This utility model relates to the technical field of material handling, and in particular to a transfer trolley for hoisting materials, comprising: a trolley body, an axle, wheels, and a power unit. The power unit is installed in a cavity inside the trolley body and is connected to the axle for transmission, thereby driving the axle to rotate, which in turn drives the wheels to rotate. Inductive switches are also installed at both ends of the trolley body, and these switches are electrically connected to the power unit. When the trolley body moves to a preset position under the drive of the power unit, the inductive switches sense the preset position and send a corresponding sensing signal, causing the power unit to stop driving the trolley body to move. In summary, the transfer trolley can transport heavier materials and transport them in batches via pods. Precise stopping and automated control are achieved through inductive switches, and the dovetail base is compatible with existing standards, allowing for quick installation of pods, thus improving transport capacity, automation level, and flexibility.

This utility model relates to the field of track-mounted conveyor technology, specifically a track-mounted conveyor with a protective structure, comprising: a hopper and a track. An extension plate storage slot is provided on the protective plate, into which an extension plate is movably inserted. A support rod mounting slot is also provided on the protective plate. The beneficial effects are: the extension plate extends out of the extension plate storage slot, increasing the single-load transport capacity of the hopper; after the hopper transports materials to its destination, workers use shovels to unload materials from the hopper that are higher than the top of the protective plate, causing the end of the support rod that was originally inserted into the extension plate storage slot to retract into the support rod mounting slot. Then, the handle is released downwards, causing the extension plate to retract completely into the extension plate storage slot, thus reducing the height of the protective plate. This achieves the goal of increasing the single-load capacity of the hopper while making it easier to unload materials located at lower levels in the hopper.
