Description

  The present invention relates to an automatic settlement settlement apparatus and an automated settlement settlement sleeper in which a function for correcting level displacement is added to a sleeper body.

    The related automatic settlement settlement sleeper is an upper block that is fastened to the rail, a lower block that is installed on the road floor and that can accommodate the upper block, and is interposed between the upper block and the lower block in the longitudinal direction. A plurality of automatic squat correction devices that support the block. The automatic settlement corrector has an inner cylinder having a granular body and an outer cylinder that houses the inner cylinder. In addition, the automatic settlement correction device has a relatively large gap in the overlapping part of the inner cylinder and the outer cylinder, and the lateral movement of the outer cylinder is controlled by guide posts attached to both ends of the sleeper. The inner cylinder and the outer cylinder are prevented from interfering with or rubbing.

  Then, when non-uniform settlement occurs in a track structure such as a ballast track or a slab track, the inner cylinder and the outer cylinder are separated from each other, and the granular material moves from the inner cylinder into the outer cylinder to correct the non-uniform settlement. (See Patent Documents 1 and 2).

  Moreover, in related rail support, a granular material is accommodated in a rail support, and a part of granular material enters a tray through the hole of the lower surface of a support (refer patent document 3).

  In the above features, the guide mechanism is a rolling guide mechanism (30A-30D, 40A-40H, 50A-50D, 60A-60H).

  The rolling guide mechanism (30A-30D, 40A-40H, 50A-50D, 60A-60H) is formed between the side surface of the inner cylinder (21, 21C, 21D, 21E) and the side surface of the outer cylinder (22, 22C, 22D, 22E). Arranged between.

  The inner cylinders (21D, 21E) have guide walls (21h, 21j) arranged outside the outer cylinders (22D, 22E), and the rolling guide mechanisms (40A-40H, 50A-50D) are outer cylinders (22D, 22D). 22E) and the side walls of the guide walls (21h, 21j).

  The elastic member (34, 43, 54, 63) has a rolling surface of the rolling guide mechanism (30A-30D, 40A-40H, 50A-50D, 60A-60H) as the inner cylinder (21, 21C, 21D, 21E) or The rolling guide mechanism (30A-30D, 40A-40H, 50A-50D, 60A-60H) is urged by the applied preload so as to always contact the outer cylinder (22, 22C, 22D, 22E).

  The guide mechanism is a sliding guide mechanism (70A-70D, 80A-80D).

  The sliding guide mechanism (70A-70D, 80A-80D) is disposed between the side surface of the inner cylinder (21F, 21G) and the side surface of the outer cylinder (22F, 22G).

  The inner cylinder (21G) has a guide wall (21f) disposed on the outer side of the outer cylinder (22G), and the sliding guide mechanism (80A-80D) has a side surface of the outer cylinder (22G) and a side surface of the guide wall (21f). Between.

  The elastic members (73, 83) were provided so that the sliding surfaces of the sliding guide mechanisms (70A-70D, 80A-80D) are always in contact with the inner cylinder (21F, 21G) or the outer cylinder (22F, 22G). The sliding guide mechanism (70A-70D, 80A-80D) is biased by the preload.

  An automatic settlement settlement sleeper (10) according to the second feature of the present invention includes a sleeper body (11) fastened to a traveling rail (R1, R2), a sleeper body (11) and a granular body.

  Hereinafter, embodiments will be described in detail with reference to the drawings.

First Embodiment As shown in FIG. 1, an automatic settlement correction sleeper 10 is disposed on a road bed B1 and attached to a sleeper body 11 that crosses travel rails R1 and R2, and a sleeper body 11. It has automatic squat correction devices 20A and 20B.

  The sleeper body 11 extends long in the direction L1 across the traveling rails R1 and R2. The sleeper body 11 has recesses 11a and 11b extending in the width direction on the bottom surface. The sleeper body 11 is manufactured from reinforced concrete including prestressed concrete, FRP or other synthetic resin, wood, iron, or the like.

  The automatic squat correction devices 20A and 20B are disposed in the recesses 11a and 11b of the sleeper body 11, respectively. As shown in FIGS. 2 and 3, the automatic settlement correction devices 20 </ b> A and 20 </ b> B include an inner cylinder 21 fixed to the sleeper body 11, an outer cylinder 22 into which the inner cylinder 21 is inserted so as to be relatively movable, and an inner cylinder 21. Rolling guide mechanisms 30 </ b> A, 30 </ b> B, 30 </ b> C, 30 </ b> D disposed between the side surface of the outer cylinder 22 and the side surface of the outer cylinder 22.

