Quick-dismantling corrugated pipe replacing device

Technical Field

The utility model relates to the field of connecting pipelines, in particular to a quick-dismantling type corrugated pipe replacing device.

Background

In electrical primary high voltage equipment, bellows devices are widely used. The corrugated pipe is made of rubber, has certain elasticity, is shaped like a wave, and is fixed in a manner that two ends are fixed by anchor clamps. Due to its soft rubber composition, it is prone to age and lose elasticity, and even to become brittle and crack. In a horizontal structure, the shape becomes softer after being heated, and collapse can be formed; secondly, because the only fixing mode is the anchor ear, after the anchor ear loosens, can cause the bellows to collapse and lead to its and electrified body interval to shrink or contact electrified body, make equipment have very big ground connection risk. In the vertical structure, the fixing of the device completely depends on the anchor ear, and the risk of loosening, falling and leading to grounding of high-voltage equipment is also caused. The accident of grounding high-voltage equipment occurs due to the aging and loosening of soft rubber. In some cases of dismantling the corrugated pipe, the corrugated pipe is easy to damage and inconvenient to carry out work because the corrugated pipe needs to be internally coiled and fixed by using a C-shaped clamp; secondly, during the removal and recovery of the bellows, a variety of tools are required to be knocked into place, which is laborious and prone to staple damage.
