Abstract

PURPOSE:To permit the measurement of brush wear amount during operation and to facilitate maintenance and inspection by movably arranging a contactless switch applied an insulating layer with predetermined thickness on the upper part of pressure arms by providing predetermined distance. CONSTITUTION:A detecting alarm device 10 consisting of a contactless switch 12 applied an insulating layer 11 with predetermined thickness l1 at a position providing predetermined distance l from the head sections of pressure arms 7a, 7b is installed on a locker 5 and the switch 12 is permitted to move by gears 13, 14. A gear box 15 installed on the locker 5 contains the gears 13, 14 and the switch 12 and a handle 16 pivoting the switch 12 are mounted and provided on the tip of the gear 14 and the gear 13 respectively. The gear 13 rotates by pivoting the handle 16 and the gear 14 connected to the switch 12 moves up and down between a-a by accompanying with gear rotation. In this way, the measurement of brush wear amount is permitted even during operation and maintenance and inspection can easily be performed.
