Description

  The present invention relates to a rail device that guides a truck or the like that travels between different adjacent foundations.

  Conventionally, a rail device may be laid across two foundations due to the addition of a building of an automated warehouse. When an earthquake occurs in such a situation, different foundations move differently, and the rails sway in a complicated manner between the two foundations. In such a case, when a large force acts on the rail in the direction of compression, there is a problem that the rail is bent or damaged at the joint of the structure. Further, when a large force acts on the rail in the extending direction, there is a problem that the rail is torn at the joint of the structure.

  Therefore, Patent Document 1 describes an invention relating to a relay rail that is separated from the rail in response to shaking in various directions. According to this, since the relay rail is separated from the rail in response to the complicated movement due to the earthquake, it is possible to avoid bending or damage of the entire rail.

  However, recently, one or both of the two foundations have a seismic isolation structure, and when an earthquake occurs, the foundation itself shakes greatly horizontally and slowly, protecting the structure provided on the foundation. In some cases. In this case, it is necessary to widen the gap between the two foundations in order to prevent the two foundations from coming into contact with each other, and the length of the rail arranged between them becomes long.

  Therefore, it is difficult to support the load of a long rail only at the ends by simply disposing the rail in a bridge shape between the two foundations as in the conventional technique.

  The present invention has been made in view of the above problems, and protects a rail laid between two widely spaced foundations from shaking such as an earthquake, and in normal times, a rail is provided in a gap between the two foundations. The purpose of the present invention is to provide a rail device capable of supporting the load of

  In order to achieve the above-mentioned object, the rail device according to the present invention includes a first foundation, and a stepped portion that is provided with a gap from the first foundation and is stepped down one step from the foundation surface portion on the upper edge of the first foundation side. A rail device provided on a foundation that includes a second foundation and an intermediate substrate that has one end pivotally supported by the first foundation and the other end placed on the stepped portion and arranged to cover the gap. And a first rail installed on the first foundation, a second rail installed on the second foundation and arranged with a gap from the first rail, the first rail and the second rail. An intermediate rail that connects the rail and a support member that supports the end of the intermediate rail via the second rail while being movably mounted on the intermediate substrate are provided.

  According to this, in normal times, the load of the rail installed between two foundations arranged at wide intervals can be supported by the intermediate board, and the foundation moves in different directions due to an earthquake, etc. Even if it comes off, it is possible to support the end portion of the second rail in the protruding state and protect the second rail.

  Further, when the distance between the first foundation and the second foundation becomes narrow and the other end of the intermediate board rides on the foundation surface portion of the second foundation, the second foundation is responsive to the swing of the intermediate board. The mounting member may be provided with a rolling surface portion that keeps the position of the projecting end portion of the second rail constant with respect to, and the support member may have a contact portion that abuts on the rolling surface portion of the mounting member.

  According to this, even when the end portion of the intermediate substrate on the second foundation side rides on the foundation surface portion of the second foundation due to an earthquake or the like, the height of the second rail from the foundation surface portion can be maintained constant. Therefore, it is possible to prevent the tip end portion of the second rail from being bent by the support member pushing up the protruding end portion of the second rail due to the vertical movement of the intermediate substrate.

  As shown in these drawings, the rail device 100 is a device that is laid on a foundation 200 and is used to run a traveling vehicle, and includes a rail 101, a support member 102, and a mounting member 103. .. The foundation 200 is a structure including a base isolation mechanism such as a building, and includes a first foundation 201, a second foundation 202, and an intermediate substrate 203.

  The traveling vehicle is not particularly limited in the invention of the present application, but a traveling vehicle that travels on the rail 101 and automatically conveys luggage, or a traveling vehicle that travels on the rail 101 and holds it at a high location. A stacker crane or the like that can be transported up to is exemplified.

  The first foundation 201 and the second foundation 202 are provided with separate seismic isolation mechanisms, and move independently during an earthquake. The first foundation 201 and the second foundation 202 are provided with a gap 204 so as not to collide with each other when they are moved by an earthquake. In the case of the present embodiment, the first base 201 and the second base 202 are set so that their upper surfaces are at the same level (flush).

  A step portion 221 that is one step lower than the base surface portion 222 is provided on the upper edge of the first base 201 side of the second base 202. The step portion 221 is lowered by one step at a height such that the base surface portion 222 and the upper surface of the intermediate substrate 203 are at the same level when the intermediate substrate 203 is placed.

  The intermediate substrate 203 is a plate that covers the gap 204 between the first foundation 201 and the second foundation 202 for reasons such as safety when an operator normally passes between the first foundation 201 and the second foundation 202. It is a shaped member. One end of the intermediate substrate 203 (end on the X-axis positive side in the drawing) is axially supported on the upper end surface of the first base 201 on the second base 202 side. The direction of the rotation axis of the intermediate substrate 203 is arranged along a direction (Y-axis direction in the drawing) perpendicular to the alignment direction (X-axis direction in the drawing) of the first base 201 and the second base 202 on the horizontal plane. . On the other hand, the other end of the intermediate substrate 203 (the end on the X-axis negative side in the drawing) is placed on the step 221 of the second foundation 202. Further, the gap between the base surface portion 222 of the second base 202 and the upper end surface of the intermediate substrate 203 is set to be a short distance in a normal time. Specifically, the other end portion of the intermediate substrate 203 is provided with a hanging portion 231 that hangs downward and extends in the rotation axis direction, and the lower end surface of the hanging portion 231 corresponds to the step portion 221 of the second foundation 202. Abutting. As a result, there is less friction in the arrangement direction with respect to the stepped portion 221, and more friction in the rotation axis direction.

