加圧等によつて、固定ボルト４が次第に弛んで浮
きあがり、線路がぐらつくという難点があつた。 Conventionally, as shown in Fig. 1, railway tracks have two concrete sleepers 1 on which they intersect at right angles.
A book rail 2 is arranged, a rail fixing plate 3 is placed on the foot of the rail 2, and the fixing bolt 4 is tightened and fixed. A long nut 5 made of synthetic resin with a female thread carved into the inner hole is buried in the bolt fitting hole of the concrete sleeper 1, and the fixing bolt 4 is lubricated and tightened to prevent it from rusting due to rainwater, etc. Because of this, there was a problem in that the fixing bolts 4 gradually loosened and lifted due to vibrations of the train, lateral pressure applied to the rails 2, etc., causing the track to wobble.
そのため、固定ボルト４の頭部の回転を防止す
る弛み止め具が開発されているが、その使用にも
難点が生じて来た。 For this reason, a locking device has been developed to prevent the head of the fixing bolt 4 from rotating, but there have been some difficulties in its use.

いる。 That is, the rail fixing plate 3 has [one side of the flat part] bent downward to be parallel to the rail 2 to form a bent part 3a, and a bolt insertion hole 3b is bored in the upper surface and center of the flat part. It is set up. The lower surface of the tip of the rail fixing plate 3 is placed on the upper surface of the foot of the rail 2, the lower surface of the bent portion 3a is fitted into the fixing groove 1a of the sleeper 1, and the bolt 4 is inserted into the bolt insertion hole 3b. It is designed to be screwed into the nut 5 of the sleeper 1. Thus, the loosening stopper 6 has a bolt head fitting hole 6b drilled in the center of the flat plate 6a, and a hanging wall 6 by bending the both side edges of the flat plate 6a downward.
c, 6c are formed, and the lower ends of the hanging walls 6c, 6c are made to protrude inward to form locking protrusions 6d, 6d. From above, fit the bolt head fitting hole 6b into the head of the fixing bolt 4, and push the hanging walls 6c downward in sliding contact with both ends of the flat plate 6a, thereby locking the locking protrusion. The portions 6d and 6d are fitted so as to press against the lower edges of both ends of the flat plate 6a.

れてしまうため全く役に立たなくなつた。 However, conventional rails for conventional lines have a length of 1m.
A 50Kg rail was used, but in order to reduce the number of rail replacements due to wear, it was replaced with a 60Kg larger rail, and as a result, a member called Gauge 7 was used, as shown in the plan view in Figure 3. began to be used. This gauge 7 is a device to prevent the rail 2 from sliding in the direction of the fixing bolt 4, and is a device for preventing the rail 2 from sliding in the direction of the fixing bolt 4.
and the foot side end of the rail 4, and its width is formed to be the same as the width of the flat plate 6a, so both side surfaces are flush with each other. ing. Therefore, the locking protrusions 6d, 6d of the locking device 6 mentioned above come into contact with the side surface of the gauge 7, and easily come off upwards, making them completely useless.

ている。 The purpose of the present invention is to provide a bolt loosening device that eliminates the above-mentioned drawbacks.The present invention is designed to provide a bolt loosening stopper that eliminates the above-mentioned drawbacks. In a bolt loosening stopper that is installed as a cover over a rail fixing plate whose other side of the flat part is in contact with the upper surface of the rail leg and is fixed to the railroad ties with bolts, the bolt loosening stopper is attached to the upper surface of the flat part of the rail fixing plate. A rectangular flat plate on which a fitting hole for the bolt head is bored, and a rectangular flat plate provided vertically downward on one side in the longitudinal direction of the sleeper and cut at the end of the bent part side of the rail fixing plate. A hanging side wall having a notch formed therein, and a notch part that is engaged with the notch part of the hanging side wall formed at the tip thereof and inserted between the flat part and the bent part of the rail fixing plate to fix the rail together with the flat plate. It consists of a fixing rod that clamps the plate, and a hanging support that connects the base end of the fixing rod and the end of the rail fixing plate on the bending part side on the other side of the flat plate in the longitudinal direction of the sleeper. Therefore, the fixing rod is inserted between the bent part and the flat part of the rail fixing plate, and the flat plate is placed on the rail fixing plate with the bolt head fitting hole of the plate fitted onto the bolt head. However, by locking the notch at the tip of the fixing rod to the notch in the hanging side wall, the rail fixing plate is held between the flat plate and the fixing rod, so it can be removed like a conventional locking device. There is no need to worry about this at all, and it is effective in completely preventing bolt loosening.

