Description

    The present invention relates to a passenger conveyor and a passenger conveyor device including an escalator and an electric road provided with a guide fence in the vicinity of an entrance / exit, and more particularly to a support structure for a passenger conveyor to a building cradle.

  2. Description of the Related Art Conventionally, a support structure for a main body frame of a passenger conveyor has a support portion such as L-shaped steel (also referred to as a truss support angle) provided at an end of the main body frame (truss) mounted on a cradle (also referred to as a receiving beam) on the building side. The height of the building floor is adjusted so that the floor of the passenger conveyor is the same with jack bolts provided on the support of the main body frame. FIG. 6 is a diagram showing a general schematic configuration of the passenger conveyor, and shows a related structure of the truss 1, the balustrade 15, the building 3, and the truss support angle 2. 7 and 8 show a conventional support structure of the truss 1, and are a view from the side and a view from the entrance / exit.

  The truss support angle 2 is provided with a truss support bolt 4 that can be adjusted in the height direction. When the passenger conveyor is installed in the building, the truss support bolt 4 is used to adjust the height and horizontal level of the truss support angle 2. Yes. The overlapping length B of the truss support angle 2 and the building cradle 7 is a length formed by the end of the truss support angle 2 and the end of the building 3. The passenger conveyor cradle 7 of the building 3 is provided with an iron plate 8 on its upper surface (the iron plate 8 stabilizes the support more than the concrete on the surface of the cradle), and this iron plate 8 is the tip of the truss support bolt 4. It is in contact with the part. In the following description, it is described that the passenger conveyor via the truss support angle 2 is not supported by the iron plate 8 but is supported by the cradle 7 in a broad sense.

  In order to make the passenger conveyor floor surface height indicated by the symbol F in FIG. 7 the same as the floor surface height of the building, it is necessary to adjust the height with the truss support bolts 4, and the height shown in FIG. It is necessary to ensure the amount of change H. Here, when a change occurs in the relative position of the passenger conveyor and the building 3 (position in the longitudinal direction of the passenger conveyor) due to the influence of earthquake motion, the truss support bolt 4 shown in FIG. If the position is shifted by half of the length B, the tip of the truss support bolt 4 is disengaged from the cradle 7 and the passenger conveyor floor surface height F is the amount of change H in the truss support bolt height H. Will only change low.

  In order to prevent the passenger conveyor floor height F from decreasing stepwise due to the effects of earthquake motion, etc., interposing a plate-like support and a height adjusting liner between the truss support angle and the cradle, For example, Patent Documents 1 and 2 disclose conventional techniques. According to Patent Document 1, it is disclosed that a liner is inserted into a gap formed by adjusting the height of the jack bolt, the jack bolt is removed, and the passenger conveyor is supported by the liner. Also, according to Patent Document 2, when a level adjustment spacer is interposed between the base plate and the support portion angle, and relative displacement in the longitudinal direction of the passenger conveyor occurs, the support portion angle is contacted to prevent movement. Providing a clasp portion to be disclosed is disclosed.

  However, in the technique described in Patent Document 1 above, the length of the liner inserted in the gap formed by adjusting the height of the jack bolt in the longitudinal direction of the passenger conveyor is not particularly specified, and the jack bolt is not installed after installation. Due to the removal, the building on which the passenger conveyor is installed shakes greatly due to the effect of large earthquake motion, causing longitudinal displacement between the passenger conveyor and the building. There is concern that the installation height of the surface will change.

  In the technique described in Patent Document 2, a three-stage sliding support member having a length exceeding the overlapping portion is interposed between the base plate and the support portion angle. It is multi-layered and complicated, and the sliding motion when earthquake motion occurs is not simple. Moreover, the clasp part which prevents the movement of the passenger conveyor at the time of an earthquake motion describes the displacement of the passenger conveyor in the longitudinal direction, and does not consider the displacement movement of the passenger conveyor in the width direction.

  In the present invention, when the relative position between the passenger conveyor and the building or the civil engineering structure changes due to the influence of earthquake motion or the like, the floor position of the passenger conveyor entrance is not lowered due to the relative position change in the longitudinal direction of the passenger conveyor. In addition, an object of the present invention is to provide a passenger conveyor in which a relative position change in the width direction of the passenger conveyor is prevented by a movement blocking member having a simple configuration.

