[0002] A pressure vessel is a special container that can withstand high pressure inside. It plays a vital role in many industrial fields, such as petrochemicals, energy production, and pharmaceuticals. The design, manufacture, use, inspection, and maintenance of pressure vessels must follow strict national standards and industry regulations to ensure their safety and reliability.

[0003] During the installation process of some existing pressure vessels, they need to be hoisted to the predetermined location before being lowered for installation. During the process of lowering the pressure vessel, its foot pad will first touch the ground. Due to the lack of a buffer structure, when the weight of the container is large, the foot pad is very likely to be deformed due to the strong impact force, resulting in deviations between the foot pad and the embedded screw during installation, which has a high negative impact on the safety during subsequent use. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a pressure vessel with a buffer device to solve the problem that some of the existing pressure vessels proposed in the above background technology need to be hoisted to a predetermined location before being lowered for installation during the installation process. During the process of lowering the pressure vessel, its foot pad part will first contact the ground. Due to the lack of a buffer structure, when the weight of the container is large, the foot pad is very likely to be deformed due to a strong impact force, resulting in a deviation between the foot pad and the embedded screw during installation, which has a relatively high negative impact on the safety during later use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure vessel with a buffer device, comprising a pressure tank, a tripod fixedly connected to the bottom of the pressure tank, a plurality of tripods symmetrically arranged, foot pads fixedly connected to the bottom of the tripods, a plurality of screw holes symmetrically arranged on the inner sides of the foot pads, a screw rod fixedly connected to the top of the foot pads, a plurality of screw rods symmetrically arranged, a plug fixedly connected to the top of the screw, a spring movably connected to the outer side of the screw rod, a lifting plate slidably connected to the outer side of the bottom end of the plug, a bottom of the lifting plate fixedly connected to a bottom frame, and a buffer pad fixedly connected to the bottom of the bottom frame.

[0006] Preferably, adjacent tripods are fixedly connected with cross bars, a plurality of cross bars are symmetrically arranged, and the tops of the tripods are fixedly connected with pressure tanks.

[0011] Preferably, a ruler is fixedly connected to one side of the tripod, and a pressure tank is fixedly connected to the top of the tripod.