  The inner cylinder 21 has a flat inner cylinder top wall 21a, an annular inner cylinder side wall 21b extending downward from the inner cylinder top wall 21a, and an inner cylinder bottom wall 21c extending from the lower end of the inner cylinder side wall 21b and covering the bottom opening. . Here, the inner cylinder top wall 21a, the inner cylinder side wall 21b, and the inner cylinder bottom wall 21c define a space S1. This space S1 is filled with the granular material G1. The granular material G1 is, for example, sand, a metal ball such as a bearing, a ceramic ball, or a resin ball. The inner cylinder bottom wall 21c has a discharge hole 21d for discharging the granular material G1.

The outer cylinder 22 has a bottomed cylindrical shape. The outer cylinder 22 has an outer cylinder bottom wall 22a facing the inner cylinder bottom wall 21c of the inner cylinder 21, and an annular outer cylinder side wall 22b extending upward from the outer cylinder bottom wall 22a. The outer cylinder side wall 22b surrounds the inner cylinder side wall 21b of the inner cylinder 21 from the outside. The outer cylinder side wall 22b and the inner cylinder side wall 21b have a clearance C1 therebetween. Concave portions 22c are provided at four locations on the inner side surface of the outer cylinder side wall 21b. The outer cylinder 22 is movable in the vertical direction V <b> 1 with respect to the inner cylinder 21 and accommodates the granular material G <b> 1 discharged from the inner cylinder 21.
The horizontal cross-sectional shapes of the inner cylinder 21 and the outer cylinder 22 include a circle, an ellipse, a rectangle, a triangle, a quadrangle, a polygon, and other shapes.

  Each of the rolling guide mechanisms 30 </ b> A to 30 </ b> D is disposed between the side surface of the outer cylinder 22 and the side surface of the inner cylinder 21. Each rolling guide mechanism 30 </ b> A to 30 </ b> D is in contact with a roller 31 as a rolling element, a roller holder 32 as a movable roller bearing that rotatably holds the roller 31, and a recess 22 c of the outer cylinder 22 in contact with the roller 31. The holder 33 is movably arranged, and has an elastic member 34 to which the holder 33 is attached and fixed to the bottom of the recess 22c. The elastic member 34 may not be inserted into the recess 22c and fixed to the recess 22c.

  Here, each roller 31 is made of metal or resin, for example. Each elastic member 34 is, for example, a coil spring, a leaf spring, a disc spring, or a rubber elastic member. The elastic member 34 urges the roller 31 by the applied preload so that the roller 31 is always in contact with the inner cylinder side wall 21b.

  In addition, each elastic member 34 receives a load greater than the set value when the inner cylinder 21 and the outer cylinder 22 come into contact with each other when a load greater than the set value is applied to the roll guide mechanism 30A-30D. It has a spring constant that is displaced so as not to act on.

  Next, with reference to FIGS. 4 and 5, a method of using the automatic settlement settlement sleeper 10 will be described.

  As shown in FIG. 4, for example, when the railway vehicle passes over the traveling rails R <b> 1 and R <b> 2, the road bed B <b> 1 sinks plastically. At this time, the automatic squat correction device 20A follows the bed B1 that has been stretched and sank.

  Specifically, as shown in FIG. 5, the outer cylinder 22 descends following the road bed B <b> 1, and a space is formed in the outer cylinder 22. The granular material G1 in the inner cylinder 21 is discharged into the outer cylinder 22 from the discharge hole 21d by its own weight. The granular material G <b> 1 is filled in the space of the outer cylinder 22 and supports the inner cylinder 21. Since the outer cylinder bottom wall 22a receives the load of the sleeper body 11 by its surface, the stress is distributed without concentrating the stress. As described above, the sleeper body 11 and the traveling rails R1 and R2 are kept horizontal.

  Here, the rolling guide mechanisms 30A-30D guide the relative movement of the inner cylinder 21 and the outer cylinder 22 in the vertical direction V1. That is, the roller 31 rotates to guide the relative movement between the outer cylinder 22 and the inner cylinder 21.

