Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a pressure tank head cover disassembly and assembly device. Background Art

[0002] At present, with the development of modern science and technology, unmanned, large-scale, intelligent underwater products have become one of the technologies that technology research and development units are competing to innovate. Underwater pressure-bearing sealed pressure tanks are one of the indispensable parts. They are usually used to load various functional components and for experimental assembly to simulate the high water pressure environment of the ocean. Before the pressure tank is actually used, it must undergo several sealing performance tests in the production process. Only after it operates normally in an artificially created high-pressure environment can it proceed to the next step of real environment application.

[0003] The existing pressure tank structure generally adopts a cylindrical structure, an O-ring, and a threaded locking head cover. The specific operation of its normal disassembly and assembly is: the head cover of the pressure tank is hung with a crane, and the connecting screws of the head cover and the pressure tank are unscrewed using a special tool. During this process, it is necessary to manually apply force to the head cover in the axial direction to prevent it from falling off from the front end face of the pressure tank and causing damage to the operator or surrounding objects. Then the head cover is lifted by controlling the crane. This is the disassembly process. When the head cover is installed, the order is reversed. First, the head cover is lifted and placed on the front end face of the pressure tank and aligned with the pressure tank. Then the head cover is manually pushed into the pressure tank and the head cover is fastened to the pressure tank with connecting screws. When the pressure tank is new, it is particularly difficult to use during the running-in period. It is particularly difficult to disassemble and assemble. Sometimes the axis cannot be aligned and stuck. When the pressure tank has been used for a long time, due to damage, wear and insufficient lubrication, the pressure tank head cover will also be stuck or laborious. At the same time, the safety and reliability of the disassembly and assembly process cannot be guaranteed.

[0004] With regard to the problem of the head cover of the pressure tank getting stuck during the disassembly and assembly process in the prior art, no effective solution has been proposed yet. Utility Model Content