  In the case of the present embodiment, the intermediate substrate 203 is slidably attached to the first base 201 in the rotation axis direction. That is, the intermediate substrate 203 moves following the movement of the first base 201 in the direction in which the first base 201 and the second base 202 are arranged (the X-axis direction in the drawing), and moves in the rotation axis direction (in the drawing). In the Y-axis direction), as shown in FIG. 6, the second base 202 is moved by the frictional force between the second base 202 and the intermediate substrate 203, following the movement of the second base 202.

  The rail 101 is a member that forms the track of the traveling vehicle, and includes a first rail 111, a second rail 112, and an intermediate rail 113. In the case of the present embodiment, the rail device 100 includes a pair of rails 101 arranged in parallel. Hereinafter, one rail 101 will be described, but other rails 101 have the same members, mechanisms, and functions.

  The first rail 111 is a rail installed on the first base 201, and the end surface of the first rail 111 is arranged at substantially the same position as the end surface of the first base 201. The end surface of the first rail 111 is inclined so as to approach the second foundation 202 as it goes downward. The end of the first rail 111 is supported by the first foundation 201.

  The second rail 112 is a rail that is installed on the second foundation 202 and is arranged in a butted state with the first rail 111 with a gap. The end surface of the second rail 112 is arranged at the same position as the intermediate portion of the step portion 221 of the second foundation 202. The end surface of the second rail 112 is inclined so as to approach the first foundation 201 as it goes downward. Further, the end portion of the second rail 112 is supported by the second foundation 202 at a position far away from the end surface of the second foundation 202 in consideration of the amount of movement of the intermediate substrate 203 when an earthquake occurs. The second rail 112 projects from the first base 201 to the first base 201.

  The intermediate rail 113 is a rail that connects so as to fill the gap between the first rail 111 and the second rail 112. The intermediate rail 113 is arranged so as to form a series of rails 101 between the first rail 111 and the second rail 112 during normal times. The intermediate rail 113 has a trapezoidal shape in which the upper bottom is longer than the lower bottom in a side view so as to correspond to the inclination of the end surfaces of the first rail 111 and the second rail 112. Further, in a top view, the shape of the intermediate rail 113 is a rectangle having the same width as the first rail 111 and the second rail 112. In the case of the present embodiment, since the inclination of the end surface of the first rail 111 and the inclination of the end surface of the second rail 112 are the same, the shape of the intermediate rail 113 in a side view is an isosceles trapezoid.

  Since the intermediate rail 113 is in contact with the first rail 111 and the second rail 112 due to the inclination, as shown in FIG. 3, when the first rail 111 and the second rail 112 approach each other due to an earthquake. , It is designed to lift up. This avoids damage to the rail due to the earthquake.

  The support member 102 is a columnar member that is movably mounted on the intermediate substrate 203 in the extending direction of the second rail 112 and supports the end portion of the intermediate rail 113 via the second rail 112. In the case of the present embodiment, the upper end portion of the support member 102 is fixed to the second rail 112, and the lower end portion thereof is the abutting portion 121 that abuts on the mounting member 103 provided on the intermediate substrate 203. The contact part 121 is a rotating body so that the support member 102 in contact with the mounting member 103 can be smoothly moved while supporting the load of the second rail 112 and the intermediate rail 113. In addition, due to the structure of the foundation 200, the intermediate substrate 203 relatively moves with respect to the second rail 112 in the extending direction of the second rail 112 (X-axis direction in the drawing), and the width direction of the second rail 112 (see the drawing). Since it moves integrally in the middle Y-axis direction), the contact portion 121, which is a rotating body, has a cylindrical shape having a rotation axis in the width direction of the second rail 112 that rotates in the direction along the second rail 112. Has become a roller.

  In a normal state, the protruding end portion of the second rail 112 in the protruding state is supported by the intermediate substrate 203 via the support member 102, and the protruding portion does not bend due to its own weight or the weight of the intermediate rail 113. Is becoming

  In the mounting member 103, when the distance between the first foundation 201 and the second foundation 202 becomes narrow due to an earthquake or the like, and the other end of the intermediate substrate 203 rides on the foundation surface portion 222 of the second foundation 202, It is a member having a rolling surface portion 131 that keeps the position of the projecting end portion of the second rail 112 with respect to the second foundation 202 constant with respect to swinging about the width direction of the two rails 112.

