Description

この発明は、おもりを積載するエレベータの釣合おもりのおもり枠に関する。   The present invention relates to a weight frame for a counterweight of an elevator on which a weight is loaded.

従来、互いに対向した一対の縦枠の上部にそれぞれ切り欠き部が形成されたエレベータの釣合おもりのおもり枠が知られている（例えば、特許文献１参照）。
上記構成のエレベータの釣合おもりのおもり枠では、おもり枠におもりを積込む、または積下ろす際に、この切り欠き部では、対向した縦枠間の開口部の幅の距離がおもりの長さよりも長いために、おもりを水平方向に移動しておもり枠におもりを積込む、または積下ろすことができる。 2. Description of the Related Art Conventionally, there is known a weight frame of an elevator counterweight in which a notch is formed in each upper part of a pair of vertical frames facing each other (see, for example, Patent Document 1).
In the weight frame of the counterweight of the elevator configured as described above, when the weight is loaded into or unloaded from the weight frame, the distance of the width of the opening between the opposed vertical frames is greater than the length of the weight at the notch. Because of its long length, the weight can be moved horizontally to load or unload the weight frame.

特開平８-１６９６６８号公報（図９）JP-A-8-169668 (FIG. 9)

しかしながら、上記構成のエレベータの釣合おもりのおもり枠では、切り欠き部の下側は、おもり枠の開口部の幅の長さがおもりの長さよりも短いため、斜めに傾けて積込む、または積み下ろし作業をせざるを得ず、そのため下記のような問題点があった。
イ．おもりを置く際、最後まで手を添えて静かに置かずに上から落とすように置いた場合に、おもりが破損する可能性がある。
ロ．おもりの長さが長いほど、おもりの傾斜角度を大きくしながら積込み、または積下ろしをする必要性があり、その作業性が悪い。 However, in the weight frame of the counterweight of the elevator configured as described above, the lower side of the notch portion is loaded obliquely, because the width of the opening of the weight frame is shorter than the length of the weight, or There was a problem as described below because of the unloading work.
A. When placing a weight, if you put it down and drop it from the top without putting it gently until the end, the weight may be damaged.
B. As the length of the weight is longer, it is necessary to load or unload while increasing the inclination angle of the weight, and the workability is worse.
