The power line part (Trial) of the "Electricity Safety Work Regulations" issued by the State Grid Corporation stipulates: "Double safety belts with backup ropes should be used when working at high altitudes on towers. The safety belts and safety ropes should be hung on different parts of the tower. On the components, the safety belt should be prevented from falling out of the top of the pole or damaged by sharp objects. When personnel are shifting, the hand-held components must be firm and must not lose the protection of the backup rope. 220kV and above line towers should be equipped with high-altitude workers Anti-fall safety protection devices for upper and lower towers." The regulations also stipulate: "Any work carried out at a location 2m or above from the ground (the reference plane of the falling height) shall be regarded as a high-altitude operation."

High-altitude operations on transmission lines mainly refer to human body displacement, upward or downward activities on transmission line iron towers and cement poles. For the iron tower, the displacement is generally carried out by setting the foot nails or climbing ladders on the steel pipe of the iron tower. During the movement, the safety belt cannot achieve real-time and full-range protection. Therefore, the operator must be mentally high when performing high-altitude mobile operations on the iron tower Concentration, down-to-earth, steady hands, coordination of climbing movements and prevention of possible sudden hidden dangers.

A fall prevention device for a transmission line iron tower or a concrete pole, comprising:

A fall-prevention outer frame 1 that can be matched with the hanging ring of the safety belt is connected with the transmission line iron tower or the cement pole, and the adjacent fall-proof outer frames 1 are connected end to end in sequence and arranged along the extension direction of the transmission line iron tower or the cement pole;

One end is rotatably connected with the transmission line iron tower or cement pole, and the other end is built on the movable piece 2 on the anti-fall outer frame 1.

With the device provided by this program, the operator preferably uses a double-safety safety belt. Put a hanging ring of the safety belt on the anti-fall frame 1, and the staff will drive the hanging ring to move during the climbing process. Since the movable piece 2 and the anti-fall frame 1 are erected, the climbing of the operator will not be affected; If the staff accidentally falls, the movable piece 2 closest to the hanging ring will block the movement of the hanging ring, thereby preventing the operator from continuing to descend and effectively protecting the staff.

Adjacent fall-preventing outer frames 1 are connected end to end and arranged along the extension direction of the transmission line iron tower or cement pole. Hanging ring is hung on the next anti-falling outer frame 1, and then the hanging ring on last anti-falling outer frame 1 is taken off to continue climbing. During the climbing process, the hanging loop of the safety belt is always connected with the anti-falling outer frame 1, so as to provide full-time and real-time protection for the operators.

The structure of the anti-falling frame 1 can be various, one of which is an embodiment: the anti-falling frame 1 includes:

Two iron frames arranged in parallel and a cross bar arranged in the middle of the iron frames for erecting the movable piece 2 . The anti-fall outer frame 1 is in the shape of a ladder as a whole. Two iron frames arranged in parallel are connected with transmission line iron towers or cement poles. A cross bar is arranged in the middle of the iron frames arranged in parallel. The frame 1 plays the role of structural reinforcement, and on the other hand, it can play the role of limiting the movable piece 2 .

The second embodiment is: the anti-fall outer frame 1 is a steel frame, and the steel frame is provided with a limit protrusion corresponding to the position of the movable piece 2, and the limit protrusion further prevents the downward movement of the movable piece 2. The steel bar has a certain strength, which can ensure the use strength of the anti-fall outer frame 1, and the area of the limiting protrusion of the steel bar 2 is preferably equal to or greater than the area of the movable piece 2, so as to ensure that the hanging ring can be effectively blocked from falling during use. Ensure the safety of workers.

In order to further optimize the above technical solution, in a specific embodiment of the present invention, the anti-fall outer frame 1 is a trapezoidal anti-fall outer frame. There is no mutual influence during the installation process of the frame 1, which can facilitate the installation of the anti-fall outer frame 1, and the adjacent anti-fall outer frames 1 can be closely connected to provide good real-time and full-range protection.

In order to ensure that the movable piece 2 can be rotatably connected with the transmission line iron tower or the cement pole, the movable piece 2 is connected with the transmission line iron tower or the cement pole through a rotating shaft, and the movable piece 2 rotates around the rotating shaft 2, or the movable piece 2 is connected with the transmission line iron tower or the cement pole hinged. This solution may also adopt other connection methods that can realize this solution, which are not specifically limited here.

In order to ensure the connection strength of the anti-fall outer frame 1, the anti-fall outer frame 1 is welded or bolted to the transmission line iron tower or cement pole.

In order to avoid setting too many movable pieces 2, which will cause the transmission line tower or cement pole to be loaded, the distance between the movable pieces 2 is 0.4m to 0.6m, and the distance between the movable pieces 2 is preferably close to the distance between the foot nails .

In order to further optimize the above technical solution, in a specific embodiment of the present invention, the length of the anti-fall outer frame 1 is 4m to 6m. If the length of the anti-fall outer frame 1 is too long, it will affect its use strength and is inconvenient to install. Preferably, the length of the anti-fall outer frame 1 is set to 4m-6m, and four or five movable pieces 2 are arranged on the anti-fall outer frame 1 .

When the staff descends from the tower, the two hanging loops on the safety belt are used alternately. The specific operation steps are: one of the hanging loops is matched with a movable piece close to the staff, and the other hanging loop is matched with the movable piece close to the staff. The next movable piece of the tower cooperates, and the next movable piece is located under the movable piece close to the staff. After the staff moves down, repeat the above actions to ensure that the staff can also achieve no blank protection in the process of descending the tower.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
