[0030] In one embodiment, the surface of the upper base 3 is provided with a counterweight 1 arranged on a counterweight shaft 16 which is vertically fixed to the surface of the upper base 3 to prevent the railcar from overturning due to the weight on one end. In one embodiment, a warning light 13 is vertically installed on the railcar upper platform 12 of the railcar to warn the running state of the railcar.

[0031] In order to effectively limit the running stroke of the railcar and prevent derailment caused by incorrect operation or loss of control, a first stroke limiting switch 8 and a limiting block 7 (terminal physical limiting block) are arranged at both ends of the track.

[0032] In order to rotate the cantilever arm to realize sleeve rod molding, the cantilever arm includes a funnel-shaped cantilever arm pressure plate 17 for containing sleeve rods, and the bottom of the funnel-shaped cantilever arm pressure plate is fixed on a cantilever arm support frame 19 formed by welding steel pipes.

Wherein, the periphery of the upper base is also provided with a threaded interface for installing and connecting the protective cover.

[0037] The funnel-shaped pressure bearing plate in the form of a groove on the cantilever arm of the present application can load 16 sleeve rods (each sleeve rod is 22 kg) at most at one time, and when the weight and length of the sleeve rod change, the working cycle can be set through programming, so that the funnel-shaped pressure bearing plate is full / close to full when it starts to transport the sleeve rod, so that the efficiency is maximized and the adaptability is strong.

[0038] The rotating disc at the rear end of the cantilever shaft of the present application is a cam structure, and two stroke limit switches are arranged to limit the rotation of the cantilever shaft in the range of 0-135 degrees, so that the funnel-shaped pressure bearing plate in the form of a groove can make the sleeve rod slowly fall along the circular arc bevel when loading and discharging.
