Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to a novel ear-type support structure. Background Art

[0002] For pressure vessels with high design temperatures and supported by ear-type supports, radial displacement of the equipment is considered. That is, oblong holes are opened radially on the bottom plate of the ear to meet the expansion requirements of the equipment. At the same time, it is generally adopted to add springs or set low-friction pairs at the bottom of the ear to meet the pipeline force requirements. The addition of springs mainly solves the axial stress in the pipeline. In this case, the ear does not serve as a load-bearing support. If this method is used, the radial expansion of the equipment will be restricted. Therefore, considering the actual engineering, this method is not recommended for occasions where the equipment is subject to radial expansion.

[0003] The method of setting up a low-friction pair is to use the ear seat as a load-bearing bracket, and the low-friction pair can meet the expansion requirements of the pipeline. Therefore, from the perspective of engineering practice, this method is recommended for occasions where the equipment has radial expansion and the pipeline force needs to be considered at the same time. However, the ear seat structure using a low-friction pair requires an oblong hole to be opened on each ear seat base plate in the direction of the pipeline force. The direction of the oblong hole is inconsistent with the direction of the radial oblong hole of the equipment, that is, the installation position of the anchor bolts of the two oblong holes is the same, but the directions of the oblong holes are different. For the ear seat base plate, if oblong holes are opened in two directions, the nuts cannot be tightened. Therefore, it is necessary to design a new ear support structure. Utility Model Content

[0004] The purpose of the utility model is to provide a novel ear-type support structure to solve the problem that the existing ear-type support structure using a low-friction pair requires an oblong hole to be opened on each ear-type base plate in the direction of the pipeline force, and the direction of the oblong hole is inconsistent with the direction of the radial oblong hole of the equipment, that is, the installation position of the anchor bolts of the two oblong holes is the same, but the directions of the oblong holes are different. If the oblong holes are opened in two directions on the ear-type base plate, the nut cannot be tightened.
