Title: Rolf Stoltz: Innovator in Tunnel Technology
Introduction
Rolf Stoltz is a notable inventor based in Bottrop, Germany. He has made significant contributions to the field of tunnel technology, holding a total of 2 patents. His innovative designs have improved the efficiency and functionality of cutting and winning machines used in tunneling operations.
Latest Patents
One of Rolf Stoltz's latest patents is for a cutter bit assembly. This cutter bit features a generally cylindrical shank and a conical cutting head. The shank is designed to be rotatably received within a matched bore in a bit holder. A reduced-diameter portion on the shank allows for the mounting of a bearing ring, which is gripped by a compressible locking ring. This design ensures that the locking ring frictionally engages the bore in the bit holder, preventing relative axial movement between the cutter bit and the holder.
Another significant patent is for a method and apparatus for controlling the advance of a tunnel drive. This apparatus is designed for tunnel drive shields that utilize elongate implements supported and guided on a frame. Hydraulic rams are employed to move the planks relative to the frame. The control apparatus includes hydraulic ram means that act between the frame and the permanent tunnel lining, allowing for precise control of the frame's advance by varying the pressure of hydraulic fluid applied to the hydraulic ram means.
