As important equipment in the cable industry, cable coiling machines and related winding equipment indeed have specific technical requirements during the installation process. Correct installation not only affects the service life of the equipment itself but also directly impacts cable protection effectiveness and operator safety.

This article provides an in-depth analysis of the professional conditions and standards for cable coiling machine installation, offering practical guidance for industry practitioners.

Basic Installation Conditions for Cable Coiling Machines

The installation environment of cable coiling machines directly affects their stable operation and service life.

According to industry standards, cable coiling machines have clear requirements for usage environmental conditions: the altitude should not exceed 2000 meters, and the ambient temperature range should be between -20°C and 45°C.

Equipment can be installed in locations that allow rain, splashing water, and non-corrosive gas and dust, but it is necessary to ensure that the collector box's protection level reaches IP54.

In terms of foundation preparation, before installation, reference should be made to the foundation drawing dimensions to prepare the foundation and reserve holes for anchor bolts.

Only after the foundation has solidified can equipment installation begin. The positions of anchor bolt holes for each component need to be determined on-site according to the actual matching dimensions before cement is poured for fixation.

Installation precision is a core requirement in cable coiling machine installation. According to GB 50967-2014 "Code for Installation of Coking Machinery and Equipment," when adjusting the drum levelness, the allowable deviation should be 1/1000 of the drum length.

At the same time, it is necessary to adjust the horizontal deviation of the drum relative to the baseline of the track, with an allowable deviation of 1.0 mm.

Cable reels also have strict standards for parallelism and verticality: the parallelism between the cable and the drum's outgoing line and the track centerline should be less than 3 mm within the cable reel diameter, the deviation between the cable guide frame center and the cable reel centerline should not exceed 3 mm, and the guide frame must remain vertical.

Key Specifications for Cable Installation

The installation quality of the cable itself is equally important, as it directly affects the cable's service life and safety performance.

During cable laying, to prevent damage to cable insulation, the cable should not be bent excessively.

The cable should be led out from the top of the reel, and the cable should not be dragged or rubbed on brackets or the ground. The cable should not have uncompensated mechanical damage such as flattened armor, twisted cables, or broken protective layers.

Professional specifications require that cables must be wound on the equipment reel without twisting.

For cables with an outer diameter less than 21.5mm, the inner bending diameter should be 10 times the cable diameter; for cables with an outer diameter greater than 21.5mm, the inner bending diameter should be 12.5 times the cable diameter.

In places where mechanical damage may occur, such as entering buildings, tunnels, passing through floors and walls, and from trenches to poles, equipment, and wall surfaces, the section of cable within 2 meters from the ground height must be protected by pipes or protective devices.

The inner diameter of the protective pipe should be 1.5 times the outer diameter of the cable, and the protective pipe should be buried not less than 100 mm into the ground.

There are special requirements for mechanical cable laying: the maximum pulling strength should comply with regulations, and when using steel wire rope for pulling, the total pulling force for high-voltage and extra-high-voltage cables should not exceed 30 kN.

The laying speed should not exceed 15 meters per minute. When laying high-voltage and extra-high-voltage cables, the speed should be appropriately slowed down, generally not exceeding 6 meters per minute.

Debugging and Maintenance Points

Debugging work after installation is an indispensable step to ensure the normal operation of the cable coiling machine.

Cable tension adjustment is crucial - after the trolley travels, the cable tension needs to be adjusted to a moderate level, so that the distance from the starting point where the cable contacts the ground to the center of the cable guide frame is 3-4 meters.

Otherwise, the hysteresis coupling should be adjusted to change its output torque so that the cable tension meets the requirements.

When the trolley stops traveling, the check device located between the motor and the hysteresis coupling should ensure that the cable reel does not rotate due to the weight of the cable or inertia.

During operation, if the cable will cross the entry point and the entry point is below the ground, an appropriately sized compensation pulley must be used, equipped with a funnel-shaped guiding device, winding one to two turns of cable.

Lubrication management is the guarantee for long-term stable operation of the equipment. Each unit of the cabling machine uses local lubrication, and the staff should frequently observe the oil level from the oil sight hole and replace the oil in the box in time.

The bearings of each transmission shaft need to be filled with calcium-based lubricating grease, and multiple lubrication points including the twisting cage transmission box, angle box, and reducer need regular maintenance.

After 1000 hours of production, each gearbox needs to be cleaned and refilled with new oil, and thereafter new oil should be replaced every 12 months. Parts with relative movement (such as slideways, screw rods, open gear pairs, etc.) need to be oiled once before each shift's production.

Safety Operation Specifications

Safety is the primary consideration during the installation and operation of cable coiling machines.

During cable handling, to avoid rolling the cable reel, the cable should be transported directly to the site. The cable reel must be unrolled before installation, and during the unrolling process, it can only be taken from the top of the cable reel.

If there is not enough space to place the entire length of the cable, the distance between the cable reel and the equipment reel should be as long as possible, which can avoid generating S-bends and other deviations during laying.

Large-ratio cable clamps must be used to fix the end of the cable to avoid squeezing the cable.

When the cable is fully pulled out, at least two turns of cable must be retained on the equipment cable reel. During installation and operation, the cable must be protected from external damage.

Moving the cable to the installation site should use appropriate cable pulleys and trolleys. In special cases where it is necessary to rotate the cable drum, it must be rolled in the direction indicated by the arrow.

During equipment operation, do not pull the cable on devices that are too tight or too loose. During the unrolling process, the cable can only be taken from the top of the cable reel. Finally, ensure that the cable is without twists, and adjust the cable so that it hangs loosely in the middle of the cable support frame.

Precise installation and professional maintenance are the cornerstones of stable operation for cable coiling machine equipment. From leveling correction to tension adjustment, from lubrication management to safety protection, every link carries the dual responsibility for equipment lifespan and personnel safety.

For practitioners in the cable industry, mastering these installation conditions is not only a requirement for technical operations but also a reflection of professional competence. Only by adhering to professional standards in every detail can we ensure that the cable coiling machine system always maintains optimal performance during long-term operation.
