An adjustable guard rail assembly is provided for use with a running rail and is made up of a plurality of spaced base plates having one end extending beneath the running rail, brace means fixed to each base plate adjacent the other end, a guard rail supported on said spaced base plates and abutting said braces, fastening means extending through said brace and guard rail and interchangeable spacer means on said fastening means interchangeable from one side of the guard rail to the other whereby the position of said guard rail with respect to the brace may be changed.
摘要:
A sensor for detecting electrical current on an insulating element of a rail system, comprising: at least one electrically conductive lead or wire for attaching the sensor to the insulating element; an energy harvester for harvesting electric current transmitted from the insulating element to the energy harvester via the lead; a microprocessor circuit including a capacitor wherein the capacitor is charged by energy harvested by the energy harvester; and a transmitter for wirelessly transmitting RF signals indicative of the detected current; wherein the microprocessor and transmitter are powered by the energy from the capacitor.
摘要:
A bonded fastener for a railway rail comprising: top and bottom generally horizontal plates bonded and separated by an insulating material wherein the top plate defines a rail bed; a plurality of clip housings wherein each clip housing houses part of a hold-down clip for attaching the rail to the bonded fastener; a plurality of anchor assembly areas wherein each anchor assembly area defines an opening through the bonded fastener for receiving an attachment device for attaching the fastener to a supporting surface; and one or more generally vertical barriers comprising part of the bonded fastener. Further, a first generally horizontal barrier may extend from the bonded fastener underneath each of the clip housings, and a second generally horizontal barrier may extend from the rail bed underneath the rail on each side of the bonded fastener.
摘要:
A conductor rail assembly for use in transit rail transportation systems to transmit electrical power to rail cars comprising a first and second support sections preferably of aluminum to give the rail assembly its rail-shape and conductivity and a cap section preferably of stainless steel to provide a wear resistant surface to prevent damaging of the conductor rail by collector shoes that extend from rail cars and run on the conductor rail. The first support section has a rib and the second support section has a concavity. In the assembly, the rib of the first support member preferably is disposed within the concavity of the second support member, portions of both support members preferably are friction fit or compression fit within the cap and a friction stir weld preferably is disposed on the bottom of the assembly along a joint between the first and second support sections.
