Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to an installation mechanism for a T-shaped bar and a use method thereof. Background Art

[0002] During the shipbuilding process, backward shipbuilding production efficiency and quality levels are issues that need to be urgently addressed in the industry. Compared with other fields, shipbuilding still has many shortcomings in lean production, intelligent manufacturing, digitalization, automation and integration.

[0003] The importance of shipbuilding equipment as a safeguard for improving shipbuilding efficiency and quality reliability is self-evident. A large number of intelligent equipment are urgently needed to replace manual operations and improve the manufacturing level of the shipbuilding industry.

[0004] As a composite profile, T-profiles are widely used in shipbuilding because of the flexible combination of webs and panels. In theory, they can provide any size of section modulus. During shipbuilding, T-profiles must be installed in designated locations according to the requirements of construction drawings. However, T-profiles are generally long in size and inconvenient to carry. It is difficult to install and position T-profiles. There are currently two main installation technologies. One construction technology is to install and position T-profiles completely manually. Usually, it takes about 6 workers to cooperate to achieve installation and positioning. During the installation and positioning process, it mainly relies on manual operation, which is labor-intensive, wastes a lot of manpower, and has low work efficiency. At the same time, since most T-profiles are heavy, there are safety hazards during the positioning and installation process. Another construction technology is to weld a door-type assembly tool on the steel plate, and use the door-type tool to provide external force to press the profile and the steel plate together. This installation method must be welded once each time it is used, and the root left after cutting must be cut and polished. In addition, the assembly work usually requires at least 2 people to cooperate to complete, which is time-consuming and has safety hazards. Summary of the invention

[0005] The object of the present invention is to provide an improved installation mechanism and use method for T-profiles, which can overcome the shortcomings of the prior art of inconvenient installation and positioning and poor precision of T-profiles.
