Japanese Patent No. 3851826

  However, if the vehicle applies a certain level of stress to the safety rail, the safety rail may be buckled. Further, when a safety rail is installed on the sleeper, there is a problem that the track maintenance work using a multiple tie tamper or the like cannot be easily performed.

  Then, the subject of this invention is providing the vehicle guard apparatus and the vehicle guard apparatus which improved the rigidity of the track | truck.

  Another object of the present invention is to provide a vehicle guard device that does not hinder track maintenance work.

  Hereinafter, the features of the invention will be described with reference to the reference numerals. Note that the reference numerals are for reference, and the features of the invention are not limited to the embodiments.

  The feature of the invention is to provide the following vehicle guard device. The vehicle guard device includes a guard (24) that holds a vehicle derailed from the main rail (11) having a sleeper (12) in the track (10). The apparatus includes a guard floor plate (21) attached to the sleeper (12) and provided with the guard (24). The apparatus includes a reinforcing plate (29) installed between the guard floor plate (21) and the end face of the sleeper (12).

  The guard floor plate (21) includes a first floor plate (22a) facing the end surface (12d) of the sleeper (12). The reinforcing plate (29) is installed between the end surface (12d) of the sleeper (12) and the first floor plate (22a). The reinforcing plate (29) is wider in area than the first floor plate (22a).

  The guard floor plate (21) includes a second floor plate (23b) attached to the upper surface of the sleeper (12) by a fastener (B3). The guard floor plate (21) includes a protective plate (27) disposed on the second floor plate (23b) and defining a hole (27a). The fastener (B3) is disposed in the hole of the protective plate.

  The guard (24) is disposed outside the end surface (12d) of the sleeper (12).

  The guard floor plate (21) includes a second floor plate (23b) attached to the upper surface of the sleeper (12) by a fastener (B3). The second floor board (23b) is narrower than the width of the sleeper (12).

  According to the features of the invention described above, the reinforcing plate transmits the stress received from the end face of the sleeper to the roadbed ballast (not shown), thereby improving the rigidity of the vehicle guard device and the track and preventing buckling.

  Since the reinforcing plate is wider in area than the first floor plate, the rigidity of the vehicle guard device and the track is further improved.

  The protection plate protects the fasteners without damaging them by allowing the vehicle wheels to pass over the fasteners and not contacting the fasteners.

  Since the guard is installed outside the sleeper end face, or the second floor board is narrower than the width of the sleeper, the track maintenance work by multiple tie tampers or the like is not hindered.

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

  With reference to FIG. 1, a track 10 extends along a main rail 11, PC sleepers 12 (hereinafter referred to as “sleepers”) arranged at predetermined intervals along the main rail 11, and the main rail 11. The vehicle guard device 20 is arranged.

  With reference to FIG. 2, each sleeper 12 is installed on a ballast. The main rail 11 is fixed to each sleeper 12 using a rail fastening device (not shown). Each sleeper 12 is formed in a substantially planar rectangular shape and a trapezoidal cross section, and spreads from the upper surface toward the lower surface. The upper surface of the sleeper 12 has a hole 12a in which a screw is formed for inserting the bolt B3. The upper surface of the sleeper 12 has recesses 12b and 12c on both sides of the main rail 11 for a rail fastening device (not shown).

  The vehicle guard device 20 includes a guard floor plate 21 fixed to every other end of the sleeper 12. The guard floor plate 21 may be fixed to each sleeper 12. The vehicle guard device 20 includes a guard material 24 as a guard fixed to the guard floor plate 21. The vehicle guard device 20 includes accessory plates 26A and 26B disposed on the guard member 24 at the joint portion 20a of the guard member 24 (see FIGS. 1 and 4). The vehicle guard device 20 includes a protection plate 27 disposed on the guard floor plate 21. The vehicle guard device 20 includes a rubber pad 28 disposed between the upper surface of the sleeper 12 and the guard floor plate 21. The vehicle guard device 20 includes a reinforcing plate 29 that is disposed between the longitudinal end surface 12 d of the sleeper 12 and the guard floor plate 21.

  The guard floor board 21 includes an L-shaped lower floor board 22 and an upper floor board 23 joined to the lower floor board 22.

  The lower floor plate 22 is formed by bending a steel plate at a right angle, and includes a side plate 22a and an upper plate 22b which are orthogonal to each other. The lower floor plate 22 includes a swash plate 22c extending between the side plate 22a and the upper plate 22b. The side plate 22a as the first floor plate faces the end surface 12d in the longitudinal direction of the sleeper 12. The side plate 22a is smaller than the end face 12d in the longitudinal direction of the sleeper 12 with respect to the area. The side plate 22a has a hole (no symbol) through which the bolt B1 passes.

