At present, most elevator companies increase a retaining device to meet standard requirements through a reinforced layer door device and a landing sill structure, and obtain certificates through a type test.
At present, the upper part of the upper door in the market is kept and a guide structure mostly adopts a double-roller clamping guide rail, as shown in figure 1, an upper roller 3 and a lower roller 4 are assembled on a hanging door plate 2 to form a hanging door plate assembly. The hanging door plate assembly is arranged on the landing door bottom plate 1, and the lower part in the hanging door plate assembly is used for hoisting the landing door plate 6. As shown in fig. 2, when an external force acts on the landing door panel 6, the lower roller 4 contacts with the arc surface 7 of the guide rail 5, and provides a reverse acting force to keep the hanging door panel 2 at the original position, so as to avoid the falling risk of the landing door panel 6. But two R guide rail processing technology degree of difficulty is big, and the processing equipment requires highly, and in case the clearance between the arc surface 7 of lower gyro wheel 4 and guide rail 5 is slightly bigger, can have the unable contact of arc surface 7 of lower gyro wheel 4 and guide rail 5 or the problem that area of contact is too little, when receiving external force and assaulting, the hanging door board subassembly has the risk of droing.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problems that the lower roller part of the existing landing door adopts a circular arc contact structure to prevent the lower roller from separating from the guide rail, the processing technology of the double-circular arc door head bottom plate is complex, and the precision is not well guaranteed; and the gyro wheel clearance influences anticreep performance down, owing to adopt circular arc contact structure anticreep, slightly bigger as the clearance, gyro wheel under the unable contact of guide rail arc surface, there is the above-mentioned technical problem of risk of droing and provide a new layer door lower roller anticreep structure when external shock, when satisfying the experimental evidence of layer door type, simplify the technology of layer door bottom plate, improve layer door system overhead door plank anticreep performance.
The utility model discloses the technical problem that will solve can realize through following technical scheme:
a novel anti-drop structure for lower rollers of landing doors comprises a landing door bottom plate, a hanging door plate, upper rollers, lower rollers, guide rails and a landing door plate, wherein the upper rollers and the lower rollers are assembled on the hanging door plate to form a hanging door plate assembly, and the lower part of the hanging door plate assembly is used for hoisting the landing door plate; the guide rail is arranged on the landing door bottom plate and is positioned below the landing door bottom plate, a convex circular arc matched with the upper roller is arranged on the guide rail, the upper roller is supported on the convex circular arc in a rolling manner, and the guide rail is provided with a flanging corresponding to the position of the lower roller; the outer peripheral surface of the lower roller consists of a section of cylindrical surface and a section of cylindrical boss, the bottom surface of the flanging is in rolling contact with the cylindrical surface, and the cylindrical boss is positioned on the outer side of the tail end of the flanging.
In a preferred embodiment of the present invention, the bottom surface of the flange is a plane parallel to the axis of the lower roller.
In a preferred embodiment of the present invention, the cylindrical boss radially extends beyond the cylindrical surface.
Since the technical scheme as above is used, the utility model discloses correspond the guide rail the position of gyro wheel down is provided with a turn-ups, and the outer peripheral face of gyro wheel is revised as being constituteed by one section face of cylinder and one section cylinder boss down simultaneously, and the cylinder boss plays the anticreep effect. When the layer door panel receives external force striking, cylinder boss and turn-ups end contact prevent to hang door panel assembly and drop by on the guide rail, improve the security.

Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 3 and 4, the new anti-falling structure for the lower roller of the landing door shown in the figures comprises a landing door bottom plate 1, a hanging door plate 2, an upper roller 3, a lower roller 4a, a guide rail 5a and a landing door plate 6, wherein the upper roller 3 and the lower roller 4a are assembled on the hanging door plate 2 to form a hanging door plate assembly. The lower part of the door hanging plate component is provided with a layer door plate 6 in a hoisting way; the guide rail 5a is arranged on the floor door bottom plate 1 and is positioned below the floor door bottom plate 1, a convex arc 5aa matched with the upper roller 3 is arranged on the guide rail 5a, the upper roller 3 is supported on the convex arc 5aa in a rolling manner, and the floor door panel 6 is hung by the upper roller 3, the convex arc 5aa on the guide rail 5a and the door hanging plate 2.
The utility model is characterized in that: the guide rail 5a is provided with a flange 5ab at a position corresponding to the lower roller 4a, and the bottom surface of the flange 5ab is a plane parallel to the axis of the lower roller 4 a. The peripheral surface of the lower roller 4a consists of a section of cylindrical surface 4aa and a section of cylindrical boss 4ab, and the cylindrical boss 4ab extends out of the cylindrical surface 4aa in the radial direction. The bottom surface of turn-ups 5ab and face of cylinder 4aa rolling contact, and cylinder boss 4ab is located the 5ab terminal outside of turn-ups.
The action principle of the utility model is as follows:
as shown in fig. 3: when external force acts on the landing door panel 6, the hanging door panel assembly can incline, as shown in fig. 4: the terminal contact of the cylindrical boss 4ab of lower gyro wheel 4a and the turn-ups 5ab of guide rail 5a provides counter action power and makes and hang door plant 2 and keep original position, avoids appearing hanging the danger that door plant 2 drops. The diameter of the cylindrical boss 4ab of the lower roller 4a is 6mm larger than that of the cylindrical surface 4aa, so that the falling danger can not occur even if the gap between the cylindrical surface 4aa of the lower roller 4a and the bottom surface of the flange 5ab of the guide rail 5 is increased.
