TRACK-CHANGING DEVICE FOR A PNEUMATIC TRANSPORT VEHICLE
20220119018 · 2022-04-21 ·

The present invention refers to an improvement developed on a pneumatic transport system for loads and/or passengers whose vehicles are not provided with on-board drive means, being guided on two exclusive tracks arranged in parallel, each track being dedicated to one travel direction, resulting in high transport capacity. The vehicles (1) travel over railway tracks (5) laid over an elevated track (6) supported by pillars (7). The center of the top of the superstructure of the elevated track (6) has a longitudinal slot (9) with seal (8) by means of which the mast (3) of the propulsion plate (4) is allowed to move freely along the path of the vehicle (1). The crossbeam is comprised by four beams which constitute the superstructure of the elevated track, being two turnout beams (6′) and two straight beams (6), whereby the four beams are permanently connected to each other and to the pillars (7) in the region of the heads to form a monolithic hyperstatic structure. In the superstructure of the turnout beams (6′) there are mounted the mobile rails (16, 18 and 21) with their respective drive mechanisms (17, 19 and 20) and locking (15). A section isolation valve is positioned inside the propulsion duct (12) of the turnout beams (6′) and is comprised of a shutter (40) and a linear actuator (41) which activates a set of two articulated rods (42) to the position of the limit stop (43).

High speed transportation in running tube as running rail
11220278 · 2022-01-11 ·

A high-speed transportation device with a tube as a rail, including a tube structure, a carrier structure, a control system, a braking system, and a drive system. The tube structure is an extension structure surrounded by a tube wall. The tube wall is provided with a plurality of unidirectional airflow windows configured to control a flowing direction of airflow. The carrier structure operates in the tube structure. The carrier structure is a carriage-type structure. The unidirectional airflow window installed on the tube structure of the invention can significantly reduce the air resistance of the operational system. Compared with the current rapid transportation device, this invention has the advantages of high efficiency, low cost, fast speed and high safety, and can be used for the development of new rapid transportation system.

METHOD OF INTELLIGENTLY MANAGING PRESSURE WITHIN AN EVACUATED TRANSPORTATION SYSTEM

A high-speed transportation system comprises an evacuated travel conduit divided into a plurality of segments by closable gates, and associated with corresponding segment pumps that maintain operating vacuums within the segments when vehicles are present. When a segment is unoccupied, energy is saved by closing the adjoining gates and deactivating the associated segment pump, thereby deactivating the segment and allowing the segment's internal pressure to rise due to leakage. As a vehicle approaches, the segment pump is reactivated, lowering the internal pressure to the operating vacuum, and the gates are opened. Embodiments include a boom-tank system that can accelerate re-evacuation of a segment having an increased internal pressure by establishing fluid communication with at least one recently deactivated segment having a lower internal pressure. As a vehicle transits the conduit, a rolling, contiguous group of activated segments surrounding and in advance of the vehicle can be maintained.

LINEAR TRANSPORT APPARATUS

A linear transport apparatus includes a transport cart, a first roller that rotates about a first rotation shaft extending from the transport cart along a first direction, a second roller that rotates about a second rotation shaft extending from the transport cart and forming an acute angle with the first rotation shaft, and a rail sandwiched between the first and second rollers to extend along a track on which the transport cart moves. The rail includes a first contact portion coming contact with the first roller and restricting movement of the transport cart in a second direction perpendicular to a direction in which the rail extends and the first direction, and a second contact portion that comes into contact with the second roller and is parallel to the second rotation shaft, and the rail includes a portion in which curvature of the track moves is different from another portion.
