Abstract
The invention relates to a protective device for preventing an elevator from being opened or closed secondarily. The protective device comprises a guide board, an installation board, an anti-return strip rotationally arranged on the installation board from the middle portion, a guide wheel arranged at one end of the anti-return strip and arranged on the guide board in a rolling manner, an elastic piece with the two ends arranged at the other end of the anti-return strip and the installation board and a limiting column arranged on the anti-return strip and abutting against the right side of the installation board. The guide board comprises a horizontal extending section, a left slope section and a right slope section, wherein the left slope section and the right slope section extend from the horizontal extending section to the left end and the right end respectively. When the guide wheel is located on the horizontal extending section, the limiting column is away from the installation board; when the guide wheel is located on the left slope section or the right slope section, the limiting column prevents a door sliding board from moving rightwards, and the door sliding board is prevented from moving leftwards through the left slope section or the right slope section. Through the adoption of the protective device, the phenomena that a car door is secondarily opened or closed and stopped due to leftward and rightward movement of the door sliding board after a drive mechanism stops working can be effectively prevented, and the operation safety of the car door is guaranteed.

Specifically implement and preferred aspect according to one of the present invention, anti-receipt is parallel with adapter plate and be spaced apart.Prevent anti-receipt from contacting with adapter plate in rotation regulates, and produce noise.
Further, the inner side that elastic reset part one end is connected to the outside of adapter plate, the other end is connected to anti-receipt.It is mainly for elastic reset part plays certain protective effect.
Concrete, elastic reset part is extension spring.
Compared to prior art, tool of the present invention has the following advantages:
The present invention is by the setting of limited post and left and right slope section, and the gate secondary preventing the sway of a slide plate after driver train quits work from causing opens or closes and break, guarantees the safety that gate runs, simultaneously, structure is simple, and it is convenient to implement, and cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the fender guard preventing elevator secondary from opening the door or to close the door of the present invention;
In accompanying drawing: 1, door slide plate; 2, guide plate; 20, horizontal-extending section; 21, left bank section; 22, right bank section; 3, adapter plate; 4, anti-receipt; 5, track adjusting wheel; 6, elastic reset part (extension spring); 7, limited post; 8, guide rail.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
As shown in Figure 1; the present embodiment provides a kind of elevator secondary that prevents to open the door or the fender guard of closing the door, and it comprises and is positioned at the guide plate 2 above a slide plate 1, the adapter plate 3 be fixed on a slide plate 1, rotates the anti-receipt 4 be arranged on adapter plate 3 from middle part, is arranged on an end (left part) of anti-receipt 4 rollably can be arranged on track adjusting wheel 5 on guide plate 2, both ends are separately positioned on anti-receipt 4 the other end (right part) with the elastic reset part 6 on adapter plate 3 and be arranged on the limited post 7 that anti-receipt 4 can be conflicted on the right side of adapter plate 3.
Concrete, guide plate 2 comprises the horizontal-extending section 20 be arranged in parallel with door slide plate 1, the left slope section 21 from bottom to top tilted from the both ends, left and right of horizontal-extending section 20 respectively and right slope section 22.
Further, be convenient to the operation that fender guard is stable, horizontal-extending section 20, left slope section 21 and right slope section 22 are respectively equipped with track 8, and track adjusting wheel 5 is rollably arranged on track 8.
In this example, fender guard has two states, the first be gate normally open or in closed operation now fender guard play directional tagging; The second is that gate is in and opens or closed now fender guard work, limits the sway of door slide plate at the last moment, thus prevent gate open or closed time, the secondary action of industry or break.
Concrete; when fender guard plays directional tagging; track adjusting wheel 5 is positioned at the horizontal-extending section 20 of guide plate 2, and track adjusting wheel 5 is subject to the stress (extruding) of guide plate 2 downwards, and elastic reset part 6 is stretched; anti-receipt 4 rotates counterclockwise; limited post 7 is away from adapter plate 3, and anti-receipt 4 is 10 ~ 30 °, in this example with horizontal-extending section 20 angle; best angle is 15 °, can extend the service life of elastic reset part.
Concrete; when fender guard works; when track adjusting wheel 5 is positioned at left slope section 21 or right slope section 22; track adjusting wheel 5 is not subject to the extruding of guide plate 2, and elastic reset part 6 resets, and anti-receipt 4 rotates clockwise; limited post 7 blocks a slide plate 1 and moves right; meanwhile, track adjusting wheel 5, to left slope section 21 or right slope section 22 application of stress, prevents a slide plate 1 to be moved to the left by left slope section 21 or right slope section 22.Thus realize protection.
Further, the angle of inclination of left slope section 21 or right slope section 22 is identical, and is greater than track adjusting wheel 2 when being positioned at the horizontal-extending section 20 of guide plate 2, the angle of anti-receipt 4 and horizontal-extending section 20.In this example, the angle of inclination is 20 °.Prevent the contact of anti-receipt 4 and left slope section 21 or right slope section 22, affect the smooth operation of fender guard.
Further, adapter plate 3 is fixed on the upper right corner of a slide plate 1.Be convenient to practical operation.
In addition, anti-receipt 4 is parallel with adapter plate 3 and be spaced apart.Prevent anti-receipt 4 from contacting with adapter plate 3 in rotation regulates, and produce noise.
Further, the inner side that elastic reset part 6 one end is connected to the outside of adapter plate 3, the other end is connected to anti-receipt 4.It mainly plays certain protective effect for elastic reset part 6.
Further, the elastic reset part 6 in this example is common extension spring, and the mode that both ends are bolted is connected on adapter plate 3 and anti-receipt 4.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