To solve the above SL technical problems, first means of the present invention, a truss for supporting and fixing the balustrade with handrail, a step of circulating traveling provided floor beds to the truss, the said truss building A truss support angle supported by a cradle and provided at an end of the truss, and a plate-like support for supporting the truss on the cradle, the truss support angle The plate-like support is moved in the passenger conveyor width direction provided in the cradle when the relative position in the passenger conveyor width direction changes between the building and the passenger conveyor. The movement restricting member is in contact with a restricting member, and the movement restricting member is installed in a space between the cradle of the building and the truss support angle .

  According to the present invention, the floor position of the passenger conveyor entrance / exit can be prevented from descending due to seismic motion or the like, so that it is not necessary to perform restoration work for readjustment of the passenger conveyor floor height after seismic motion or the like. Can do.

  Further, movement restriction / blocking in the width direction of the passenger conveyor can be implemented with a simple configuration, and the movement restriction member can be reduced in size by being disposed opposite the plate-like support.

FIG. 6 is a diagram illustrating a general schematic configuration of a passenger conveyor, and is a side view illustrating a related structure of a truss, a railing, a building, and a truss support angle.

  In the drawing, the passenger conveyor includes a balustrade 15 having a handrail, a truss 1 (also referred to as a support frame or a main body frame) on which the balustrade 15 is installed, a step 16 provided in the truss 1 and circulating between floors; And a truss support angle 2 provided at the end of the truss that supports the truss 1 on the building 3 (building or civil engineering structure). The passenger conveyor is placed endlessly and places passengers on the circulating step 16. Step 16 is connected by a chain (not shown) and travels on a forward-side step guide rail and a return-side step guide rail (not shown). Step 16 is driven by a passenger conveyor driving device (not shown).

  The truss support angles 2 are provided at both ends of the passenger conveyor in the longitudinal direction, and are supported by the truss support bolts 4 on the iron plate 8 of the cradle 7 of the building 3. And installed on the cradle 7 of the building 3.

  Here, a passenger conveyor including a truss 1 (support frame or main body frame), a balustrade 15, a truss support angle 2, a plate-like support 5 described later, a cradle 7 of a building 3 that supports the passenger conveyor, and a later-described The entire passenger conveyor support mechanism including the movement restriction member 10 in the passenger conveyor width direction is referred to as a passenger conveyor device.

  FIG. 1 and FIG. 2 are basic configuration examples relating to the passenger conveyor support structure according to the present embodiment, and a plate-like shape of the passenger conveyor is provided between the truss support angle 2 and the iron plate 8 on the cradle 7 of the building 3. A support 5 and a height adjusting liner 6 for adjusting the passenger conveyor floor surface height F are interposed. Here, the iron plate 8 has a concrete rugged surface smoothed by an iron plate 8 or the like instead of concrete with the surface of the building cradle 7 being exposed. Basically, the truss 1 is connected via the truss support angle 2. It is supported by the cradle 7. Therefore, not only the iron plate 8 but also any material may be used as long as the plate-like support 5 is supported by surface contact. The height adjusting liner 6 may be a stack of a plurality of liners to ensure an appropriate height, or may be replaced with a liner having a different thickness to ensure an appropriate height. The height adjusting liner 6 is not necessarily an essential element as long as the height can be secured by the plate-like support 5.

  According to the conventional structure shown in FIG. 7, when the seismic motion is shifted by half the length B of the truss support angle 2 and the cradle 7, the truss support bolt 4 is detached from the cradle 7 and the passenger conveyor has a height H However, if the plate-like support body 5 and the adjustment liner 6 shown in FIG. It will not descend.

  FIG. 3 is a view showing another basic configuration example related to the support structure of the passenger conveyor according to the present embodiment, in which the length in the longitudinal direction of the passenger conveyor of the plate-like support body 5 is set to B or more as shown in D. Yes (D> B). With the structure having the length of D, even if the seismic motion is vibration exceeding B, if the vibration strength D is not exceeded as expected, the passenger conveyor descends and no step is generated from the building floor.

