Abstract
The utility model provides an anti-collision falling-prevention elevator landing door device which comprises an upper ridge bottom plate, a guide rail and a hanging plate. The hanging plate is installed on the guide rail through an upper hanging wheel and a lower idler wheel in a sliding mode, the upper hanging wheel and the lower idler wheel are arranged on the hanging plate, the upper edge of the rolling surface of the upper hanging wheel is annularly provided with an annular limiting groove in the circumferential direction, the upper portion of the guide rail is provided with an upper convex portion stretching into the annular limiting groove and matched with the annular limiting groove, the lower portion of the guide rail is provided with a horizontally-arranged matching surface, the rolling surface of the lower idler wheel is in sliding fit with the matching surface, one side, close to the hanging plate, of the matching surface is provided with a limiting step convex downwards so as to resist horizontal motion of the lower idler wheel, and the limiting step is located between the lower idler wheel and the hanging plate. Compared with the prior art, the anti-collision falling-prevention elevator landing door device is simple in structure and convenient to manufacture, the hanging plate of the elevator landing door device can be effectively prevented from falling off due to impact, and security of the elevator landing door device is improved.
Description
Technical field
The utility model relates to elevator landing door, especially a kind of elevator landing door of anti-collision and dropping-proof.
Background technology
Bottom roller joint face in upper bank base plate and the link plate of existing elevator landing door is plane, in knockout process link plate be easy to from come off in bank, thereby cause relevant accident.Especially in the time that reply passenger is clashed into, can not guarantee that the roller of layer door gear link plate in knockout process can not deviate from guide rail, thereby layer door can be rushed open in the scope of the power that can apply a people, elevator accident easily occurs.For this situation, need at present the structure of improving upper bank base plate badly, to prevent that link plate from coming off, thereby reduce the accident causing because of door system reason.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of elevator landing door of anti-collision and dropping-proof.
For achieving the above object, the utility model by the following technical solutions:
A kind of elevator landing door of anti-collision and dropping-proof, comprise bank base plate, guide rail and link plate, described link plate is slidably mounted on described guide rail by the upper change gear and the bottom roller that arrange on it, on the rolling surface of described upper change gear, be arranged with annular stop groove along circumferential hoop, the top of described guide rail is provided with stretches into described annular stop groove upper convex portion with matching, it is characterized in that: the bottom of described guide rail is provided with horizontally disposed fitting surface, the rolling surface of described bottom roller and described fitting surface are slidingly fitted, described fitting surface is provided with to lower convexity to keep out the limited step of described bottom roller horizontal motion in the side near described link plate, described limited step is between described bottom roller and described link plate.
Preferably, described limited step is formed by the direct bending of described guide rail.
Preferably, described limited step is welded by stepped plate or screw is fixed on described upper bank base plate.
Owing to adopting technique scheme, the elevator landing door of anti-collision and dropping-proof of the present utility model has improved the structure of upper bank base plate, locate to the bottom roller in link plate by the limited step that is arranged on guide rail bottom, in knockout process, bottom roller is subject to stopping of limited step, thereby prevent that link plate from coming off in knockout process, improved the safety of elevator landing door.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Refer to Fig. 1, an elevator landing door for anti-collision and dropping-proof, comprises bank base plate 1, guide rail 2 and link plate 3, and guide rail 2 is for being horizontally disposed with, link plate 3 is slidably mounted on described guide rail 2 by the upper change gear 4 and the bottom roller 5 that arrange on it, and bottom roller 5 is fixed on link plate 3 by roller mount 6.On the rolling surface of upper change gear 4, be arranged with limited impression 41 along circumferential hoop, the top of guide rail 2 is provided with the upper convex portion 21 that stretches into limited impression 41, and limited impression 41 and upper convex portion 21 match.Wherein, upper bank base plate 1 and guide rail 2 are formed in one, and the upper convex portion 21 of guide rail 2 is formed by upper bank base plate 1 bending.The bottom of guide rail 2 is provided with horizontally disposed fitting surface 22, and the rolling surface of bottom roller 5 and fitting surface 22 are slidingly fitted.The bottom of guide rail 2 is provided with horizontally disposed fitting surface 22, the rolling surface of bottom roller 5 and fitting surface 22 are slidingly fitted, fitting surface 22 is being provided with near a side of link plate 3 to lower convexity to keep out the limited step 23 of bottom roller 5 horizontal motions, and limited step 23 is between bottom roller 5 and link plate 3.
Wherein, limited step 23 can be formed or be welded or screw is fixed on guide rail 2 by stepped plate by the direct bending of guide rail 2.In the present embodiment, the bottom that limited step 23 is welded on guide rail 2 by stepped plate forms.The cross sectional shape of limited impression 41 is arc, and the cross sectional shape of upper convex portion 21 is semicircular arc, and the arc radius of described limited impression 41 is greater than or equal to the arc radius of described upper convex portion 21.
In the present embodiment, between normal bottom roller 5 in service and limited step, there is gap.When clashing into, when shock strength is slighter, the upper convex portion 21 of guide rail 2 and the mating reaction of upper change gear 4 can alleviate to a certain extent impact in knockout process.When shock strength is larger, because bottom roller 5 is owing to being subject to keeping out of limited step 23, the rolling surface of bottom roller 5 all coordinates with fitting surface 22 all the time, thereby has avoided causing the phenomenon that link plate 3 comes off from guide rail 2 to occur because clashing into.Therefore, elevator landing door of the present utility model has the function of anti-collision and dropping-proof, and safety is higher.
