The vehicle body structure comprises a vehicle roof, side walls, a bottom frame and end walls, the tops of the side walls are connected with the vehicle roof, the bottoms of the side walls are connected with the bottom frame, and the end walls are arranged at the two ends of the bottom frame in the extending direction and connected with the vehicle roof and the bottom frame correspondingly; wherein the roof, the side walls, the underframe and the end walls are all of sandwich structures. According to the vehicle body structure, the vehicle roof, the side walls, the bottom frame and the end walls are all of the interlayer structures, compared with an existing vehicle body structure which adopts a plate beam connecting structure, the number of parts is greatly reduced, the weight of the vehicle body structure can be reduced, and the lightweight design of the vehicle body structure is achieved; meanwhile, the manual operation amount of workers can be reduced, and the automatic production efficiency is improved.

Loading granulated metallic units (GMUs) into railcars, and associated systems, devices, and methods, are disclosed here. In some embodiments, an apparatus for loading GMUs into a railcar comprises a housing unit, a weigh bin, a weigh bin gate, a hopper, and an articulating chute. GMUs in the weigh bin are discharged via gravity through the weigh bin gate when the weigh bin gate opens. The hopper is configured to guide GMUs received from the weigh bin to the articulating chute. The articulating chute is angled and rotatable about an axis of the hopper such that, when rotated, the end of the chute is closer to the floor of a railcar. In some embodiments, the chute includes telescoping segments.

The utility model relates to the technical field of railway inspection, in particular to a railway track inspection operation trolley which comprises a bearing plate, power wheel structures are hinged to the two ends of the bearing plate, each power wheel structure comprises an overturning plate, a limiting frame is fixed to one end of each overturning plate, a motor is fixed in each limiting frame, and track wheels are fixed to the output ends of the motors. A tensioning rod is fixed to one side of the limiting frame, limiting grooves are formed in the two sides of one end of the tensioning rod, connecting blocks are slidably arranged in the limiting grooves, compression springs are clamped between the connecting blocks and the limiting grooves, connecting ends are fixed to the lower side of the bearing plate, connecting holes are formed in the side faces of the connecting ends, and two baffles are fixed to the positions, close to the two sides, of the upper side of the bearing plate. A clamping plate is hinged to the baffle on one side, a clamping groove is formed in the upper side of the baffle on the other side, and the other end of the clamping plate is clamped in the clamping groove. The railway inspection trolley solves the problems that an existing railway inspection trolley is large in structure, large in occupied space, complex in structure and high in manufacturing cost.

Reduced-waste systems and methods for granulated metallic units (GMUs) production are disclosed herein. A representative method can include receiving a first supply of molten iron and producing GMUs by granulating the molten iron poured onto a target material of a reactor. The method can include removing residual fines of the GMUs via a classifier based on a threshold particle size and mixing the residual fines with a second supply of molten iron to produce additional GMUs.

The invention discloses a vehicle body structure and a railway vehicle. In the vehicle body structure, the size of the cargo inlet / outlet along the length direction of the vehicle body is greater than 3m; the first frame provided with the cargo inlet and outlet comprises a traction beam, a lower side beam and a traction beam which are sequentially connected in the length direction of the vehicle body, the middle section area of the lower side beam limits the lower boundary of the cargo inlet and outlet, the lower side beam is in a channel steel type, an opening of the channel steel type lower side beam faces the first frame on the opposite side, and the upper boundary of the channel steel type lower side beam is horizontally arranged. The size of the middle area of the channel steel type lower side beam in the height direction of the vehicle body is larger than that of the two ends of the channel steel type lower side beam in the height direction of the vehicle body, and a section with the size monotonically increasing in the height direction of the vehicle body does not exist from the position, with the largest size in the height direction of the vehicle body, of the channel steel type lower side beam to any end area. The first frame on the side provided with the goods inlet and outlet further comprises a lower side beam inner sealing plate for sealing an opening of the channel steel type lower side beam. The device is suitable for transportation of large-size goods.