壁１０に鈎部１２を形成してある。 A bolt head fitting hole 9 is provided in the center of the upper surface of the flat plate 8.
is drilled. The inner diameter of the bolt head fitting hole 9 is large enough to fit the head of the fixing bolt 4 of the rail fixing plate 3, and since the bolt head has a regular hexagonal shape on a plane, the hexagonal shape and the hexagonal shape When rotated 60 degrees concentrically, both hexagonal shapes fit into a 12-pointed star shape. The right side peripheral edge of the flat plate 8 has a downwardly downward side wall 10 bent at right angles to the flat plate.
A notch 11 facing downward is formed in the hanging side wall 10 on the side of the bent portion 3a of the rail fixing plate 3. The notch portion 11 is formed in a key shape, and a hook portion 12 is formed on the hanging side wall 10.
また平板８の左側端でレール固定板３の曲折部

されている。 A fixing rod 14 is fixed to the lower end of the support 13. The fixing rod 14 is in the form of a thin plate slightly longer than the width of the flat plate 8, and its wide surface is horizontal, and its proximal side is fixed to the support body 13. Outward facing cutout 1
5 is formed, and the notch 15 is formed in the hanging side wall 1.
The tip of the fixing rod 14 is configured to be elastically movable in the vertical and horizontal directions with the fixed portion of the fixing rod 14 as a base point.

させるのである。 Since the present invention is constructed as described above, when installing it on the rail fixing plate 3, first align the tip of the fixing rod 14 with the notch 11 of the hanging side wall 10 as shown by the dotted line in FIG. Release the stopped state, and as shown in FIG. 9, the entire bolt loosening stopper of the present invention stands in a slightly inclined state, and the fixing rod 14 is inserted between the flat part of the rail fixing plate 3 and the bent part 3a. Next, the entire bolt loosening stopper of the present invention is tilted in the direction of the arrow, and the flat plate 8 is placed on the upper surface of the flat part of the rail fixing plate 3 so that the fitting hole 9 is located in the insertion hole of the rail fixing plate 3. place At this time, the head of the bolt 4 is fitted into the fitting hole 9 of the flat plate 8. Then, the notch 15 at the tip of the fixing rod 14 is engaged with the notch 11 in the hanging side wall 10.
このように本考案ボルト弛み止め具は従来品の

定され、ボルト４頭部は平板８のボルト頭部嵌合
孔９に嵌合されているので、ボルト４は回動がで
きず、弛みが防止される。 In this way, the bolt loosening stopper of the present invention does not fix the installation using the locking protrusion at the lower end of the hanging wall, as in conventional products, but instead clamps and fixes the rail fixing plate 3 between the fixing rod 14 and the flat plate 8. Therefore, it has the feature that it can be installed even if there is a gauge 7, and the flat plate 8 is attached to the fixed rod 1.
4 and the hanging side wall 10, and the bolt 4 head is fitted into the bolt head fitting hole 9 of the flat plate 8, so the bolt 4 cannot be rotated and loosened. Prevented.
また、ボルト４の弛みがある場合には右回りと

が、その場合には前記固定杆１４先端部はボルト
４に接して左回り方向の力を受けることとなり、
前述の切欠き部１１と切欠き部１５との嵌合は離
脱しないばかりか、この固定杆１４によるボルト
弛み止め効果が更に高くなる。 Furthermore, if the bolt 4 is slack, it will rotate clockwise, and as a result, the flat plate 8 will also rotate clockwise, but in that case, the tip of the fixing rod 14 will contact the bolt 4 and rotate counterclockwise. I will receive power,
Not only does the aforementioned notch 11 and notch 15 fit into each other, but the fixing rod 14 is more effective in preventing bolt loosening.

る。 In addition, as shown in FIG. 10, in the loosening stopper of the present invention, cutouts 11 and 15, bolt holes 9, and a cutting line 17 between the flat plate and the fixing rod are cut from a single steel plate 16 in the first step. It can be manufactured in three steps by bending the dotted line portion in the figure as the second step of forming, so it also has the advantage of being able to be supplied at low cost.
