Description
Technical Field
The present invention relates to a passenger conveyor provided with a truss.
Background
As for the passenger conveyor, there is an escalator provided between an upper floor and a lower floor of a building. One end of the truss of the escalator described in patent document 1 is fixed to a building by a fixing pin. Further, the other end of the truss of the escalator is slidably supported with respect to the building. That is, one of the support points of the truss of the escalator is a fixed support structure. In addition, the other support point is a slidable support structure.
If an earthquake occurs, the building is rocked, and relative movement occurs between one bearing point and another. At this time, when the displacement amount between the one support point and the other support point is a certain amount or less, the other end of the truss slides with respect to the building, and an excessive compressive force is not applied to the truss. In addition, when the displacement between one support point and the other support point is a certain amount or more, the fixing pins for fixing the truss and the building are broken. This enables the 1 st truss end of the truss to move relative to the building without applying an excessive compressive force to the truss.

Problems to be solved by the invention
However, in the conventional escalator described in patent document 1, the fixing pins are broken by a large sway. The truss, which loses its fixing point, moves relative to the building due to the sway. That is, the truss is displaced by the earthquake. Therefore, a restoring operation of lifting the truss by a crane and returning the truss to the position at the time of installation is required.
The present invention has been made to solve the above problems. Specifically, the present invention aims to provide a passenger conveyor that does not require a restoration operation even if there is a large shake.
Means for solving the problems
The passenger conveyor of the present invention comprises: a truss provided between a 1 st fixing part and a 2 nd fixing part of the building, and having a 1 st truss end part and a 2 nd truss end part; a 1 st support device which is provided at the 1 st fixing section and supports the 1 st truss end section; and a 2 nd supporting device which is provided at the 2 nd fixing part and supports the 2 nd truss end part, wherein the 1 st supporting device can be switched between a 1 st holding state in which the 1 st fixing part and the 1 st truss end part do not move relatively and a 1 st release state in which the 1 st fixing part and the 1 st truss end part can move relatively in the horizontal direction, the 2 nd supporting device can be switched between a 2 nd holding state in which the 2 nd fixing part and the 2 nd truss end part do not move relatively and a 2 nd release state in which the 2 nd fixing part and the 2 nd truss end part can move relatively in the horizontal direction, and the passenger conveyor generates at least any one of the 1 st holding state of the 1 st supporting device and the 2 nd holding state of the 2 nd supporting device.
Effects of the invention
In the passenger conveyor of the present invention, at least either one of the 1 st holding state of the 1 st supporting device and the 2 nd holding state of the 2 nd supporting device is generated. That is, regardless of the sway, at least one of the 1 st support device and the 2 nd support device always holds the truss to the building. Therefore, in the passenger conveyor according to the present invention, it is not necessary to perform the restoration operation after the building sways.

Detailed Description
A passenger conveyor, i.e., an escalator, according to embodiment 1 of the present invention will be described.
Fig. 1 is a schematic view of a building 1 provided with an escalator 2. In this example, the escalator 2 is disposed across an upper floor 10 of 3 floors and a lower floor 11 of 2 floors in the building 1. The direction in which the building tilts when the sway occurs is defined as the positive direction with respect to the right direction in fig. 1.
Fig. 2 is a schematic view showing an arrangement state of the escalator 2 of fig. 1. The upper floor 10 is provided with a 1 st fixing portion 12R. The 2 nd fixing portion 12L is provided on the lower floor 11. The 1 st fixing section 12R is located higher than the 2 nd fixing section 12L and is horizontally spaced from the 2 nd fixing section 12L.
In a state where the building 1 is not swayed, the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is larger than a reference distance described later. When the building 1 shakes due to an earthquake, the 1 st fixing section 12R and the 2 nd fixing section 12L move relatively. Therefore, the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L changes. The amount of change in the horizontal distance varies depending on the size of the earthquake and the structure of the building 1. In the present description, when the building 1 shakes and the horizontal distance between the 1 st fixing unit 12R and the 2 nd fixing unit 12L changes, a small shaking state in which both the upper limit value and the lower limit value of the horizontal distance fall within a range equal to or greater than the reference distance is defined as the 1 st shaking state, and a shaking state in which the change in the horizontal distance is so large that the upper limit value of the horizontal distance is greater than the reference distance and the lower limit value of the horizontal distance is smaller than the reference distance is defined as the 2 nd shaking state.
The escalator 2 includes a truss 3, and a 1 st supporting device 4R and a 2 nd supporting device 4L that support the truss 3.
The truss 3 is formed by combining a plurality of steel beams. Further, truss 3 has a 1 st truss end 31R at one end of truss 3 and a 2 nd truss end 31L at the other end of truss 3.
The 1 st supporting device 4R is provided to the 1 st fixing portion 12R. Furthermore, the 1 st support means 4R supports the 1 st truss end 31R of the truss 3. Thereby, the 1 st truss end 31R of the truss 3 is supported by the 1 st fixing part 12R via the 1 st supporting device 4R.
The 2 nd supporting device 4L is provided to the 2 nd fixing portion 12L. Furthermore, the 2 nd support device 4L supports the 2 nd truss end 31L of the truss 3. Thereby, the 2 nd truss end 31L of the truss 3 is supported by the 2 nd fixing part 12L via the 2 nd supporting device 4L.
Fig. 3 is a side view showing the 1 st supporting device 4R of fig. 2. Fig. 4 is an enlarged view of a portion a in fig. 3.
As shown in fig. 3, the 1 st support 32R is an angle steel having an L-shaped cross section. The 1 st support 32R includes a vertical connection 321R and a horizontal connection 322R. The 1 st support 32R has an L-shaped cross-section formed by the vertical connecting portion 321R and the horizontal connecting portion 322R.
