Description

Falling proof device

One, technical field

When relating to a kind of transformer station upkeep operation, the utility model guarantees the falling proof device of personal safety.

Two, background technology

Because the wall bushing place does not have the special-purpose firmly hanging point of the safety belt that the operating personnel uses, in the past when the wall bushing place of transformer station upkeep operation, operating personnel's health is in midair, can only armrest grab, pin steps on and holds health, accidentally will fall down, cause personal injury, cause operating personnel's personal safety reliably not guaranteed.This device that transformer station exists is violating the regulations, has not only jeopardized maintainer's personal safety, also seriously causes the insecurity of service work.

Three, summary of the invention

The utility model solves the above-mentioned problems in the prior art exactly, a kind of falling proof device is provided, this device is fixed on the correct position at transformer station wall bushing place, and the hook on the safety belt that the operating personnel uses can firmly be hung thereon, to guarantee operating personnel's personal safety.

For addressing the above problem, technical solution of the present utility model is: a kind of falling proof device, it is by being fixed on the high strength expansion bolt on the body of wall and being fixed on the inner core of expansion bolt or forming with the high strength retainer ring of the inner core one of expansion bolt.

Because the utility model adopted such scheme, the utility model is fixed on the correct position at transformer station wall bushing place, the hook on the safety belt that the operating personnel uses can firmly be hung thereon, to guarantee operating personnel's personal safety.The utility model is simple in structure, the mechanical strength height, and easily the extension of safety belt is gone into and taken, and is safe and convenient to use, installs simple.It is violating the regulations to have eliminated wall bushing place device completely, has improved the security reliability of service work.Be widely used in the upkeep operation at various transformer stations wall bushing place.
