[0025] The first embodiment of this utility model is as follows:

[0026] A safety protection device for preventing iron tower falls includes a main body, which includes a first upright plate 7 and a second upright plate 6 connected to each other. The main body also includes two first pins 8. The first upright plate 7 and the second upright plate 6 are connected by the first pins 8. The first upright plate 7 and the second upright plate 6 have the same structure and are snapped together after being flipped over. The two are connected together by the two first pins 8.

[0027] A clamp assembly is provided on one side of the main body. The clamp assembly includes a first clamp and a second clamp 2. The first clamp is located at the lower part of the first upright plate 7, and the second clamp 2 is located at the upper part of the second upright plate 6. At the same time, there is a certain gap between the first clamp and the second upright plate 6. The gap is larger than the diameter of the steel cable 1. Both the first clamp and the second clamp 2 are annular structures with an inner opening. There is a notch between the first clamp and the second clamp 2. When using, first lift the main body horizontally so that it is perpendicular to the steel cable 1. Then, put the steel cable 1 into the notch. Then rotate the main body 90 degrees so that the steel cable 1 enters the gap. Then move the main body laterally so that the steel cable 1 is inserted into the first clamp and the second clamp 2 to complete the installation.

[0028] On the other side of the main body, a braking assembly adapted to the clamp assembly is provided. The braking assembly includes a first braking arm and a second braking arm that are rotatably connected to the main body via a first pin 8. A first braking head 3 is provided at the end of the first braking arm facing the first clamp, and a second braking head 15 is provided at the end of the second braking arm facing the second clamp 2. A second pin 10 is provided at the ends of the first and second braking arms. The horizontal height of the first pin 8 on the first braking arm is higher than the height of the first limiting head 4, and the horizontal height of the second pin 10 on the second braking arm is higher than the height of the second limiting head 4. The first and second braking arms are connected by a connecting plate 12 via the second pin 10 and form a linkage structure. The line connecting the two first pins 8 and the two second pins 10 forms a parallelogram structure. When the connecting plate 12 is moved upward, the linkage structure generates a linkage effect, causing the first braking head 3 and the second braking head 15 to rotate downward, so that the first braking head 3 and the second braking head 15 can enter the interior of the main body. At this time, the steel cable 1 can be inserted into the gap.

[0029] A limiting component is provided at the notch. A limiting box is provided between the first upright plate 7 and the second upright plate 6. The limiting box contains a spring 9 and a limiting arm. The two ends of the limiting arm extend out of the limiting box and are respectively connected to the limiting head 4 and the limiting ring 11. The end of the limiting box facing the limiting head 4 is provided with a notch 5 that matches the limiting head 4. In use, when the steel cable 1 is first inserted into the notch, it will push against the limiting head 4 to make it move. When the steel cable 1 is inserted into the first clamp and the second clamp 2, the limiting head 4 will also move towards the steel cable 1 under the action of the spring 9. After the steel cable 1 is inserted into the first clamp and the second clamp 2, there is a small distance between the steel cable 1 and the limiting head 4. On the one hand, it can restrict the steel cable 1 from detaching from the first clamp and the second clamp 2. On the other hand, it will not affect the sliding of the steel cable 1 in the first clamp and the second clamp 2.

[0030] The end of the first braking arm is provided with a connecting arm 13, and a connecting ring 14 is provided on the connecting arm 13. When in use, the safety rope can be fastened to the connecting ring 14.

[0031] In the event of an emergency, the safety rope causes the connecting ring 14 to move downwards, creating a linkage that tightly engages both the first brake head 3 and the second brake head 15 with the steel cable 1, thereby generating braking force to prevent the person from falling further.

[0032] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
