It has been drilled. The L-shaped metal fitting 5 is formed in a L-shaped cross section, and is composed of a plate-like bottom rectangular portion 5B and an upright portion 5A that rises from a short side edge on the rail side of the bottom portion 5B. Mounting holes 5E and 5F are formed in the bottom portion 5B so as to match the screw holes 3A, 3B and 3C and 3D of the base 3 and penetrate vertically. As shown in FIGS. 5 and 6, the L-shaped bracket 5 is attached to the base 3 with the upright portions 5 </ b> A and 5 </ b> A facing each other by the bolt screw 4. A round bar-shaped reinforcing metal fitting 9 is welded to the both sides 5G and 5H in the track direction of the L-shaped metal fitting 5 so that the upright portion 5A upper end portion and the bottom portion 5B outer end portion are obliquely connected so as not to interfere with the bolt screw 4. .

It is designed to be fitted. When the bolt screw 45 is screwed in the forward direction, the attachment plate 47 is pushed out to the rail 10 side via the push fitting 46 and comes into contact with the jaw portion 10A of the rail 10 and the seating portion upper surface 10B. Yes. When the bolt screw 45 is screwed in the opposite direction, it retracts from the rail 10 side, and the tip 45A is detached from the circular hole 46B.
[0026]
As shown in FIGS. 1, 2, and 3, a pin hole 33 is formed in the upper center of the other upright portion 15 </ b> A along the longitudinal direction of the base 3 between the mounting holes 16 </ b> A and 16 </ b> B. A stepped pin 34 is inserted into the pin hole 33. The stepped pin 34 has a small-diameter portion 34A and a large-diameter portion 34B. The small-diameter portion 34A is inserted into the pin hole 33 so that the large-diameter portion 34B protrudes toward the rail 10 side of the standing portion 15A. A splicing plate (seam plate) 36 is attached to the tip of the large-diameter portion 34B via a push fitting 35. The press fitting 35 is provided so as to be rotatable relative to the large diameter portion 34B of the stepped pin 34. In the pressing metal 35, a small diameter screw portion 35A is screwed into a screw hole formed in the attachment plate 36, and the tip of the large diameter portion 34B is loosely fitted in a circular hole 35B formed on the outer surface of the large diameter portion. It is like that. When the L-shaped metal fitting 15 is displaced to the rail 10 side together with the pedestal 13, the attachment plate 36 is pushed by the metal fitting 35 via the stepped pin 34 and comes into contact with the jaw portion 10 </ b> A of the rail 10 and the seating portion upper surface 10 </ b> B. It is like that. In addition, when the L-shaped metal fitting 15 is retracted from the rail 10, the accessory plate 36 is configured such that the stepped pin large diameter portion 34 </ b> B comes off from the circular hole 35 </ b> B.
[0027]
Each L-shaped metal fitting 15, 25 is provided with reinforcing metal fittings 50 A, 50 B, 50 C, 50 D made of right-angled triangular plates that are welded to the lower side of the standing portion outer surfaces 37, 48 and the bottom upper surfaces 38, 49. These reinforcing metal fittings 50A to 50D are provided on both sides in the track direction of the surface formed by the standing portion outer side surfaces 37 and 48 and the bottom portion upper surfaces 38 and 49, respectively. The top portions of the reinforcing metal fittings 50A to 50D are positioned at almost half the height of the standing portions 15A and 25A.
[0028]
Next, the operation of the breakage reinforcing device 12 according to the above embodiment will be described. As shown in FIGS. 1 and 2, the breakage reinforcing device 12 is used for a railway rail 10 for a damaged work target. For example, a guard rail (device) 11 is installed in the vicinity of the rail 10 along the track direction. In this case, the vicinity of the rail 10 means, for example, that the gap between the rail 10 and the guard rail 11 or the like is about 85 mm. First, the breakage reinforcing device 12 is inserted below the rail 10 with the pedestal 13 substantially aligned in the direction perpendicular to the track direction. Next, the attachment plate 36 to which the press fitting 35 is attached in advance is placed at the work target position of the rail 10 from the gap between the rail 10 and the guard rail 11, and the L-shaped fitting 15 into which the stepped pin 34 is inserted is attached. The tip of the large-diameter portion 34B of the stepped pin 34 is put into the large-diameter circular hole 35B of the press fitting 35 from the gap between the rail 10 and the guard rail 11, and the protrusion 17 of the L-shaped metal fitting 15 is inserted. Is placed in the groove 13A of the base 13. Next, when the protrusion outer surface 17A is applied to the groove 13A and the bolt screws 32A and 32B are inserted through the mounting holes 16A and 16B of the upright portion 15A and screwed, they are screwed into the screw holes 31A and 31B, and the L-shaped bracket 15 is attached to the base 13.
