Description

Technical Field

[0001] This utility model relates to the technical field of railway freight car parts, specifically a riveted upper plate for railway freight cars. Background Technology

[0002] The common connection methods for the upper center plate assembly of railway freight cars are mainly three structures: riveted, integral, and embedded. The riveted upper center plate assembly structure uses rivets to rivet the upper center plate to the traction beam. Its main features are simple structure and convenient maintenance, but there is a possibility that the rivets can be easily cut off.

[0003] When disassembling a riveted top plate, the rivets are usually cut off using external tools. If all four rivets are cut off directly, the top plate may fall off without any restraints, which can easily cause damage and increase the risk to the operator during disassembly.

[0004] Therefore, we propose a riveted top plate for railway freight cars to solve the problems mentioned above. Utility Model Content

A T-shaped locking block 20 is fixedly installed at the end of the threaded rod 19, and one side of the T-shaped locking block 20 is movably inserted into the inner cavity of the locking groove 4.

[0028] Specifically, with the cooperation of the limiting components, the two T-shaped blocks 20 are movably inserted into the inner cavity of the adjacent slots 4 on opposite sides, which can limit the upper plate body 2, preventing the upper plate body 2 from falling directly and being damaged after the rivets are cut without the limiting components, and at the same time improving the safety of the operator during disassembly.

[0029] On the other side of the T-shaped block 20, near the top and bottom, a limiting telescopic rod 21 is fixedly installed, and the other end of the limiting telescopic rod 21 is fixedly connected to the inner wall of the fixing groove 25.

[0030] Specifically, the T-shaped locking block 20 can be limited when it moves by setting the limit telescopic rod 21.

[0031] A T-shaped rod B22 is movably inserted through the front side of the rocker wheel 14 near the top. Several limiting blind holes B23 are opened at the middle position of the front side of the fixed box 3, and the rear end of the T-shaped rod B22 is movably inserted into the inner cavity of the limiting blind hole B23.

[0032] Specifically, by setting the T-shaped rod B22 to be inserted into the limiting blind hole B23, the rotation position of the rocker wheel 14 can be limited.

[0033] A spring B24 is movably sleeved on the outer periphery of the T-shaped rod B22 near the front end, and the front and rear ends of the spring B24 are fixedly connected to the rocker wheel 14 and one end of the T-shaped rod B22, respectively.

[0034] Specifically, the spring B24, which is movably sleeved on the outer periphery of the T-shaped rod B22, enables the T-shaped rod B22 to be stably inserted into the inner cavity of the limiting blind hole B23.

[0035] Example 2

[0036] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 3 and Figure 5 The protective components include cross grooves 8 located on the front side of the fixed box 3 near both sides and cross sliders 7 slidably connected in the inner cavity of adjacent cross grooves 8. Protective blocks 5 are fixedly installed on the front side of the cross sliders 7.

[0037] Specifically, by setting the protective block 5 on the front side of the rocker wheel 14, it can be protected.

[0038] Several anti-slip pads 6 are fixedly installed on the front side of the protective block 5, and all anti-slip pads 6 are made of rubber.

[0039] Specifically, several anti-slip pads 6 are set to facilitate the movement of the protective block 5.

[0040] A connecting ear 9 is fixedly installed on the other side of the protective block 5 near the middle position. A T-shaped rod A10 is movably inserted through the front side of the connecting ear 9. Limiting blind holes A12 are opened on the front side of the fixed box 3 near the top and bottom. The rear end of the T-shaped rod A10 is movably inserted into the inner cavity of the adjacent limiting blind hole A12. A spring A11 is movably sleeved on the outer periphery of the T-shaped rod A10 near the front end. The front and rear ends of the spring A11 are fixedly connected to the connecting ear 9 and the T-shaped rod A10, respectively.

[0041] Specifically, with the cooperation of spring A11, the T-shaped rod A10 can be stably inserted into the inner cavity of the adjacent limiting blind hole A12, which can limit the position of the protective block 5, prevent loosening, and improve the protective effect.

[0042] Working Principle: In use, when installing the upper center plate body 2, the protrusion of the upper center plate body 2 is inserted into the inner cavity of the circular groove. The upper center plate body 2 is then fixed with rivets. Pulling the T-shaped rod B22 forward moves its end away from the inner cavity of the adjacent limiting blind hole B23. Rotating the rocker wheel 14 causes the transmission rod 15 fixed on it to rotate. The driving bevel gear 17 rotates via the driving bevel gear 16 fixed on the transmission rod 15, which in turn rotates the threaded tube 18. The threaded rod 19, threaded into the inner cavity of the threaded tube 18, allows the T-shaped locking block 20 to be inserted into the inner cavity of the adjacent locking slot 4 under the limiting of the two adjacent limiting telescopic rods 21. Afterwards, the T-shaped rod B22 can be released, and the rotation position of the rocker wheel 14 is limited by the elastic force of the spring B24. Other limiting components... As described above, without further elaboration, with the cooperation of the limiting components, the two T-shaped blocks 20 are movably inserted into the inner cavities of adjacent slots 4 on opposite sides, which can limit the upper plate body 2, preventing the upper plate body 2 from falling directly and being damaged after the rivets are cut without limiting. At the same time, it improves the safety of the operator during disassembly. After limiting the upper plate body 2, the T-shaped rod A10 can be pulled forward to move the end of the T-shaped rod A10 away from the inner cavity of the limiting blind hole A12. Then, the protective block 5 can be slid downward to the front of the rocker wheel 14. Then, the T-shaped rod A10 can be released. Under the elastic force of the spring A11, the end of the T-shaped rod A10 can be inserted into the inner cavity of the adjacent limiting blind hole A12, which can limit the position of the protective block 5, prevent loosening, and improve the protective effect.