The vertical connecting portion 321R is fixed to the 1 st end surface 311R of the 1 st truss end portion 31R. The horizontal connecting portion 322R extends from the upper end of the vertical connecting portion 321R toward the 1 st fixing portion 12R.
The 1 st supporting device 4R includes a 1 st fitting member 41R, a 1 st receiving member 42R, and a 1 st elastic deformation member 43R.
The 1 st receiving member 42R is fixed to the 1 st fixing portion 12R. The 1 st receiving member 42R is a plate-like member having a top surface 421R. The horizontal connecting portion 322R of the 1 st support 32R is slidably mounted on the top surface 421R of the 1 st receiving member 42R. A 1 st gap 13R is provided in the horizontal direction between the vertical connecting portion 321R of the 1 st support 32R and the 1 st fixing surface 121R of the 1 st fixing portion 12R. The size of the 1 st gap 13R is set to a sufficient size so that the vertical connecting portion 321R does not contact the 1 st end surface 311R even in the 2 nd wobbling state.
The 1 st groove portion 422R into which the 1 st fitting member 41R is fitted is formed in the top surface portion 421R of the 1 st receiving member 42R. The sectional shape of the 1 st groove portion 422R viewed in the side view direction of the truss 3 is a right triangle including the groove perpendicular surface portion 423R and the groove inclined surface portion 424R. The groove vertical surface portion 423R is vertical to the top surface portion 421R. Groove inclined surface portion 424R is inclined with respect to top surface portion 421R. The groove vertical surface portion 423R is located on the 1 st truss end 31R side with respect to the groove inclined surface portion 424R. The distance between the groove vertical surface portion 423R and the groove inclined surface portion 424R, that is, the width of the 1 st groove portion 422R is narrower toward the lower side than the opening width of the 1 st groove portion 422R.
The 1 st fitting part 41R includes a projection vertical surface portion 411R and a projection inclined surface portion 412R. The section of the 1 st fitting part 41R in the side view of the escalator 2 is a right triangle. Projection vertical surface 411R is located on the 1 st truss end 31R side with respect to projection inclined surface 412R. In a state where the 1 st fitting member 41R is fitted to the 1 st groove portion 422R, the projection vertical surface portion 411R is vertical to the top surface portion 421R of the 1 st receiving member 42R, and the projection inclined surface portion 412R is inclined with respect to the top surface portion 421R of the 1 st receiving member 42R.
The 1 st elastically deforming member 43R is a plate spring. One end of the 1 st elastically deforming member 43R is fixed to the horizontal connecting portion 322R of the 1 st support member 32R. The other end of the 1 st elastic deformation member 43R is provided with a 1 st fitting member 41R formed separately from the 1 st elastic deformation member 43R. The 1 st elastically deforming member 43R and the 1 st fitting member 41R may be formed integrally.
The 1 st fitting member 41R and the 1 st groove portion 422R are fitted in a state where the protrusion vertical surface portion 411R and the groove vertical surface portion 423R are in contact and the protrusion inclined surface portion 412R and the groove inclined surface portion 424R are in contact. In a state where the 1 st fitting member 41R is fitted to the 1 st groove portion 422R, the 1 st gap 13R is generated. The 1 st fitting member 41R and the 1 st receiving member 42R are fitted in a state where the 1 st elastic deformation member 43R is not elastically deformed. The 1 st elastically deforming member 43R elastically deforms by the 1 st fitting member 41R sliding along the groove inclined surface portion 424R in a direction to come off the 1 st groove portion 422R. Thereby, the 1 st elastically deforming member 43R generates an elastic restoring force against the force in the direction in which the 1 st fitting member 41R is disengaged from the 1 st groove portion 422R. That is, the 1 st elastically deforming member 43R biases the 1 st fitting member 41R by an elastic restoring force so that the 1 st fitting member 41R is fitted to the 1 st groove portion 422R. When the 1 st fitting member 41R is not fitted to or removed from the 1 st groove portion 422R, the 1 st elastically deforming member 43R biases the 1 st fitting member 41R in a direction in which the 1 st fitting member 41R is pressed against the top surface portion 421R.
By fitting the 1 st fitting member 41R to the 1 st groove portion 422R, the 1 st supporting device 4R holds the 1 st fixing portion 12R and the 1 st truss end portion 31R so as not to move relative to each other. This state is the 1 st hold state. Further, by the 1 st fitting member 41R being disengaged from the 1 st groove portion 422R, the 1 st supporting device 4R releases the 1 st fixing portion 12R and the 1 st truss end portion 31R so as to be relatively movable in the horizontal direction. This state is the 1 st release state. The 1 st supporting device 4R can switch from the 1 st holding state to the 1 st releasing state and from the 1 st releasing state to the 1 st holding state.
Fig. 5 is a side view showing the 2 nd supporting device 4L of fig. 2. Fig. 6 is an enlarged view of a portion B in fig. 5.
As shown in fig. 5, the 2 nd support 32L is an angle steel having an L-shaped cross section. The 2 nd support 32L includes a vertical connection 321L and a horizontal connection 322L. The cross-sectional shape of the 2 nd support 32L is formed into an L-shape by the vertical connecting portion 321L and the horizontal connecting portion 322L.
The vertical connecting portion 321L is fixed to the 2 nd end surface 311L of the 2 nd truss end portion 31L. The horizontal connecting portion 322L extends from the upper end of the vertical connecting portion 321L toward the 2 nd fixing portion 12L.
The 2 nd supporting device 4L includes a 2 nd fitting member 41L, a 2 nd receiving member 42L, and a 2 nd elastic deformation member 43L.
The 2 nd receiving member 42L is fixed to the 2 nd fixing portion 12L. The 2 nd receiving member 42L is a plate-like member having a top surface 421L. The horizontal connecting portion 322L of the 2 nd support member 32L is slidably placed on the top surface 421L of the 2 nd receiving member 42L. A 2 nd gap 13L is provided in the horizontal direction between the vertical connecting portion 321L of the 2 nd support 32L and the 2 nd fixing surface 121L of the 2 nd fixing portion 12L. The size of the 2 nd gap 13L is set to a size that the lower connecting portion 321L contacts the 2 nd end surface 311L in the 2 nd wobbling state.
