Track-changing device for a pneumatic transport vehicle

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. The vehicles travel over railway tracks laid over an elevated track supported by pillars. The center of the top of the superstructure of the elevated track has a longitudinal slot with seal by means of which the mast of the propulsion plate is allowed to move freely along the path of the vehicle. In the superstructure of the turnout beams there are mounted the mobile rails with their respective drive mechanisms and locking. A section isolation valve is positioned inside the propulsion duct of the turnout beams.

Segment isolating valve for pneumatic transport system

Segment isolating valves assembled on the lower back of the elevated guideway (1), the plug base (2) being hinged on a housing (3) fixed to the elevated guideway (1) by a flange (4) for fast connection and disconnection. The housing (3) is equipped with a rainwater runoff tank (5). The segment isolating valve comprises a plug (2) mounted in a housing (3) affixed to the elevated guideway by means of a flange (4) for fast connection and disconnection. The plug (2) is moved by means of a linear actuator (6), whose rod exerts force on an articulation (7), which is pivoted above on the plug (2) and below on a frame (8) affixed to the housing base (3). The assembly is mechanically locked through a closed position locking cam (9), displaced automatically by springs (10). A safety locking pin (11) is actuated by a release solenoid (12).

Kinetic energy converter for a pneumatic transportation system

The kinetic energy converter is coupled to a bogie of a pneumatic propulsion vehicle for a transportation system of passengers and cargo. The kinetic energy converter (6) is mounted in at least one of the axle sets (4) of the bogie structure (1). The kinetic energy converter (6) is comprised of an electric generator provided with a housing (10) where an electric generator rotor (16) spins, provided with a rotor pulley (15) moved by a belt (11) driven by a freewheel pulley (14) mounted on a drive shaft (13) provided with shaft ends (25) which are mounted onto wheel hubs (24) of the bogie structure (1). The axle set (4) is comprised of guide tubes (7) whose internal ends have flanges (8) which are connected to the supports (9) of the electric generator housing (10).
