[0006] However, the safety switch mounting position adjustment device described in Patent Document 1 cannot check the operating state of the link mechanism arranged to turn on the safety switch on the opposite side where the safety switch and the lever can be adjusted.
Therefore, in the case of fixing the link fulcrum portion as the link fulcrum of the above-mentioned link mechanism, even if slack occurs in the drive chain and the drive chain is disconnected, the above-mentioned link mechanism does not operate and the safety switch cannot be turned on. possibility of
[0007] Therefore, in the inspection of the existing safety device, when the slide is lowered in order to confirm the operating state of the link mechanism, it is necessary to remove the drive chain from the sprocket, which wastes inspection time and man-hours.

The invention provides an escalator safety device abnormality detection device and an abnormity detection method, which can be used to carry out safety switch check, position adjustment, and motion state of a checking mechanism without dismounting a driving chain from a driving wheel. The safety device abnormity detection device 16 used to detect the abnormal state of the safety device of the escalator 100 comprises inserting holes 34,36 used as connecting fulcrums of a connecting rod mechanism 30, an inserting part 19 used for temporary fixing the connecting rod mechanism 30, and a bolt head 18 disposed on one end of the inserting part 19, a connecting rod limiting part 17 disposed on the bolt head 18. The connecting rod limiting part 17 is in the shape of a fan column shape, and the central angle of the fan shape is smaller than 180degrees, and according to the inserting depth of the inserting part 19 with respect to the inserting holes 34,36, the corner part 17A is contacted with the driving chain 4.
Description
Technical field [0001] The present invention relates to a safety device abnormality detection device and a safety device abnormality detection method for detecting abnormality of a safety device installed on an escalator. Background technique [0002] All along, handrails and steps held by passengers have been installed on escalators. These handrails and steps are driven by a step drive sprocket and a drive chain, which is connected to the sprocket of the drive device. In addition, a safety device that detects slack and disconnection of the drive chain and stops the escalator based on the detection result is provided on the drive chain. The safety device is provided with a safety switch operated by the sliding shoes arranged on the drive chain and a contact metal piece connected by a link mechanism, and the safety device stops the escalator when the safety switch operates. [0003] The position adjustment of the above-mentioned safety switch is performed during the inspection of ...