  When a horizontal force is applied to the sleeper body 11, for example, the inner cylinder 21 moves to the right in the horizontal direction L1 with respect to the outer cylinder 22. At this time, the inner cylinder 21 pushes the roller 31 of one rolling guide mechanism 30A toward the outer cylinder side wall 22b, and compresses the elastic member 34. On the other hand, the elastic member 34 of the other rolling guide mechanism 30 </ b> B extends to cause the roller 31 to follow the inner cylinder 21. Thereby, the rolling guide mechanisms 30 </ b> A and 30 </ b> B can absorb the horizontal movement of the inner cylinder 21.

  Further, a larger horizontal force is applied to the sleeper body 11, and the inner cylinder 21 tends to move in the horizontal direction L1 with respect to the outer cylinder 22. At this time, the inner cylinder side wall 21b pushes the roller 31 of the rolling guide mechanism 30A into the recess 22c. Further, the inner cylinder side wall 21b hits the outer cylinder side wall 22b and stops. Thereby, the load more than a setting value does not act on the rolling guide mechanism 30A, and the rolling guide mechanism 30A can be protected. Thereafter, the horizontal force from the track can be transmitted to the bed B1.

  According to the above embodiment, the rolling guide mechanisms 30A-30D guide the relative movement of the inner cylinder 21 and the outer cylinder 22, and thus achieve a smooth operation of the inner cylinder 21 and the outer cylinder 22.

  The rolling guide mechanisms 30 </ b> A to 30 </ b> D can absorb the horizontal movement of the inner cylinder 21 by the expansion and contraction of the elastic member 34.

  Since the roller 31 is accommodated in the recess 22c with a predetermined load, a load greater than the set value is not applied to the rolling guide mechanism 30A-30D, and the rolling guide mechanism 30A-30D can be protected. Further, the horizontal force from the track can be reliably transmitted to the road bed B1.

  In addition, the number of installation locations of the rolling guide mechanisms 30A to 30D is not limited to this embodiment, and may be a plurality of different locations. Further, the rolling surface of the rolling guide mechanism 30A-30D may be either the inner cylinder 21 or the outer cylinder 22, and the rolling guide mechanism 30A-30D may be provided on the inner cylinder 21 and the outer cylinder 22 may be used as the rolling surface.

Second Embodiment As shown in FIGS. 6 and 7, the automatic squat correction device 20 </ b> C includes rolling guide mechanisms 40 </ b> A to 40 </ b> H using a roller 41 as a rolling element.

  The rectangular outer cylinder 22C has four concave portions 22e arranged in two rows in the vertical direction and two rows in the horizontal direction on one side of the outer cylinder side wall 22d.

  Each rolling guide mechanism 40A-40H is disposed between the side surface of the outer cylinder 22C and the side surface of the inner cylinder 21C. Each rolling guide mechanism 40A-40H includes a roller 41 as a rolling element, a roller holder 42 that rotatably holds the roller 41 and is movably disposed in the recess 22e of the outer cylinder 22C, and a roller holder 42. The elastic member 43 is attached and fixed to the bottom surface of the recess 22e. The elastic member 43 may not be inserted into the recess 22e and fixed to the recess 22e.

  Here, each roller 41 is made of metal or resin. A ball may be used as the rolling element instead of the roller 41. Each elastic member 43 is, for example, a coil spring, a leaf spring, a disc spring, or a rubber elastic member. Each elastic member 43 urges the roller 41 by a given preload so that the roller 41 is always in contact with the inner cylinder side wall 21b. Further, the elastic member 43 causes the inner cylinder 21C and the outer cylinder 22C to come into contact with each other when the load greater than the set value is applied to the rolling guide mechanisms 40A-40H, and the load greater than the set value is applied to the roll guide mechanisms 40A-40H. It has a spring constant that is displaced so as not to act.

  According to the rolling guide mechanisms 40A-40H described above, when the outer cylinder 22C moves in the vertical direction V1 with respect to the inner cylinder 21C, the roller 41 rotates to guide the relative movement between the outer cylinder 22C and the inner cylinder 21C. .

