[TC28] Oil Pumpjack

[Dzmitry]

After university, I worked as a geophysicist for six years. As a result, my usual work scenery often consisted of oil pump fields.

So when I read about a competition for non-transport mechanisms, I didn’t have to think long.

The first thing I decided to assemble was the beam and the horse's head. After putting the entire structure together, I had no regrets about how I connected them.

I had to spend a long time adjusting the beam's connection angles to effectively convert its rocking motion into the linear movement of the rod.

The second part of the assembly was the beam support. I decided to abandon vertical supports and made them inclined toward the beam. Then, I added a maintenance platform and a ladder running along the entire support.

The crank-slider mechanism made me spend a lot of time selecting the proper height for the crank attachment point, its length, and the length of the connecting rod to ensure the beam oscillated within the desired range.

I didn’t expect the counterweight to have such a significant impact on the uniformity of the entire structure’s movement—it was a real discovery.

I quickly added the motors, and the only question left was: where should I place the battery pack?

I had long thought that the shape of the battery pack resembled a transformer booth, which inspired the solution—to create a transformer and power line supports to supply energy to the pumpjack. 

Finally, I put everything together!

Nice. Something completely different!

Interesting project. Legacy of our Croatian  inventor lives even with Lego

Really nice use of the banana gear!