[0029]
Next, the support plate 47 is applied to the side opposite to the longitudinal direction of the pedestal 13, that is, the side where the guard rail 11 is not provided, and the tip 45A of the bolt screw 45 is inserted into the large diameter circular hole 46B of the pressing metal 46, The L-shaped bracket 25 is attached to the base 13. The attachment is performed by applying the protrusion outer surface 27A to the groove 13B and screwing the bolt screws 42A and 42B. Next, when the bolt screw 45 is screwed with a tool and the attachment plate 47 is pressed against the rail 10 side and further screwed, the pedestal 13 is displaced in the direction opposite to the pushing direction of the bolt screw 45, and the L-shaped metal fitting on the opposite side 15 is displaced together with the base 13, and the other attachment plate 36 is pressed against the rail 10. Further, when the bolt screw 45 is screwed so that both the splicing plates 36 and 47 are pressed against the rail 10 with equal force from both sides, the bolt screw 45 is restricted from further screwing, and the splicing plates 36, 47 is held in pressure contact with the rail 10. Thus, the installation work of the breakage reinforcing device 12 is completed. When removing the breakage reinforcement device 12, first, the bolt screw 45 is loosened with a tool, the bolt screws 42A, 42B, 32A, 32B are removed, the L-shaped brackets 25, 15 are detached from the base 13, and the base 13 is removed from the rail 10. Pull out from below.
[0030]
As described above, even if the gap between the rail 10 and the guard rail 11 is narrow (for example, 85 mm), the L-shaped metal fitting 15 has the tops of the right-angled triangular reinforcing metal fittings 50A and 50B approximately half the upright portion 15A. Since it is located at a height, it can be guided to the pedestal 13 from above or from the guard rail 11 side while avoiding interference with the guard rail 11. Further, since the bolt screws 32A and 32B are configured to perform screwing work with a tool at a position near the direction perpendicular to the track direction from the place where the rail 10 on the base 13 is placed, the rail on the base 13 A position away from the mounting position in a direction perpendicular to the track direction, that is, the upper surface of the bottom portion 15 is free of an area that requires a work by a tool, and the L-shaped metal fitting 15 is interposed between the rail 10 and the guard rail 11 at the time of attachment. If it is possible to secure even a space in which the upright portion 15A is arranged, it is possible to install the L-shaped bracket while avoiding interference with the guard rail 11 in the vicinity of the rail 10. For this reason, it is not necessary to remove the guard rail 11 during the work.
[0031]
Further, the bolt screws 32A, 32B, 42A, 42B for attaching the L-shaped brackets 15, 25 to the pedestal 13 can be inserted into the attachment holes 16A, 16B, 26A, 26B from above the upright portion 15, and the upright portion 15, that is, a tightening and removing operation can be performed with a tool at a position higher than the base 13 and close to the top surface of the rail 10. For this reason, it becomes easy to work with a tool and work efficiency improves.
[0032]
In addition, since the work of pressing the attachment plates 36 and 47 to the rail 10 can be performed with only the bolt screw 45 on one side in the direction perpendicular to the track direction of the rail 10, work efficiency is improved. Further, if the L-shaped metal fitting 15 not provided with the bolt screw 45 is arranged and attached on the side where the guard rail 11 is installed, it is easy to avoid interference with the guard rail 11.
[0033]
Furthermore, since the mounting holes 16A, 16B, 26A, and 26B are formed in the upright portions 15 and 25 on both sides in the direction perpendicular to the track direction, the bolt screws 32A, 32B, 42A, and 42B can be reduced in diameter. In addition, the upright portions 15 and 25 can be extended in the orbit direction to reduce the thickness. For this reason, the L-shaped metal fittings 15 and 25 can be reduced in size and weight. Further, since the mounting holes 16A, 16B, 26A, and 26B are formed on both sides in the direction perpendicular to the track direction, the supporting members such as the stepped pins 34 and the bolt screws 45 that support the attachment plates 36 and 47 are used as bolt screws. 32A, 32B and 42A, 42B can be arranged, respectively, and the attachment plates 36, 47 can be press-contacted with good balance.
