For similar security consideration, be provided with a limited block 9 on side plate 7, when flabellum 4 was positioned at the extreme position of opening, limited block 9 can withstand passive connecting rod 16, prevented that flabellum 4 from going beyond the limit of the position.
Embodiment four
On embodiment one, two or three basis, opened with hand push easily opening Shi Buhui in order to guarantee subway gate scissors door, as shown in Figure 4 and Figure 5, be provided with an electromagnet sucker 23 on blade rack 3, be provided with an electromagnet 22 on side plate 7, when blade rack 3 is positioned at the position of opening, electromagnet 22 and the 23 phase adhesives of electromagnet sucker.This suction-combining force size can be adjusted by the suction of adjusting electromagnet, and its dynamics size is manually pushed open and can not hindered again the driving of motor 8 to be advisable being not easy.
Above disclosed be only more excellent specific embodiment of the present utility model, still, the utility model is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
