What are the components of the safe trolley line?

Today, we are the part of the safety wireline that we introduce to you. What are the components of the safety wireline?

First, the product structure: type trolley wire from the guide, sheath, collector, hanger, connector, clips, end caps and other components, according to user requirements can also be configured expansion section (thermal compensation device), maintenance section ( Isolator) etc.

Second, the collector: collector is a supporting structure, is the main component of power supply to mobile devices. It is made up of special carbon brush, terminal or terminal, plastic shield, support arm and so on. Apply proper contact pressure and slide smoothly along the guide rails to power the equipment. If the equipment needs to be repaired, the carbon brush of the collector can be pulled away from the rails to ensure power and safety.

Third, guide rail and sheath: The guide rail is made of aluminum alloy profile with good conductivity and adaptability to the environment (brand number 6063, state T5). The lower part of the guide rail is embedded with "V" shaped stainless steel groove to ensure that the collector brush slides along the groove. Wear, stability and good contact. The guide rail is generally 6 meters long. The sheath is composed of engineering plastics with toughness, wear-resistance, anti-aging and flame-retardant properties. It has good insulation protection for the guide rails and guarantees personal safety.

Fourth, the hanger, the holder and the end cap: The hanger is a special piece for hoisting and fixing the trolley rail guide. The retainer is a device that limits the guide rail to the bracket, and guides the guide rail to extend to both sides of the retainer when the guide rail is retracted due to a temperature change. The end caps are installed at the two ends of the guide rails for insulation protection. Hangers and end caps are made of engineering plastics.

V. Connector (composite power supply): The connector is designed for the connection between the ends of the guide rails. It is reliably connected by the pressure plate and bolts. The housing is made of engineering plastics as a protective cover. It also serves as a protective cover for the power supply device. The port can be introduced into the power supply line and fastened together with the connector pressure plate and bolts.

6. Inflation section (thermal compensation device): The expansion section, also known as the retractor, thermal compensation device, etc., is composed of a connector pressure plate, aluminum plate or copper plate with compensation power supply, leads, etc. The outer shell is engineering plastic. When the guide rail is retracted due to temperature changes, the gap is adjusted by the retractor to avoid deformation of the guide rail. Generally, when the length of the workshop exceeds 200 meters, a group is added for each additional 100 meters.

VII. Inspection section (isolator): The inspection section is made of connector platens and high-strength insulating materials. It is sheathed by a plastic casing. According to the needs of users, it is mainly convenient for maintenance and use such as trolley wires and mobile equipment.
