I have this image: I extracted lines using

    contours, hierarchy = cv2.findContours(image, cv2.RETR_LIST, cv2.CHAIN_APPROX_NONE)

I have 4 contours then. My goal is to convert this lines as infinite straight lines (so I can detect overlap points of those lines then. Is this somehow possible? I tried hough lines, but it gives unpredictable solutions, in some cases lines doesnt have enough length, or there is much more lines than just one.

You can use

Now you can find the intersection between equations.
