【発明の詳細な説明】 〔産業上の利用分野〕 本発明は非常停止装置の動作試験を行う時に乗かごを
下降させて非常停止装置の動作試験を行う油圧エレベー
タの動作試験運転装置に関する。Description: TECHNICAL FIELD The present invention relates to a hydraulic elevator operation test operation device for lowering a car to perform an operation test of an emergency stop device when performing an operation test of the emergency stop device.
一般に油圧エレベータにあつては、シリンダ内に圧油

よつて、シリンダに設けられるプランジヤが上下に移動
し、このプランジヤの上下動がロープを介して乗かごに
伝達され、その結果、乗かごがガイドレールに沿つて昇
降路内を昇降するようになつている。また、このような
油圧エレベータでは、乗かごの昇降時にロープが弛緩す

ごをガイドレールに固定して、乗かごを停止させる非常
停止装置が乗かごに設けられている。そして、乗かごの
安全運行を図るために、上記の非常停止装置が正常に作
動するかどうかを定期的に試験する必要がある。Generally, in the case of a hydraulic elevator, plunger provided in the cylinder moves up and down due to inflow of pressure oil into the cylinder and outflow of pressure oil from the cylinder, and the vertical movement of the plunger is controlled by a rope. , So that the car moves up and down the hoistway along the guide rails. Also, in such a hydraulic elevator, if an abnormal situation such as a loosened rope occurs when the car is raised or lowered, the car will suddenly fall in the hoistway. An emergency stop device fixed to the guide rail and stopping the car is provided in the car. Then, in order to ensure safe operation of the car, it is necessary to periodically test whether the above emergency stop device operates normally.

ンジヤを下降させて、このときの乗かごの降下状況によ
り非常停止位置の作動が正常が否かを判定するようにな
つている。Conventionally, when performing an operation test of such an emergency stop device, another worker in the car intermittently operates the lowering operation button at the instruction of a worker who has entered the pit at the bottom of the hoistway. By pressing the car, the car is lowered gradually, and the car is brought into contact with a support member made of a jack, a square bar and the like arranged on the pit floor. Next, when the jump plunger is raised in a state where the car is supported by the support member, the car floats and the ropes are relaxed, so that the emergency stop position is operated. Therefore, the worker in the pit operates the jack in the opposite direction, that is, lowers the jack plunger, and determines whether the operation of the emergency stop position is normal or not based on the car descent condition at this time. I have.
ところで、上述した従来技術にあつては、非常停止装

材に急激に当たつたり、その衝撃により支え部材が斜め
に傾くことがあり、安全かつ確実に支え部材上に乗かご
を当接できないという問題があつた。By the way, in the above-described conventional technology, when an operator in the car presses the lowering operation button intermittently during the operation test of the emergency stop device, the pressing operation is repeatedly performed in a fixed pattern. Because of the difficulty in carrying the car, the descending speed and the descending distance of the car vary, and as a result, the worker supporting the supporting members in the pit cannot predict the descending speed and the descending distance. There is a problem that the support member may suddenly hit the support member, or the support member may be inclined obliquely due to the impact, so that the car cannot be safely and reliably abutted on the support member.
本発明はこのような従来技術における実情に鑑みてな
されたもので、その目的は、非常停止装置の作動試験時

において、上記下降運転指令スイツチが投入されている
時に、上記運転指令の出力を一定周期で断続させる断続
信号を出力する断続信号出力装置を設けたものである。In order to achieve this object, the present invention includes a descent operation command switch that outputs an operation command to lower the car of the hydraulic elevator when operated when performing an operation test of the emergency stop device, In a hydraulic elevator operation test driving device that performs an operation test of the emergency stop device by lowering the car until it comes into contact with the supporting member by operating the switch, when the lowering operation command switch is turned on, An intermittent signal output device for outputting an intermittent signal for intermittently outputting an output is provided.
