Description

Technical Field

[0001] The present invention belongs to the technical field of protective devices, and particularly relates to a protective device for roof operation. Background Art

[0002] During the production, maintenance and operation of rail transit vehicles, there are often situations where operators need to climb onto the roof for installation, inspection or debugging work. To ensure operation safety, anti-falling measures such as climbing handrails and protective ropes are usually set on the platforms on both sides of the roof. However, the coverage ability of traditional fixed protective structures in the end regions of the vehicle roof is limited. Especially when the vehicle lengths are different or the platform spacings vary greatly, the existing protective devices are difficult to be compatible with different vehicle models, which easily leads to protective blind spots and poses relatively high safety hazards.

[0003] Therefore, designing a protective device for roof operation with a simple structure, convenient operation and effective protection for roof operators has become an urgent technical problem for those skilled in the art.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention
