Problems solved by technology

The flange cover of the pipeline is heavier as the diameter of the pipeline increases, usually more than 400 kg. The maintenance personnel need hoisting equipment to disassemble and install, which is very inconvenient for maintenance. At the same time, there is unsafety. Space also needs the protection of security strength

Embodiment 1

[0028] Example 1, such as Figure 1-2 As shown, a rotary pipeline device according to an embodiment of the present invention includes: a rotary flange cover 4, a shaft seat 2, a sleeve 3 and a suspension mechanism, wherein the suspension mechanism includes a lifting lug 6, a hook 5 and an arc Shaped boom 1.

[0029] The rotary flange cover 4 is installed at the pipe mouth of the pipeline 8. The rotary flange cover 4 is composed of a rotary cover 4-1 and a flange 4-2. The flange 4-2 is installed at the pipe mouth. The middle part of the rotary cover 4-1 is installed The handle 7, the rotary cover 4-1 and the flange 4-2 are fixedly connected by bolts, one side of the rotary cover 4-1 and one side of the flange 4-2 are rotatably connected by a connecting piece, and one side of the rotary cover 4-1 is provided. Arc mouth, rotary cover 4-1 can rotate horizontally.

[0030] The shaft seat 2 is welded and fixed on one side of the flange 4-2, and the two shaft seats 2 are installed ...

Abstract

The invention discloses a rotary pipeline device. The rotary pipeline device comprises a rotary flange cover, shaft bases, a sleeve, a lifting lug, a lifting hook and an arc lifting arm, wherein the rotary flange cover is formed by a rotary cover and a flange, the flange is mounted on an opening of a pipeline, a handle is mounted in the middle of the rotary cover, the rotary cover is connected with the flange through a bolt, one side of the rotary cover is rotatably connected with one side of the flange, an arc opening is formed in one side of the rotary cover, and the rotary cover can rotate horizontally; the shaft bases are welded to one side of the flange, and the two shaft bases are symmetrically mounted based on the center axis of the flange; the sleeve is welded to one side of the flange and perpendicularly mounted between the two shaft bases; the lifting lug is welded to the top of the rotary cover, and a first round hole is formed in the middle of the lifting lug; the lifting hook is mounted above the lifting lug and formed by a perpendicular section and a lifting ring section integrated with the perpendicular section, and the lifting ring section penetrates through the first round hole; one end of the arc lifting arm penetrates through the sleeve and is rotatably mounted in the sleeve, and the other end of the arc lifting arm is rotatably mounted at the end of the perpendicular section. The rotary pipeline device has the advantages of solving the problem of hoisting during overhaul and the problem that no temporary storage space is needed for the disassembled flange cover.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a rotary pipeline device. Background technique [0002] Due to the corrosiveness and abrasiveness of the working medium or the working environment of the pipeline, anti-corrosion and anti-wear measures are generally required on the side of the pipeline that acts on the corrosive and abrasive environment, such as the inside and outside of the pipeline. The usual anti-corrosion and anti-wear measures are anti-corrosion and anti-wear layers such as lining rubber or glass flakes. For large-diameter pipes, such as slurry spray pipes installed in desulfurization absorption towers, the inside and outside of the pipes are lined with rubber or glass flakes. Due to the erosion of limestone slurry, its rubber layer or glass flake layer is damaged to varying degrees, and often needs to be overhauled. The flange cover of the pipeline is heavier as the diameter of the pipeline increases, u...