  When a horizontal force is applied to the sleeper body 11, the inner cylinder 21C moves to the right in the horizontal direction L1 with respect to the outer cylinder 22C. At this time, the inner cylinder 21C presses the rollers 41 and 41 of the rolling guide mechanisms 40A and 40C on one side toward the outer cylinder side wall 22d, and compresses the elastic members 43 and 43. On the other hand, the elastic members 43 and 43 of the rolling guide mechanisms 40B and 40D on the other side extend to cause the rollers 41 and 41 to follow the inner cylinder 21C. Thereby, the rolling guide mechanisms 40A to 40D can absorb the horizontal movement of the inner cylinder 21C.

  A larger horizontal force is applied to the sleeper body 11, and the inner cylinder 21C moves to the right in the horizontal direction L1 with respect to the outer cylinder 22C. At this time, the inner cylinder side wall 21b pushes the rollers 41 and 41 of the rolling guide mechanisms 40A and 40C into the recess 22e. Furthermore, the inner cylinder side wall 21b hits the outer cylinder side wall 22d and stops. Thereby, the load more than a setting value does not act on rolling guide mechanism 40A, 40C, and it can protect rolling guide mechanism 40A, 40C. Further, the horizontal force from the track can be transmitted to the road bed B1.

  The number of installation locations of the rolling guide mechanisms 40A-40H is not limited to this embodiment, and may be a plurality of different locations. Further, the rolling surfaces of the rolling guide mechanisms 40A-40H may be either the inner cylinder 21C or the outer cylinder 22C, and the rolling guide mechanisms 40A-40H may be provided on the inner cylinder 21C and the outer cylinder 22C may be used as the rolling surface.

Third Embodiment As illustrated in FIGS. 8 and 9, the automatic squat correction device 20D includes rolling guide mechanisms 50A to 50D.

  The outer cylinder 22D has an annular outer cylinder side wall 22g extending upward from the outer cylinder bottom wall 22a. The inner cylinder 21D has an inner cylinder top wall 21e that extends outward beyond the inner cylinder side wall 21b and the outer cylinder side wall 22g. The inner cylinder 21D has a rectangular guide wall 21h extending downward from the outer periphery of the inner cylinder top wall 21e. The guide wall 21h is disposed outside the outer cylinder side wall 22g and extends in parallel with the outer cylinder side wall 22g. The guide wall 21h and the outer cylinder side wall 22g have a clearance C2. The guide wall 21h has a recess 21i at the center of each side.

  Each rolling guide mechanism 50A-50D is disposed between the side surface of the outer cylinder 22D and the side surface of the guide wall 21h. Each rolling guide mechanism 50A-50D includes a roller 51 as a rolling element in contact with an outer surface of the outer cylinder side wall 22g of the outer cylinder 22D, a movable roller holder 52 that rotatably holds the roller 51, A holder 53 that is in contact with and movably accommodated in the recess 21i, and an elastic member 54 to which the holder 53 is attached and fixed to the bottom of the recess 21i. The elastic member 54 may not be inserted into the recess 21i and fixed to the recess 21i.

  Here, each roller 51 is made of metal or resin. A ball may be used instead of the roller 51. Each elastic member 54 is, for example, a coil spring, a leaf spring, a disc spring, or a rubber elastic member. Each elastic member 54 urges the roller 51 with a given preload so that the roller 51 is always in contact with the outer cylinder side wall 22g. In addition, each elastic member 54 causes the inner cylinder 21D and the outer cylinder 22D to come into contact with each other when the load greater than the set value is applied to the rolling guide mechanisms 50A-50D, and the load greater than the set value rolls the guide mechanisms 50A-50D. It has a spring constant that is displaced so as not to act on.

  According to the rolling guide mechanisms 50A-50D described above, when the outer cylinder 22D moves in the vertical direction V1 with respect to the inner cylinder 21D, the roller 51 rotates on the outer cylinder side wall 22g and moves the outer cylinder 22 in the vertical direction V1. invite.

  When a horizontal force is applied from the sleeper body 11 to the inner cylinder 21D, for example, the inner cylinder 21D moves to the right in the horizontal direction L1 with respect to the outer cylinder 22D. At this time, the guide wall 21h moves to the right in the horizontal direction L1 in the drawing, for example. The guide wall 21h compresses the elastic members 54, 54 of the rolling guide mechanism 50B, while the elastic members 54, 54 of the rolling guide mechanism 50A extend to cause the rollers 51, 51 to follow the outer cylinder side wall 22g. Thereby, the rolling guide mechanisms 50A-50D can absorb the horizontal movement of the inner cylinder 21D.

