Description

Technical Field

[0001] This utility model relates to the field of bogie frame support technology, and in particular to a support bracket for a railway freight car bogie frame. Background Technology

[0002] During maintenance, railway freight car bogies are disassembled into their frames. Due to their weight and the presence of crossbars in most models, these frames are often placed directly on the ground. While this placement method is acceptable for manual transfer using forklifts, it is inadequate in intelligent transportation systems. When using heavy-duty AGV (Automated Guided Vehicle) transfer frames, the low height of the frame's bolster and the presence of crossbars prevent heavy-duty AGVs from accessing the space beneath the frame to perform lifting and lowering operations, thus failing to meet the demands of intelligent transportation. Currently, there is a lack of suitable support brackets for heavy-duty AGV intelligent transportation, specifically for railway freight car bogie frames with crossbars, which fails to meet the requirements of heavy-duty AGV intelligent transfer frames. Designing a support bracket for railway freight car bogie frames that meets the requirements for heavy-duty AGV intelligent transfer, including for railway freight car bogie frames with crossbars, is a technical problem urgently needing to be solved by those skilled in the art. Utility Model Content

[0003] To address the current lack of a suitable support bracket for heavy-duty AGV intelligent transportation and applicable to railway freight car bogie frames with crossbars, this utility model provides a railway freight car bogie frame support bracket. By using workpiece support blocks to lift the bogie's bolster, contact with the frame's crossbars is avoided, while multiple degrees of freedom of the frame are restricted, ensuring reasonable support for the frame. This provides stable and reliable support, and the hollow design of the bracket makes it suitable for heavy-duty AGV intelligent transportation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a railway freight car bogie frame support bracket, including positioning supports, workpiece supports, baffles, a material rack, a material plate, hexagonal head bolts, positioning and fixing blocks, rubber buffer pads, anti-slip pads, etc. Two workpiece supports are used to support the bogie's bolster and limit the horizontal displacement of the frame. Two baffles serve as safety protection components to prevent the frame from sliding directly to the ground due to inertia. The workpiece supports and baffles are arranged symmetrically at 90° to avoid contact with the frame's crossbars. The hollow material rack facilitates the entry of heavy-duty AGVs into the bottom space of the frame to complete lifting and lowering operations.

[0005] The aforementioned railway freight car bogie frame support bracket has a bottom positioning support that is rigidly connected to the upper surface of the material plate by an internal hexagonal head bolt, and a top positioning support that is rigidly connected to the bottom of the workpiece support block by an internal hexagonal head bolt. The positioning support has three ribs, and two positioning supports are symmetrically arranged along the center line of the short side of the material plate.

[0006] The aforementioned railway freight car bogie frame support bracket has a concave shape at the contact point between the workpiece support block and the frame bolster, and the contact part is a fixed rubber buffer pad, which can reduce the collision between the frame and the workpiece support block. Limiting plates are located on both sides of the rubber buffer pad, which can limit the horizontal displacement of the frame.

[0007] The above-mentioned railway freight car bogie frame support bracket has a bottom baffle rigidly connected to the upper surface of the material plate by an internal hexagonal head bolt, and the two baffles are symmetrically arranged along the center line of the long side of the material plate.

[0008] The aforementioned railway freight car bogie frame support bracket has a material plate rigidly connected to the material frame by welding. The lower surface of the material plate is rigidly connected to the positioning and fixing block by hexagonal head bolts. Circular holes are symmetrically distributed at the four corners of the material plate. The positioning and fixing block needs to be adjusted after assembly to match the lifting pin of the heavy-duty AGV.

[0009] The aforementioned railway freight car bogie frame support bracket has a hollow bottom, which facilitates heavy-duty AGVs to enter the bottom space of the frame to complete lifting and raising actions. The part of the frame that contacts the ground is fixed with an anti-slip pad.

[0010] The beneficial effects of this utility model are that it uses workpiece support blocks to support the bolster of the frame, while limiting the horizontal displacement of the frame. It uses two baffles as safety protection components to prevent the frame from sliding directly to the ground due to motion inertia. The workpiece support blocks and baffles are arranged symmetrically at 90° to avoid contact with the frame's cross bars. The hollow material rack facilitates the entry of heavy-duty AGVs into the bottom space of the frame to complete lifting and raising actions. It effectively solves the current problem of lacking a load-bearing support suitable for heavy-duty AGV intelligent transportation and applicable to railway freight car bogie frames with cross bars.

[0015] A railway freight car bogie frame support bracket is disclosed, suitable for heavy-duty AGV intelligent transportation and applicable to railway freight car bogie frames with crossbars. Its components include positioning supports, workpiece supports, baffles, material racks, material plates, hexagonal head bolts, positioning and fixing blocks, rubber buffer pads, and anti-slip pads.

[0016] like Figure 1 , Figure 2 As shown, during operation, the heavy-duty AGV arrives at the placement area, enters from the hollow bottom of the material rack 4, and stops directly below it. After aligning with the positioning and fixing block 7, the heavy-duty AGV uses its own lifting device to lift the entire support frame, causing the anti-slip pad 9 of the material rack 4 to leave the ground. The heavy-duty AGV then travels along a predetermined path while supporting the entire support frame.

[0017] The AGV travels to the work area and stops. The robotic arm lowers the frame into the workpiece support block 2 to complete the lifting. The workpiece support block 2 and the positioning support 1 share the load. The bolster of the frame is in contact with the rubber buffer pad 8. Limiting plates are located on both sides of the rubber buffer pad 8 to limit the horizontal displacement of the frame. After completing the load-bearing, the heavy-duty AGV continues to travel along the predetermined path, supported by the frame's bracket.

[0018] During operation, the baffle 3 fixed on the material plate 5 serves as a safety protection component to prevent the frame from sliding directly to the ground due to inertia or other reasons.

[0019] After driving back to the placement area, the heavy-duty AGV can lower the support frame of the load-bearing structure to the ground, and the anti-slip pad 9 of the material rack 4 will contact the ground. The heavy-duty AGV will then drive away from the hollow position at the bottom of the material rack 4 and continue the cycle.

[0020] This embodiment is merely an illustrative description of the present patent and does not limit its scope of protection. Those skilled in the art can make modifications to it, and as long as they do not change the spirit and essence of the present patent, they are considered equivalent substitutions to the present patent and are therefore within the scope of protection of the present patent.