A 2 nd groove 422L into which the 2 nd fitting member 41L is fitted is formed in the top surface 421L of the 2 nd receiving member 42L. The sectional shape of the 2 nd groove portion 422L viewed in the side view direction of the truss 3 is a right triangle including the groove vertical surface portion 423L and the groove inclined surface portion 424L. The groove vertical surface portion 423L is vertical to the top surface portion 421L. Groove inclined surface portion 424L is inclined with respect to top surface portion 421L. The groove-inclined surface portion 424L is located on the 2 nd truss end 31L side with respect to the groove vertical surface portion 423L. The distance between the groove vertical surface portion 423L and the groove inclined surface portion 424L, that is, the width of the 2 nd groove portion 422L is narrower toward the lower side than the opening width of the 2 nd groove portion 422L.
The 2 nd fitting part 41L includes a projection vertical surface portion 411L and a projection inclined surface portion 412L. The section of the 2 nd fitting part 41L in the side view of the escalator 2 is a right triangle. Protrusion inclined surface portion 412L is located on the 2 nd truss end 31L side with respect to protrusion vertical surface portion 411L. In a state where the 2 nd fitting member 41L is fitted to the 2 nd groove portion 422L, the projection vertical surface portion 411L is vertical to the top surface portion 421L of the 2 nd receiving member 42L, and the projection inclined surface portion 412L is inclined with respect to the top surface portion 421L of the 2 nd receiving member 42L.
The 2 nd elastically deforming member 43L is a plate spring. One end of the 2 nd elastically deforming member 43L is fixed to the horizontal connecting portion 322L of the 2 nd support member 32L. The other end of the 2 nd elastically deforming member 43L is provided with a 2 nd fitting member 41L formed separately from the 2 nd elastically deforming member 43L. The 2 nd elastically deforming member 43L and the 2 nd fitting member 41L may be formed integrally.
The 2 nd fitting member 41L and the 2 nd groove portion 422L are fitted in a state where the projection vertical surface portion 411L is in contact with the groove vertical surface portion 423L and the projection inclined surface portion 412L is in contact with the groove inclined surface portion 424L. The 2 nd fitting member 41L and the 2 nd receiving member 42L are fitted in a state where the 2 nd elastically deforming member 43L is not elastically deformed. The 2 nd elastically deforming member 43L elastically deforms by the 2 nd fitting member 41L sliding along the groove inclined surface portion 424L in a direction to come off the 2 nd groove portion 422L. Thereby, the 2 nd elastically deforming member 43L generates an elastic restoring force against the force in the direction in which the 2 nd fitting member 41L is disengaged from the 2 nd groove portion 422L. That is, the 2 nd elastically deforming member 43L urges the 2 nd fitting member 41L by an elastic restoring force so that the 2 nd fitting member 41L is fitted to the 2 nd groove portion 422L. When the 2 nd fitting member 41L is not fitted to or removed from the 2 nd groove portion 422L, the 2 nd elastically deforming member 43L biases the 2 nd fitting member 41L in a direction in which the 2 nd fitting member 41L is pressed against the top surface portion 421L.
In a state where the 2 nd fitting member 41L is fitted to the 2 nd groove portion 422L, the 2 nd truss end portion 31L is in contact with the 2 nd fixing portion 12L. When the truss 3 is installed, the 2 nd fitting member 41L is detached from the 2 nd groove 422L, and the 2 nd gap 13L is generated between the 2 nd truss end 31L and the 2 nd fixing portion 12L.
By fitting the 2 nd fitting member 41L to the 2 nd groove 422L, the 2 nd supporting device 4L holds the 2 nd fixing portion 12L and the 2 nd truss end 31L so as not to move relative to each other. This state is the 2 nd holding state. Further, by the 2 nd fitting member 41L being disengaged from the 2 nd groove portion 422L, the 2 nd supporting device 4L releases the 2 nd fixing portion 12L and the 2 nd truss end portion 31L so as to be relatively movable in the horizontal direction. This state is the 2 nd release state. The 2 nd supporting device 4L can perform two kinds of switching from the 2 nd holding state to the 2 nd releasing state and from the 2 nd releasing state to the 2 nd holding state.
When the truss 3 is installed and in the 1 st rocking state, the 2 nd fitting member 41L is detached from the 2 nd groove portion 422L. That is, when the truss 3 is installed and in the 1 st rocking state, the 2 nd supporting device 4L is in the 2 nd released state in which the 2 nd truss end 31L of the truss 3 is slidable with respect to the 2 nd fixing portion 12L. Therefore, in the 1 st rocking state, the horizontal connecting portion 322L of the 2 nd bearing member 32L slides on the top surface portion 421L of the 2 nd receiving member 42L.
The reference distance between the 1 st fixing portion 12R and the 2 nd fixing portion 12L is a horizontal distance between the 1 st fixing portion 12R and the 2 nd fixing portion 12L in a state where the 1 st fitting member 41R is fitted to the 1 st groove portion 422R and the 2 nd fitting member 41L is fitted to the 2 nd groove portion 422L. In other words, the reference distance is a distance obtained by subtracting the interval of the 2 nd gap 13L provided when the truss 3 is provided from the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L when the truss 3 is provided.
