Description

Technical Field

[0001] This utility model relates to a bearing housing protection structure for a feeding roller conveyor of a T-section assembly machine for ore carriers, belonging to the technical field of feeding roller conveyors. Background Technology

[0002] Driven by the growing global demand for bauxite transportation and the trend towards green shipping, very large bauxite ore carriers (VLCCs) face new requirements in terms of cargo efficiency, energy consumption, and environmental protection. The T-sections used in ore carriers are made of high-strength marine steel (such as AH36 / DH36), with a common web height range of 200-800mm and a thickness of 15-40mm, to meet the load-bearing requirements of the cargo hold structure. In some special areas (such as hatch coamings), asymmetrical T-sections (e.g., thickening one side of the web) may be used to optimize stress distribution. During the assembly of the T-sections by the assembly machine, a feeding roller conveyor is required to transport the T-sections. The feeding roller conveyor consists of multiple parallel rollers, mostly made of carbon steel (chrome-plated) or stainless steel. In some precision applications, polyurethane-coated rollers are used to reduce material wear. Drive methods include motor-chain drive (for heavy loads) or electric roller direct drive (for light loads and high-speed applications).

[0003] Currently, the bearing housings of the feeding roller conveyor of the T-profile assembly machine are exposed. During production, assembly, and hoisting, the bearing housings are frequently bumped, causing damage and affecting the service life of the feeding roller conveyor. Workpieces being moved around the feeding roller conveyor may also collide with the bearing housings, making it difficult to provide cushioning and effective protection. Furthermore, it is not easy to protect the structure from rapid installation. Utility Model Content

[0004] This utility model provides a bearing housing protection structure for the feeding roller conveyor of an ore carrier T-section assembly machine to solve the technical problem of easy damage to the roller conveyor.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides a bearing housing protection structure for the feeding roller conveyor of an ore carrier T-section assembly machine, comprising: The feeding roller conveyor consists of a base and an outer ring of a roller shaft.

The support plate 6 is located on both sides of the ball bearing and is connected by the connecting plate 7. The top of the support plate 6 is provided with a cover plate 8. The side wall of the support plate 6 is welded with a buffer plate 10. The buffer plate 10 is fixedly connected to the top surface of the base 1 through the angle plate 11. The top surface of the cover plate 8 is provided with a top plate 14, and the top plate 14 is fixedly connected to a guide plate 12 located above the roller shaft 5.

[0026] There are two bases 1, and each base 1 is fixedly installed with multiple evenly distributed ball bearings. Each ball bearing consists of a bearing housing 2, an outer bearing ring 3, and an inner bearing ring 4. The bearing housing 2 is fixedly installed on the top surface of the base 1, and the outer bearing ring 3 is fixedly installed on the top of the bearing housing 2. The inner bearing ring 4 is rotatably connected inside the outer bearing ring 3, and the inner bearing ring 4 is fixedly connected to both ends of the roller shaft 5.

[0027] In this technical solution, the ball bearing is installed on the base 1, the bearing housing 2 is installed on the base 1, and the roller shaft 5 is effectively rotated by the relative rotation of the outer ring 3 and the inner ring 4 of the bearing, thereby improving the efficiency of T-shaped material conveying.

[0028] There are two support plates 6, both of which are welded and fixed to the base 1. Both support plates 6 are L-shaped and are respectively arranged on both sides of the ball bearing. Both ends of the connecting plate 7 are fixedly connected to the support plates 6 by screws. The connecting plate 7 is arranged below the roller shaft 5.
