Description
【考案の詳細な説明】 ［産業上の利用分野］ 本考案は上方のホイストでケージを昇降させる昇降機
に於いて、ケージの落下を防止する装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for preventing a cage from falling in an elevator for raising and lowering the cage by an upper hoist.
［従来の技術］ 吹抜タテ孔を備えた高層構築物に於いて、このタテ孔

の要望があった。[Prior Art] In a high-rise building with a vertical blow hole, there is a great demand for a temporary elevator that uses this vertical hole to carry in and remove materials, but it has been conventionally known as a fall prevention device for it. Most of them have a structure in which most of them are actuated by a fall acceleration, as in Japanese Patent Laid-Open No. 50-146049. There was a time lag before the fall was stopped, so it was structurally unsuitable as a temporary device. There was a demand for a simpler structure that works properly.
［課題解決の手段］ ケージは通常対角線方向に渡しかけたロープによっ
て、ホイストのフックに係止されている。[Means for Solving the Problem] Usually, the cage is locked to the hook of the hoist by a rope extending in a diagonal direction.

瞬、このレバ吊下ロープも同時に破断するようにしてお
く。The cage is dropped by breaking the rope,
The cage is normally guided by a guide rail standing in the vertical hole to move up and down in order to avoid lateral swaying during raising and lowering. This guide rail will be used, and a swing lever is pivotally attached to the cage at the center. One end surface of the swing lever is formed so as to be able to dig into the surface of the guide rail, and the attached spring constantly urges rotation in the digging direction. The other end of the swing lever is hung from a hook via a thin rope against the spring. This suspension rope shall be appropriately weak, and the lever suspension rope shall be broken at the same time as the cage suspension rope is broken.
ケージ吊下ロープは対角線状に渡しかけてあるため、
その破断箇所によっては、レバ吊下ロープが破断せずゆ
るむ場合もあるが、ばねの作用で同様にくい込み作用が
起こる。Since the cage suspension rope is laid across diagonally,
Depending on the breakage point, the lever suspension rope may loosen without breaking, but the action of the spring causes the same difficult jamming action.

ものとしてある。[Examples] The drawings will be described. A hoist drum D is attached to the upper portion of the blow-through vertical hole, and a hook H hangs down. The cage C is provided with a rope R extending diagonally from the upper surface, and is suspended by a hook H with the rope R. The guide rail 1 has an I shape and is vertically fixed to the vertical hole. The pair of outer arms 2 project from one side surface of the cage in the guide rail direction, and are provided with rollers 3 at their tips, respectively, and hold the guide rails. A pair of inner arms 4 is located between the outer arms and also projects from the surface of the cage and has a shaft 5 at its tip. The swing lever 6 is pivotally attached to the shaft 5 at the central portion, one end thereof is hung from the hook H via the rope 7, and the other end thereof faces the lower abdominal surface of the guide rail. Teeth 6a are provided at this end so as to be able to bite into the same abdominal surface. The spring 8 is attached to the inner arm, and always urges the swing lever to turn in the direction of the bite. The rope 7 is appropriately weaker than the rope R.
本考案は以上のように構成される。従って対角線方向

み、ケージの落下を防止する。The present invention is constructed as described above. Therefore, no matter which one of the diagonal ropes R is broken, the cage is supported by the remaining rope and tilts, causing the rope 7 to break or sag. As a result, the rocking lever bites into the guide rail and prevents the cage from falling.
［効果］ 既設の昇降機へ揺動レバを附設し、これをロープ７で
吊下げるだけでたりる。ロープＲの破断に即時対応して
落下を防止する。[Effect] A swing lever can be attached to the existing elevator, and this can be suspended by the rope 7. Immediately respond to the breakage of the rope R to prevent it from falling