Fig. 7 is a side view showing the 1 st supporting device 4R in which the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L of fig. 2 is smaller than the reference distance. Fig. 8 is a side view showing the 2 nd supporting device 4L in which the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L in fig. 2 is smaller than the reference distance. At the time of installation and in the 1 st rocking state, the 1 st supporting device 4R is in the 1 st holding state, and the 2 nd supporting device 4L is in the 2 nd releasing state. Therefore, the 2 nd truss end portion 31L can move relative to the 2 nd fixing portion 12L. The 1 st truss end 31R held in the building 1 also swings together with the building 1 as the building 1 swings. Therefore, the 2 nd truss end 31L not held in the building 1 approaches the 2 nd fixing part 12L while swinging. Finally, the 2 nd truss end 31L is in contact with the 2 nd fixing portion 12L. As shown in fig. 8, the 2 nd fitting member 41L is fitted into the 2 nd groove 422L of the 2 nd receiving member 42L at the time when the 2 nd truss end 31L comes into contact with the 2 nd fixing portion 12L. That is, the 2 nd supporting device 4L is in the 2 nd holding state. When the 2 nd supporting device 4L is in the 2 nd holding state, the 2 nd truss end 31L and the 2 nd fixing portion 12L cannot move relative to each other.
After the 2 nd truss end 31L comes into contact with the 2 nd fixing section 12L and the 2 nd support device 4L is in the 2 nd holding state, the 2 nd truss end 31L and the 2 nd fixing section 12L are moved relatively in the direction to further approach each other by continuing the rocking. Therefore, a horizontal load acts between the protrusion vertical surface 411L of the 2 nd fitting member 41L and the groove vertical surface 423L of the 2 nd receiving member 42L in a direction to approach each other. As a result, the protrusion vertical surface 411L presses the groove vertical surface 423L. Since the protrusion vertical surface portion 411L and the groove vertical surface portion 423L are both vertical surfaces, no sliding occurs between the surfaces of the protrusion vertical surface portion 411L and the groove vertical surface portion 423L. Therefore, a horizontal load, in which the protrusion vertical surface 411L presses the groove vertical surface 423L, acts on the truss 3. That is, the motion of the building 1 shaking acts on the 2 nd truss end 31L as a horizontal load via the 2 nd truss end 31L and the 2 nd fixing portion 12L that move integrally. As a result of which the girder 3 is pressed.
When the truss 3 is pressed, a horizontal load acts between the projection inclined surface portion 412R of the 1 st fitting member 41R and the groove inclined surface portion 424R of the 1 st receiving member 42R in the 1 st supporting device 4R in a direction to bring them closer to each other. The protrusion inclined surface portion 412R and the groove inclined surface portion 424R are inclined surfaces. Therefore, the protrusion inclined surface portion 412R relatively moves so as to slide up the groove inclined surface portion 424R by the horizontal load acting between the protrusion inclined surface portion 412R and the groove inclined surface portion 424R. As a result, the 1 st fitting member 41R is disengaged from the 1 st groove portion 422R of the 1 st receiving member 42R. Therefore, the 1 st truss end 31R can move relative to the 1 st fixing portion 12R.
Even if a horizontal load acts in a direction to bring the protrusion vertical surface 411L and the groove vertical surface 423L closer to each other, that is, between the vertical surfaces, the fitting between the 2 nd fitting member 41L and the 2 nd groove portion 422L does not become disengaged. The 2 nd supporting device 4L maintains the 2 nd holding state. Further, when a horizontal load acts between the protrusion inclined surface portion 412R and the groove inclined surface portion 424R, that is, between the inclined surfaces in a direction to bring the inclined surfaces closer to each other, the fitting between the 1 st fitting member 41R and the 1 st groove portion 422R is released. As a result, the 1 st supporting device 4R is changed from the 1 st holding state to the 1 st releasing state.
In the 2 nd rocking state where the rocking is larger than the 1 st rocking state, the 2 nd supporting device 4L is switched from the 2 nd releasing state to the 2 nd holding state in the process of the rocking of the building 1. Further, while the 2 nd supporting device 4L is switched from the 2 nd releasing state to the 2 nd holding state, the 1 st supporting device 4R is switched from the 1 st holding state to the 1 st releasing state. That is, in the 2 nd rocking state, the device holding the truss 3 is switched from the 2 nd supporting device 4L to the 1 st supporting device 4R.
The 1 st supporting device 4R and the 2 nd supporting device 4L operate as follows with respect to the variation of the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L. When the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is the reference distance, the 1 st supporting device 4R is in the 1 st holding state, and the 2 nd supporting device 4L is in the 2 nd holding state. Further, when the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is larger than the reference distance, the 1 st supporting device 4R is in the 1 st holding state, and the 2 nd supporting device 4L is in the 2 nd releasing state. Further, when the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is smaller than the reference distance, the 1 st supporting device 4R is in the 1 st released state, and the 2 nd supporting device 4L is in the 2 nd held state.
The horizontal load when the 1 st supporting device 4R is switched from the 1 st holding state to the 1 st releasing state is as follows. The horizontal load at which the 1 st support device 4R is switched to the 1 st released state is larger than the horizontal load determined by both the horizontal inertial force of the truss 3 acting on the truss 3 when the building 1 sways and the frictional force between the 2 nd truss end 31L of the truss 3 and the 2 nd support device 4L, and is smaller than the compressive strength of the truss 3. In addition, the horizontal load when the 1 st supporting device 4R is switched from the 1 st holding state to the 1 st releasing state acts on the truss 3 as a compressive load.
Further, the horizontal load when the 2 nd supporting device 4L is switched from the 2 nd holding state to the 2 nd releasing state is as follows. The horizontal load at which the 2 nd support device 4L is switched to the 2 nd release state is larger than the horizontal load determined by both the horizontal inertial force of the truss 3 acting on the truss 3 when the building 1 sways and the frictional force between the 1 st truss end 31R and the 1 st support device 4R, and is smaller than the breaking strength of the 1 st support device 4R. In addition, the horizontal load when the 2 nd supporting device 4L is switched from the 2 nd holding state to the 2 nd releasing state acts on the truss 3 as the tensile load.