  A larger horizontal force is applied to the sleeper body 11, and the inner cylinder 21D tends to move to the right in the horizontal direction L1 with respect to the outer cylinder 22D. At this time, the guide wall 21h pushes the roller 51 of the rolling guide mechanism 50B into the recess 21i. Further, the guide wall 21h comes into contact with the outer cylinder side wall 22g and stops. Thereby, the load beyond a setting value does not act on the rolling guide mechanism 50B, and the rolling guide mechanism 50B can be protected. Further, the horizontal force from the track can be transmitted to the road bed B1.

  Note that the number of installation locations of the rolling guide mechanisms 50A to 50D is not limited to this embodiment, and may be a plurality of different locations. Further, the rolling guide mechanism 50A-50D may be either a guide wall 21h or an outer cylinder 22D, or the rolling guide mechanism 50A-50D may be provided on the outer cylinder 22D and the guide wall 21h may be used as a rolling surface.

Fourth Embodiment As shown in FIGS. 10 and 11, the automatic settlement apparatus 20E includes rolling guide mechanisms 60A-60H.

  The outer cylinder 22E has an annular outer cylinder side wall 22h extending upward from the outer cylinder bottom wall 22a. The inner cylinder 21E has an inner cylinder top wall 21e that extends outward beyond the inner cylinder side wall 21b and the outer cylinder side wall 22h. The inner cylinder 21E has a rectangular guide wall 21j extending downward from the outer periphery of the inner cylinder top wall 21e. The guide wall 21j extends in parallel with the inner cylinder side wall 21b. The outer cylinder side wall 22h is disposed between the inner cylinder side wall 21b and the guide wall 21j. The outer cylinder side wall 22h extends in parallel with the guide wall 21j. The outer cylinder side wall 22h has a plurality of recesses 22j opened to the outside. The outer cylinder side wall 22h and the guide wall 21j have a clearance C2 between them.

  Each rolling guide mechanism 60A-60H is disposed between the side surface of the outer cylinder 22E and the side surface of the guide wall 21j. Each rolling guide mechanism 60A-60H includes a roller 61 as a rolling element in contact with the inner surface of the guide wall 21j, a roller holder 62 that rotatably holds the roller 61 and is movably accommodated in the recess 22j, and a roller A retainer 62 is attached and has an elastic member 63 fixed to the bottom of the recess 22j. The elastic member 63 may not be inserted into the recess 22j and fixed to the recess 22j.

  Here, each roller 61 is made of metal or resin. A ball may be used instead of the roller 61. Each elastic member 63 is, for example, a coil spring, a leaf spring, a disc spring, or a rubber elastic member. Each elastic member 63 urges the roller 61 with a given preload so that the roller 61 always contacts the guide wall 21j. Further, each elastic member 63 causes the inner cylinder 21E and the outer cylinder 22E to come into contact with each other when the load greater than the set value is applied to the rolling guide mechanisms 60A-60H, and the load greater than the set value rolls the guide mechanisms 60A-60H. It has a spring constant that is displaced so as not to act on.

  According to the rolling guide mechanisms 60A-60H described above, when the outer cylinder 22E moves in the vertical direction V1 relative to the inner cylinder 21E, the roller 61 rotates on the guide wall 21j and guides the outer cylinder 22E in the vertical direction V1. To do.

  When a horizontal force is applied from the sleeper body 11 to the inner cylinder 21E, for example, the inner cylinder 21E moves to the right in the horizontal direction L1 with respect to the outer cylinder 22E. At this time, the guide wall 21j moves to the right in the horizontal direction L1 in the drawing. The guide wall 21j compresses the elastic members 63 and 63 of the rolling guide mechanisms 60B and 60D, while the elastic members 63 and 63 of the rolling guide mechanisms 60A and 60C extend to cause the rollers 61 and 61 to follow the guide wall 21j. . Thereby, rolling guide mechanism 60A-60D can absorb the horizontal movement of the inner cylinder 21E.

  A larger horizontal force is applied to the sleeper body 11, and the inner cylinder 21E moves to the right in the horizontal direction L1 with respect to the outer cylinder 22E. At this time, the guide wall 21j pushes the rollers 61 and 61 of the rolling guide mechanisms 60B and 60D into the recesses 22j and 22j. Further, the guide wall 21j comes into contact with the outer cylinder side wall 22h and stops. Thereby, the load beyond a setting value does not act on the rolling guide mechanisms 60B and 60D, and the rolling guide mechanisms 60B and 60D can be protected. Further, the horizontal force from the track can be transmitted to the road bed B1.