[0034]
Further, since the pressing metal 35 is screwed into the screw hole 36A of the attachment plate 36 on the one L-shaped metal fitting 15 side, the position of the vertical direction with respect to the track direction can be obtained by screwing the pressing metal 35 forward and backward. Can be fine-tuned. For this reason, even if devices such as the guard rail 11 are provided on both sides in the direction perpendicular to the track direction of the rail 10, the degree of interference with the device can be reduced. Further, before the work, the distance between the rail 10 and the guard rail 11 can be determined by adjusting the position in the gauge direction of the adjustment side auxiliary plate 36 so as to avoid interference with the guard rail 11 and setting the distance from the standing portion 15A. Even if they are different, the L-shaped metal fitting 15 can be attached to the base 13 in accordance with the interval. Furthermore, if the distance between the adjustment side accessory plate 36 and the upright portion 15A is increased in advance, the length of the other bolt screw 45 can be shortened, so that the weight can be reduced and the screw of the other bolt screw 45 can be reduced. The turning work is shortened, and the time for the pressure contact work of the attachment plates 36 and 47 is shortened.
[0035]
Further, the L-shaped metal fittings 15 and 25 apply not only the bolt screws 32A, 32B, 42A and 42B but also the protrusions 17 to the pressure in the direction perpendicular to the orbital direction applied to the standing portions 15A and 25A at the time of press-fitting the attachment plates 36 and 47. 27, the L-shaped brackets 15 and 25 are reduced in size and weight, and the degree of interference with devices such as the guard rail 11 is reduced. Further, since vibration and impact from the rail 10 side are distributed by the bolt screws 32A, 32B, 42A, 42B and the projections 17, 27 and transmitted to the pedestal 13 side, wear of the bolt screws 32A, 32B, 42A, 42B is reduced. It is done.
[0036]
In addition, since the reinforcing metal fittings 50A, 50B, 50C, 50D are composed of right-angled triangular plates welded to the lower side of the upright portion outer surfaces 37, 48 and the bottom upper surfaces 38, 49, the strength is enhanced with a lightweight and compact shape. It can be ensured, the dimension perpendicular to the track direction can be shortened, the degree of interference with devices such as the guardrail 11 can be reduced, and the L-shaped brackets 15 and 25 are reduced in size and weight.
[0037]
Furthermore, since the reinforcing metal fittings 50A, 50B, 50C, 50D made of right-angled triangular plates are provided on both sides in the track direction of the L-shaped metal fittings 15, 25, strength can be ensured even if the thickness is reduced and the size is reduced. For this reason, the L-shaped metal fittings 15 and 25 are reduced in size and weight. Since the tops of the reinforcing metal fittings 50A, 50B, 50C, and 50D are provided so as to be positioned at almost half the height of the standing parts 15A and 25A, the degree of interference with devices such as the guard rail 11 is reduced.
[0038]
As described above, the breakage reinforcing device 12 according to the present embodiment can be attached to the rail 10 without removing the equipment such as the guard rail 11, so that the work efficiency is improved. Further, since the L-shaped metal fittings 15 and 25 can be attached with a tool at a position close to a direction perpendicular to the track direction of the rail 10 and near the upper surface of the rail 10, it is easy to work. In addition, since the pressing work of the attachment plates 36 and 47 can be performed from one side in a direction perpendicular to the track direction of the rail 10, that is, from one side of the L-shaped metal fittings 15 and 25, interference with the equipment can be prevented. If one L-shaped metal fitting 15 is arranged on the side of the device that is less likely to interfere and the other L-shaped metal fitting 25 is arranged on the opposite side where the device is not installed, the device is not removed. Can work on.
[0039]
Note that the breakage reinforcement device 12 according to the above-described embodiment can be used even if a device such as the guard rail 11 is not installed near the rail 10, and even in that case, the breakage reinforcement device 12 is significantly more than the conventional breakage reinforcement device. Needless to say, the working time can be shortened. In addition, a seam plate may be used for the attachment plates 36 and 47. Further, the stepped pin 34 can be used in various places where the distance from the device is different by using various pins having different axial dimensions of the large diameter portion 34B in accordance with the distance between the rail 10 and the guard rail 11 or the like.
