[0069] A rotating power member 26, which is fixedly mounted on a side of the second rotating shaft 24 away from the ratchet 21;

[0070] The safety rope 25 is slidably connected to the outer side of the second rotating shaft 24 , and one end of the safety rope 25 is fixedly installed on the outer side of the second rotating shaft 24 .

[0071] The specific implementation method is that the rotating power part 26 includes but is not limited to an asynchronous motor, which is electrically connected to an external power supply and is also controlled by an external PLC programming program. There is a coupling at the output end of the rotating power part 26, which is fixedly connected to the rotating shaft 24 through the coupling. The safety rope 25 is mostly a steel cable safety rope, which is a safety device used to protect workers in high-altitude operations or dangerous environments. It is usually made of high-strength steel wire rope. Its function is to provide reliable support and protection for workers when they are engaged in high-altitude operations to prevent them from falling accidentally.

[0072] The drive assembly 23 comprises:

[0073] A driving ring 233, which is rotatably sleeved on the outer side of the second rotating shaft 24;

[0074] A driving rod 231 rotatably connected to one side of the bottom of the driving ring 233;

[0075] The handle 232 is fixedly mounted on a side of the driving rod 231 away from the driving ring 233 .

[0076] A specific implementation is that the driving rod 231 can be replaced by a telescopic driving rod, which facilitates the staff to adjust the length of the safety rope 25 as the staff descends.

[0077] The limiting assembly 22 includes:

[0078] A limit block 221 slidably connected to the inner wall of the ratchet 21;

[0079] A connecting shaft 222, which penetrates the driving ring 233 and is slidably connected to the inner wall of the driving ring 233;

[0080] A fixing plate 224, which is fixedly mounted on one side of the connecting shaft 222;

[0081] A return spring 223, one end of which is fixedly mounted on a side of the fixing plate 224 close to the driving ring 233, and the other end of which is fixedly connected to a side of the driving ring 233 away from the ratchet 21;

[0082] A translation force member 226, which is fixedly mounted on one side of the driving ring 233 and is located above the return spring 223;

[0083] The baffle plate 225 has a top on one side fixedly connected to the output end of the translation force member 226 , and a bottom on one side fixedly connected to the fixing plate 224 .

[0084] The specific implementation is that the translation force member 226 includes but is not limited to an electric telescopic rod, which is electrically connected to an external power supply and controlled by an external PLC programming program. The end of the connecting shaft 222 away from the baffle 225 is fixedly connected to the limit block 221.

[0085] The device body 1 comprises:

[0086] The extension arm 15 is slidably mounted on the outer side of the second rotating shaft 24;

[0087] A rotating shaft 12, which passes through an end of the extension arm 15 away from the anti-fall assembly 2;

[0088] A fixed column 13 is rotatably sleeved on the outer side of the rotating shaft 12;

[0089] A limit cover 11 is fixedly mounted on the top of the fixing column 13;

[0090] The telescopic assembly 14 is mounted on the inner wall of the fixing column 13 .

[0091] The specific implementation method is that mechanical butter is applied between the rotating shaft 12, the extension arm 15 and the fixed column 13. The mechanical butter is composed of base oil and various additives, has good lubrication and anti-wear properties, can effectively reduce friction and wear between mechanical parts, extend the service life of mechanical equipment, and improve work efficiency.

[0092] The telescopic assembly 14 comprises:

[0093] Two symmetrically arranged fixing blocks 141, which are fixedly mounted on the inner wall of the fixing column 13;

[0094] A fixed shaft 143, which is fixedly installed between two symmetrically arranged fixed blocks 141;

[0095] The rotating arm 142 is rotatably sleeved on the outer side of the fixed shaft 143;

[0096] One end of the connecting rod 144 is slidably connected to the inner wall of the rotating arm 142 , and the other end of the connecting rod 144 is fixedly connected to the bottom of the extension arm 15 .

[0097] The specific implementation is that there is a fixing piece (not shown in the figure) at the opening of the rotating arm 142, which is used to limit the range of movement of the connecting rod 144 to prevent the connecting rod 144 from falling off due to excessive movement.

[0098] Working principle: Before use, the staff first installs the device body 1 in place, then installs the rotating shaft 24 on one end of the extension arm 15, installs the rotating power member 26 on one side of the rotating shaft 24 and installs the safety rope 25 to the outside of the rotating shaft 24, installs the driving assembly 23 on one end of the rotating shaft 24, installs the ratchet 21 on one side of the driving assembly 23, and finally installs the limit assembly 22;

[0099] When in use, the worker ties the non-fixed end of the safety rope 25 to his protective clothing, holds the safety rope 25 with one hand, and holds the handle 232 with the other hand. Each time he descends, he pushes the handle 232, which drives the driving rod 231 to rotate, and the driving rod 231 further drives the driving ring 233 to rotate, and the driving ring 233 drives the connecting shaft 222 to move, and the connecting shaft 222 drives the limit block 221 to slide along the inner wall of the ratchet 21, driving the ratchet 21 to rotate, and the ratchet 21 drives the rotating shaft 24 to rotate. At this time, the safety rope 25 is lowered, and the worker repeats this action until the construction position is reached;

[0100] When the work is finished and the staff needs to return, the translational force member 226 is started, which drives the baffle 225 to translate, and further drives the connecting shaft 222 to translate, so that the limit block 221 is against the inner wall of the ratchet 21. At this time, the rotating power member 26 is started, which drives the rotating shaft 24 to rotate in the opposite direction to pull the safety rope 25 and the staff back.

[0101] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
