Can be omitted.

Embodiment 1.
FIG. 1 is a configuration diagram of a passenger conveyor 1 according to the first embodiment.

The passenger conveyor 1 is applied to a building. The passenger conveyor 1 is, for example, an escalator that spans between the upper and lower floors of a building. At this time, the passenger conveyor 1 transports passengers between the upper and lower floors. One of the upper floor side and the lower floor side of the passenger conveyor 1 is a departure side where passengers board the passenger conveyor 1. The other of the upper floor side and the lower floor side of the passenger conveyor 1 is the arrival side where passengers get off from the passenger conveyor 1. The passenger conveyor 1 includes a main frame 2, a support device 3, a drive device 4, a plurality of steps 5, a pair of handrails 6, and a control device 7.

The main frame 2 is a portion that supports the structure of the passenger conveyor 1 and is long in the front-rear direction of the passenger conveyor 1. The main frame 2 is, for example, a truss. The main frame 2 is spanned between an upper construction beam 8a provided on the upper floor of the building and a lower construction beam 8b provided on the lower floor of the building. One of the upper construction beam 8a and the lower construction beam 8b is an example of a first construction beam. The other of the upper construction beam 8a and the lower construction beam 8b is an example of a second construction beam. One end of the main frame 2 in the front-rear direction is the end on the upper floor side. The other end of the main frame 2 in the front-rear direction is the end on the lower floor side. The load of the main frame 2 is supported by the support device 3.

The driving device 4 is a device such as a motor that generates driving force. The drive device 4 is arranged, for example, in a machine room provided on the upper floor side of the main frame 2. Each step 5 is a device that circulates and moves by the driving force generated by the driving device 4. Each step 5 moves on an outbound path from the departure side to the arrival side, and moves on a return path below the outbound path from the arrival side to the departure side. The plurality of steps 5 are arranged in a stair-like manner on the outgoing route. Each handrail 6 is a device that circulates and moves by the driving force generated by the driving device 4. Each handrail 6 moves on an outbound path from the departure side to the arrival side, and moves on a return path below the outbound path from the arrival side to the departure side. Each handrail 6 is made of a flexible annular member. One handrail 6 is arranged on the left side of the plurality of steps 5. The other handrail 6 is arranged on the right side of the plurality of steps 5. The control device 7 is a device that controls the operation of the passenger conveyor 1. The control device 7 is arranged, for example, in a machine room provided on the upper floor side of the main frame 2.

During normal operation, the passenger conveyor 1 transports a passenger who is standing on one of the steps 5 while grasping one of the handrails 6, for example, using the driving force generated by the drive device 4 under the control of the control device 7. do. At this time, each step 5 moves in the traveling direction from the departure side to the arrival side on the outbound trip. Each handrail 6 moves cyclically at a moving speed matched to each step 5.

A seismic isolation device (not shown) is applied to a building to which the passenger conveyor 1 is applied. In this example, the seismic isolation device is provided between the lower and upper floors of the building. A seismic isolation device alleviates the transmission of vibration energy due to an earthquake between the lower and upper floors of a building by allowing relative displacement between the lower and upper floors. In this example, the main frame 2 of the passenger conveyor 1 spans between an upper floor provided in the upper layer of a building and a lower floor provided in the lower layer of the building. That is, the seismic isolation device allows relative displacement of the upper building beam 8a and the lower building beam 8b during an earthquake.

FIG. 2 is a diagram showing an example of the arrangement of the support device 3 according to the first embodiment.

The support device 3 is provided at one end of the main frame 2 in the front-rear direction. In this example, the support device 3 is provided at the end of the main frame 2 on the lower floor side. At this time, the upper floor end of the main frame 2 is fixed to the upper building beam 8a. Note that the support device 3 may be provided at the end of the main frame 2 on the upper floor side. Further, the support device 3 may be provided only at one end of the main frame 2 in the front-rear direction, or may be provided at both ends of the main frame 2 in the front-rear direction.

FIG. 3 is a vertical sectional view showing the configuration of the support device 3 according to the first embodiment.
In FIG. 3, a cross section of the support device 3 is shown in a vertical plane including the front and back direction of the passenger conveyor 1.

The support device 3 includes a support angle 9 and a restoring device 10.

