Description

TECHNICAL FIELD The present disclosure relates to a truss displacement suppression device for a passenger conveyor.

Conventionally, in order to measure the engagement allowance of the truss to the supporting beam, a measuring rod with a scale is pressed horizontally against the supporting beam, and the length from the supporting beam to the fixed point of the truss is measured by a measuring rod. There is known a method for confirming the displacement of the engagement margin (see, for example, Patent Document 1).

JP 2014-24676 A

However, the conventional passenger conveyor disclosed in Patent Document 1 cannot suppress the displacement of the truss with respect to the receiving beams. Therefore, in the event of an earthquake, for example, even if it is a small earthquake, the truss will be displaced greatly against the supporting beams, and the truss will come into contact with parts such as the floor plate at the entrance and exit, and the parts will be damaged. There is a risk.

A truss displacement suppressing device for a passenger conveyor according to the present disclosure includes a protruding member fixed to the upper surface of a bearing plate fixed to a building portion, and a rod-shaped member connecting a hook member supported by the bearing plate to the protruding member. The hanging member has a fixed portion fixed to the truss body end, which is the longitudinal end of the truss body, and the projecting member faces the fixed portion in the longitudinal direction of the truss body. The rod-shaped member is fixed to the protruding member and the fixed portion in a state in which the fixed portion is separated from the building portion in the longitudinal direction of the truss body.

According to the truss displacement suppression device for a passenger conveyor according to the present disclosure, it is possible to suppress displacement of the truss with respect to the building section.

Thereby, the upper support angle 12 is supported by the bearing plate 51 via a plurality of spacers 52 .

The upper fixed part 121 is arranged apart from each of the bearing plate 51 and the upper building beam 10 in the longitudinal direction of the truss body 11 . In a normal installation state of the escalator, a gap as a truss upper gap exists between each of the upper building beam 10 and the bearing plate 51 and the upper fixed part 121 . In the normal installation state of the escalator, the distance from each of the upper building beam 10 and the bearing plate 51 to the upper fixing portion 121, that is, the dimension of the truss upper gap is the upper gap reference value d1.

The projecting member 71 is fixed to the upper surface of the bearing plate 51 . In this embodiment, the projecting member 71 is a rectangular parallelepiped block. The projecting member 71 is arranged between the lower surface of the horizontal plate portion 122 a and the upper surface of the bearing plate 51 . The projecting member 71 faces the upper fixing portion 121 in the longitudinal direction of the truss body 11 . As a result, the projecting member 71 is arranged apart from the upper fixing portion 121 in the longitudinal direction of the truss body 11 .

The rod-shaped member 72 is fixed to the projecting member 71 and the upper fixing portion 121 in a state in which the upper fixing portion 121 is separated from the upper building beam 10 in the longitudinal direction of the truss body 11 . Thereby, the rod-like member 72 connects the upper fixing portion 121 to the protruding member 71 .

In this embodiment, the rod-like members 72 are arranged horizontally along the longitudinal direction of the truss 1 . Moreover, in the present embodiment, the rod-shaped member 72 is a threaded rod.

As shown in FIG.

The strength of the bar member 72 is smaller than the strength of the truss body 11 . As a result, when excessive force is applied to the rod-shaped member 72 and the truss 1 , the rod-shaped member 72 is more likely to break than the truss 1 . In this embodiment, the compressive strength of the rod-shaped member 72 in the longitudinal direction of the rod-shaped member 72 is smaller than the compressive strength of the truss body 11 in the longitudinal direction of the truss body 11 . Thus, in the present embodiment, when excessive compressive force is applied to the rod-shaped member 72 and the truss 1 , the rod-shaped member 72 is more likely to break than the truss 1 .

3 is an enlarged view showing part III of FIG. 1. FIG. The lower support angle 13 has a lower fixed portion 131 and a lower projecting portion 132 .

The lower fixed part 131 is a plate-like part fixed to the upper part of the end surface of the lower truss body end part 112 . The lower fixing portion 131 is arranged along the end surface of the lower truss body end portion 112 .

The horizontal plate portion 132 a is arranged along the width direction of the truss body 11 . A plurality of reinforcing portions 132b are provided on the lower surface of the horizontal plate portion 132a. The plurality of reinforcing portions 132b are arranged at intervals in the width direction of the truss body 11 .

The lower truss support device 6 has a bearing plate 61 and a plurality of spacers 62 .

A bearing plate 61 is fixed to the upper surface of the lower building beam 20 . In this embodiment, the position of the end face of the bearing plate 61 facing the lower fixed part 131 and the position of the end face of the lower building beam 20 facing the lower fixed part 131 are the same in the longitudinal direction of the truss body 11. It's becoming The position of the end face of the lower building beam 20 facing the lower fixing part 131 may be closer to the lower fixing part 131 than the position of the end face of the bearing plate 61 facing the lower fixing part 131 .

