Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and in particular to a falling prevention device used for GIS equipment maintenance operations. Background Art

[0002] Gas-insulated metal-enclosed switchgear (GIS) has a history spanning decades. Because it encloses key components such as circuit breakers, disconnectors, earthing switches, busbars, transformers, lightning arresters, bushings, cable terminals, and oil and gas casings in a sealed metal container filled with insulating gas, it offers advantages such as small size, minimal footprint, immunity to environmental influences, safe and reliable operation, simple maintenance, and long maintenance cycles. It is now widely used in various substations.

[0003] As a large-scale equipment for power transformation, GIS equipment is large in size and its shell is cylindrical, which is not conducive to maintenance personnel to climb up to carry out the corresponding component maintenance. Take a set of 220kV GIS equipment as an example. The equipment is detailed in the attached Figure 1 .

[0004] According to Section 3.27 of the "Electric Power Safety Work Regulations," any work performed at heights of 2 meters or more above the reference plane, where there is a risk of falling, is considered work at height. Safety harnesses must be used properly when working at height. Safety harnesses should be attached high and used low, and should not be attached to moving, sharp, or unstable objects. Due to these restrictions, maintenance personnel performing maintenance work on GIS equipment lack a safe "high-hang" attachment point, and the issue of preventing falls from heights has become prominent. Summary of the Invention

[0005] The purpose of the present invention is to propose a fall prevention device for GIS equipment maintenance operations, to solve the technical problem of how to provide hanging points for safety belts when GIS equipment is operated at heights, and to prevent workers from falling from heights.

[0009] Preferably, the lifting ring is fixed to the top of the vertical pole, and the bottom of the lifting ring is connected and fixed to the vertical pole.

[0010] Preferably, the lifting ring is fixed to one side of the top of the vertical pole, and the side of the lifting ring is connected and fixed to the vertical pole.

[0011] Preferably, the fixing portion includes an upper clamp, a lower clamp and the locking component; the upper clamp is bent downward, the lower clamp is bent upward, and the upper clamp and the lower clamp are sequentially connected and sleeved on the cylindrical part of the GIS equipment; the top end of the upper clamp is fixedly connected to the bottom end of the vertical pole.

[0012] Preferably, upper fixing plates are respectively provided at both ends of the upper clamp, and a plurality of fixing holes are provided on the upper fixing plates.

[0013] Preferably, the upper fixing plate is inclined upward from the connection between the upper fixing plate and the upper clamp, and the inclination angle is 5 degrees.

[0014] Preferably, lower fixing plates are respectively provided at both ends of the lower clamp, and a plurality of fixing holes corresponding to the upper fixing plates are provided on the lower fixing plates.

[0015] Preferably, the lower fixing plate is inclined downward from the connection between the lower fixing plate and the lower clamp, and the inclination angle is 5 degrees.
