Cable reel principle and classification performance characteristics

In our daily life, we often use cable reels, such as some trams, hydraulic machinery, and gantry cranes. So what is it used for? What is its working principle?

Cable reel

Cable reels are also known as cable reels or cable reels. It is mainly used to install in a small space, and it has the characteristics of easy maintenance and low cost. It replaces the previous sliding contact line, and now it has become the mainstream in the field of mobile transmission.

Cable reel classification

The cable reel can be divided into two categories: non-electric and electric; according to its arrangement, it can be divided into two types: axial single row and axial multiple rows; according to the different positions of the electric slip ring There are two types of internal slip ring and external slip ring; according to the winding material, it can be divided into cable reel and hose reel.

Principle and performance characteristics

Cable reels can be divided into multiple types in different ways. Different types of cable reels have different working principles. Let's take a look at their working principles with Xiaobian.

1. Elastic cable reel

Working principle: Its working principle is very similar to the tape measure. It uses the spring force of the cable reel to wind up its cable. When we use the cable, its spring will tighten and the cable will be pulled out, and when released, the cable will automatically wind up.

Performance and characteristics: This device is relatively easy to install, and the synchronization performance is also good, but the cable tension is relatively small, so the service life of the spring will be relatively short.

2. Heavy hammer cable reel

How it works: The weight-type cable reel raises the weight to a certain height to store energy. When using the cable, the cable reel is rotated out of the cable by adjusting the height of its weight.

The performance characteristics are that its structure is relatively simple, the performance is stable and reliable, and it is easy to install and maintain.

3. Magnetically coupled cable reel

Working principle: This is to adjust its cable reel at differential speed. When the device used is getting closer and closer to the ground, the cable will be reeled under the force, at this time, we must pay attention to ensure that its speed is uniform. When the device moves away from the cable on the ground, the cable is released.

Performance characteristics: The speed of the magnetically coupled cable reel is relatively low, there is no heat phenomenon, and the tension of the cable can be adjusted, which can effectively protect the cable. However, it is not suitable for the use of axial single row, it will cause the appearance of dry sound.

to sum up

In addition to the above-mentioned cable reels with different working principles, there are actually many types, such as hysteresis cable reels, frequency-controlled cable reels, etc.