Next, a relationship between the sway of the building 1 at the time of the earthquake and the motions of the 1 st supporting device 4R and the 2 nd supporting device 4L with respect to the sway will be described. Fig. 9 is a conceptual diagram illustrating a relationship between the sway of the building 1 and the operation of each of the 1 st support device 4R and the 2 nd support device 4L. In fig. 9 (a) to 9 (H), for easy understanding, the position of the 2 nd fixing portion 12L is fixed in each drawing.
Fig. 9 (a) shows a state when the truss 3 is set. When the truss 3 is installed, the 1 st supporting device 4R is in the 1 st holding state, and the 2 nd supporting device 4L is in the 2 nd releasing state.
Fig. 9 (B) shows the 1 st support device 4R and the 2 nd support device 4L when the building 1 is inclined in the positive direction in the 1 st sway state. Fig. 9 (C) shows the 1 st support device 4R and the 2 nd support device 4L when the building 1 is inclined in the negative direction in the 1 st sway state. When the building 1 is inclined in the positive direction in the 1 st sway state, as shown in fig. 9 (B), the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is longer than that when the truss 3 is installed. Thereby, the 1 st supporting device 4R maintains the 1 st holding state, the 2 nd supporting device 4L maintains the 2 nd releasing state, and the truss 3 moves in the positive direction with respect to the 2 nd fixing portion 12L. At this time, the 2 nd truss end 31L slides with respect to the 2 nd receiving member 42L. As a result, the 2 nd gap 13L between the vertical connecting portion 321L of the 2 nd support member 32L and the 2 nd fixing surface 121L of the 2 nd fixing portion 12L is widened.
Thereafter, when the building 1 is inclined in the negative direction, as shown in fig. 9 (C), the 1 st supporting device 4R maintains the 1 st holding state, the 2 nd supporting device 4L maintains the 2 nd releasing state, and the truss 3 moves in the negative direction. At this time, the 2 nd truss end 31L slides with respect to the 2 nd receiving member 42L, and the 2 nd gap 13L is narrowed. That is, the horizontal distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is narrower than when the truss 3 is provided.
That is, in the 1 st rocking state, the 1 st supporting device 4R maintains the 1 st holding state, the 2 nd supporting device 4L maintains the 2 nd releasing state, and the states of fig. 9 (B) and 9 (C) are repeated. Then, the shaking finally converges.
Fig. 9 (D) to 9 (H) show the relationship between the sway of the building 1 in the 2 nd sway state and the respective states of the 1 st supporting device 4R and the 2 nd supporting device 4L. When the state of rocking of the building 1 is the 2 nd rocking state, the building 1 rocks more greatly than in the 1 st rocking state. As shown in fig. 9 (D), in the 2 nd sway state, if the building 1 is inclined in the positive direction, the horizontal distance between the 1 st fixing section 12R and the 2 nd fixing section 12L is wider than the horizontal distance when the truss 3 is installed. At this time, the 1 st supporting device 4R maintains the 1 st holding state, the 2 nd supporting device 4L maintains the 2 nd releasing state, and the truss 3 moves in the forward direction. Therefore, the 2 nd truss end 31L side slides with respect to the 2 nd receiving member 42L. As a result, the 2 nd gap 13L between the vertical connecting portion 321L of the 2 nd supporter 32L and the 2 nd fixing surface 121L is wider than that in fig. 9 (B) in the 1 st rocking state. The length of the 2 nd receiving member 42L to which the vertical connecting portion 321L is joined is a sufficient length that the girder 3 does not fall off even when the shaking reaches the maximum. Therefore, the lap margin at which the vertical connecting portion 321L laps over the 2 nd receiving member 42L is sufficiently secured, and even if the rocking occurs, the girder 3 is always supported by the building 1.
Fig. 9 (E) shows a state immediately after fig. 9 (D). When the building 1 is inclined in the negative direction, the horizontal distance between the 1 st fixing section 12R and the 2 nd fixing section 12L is narrowed. At this time, the 1 st supporting device 4R maintains the 1 st holding state, the 2 nd supporting device 4L maintains the 2 nd releasing state, and the truss 3 moves in the negative direction. Therefore, the 2 nd truss end 31L slides with respect to the 2 nd receiving member 42L. The 2 nd gap 13L between the vertical connection part 321L of the 2 nd supporter 32L and the 2 nd fixing surface 121L disappears, and the vertical connection part 321L contacts the 2 nd fixing surface 121L. That is, the horizontal distance between the 1 st fixing section 12R and the 2 nd fixing section 12L becomes the reference distance. At this time, the 2 nd supporting device 4L is switched from the 2 nd releasing state to the 2 nd holding state. That is, the 1 st supporting device 4R is kept in the 1 st holding state, and the 2 nd supporting device 4L is brought into the 2 nd holding state. Thereby, the movement of the 2 nd fixing part 12L caused by the shaking is transmitted to the truss 3. As a result, a horizontal load acts on the truss 3 from the 2 nd fixing portion 12L via the 2 nd supporting device 4L. Therefore, a horizontal load starts to be applied to the 1 st supporting device 4R via the truss 3.
Fig. 9 (F) shows a state immediately after fig. 9 (E). As the building 1 is further inclined in the negative direction, the horizontal load applied to the truss 3 is larger than the state of fig. 9 (E). While the 1 st supporting device 4R is in the 1 st holding state, the horizontal load acting on the truss 3 acts on the truss 3 as a compressive load. When the horizontal load acting on the truss 3 reaches the switching load for switching the 1 st supporting device 4R to the 1 st released state, the 1 st supporting device 4R is switched from the 1 st retained state to the 1 st released state before the compressive strength load of the truss 3 is reached. Thereafter, when building 1 is further inclined in the negative direction due to continuous sway, truss 3 further moves with respect to 1 st fixing portion 12R, and 1 st truss end portion 31R slides with respect to 1 st receiving member 42R. Therefore, the horizontal distance between the 1 st fixing portion 12R and the 2 nd fixing portion 12L is further narrowed than the state of fig. 9 (E), and the 1 st gap 13R between the vertical connecting portion 321R and the 1 st fixing surface 121R is narrowed. When the 1 st supporting device 4R is switched to the 1 st release state, the 1 st truss end 31R slides with respect to the 1 st fixing portion 12R, and thus the compressive load acting on the truss 3 is sharply reduced.
