The invention provides a non-contact breakage detection device for a comb plate, which is not easily influenced by dirt of a ladder plate of a passenger conveyor. A damage detection device (8) is provided with an anti-slip section (12), a plurality of electrode pairs (139), a measurement section (16), and a detection section (17). An anti-slip part (12) made of an insulator is mounted on the upper surface of the step plate (6). The anti-slip section (12) has a plurality of groove sections (19) arranged side by side in the left-right direction so as to be parallel to each other in the front-back direction. The pair of electrodes (13) is disposed on the groove wall in the groove portion (19) so as to face each other in the left-right direction. The measuring unit (16) measures the capacitance between the electrode pairs (13). The detection unit (17) detects damage to the comb teeth (11) passing through the groove portion (19) when the amount of change in capacitance measured with respect to the electrode pair (13) disposed in any one of the groove portions (19) while the step plate (6) passes through the comb plate (4) is less than a preset threshold value.
提供不易受到乘客输送机的梯板的污垢的影响的非接触式的梳齿板的破损检测装置。破损检测装置(8)具备防滑部(12)、多个电极对(139)、测量部(16)、以及检测部(17)。由绝缘体构成的防滑部(12)安装于梯板(6)的上表面。防滑部(12)具有以沿着前后方向相互平行的方式在左右方向上排列设置的多个槽部(19)。电极对(13)在槽部(19)以在左右方向上相互相向的方式配置于槽壁。测量部(16)测量各个电极对(13)之间的静电电容。检测部(17)在梯板(6)通过梳齿板(4)的期间关于配置在任意一个槽部(19)的电极对(13)测量的静电电容的变化量小于预先设定的阈值时,检测通过该槽部(19)的梳齿(11)的破损。
