  In the configuration described in Patent Literature 1-3, the cleaning member attached to the door hanger contacts the upper surface of the door rail and pushes out the foreign matter on the door rail, thereby removing the foreign matter from the movement range of the roller. However, merely pushing out the foreign matter may cause accumulation of foreign matter and prevent the movement of the hanger rail and the door to which the hanger rail is fixed. In particular, when the foreign matter is volcanic ash, the volcanic ash takes in water and oil from the surroundings in a short period of time when left as it is, so the viscosity of the volcanic ash becomes strong and solidifies. As a result, the foreign matter is solidified in a short time, and the movement of the door is restricted, which may cause an open / close failure. In this case, it is necessary for a worker who inspects and repairs the elevator to manually scrape and remove the solidified foreign matter with a tool. Such problems are particularly likely to occur in areas with volcanoes in the vicinity. In addition, volcanic ash floats in a dry state, is easy to enter the building, and is easy to stack on the door rail.

  The object of the door rail cleaning device for elevators according to the present invention is to provide a structure capable of efficiently removing foreign matter such as volcanic ash or the like which is easily solidified in a short period of time on the door rail.

And a cleaning member for moving and cleaning. The door rail is formed by a plurality of door rail elements separated in the longitudinal direction, and a gap is formed between adjacent door rail elements, and the width of the door rail in the longitudinal direction in the gap is the lower end of the door rail The cleaning member is larger than the upper end portion, and when moving on the door rail, the cleaning member removes foreign matter by pushing out the foreign matter and dropping it into the gap. Further, a door rail cleaning device of an elevator according to the present invention is attached to a door rail disposed above the door and a door hanger fixed to an upper end portion of the door, and interlocks with opening and closing of the door. And a cleaning member for moving and cleaning the upper surface, wherein the door rail is formed by a plurality of longitudinally separated door rail elements, a gap is formed between the adjacent door rail elements, and the adjacent door rail elements are The upper end on the gap side of the one door rail element which is separated from the cleaning member when the cleaning member moves closer to the gap is the gap of the other door rail element to which the cleaning member approaches. Higher than the upper end on the side, and the cleaning member pushes out foreign matter when moving on the door rail and falls into the gap Removing the foreign substance by.

  According to the door rail cleaning device of the elevator according to the present invention, the door rail is formed by the plurality of separated door rail elements, and the cleaning member pushes out foreign substances when falling on the door rail and drops it into the gap between the door rail elements. Remove foreign matter. This makes it difficult to accumulate foreign matter, so even if foreign matter such as volcanic ash that easily solidifies in a short period of time is present on the door rail, the foreign matter can be efficiently removed.

  FIG. 1 is a view showing an upper portion of a landing door of an elevator to which a door rail cleaning device 10 of the embodiment is attached. The landing door 50 is a double door type in which the two doors 51 and 52 move so as to open from the center to both sides. The movement of each door 51, 52 is guided by the upper door rail 12 and the lower sill (not shown). A door rail 12 is disposed above the doors 51 and 52, and door hangers 30 and 31 are fixed to upper end portions of the doors 51 and 52, respectively. The door rail 12 forms a door rail cleaning device 10 described later. Further, the doors 51 and 52 are suspended and supported by the door hangers 30 and 31 with respect to the door rail 12. Specifically, the door rail 12 is fixed to a fixing portion 53 such as a wall of the hoistway. The door rail 12 is disposed horizontally along the opening direction on the upper side of the landing doorway. As shown in FIG. 3 to be described later, the cross-sectional shape of the plane orthogonal to the longitudinal direction of the door rail 12 is an oval having upper and lower end portions that are convexly curved.

  On the door hangers 30, 31, two rollers 32 are rotatably supported at portions near both ends in the width direction (left and right direction in FIG. 1) of the doors 51, 52, which is a direction parallel to the moving direction of the doors 51, 52. Mounted as it is. Each roller 32 rolls on the door rail 12 along the longitudinal direction (left and right direction in FIG. 1). Thus, the doors 51 and 52 move in the width direction to open and close the landing doorway.

  The power of an electric motor (not shown) fixed to the fixing portion 53 is transmitted to a drive belt (not shown), and the power of the drive belt is transferred to the door hangers 30, 31 via a connector (not shown). It is transmitted. When the connector connected to one of the two doors 51 and 52 (left side in FIG. 1) moves to one side in the width direction of the door 51, the door 52 on the other (right side in FIG. 1) The coupled coupler moves to the other side in the width direction of the door 52. Thus, the doors 51 and 52 are driven to move in opposite directions in the width direction.