  Referring to FIGS. 2 and 3, upper floor plate 23 includes a U-shaped support plate 23 a that supports guard material 24. The upper floor plate 23 includes a fixed plate 23b as a second floor plate that is disposed on the upper surface of the sleeper 12 and is continuous with the support plate 23a. The fixed plate 23 b is narrower than the width of the sleeper 12. Thereby, the track maintenance work by the multiple tie tamper is not hindered. The support plate 23a has side portions 23a1, 23a2 facing each other and a top portion 23a3 extending between the ends of the side portions 23a1, 23a2. The support plate 23a has three holes 23c extending in the vertical direction at the top 23a3. The support plate 23a has a nut N1 that is positioned in alignment with the hole 23c and is fixed to the lower surface of the top portion 23a3. The flat fixing plate 23 b is disposed on the rubber pad 28. The fixing plate 23 b has an elongated hole 23 e that coincides with the hole 12 a of the sleeper 12. The hole 23e allows the shaft portion of the bolt B3 to be inserted, and the head of the bolt B3 is disposed outside the hole 23e.

  The guard member 24 is disposed outside the end face 12d of the sleeper 12. The reason for this arrangement is to prevent the track maintenance work using a multiple tie tamper or the like around the main rail when the guard member 24 is on the sleeper 12. The length of the guard material is about 5 m, for example. Referring to FIG. 4, guard material 24 includes side plates 24a and 24b facing each other and a substrate 24c extending between the center portions of side plates 24a and 24b. The guard member 24 has, for example, an oval hole 24f of 100 mm arranged along the center line of the substrate 24c in accordance with the installation interval of the sleepers 12. This hole 24f can be used when there is an error due to the position of the sleeper 12 or when the sleeper moves during use. The reason for the three holes 23c in the upper floor plate 23 is to prepare for a case where the oblong hole 24f of 100 mm is insufficient. As a result, the guard member 24 can be installed even when the position of the sleeper 12 moves ± 100 mm.

  Referring to FIG. 3, the planar rectangular protection plate 27 is joined onto the fixed plate 23 b. The protection plate 27 has a circular hole 27a surrounding the hole 23e of the fixed plate 23b. The hole 27a accommodates the head of the bolt B3 as a fastener inside. The depth of the hole 27a is deeper than the axial length of the head of the bolt B3. Therefore, when the shaft portion of the bolt B3 is attached to the hole 12a of the sleeper 12, the upper surface of the protection plate 27 becomes higher than the head portion of the bolt B3. That is, the upper end of the bolt B3 retreats from the upper surface of the protection plate 27 into the hole 27a and does not protrude upward from the hole 27a.

  Referring to FIG. 2, the planar rectangular reinforcing plate 29 is wider than the end face 12d and the side plate 22a in the longitudinal direction of the sleeper 12 with respect to the area. The reinforcing plate 29 has a hole 29a into which the bolt B1 is inserted. Since the reinforcing plate 29 transmits the stress received from the end face 12d in the longitudinal direction of the sleeper 12 to the roadbed ballast (not shown), the rigidity of the vehicle guard device 20 and the track 10 is improved. Thereby, buckling of the vehicle guard apparatus 20 is prevented. The reinforcing plate 29 may be a planar circle, an ellipse, a triangle, or a polygon.

  Referring to FIG. 4, the attachment plates 26 </ b> A and 26 </ b> B are disposed between the guard members 24, and are disposed on the upper and lower surfaces of the substrate 24 c of the guard member 24. The accessory plates 26A and 26B are inserted between the side plates 24a and 24b of the guard member 24, and are fixed to one guard member 24 with bolts B2. The accessory plates 26A and 26B have holes 26a that are arranged along the center line and through which the bolts B2 pass. The hole 26 a coincides with the hole 24 d at the end of the guard member 24. The accessory plates 26A and 26B have side portions 26b and 26c where the side surface and the lower surface intersect, and the side portions 26b and 26c are chamfered obliquely with respect to the side surface and the lower surface. The accessory plate 26B has a nut N2 positioned and welded in alignment with the hole 26a.

  Next, a method for assembling the vehicle guard device 20 to the sleeper 12 will be described.

