SUPPORT FRAME SYSTEM OF ELEVATOR CAGE

摘要

A support frame system of a elevator cage includes a first support frame and a secondary support frame outside the cage. The first support frame is composed of two first columns respectively positioned at the left side and the right side of the cage, a first upper beam and a first lower beam respectively positioned on the top of the cage and under the cage. The secondary support frame includes a secondary upper beam parallel to the first upper beam, and its two ends are fixed to the first upper beam. Two return pulleys are installed between the first upper beam and the secondary upper beam. Because there is some distance between two return pulleys and the upper beams, the two return pulleys may be kept away from the guide shoe and be provided at the edge of the cage. According to the present invention, the system has the following advantages. Because two return pulleys are installed between the first upper beam and the secondary upper beam and are kept away from the guide shoe, the system achieves that the traction machine is installed outside the vertical projection of the maintenance space on the top of the cage. In other words, the traction machine can be installed to keep away from the maintenance space on the top of the cage. At the same time, the guide rail can be kept away from the first columns and close to the cage wall, so as to reduce the space needed when the elevator runs.
