Detailed description of the invention
Should be understood that the upper and lower, left and right in this specification, upwards, downwards, to the left, to the right directional terms be the description for the orientation shown in accompanying drawing, these orientation are not restrictive。Without certain illustrated, term herein is inside, outside, inside and outside, inner side, outside refer to the scope relative to part centre, such as using electrical axis as reference, interior and inner side refers to closer to or points to position or the orientation of electrical axis, refers to further from motor center position with outside outward。Additionally, term level, hold up, the term such as pendency is not offered as requiring parts abswolute level or pendency, and allow to be slightly tilted。As level simply means to its direction opposed vertical level more, it is not represent that this structure is perfectly level, but can be slightly tilted。
As shown in 1～5 figure; it is a kind of escalator of the present utility model or moving sidewalk handrails gateway protection device; it includes gateway rubber parts 1, rotor plate 2, rotates bar 3, back-moving spring 4, fixing base plate 5, switch fixing casing 6, position limitation protection switch 7, switch actuating plate 8 etc.。
It is connected by securing member 22 is fixing between gateway rubber parts 1 with rotor plate 2。On rotor plate 2, coaxial welding has for being socketed a pair nut 21 rotating bar 3。Rotating bar 3 through nut 21 and back-moving spring 4, the end rotating bar is connected fixing by securing member 31 with fixing base plate 5。Such annexation so that gateway rubber parts 1 lever 3 that can rotate rotates, fixing base plate 5 then keeps fixed static constant with connecting rod。
Certainly, nut 21 can also adopt one section of hollow circular-tube to replace, the internal diameter comparable rotation bar 3 big 1～2mm of external diameter of nut or hollow circular-tube。
Fixing base plate 5 is fixed with switch fixing casing 6。Position limitation protection switch 7 is installed on switch fixing casing 6。The plate body of switch fixing casing 6 is provided with vertical groove 62, and the back side of position limitation protection switch 7 is provided with securing member and can slide along described vertical groove about 62 or fixing, in order to make position limitation protection switch be fixed on best operational position。
Switch actuating plate 8 is one piece of bending plate, and it at least has the first plane 82 and the second plane 83, and the first plane and the second plane can be joined directly together, it is also possible to be connected by the 3rd plane being positioned between the two。Approximately fixed angle is kept, so that the rotation of the first plane can cause the rotating in same direction of the second plane between first plane and the second plane。First plane is fixedly connected on gateway rubber parts 1 by securing member 81, and when so that gateway rubber parts 1 rotates, lever 3 rotates, switch actuating plate 8 also can concomitant rotation。The bottom of the second plane 83 is positioned at the top of position limitation protection switch 7, when being in non-toggle state, switchs 7 with position limitation protection and maintain discontiguous gap bottom the second plane 83。When gateway rubber parts is rotated lever rotation by External Force Acting, switch actuating plate 8 also concomitant rotation, now the second plane 83 of switch actuating plate is pressed for 7 times to position limitation protection switch, thus triggering switch protecting circuit, makes staircase shut down。
Back-moving spring 4 is sheathed on outside rotation bar 3, and the first side pressure of back-moving spring 4 is in the surface of fixing base plate 5, and the second end of back-moving spring can directly be pressed on bottom the first plane 82 of switch actuating plate, it is also possible to is pressed on and fixes on the parts being connected with the first plane。By above description it can be seen that the first plane of gateway rubber parts 1, rotor plate 2 and switch actuating plate 8 is fixedly secured to one another synchronous axial system, therefore the second end of back-moving spring can choose to act in three arbitrary among。In this example, it is preferable that act on rotor plate。Under spring prestressing force effect, switch actuating plate is subject to lifting active force, and this lifting active force upwards can make position limitation protection switch switch upwardly away from position limitation protection。When not being subject to External Force Acting, back-moving spring can make switch actuating plate 8 be returned to and switch 7 states being separated with position limitation protection。Therefore; when escalator handrail entrance has foreign body to touch gateway rubber parts 1; the rubber parts lever that rotates in gateway rotates down; position limitation protection switch 7 is touched by 8 times pressures of switch actuating plate and triggers switch protecting circuit and make staircase shut down; and after foreign body is removed; back-moving spring 4 can drive gateway rubber parts to automatically reset by jack-up rotor plate 2, so that escalator or moving sidewalk resume operation。
This utility model includes, but are not limited to above-described embodiment and content shown in the drawings, other all with the technical solution of the utility model, there is the product structure of identical essentiality content and each fall within protection domain of the present utility model。
