An unmanned rail vehicle for surveillance, inspection, and/or maintenance of an industrial site is provided. The rail vehicle includes at least two carry rollers adapted for engaging on an upper rail side of a rail, wherein the center of gravity of the rail vehicle is vertically below the upper rail side; and at least one support roller connected to the chassis and adapted for rolling against a lateral rail side of the rail to laterally displace the center of gravity of the rail vehicle with respect to the upper rail side.

This disclosure discloses a braking-recovery system and method for a train, and a train. The system includes: a traction network, a train, and an energy storage power station. The energy storage power station is connected to the traction network, the energy storage power station includes a second controller, and the second controller controls the energy storage power station according to the voltage of the traction network to perform charging or discharging. The train includes: an electric brake; a battery; a distributor, connected to the electric brake, where there is a node between the distributor and the electric brake; a bidirectional DC/DC converter, where one end of the bidirectional DC/DC converter is connected to the battery, and another end of the bidirectional DC/DC converter is connected to the node; and a first controller, used to control, when the train is braked, the distributor and the bidirectional DC/DC converter to feed back braking electric energy of the train to the traction network, and control the bidirectional DC/DC converter according to a voltage of the traction network to absorb the braking electric energy of the train by using the battery.

For a monorail guide beam adapted to support a monorail car traveling a distance along the monorail guide beam, the guide beam having a generally horizontal upper surface and two opposed, generally vertical side surfaces, the guide beam having a preferred width between the side surfaces along the distance, a beam measuring device for measuring an actual width between the side surfaces of the monorail guide beam along the distance is disclosed.

The present disclosure discloses a rail transport system. The rail transport system includes: a rail, the rail includes a steering portion and a travelling portion, the travelling portion is connected to the steering portion, and a first recess is constructed on the travelling portion to form an escape passage; and a rail vehicle, where the rail vehicle includes bogies and a vehicle body, the bogie movably straddles the rail, the bogie fits in with an inner bottom surface of the escape passage of the travelling portion and the steering portion, and the bogie travels by using the travelling portion and is steered by using the steering portion, and the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail. The rail transport system according to this embodiment of the present disclosure has advantages such as facilitation of evacuation of passengers in an emergency, low costs, small occupied space, small rail weight bearing, and high stability.

A dead axle of a rail vehicle, a rail vehicle, and a rail transportation system are provided. The dead axle of a rail vehicle includes: an axle body; a running wheel; a guiding frame; a horizontal wheel; and a connecting rod component, including a first transverse pull rod and a second transverse pull rod, where when the rail vehicle turns left, the horizontal wheel cooperates with a rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the left, and when the rail vehicle turns right, the horizontal wheel cooperates with the rail beam to drive the guiding frame to swing and drive the first transverse pull rod to move together, and the second transverse pull rod is driven by the first transverse pull rod to drive the running wheel to swing to the right.

A first wheel supporting portion of a stacker crane is fixed to a travelling vehicle main body to be pivotable in the horizontal direction. A first drive wheel is supported by the first wheel supporting portion and is able to contact one side surface of a lower guide rail. A lock mechanism fixes the first wheel supporting portion to the travelling vehicle main body so that the first wheel supporting portion cannot pivot. A second wheel supporting portion is fixed to the travelling vehicle main body to be capable of pivoting horizontally. A second drive wheel is supported by the second wheel supporting portion and is able to contact with another side surface of the lower guide rail. A pressing mechanism presses the first and second wheel supporting portions such that a distance between the first wheel supporting portion and the second wheel supporting portion is reduced, to cause the first and second drive wheels to laterally clamp the lower guide rail. Pressing of the pressing mechanism is capable of being released.

The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. The cartridges may be assembled by transporting carriages between various substations at which parts are added to a base. In another assembly method, the base may be moved between a plurality of robots which direct the base downwardly into contact with components to couple the components therewith. An inspection system may inspect the cartridges at various stages of completion.
