Underwater welding robot for open caisson steel plate

Abstract

The invention belongs to the technical field of open caissons, and particularly relates to an underwater welding robot for an open caisson steel plate. The underwater welding robot comprises an open caisson body and fixing blocks, wherein the plurality of fixing blocks are movably clamped with the upper end surface of the open caisson body, a first mounting cavity is formed in the inner wall of each fixing block, a lifting device is arranged on the inner wall of each first mounting cavity, a moving device is arranged below each lifting device, and a welding device is arranged below each moving device. According to the underwater welding robot for the open caisson steel plate, the welding devices are powered by power connection blocks, a third motor drives a second gear disc to rotate, and then an operation ring is driven to rotate; when the operation ring rotates, due to the fact that a telescopic opening limits the circumferential direction of a welding handle, the welding handle can only stretch out and draw back; and guide columns are guided through arc-shaped guide grooves, so that the welding handle is slowly expanded outwards along with rotation under the rotation of the operation ring, then the welding rod is continuously supplied forwards while the welding rod is used for welding the open caisson body, and then the welding of the open caisson body is completed.

Description

technical field [0001] The invention relates to the technical field of caissons, in particular to an underwater welding robot for caisson steel plates. Background technique [0002] Caisson is a construction technique commonly used in underwater construction. In the construction of bridge foundations, there are mostly square, round, oval and other forms. During construction, the first section is poured in advance, and the bottom is hollowed out after solidification. The concrete block begins to sink, and then the top is continued to be poured, and then hollowed out after completion, and the cycle is repeated. , until it is excavated to the bottom of the foundation, it is composed of walls, partition walls and supports. The caisson foundation is a type of underground structure and deep foundation constructed by the caisson method. It is to make a well-shaped structure (caisson) on the surface first, and then under the enclosure of the well wall, through continuous excavation...

Problems solved by technology

[0004] Based on the existing underwater welding, most of the professional welders put on diving suits and bring oxygen cylinders to dive underwater to weld the inner wall of the caisson. The welding quality of the caisson is a technical problem that affects the welding efficiency of the caisson. The invention proposes a caisson steel plate underwater welding robot
