Description

Technical Field

[0001] The utility model relates to the technical field of railway tracks, in particular to a rail seam clamp. Background Art

[0002] The existing railway rails are composed of sections of rails connected together. Since objects have the characteristics of thermal expansion and contraction, a certain amount of gaps are left at the joints of the rails. When the wheels run over the gaps during train operation, due to the instantaneous sinking of the wheels and the step effect of the interface, strong vibrations and impact sounds are inevitably generated. This impact not only produces noise pollution, but also causes certain damage to the train, and also has a certain impact on the safe operation and speed of the train. For this reason, some countries use extra-long rails or seamless rails to eliminate the above-mentioned effects. Extra-long rails and seamless rails not only have high requirements on the roadbed and rail materials, but are also prone to thermal expansion deformation and bending, which increases the potential for accidents in the operation of trains. In addition, extra-long rails and seamless rails are expensive, especially for the replacement of the original rails, the cost is even higher.

[0003] Therefore, it is necessary to design a rail gap clamp that can eliminate the adverse consequences caused by the rail gap. Summary of the invention

[0004] In order to overcome the disadvantage that the original rail gap can cause the wheels to sink instantly and cause the impact, resulting in the swing of the two rails due to vibration, causing rail vehicle derailment and other adverse consequences, the technical problem to be solved is to provide a rail gap clamp that can eliminate the adverse consequences caused by the rail gap.

[0005] The technical solution is: a rail seam clamp, including a clamp, a gasket, a bolt and a nut that can be used in conjunction with it. The clamp fits the curvature of the waist of the rail body, and the clamp is fixed to the body rail of the rail body by bolts and nuts. Gaskets are placed between the bolts, nuts and the clamp.

[0006] As a further preferred solution, a boss integral with the upper portion of the clamp is provided at a position corresponding to the rail seam of the main rail body, and a groove corresponding to the boss is provided at the rail seam of the main rail body, and the boss fits in the groove.

[0007] As a further preferred solution, the gasket has a conical extension capable of being embedded in the nut, and the nut has an inner groove that serves as a limit.

[0008] As a further preferred solution, the clamping plate is in a "£" shape, and the surface of the clamping plate boss is flush with the surface of the rail body.

[0009] As a further preferred solution, the clamping plate is provided with a plurality of bolt holes, the waist portion of the rail body also has bolt holes matching the clamping plates, and the clamping plates are placed and attached to both sides of the rail body according to the corresponding bolt holes.

[0010] As a further preferred solution, bolts are passed between the rail body and the clamping plate, and the nuts and the bolts are connected via threads.

[0011] The utility model has the following advantages: 1. A boss which is an integral structure with the rail is arranged at the upper part of the clamping plate corresponding to the rail joint, and a groove corresponding to the boss is arranged at the rail joint. The boss is just located in the groove, and the surface of the boss is flush with the surface of the rail. When the rail joint clamping plate is used, the surface of the boss is flush with the surface of the rail, thus avoiding instant sinking of the wheel and eliminating the impact.

[0012] 2. The production and installation of the plywood of the utility model are very convenient and inexpensive, which greatly reduces the cost of modifying the original track and can shorten the construction period.

[0013] 3. When the nut is rotated to fix the splint, the conical extension on the gasket will be embedded in the groove inside the nut, thereby achieving positioning, making it fit more closely, forming a more stable structure, and preventing loosening due to vibration when the rail vehicle is running.

[0019] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] A rail seam clamp, such as Figure 1-4As shown, it includes a clamping plate 2, a gasket 3, a bolt 4 and a nut 5 that can be used in conjunction with it. The clamping plate 2 fits the curvature of the waist of the rail body 1, and the clamping plate 2 is fixed to the body rail of the rail body 1 by bolts 4 and nuts 5, and gaskets 3 are placed between the bolts 4 and the nuts 5 and the clamping plate 2; a boss integral with the rail seam of the rail body 1 is provided at the upper part of the clamping plate 2 corresponding to the rail seam of the rail body 1, and a groove corresponding to the boss is provided at the rail seam of the rail body 1, and the boss fits in the groove; the gasket 3 has a conical extension that can be embedded in the nut 5, and the nut 5 has an inner groove that plays a limiting role; the clamping plate 2 is "£"-shaped, and the surface of the clamping plate 2 boss is flush with the surface of the rail body 1; three bolt holes are opened on the clamping plate 2, and the waist part of the rail body 1 also has bolt holes matching the clamping plate 2, and the clamping plate 2 is placed and fit on both sides of the rail body 1 according to the corresponding bolt holes; bolts 4 pass through between the rail body 1 and the clamping plate 2, and the nuts 5 are connected to the bolts 4 by threads.