Fig. 9 (G) shows a state immediately after fig. 9 (F). With respect to fig. 9 (F), the building 1 is in a state of starting to sway in the opposite direction. When the building 1 starts to sway in the positive direction after swaying in the negative direction, the 1 st truss end 31R slides in the positive direction, and the 1 st gap 13R expands. Thereafter, the 1 st fitting member 41R reaches the 1 st groove portion 422R, and the 1 st fitting member 41R is fitted to the 1 st groove portion 422R. That is, the 1 st supporting device 4R is switched from the 1 st releasing state to the 1 st holding state.
Fig. 9 (H) shows a state in which the sway of the building 1 converges from the state of fig. 9 (G). The building 1 returns to the installation state by further swinging in the forward direction from the state of fig. 9 (G). At this time, the 1 st support device 4R is kept in the holding state, the 2 nd support device 4L is kept in the holding state, and the truss 3 moves in the forward direction. Therefore, the 2 nd fitting member 41L is disengaged from the 2 nd groove portion 422L. That is, the 1 st supporting device 4R is returned to the 2 nd released state, which is the same as when the truss 3 is provided. As a result, the 2 nd truss end 31L slides with respect to the 2 nd receiving member 42L. By the building 1 returning to the set state, the 2 nd gap 13L becomes wider as compared with the state of fig. 9 (G). That is, the distance between the 1 st fixing part 12R and the 2 nd fixing part 12L is wider than the state of fig. 9 (G). The position of the truss 3 with respect to the building 1, the state of the 1 st supporting device 4R, and the state of the 2 nd supporting device 4L are returned to the states at the time of installation.
In the escalator 2 according to embodiment 1 of the present invention, the 1 st supporting device 4R is switchable between the 1 st holding state and the 1 st releasing state, and the 2 nd supporting device 4L is switchable between the 2 nd holding state and the 2 nd releasing state. Even if the building 1 shakes and the states of the 1 st support device 4R and the 2 nd support device 4L are switched, at least either of the 1 st holding state of the 1 st support device 4R and the 2 nd holding state of the 2 nd support device 4L occurs in the escalator 2. That is, at least either one of the 1 st support device 4R and the 2 nd support device 4L always keeps the truss 3 and the building 1 in a state of not moving relative to each other. Therefore, even if building 1 shakes and truss 3 moves relative to building 1, the position of truss 3 can be maintained relative to at least one of first fixing unit 12R and second fixing unit 12L. Therefore, when building 1 shakes, truss 3 can be prevented from being displaced simultaneously with respect to both of first fixing unit 12R and second fixing unit 12L. Thus, even when the building 1 is shaken, the positions of the escalator 2 with respect to the 1 st fixing section 12R and the 2 nd fixing section 12L can be automatically returned to the original positions, and the restoration work of the escalator 2 is not required.
Further, the magnitude of the horizontal load required for switching from the 1 st holding state to the 1 st releasing state and switching from the 2 nd holding state to the 2 nd releasing state is a load smaller than the compressive strength of the truss 3. Therefore, the horizontal load of the compressive strength or more can be prevented from being applied to the truss 3. As a result, the truss 3 can be prevented from being damaged.
Fig. 10 is a side view showing the 1 st supporting device 5R in the 1 st rocking state. Fig. 10 is a diagram corresponding to fig. 3 in embodiment 1. Fig. 11 is an enlarged view of a portion C in fig. 10. Fig. 11 is a diagram corresponding to fig. 4 in embodiment 1.
A 1 st holding member 54R is fixed to one end of the horizontal connecting portion 322R of the 1 st support 32R. The 1 st holding member 54R is a bottomed cylindrical member. The 1 st holding member 54R is fixed to the horizontal connecting portion 322R with the opening facing downward.
The 1 st elastically deforming member 53R is a coil spring. The 1 st elastically deforming member 53R is housed in the 1 st holding member 54R. One end of the 1 st elastically deforming member 53R is fixed to the bottom portion of the 1 st holding member 54R on the inside of the bottomed cylinder. Further, a 1 st fitting member 41R is fixed to the other end of the 1 st elastically deforming member 53R. The shape and the mounting direction of the 1 st fitting member 41R are the same as those in embodiment 1. The 1 st fitting part 41R includes a projection vertical surface portion 411R and a projection inclined surface portion 412R, and is attached so that a tapered portion formed by the projection vertical surface portion 411R and the projection inclined surface portion 412R faces downward.
The 1 st elastically deforming member 53R and the 1 st fitting member 41R are attached in this manner, whereby the 1 st elastically deforming member 53R biases the 1 st fitting member 41R toward the top surface portion 421R of the 1 st receiving member 42R perpendicularly to the top surface portion 421R. The conditions and actions of the switching operation between the 1 st holding state and the 1 st releasing state of the 1 st supporting device 5R are the same as those in embodiment 1 in which the 1 st elastically deforming member 53R is a plate spring.
Fig. 12 is a side view showing the 2 nd supporting device 5L in the 1 st rocking state. Fig. 12 is a diagram corresponding to fig. 5 in embodiment 1. Fig. 13 is an enlarged view of a portion D in fig. 12. Fig. 13 is a diagram corresponding to fig. 6 in embodiment 1.
A 2 nd holding member 54L is fixed to one end of the horizontal connecting portion 322L of the 2 nd support 32L. The 2 nd holding member 54L is a bottomed cylindrical member. The 2 nd holding member 54L is fixed to the horizontal connecting portion 322L with the opening facing downward.
