[0021] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0022] Among them, the same reference numerals in the drawings all refer to the same components.

[0023] Embodiment 1

[0024] As Figure 1-6 shown, it includes a circular chassis 1, a connection head 2 and a fall arrester 3. The fall arrester 3 rotates in the circular groove of the chassis 1 through a rotating track 4. Connecting grooves 11 are opened around the top of the annular surface of the chassis 1. A rotating hole 12 is opened in the center of the bottom end inside the chassis 1. A limiting triangular plate 13 is arranged on the inner wall of the chassis 1. An anti-derailment end 14 is arranged between every two connecting grooves 11. A turntable notch 15 is arranged between the anti-derailment end 14 and the connecting groove 11. The connection head 2 includes a fixed I-beam 21, and the fixed I-beam 21 is connected to the connecting groove 11. The rotating track 4 includes a movable I-beam 41. Arc-shaped rotating chassis 42 are fixedly arranged on both sides of the bottom of the movable I-beam 41. A central shaft hole 43 is penetrated through the center of the bottom of the movable I-beam 41. The fall arrester 3 includes a U-shaped sliding block 31. A connection lock 32 is arranged on the top of the U-shaped sliding block 31. The connection lock 32 is rotatably connected to the U-shaped sliding block 31 through a connection shaft

[0025] Furthermore, the fixed I-beam 21 is detachably connected to the connecting groove 11, and uniformly distributed connecting holes 211 are opened on the surface of the fixed I-beam 21.

[0026] The U-shaped sliding block 31 is respectively slidably connected to the tops of the movable I-beam 41 and the fixed I-beam 21.

[0027] A positioning hole 16 is arranged on one side of the rotating hole 12. A positioning screw hole 421 having the same size as the positioning hole 16 is penetrated through the surface of one of the arc-shaped rotating chassis 42. The positioning hole 16 and the positioning screw hole 421 are connected by a threaded pin 422.

[0028] A nut 431 is arranged inside the central shaft hole 43. A bolt 121 is penetrated through the bottom of the rotating hole 12. The bolt 121 is threadedly connected to the nut 431. The rotating track 4 is rotatably connected to the chassis 1 through the bolt 121.

[0029] The limiting triangular plate 13 limits the rotation angle of the rotating track 4.

[0030] Specifically, during installation, the U-shaped sliding block 31 is slid to the top surface of the movable I-beam 41. Then, the nut 431 is placed inside the central shaft hole 43, and the rotating track 4 is inserted into the chassis 1. Next, the bolt 121 is passed upward through the bottom of the rotating hole 12 to be connected to the nut 431 inside the central shaft hole 43. At this time, the rotating track 4 can rotate around the bolt 12 as the axis. By rotating the movable I-beam 41, it is aligned with the fixed I-beam 21 on one side of the anti-falling device 3. Then, the anti-falling device 3 is dragged so that the U-shaped sliding block 31 slides from the top surface of the movable I-beam 41 to the surface of the fixed I-beam 21.

[0031] When the anti-falling device 3 needs to be replaced to work on other guide rails, the movable I-beam 41 is rotated in the direction of the fixed I-beam 21 where the anti-falling device 3 is located, and the anti-falling device 3 is displaced to the top surface of the movable I-beam 41. Then, the movable I-beam 41 is rotated to align it with the fixed I-beam 21 on one side of the anti-falling device 3. Then, the anti-falling device 3 is dragged so that the U-shaped sliding block 31 slides from the top surface of the movable I-beam 41 to the surface of the fixed I-beam 21.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
