Detailed Description

The technical solutions of the embodiments of the present invention are explained and explained below with reference to the drawings of the embodiments of the present invention, but the embodiments described below are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in fig. 1 and 2, the elevator traveling cable safety protection device is characterized in that an elevator is controlled by a control cabinet 6, the control cabinet 6 is installed on the top of an elevator car 5, and the control cabinet 6 is connected with a traveling cable 3. In addition, reference can be made to the prior art for other structures of the elevator, including the machine room control cabinet 1, the counterweight 7, etc. The safety protection device for the elevator travelling cable comprises a device seat 8, wherein the device seat 8 is provided with a travelling cable moving channel through which the travelling cable 3 can move, a trigger sensor triggered by an outer sleeve falling off from the travelling cable is installed on the side of the travelling cable moving channel of the device seat 8, and the trigger sensor is connected with the control cabinet 6.