The 2 nd elastically deforming member 53L is a coil spring. The 2 nd elastically deforming member 53L is housed in the 2 nd holding member 54L. One end of the 2 nd elastically deforming member 53L is fixed to the bottom of the 2 nd holding member 54L inside the bottomed cylinder. Further, a 2 nd fitting member 41L is fixed to the other end of the 2 nd elastically deforming member 53L. The shape and the mounting direction of the 2 nd fitting member 41L are the same as those in embodiment 1. The 2 nd fitting part 41L includes a projection vertical surface portion 411L and a projection inclined surface portion 412L, and is attached so that a tapered portion formed by the projection vertical surface portion 411L and the projection inclined surface portion 412L faces downward.
The 2 nd elastically deforming member 53L and the 2 nd fitting member 41L are attached in this manner, whereby the 2 nd elastically deforming member 53L biases the 2 nd fitting member 41L toward the top surface portion 421L of the 2 nd receiving member 42L so as to be perpendicular to the top surface portion 421L. The conditions and actions of the switching operation between the 2 nd holding state and the 2 nd releasing state of the 2 nd supporting device 5L are the same as those in embodiment 1 in which the 2 nd elastically deforming member 53L is a plate spring.
Fig. 14 is a side view showing the 1 st supporting device 5R of fig. 10 in a 2 nd rocking state. Fig. 15 is a side view showing the 2 nd supporting device 5L of fig. 12 in the 2 nd rocking state. The conditions and actions of the switching operation between the 1 st holding state and the 1 st releasing state of the 1 st supporting device 5R in the 2 nd rocking state are the same as those in embodiment 1 in which the 1 st elastically deforming member 53R is a plate spring. Similarly, the conditions and actions of the switching operation between the 2 nd holding state and the 2 nd releasing state of the 2 nd supporting device 5L in the 2 nd rocking state are the same as those in embodiment 1 in which the 2 nd elastically deforming member 53L is a plate spring.
The 1 st elastic deformation member 53R and the 2 nd elastic deformation member 53L in embodiment 2 of the present invention are formed as coil springs. Therefore, the operation direction of the 1 st fitting part 41R and the 2 nd fitting part 41L can be set to be perpendicular to the top surfaces 421R and 421L. This can shorten the length of the 1 st support device 5R and the 2 nd support device 5L in the horizontal direction of the horizontal connection portions 322R and 322L, that is, in the horizontal direction. Further, since the coil spring can form a spring stroke longer than that of the plate spring, the 1 st elastic deformation member 53R and the 2 nd elastic deformation member 53L can have spring characteristics optimal for the state switching operation of the 1 st supporting device 5R and the 2 nd supporting device 5L. For example, the 1 st elastic deformation member 53R and the 2 nd elastic deformation member 53L can have spring characteristics that expand and contract gently with respect to displacement, as compared with the 1 st elastic deformation member 43R and the 2 nd elastic deformation member 43L formed of the plate spring in embodiment 1.
Embodiment 3.
Embodiment 3 of the present invention differs from embodiment 1 in the structure for bringing the 1 st support device 6R and the 2 nd support device 6L into the holding state. In embodiment 1, the 1 st supporting device 4R and the 2 nd supporting device 4L are held by fitting of members to each other, whereas in embodiment 3, the holding state is achieved by attraction between magnets. The embodiment is the same as embodiment 1 except for the portions that change with respect to the modification. In the following description, the same reference numerals are used for the same members as those in embodiment 1.
Fig. 16 is a side view showing the 1 st supporting device 6R in the 1 st rocking state. Fig. 16 is a diagram corresponding to fig. 3 in embodiment 1.
The 1 st supporting device 6R includes a 1 st magnet device 64R, a 1 st receiving member 62R, and a 1 st holding member 63R. The 1 st receiving member 62R is a plate-like member fixed to the 1 st fixing portion 12R. The horizontal connecting portion 322R of the 1 st support 32R is slidably mounted on the top surface portion of the 1 st receiving member 62R.
The 1 st holding member 63R is a rod-like member such as: one end portion thereof is fixed to the horizontal connecting portion 322R of the 1 st support member 32R, and the rod-like member extends in the horizontal direction in a direction away from the 1 st support member 32R. A short right-angled portion bent downward at a right angle is formed at the other end portion of the 1 st holding member 63R.
The 1 st magnet device 64R includes a 1 st fixing portion side magnet 65R and a 1 st truss end portion side magnet 66R. The 1 st fixing portion side magnet 65R is fixed to the top surface portion of the 1 st receiving member 62R. The 1 st truss end portion side magnet 66R is fixed to a right-angled portion formed at the other end portion of the 1 st holding member 63R. Therefore, the 1 st truss end portion side magnet 66R moves in accordance with the movement of the 1 st truss end portion 31R.
The mounting position of the 1 st fixing portion side magnet 65R on the 1 st receiving member 62R is determined as follows. First, the truss 3 is provided so that the 1 st gap 13R is provided between the vertical connecting portion 321R of the 1 st support 32R and the 1 st fixing surface 121R of the 1 st fixing portion 12R. The size of the 1 st gap 13R is such that the lower connecting portion 321R does not contact the 1 st fixing surface 121R even in the 2 nd rocking state. In this state, the 1 st fixing portion side magnet 65R is fixed to the 1 st receiving member 62R at a position in contact with the 1 st truss end portion side magnet 66R fixed to the 1 st holding member 63R. That is, when the truss 3 is installed, the 1 st truss end portion side magnet 66R and the 1 st fixing portion side magnet 65R are attracted to each other, and the 1 st supporting device 6R is in the 1 st holding state.
The conditions and actions of the switching operation between the 1 st holding state and the 1 st releasing state of the 1 st supporting device 6R are the same as those of the 1 st supporting device 4R in embodiment 1.
