Description of the Related Art The structure of a conventional escalator speed detecting device is such that a detecting device such as a rotary encoder is attached to an input shaft of a speed reducer as disclosed in Japanese Patent Laid-Open No. 63-210439. A device that detects the traveling speed of an escalator from the input shaft speed is generally known.

復旧作業が非常に困難であった。Since the speed detection device of the escalator has a detection device such as a rotary encoder directly fixed to the input shaft of the speed reducer, when the function of the speed detection device is inspected by an actual machine, Since it is necessary to rotate the input shaft of the speed reducer at a variable speed, it is necessary to supply an inverter power supply to the motor to change the input shaft speed of the speed reducer. For this reason, the inverter power supply must be brought near the motor during the inspection, which is inconvenient for the inspection work. Furthermore, in order to ensure the safety of workers during inspection and protect the functions of the escalator body, it is necessary to prevent the steps of the escalator from moving even when the input shaft of the reducer is rotated.
Since the drive chain has to be removed, the preparatory work for performing the function inspection of the speed detection device and the recovery work after the inspection are very difficult.

う、作業性の向上を図ったものである。A rotary plate for a speed detection device is provided on an input shaft of a speed reducer of a drive device including a drive motor and a speed reducer in a machine room of a passenger conveyor. Normally, it rotates with the input shaft of the speed reducer to detect the traveling speed of the passenger conveyor, and when performing the function inspection of the speed detection device, the rotation plate is reduced with bolts so that it can be rotated by itself. By fixing to the input shaft of No. 3, the function of the speed detecting device can be inspected by the rotation plate unit rotation test, and the workability is improved with the function test of the escalator speed detecting device.

の機能検査に伴う作業性を向上することができる。[Operation] By rotating the rotating plate, which is the speed detecting portion of the escalator speed detecting device, to the input shaft of the speed reducer and fixing it with bolts, it is normally rotated with the input shaft of the speed reducer. When the speed of the passenger conveyor is detected and the function of the speed detection device is tested, it is released from the input shaft of the speed reducer by simply removing the bolts, so it is not necessary to supply the inverter power supply. Since the rotation test can be performed on the rotating plate alone, the workability associated with the function inspection of the speed detecting device can be improved.

いる。FIG. 1 shows the structure of a drive unit consisting of a motor 1 and a speed reducer 2, in which a rotary plate 4 which is a detecting portion of a speed detecting device is fixed to the tip of an input shaft 3 of the speed reducer. . As shown in FIG. 2, the rotary plate 4 is normally supported by a boss 5 fitted to an input shaft 3 of a speed reducer having a tapered tip end from the outside and fixed by bolts 6. Therefore, it operates as a detection unit of a speed detection device using the rotation speed of the input shaft 3 of the speed reducer. On the other hand, as shown in FIG. 3, when the bolt 6 is removed, the rotary plate 4 is released from the input shaft 3 of the speed reducer and can be rotated by itself.
Further, since the hollow tube 7 made of a self-lubricating material is fitted and axially supported on the inner peripheral portion of the rotary plate 4, it is possible to make a very smooth single rotation. Further, a ring groove is formed on the input shaft 3 of the speed reducer, and a retaining ring 8 is provided in this groove to prevent the rotary plate 4 from coming off the input shaft 3 of the speed reducer when rotating alone. A liner 9 is provided between the retaining ring 8 and the rotary plate 4 so that the side surface of the rotary boss 5 and the side surface of the boss 5 come into contact with each other with an appropriate force, and the runout of the rotary plate 4 during a single rotation is suppressed. . With these, the function inspection of the speed detecting device by the single rotation test of the rotary plate 4 is enabled.
