INSULATION TYPE RAIL-MOUNTAIN-CROSSING UNIT

Japanese Patent JP2015205740

A

PROBLEM TO BE SOLVED: To provide an insulation type rail-mountain-crossing unit capable of surely preventing erroneous detection of an existing rail, by securing an insulation property, without receiving influence of dust of including rainwater and iron powder.SOLUTION: An insulation type rail-mountain-crossing unit comprises a travel girder 3 having a travel passage and support legs 4 installed in both end parts of this travel girder 3 and supporting the travel girder 3, and an insulator for electrically insulating both is interposed between the travel girder 3 and the support legs 4. An interposing structure of the insulator fastens those bottom plate 22b and upper surface plate 15 by a fastener 25 in a state of interposing an insulation collar 31 and an insulation washer 32 between the bottom plate 22b and the upper surface plate 15, by arranging an insulation plate 30 between the bottom plate 22b being an insulator installing part on the travel girder 3 side and the upper surface plate 15 being an insulator installing part on the support legs 4 side.
