Document Type and Number:
Japanese Patent JP2000152404
Kind Code:
A
Abstract:

To easily remove the snow without danger of maintenance person and heating energy, by providing a now removing jig provided to one end of a pipe member coupled with a flexible body, and a handle to drive, in the pipe axis direction, the flexible body provided toward the other end of the pipe member.

A fixing jig 3 is provided between the rods of a pantagraph 16 and the fixing jig 3 is fixed to the rods of pantagraph. Accordingly, a snow removing jig 2 is set on a pantagraph power receiving part 17. Under this condition, when a snow removing handle 7 is lifted, a snow removing jig 2 moves on the pantagraph power receiving part 17 to remove the snow. After the snow is removed, a fixing lever 4 is manipulated to loosen the fixing jig to remove it from the pantagraph and the maintenance work for the next pantagraph is started. As explained above, the snow can be removed only by the manipulation on the ground. Moreover, even if the snow removing jig 2 or the like is in contact with the catenary, it is possible to prevent electrical shock, owing to the electrical insulating function of the pipe member 1 and an internal rod or internal flexible body 9 and a coupling part material.