A plurality of spacers 62 are arranged on the upper surface of the bearing plate 61 so as to overlap each other. A plurality of spacers 62 are interposed between the lower surface of the lower projecting portion 132 and the upper surface of the bearing plate 61 . In this embodiment, a plurality of spacers 62 are interposed between the lower surface of each reinforcing portion 132b and the upper surface of the bearing plate 51. As shown in FIG. The lower projecting portion 132 is placed on the bearing plate 61 via a plurality of spacers 62 . Thereby, the lower support angle 13 is supported by the bearing plate 61 via a plurality of spacers 62 .

The lower fixing part 131 is arranged apart from each of the bearing plate 61 and the lower building beam 20 in the longitudinal direction of the truss body 11 . In a normal installation state of the escalator, a gap as a truss lower gap exists between each of the lower building beam 20 and the bearing plate 61 and the lower fixed part 131 . Further, in the normal installation state of the escalator, the distance from each of the lower building beam 20 and the bearing plate 61 to the lower fixed portion 131, that is, the dimension of the truss lower clearance is the lower clearance reference value d2.

No truss displacement suppression device is provided between the lower truss support device 6 and the lower support angle 13 . As a result, the lower support angle 13 can be displaced with respect to the lower truss support device 6 and the lower building beam 20 in the direction in which the dimension of the truss lower gap changes while being supported by the lower truss support device 6 .

Next, operation will be described. When the building in which the escalator is installed shakes due to the occurrence of an earthquake or the like, the horizontal distance between the upper building beam 10 and the lower building beam 20 changes. At this time, since the upper truss support device 5 and the upper support angle 12 are connected by the truss displacement suppression device 7 on the upper floor, the dimension of the truss upper clearance is maintained at the upper clearance reference value d1. On the other hand, on the lower floor, the dimension of the truss lower gap changes from the lower gap reference value d2, and the lower building beam 20 is displaced in the horizontal direction with respect to the truss 1.

FIG. 4 is an enlarged view showing a state in which the lower building beam 20 of FIG. 3 is approaching the lower fixing part 131 from the normal installation state. When a small-scale earthquake or a medium-scale earthquake occurs, the amount of change in the horizontal distance between the upper building beam 10 and the lower building beam 20 is smaller than the lower gap reference value d2 of the truss lower gap. Therefore, even if a small-scale earthquake or a medium-scale earthquake occurs, the gap at the bottom of the truss will not disappear, and the lower building beam 20 will not come into contact with the lower fixing portion 131 . This prevents the truss displacement suppression device 7 and the truss 1 from receiving compressive force from the upper building beam 10 and the lower building beam 20, and prevents the truss displacement suppression device 7 and the truss 1 from being damaged. In FIG. 4, due to the displacement of the lower building beam 20 with respect to the truss 1, the dimension of the truss lower clearance is a value d3 smaller than the lower clearance reference value d2.

On the other hand, when a large-scale earthquake occurs, the amount of change in the horizontal distance between the upper building beam 10 and the lower building beam 20 becomes larger than the lower gap reference value d2 of the truss lower gap. Therefore, the lower building beam 20 contacts the lower fixed part 131 .

5 is an enlarged view showing a state in which the lower building beam 20 of FIG. 4 is in contact with the lower fixing part 131. FIG. When the lower building beam 20 contacts the lower fixed part 131, the truss lower gap disappears. Therefore, in this state, when the lower building beam 20 is further displaced toward the upper building beam 10, the lower fixed part 131 is pushed by the lower building beam 20, and the truss displacement suppressing device 7 and the truss 1 move upward. Compressive force is received from the building beam 10 and the lower building beam 20 .

If the compressive force applied to the truss displacement suppression device 7 and the truss 1 from the upper construction beam 10 and the lower construction beam 20 becomes excessive, the bar member 72 of the truss displacement suppression device 7 will break instead of the truss 1 . When the bar member 72 is damaged, the connection state between the upper support angle 12 and the projecting member 71 is released. This allows the upper building beam 10 to be displaced with respect to the truss 1 . When the upper building beam 10 becomes displaceable with respect to the truss 1, the compressive force applied to the truss 1 is reduced, and the truss 1 is prevented from being damaged. Thus, even if a large-scale earthquake occurs, the truss 1 is prevented from being damaged.

FIG. 6 is an enlarged view showing a state where the bar member 72 of FIG. 2 is broken. When the truss displacement suppressing device 7 receives compressive force, the rod-shaped member 72 receives the compressive force in the longitudinal direction of the rod-shaped member 72 between the upper fixing portion 121 and the projecting member 71 . Therefore, when the rod-shaped member 72 breaks, the rod-shaped member 72 breaks at a position between the upper fixing portion 121 and the projecting member 71 . Thereby, the rod-like member 72 is separated into a first portion 72a fixed to the protruding member 71 and a second portion 72b fixed to the upper fixing portion 121 .

Moreover, when the rod-shaped member 72 is damaged, the rod-shaped member 72 receives a compressive force in the longitudinal direction of the rod-shaped member 72 . Therefore, when the rod-shaped member 72 is separated into the first portion 72a and the second portion 72b, the first portion 72a and the second portion 72b are pushed against each other, and at least the first portion 72a and the second portion 72b are separated. Either bends and deforms plastically. The plastically deformed state of at least one of the first portion 72a and the second portion 72b is maintained even after the earthquake subsides.