  The relationship between the screws of the truss support bolt 4 and the screw holes of the plate-like support 5 and the height adjusting liner 6 will be described. The screw holes of the truss support angle 2 through which the truss support bolt 4 passes and the adjustment liner 6 may be so-called fool holes, and the holes of the plate-like support 5 are threaded holes. By doing in this way, a passenger conveyor can be installed in the building stand 7 in the state which hold | maintained the plate-shaped support body 5 to the truss support angle 2 with the truss support bolt 4. FIG. The adjustment liner 6 may be a long hole in the surface direction having an open end on one side so that it can be inserted between the plate-like support 5 and the truss support angle 2 during the installation operation.

  Note that the tip of the truss support bolt 4 does not protrude from the plate-like support 5 so that the lower surface of the plate-like support 5 comes into surface contact with the cradle 7. Moreover, what is necessary is just to fix the height by tightening the nut which the truss support bolt 4 shows in figure when the height of each floor surface of a passenger conveyor and a building corresponds. Further, FIG. 2 shows a situation in which the width direction movement restriction member 10 in the passenger conveyor according to the present embodiment is in contact with the plate-like support body 5. The movement restriction member 10 will be described below.

  Next, the movement limitation of the passenger conveyor in the passenger conveyor width direction according to the embodiment of the present invention will be described with reference to FIG. ) And will be described below with reference to FIGS. FIG. 4 is a front view showing the structure and arrangement of the width direction movement restricting member related to the passenger conveyor according to the embodiment of the present invention as viewed from the entrance / exit side, and FIG. 5 is the width direction movement related to the passenger conveyor according to the embodiment of the present invention. FIG. 9 is a plan view showing the structure and arrangement of the restricting member, and FIG. 9 is a front view of the structure and arrangement of the passenger conveyor width direction movement restricting member as seen from the entrance / exit side.

  During the earthquake motion, the relative displacement between the passenger conveyor and the building occurs not only in the longitudinal direction of the passenger conveyor shown in FIG. 1 (left and right in FIG. 1) but also in the width direction of the passenger conveyor shown in FIG. 4 (left and right in FIG. 4). To do. Here, with respect to relative displacement in the width direction of the passenger conveyor, as a movement limiting member of the passenger conveyor, a movement limiting member 11 is conventionally provided on the cradle 7 facing the truss support angle 2 with reference to FIG. It was. According to FIG. 9, the horizontal portion of the truss support angle 4 through which the truss support bolt 4 is inserted comes into contact with the movement limiting member 11, and the height of the movement limiting member 11 is higher than the horizontal portion of the truss support angle 4. Must be at least as high as possible (in the example of FIG. 9, twice the height of the horizontal portion). The collision moment of the horizontal portion of the truss support angle 4 horizontally moved by the relative displacement during the earthquake motion to the movement restricting member 11 is the product of the height from the cradle 7 and the collision force of the horizontal portion.

  The passenger conveyor width direction movement restricting member according to the embodiment of the present invention is a member 10 that contacts the plate-like support 5 as shown in FIGS. 4 and 5. Since the plate-like support body 5 is screwed by the plurality of truss support bolts 4, the movement of the passenger conveyor is restricted and prevented by the width direction movement restricting member 10 without causing a positional shift. In FIG. 4, the movement restricting member 10 is provided on the cradle 7 or the iron plate 8 on the left side in the width direction of the passenger conveyor. It is designed to limit the movement of the left and right sides of the direction.

  As shown in FIG. 5, the height H2 of the width direction movement limiting member 10 can be made lower than the height H1 of the plate-like support 5 and the adjustment liner, and the width direction movement limiting member 10 can support the truss. It can be installed in the gap between the horizontal portion of the angle 4 and the cradle 7 (or the iron plate 8 on the cradle 7), and the width dimension of the passenger conveyor can be reduced in comparison with the conventional example of FIG. . Further, the collision moment applied to the width direction movement restricting member 10 is smaller as the applied height is lower as compared with the conventional example of FIG.

  As described above, the present invention has been described using the embodiment. However, the configuration described in each of the embodiments so far is merely an example, and the present invention can be appropriately changed without departing from the technical idea thereof. It is.
