図２は図１のエレベータかご自重測定装置８を示すブロック図である。エレベータかご自重測定装置８は、それぞれの機械台１に設けられ、巻上機台３を持ち上げる一対のジャッキ装置８１と、それぞれのジャッキ装置８１に設けられ、ジャッキ装置８１に支持される測定対象物の重量を測定する一対の重量測定装置８２と、それぞれの重量測定装置８２の測定結果を用いて、かご６の自重を算出するかご自重算出装置８３と、それぞれのジャッキ装置８１による巻上機台３の持上げ量を測定する持上げ量測定装置８４と、持上げ量測定装置８４の測定結果を用いて、それぞれの防振ゴム２について交換する必要があるか否かを判定する防振ゴム交換判定装置８５と、かご自重算出装置８３の算出結果および防振ゴム交換判定装置８５の判定結果を表示する表示装置８６とを備えている。   FIG. 2 is a block diagram showing the elevator car self-weight measuring device 8 of FIG. The elevator car self-weight measuring device 8 is provided on each machine base 1 and a pair of jack devices 81 for lifting the hoisting machine base 3, and a measurement object provided on each jack device 81 and supported by the jack device 81. A pair of weight measuring devices 82 for measuring the weight of the car, a car weight calculating device 83 for calculating the own weight of the car 6 using the measurement results of the respective weight measuring devices 82, and a hoisting machine base by each jack device 81 3 is used to determine whether or not each of the anti-vibration rubbers 2 needs to be replaced using the measurement result of the lifting amount measurement unit 84. 85, and a display device 86 for displaying the calculation result of the car weight calculation device 83 and the determination result of the vibration isolating rubber replacement determination device 85.

ジャッキ装置８１に支持される測定対象物としては、巻上機台３、巻上機４、ロープ５、かご６およびつり合い重り７が含まれている。巻上機台３、巻上機４、ロープ５およびつり合い重り７のそれぞれの重量は、既知となっている。エレベータをリニューアルする場合には、新たな測定対象物の中でかご６以外のものの各重量がかご自重算出装置８３に入力される。これにより、エレベータのリニューアル後に、かご６の自重を算出することができる。なお、測定対象物としては、これらに限らず、例えば、かご６とエレベータ制御盤とを繋ぐ制御ケーブル、巻上機４に供給される油などを含めてもよい。これらの重量も、既知となっている。   The measuring objects supported by the jack device 81 include a hoisting machine base 3, a hoisting machine 4, a rope 5, a car 6, and a counterweight 7. The respective weights of the hoisting machine base 3, the hoisting machine 4, the rope 5 and the counterweight 7 are known. When the elevator is renewed, the weights of the new measurement objects other than the car 6 are input to the car weight calculation device 83. Thereby, the own weight of the car 6 can be calculated after renewal of the elevator. The measurement object is not limited to these, and may include, for example, a control cable that connects the car 6 and the elevator control panel, oil supplied to the hoisting machine 4, and the like. These weights are also known.

重量測定装置８２は、例えば、ロードセルから構成される。かご自重算出装置８３には、かご６を除いた測定対象物の重量の情報が記憶されている。かご自重算出装置８３は、それぞれの重量測定装置８２の測定結果を取得して、測定対象物の重量の値から、記憶されているかご６を除いた測定対象物の重量の値を減算することによって、かご６の自重を算出する。   The weight measuring device 82 is composed of, for example, a load cell. The car weight calculation device 83 stores information on the weight of the measurement object excluding the car 6. The car weight calculation device 83 acquires the measurement result of each weight measurement device 82 and subtracts the stored weight value of the measurement object excluding the stored car 6 from the weight value of the measurement object. The weight of the car 6 is calculated by

防振ゴム２は、測定対象物の重量が加えられている場合に、高さ方向の寸法が小さくなるように変形する。また、防振ゴム２は、測定対象物の重量が取り除かれた場合に、高さ方向の寸法が元の値となるように変形する。防振ゴム２の劣化が進行すると、防振ゴム２は、測定対象物の重量が取り除かれても、高さ方向の寸法が元の値よりも小さくなる。防振ゴム交換判定装置８５には、劣化が進行して交換が必要となる場合の防振ゴム２の高さ方向の寸法が記憶されている。防振ゴム交換判定装置８５は、持上げ量測定装置８４の測定結果と、記憶されている交換が必要となる場合の防振ゴム２の高さ方向の寸法とを用いて、防振ゴム２を交換する必要があるか否かを判定する。持上げ量測定装置８４は、それぞれの防振ゴム２について、交換する必要があるか否かを判定する。なお、防振ゴム交換判定装置８５は、持上げ量測定装置８４の測定結果を用いずに、それぞれの重量測定装置８２の測定結果を用いて、それぞれの重量測定装置８２に作用する加重の偏重によって、防振ゴム２を交換する必要があるか否かを判定してもよい。   The anti-vibration rubber 2 is deformed so that the dimension in the height direction becomes small when the weight of the measurement object is added. Further, the anti-vibration rubber 2 is deformed so that the dimension in the height direction becomes the original value when the weight of the measurement object is removed. When deterioration of the vibration isolating rubber 2 proceeds, the dimension of the vibration isolating rubber 2 becomes smaller than the original value even if the weight of the measurement object is removed. The anti-vibration rubber replacement determination device 85 stores the dimension in the height direction of the anti-vibration rubber 2 when the deterioration has progressed and needs to be replaced. The anti-vibration rubber replacement determination device 85 uses the measurement result of the lifting amount measuring device 84 and the height-direction dimension of the anti-vibration rubber 2 when the exchange is necessary. Determine if it needs to be replaced. The lifting amount measuring device 84 determines whether or not each anti-vibration rubber 2 needs to be replaced. The anti-vibration rubber replacement determination device 85 does not use the measurement result of the lifting amount measurement device 84, but uses the measurement result of each weight measurement device 82, and by the weight of the weight acting on each weight measurement device 82. It may be determined whether or not the anti-vibration rubber 2 needs to be replaced.
