Description

Technical Field

[0001] This utility model belongs to the technical field of pressure vessel concentricity fine-tuning positioning platform, specifically relating to a hydraulically driven pressure vessel concentricity fine-tuning positioning platform. Background Technology

[0002] A hydraulically driven pressure vessel concentricity fine-tuning positioning platform is a device used to precisely adjust the concentricity of various components of a pressure vessel. It is mainly used in the assembly process of large pressure vessels and typically uses a hydraulic system as its power source. A hydraulic pump forces hydraulic oil into a cylinder, and the linear motion of the piston within the cylinder drives the connected positioning components to move precisely, thereby achieving fine-tuning of the concentricity of the pressure vessel components.

[0003] Specifically, during the assembly process of pressure vessels on the market, especially in the docking stage of key components such as large cylinders, heads, and flanges, strict concentricity adjustment is essential. This step directly affects not only the convenience of subsequent assembly processes but also the uniformity of stress, the stability of medium flow, and the overall safety performance during equipment operation. However, the adjustment methods commonly used in the industry still rely on manual prying with tools such as crowbars and jacks, or rough positioning using simple mechanical supports. These methods depend on the operator's experience, are time-consuming and labor-intensive, and reduce adjustment efficiency. Utility Model Content
