Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a rail fastening device for railroad sleepers.

[0002]

[Prior art]

 The conventional rail fastening device for wooden sleepers is one in which the rail is placed on the wooden sleepers shown in Figs. 6 to 7, the dog nail is driven into the wooden sleepers, and the rails are directly pressed by the dog nails and fastened. Alternatively, mount the tie plate on the wooden sleepers shown in Figs. 8 to 9, fix the tie plate to the wooden sleepers with dog nails, and place the rubber pad and rail on the tie plates to secure it to the tie plate. Some bolts and nuts tighten the leaf spring to hold the rail and tighten it.

[0003]

[Problems to be solved by the device]

 Among the ones described in the prior art, the former is not elastic, and the dog nail supporting force due to repeated vibration of the train car load and corrosion of the sleeper decreases over time, so the rail pressing force decreases and the rail It also has a problem that the drag resistance is reduced, and a great deal of labor is spent on rail clearance adjustment and clearance management. Further, in the latter case, there are problems that the number of parts is large, the mounting is complicated, and a large amount of labor is spent on torque management of the bolt. The present invention has been made in view of the above problems of the prior art. The object of the present invention is to reduce the number of parts, to install easily, to have elasticity, and to use the rails with age. It is an object of the present invention to provide a rail sleeper rail fastening device for a wooden sleeper that can prevent a reduction in the pressing force and reduce a great amount of labor for adjusting the clearance between the rails and managing the clearance.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the rail fastening device for a wood sleeper according to the present invention comprises a steel rod having elasticity, bent at both ends to form an L-shape to form a rail pressing portion and a rail lateral pressure receiving portion, and a central portion. Is bent into a substantially W shape, and the rail clip of the spring clip holds the top of the rail base and the rail lateral pressure receiving part of the spring clip Arrange the rail clip so that it hits the side of the rail base and the sleeper retainer of the spring clip retains the top of the sleeper, and surround the tip of the rail screw with the rail screw retainer of the spring clip. The rail screw nail's collar holds the spring clip's rail screw nail receiver's upper surface, and the spring clip's rail's screw nail holder's lower surface touches the upper surface of the wrinkle. By screwing the compression screw for until rail, rail pressing portions of the spring clip to generate a rail holding force to wood sleepers for rail fastening device, characterized in that the fastening presses the rail.

[0005]

[Form of actual state of invention]

 The rail fastening device for wooden sleepers of the present invention secures the rail base by the rail lateral pressure receiving part of the spring clip with the rail screw and secures the gauge, and the rail pressing part of the spring clip secures the rail base. Hold the upper surface of the sleeper with the work clamp and sleeper retainer, and screw in the rail screwdriver until the rail clip's screw nail support located at a position higher than the spring clip rail retainer touches the sleeper upper surface. By pressing, the rail pressing force is generated and the rail is fastened.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 to 5, the spring clip (1) is formed by bending both ends of a spring steel having a wire diameter of 22 mm into an L shape to form a rail pressing portion (1a) and a rail lateral pressure receiving portion (1b). In addition, the central portion is bent into a substantially W shape to form the sleeper retainer portion (1c) and the rail screw nail receiving portion (1d).

The rail screw nail tip (2a) is inserted into the space (1g) surrounded by the rail screw nail receiving portion (1d) of the spring clip (1), and the collar portion (2) of the rail screw nail (2) is inserted. 2b) holds the rail screw nail receiving part upper surface (1e) of the spring clip (1), and the rail clip screw receiving part lower surface (1f) of the spring clip (1) contacts the sleeper upper surface (4a). By screwing in the rail screw nail (2) until the above, the rail pressing force is generated in the rail pressing portion (1a) of the spring clip (1), and the rail can be pressed and fastened.

[0008]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. Since the rails are fastened with elastic spring clips, the rail pressing force can be prevented from decreasing due to train load recoil vibration and sleeper corrosion, etc., and a great deal of effort can be saved for rail clearance adjustment and clearance management. .
