Detailed ways

The present invention can be explained in more detail by the following examples, and the present invention is not limited to the following examples;

First of all, it should be noted that the positional relationship adopted in the writing of the present invention is based on the drawings in the specification.

A shaft elevator with double safety devices described in conjunction with accompanying drawing 1 includes a steel wire rope 2, a car 3, a driven friction plate 4, an emergency button 5, an active friction plate 6, an upper airbag launching device 7, an upper airbag 8 and The lower airbag 9, the driven friction plates 4 are strip-shaped structures, the driven friction plates 4 are set to four, and the four driven friction plates 4 are respectively arranged on both sides of the left and right sides of the ladder shaft 1, and a car 3 is provided in the ladder shaft 1 , the car 3 is provided with handrails, the inner wall of the car 3 is provided with a plane mirror for finishing the appearance, the top of the car 3 is provided with a ventilation system, if necessary, a fresh air system can be set on the top of the car 3 , an elevator control panel is provided on the inner wall of the car 3. It should be noted that, since the control panel, ventilation system, fresh air system, etc. are not the focus of the protection of the present invention, they will not be repeated here.
