To ensure the smooth operation and prolong the service life of the sliding contact line, regular maintenance should be conducted after the line is put into operation.
Brush: It should be inspected every 1-3 months based on the usage of the mobile electrical equipment. Pay special attention to the wear of the brush on the collector. If the wear reaches 5mm, it must be replaced. If loose brushes or uneven wear are found during inspection, the cause should be identified and addressed promptly.
2. Collector: Inspect at least once every quarter. Focus on checking for loose or shifted fasteners, wear on plastic and moving parts, and spring tension (the contact pressure between the collector brush and the rail should be maintained at a consistent level). Address any issues promptly.
Connectors: Inspect at least once per year. Focus on checking for loose bolts, welds, and supports for signs of rust, displacement, etc. Address any issues promptly.
4. Routine Inspections: Focus on checking for significant deviations (greater than 20mm) in the straightness of the track, misalignment, and whether insulating protective components are missing, broken, or damaged. Inspect if the stainless steel channels are lifting. Check for any foreign objects and conductive dust on the track. If necessary, test the insulation resistance to ensure it meets requirements (inter-phase insulation resistance should be 5M).
Special attention must be given to the degree of track overlap, gauge, and tilt deviations, which are considerable. In environments with frequent use, excessive workshop dust, high temperatures, and the presence of water, acids, alkalis, fog, and outdoor use, daily inspections and maintenance must be strengthened.
The power supply safety slider line device consists of two main components, the conduit and the slider line conductor, along with some auxiliary parts, as shown in the figure:
Conducting Cable Duct: A semi-closed, non-standard tube component, which serves as the main part of the safe sliding conducting cable. It can accommodate 2-9 bare conductive tracks as power supply wires, with each track insulated from the others and from the housing, ensuring the safety of power supply and effectively preventing electric shock accidents during maintenance. The ducts produced by Xinxiang Yudong are each 6 meters long and can be connected to any required length. Standard ducts are made in a straight shape, but can also be customized into curved shapes or other special designs as needed.
The sliding contact brush holder is a set of brush shells running within a conduit. The sliding contact is driven by a fork (or a traction chain, etc.) mounted on the electrical equipment (crane, trolley, electric hoist, etc.), ensuring synchronous operation with the equipment. The electrical energy from the sliding contact brush is transmitted through the track to the motor or other control components. The number of poles on the brush holder of the conductor is 3-16, corresponding to the number of tracks within the conduit.
