Description

Technical Field

[0001] The utility model relates to the technical field of Bailey plates, and particularly relates to a water jet cutting device for cutting I-beams and U-shaped steel. Background Technique

[0002] The Bailey plate is also known as the Bailey truss, Bailey beam or truss. It was first invented by a British engineer during World War II to meet the need for rapid bridge erection during the war and was named after him. It can be used for highway bridges, assembled gantry cranes, guide beams, bridge erecting machines, hanging baskets, etc. The Bailey plate has the characteristics of simple structure, convenient transportation, rapid erection, large load-bearing capacity, good interchangeability and strong adaptability. When assembling the Bailey plate, the I-beam, U-shaped steel and male and female joints are welded together. Therefore, the male and female joints are one of the important components of the Bailey plate. Most of the existing male and female joints are cut by a sawing machine or a cutting device. During cutting, they are conveyed by rollers. During conveyance, the steel will shift, resulting in low cutting accuracy. A large amount of steel will be wasted during subsequent processing and forming, increasing production costs. In addition, the cut male and female joints need to be manually removed. It is time-consuming and laborious, the production efficiency is not high, and water resources will be wasted. Content of the Utility Model
