Principle and characteristics of multistage tube safety sliding contact line

Multi-stage tube safety sliding contact line can be used in factories, mines, warehouses, stations, ports and other places lifting machinery such as: electric hoist, beam and bridge cranes.

(I) main components and their working principles:The power supply safety sliding contact wire device is composed of two main components, the guide, and some auxiliary components:

1. Catheter: it is a semi-closed special-shaped tubular part, which is the main part of the safety slip contact line. The inner part can be embedded with 2-9 naked guide rails as the power supply conductor according to the needs. The guide rails are insulated from each other and the outer shell, so as to ensure the safety of power supply. And in the live maintenance of the maintenance personnel effectively prevent electric shock accident. The length of each tube of our factory is 4m, which can be connected into any length required. Generally, the tube is made into a straight line, and can also be made into a circular arc according to special needs.

2. The electric guide is a set of brush shell frames running in the conduit, which are driven by the pulling fork (or traction chain, etc.) placed on the electric power mechanism (truck, car, electric hoist, etc.) to run synchronously with the electric power mechanism, and transmit the electric energy of the brush to the motor or other control elements through the guide rail. The guide brush has 3-16 poles corresponding to the number of guide rails in the tube.

(ii) Product features:

1. Safety: power supply safety sliding contact wire housing is made of engineering plastics with high insulation performance. The enclosure can be rated ip13.p55 as needed to protect against rain, snow, frost and frost attacks as well as foreign matter. The product is experienced in a variety of environmental conditions. Good insulation performance, no damage to the maintenance personnel touching the outside of the transmission conduit.

2. Reliability: the transmission guide has excellent conductivity, fast heat dissipation, high allowable current density, low impedance value and small line loss. The brush is made of copper and carbon alloy materials with high conductivity and wear resistance. The conduction is flexible in movement and has good directional performance.

3, economic: power supply safety sliding contact line device structure is simple, allow high current density, low resistivity, low voltage loss, can save about 10% of electricity, to achieve the replacement of steel with plastic, to replace copper with plastic, innovative design, no other insulation structure, no compensation wire, installed in the same side of the crane control room. Save installation materials and expenses.

4. Convenience: the power supply safety sliding contact wire device integrates multi-pole bus into one catheter, which is easy to assemble. Its fixed bracket, connecting clip, suspension device, are supplied with common parts. Installation and disassembly, adjustment, maintenance is also very convenient.

(Ⅲ) purpose:Power supply safety sliding contact line device can be used for electric hoist, electric beam and standard crane: stacking machine, automatic inspection line of mechanical and electrical products, automatic production line; Mobile power tools and other mobile conductive equipment, as well as factories, mines, workshops, office fixed laying bus slot.
