Description
- The present disclosure is directed to a railway and, more particularly, to a railway having a vibration-dampened detector tie.
- A railway is a permanent travel path for a rail vehicle. A typical railway includes a connected lattice structure consisting of ties that are at least partially buried within ballast, parallel rails that are supported by the ties in a spaced-apart configuration, and fasteners that bind the rails to the ties. Historically, the ties have been fabricated from wood, although some modern ties are also fabricated from concrete, steel, or synthetic material.
- Modern railways can also be equipped with detectors positioned to detect conditions of the rails and/or the rail vehicles as they travel along the rails. In some instances, the detectors are connected to the ties at locations near or between the rails, One problem with connecting the detectors to the ties, however, has been vibrations induced within the ties as the rail vehicles travel along the rails. These vibrations, if left unchecked, can cause damage to the detectors. The vibrations are also manifest in the form of noise, which can he a nuisance in some applications.
- One attempt to reduce vibration within a railway is disclosed in JP Patent No. 07216801 that issued to Akira et, al (“the '801 patent”). Specifically, the '801 patent discloses a multi-layer emulsion resin composition disposed between a rail and each tie of the railway. The composition is intended to dampen sound caused by a train traveling on the railway.
- Although perhaps somewhat effective at reducing noise, the resin composition of the '801 patent may be less than optimal. In particular, the resin composition may be expensive and difficult to apply to the railway. Further, applying the composition to all ties within a given railway may be impractical. In addition, the composition of the '801 patent is not designed for use with detector ties and, accordingly, may not adequately protect any associated detectors,
- The railway and detector tie of the present disclosure are directed at solving one or more of the problems set forth above and/or other problems in the art.
- In one aspect, the disclosure is related to a detector tie for a railway. The detector tie may include a tie base, and a detector operatively coupled to the tie base. The detector tie may also include a vibration damper connected to a least one of the tie base and the detector. The vibration damper may be configured to protect the at least one detector from vibrations induced within the railway.
- In another aspect, the disclosure is related to another detector tie. This detector tie may include a metallic tie base having a generally hollow enclosure, and at least one of a dragging equipment detector and an over temperature detector at least partially disposed within the generally hollow enclosure. The detector tie may also include a vibration coating applied to the metallic tie base. The vibration coating may have a thickness tuned to reduce a natural frequency within the at least one of the dragging equipment detector and the over temperature detector. The vibration coating may also be configured to inhibit oxidation of the tie base.
- In yet another aspect, the disclosure is related to a railway. The railway may include at least one rail, a plurality of non-detector ties configured to support the at least one rail, and a detector tie disposed between two of the plurality of non-detector ties. The detector tie may be configured to support the at least one rail, and have a tie base made from a material different than a material of the plurality of non-detector ties. The detector tie may also have a detector operatively coupled to the tie base, and a vibration damper connected to a least one of the tie base and the detector. The vibration damper may be configured to protect the detector from vibrations induced within the at least one rail. The railway may also include a plurality of fasteners configured to connect the at least one rail to each of the plurality of ties and to the detector tie.

In some embodiments, a seal (not shown) may be placed atopenings 32 to inhibit debris and/or moisture from passing arounddetectors 22 and enteringenclosure 26. -
Detector 22 may generically refer to any type of detection device (e.g., sensor, camera, probe, electrode, catalyst, etc.) used to generate signals indicative of an operational condition ofvehicle 10 and/orrails 14. For example, eachdetector 22 may be one of a dragging equipment detector configured to detect the presence of equipment dragging beneathvehicle 10, or an over-temperature detector configured to detect an elevated temperature of a wheel, bearing, or brake ofvehicle 10. Other types of detectors may also be utilized. in the disclosed embodiment, two dragging equipment detectors are utilized (e.g., at a location between rails 14) together with two over temperature detectors (e.g., at locations outside of rails 14). It is contemplated, however that a different number and/or combination of detectors could alternatively be connected to eachtie base 20, if desired.Detectors 22 may be removably (e.g., by way of fasteners) or permanently (e.g., by way of welding) connected totie base 20. The signals generated bydetectors 22 may be recorded, processed, and/or communicated to local or remote systems for use in detecting and diagnosing issues associated with operation ofvehicle 10 and/orrailway 12. -
Vibration damper 24 may be configured to protectdetectors 22 from damaging vibrations passing fromrails 14 throughtie base 20. In the disclosed embodiment,vibration damper 24 is an elastomeric coating applied to tiebase 20, For example,vibration damper 24 may be applied to an external surface of rail mounts 28, such that the transmission of vibrations fromrails 14 to tiebase 20 is reduced. Additionally or alternatively,vibration damper 24 may be applied atopenings 32, such that the transmission of vibrations fromtie base 20 intodetectors 22 is reduced. Additionally or alternatively,vibration damper 24 may be applied over a majority of an external surface oftie base 20, such that vibrations withintie base 20 may be absorbed by the coating. In some embodiments,vibration damper 24 may additionally or alternatively be applied to an interior of tie base 20 (e.g., on internal walls of enclosure 26). When applied externally,vibration damper 24 may further function to inhibit oxidation oftie base 20 and/or to sealdetectors 22 to tiebase 20. - A thickness and/or composition of
vibration damper 24 may be selected to tune out particular vibrations withintie base 20. That is, the thickness and/or composition of the coating may be selected to tune out or otherwise at least partially cancel vibrations having the propensity to damage detectors 22 (e.g., the natural frequencies of detectors 22). In some instances this thickness and/or composition ofvibration damper 24 may vary depending on the location of the coating ontie base 20. For example, the coating ofvibration damper 24 may have a thickness and/or composition on the external surfaces oftie base 20 that are different than the thickness and/or composition on the internal surfaces oftie base 20. It is also contemplated that the thickness and/or composition ofvibration damper 24 may vary depending on the type ofdetectors 22 connected to tiebase 20, if desired. - The disclosed detector tie and railway may be used in conjunction with any rail vehicle to monitor performance of the vehicle, and the disclosed detector tie may have extended use because

And by applyingvibration damper 24 toonly detector ties 16 a, the overall cost ofrailway 12 may be low. - It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed railway and detector tie without departing from the scope of the disclosure. Other embodiments of the seal will be apparent to those skilled in the art from consideration of the specification and practice of the railway and detector tie disclosed herein. For example, it is contemplated that
vibration damper 24 could alternatively be a stand-alone component, fabricated from a non-elastomeric material, and/or applied to a component other than tie base 20 (e.g., torails 14 and/or detectors 22), if desired. It is intended that the specification and examples be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims and their equivalents.