The support angle 9 is provided at one end of the main frame 2 in the front-rear direction. In this example, the support angle 9 is attached to the lower end of the main frame 2. The support angle 9 is an angle member having a shape in which the first plate portion 9a and the second plate portion 9b intersect at right angles at their edges, that is, the cross section is L-shaped. The support angle 9 is arranged so that the normal line of the first plate part 9a faces in the front-rear direction, and the normal line of the second plate part 9b faces in the up-down direction. The first plate portion 9a is attached to the lower end of the main frame 2. The second plate portion 9b protrudes to the opposite side of the main frame 2 with respect to the first plate portion 9a, that is, to the outside in the front-rear direction. The lower surface of the second plate portion 9b faces the upper surface of the lower construction beam 8b above the upper surface of the lower construction beam 8b. The second plate portion 9b is an example of a hanging portion of the support device 3. The length of the hanging allowance of the passenger conveyor 1 corresponds, for example, to the length in the front-rear direction of a portion of the second plate portion 9b and the lower construction beam 8b that overlap in the horizontal projection plane.

The restoring device 10 is provided between the lower surface of the second plate portion 9b of the support angle 9 and the upper surface of the lower construction beam 8b. The restoring device 10 generates a restoring force in the direction of returning the relative positions of the second plate part 9b and the lower construction beam 8b to the equilibrium position when the relative positions of the second plate part 9b and the lower construction beam 8b deviate from the equilibrium position. This is a device that allows you to Here, the relative position of the second plate part 9b and the lower construction beam 8b is, for example, the position of the second plate part 9b with respect to the lower construction beam 8b. The equilibrium position is the relative position of the second plate portion 9b and the lower construction beam 8b during normal operation of the passenger conveyor 1. When no earthquake occurs, the relative positions of the second plate portion 9b and the lower construction beam 8b are in an equilibrium position. When the relative positions of the second plate part 9b and the lower construction beam 8b are in the equilibrium position, the length of the hanging allowance of the passenger conveyor 1 is sufficient for the operation of the passenger conveyor 1.

FIG. 4 is an enlarged view of main parts showing the configuration of the support device 3 according to the first embodiment.
In FIG. 4, an enlarged view of portion A shown in broken lines in FIG. 3 is shown.

The restoration device 10 includes a bearing plate 11 and a laminate 12.

The bearing plate 11 is, for example, a flat metal plate. The bearing plate 11 is a part that receives the load of the passenger conveyor 1. The bearing plate 11 is fixedly attached to the upper surface of the lower construction beam 8b.

The laminate 12 is, for example, a laminated rubber bearing. The laminate 12 includes an upper flange 13a, a lower flange 13b, a plurality of metal plates 14, and a plurality of elastic bodies 15. The upper flange 13a is a plate-shaped portion forming the upper surface of the laminate 12. The upper flange 13a is fixedly attached to the lower surface of the second plate portion 9b of the support angle 9. The lower flange 13b is a plate-shaped portion forming the lower surface of the laminate 12. The lower flange 13b is fixedly attached to the upper surface of the lower construction beam 8b. The plurality of metal plates 14 and the plurality of elastic bodies 15 are stacked alternately in the vertical direction between the upper flange 13a and the lower flange 13b. The plurality of metal plates 14 and the plurality of elastic bodies 15 are arranged parallel to each other. Each metal plate 14 is, for example, a disc-shaped steel plate. Each elastic body 15 is, for example, a disc-shaped rubber plate. The side surfaces of the plurality of laminated metal plates 14 and the plurality of elastic bodies 15 may be covered with an elastic body such as a covering rubber.

Next, an example of the function of the support device 3 will be explained using FIG. 5.
FIG. 5 is a diagram showing an example of functions of the support device 3 according to the first embodiment.
FIG. 5 shows an example of the state of the portion shown in FIG. 4 when an earthquake occurs.

When an earthquake occurs, the lower floors of buildings shake due to the earthquake. Seismic isolation devices reduce the transmission of vibrational energy, so the upper floors of the building shake less than the lower floors of the building. In this example, the lower building beam 8b swings with the lower layer of the building. Further, the upper building beam 8a sways less than the lower layer of the building together with the upper layer of the building. Since the upper floor side end of the main frame 2 of the passenger conveyor 1 is fixed to the upper building beam 8a, the main frame 2 of the passenger conveyor 1 swings smaller than the lower floor of the building together with the upper floor of the building. That is, on the lower floor side of the passenger conveyor 1, the lower floor side end of the main frame 2 of the passenger conveyor 1 swings less than the lower construction beam 8b.

