Description

Technical Field

[0001] The utility model relates to the technical field of rail fasteners, in particular to a track rail fastener. Background Art

[0002] Track rail fasteners, also known as intermediate connecting parts, are components that connect rails and sub-rail components (such as sleepers). The rails are firmly fixed to the sleepers through the fasteners to prevent them from moving. Track rail fasteners can effectively transfer the force borne by the rails to the sub-rail foundation to maintain the overall stability of the track structure.

[0003] A rail fastener disclosed in the existing patent announcement number CN217203395U includes a rail pad and T-bolts. The rail pad is fixed on the roadbed. The rail fastener also includes a gusset plate. The gusset plate includes a gusset plate body. The gusset plate body is provided with a first pressure strip and a second pressure strip in parallel. The gusset plate body is provided with a through hole. The gusset plate body is fixed to the rail pad by a fixing nut and a T-bolt passing through the through hole. The first pressure strip and the second pressure strip are parallel to the rail. A groove is provided on the rail pad, wherein the second pressure strip is pressed in the groove, and the first pressure strip presses the rail; the rail is pressed by the first pressure strip parallel to the rail, and the gusset plate body is fixed to the rail pad by a fixing nut and a T-bolt passing through the through hole.

[0004] In the above rail fastener, the rail can be fixed. When the gusset body is fixed, the first pressure strip on one side of the gusset body is used to press the rail. However, the gusset body is fixed in the middle. After fixation, the first pressure strip is subject to the force of the rail and is easy to warp. Its fixing stability still needs to be improved. In view of the above problems, a track rail fastener is proposed. Utility Model Content
