Description

Technical Field

[0001] The invention relates to the technical field of steel structure manufacturing and welding, and in particular to a device and method for laying a rod-shaped ceramic liner for a butt weld. Background Art

[0002] In the on-site welding projects of steel structures in the construction industry, there are often a large number of plate joints that need to be welded. At present, the plate joints of steel structures adopt the single-sided welding and double-sided forming technology with ceramic pads on the back of the weld. Because steel structure projects are mostly distributed in rivers, viaducts and other parts, the back-attached pads of the butt welds generally require the establishment of an aerial working operation platform. Not only is the operation process long, inefficient, costly and risky, it also has adverse effects on personnel safety and the ecological environment.

[0003] Patent document CN217045121U discloses a protective magnetic pad for high-altitude steel structure welding, including a flame retardant layer and a fireproof layer, the fireproof layer is connected to the bottom of the flame retardant layer, the middle of the flame retardant layer is reserved for installing a ceramic pad installation groove for installing a ceramic pad, and the flame retardant layer is also provided with a magnetic suction piece for making the protective magnetic pad as a whole adsorbed under the steel member to be welded. The utility model of the protective magnetic pad for high-altitude steel structure welding has a simple structure and is convenient to be connected under the steel member to be welded when used. When used, the ceramic pad is located under the weld of the steel member to be welded through magnetic connection, and completely covers the weld of the steel member to be welded; so there is no leakage spark, no welding molten iron flows down to the ground, no ceramic pad block falls to the ground, and the installation and removal are flexible, and the magnetic force is safe, reliable and durable. This installation method is too cumbersome and it is impossible to lay the ceramic pad continuously.

[0004] Patent document CN215393365U discloses a reinforcement device for a ceramic pad for a single-sided welding and double-sided forming weld, including a steel plate strip and a plurality of magnets; the steel plate strip has a groove, the steel plate strip is arranged below the ceramic pad and the steel plate parent material, and the ceramic pad is located in the groove, and the bottom and side walls of the groove abut against the ceramic pad to keep the ceramic pad from displacement; the plurality of magnets are arranged on both sides of the steel plate strip, and the ends of the steel plate strip are connected and fixed to the lower end surface of the steel plate parent material through the plurality of magnets. The reinforcement device improves the forming quality of the back side of the weld and improves the fatigue resistance of the weld; at the same time, it greatly reduces the post-weld finishing and grinding work, reduces labor intensity, is beneficial to the health of construction workers, and reduces environmental pollution. Similarly, the installation method is too cumbersome and it is impossible to lay the ceramic pad continuously.

[0005] Patent document CN108176910A discloses fixing ceramic liners by aluminum parts, but the installation method is too complicated and costly, and the ceramic liners cannot be laid continuously.

[0006] Therefore, developing a ceramic lining laying device and process with short operation process, high efficiency, low cost and personnel safety is the current focus. Summary of the invention
