Description

Technical Field

[0001] This utility model belongs to the field of infrastructure safety protection devices, and specifically relates to an independent fall protection device for personnel installed on a track. Background Technology

[0002] In rail-related work scenarios, whether it's track construction or routine maintenance and repair of track equipment, workers face the risk of falling from heights. A fall accident often poses a serious threat to the lives of workers, and can also cause significant economic losses to companies and negative social impacts.

[0003] Currently, common fall protection measures for rail operations mainly rely on traditional safety equipment, such as simple combinations of safety belts and ropes. While these devices offer some protection, they have several limitations. Firstly, traditional safety belts and ropes cannot move flexibly with the workers during equipment movement, easily becoming entangled or jammed, restricting workers' freedom of movement and reducing work efficiency. Secondly, single protective measures lack redundancy; if a critical component malfunctions, such as a broken safety rope or a loose safety belt buckle, it cannot provide effective protection for the workers, making it difficult to guarantee their safety throughout the entire operation.

[0004] Furthermore, existing fall protection devices are often integrated with the work equipment, lacking independence. When the equipment malfunctions and requires emergency evacuation or special operations, these fall protection devices cannot function independently, failing to meet the workers' need for independent safety protection. Therefore, it is urgent to develop an independent fall protection device that can move flexibly with the equipment, possesses independent safety protection functions, has a stable structure, and is easy to operate.
