Installation Type
Horizontal cable installation
- You can qualify in 1 or 2 directions.
- The cable is dragged on a continuous plane or supported by an interval of less than 1 m.
- Installation height from the cable drag the plane to the center of the roll no more than 1 meter.
- do not consider cable steering
- Operating speed: 10 m / min - 60 m / min
- maximum acceleration up to 0.3 m / s & sup2;
Vertical cable installation
- Reel installed at the top
- The cable appears in a vertical direction
- Operating speed: 10 m / min - 40 m / min
- maximum acceleration up to 0.3 m / s & sup2;
- Free droop cable length L0 is not considered.
Working principle
When moving equipment such as a trolley or a moving device such as a car, pull the roll and release the cable. At this time, the flat scroll coil is wound on the mandrel and the spring stores energy. When the electrical equipment to return, the spring force, the drum in the opposite direction of rotation, synchronous winding cable.
Structural features
1, to flat scroll spring as a driving force, no power consumption, safe and reliable work.
2, the use of slip slip - carbon brush frame structure to transfer power, power supply continuous smooth.
3, set the reversible body, to avoid reversing the reel and break the spring.
4, simple structure, installation, commissioning, easy maintenance.
Main product model
1, DJ1 series: the use of chain drive, an increase of product plasticity, according to the user's requirements for the use of spring configuration and chain transmission ratio, the cable force appropriate.
2, DJ2 series: with a compact, small size, light weight, easy installation and so on. Widely used in electric flat car, mobile car amount, electric grab and other mobile electrical equipment.
3, DJ5 Series: The product is made of plastic shell, compact structure, belonging to the mini spring-type cable reel, mainly for the current below 10A, the moving distance of 10 meters, and the installation of small space occasions.
4, JT1 series: spring frame, reel and slip ring device split design, the cable reel is more stable, easy maintenance.
5, JT2 series: mainly used for current below 50A, moving distance in the range of 30 meters. The main features and structure are similar to DJ2
Spring reel selection requires parameter editing
· Installation type
• Cable parameters: diameter, weight per meter, minimum bend radius (= radius of drum)
• Determine the required cable core size according to the rated current, the maximum temperature, and the maximum number of cable layers.
• Note that the number of cable layers can affect the correct selection of the cable.
• Calculate the roll roll length based on the supply point position and the travel length.
• The additional cable length (and mounting position) is used to calculate the required cable length.
• Speed, mounting height, and power supply (terminal or intermediate) to select the spring. (Power supply point to be able to withstand enough tension