Due to such a difference in shaking, the relative positions of the second plate portion 9b of the support angle 9 of the support device 3 provided on the lower floor side of the passenger conveyor 1 and the lower construction beam 8b deviate from the equilibrium position. At this time, the laminate 12 undergoes shear deformation such that each metal plate 14 and each elastic body 15 are displaced parallel to the horizontal direction. Due to the elastic force of the elastic body 15, the laminate 12 generates a restoring force in the direction of returning the relative positions of the second plate portion 9b and the lower construction beam 8b to the equilibrium position. For example, when the elastic body 15 is a linear elastic body, the laminated body 12 generates a stronger restoring force as the deviation from the equilibrium position increases. Note that the elastic body 15 may be a nonlinear elastic body. Since the laminate 12 allows its own shear deformation while generating a restoring force, the relative positions of the second plate portion 9b and the lower construction beam 8b are allowed to fluctuate from the equilibrium position when an earthquake occurs.

As described above, the support device 3 for the passenger conveyor 1 according to the first embodiment includes the support angle 9 including the second plate portion 9b and the restoring device 10. The second plate portion 9b is provided at the end of the main frame 2 on the lower floor side in the front-rear direction. The lower surface of the second plate portion 9b faces the upper surface of the lower construction beam 8b above the upper surface of the lower construction beam 8b. The second plate portion 9b protrudes to the outside of the main frame 2 in the front-rear direction of the main frame 2. The restoration device 10 is provided between the lower surface of the second plate portion 9b and the upper surface of the lower construction beam 8b. The restoring device 10 generates a restoring force in the direction of returning the relative positions of the lower construction beam 8b and the second plate part 9b to the equilibrium position when the relative positions of the lower construction beam 8b and the second plate part 9b deviate from the equilibrium position. let

With such a configuration, when an earthquake occurs, the restoring device 10 allows the relative positions of the second plate portion 9b and the lower construction beam 8b to fluctuate from the equilibrium position while generating a restoring force. Therefore, the transmission of vibrational energy due to the earthquake from the lower floors of the building to the main body of the passenger conveyor 1 is alleviated. That is, the restoration device 10 functions as an isolator. This reduces the possibility of damage to the main body of the passenger conveyor 1. Moreover, since the restoring device 10 generates a restoring force when the relative positions of the second plate part 9b and the lower building beam 8b deviate from the equilibrium position, the relative positions of the second plate part 9b and the lower building beam 8b after an earthquake occur. returns to its equilibrium position. For this reason, shortage of hanging allowance on the lower floor side of the passenger conveyor 1 is less likely to occur. This reduces the possibility that the passenger conveyor 1 will become unusable after an earthquake occurs. Furthermore, since the possibility that restoration work will be required to resolve the shortage of allowances is suppressed, the possibility that maintenance personnel will be dispatched for the restoration work is suppressed. As a result, maintenance personnel will be able to quickly dispatch to the more urgent sites among the sites that require restoration work, which can occur multiple times at the same time when an earthquake occurs.

Furthermore, when the relative positions of the lower construction beam 8b and the second plate portion 9b deviate from the equilibrium position, the restoring device 10 generates a stronger restoring force as the deviation from the equilibrium position increases. As a result, a stronger restoring force acts when the deviation from the equilibrium position is large, making it more difficult for the passenger conveyor 1 to have insufficient coverage on the lower floor side after an earthquake occurs. This further reduces the possibility that the passenger conveyor 1 will become unusable after an earthquake occurs.

Further, the restoration device 10 includes a laminate 12 . The laminate 12 has a structure in which metal plates 14 and elastic bodies 15 are alternately stacked in the vertical direction between the lower surface of the second plate portion 9b and the upper surface of the lower construction beam 8b. The restoring device 10 generates a restoring force using the elastic force of the laminate 12 . Since the restoring force is generated by the elasticity that is the physical property of the elastic body 15 itself of the laminate 12, failure of the support device 3 due to mechanical failure or the like does not occur. Therefore, the restoration device 10 functions more reliably when an earthquake occurs. Furthermore, since high damping rubber or the like can be used as the elastic body 15, the material of the elastic body 15 itself can have a damping function. At this time, the restoration device 10 functions as a damper. Thereby, the restoring device 10 can more effectively suppress the influence of vibration on the main body of the passenger conveyor 1.