  The reinforcing plate 29 is inserted into the longitudinal end face 12d side of the sleeper 12 of the side plate 22a of the lower floor plate 22, a washer is attached to the bolt B1, and the bolt B1 is screwed into the respective screw holes of the side plate 22a and the reinforcing plate 29. Thereby, the reinforcing plate 29 is fixed to the lower floor plate 22.

  A rubber pad 28 is disposed on the upper surface of the sleeper 12. The fixing plate 23b of the upper floor plate 23 is placed on the rubber pad 28, and the hole 12a and the hole 23e of the sleeper 12 are aligned. A washer is attached to bolt B3. The shaft portion of the bolt B3 is inserted from the hole 27a of the protection plate 27, passes through the hole 23e of the fixing plate 23, and is screwed into the hole 12a of the sleeper 12. As a result, the guard floor plate 21 is fixed to the sleeper 12. The head of the bolt B <b> 3 is disposed in the hole 27 and is lower than the upper surface of the protection plate 27.

  A guard member 24 is installed on the support plate 23 a of the upper floor plate 23. That is, the top portion 23a3 is inserted between the side plates 24a and 24b of the guard material 24, and the substrate 24c of the guard material 24 is placed on the top portion 23a3. The square washer W1 is attached to the bolt B2, the bolt B2 is passed through the hole 24f of the substrate 24c, and fixed to the nut N1 with a screw. As a result, the guard member 24 is fixed to the guard floor plate 21. Next, the accessory plates 26A and 26B are disposed on the upper and lower surfaces of the substrate 24c of the adjacent guard material 24. A washer is attached to the bolt B2, the bolt B2 is passed through the hole 24d of the substrate 24c, and screwed into the nut N2. As a result, the accessory plates 26 </ b> A and 26 </ b> B are fixed to one guard member 24 and can be moved with respect to the other guard member 24.

  Next, the usage method of the vehicle guard apparatus 20 is demonstrated.

  The vehicle guard device 20 is installed in a section where damage is assumed by the derailed vehicle when the vehicle derails. For example, when a vehicle derails due to a collision between a train and a car at a railroad crossing in a densely populated residential area, it is assumed that the influence of the derailed vehicle on the surroundings is significant. In such a crossing section, the vehicle guard device prevents the vehicle from deviating from the track after the vehicle derails.

  In addition, when a vehicle derails in front of a structure built close to the railway building limit such as a railway bridge, a station yard, or a tunnel, the derailed vehicle collides with the structure. In order to prevent such a collision, the derailment vehicle is prevented from deviating outside the track before the structure, and the vehicle is guided to the inside of the building limit.

  That is, with reference to FIG. 2, the wheels of the traveling vehicle are moved from the rail 11 toward the vehicle guard device 20 in the lateral direction. The wheel rests on the protection plate 27 and further moves toward the guard member 24. When the wheel passes over the hole 27a of the protection plate 27, the wheel passes above the head of the bolt B3 and does not contact the head, thus protecting the bolt B3 without damaging it. The wheel hits the guard member 24 and stops moving in the lateral direction. Thereby, a wheel is fastened in the track 10 to prevent the vehicle from deviating from the track 10. Furthermore, since the reinforcing plate 29 transmits the stress received from the sleeper 12 to the roadbed ballast, the rigidity of the vehicle guard device 20 is improved and buckling is prevented.

  In addition, maintenance work of the track 10 is performed by a multiple tie tamper. At this time, the guard member 24 is disposed outside the end surface 12d of the sleeper 12, and the fixing plate 23b is narrower than the width of the sleeper 12, so that the tip of the tie tamper enters under the sleeper 12. The maintenance work is not hindered.

  According to the vehicle guard device 20 described above, the reinforcing plate 29 transmits the stress received from the end face 12d in the longitudinal direction of the sleeper 12 to the roadbed ballast, improves the rigidity of the vehicle guard device 20, and prevents buckling.

  Since the reinforcing plate 29 is wider than the side plate 22a of the lower floor plate 22, the rigidity is further improved.

  Since the protection plate 27 does not allow the vehicle wheel to pass over the bolt B3 to contact the bolt B3, the protection plate 27 protects the fastener B3 without damage.

  Since the guard 24 is installed outside the end face 12d of the sleeper 12, or the second floor plate 23b is narrower than the width of the sleeper 12, the track maintenance work by multiple tie tampers or the like is not hindered.

  The present invention is not limited to the embodiments, and modifications and changes of the embodiments are possible without departing from the spirit of the invention.