  The door rail cleaning device 10 includes a door rail 12 and cleaning members 13a, 13b, 13c, 13d in which a total of four of the door rails 12 are arranged in correspondence with the respective doors 51, 52. Specifically, the cleaning members 13a, 13b, 13c and 13d are respectively attached to the widthwise outer sides of the corresponding rollers 32 at the widthwise end portions of the doors 51 and 52 from the corresponding rollers 32. And each cleaning member 13a, 13b, 13c, 13d moves and cleans the upper surface of the door rail 12 interlockingly with opening and closing of the doors 51 and 52 so that it may explain in detail below. Hereinafter, the cleaning members 13a, 13b, 13c, and 13d may be collectively referred to as the cleaning member 13.

  Below, the cleaning member 13a attached to the longitudinal direction end part (right end part of FIG. 1) of the door hanger 30 is fundamentally demonstrated about one door 51 among the two doors 51 and 52. As shown in FIG.

  FIG. 2 is an enlarged equivalent view of a portion A in the case where one of the doors 51 of the two doors in FIG. 1 moves to the right in the closing direction from the left side. FIG. 3 is a cross-sectional view taken along line B-B of FIG. FIG. 4 is an enlarged cross-sectional view of a portion A when the doors 51 and 52 have moved in the closing direction.

  The cleaning member 13 a is configured to include the hanger fixing member 14 and the cleaning oil supply member 16 which is a cleaning member main body. The hanger fixing member 14 has a flat plate shape, and two notches 14a opened downward are formed at two longitudinally separated positions on one end side in the longitudinal direction (left side in FIGS. 2 and 4). Then, as shown in FIG. 2, a fastening member such as a bolt inserted through the notch 14a on the outer side in the thickness direction (the front side of the sheet of FIG. 2) at one longitudinal end (right end of FIG. 2) of the door hanger 30. The hanger fixing member 14 is fixed by 15.

  The cleaning oil supply member 16 is fixed to a portion protruding in the longitudinal direction from the tip of the door hanger 30 on the other end side (right side in FIGS. 2 and 4) of the hanger fixing member 14 in the longitudinal direction. The cleaning oiling member 16 is formed in a rectangular parallelepiped shape from a non-woven fabric such as felt impregnated with oil or a foamed resin such as foamed polyurethane. The cleaning fueling member 16 is fixed to the hanger fixing member 14 by a fastening member 17 such as a bolt. With the cleaning oiling member 16 fixed to the hanger fixing member 14, the lower end of the cleaning oiling member 16 away from the hanger fixing member 14 inward in the thickness direction (back side in FIG. 2, paper right in FIG. 3) Is located on the door rail 12. The cleaning oiling member 16 cleans the upper surface of the door rail 12 by moving the upper surface of the door rail 12 in conjunction with the opening and closing of the doors 51 and 52 (FIG. 1) in contact with the upper surface of the door rail 12. Refuel the top of the For example, when volcanic ash adheres to the upper surface of the door rail 12 as the foreign matter 60, the cleaning and fueling member 16 pushes the volcanic ash in the moving direction (the direction of the arrow α in FIG. 2).

  In the above, the cleaning member 13a attached to one longitudinal side (right side in FIG. 2) of the door hanger 30 fixed to one of the two doors 51 and 52 with reference to FIGS. Basically explained. On the other hand, the remaining cleaning members 13b, 13c and 13d among the four cleaning members 13a, 13b, 13c and 13d (FIG. 1) can be configured in the same manner as the cleaning member 13a shown in FIGS. At this time, the cleaning members 13b and 13c attached to the other side (left side in FIG. 1) of the door hangers 30 and 31 fixed to the respective doors 51 and 52 in the longitudinal direction are the cleaning member 13a and the door 51 of FIGS. , 52 in the reverse direction.

  Further, the door rail 12 is formed to include a plurality of door rail elements 12a, 12b, 12c separated in the longitudinal direction (left and right direction in FIGS. 1 and 2). Each door rail element 12 a, 12 b, 12 c is fastened by means of a fastening member 54 such as a bolt to a screw hole 53 a formed in the fixing portion 53. Thereby, each door rail element 12a, 12b, 12c is fixed to the fixing portion 53. In this state, a gap G is formed between the adjacent door rail elements 12a, 12b and 12c. The gap G is used to drop and remove the foreign matter 60 (FIG. 2) as described later. At this time, as shown in FIGS. 1 and 4, two cleaning members 13a disposed between the two door hangers 30 and 31 in the door rail 12 with the doors 51 and 52 completely moved in the closing direction, A gap G is formed in each of the portions facing the cleaning fueling member 16 of 13c.

