Daily maintenance knowledge of the sliding line

The trolley wire consists of a guide rail, a sheath, a current collector, a hanger, a connector, a retaining clip, and an end cap. If necessary, some other accessories can be configured.

1. Guide rail and sheath guide rail: It is made of aluminum alloy profile and is embedded with “U” shaped stainless steel slot to ensure the wear resistance and stability of the collector brush and good contact with the guide rail.

Sheath: The material is engineering plastic, which has wear resistance, aging resistance and flame retardancy, and can protect the guide rail with good insulation.

2. The collector adopts a supporting structure, and its function is to supply power to the mobile device, which is mainly composed of a special carbon brush, a binding post, a plastic shield and a support arm. If the equipment is to be repaired, the current collector should be powered off to ensure safety.

3. The connector is mainly used to connect the end of the guide rail, and the inside includes a pressure plate, a bolt, etc., the outer casing is made of engineering plastic, and a port is left on the outer casing, and the lead wire can be introduced.

4. Hangers, fixers, end cap hangers: mainly used to hoist the sliding line guide rails, the material is engineering plastics.

5. Fixer: It is mainly used to fix the slide rail guide. When the guide rail is stretched, the guide rail can be guided to extend to both sides of the fixer.

6, end cover: generally at the ends of the rail, from the insulation protection.

The five common maintenance knowledge is as follows:

1. The sliding line collector is a wearing part in the sliding line equipment system, so it needs to be checked regularly. When the carbon brush wears more than 2/3, it needs to be replaced. Especially for mobile devices with higher working frequencies, the probability of checking should be appropriately increased to avoid unnecessary trouble.

2. If the running track of the sliding line is long, the temperature compensator should be added according to the use environment, the length of the track and the number of equipment to avoid unnecessary damage to the sliding line caused by thermal expansion and contraction.

3. If two or more vehicles are used at the same time, it is recommended to install the maintenance section. When one equipment needs to be repaired, the power supply of the maintenance section can be disconnected to ensure the normal operation of the other vehicle.

4. It is necessary to periodically check the use of the sliding line. Generally, the sliding line needs to be tested once for one angle, and the angle brackets are kept parallel.

5. Check whether the accessories such as aluminum joints, joint sheaths and lifting brackets of each sliding contact line are in good condition and there is looseness. Replace if necessary. Before inspecting these accessories, be sure to cut off the main power supply to avoid unnecessary safety hazards.