  Specifically, as shown in FIG. 3, when the gap 204 between the first foundation 201 and the second foundation 202 is narrowed from the normal state shown in FIG. 1 due to an earthquake or the like, the step portion 221 of the second foundation 202 to the foundation surface portion 222 The other end of the intermediate substrate 203 rides on the inclined portion 223 provided between the intermediate substrate 203 and the intermediate substrate 203 swings. This is because the intermediate substrate 203 moves together with the first base 201 in the rail extending direction. In this state, since the intermediate rail 113 is sandwiched by the first rail 111 and the second rail 112, the oblique interfaces at both ends are displaced and the intermediate rail 113 is lifted off from the first rail 111 and the second rail 112. ..

  On the other hand, the intermediate substrate 203 and the mounting member 103 fixed to the intermediate substrate 203 move relative to the second base 202 following the movement of the first base 201, and the second base 202. Riding on the inclined portion 223. That is, the intermediate substrate 203 supporting the supporting member 102 is lifted from the step 221 of the second foundation 202. However, since the rolling surface portion 131 has a thickness that decreases toward the first foundation 201 in consideration of the amount of lifting, the position (height) of the support member 102 becomes constant and is supported by the support member 102. The height of the projecting end 114 (see FIGS. 3 and 4) of the second rail 112 that is open with respect to the second foundation 202 is constant.

  Further, as shown in FIG. 4, when the gap 204 between the first foundation 201 and the second foundation 202 becomes narrower from the state shown in FIG. 3, the intermediate substrate 203 rides on the foundation surface portion 222 and the intermediate substrate 203 further swings. The rolling surface portion 131 of the mounting member 103, which is fixed to the intermediate substrate 203, is thinner in consideration of the amount of lifting of the intermediate substrate 203, so that the position of the supporting member 102 is maintained constant. The height of the tip 114 (see FIGS. 3 and 4) of the second rail 112 is also maintained.

  As described above, in consideration of the stroke of the intermediate board 203 when an earthquake occurs, in the rail device 100 in which the fixed pillar 115 and the tip of the second rail 112 are set to be long so that the fixed pillar 115 and the intermediate board 203 do not interfere with each other. Even if there is, since the vicinity of the projecting end 114 is supported by the supporting member 102 supported by the intermediate substrate 203, the second rail 112 does not bend due to traveling of the traveling vehicle in normal times, and the intermediate rail 113 It becomes possible to firmly support. Further, even when the gap between the first foundation 201 and the second foundation 202 becomes narrow due to an earthquake or the like, the rolling surface portion 131 of the mounting member 103 keeps the distance between the second foundation 202 and the second rail 112 constant. Therefore, an unreasonable load is not applied to the tip portion of the second rail 112, and the second rail 112 can be maintained straight.

  In addition, in the case of the present embodiment, the mounting member 103 includes a flat surface portion 132 having a flat upper surface arranged in a bridging manner between the other end portion of the intermediate substrate 203 and the base surface portion 222 of the second base 202. There is.

  Specifically, as shown in FIG. 5, when the gap 204 between the first foundation 201 and the second foundation 202 becomes wider from the normal state shown in FIG. 1 due to an earthquake or the like, the intermediate substrate 203 also moves with respect to the second foundation 202. To do. Even in this state, the mounting member 103 is arranged in a bridge shape between the intermediate substrate 203 and the base surface portion 222, and the flat surface portion 132 supports the supporting member 102 so that the position of the supporting member 102 is constant, and the supporting member 102 is supported by the supporting member 102. The height of the tip 114 of the supported second rail 112 with respect to the second foundation 202 is maintained constant.

  As described above, since the mounting member 103 includes the flat surface portion 132, even when the first base 201 and the second foundation 202 move in the direction in which they are separated from each other, the flat surface portion 132 of the mounting member 103 causes the second base 202 and the second Since the distance from the rail 112 is maintained without changing, the support member 102 can support the second rail 112 in a straight state.

  The present invention is not limited to the above embodiment. For example, another embodiment realized by arbitrarily combining the constituent elements described in this specification or excluding some of the constituent elements may be an embodiment of the present invention. Further, the present invention also includes modified examples obtained by applying various modifications to the above-described embodiment, which are conceivable to those skilled in the art, without departing from the gist of the present invention, that is, the scope of the wording set forth in the claims. Be done.

  For example, although the case where both the first foundation 201 and the second foundation 202 are provided with the seismic isolation mechanism has been described, one of them may be provided with the seismic isolation mechanism, or the seismic isolation mechanism may not be provided. I don't care.

  Further, although the case where the inclined portion 223 is provided on the second foundation 202 has been described, in order for the intermediate substrate 203 to ride on the foundation surface portion 222 of the second foundation 202, the second foundation 202 and the intermediate substrate 203 need to be formed. At least one of the other ends may be provided with an inclination (regardless of whether it is linear or curved).

  Further, the wording such as "along" is used to allow an error (spread) within a range not departing from the gist of the present invention. In other words, the word "along" is used in the sense of including twists and intersections that include parallel and coincidence and are close to parallel and coincidence.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a rail arranged over a plurality of foundations.