  In addition, the number of installation locations of the rolling guide mechanisms 60A-60H is not limited to this embodiment, and may be a plurality of different locations.

Each of the sliding guide mechanisms 70A-70D includes a sliding guide member 71 in contact with the outer side surface of the inner cylinder side wall 21b of the inner cylinder 21F, and a retainer that is slidably accommodated in the recess 22c to which the sliding guide member 71 is fixed. 72 and an elastic member 73 to which the retainer 72 is attached and fixed to the bottom of the recess 22c. The elastic member 73 may not be inserted into the recess 22c and fixed to the recess 22c. Further, the sliding guide member 71 may be held by being pressed against the inner cylinder side wall 21b by the holder 72 without being fixed to the holder 72.

  The sliding guide member 71 uses, for example, a lubricating metal or a lubricating resin. The sliding guide member 71 is, for example, a quadrangular prism. The sliding guide member 71 is not limited to a rectangular prismatic body, and may be a semicircular or semi-elliptical cylindrical body, a triangular prismatic body, a trapezoidal prismatic body, or a polygonal prismatic body, and its shape is limited. Not.

  The elastic member 73 is disposed in the horizontal direction and can be expanded and contracted in the horizontal direction. The elastic member 73 is, for example, a coil spring, a plate spring, a disc spring, or a rubber elastic member. The elastic member 73 urges the sliding guide member 71 by the applied preload so that the sliding guide member 71 is always in contact with the inner cylinder side wall 21b. Further, the elastic member 73 causes the inner cylinder 21F and the outer cylinder 22F to come into contact with the sliding guide mechanisms 70A-70D when a load greater than the set value is applied to the sliding guide mechanisms 70A-70D. It has a spring constant that is displaced so as not to act.

  Further, the sliding guide mechanisms 70A-70D may be attached to the circumferential portion of the inner cylinder side wall 21b and the outer cylinder side wall 22b as long as the inner cylinder side wall 21b and the outer cylinder side wall 22b are cylindrical (including a circle and an ellipse). If the inner cylinder side wall 21b and the outer cylinder side wall 22b are square (including rectangle, triangle, quadrangle, polygon) or other shapes, the slip guide mechanism 70A-70D is attached to the side wall or the corner. Also good.

  Further, the sliding guide mechanisms 70A-70D may be attached to the recesses of the inner cylinder side wall 21b so that the sliding guide member 71 contacts the outer cylinder side wall 22b.

  The above sliding guide mechanisms 70A-70D guide the relative movement of the inner cylinder 21F and the outer cylinder 22F in the vertical direction V1. That is, the sliding guide member 71 slides on the inner cylinder side wall 21b and guides the inner cylinder 21F and the outer cylinder 22F in the vertical direction V1.

  When a horizontal force is applied to the sleeper body 11, the inner cylinder 21F moves to the right in the horizontal direction L1 with respect to the outer cylinder 22F. At this time, the inner cylinder 21F presses the sliding guide member 71 of the rolling guide mechanism 70A on one side toward the outer cylinder side wall 22b, and compresses the elastic member 73. On the other hand, the elastic member 73 of the slip guide mechanism 70B on the other side extends to cause the slide guide member 71 to follow the inner cylinder 21F. Thereby, the sliding guide mechanisms 70A and 70B can absorb the horizontal movement of the inner cylinder 21F.

  A larger horizontal force is applied to the sleeper body 11, and the inner cylinder 21F moves to the right in the horizontal direction L1 with respect to the outer cylinder 22F. At this time, the inner cylinder side wall 21b pushes the slip guide member 71 of the slip guide mechanism 70A into the recess 22c. Further, the inner cylinder side wall 21b hits the outer cylinder side wall 22b and stops. Thereby, the load more than a setting value does not act on the sliding guide mechanism 70A, and the sliding guide mechanism 70A can be protected. Further, the horizontal force from the track can be transmitted to the road bed B1.

  In addition, the number of installation locations of the sliding guide mechanisms 70A to 70D is not limited to the present embodiment, and may be a plurality of different locations. The sliding surfaces of the sliding guide mechanisms 70A-70D may be either the inner cylinder 21F or the outer cylinder 22F. The sliding guide mechanisms 70A-70D may be provided on the inner cylinder 21F, and the outer cylinder 22F may be used as the sliding surface.

