Rapid replacement device for RG-RH vacuum degassing furnace tank car drag chain

Abstract

The invention discloses a rapid replacement device for RG-RH vacuum degassing furnace tank car drag chain. The rapid replacement device comprises a bottom plate, supporting plates are arranged on thetwo sides of the upper end of the bottom plate, a two-layer plate is arranged at the upper ends of the two supporting plates, lifting devices are arranged on the periphery of the upper end of the two-layer plate, jacking frame beams are arranged at the upper ends of the lifting devices, and frame side beams are arranged on the two sides of the upper ends of the jacking frame beams. A supporting beam is arranged in the middle of the upper side of the bottom plate, a bottom cross beam is arranged at the upper end of the supporting beam and penetrates through the upper end of the two-layer plateto be provided with a base, a jack is arranged at the upper end of the base, and a top cross beam is arranged at the upper end of the jack. Jacking frame lower cross beams are arranged on the lower sides of the jacking frame beams, a plurality of jacking frame beams are arranged on the upper sides of the jacking frame beams, and drag chain baffles are arranged at the two ends of the upper sides ofthe jacking frame beams. The jack is used for jacking the jacking frame beams, so that the weight of various pipelines in the drag chain is pressed on the jacking frame beams, and the drag chain canbe freely disassembled, overhauled and replaced.

Description

technical field [0001] The invention relates to a quick replacement device for drag chains of RG-RH vacuum degassing furnace tankers. Background technique [0002] In the replacement and maintenance work of the drag chain of the RH vacuum degassing furnace, we often encounter that the drag chain is damaged by individual joints, causing the entire drag chain to twist, break, deform, tilt or even fall to the ground, which will seriously cause pipelines and Line damage, scratches, breakage, etc., seriously affect the normal production and operation of the degassing furnace, and must be replaced and repaired. However, due to the long drag chains of these devices, there are many tow cable lines, various hydraulic and gas pipelines inside the drag chains, and the weight of the pipelines is large, and they are easily entangled when they are scattered, so it is difficult to replace them. One is that after the tow chain is dismantled, the cable lines, hydraulic and gas pipelines tow...

Problems solved by technology

[0002] In the replacement and maintenance work of the drag chain of the RH vacuum degassing furnace, we often encounter that the drag chain is damaged by individual joints, causing the entire drag chain to twist, break, deform, tilt or even fall to the ground, which will seriously cause pipelines and Line damage, scratches, breakage, etc., seriously affect the normal production and operation of the degassing furnace, and must be replaced and repaired

However, due to the long tow chain of these equipment, there are many tow cable lines, various hydraulic and gas pipelines inside the tow chain, and the weight of the pipeline is large, and it is easy to get entangled when scattered, so it is difficult to replace

One is that after the tow chain is dismantled, the cable lines, hydraulic and gas pipelines towed by it will fall freely and scatter, and it is not easy to collect according to the original position; Some work areas are relatively narrow, and it is not easy to change operations due to the large number of people. Third, manual handling and moving pipelines are prone to misalignment and winding. Can cause downtime and affect production
