[0002] With the acceleration of urbanization and the continuous growth of electricity demand, the scale and complexity of overhead power line construction are increasing daily. Many new lines traverse various complex terrains, such as mountainous areas, above rivers, and densely populated residential areas. Furthermore, when upgrading and maintaining existing overhead lines, construction workers face numerous risks, such as close contact with live lines and working at heights. Existing safety protection devices for overhead power line construction mostly rely on a combination of safety ropes and safety belts to protect workers at height. Typically, the safety rope ends with two sub-ropes, each equipped with a buckle. Workers can alternately secure these buckles to the steel bars on the tower, ensuring they remain protected by the safety rope. However, when working on older towers, the steel bars may loosen due to aging during the alternating securing of the sub-ropes, potentially endangering workers. To address the shortcomings of existing technology, this invention provides a safety protection device for overhead power line construction to solve the aforementioned problems.

A reinforcing block 11 is fixedly connected to the other end of the main rope 1. A sub-rope 3 is fixedly connected to one side of the reinforcing block 11.

[0040] When it is necessary to carry out construction on the overhead lines on the old tower, a safety rope 4 needs to be installed. First, pull the handle 52 upward. The handle 52 is fixedly connected to the slide plate 53, which drives the locking block 54 to move upward and compress the first spring 51. After reaching the highest point, the L-shaped connecting plate 42 is fully inserted into the fixing block 111. Then, release the handle 52. The first spring 51 causes the slide plate 53 to return to its original position and drives the locking block 54 to move downward. Thus, the locking block 54 engages with the slot 421 in the L-shaped connecting plate 42. The safety rope 4 is fixedly connected to one side of the L-shaped connecting plate 42, which completes the installation of the safety rope 4.

[0041] Example 2;

The first buckle 22 on the connecting column 2 is fixedly connected to the construction worker's waist belt. After the fall, the second spring 61 inside the shock-absorbing unit 6 is stretched. During the stretching process, the second spring 61 can convert the gravitational potential energy of the fall into elastic potential energy.

The shock-absorbing unit 6 can effectively reduce the impact force during the fall and protect the construction worker.