Furthermore, the laminate 12 is fixedly attached to the lower surface of the second plate portion 9b. The laminate 12 is fixedly attached to the upper surface of the lower construction beam 8b. Thereby, the laminate 12 generates a restoring force even when the relative positions of the lower construction beam 8b and the second plate part 9b deviate from the equilibrium position in the vertical direction. Therefore, the restoring device 10 can suppress the influence of vibrations caused by the earthquake on the main body of the passenger conveyor 1, regardless of the direction of the shaking caused by the earthquake, whether it is vertical or horizontal. Become.

Moreover, the seismic isolation device provided in the building allows relative displacement of the upper building beam 8a and the lower building beam 8b during an earthquake. The main frame 2 is spanned between the upper construction beam 8a and the lower construction beam 8b. Since the relative displacement of the upper construction beam 8a and the lower construction beam 8b due to an earthquake is absorbed by the support device 3, the possibility of damage to the passenger conveyor 1 is suppressed.

Note that the passenger conveyor 1 may be an inclined moving walkway in which steps 5 are arranged in the form of a slope on the outward journey.

Embodiment 2.
In Embodiment 2, points that are different from the example disclosed in Embodiment 1 will be explained in particular detail. As for the features not described in the second embodiment, any of the features in the examples disclosed in the first embodiment may be adopted.

FIG. 6 is an enlarged view of main parts showing the configuration of the support device 3 according to the second embodiment.
In FIG. 6, a cross section of the support device 3 taken along a vertical plane including the front-rear direction of the passenger conveyor 1 is shown.

The restoration device 10 includes a bearing plate 11, a tray 16, a holder 17, and a sphere 18.

The tray 16 is mounted on the bearing plate 11 so as to be fixed to the upper surface of the lower construction beam 8b. The saucer 16 has a concave surface 16a facing upward. The concave surface 16a of the tray 16 slopes downward toward the center. The concave surface 16a of the tray 16 is isotropically inclined in the horizontal direction. The concave surface 16a of the saucer 16 is a curved surface that slopes more toward the center. The shape of the concave surface 16a of the receiving tray 16 is, for example, the surface shape of a rotating body whose axis of rotation is the vertical direction. The shape of the concave surface 16a of the saucer 16 may be, for example, a portion of a spherical surface such as a spherical crown, a portion of a spheroidal surface, or a portion of another rotating body surface. The distance from the center to the outer periphery of the concave surface 16a of the receiving tray 16 is, for example, the radius of the concave surface 16a in the horizontal direction. For example, when the concave surface 16a of the saucer 16 is a spherical crown, the distance from the center of the concave surface 16a of the saucer 16 to the outer periphery is the radius of the bottom of the spherical crown.

The holder 17 is a device that holds the sphere 18. The retainer 17 is attached to the second plate part 9b of the support angle 9 so as to be fixed to the lower surface of the second plate part 9b. The retainer 17 is, for example, a ball bearing. The holder 17 holds the sphere 18 so that it does not move in the horizontal direction with respect to the lower surface of the second plate portion 9b. The holder 17 rotatably holds the sphere 18. That is, the cage 17 does not restrict the rotation of the sphere 18.

The sphere 18 is, for example, a metal sphere. The sphere 18 receives the load of the passenger conveyor 1 from the lower surface of the second plate portion 9b of the support angle 9 via the holder 17. The sphere 18 is placed on the concave surface 16a of the saucer 16. The curvature of the surface of the sphere 18 is determined by the radius of the sphere 18. The curvature of the surface of the sphere 18 is greater than the curvature at the center of the concave surface 16a of the saucer 16. The radius of the sphere 18 is shorter than the distance from the center to the outer periphery of the concave surface 16a of the receiving tray 16. The sphere 18 is provided so that it can roll on the concave surface 16a of the tray 16 while being held by the holder 17.

