Description

Technical Field

[0001] The utility model relates to the technical field of transportation support for SCR assembly pipes, and particularly relates to a transportation support structure suitable for SCR assembly pipes. Background Art

[0002] As an exhaust gas treatment system for ships, the SCR system plays an important role in ships. The stainless steel reductant mixing pipe and mixer of the SCR, as part of the urea injection system in the SCR system, need to be coated with a heat insulation layer on the outer surface of the pipe body except for the area within 150 mm from both end faces of the flange. A layer of iron sheet is wrapped around the pipe body to isolate the heat dissipation inside the assembly pipe, which directly affects the smooth progress of the sea trial work of the shipyard.

[0003] Currently, for the SCR reductant mixing pipe and mixer widely used on ships, the end flanges of the two are connected by fasteners, and a bracket is provided at one end of the SCR reductant mixing pipe to connect with the ship's cabin. The outer surface of the SCR reductant mixing pipe and mixer is coated with a relatively soft heat insulation layer. Since there is a bracket at the tail end of the SCR reductant mixing pipe and no support is provided at its front end, after the assembly of the reductant mixing pipe and mixer is completed, the front end is padded with hard materials such as wooden blocks to make its front end and rear end at the same horizontal plane. During the transportation and driving process of the vehicle, the outer surface of the heat insulation layer is collided, resulting in deformation. Finally, when the shipyard receives the SCR assembly pipe product, it is often found that the insulation coating on its outer surface is damaged and deformed. Moreover, the existing support method not only makes it difficult to ensure that the outer surface insulation coating of the assembly pipe is not damaged, but also reduces the stability and safety of the assembly pipe during transportation. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the purpose of the utility model is to provide a transportation support structure suitable for SCR assembly pipes. The overall design of the transportation support structure is reasonable, the structure is simple, and the operation is convenient. It can effectively support the front end of the SCR reductant mixing pipe and the tail end of the mixer, and can make its height at the same horizontal plane as the tail end of the SCR reductant mixing pipe. During the transportation and driving process of the vehicle, the outer surface of the coated heat insulation layer is not easily collided and deformed, effectively ensuring that the insulation coating is not damaged, and effectively improving the stability and safety of the assembly pipe during transportation.
