た場合を検出する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator system, and particularly to a device for detecting when a balance weight moving up and down along a guide rail is separated from the guide rail.

は機械的に検出するものがある。The balance weight of an elevator generally moves up while engaging a pair of guide rails provided on both sides via guides. When the guide rail is subjected to vibration from the ground, etc., the excitation force may cause the guide rail to bend and become detached from the guide rail. In other words, since the counterweight separates from the guide rail, it is necessary to prevent collateral dangers such as collision with a car that is being raised or lowered. To detect this, a wire can be installed vertically in parallel to the guide rail, or a wire can be installed to surround the counterweight along the entire length of the hoistway, and the wire and counterweight can be connected to each other. There are some that are detected electrically or mechanically.

以F、本発明の実施例を第1図により説明する。 Hereinafter, an embodiment of the present invention will be described with reference to FIG.
つり曾いおもりlはガイド4を介して両側に設けたガイ
ドレール3に案内されて昇降する。The heavy weight l is guided by guide rails 3 provided on both sides via a guide 4 to move up and down.

導電する。2は吊りロープ。The contactor 10 is electrically conductively fixed to the guide rails on both sides, and is connected to an electric signal detector 11 and a power source 15. Further, as shown in FIG. 2, the contact body 12 is fixed to a counterweight K and a balance weight L so that the contact 13 urged by the elastic body 14 presses against the guide rail surface, and
Conduct electricity. 2 is a hanging rope.
こtlらは、第3図に示す電気回路を構成する。These constitute the electric circuit shown in FIG.

+ となる。このML流は、つり合いおもりの行程に比
例したものとなり、第4図に示すように、下階になるに
つれガイドレールの抵抗により小さくなる特性をもつ。In other words, between a and 1) there is a resistance R1 that balances each other, and between c and 6 there is a resistance 2 between the guide rails on both sides. In general, R1 has a sufficiently small resistance value compared to R2, and the current I flowing through the circuit in Figure 3 is the current I flowing between a and 5 when the counterweight is not detached.
+. This ML flow is proportional to the stroke of the counterweight, and as shown in FIG. 4, has a characteristic that it decreases as the floor gets lower due to the resistance of the guide rail.
一方、つり合いおもりが離脱するとicL流はC−6間
を流れる。この時の抵抗R2は大きいので電流は工2と
なり、11に比して十分に小さな値となる。On the other hand, when the counterweight is removed, the icL flow flows between C-6. Since the resistance R2 at this time is large, the current is 2, which is a sufficiently small value compared to 11.
この差を検出計11により眠気出力信号として検出する

、つり合いおもりが離脱した場合は、ただちに、その運
転を停止することができる。By detecting this difference as a drowsiness output signal by the detector 11, it is sent to the elevator operation control system (not shown), and when the counterweight is detached, the operation can be immediately stopped.
本発明によれば、あらたに昇降路スペースを必要とせず

隣的なエレベータ−の脱レール検出装置が得られる。According to the present invention, there is no need for additional hoistway space, and there is no need to install equipment over the entire length of the hoistway, and an adjacent elevator derailment detection device can be obtained.