  FIG. 5 is an enlarged equivalent view of a portion C in FIG. 1 when the doors 51 and 52 (FIG. 1) move in the opening direction (arrow β direction in FIG. 5). As shown in FIG. 5, another door rail element 12d is disposed also on the outside (left side in FIG. 5) of the two door hangers 30 and 31 in the door rail 12 with the doors 51 and 52 completely moved in the opening direction. Be done. Then, a gap G is formed between the door rail elements 12a and 12c (FIG. 1) and the other door rail element 12d. In the gap G, the cleaning oiling members 16 of the two cleaning members 13 b and 13 d (FIG. 1) disposed on the outside of the two door hangers 30 and 31 face. Another door rail element 12 d also forms the door rail 12. 5 shows another door rail element 12d to which the cleaning member 13b attached to the other end (the left end in FIG. 5) of the door hanger 30 in the longitudinal direction of one of the two doors 51 and 52 approaches. ing. The rollers 32 attached to the door hangers 30 and 31 do not face the gap G at the time of movement when the doors 51 and 52 open and close. Thus, the gap G does not prevent the movement of the roller 32.

  When moving on the door rail 12, each cleaning member 13 pushes out the foreign matter 60 which is dust or dust accumulation, and removes the foreign matter 60 by dropping it into the gap G as shown by the arrow γ direction in FIGS. Do.

  According to the above door rail cleaning device 10, the door rail 12 is formed of the plurality of door rail elements 12a, 12b, 12c, 12d, and the cleaning member 13 pushes out the foreign matter 60 when moving on the door rail 12 to between the door rail elements. Drop into gap G. Thereby, the foreign matter is removed. For this reason, since the foreign matter 60 can be made difficult to accumulate, even when there is a foreign matter such as volcanic ash that easily hardens in a short time on the door rail 12, the foreign matter can be efficiently removed. Furthermore, the upper surface of the door rail 12 can be efficiently refueled by the cleaning refueling member 16.

  FIG. 6 is a view corresponding to FIG. 2 showing a door rail cleaning device 10 of another example of the embodiment. In the configuration shown in FIG. 6, in each gap G of the door rail 12, the widths d1 and d2 in the longitudinal direction of the door rail 12 are larger than the width d2 of the upper end portion at the width d1 of the lower end portion of the door rail 12. Furthermore, when the cleaning member 13a is moved so as to approach the gap G among the adjacent door rail elements 12a and 12b, the cleaning member 13a is separated from the one door rail element 12b, and the cleaning member 13a is the other door rail element 12a. Approach and touch. At this time, the upper end T1 on the gap G side of one door rail element 12b is higher than the upper end T2 on the gap G side of the other door rail element 12a.

  Specifically, on the upper surface of the gap G side end of one door rail element 12b, an inclined surface 18 is formed to be inclined upward as the gap G is approached. Thereby, the upper end T1 of one door rail element 12b is higher than the upper end T2 of the other door rail element 12a.

  According to the above configuration, when the cleaning member 13a pushes out the foreign matter 60 and drops it into the gap G, it can be dropped more efficiently by the high end of the one door rail element 12b. As a result, it is possible to prevent the foreign matter 60 from moving to the side of the one door rail element 12b and causing the foreign matter to fly back and reattach to the other door rail element 12a. Further, in each gap G of the door rail 12, the width in the longitudinal direction of the door rail is larger at the lower end portion of the door rail than at the upper end portion. Thus, when the doors 51 and 52 move in the opening and closing direction, the cleaning member 13a can be prevented from projecting inward from the end of the gap G such that the entire lower end surface of the cleaning oiling member 16 faces the upper end opening of the gap G. For this reason, when the cleaning fueling member 16 returns in the reverse direction, it can be efficiently prevented from being caught by the tip of the door rail element 12a, and the widening of the lower end of the gap G can suppress scattering of foreign matter from the gap. The other configurations and functions are similar to the configurations of FIGS. 1 to 5. Although FIG. 6 shows the gap G facing one cleaning member 13a, the gaps facing the remaining cleaning members 13b, 13c and 13d (FIG. 1) can be formed in the same manner.

  Further, the cleaning members attached to the door hangers 30 and 31 are not limited to the cleaning oiling member 16 as in each of the above-described examples, and instead of the cleaning oiling member or together with the cleaning oiling member, the door hanger You may attach the brush which has a hair bundle as. The brush moves the upper surface of the door rail in conjunction with the opening and closing of the door while in contact with the upper surface of the door rail 12 to remove foreign matter.

  In each of the above-mentioned examples, although the cleaning device in the door opening and closing mechanism of the landing has been described, the same configuration can be adopted for the door opening and closing mechanism of the car. In addition, although the cleaning device in the double-open door opening and closing mechanism has been described above, the same configuration can be adopted for the single-open door opening and closing mechanism. Further, the same configuration can be adopted for a door opening and closing mechanism having only one door or three or more doors. Further, the cross-sectional shape of the plane perpendicular to the longitudinal direction of the door rail is not limited to the oval, and may be trapezoidal, rectangular or the like.
