    摘要： A drone with railway driving capabilities has a drone body and at propeller arms. Each propeller arm has a propeller assembly having a propeller driven by a motor assembly. The propeller assembly of at least one propeller arm has a rotatably mounted propeller guard placed coaxially with the propeller. The propeller guard is shaped as a train wheel and is driven by the motor assembly. The propeller arm has an actuated joint for providing the propeller assembly with at least one rotation degree of freedom so that the propeller can be rotated between a flight mode and a driving mode and back. The flight mode involves a more horizontal orientation of the propeller assembly for providing an upwardly directed thrust force to the drone, in operational use, and the driving mode involves a more vertical orientation of the propeller assembly for allowing the respective propeller guard to drive on the railway track.

    摘要： A rail inspection device is provided. The rail inspection device includes: a drive part configured to drive on a lower rail; side wheels configured to rotate such that the drive part moves in a first direction on the lower rail, wherein the side wheels are provided on two side surfaces of the drive part opposite to each other in a second direction that intersects the first direction; upper wheels provided on an upper surface of the drive part and configured to rotate in contact with a branch guide rail provided above an upper portion of the drive part; a body connected to a lower surface of the drive part in a third direction that is perpendicular to the first direction and the second direction; and an inclination sensor provided on the upper surface of the drive part and configured to measure an inclination of the body.

    摘要： The present invention relates broadly to a railway track trolley (10) generally comprising a collapsible chassis (12), two pairs of wheels (14a/b) and (16a/b), and a platform assembly (18). The collapsible chassis (12) includes a pair of opposing beams member (20a) and (20b) interconnected by a pair of adjustable cross-members (22) and (24). The pair of wheels (14a) and (16a) are removably mounted to opposing ends of one of the beam members (20a) whereas the other pair of wheels (14b) and (16b) are removably mounted to opposing ends of the other of the beam members (20b). The railway tracks (26a) and (26b) may be separated at one of a plurality of predetermined track gauges and the collapsible chassis in an expanded condition is designed to match the required lateral separation of the opposing rail members (26a/b). The invention is also directed broadly to a gate catch assembly (90) generally comprising a coupling sub-assembly (92), and a catch sub-assembly (96) configured to be releasably engaged by the coupling sub-assembly (92). The gate catch assembly (90) may be installed in conjunction with the platform assembly (18) of the railway track trolley (10) of the earlier aspect of the invention.

    摘要： A device is for lubricating a railway switch, the device being remotely controllable and configured for moving on a railway track. The device has a container for lubricant and at least one nozzle configured for lubricating the railway switch with the lubricant. A system includes the device and a controller for remotely controlling said device. A method is for lubricating a railway switch, wherein the method includes the steps of remotely directing the device to the railway switch, remotely instructing the device to lubricate the railway switch, and remotely directing the device away from the railway switch to avoid hindering train traffic through the switch.

    摘要： A cable stay transport vehicle and inspection system having an upper frame coupled to a spaced apart lower frame. The transport vehicle is configured to be secured around a cable stay. The transport vehicle includes left upper and lower sets of wheels secured between left side upper and lower frames, and right upper and lower sets of wheels secured between right side upper and lower frames. In addition, a left steering device is coupled between the left upper and lower sets of wheels and includes a left steering gear, and a right steering device coupled to the right upper and lower sets of wheels and comprising a right steering gear. Left and right driving gears are coupled to the left and right steering gears, respectively, and are configured to engage the respective steering gear to turn the transport vehicle when activated.
