The wall-climbing robot can complete many tasks that are inconvenient for humans to work on vertical and inclined walls. The actual working wall is often uneven, and the wall-climbing robot needs to have the ability to overcome obstacles when walking. Therefore, the wall-climbing robot The structure of the walking device is complex, and at the same time it must have stability and the ability to overcome obstacles. Next, I will explain what are the walking devices of the wall climbing machine and how to walk.
1. Transmission device
The main executive parts of the transmission device are composed of drive device, position detection element, sensor, cable and pipeline. The transmission device includes two closed-loop arc-shaped guide rails arranged symmetrically about the center point, a rectangular threaded screw, and a guide slider. The front end has a transmission roller that matches the thread on the rectangular threaded screw; each adsorption foot module is connected to a guide The sliders are fixedly connected, and two adjacent guide sliders are hinged to each other, evenly distributed on the closed-loop arc guide rail, and each guide slider is slidingly connected with the closed-loop arc guide rail.
On the one hand, the walking mechanism needs to support the body, arm and hand of the robot, so it must have sufficient rigidity and stability; on the other hand, it must drive the robot to move in a wider space according to the requirements of the task. Generally, the walking mechanism needs to be able to move, position itself, balance itself, and have sufficient strength and rigidity.
1. Permanent magnet wheel
The permanent magnet wheel type is the easiest to think of, and the wheel is made into a magnet. Permanent magnets generally use RuFeB, which is also simple to implement. It is very similar to ordinary robot cars, except that the wheels are replaced with magnets.
2. Permanent magnet crawler
As the name implies, the permanent magnet crawler type uses a crawler mechanism. The crawler mechanism is similar to tanks and excavators. The advantage of the permanent magnet crawler type is that it can move in a more complex environment, such as curved surface obstacles. Magnetic crawler robots pass through curved surface obstacles. .
3. Permanent magnet gap type
The permanent magnet gap type still uses wheels, but the wheels are not permanent magnets. The permanent magnet is installed on the robot body, not in direct contact with the equipment, and has a certain gap with the equipment. In this way, the non-contact adsorption method reduces the running resistance of the wall-climbing robot, and achieves the effect of taking into account both the load capacity and the flexibility of movement. This method is used less, because the load capacity is generally not strong, and the control is more difficult.
However, permanent magnet wheel type or crawler type are generally used.
What are the walking devices of the wall climbing machine? The above is all the content introduced for you. I hope it can be helpful to you. The structure of the walking device of the wall-climbing machine is diversified. The wall-climbing robot designed and produced by Bihebifang Company uses different walking modes such as wheels and crawlers according to different working environments, which fully ensures that the robot can adapt to different working environments.
