Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of steelmaking equipment, and in particular relates to a wear-resistant collector device used in overhead crane power supply systems. Background Technology
[0002] An overhead crane, also known as a bridge crane, is a special type of lifting machinery. Its bridge frame runs on elevated tracks, moving longitudinally along these tracks laid on both sides of the elevated structure. Simultaneously, the lifting trolley moves laterally along tracks laid on the bridge frame, together forming a rectangular working area. Within this area, the overhead crane can lift objects in both longitudinal and lateral directions.
[0003] Overhead cranes, as heavy machinery, play a vital role in industrial production. To ensure their normal operation, the overhead crane's power supply system provides electricity to drive its operation; therefore, the power supply system is crucial to the crane's function. Currently, the overhead crane's power supply system is sometimes connected to a detachable contact line using angle steel sliding contact lines. However, the current connection between the overhead crane's power supply system and the sliding contact line is mostly achieved through current collectors and current collector supports connected to the sliding contact line via detachable contacts. However, most current current current current collectors and current collector supports are strip-shaped, resulting in a small contact area with the sliding contact line. This can easily lead to poor contact between the current collectors / supports and the sliding contact line, causing malfunctions in the overhead crane's power supply system and resulting in significant production losses.
[0004] Furthermore, during prolonged, high-load operation, the current collector, current collector support, and sliding contact line will experience wear and tear, leading to a decline in their performance. This, in turn, can result in poor contact between the current collector, current collector support, and sliding contact line, causing power outages during crane operation and resulting in significant production losses. Additionally, the need for frequent replacement of worn current collectors and current collector supports, which are mostly fixedly installed with the crane's power supply system, further inconveniences production and increases costs for the company.