Sixth Embodiment As shown in FIGS. 14 and 15, the automatic squat correction device 20 </ b> G includes slip guide mechanisms 80 </ b> A to 80 </ b> D. The outer cylinder 22G has an annular outer cylinder side wall 22f extending upward from the outer cylinder bottom wall 22a. The inner cylinder 21G has an inner cylinder top wall 21e extending outward in the horizontal direction L1 beyond the inner cylinder side wall 21b and the outer cylinder side wall 22f. The inner cylinder 21G has a rectangular guide wall 21f extending downward from the outer periphery of the inner cylinder top wall 21e. The guide wall 21f is disposed outside the outer cylinder side wall 22f and extends in parallel with the inner cylinder side wall 21b and the outer cylinder side wall 22f. The guide wall 21f has a recess 21g at the center of each side. The guide wall 21f and the outer cylinder side wall 22f have a clearance C2 between them.

  Each sliding guide mechanism 80A-80D is disposed between the side surface of the outer cylinder 22G and the side surface of the guide wall 21f. Each of the sliding guide mechanisms 80A-80D includes a sliding guide member 81 in contact with the outer surface of the outer cylinder side wall 22f of the outer cylinder 22G, and a retainer 82 to which the sliding guide member 81 is fixed and slidably received in the recess 21g. And the retainer 82 is attached and the elastic member 83 is fixed to the bottom of the recess 21g. The elastic member 83 may not be inserted into the recess 21g and fixed to the recess 21g. Further, the sliding guide member 81 may be held by being pressed against the outer cylinder side wall 22f by the cage 82 without being fixed to the cage 82.

  Here, each sliding guide member 81 is made of metal or resin. The elastic member 83 is, for example, a coil spring, a leaf spring, a disc spring, or a rubber elastic member. The elastic member 83 urges the sliding guide member 81 by the applied preload so that the sliding guide member 81 is always in contact with the outer cylinder side wall 22f. In addition, the elastic member 83 causes the inner cylinder 21G and the outer cylinder 22G to come into contact with each other when a load greater than the set value is applied to the slide guide mechanisms 80A-80D, and the load greater than the set value is applied to the slide guide mechanisms 80A-80D. It has a spring constant that is displaced so as not to act.

  According to the above sliding guide mechanisms 80A-80D, when the outer cylinder 22G moves in the vertical direction V1 with respect to the inner cylinder 21G, the sliding guide member 81 slides with the outer cylinder side wall 22f and moves the outer cylinder 22G in the vertical direction. Guide to V1.

  When a horizontal force is applied to the sleeper body 11, the inner cylinder 21G moves to the right in the horizontal direction L1 with respect to the outer cylinder 22G. At this time, the guide wall 21f moves to the right in the horizontal direction L1 in the drawing. The guide wall 21f compresses the elastic member 83 of the sliding guide mechanism 80B, while the elastic member 83 of the sliding guide mechanism 80A extends to cause the sliding guide member 81 to follow the outer cylinder side wall 22f. Thereby, the sliding guide mechanisms 80A and 80B can absorb the horizontal movement of the inner cylinder 21G.

  A larger horizontal force is applied to the sleeper body 11, and the inner cylinder 21G tends to move to the right in the horizontal direction L1 with respect to the outer cylinder 22G. At this time, the guide wall 21f pushes the slide guide member 81 of the slide guide mechanism 80B into the recess 21g. Furthermore, the guide wall 21f hits the outer cylinder side wall 22f and stops. Thereby, the load more than a setting value does not act on the sliding guide mechanism 80B, and the sliding guide mechanism 80B can be protected. Further, the horizontal force from the track can be transmitted to the road bed B1.

  The number of installation locations of the sliding guide mechanisms 80A to 80D is not limited to the present embodiment, and may be a plurality of different locations. Further, the sliding surface of the sliding guide mechanism 80A-80D may be either the guide wall 21f or the outer cylinder 22G, and the sliding guide mechanism 80A-80D may be provided on the outer cylinder 22G and the guide wall 21f may be used as the sliding surface.

  In addition, this invention is not limited to this embodiment, Moreover, each embodiment can be changed and corrected in the range which does not change the meaning of invention.
