Abstract

The invention disclose a welding experiment chamber for simulating a medium-pressure liquid or gas environment, and relates to an underwater welding experiment chamber. The welding experiment chamber aims to solve the problems that for the existing experimental equipment for simulating underwater welding, components in a chamber are not easy to replace, the applicability is poor, the simulated pressure for simulating a welding experiment is low, and only a single pressure medium is available. A chamber bottom is arranged on the upper end face of a platform support; a plurality of chamber penetrating connectors are uniformly arranged in the chamber bottom; a chamber body is arranged above the chamber bottom; two semicircular hoops are buckled to form a ring; two side walls of a trapezoidal groove are tightly matched with an upper inclined plane and a lower inclined plane; an oil cylinder support is fixedly connected with the upper end face of the platform support; two lifting guide rails are symmetrically arranged on the outer side of the oil cylinder support by adopting the vertical center line of the chamber body as a reference; each lifting guide rail is provided with a lifting oil cylinder; four lugs are uniformly distributed on the external wall at the upper end of a barrel; one end of each lifting support is connected with one of the lifting oil cylinders; the other end of each lifting support is connected with two of the four lugs; and a welding platform is arranged on an annular boss. The experiment chamber is used for simulating the underwater welding.

Description

technical field [0001] The invention relates to an underwater welding experiment cabin, in particular to a welding experiment cabin for simulating a medium-pressure liquid or gas environment. Background technique [0002] With the development of marine resources, a large number of steel structures are used in marine engineering, such as submarine oil pipelines, offshore drilling platforms, and sea-crossing bridges. Whether it is the construction of structures or the maintenance of facilities, underwater welding is required. Whether it is the construction of structures or the maintenance of facilities, underwater welding technology has irreplaceable advantages. Underwater wet welding can be applied to pressure environments where the water depth does not exceed 100 meters; when the water depth exceeds 100 meters, underwater high-pressure dry welding is generally used. Regardless of underwater wet welding or high-pressure dry welding, welding is performed in an environment hi...