After the earthquake subsides, a worker who enters the upper machine room 14 visually checks the state of the bar member 72 through the opening 111b. When the rod-shaped member 72 is damaged, restoration work of the truss displacement suppressing device 7 such as replacement of the rod-shaped member 72 is performed.

In such a truss displacement suppressing device 7 , a projecting member 71 is fixed to the upper surface of the bearing plate 51 fixed to the upper building beam 10 . The rod-shaped member 72 is fixed to the projecting member 71 and the upper fixing portion 121 in a state in which the upper fixing portion 121 is separated from the upper building beam 10 in the longitudinal direction of the truss body 11 . Therefore, the upper building beam 10 and the truss 1 can be connected by the bar member 72 . Thereby, even if an earthquake occurs, displacement of the truss 1 with respect to the upper building beam 10 can be suppressed.

The rod-shaped member 72 is a threaded rod and is fixed to the upper fixing portion 121 and the projecting member 71 by a plurality of nuts 73 attached to the rod-shaped member 72 . Therefore, the work of fixing the bar-like member 72 to each of the upper fixing portion 121 and the projecting member 71 can be facilitated. Further, the fixing positions of the upper fixing portion 121 and the projecting member 71 with respect to the rod-shaped member 72 can be easily adjusted.

Further, the strength of the rod-shaped member 72 is smaller than the strength of the truss body 11 . Therefore, it is possible to make the bar member 72 more susceptible to breakage than the truss 1 . As a result, even if excessive compressive force is applied to the rod-shaped member 72 and the truss 1 in the longitudinal direction due to the occurrence of a large-scale earthquake, it is possible to prevent the truss 1 from being damaged by the damage of the rod-shaped member 72. . Also, the rod-shaped member 72 can be damaged at a position between the projecting member 71 and the upper fixing portion 121 . Therefore, since the projecting member 71 and the upper fixing portion 121 are separated from each other, the broken portion of the rod-shaped member 72 can be exposed between the projecting member 71 and the upper fixing portion 121 .

Here, even if the truss 1 is displaced with respect to the upper building beam 10 during an earthquake, the truss 1 is displaced from the upper building beam 10 by the restoring force of the upper building beam 10 after the earthquake subsides. often returns to its original position. In this way, even if the truss 1 returns to its original position before the earthquake, the damaged portion of the rod-shaped member 72 is exposed between the projecting member 71 and the upper fixed part 121, so that after the earthquake subsides, the rod-shaped member 72 can be restored to its original position. The state of the member 72 can be easily confirmed. Therefore, it is possible to easily determine whether or not the truss 1 has been displaced and whether or not the bar member 72 needs to be replaced. As such, the escalator can be quickly restored after the earthquake subsides.

Further, the upper truss body end portion 111 is provided with an opening 111 b that opens from the upper machine room 14 toward the bar member 72 . Therefore, a worker who enters the upper machine room 14 can easily check the state of the rod-like member 72 visually through the opening 111b. This makes it easier to check the state of the bar member 72, and it is possible to restore the escalator more quickly after the earthquake subsides.

In addition, in the above-described embodiment, the number of truss displacement suppressing devices 7 is two. However, the number of truss displacement suppressing devices 7 may be one, or may be three or more.

Further, in the above embodiment, the rod-shaped member 72 is fixed to each of the upper fixing portion 121 and the protruding member 71 by a plurality of nuts 73 . However, the rod-like member 72 may be fixed to each of the upper fixing portion 121 and the projecting member 71 by welding.

Further, in the above embodiment, the truss displacement suppressing device 7 connects the upper truss support device 5 and the upper support angle 12 on the upper floor. However, the truss displacement suppression device 7 may connect the lower truss support device 6 and the lower support angle 13 on the lower floor. In this case, the projecting member 71 is fixed to the upper surface of the bearing plate 61 of the lower truss support device 6 . Also, in this case, the bar member 72 is fixed to the projecting member 71 and the lower fixing portion 131 in a state in which the lower fixing portion 131 is separated from the lower building beam 20 in the longitudinal direction of the truss body 11 . Furthermore, in this case, the upper truss support device 5 and the upper support angle 12 are not connected by the truss displacement suppression device 7 on the upper floor. Even in this way, the lower building beam 20 and the truss 1 can be connected by the bar member 72, and displacement of the truss 1 with respect to the lower building beam 20 can be suppressed when an earthquake occurs.

Further, when the truss displacement suppressing device 7 connects the lower truss support device 6 and the lower support angle 13 on the lower floor, the opening opened from the lower machine room 15 toward the bar member 72 is the lower truss body end 112 . may be set to In this way, a worker who enters the lower machine room 15 can easily check the state of the bar member 72 visually through the opening of the lower truss body end portion 112 . This makes it easier to check the state of the bar member 72, and it is possible to restore the escalator more quickly after the earthquake subsides.

Further, in the above-described embodiment, the truss displacement suppressing device 7 is applied to an escalator as a passenger conveyor. However, the truss displacement suppressing device 7 may be applied to a moving walkway as a passenger conveyor.