The restoring device 10 sets the relative position where the sphere 18 is above the center of the concave surface 16a of the receiving tray 16 as the equilibrium position of the relative positions of the second plate part 9b and the lower construction beam 8b. When the relative positions of the second plate portion 9b and the lower construction beam 8b deviate from the equilibrium position, the sphere 18 rolls and moves to a portion that slopes downward toward the center of the concave surface 16a of the receiving tray 16. At this time, the restoring device 10 uses gravity to generate a restoring force that returns the relative positions of the second plate portion 9b and the lower construction beam 8b to the equilibrium position.

The restoring device 10 sets the relative position where the sphere 18 is above the center of the concave surface 16a of the receiving tray 16 as the equilibrium position of the relative positions of the second plate part 9b and the lower construction beam 8b. Due to the difference in shaking between the lower and upper floors of the building when an earthquake occurs, the relative positions of the second plate portion 9b of the support angle 9 of the support device 3 provided on the lower floor side of the passenger conveyor 1 and the lower construction beam 8b are at the equilibrium position. deviate from At this time, the sphere 18 rolls and moves to a portion that slopes downward toward the center of the concave surface 16a of the receiving tray 16. Thereby, the restoring device 10 generates a restoring force using gravity to return the relative positions of the second plate portion 9b and the lower construction beam 8b to the equilibrium position. The magnitude of the restoring force is determined by the inclination of the concave surface 16a at the portion where the sphere 18 has moved. For example, when the concave surface 16a of the receiving tray 16 is more inclined as the distance from the center increases, the restoring device 10 generates a stronger restoring force as the deviation from the equilibrium position increases.

As explained above, the restoring device 10 of the support device 3 of the passenger conveyor 1 according to the second embodiment includes the receiving tray 16 and the sphere 18. The tray 16 is fixedly attached to the upper surface of the lower construction beam 8b. The tray 16 has a concave surface 16a that slopes downward toward the center. The sphere 18 is provided so as not to move horizontally with respect to the lower surface of the second plate portion 9b of the support angle 9, but to be able to roll on the concave surface 16a of the receiving tray 16. The sphere 18 receives a load from the lower surface of the second plate portion 9b. The restoring device 10 takes the relative position where the sphere 18 is above the center of the concave surface 16a of the receiving tray 16 as an equilibrium position. The restoring device 10 uses gravity to generate a restoring force that returns the relative positions of the second plate portion 9b and the lower construction beam 8b to an equilibrium position.

With such a configuration, when an earthquake occurs, the restoring device 10 passively generates a restoring force while allowing the relative positions of the second plate portion 9b and the lower building beam 8b to fluctuate from the equilibrium position. This reduces the possibility of damage to the main body of the passenger conveyor 1. Moreover, since the restoring device 10 generates a restoring force when the relative positions of the second plate part 9b and the lower building beam 8b deviate from the equilibrium position, the relative positions of the second plate part 9b and the lower building beam 8b after an earthquake occur. returns to its equilibrium position. For this reason, shortage of hanging allowance on the lower floor side of the passenger conveyor 1 is less likely to occur. This reduces the possibility that the passenger conveyor 1 will become unusable after an earthquake occurs.

Further, the concave surface 16a of the receiving tray 16 is isotropically inclined in the horizontal direction. Thereby, the restoring device 10 can suppress the influence of vibrations caused by the earthquake on the main body of the passenger conveyor 1, regardless of the direction of the horizontal seismic motion.

Further, the concave surface 16a of the receiving tray 16 is a curved surface that slopes more and more as the distance from the center increases. As a result, a stronger restoring force acts when the deviation from the equilibrium position is large, making it more difficult for the passenger conveyor 1 to have insufficient coverage on the lower floor side after an earthquake occurs. This further reduces the possibility that the passenger conveyor 1 will become unusable after an earthquake occurs.

Further, the curvature at the center of the concave surface 16a of the receiving tray 16 is smaller than the curvature of the surface of the sphere 18. The distance from the center to the outer circumference of the concave surface 16a of the receiving tray 16 is greater than the radius of the sphere 18. This allows the sphere 18 to roll smoothly on the concave surface 16a. Therefore, when an earthquake occurs, the restoring force by the restoring device 10 is more reliably generated.

To summarize the above description, possible configurations of the technology according to the present disclosure include each configuration shown as an additional note below.
