Device for laying additional overhead communication lines

    We continue to review the activities of our Hackspace club.
    Inspired by the moral support of the habrosociety , we will talk about our developments.

    First of all, our developments are aimed not at toys, but at real mechanisms, robots that facilitate the work of installers, builders, developers, engineers, etc.

    The very first development of our club is a “scout” device designed for laying additional overhead communication lines between houses, poles, poles and also through power lines, using already laid cables and wires.

    Using the “Scout” laying or replacing outdated communication lines becomes an exciting activity, very simple. Only two installers are needed, one starts the device from one end, the other takes it. Due to this, time and labor costs are reduced.

    “Scout” is not replaceable when performing work on drawing an additional cable over busy streets and highways, without requiring their overlap. It is also necessary when laying cables through existing power lines, there is no need to agree on their disconnection.

    Analogues of such devices exist, but they are very bulky and heavy and have often been heard from installers that it is sometimes easier to manually drag the cable than to lift a heavy device.

    Our goal was to create a compact, not heavier than 2 kilograms and at the same time fully functional device with the possibility of remote control.

    We immediately plunged into work without bothering to look at analogues on the Internet, and this is probably the only case when this helped us. We have created a fundamentally new device in terms of design that are very different from analogues. And if you saw an analog before development, you would involuntarily repeat it.

    In the beginning, we just made a rectangular chassis, installed a roller there and connected it to the battery, at the first test we realized that no matter what material we made, it will slide when driving up, we need to make a pressure roller from the bottom. Well then, how to install the device on a cable? A mechanism was suggested for opening one of the rollers and snapping in. Moreover, the snap should be easy and at the same time not to open. The idea of ​​a snap mechanism was suggested by the mechanism of furniture hinges, in which there are two positions - open and closed, held in both positions by a spring. After assembly, another test and failure again. The scout dangles like a snot and constantly turns right and left and tries to jump off the rollers. How to keep it in the right position? And then one of us remembered the transmission on the discovery of dinosaurs, that dinosaurs rule their tail. Eureka, we attach the tail to our device, connect the other end of the tail through the ring to the cable through which the scout travels. Urrra rode smoothly and confidently. Subsequently, we replaced the tail with four stops that did not allow the scout to move left or right, well, in fact, two tails were made in front and behind.

    Field trials started, everything was successful, except when the spy was launched, there wasn’t enough cable to reach the next roof, and the “pusher” was moving and couldn’t stop him, I had to pull him back by the cable. And then there was a desire to make a remote control. A remote control device, a pair of rails, a remote control and our scout were purchased to be controlled from a distance. As a consequence, this remote control made life easier for installers.
