Rolling loads propulsion by pressurised supple tubes - uses force acting on walls of tube to propel trolley

摘要

The propulsion of rolling loads by pressurised supply tubes uses the force acting an the exterior wall of the tube from the internal pressure of a gas or liquid to push the load along. The line of the tube can be open or closed and placed on the ground or supported in the air. A hollow sectioned square trolley is provided internally with two pressure rollers (2) (2'), between which the tube (1) is supported, and four tube guide rollers (8). The exterior of the trolley has eight horizontal rollers and eight lateral guide rollers which support the trolley in guides. The underside of the trolley has a pin (5) which locates in jaws attached to a load carrying trolley (6) which runs on tracks.
