Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a conveying roller shaft T-beam welding device. Background Art

[0002] Conveyor rollers are widely used and critical in mining operations. T-beam conveyor rollers are a unique type of conveyor roller that play a crucial role in conveying systems, primarily providing support and positioning. Their unique T-beam design improves the stability and load-bearing capacity of conveyor systems. T-beam conveyor rollers are commonly used for handling heavy materials and transporting them over long distances. Their T-shaped structure provides added support and stability, making them widely used in mining operations. The T-beam design not only increases the roller's load capacity but also helps distribute the stress generated during operation, thereby extending the equipment's service life. Technically, T-beam conveyor rollers consist of several key components. First is the roller itself, typically constructed of high-strength steel or an alloy to withstand heavy loads and prolonged wear. Second is the bearing, which is crucial for ensuring smooth conveyor roller operation. High-performance bearings reduce friction, improve operating efficiency, and reduce energy consumption. Finally, seals prevent dust and impurities from entering the roller body, protecting internal components from damage. These components work together to enable T-beam conveyor rollers to operate stably in a variety of challenging environments.

[0003] Before the T-beam is welded to the surface of the conveyor roller, the web and the outer arc-shaped piece need to be welded and fixed. There is no special welding equipment in the existing technology. It is difficult to accurately align the web using conventional welding equipment, which will cause welding offset, affecting the welding quality and thus affecting the strength of the T-beam. Therefore, we propose a conveyor roller T-beam welding device to solve this problem. Utility Model Content
