Description
据付や調整を行った初期の状態では、図１に示すように、第２腕部材４０はばね４１によってストッパ４２に接しており、スイッチ４３は非作動の状態にある。
そして、長年の使用によりガバナロープ９が伸びてくると、テンションプーリ８が下降し、腕部材３２は軸３２ａを中心にして反時計方向に回転するが、第２腕部材４０はストッパ４２に接したままであるため、スイッチ４３は非作動のままである。
The installation and adjustment of the initial Been state, as shown in FIG. 1, the second arm member 4 0 is in contact with the stopper 42 by the spring 41, the switch 43 is in the unactuated.
When the governor rope 9 is extended due to long-term use, the tension pulley 8 is lowered, and the arm member 32 rotates counterclockwise about the shaft 32a, but the second arm member 40 contacts the stopper 42. As a result, the switch 43 remains inactive.
更に、第２腕部材６０と腕部材５１との間にスイッチを設置して、歯型部材３１の回転を検出するようにすれば、テンションプーリ８が所定以上下降したことを検出することもできる。
前記実施の形態では、ラチェット機構３５は、第２腕部材６０側に歯型部材３１、腕部材５１側に爪部材３３を配置しているが、逆に第２腕部材６０側に爪部材、腕部材５１側に歯型部材を配置することもできる。
Furthermore, if a switch is installed between the second arm member 60 and the arm member 51 to detect the rotation of the tooth-shaped member 31, it is possible to detect that the tension pulley 8 has been lowered by a predetermined amount or more. .
In the above embodiment, the ratchet mechanism 35 has the tooth type member 31 on the second arm member 60 side and the claw member 33 on the arm member 51 side, but conversely on the second arm member 60 side, A tooth-shaped member can be disposed on the arm member 51 side.
Claims (1)
The elevator apparatus according to any one of claims 1 to 3 , wherein a detection device that detects a downward movement of the tension pulley is provided in the descending allowance device.
