After the overhaul of the maintainer is finished, the safety rope is gradually stretched in the process of moving downwards along with the climbing frame, and when the safety rope moves downwards to the bottom of the tower body, the safety rope is separated from the safety belt, and the safety rope is fixed on the tower body through the fixing device so as to be used next time. Compared with the prior art, the invention not only can control the falling speed of the maintainer due to accidents, but also can play a role of protection at any time in the climbing process of the maintainer. And the differential self-locking device and the safety rope are always fixed on the iron tower, so that the iron tower is very convenient to overhaul quickly, and the overhaul efficiency is improved.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, the anti-falling device for a high-voltage transmission line iron tower in the present embodiment includes an iron tower, a climbing frame 2, a differential self-locking device 3, a safety rope 4, and a fixing device 5.

The iron tower comprises a tower body 1, wherein the tower body 1 is almost vertical, and mainly plays a role in supporting a wire cross arm of the iron tower. Through a lot of work, it is found that the worker mainly drops from the tower body 1 during the climbing process, and therefore it is necessary to ensure the safety of the worker during the climbing process of the tower body 1.

The climbing frame 2 is used as a main tool for a maintainer to climb the iron tower. Climbing frame 2 is fixed the setting on the body of the tower 1 of iron tower from lower to upper, and the workman climbs the iron tower upper end from climbing frame 2 during the maintenance, then overhauls the iron tower. The climbing frame 2 is a universal tool on the iron tower and will not be described in detail here.

The differential self-locking device 3 comprises a fixed end and a using end, wherein the fixed end is fixed at the top end of the climbing frame 2 or the top end of the tower body 1. The main function of the differential self-locker 3 is to limit the falling speed of the safety rope 4 when the safety rope 4 falls. The differential self-locker 3 is a common tool and will not be described in detail herein. Specifically, the fixed end of the differential self-locking device 3 is a hook 6, a hanging hole 7 is correspondingly arranged at the top end of the climbing frame 2 or the tower body 1, and the hook 6 is hung in the hanging hole 7 to realize the connection and fixation of the two.

Safety rope 4, safety rope 4 one end is connected with the user end of differential auto-lock ware 3, and safety rope 4's the other end passes through fixing device 5 can dismantle the connection in the lower part of body of the tower 1. The end of the safety line 4 near the fixing means 5 is provided with a suspension loop 41.

Normally, the safety line 4 is fixed to the lower part of the tower 1 by a fixing device 5. When the iron tower needs to be overhauled, an overhaul personnel firstly stands at the bottom of the iron tower, wears a safety belt, detaches the fixing device 5, takes down the safety rope 4 and is connected with the safety belt (the hook 6 of the safety belt is connected and fixed with the hanging ring 41 on the safety rope 4), then the overhaul personnel climb onto the iron tower along with the climbing frame 2, in the ascending climbing process, the safety rope 4 is gradually taken back into the differential self-locking device 3, when the overhaul personnel accidentally fall, the safety rope 4 is driven to fall down, when the differential self-locking device 3 detects that the falling speed of the safety rope 4 exceeds a set value, the safety rope 4 is locked to be prevented from falling, the overhaul personnel cannot fall too fast, and the safety of the overhaul personnel is ensured.

After the overhaul of the maintainer is finished, the maintainer gradually stretches the safety rope 4 in the process of moving down along with the climbing frame 2, and when moving down to the bottom of the tower body 1, the safety rope 4 is separated from the safety belt, and the safety rope 4 is fixed on the tower body 1 through the fixing device 5 so as to be used next time.

And the fixing device 5 is mainly used for fixing the safety rope 4. Including apron 51 and lid 52, lid 52 fixed connection is on body of tower 1, is equipped with the via hole 53 that is suitable for holding safety rope 4 on apron 51, and the diameter of link 41 is greater than the diameter of via hole 53 on the safety rope 4 to guarantee that safety rope 4 can not break away from fixing device 5 after fixing in via hole 53. The cover plate 51 is fixed to the cover 52 by bolts 54. Specifically, the number of the bolts 54 is two, and screw holes are provided on the cover plate 51 and the cover 52 on both sides of the through hole 53, and the bolts 54 are screwed into the screw holes to fix the cover plate 51 to the cover 52.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