Fig. 17 is a side view showing the 2 nd supporting device 6L in the 1 st rocking state. Fig. 17 is a diagram corresponding to fig. 5 in embodiment 1.
The 2 nd support device 6L includes a 2 nd magnet device 64L and a 2 nd receiving member 62L. The 2 nd receiving member 62L is a plate-like member fixed to the 2 nd fixing portion 12L. The horizontal connecting portion 322L of the 2 nd support 32L is slidably mounted on the top surface portion of the 2 nd receiving member 62L.
The 2 nd magnet device 64L includes a 2 nd fixing portion side magnet 65L and a 2 nd truss end portion side magnet 66L. The 2 nd fixing portion side magnet 65L is fixed to the top surface portion of the 2 nd receiving member 62L. The 2 nd truss end portion side magnet 66L is fixed to the horizontal connecting portion 322L. Therefore, the 2 nd truss end portion side magnet 66L moves in accordance with the movement of the truss 3.
The mounting position of the 2 nd fixing portion side magnet 65L on the 2 nd receiving member 62L is determined as follows. First, when the truss 3 is provided, the truss 3 is provided so that the 2 nd gap 13L is provided between the vertical connecting portion 321L of the 2 nd support member 32L and the 2 nd fixing surface 121L of the 2 nd fixing portion 12L. The size of the 2 nd gap 13L is a size in which the lower connecting portion 321L is in contact with the 2 nd fixing surface 121L in the 2 nd rocking state. In the 2 nd rocking state, when the 2 nd gap 13L disappears, that is, when the vertical connecting portion 321L contacts the 1 st fixing surface 121R, the 2 nd fixing portion side magnet 65L is fixed at a position where the 2 nd truss end portion side magnet 66L contacts. That is, when the truss 3 is provided, the 2 nd fixing portion side magnet 65L does not contact the 2 nd truss end portion side magnet 66L. When the truss 3 is set, the 2 nd supporting device 6L is in the 2 nd released state.
The attraction force between the 2 nd fixing portion side magnet 65L and the 2 nd truss end portion side magnet 66L of the 2 nd supporting device 6L is stronger than the horizontal load determined by both the frictional force when the 1 st truss end portion 31R slides on the 1 st receiving member 62R and the horizontal inertial force of the truss 3 when the sway occurs, and is weaker than the attraction force between the 1 st fixing portion side magnet 65R and the 1 st truss end portion side magnet 66R of the 1 st supporting device 6R.
The attraction force between the 1 st fixing portion side magnet 65R and the 1 st truss end portion side magnet 66R of the 1 st supporting device 6R is stronger than the horizontal load determined by both the frictional force when the 2 nd truss end portion 31L slides on the 2 nd receiving member 62L and the horizontal inertial force of the truss 3 when the sway occurs, and is weaker than the compressive strength load of the truss 3.
In the 2 nd supporting device 6L, the conditions and actions of the switching operation between the 2 nd holding state and the 2 nd releasing state are the same as those of the 2 nd supporting device 4L in embodiment 1.
Fig. 18 is a side view showing the 1 st supporting device 6R of fig. 16 in the 2 nd rocking state. Fig. 18 is a view corresponding to fig. 7 in embodiment 1. Fig. 19 is a side view showing the 2 nd supporting device 6L of fig. 17 in the 2 nd rocking state. Fig. 19 is a diagram corresponding to fig. 8 in embodiment 1.
In embodiment 3 of the present invention, the 1 st supporting device 6R includes the 1 st fixing portion side magnet 65R and the 1 st truss end portion side magnet 66R. The 2 nd support device 6L includes a 2 nd fixing portion side magnet 65L and a 2 nd truss end portion side magnet 66L. In this way, by using the magnet, the 1 st holding state and the 1 st release state of the 1 st supporting device 6R can be switched, and the 2 nd holding state and the 2 nd release state of the 2 nd supporting device 6L can be switched. Further, since it is not necessary to spend time and effort for processing the grooves in the 1 st receiving member 62R and the 2 nd receiving member 62L, it is possible to reduce the time and effort for the manufacturing operation of the 1 st supporting device 6R and the 2 nd supporting device 6L, respectively.
In each of the above embodiments, the following modifications can be made.
In each of embodiments 1 to 3, fitting of components or attraction of magnets is used only for both the 1 st supporting device and the 2 nd supporting device. However, the 1 st supporting device and the 2 nd supporting device may be configured by combining the above-described respective aspects. For example, the 1 st supporting device may have a fitting structure, and the 2 nd supporting device may have a magnetic attraction structure. The 1 st support device may have a magnetic attraction structure, and the 2 nd support device may have a fitting structure. In this case, the same effects as those in embodiment 1 can be obtained.
In the present invention, the 1 st brace 32R and the 2 nd brace 32L are provided as other members at the 1 st truss end 31R and the 2 nd truss end 31L, respectively. The 1 st brace 32R and the 2 nd brace 32L may also be integrally formed with the 1 st truss end 31R and the 2 nd truss end 31L, respectively. In this case, the same effects as those in embodiment 1 can be obtained.
In each of embodiments 1 to 3, the present invention is applied to an escalator 2 that is a passenger conveyor provided between an upper floor 10 and a lower floor 11 having different floor heights. However, the present invention may be applied to a passenger conveyor, that is, a moving walkway, installed between floors at the same height, for example, in a place other than the upper floor 10 and the lower floor 11 having different floor heights. Furthermore, the present invention may also be applied to a passenger conveyor provided outside a building rather than inside the building. In any case, the same effects as those in embodiment 1 can be obtained.
In the present invention, the case where the building 1 is swayed by an earthquake is explained. However, the same effects as those in embodiment 1 can be obtained for the sway caused by wind or the sway caused by other factors other than the earthquake.
In the present invention, the embodiments may be freely combined or may be appropriately modified or omitted within the scope of the invention.
