Description

Technical Field

[0001] This utility model belongs to the field of high-speed rail fastener technology, specifically relating to a double-spiked track gauge baffle for high-speed rail fasteners. Background Technology

[0002] With the rapid development of high-speed railways, the stability of track structures is crucial to train operation safety. As a key component of the track fastening system, the gauge baffle's primary function is to maintain track gauge; its resistance to lateral forces directly affects the gauge-keeping capability and track smoothness.

[0003] Domestic railways widely use single-spiked gauge blocks (such as WJ-7 and WJ-8 fastening systems). Their structural feature is single-point fixing, relying solely on a single high-strength spike to secure the gauge block to the sleeper. Lateral displacement of the gauge block is indirectly limited by elastic clips that press against the rail. This design is simple, easy to install, and suitable for ordinary lines.

[0004] However, under the influence of high axle loads and high-frequency lateral forces (such as in curved sections and turnout areas) on high-speed railways, single-spiked rail fixing plates have the following problems: the rail spikes are prone to loosening, long-term lateral vibration leads to a decrease in preload, requiring frequent re-tightening. The plate may shift, resulting in insufficient lateral stiffness of the single-point fixing, which can easily lead to gauge expansion; and fatigue life is short, as both the rail spikes and the plate are prone to cracking under alternating stress.

[0005] To overcome the above problems, shoulders are installed on the sleepers. These shoulders block the gauge plates, thereby improving resistance to lateral displacement. However, in scenarios with small radii, such as within stations or tunnels, there are no shoulders on the sleepers, and the above problems still exist.

[0006] Therefore, the applicant proposes a new type of gauge baffle that is not limited by the scene, can effectively improve the resistance to lateral displacement, reduce track spike loosening, extend service life, and provide a new idea for the optimization of high-speed railway track structure.

[0011] The installation area of ​​the elastic clip has an upward-protruding mounting platform. The middle left side of the mounting platform has a T-bolt mounting hole, and the right side of the mounting platform has an elastic clip placement groove.

[0012] Furthermore, the bottom of the T-bolt mounting hole is provided with a T-groove that mates with the T-shaped platform of the T-bolt hole.

[0013] Furthermore, the spike hole is an elongated hole extending in the left-right direction.
