Description

Technical Field

[0001] The present invention relates to the technical field related to railway freight cars, and in particular to a buffer locking device for a fully-open top cover of a railway vehicle. Background Art

[0002] Railway freight cars are vehicles specifically designed for transporting freight. They are designed to carry a variety of cargo types, including bulk goods, containers, liquids, and gases. Railway freight cars play a vital role in logistics and supply chain management, enabling efficient and economical long-distance transportation. Existing fully open roofs on railway vehicles often use pneumatic cylinders as their power source. During the opening and closing process, the cylinder piston rod's movement speed is unstable due to the shifting center of gravity of the roof, causing the roof to experience significant impact during closing, potentially damaging the structure. To prevent the roof from accidentally opening after closing, a locking device is typically installed on the roof for protection.

[0003] Currently, a common method for reducing impact forces on the roof is to install a rubber cushion between the roof and the vehicle body. However, this cushion has poor reliability and is prone to aging and breakage, requiring frequent replacement. Furthermore, the rubber cushion has a short elastic travel, resulting in poor cushioning effect on the roof. This can cause the roof to rebound during opening and closing, hindering its use. Therefore, a cushioning locking device for fully open roofs on railway vehicles is urgently needed to address this issue. Summary of the Invention

[0004] The object of the present invention is to provide a buffer locking device for a fully open roof of a railway vehicle to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A buffer locking device for a fully open roof of a railway vehicle comprises a roof panel, a groove body is provided at the bottom of the roof panel, a buffer mechanism and a locking mechanism are movably installed inside the groove body, the locking mechanism comprises a matching clamping block and a clamping member, the buffer mechanism comprises an arc-shaped push rod and a mechanical arm, the clamping block and the clamping member are respectively located on both sides of the mechanical arm, the arc-shaped push rod is located on one side of the roof panel, and the arc-shaped push rod is used to adjust the use angle of the mechanical arm.

[0006] By adopting the above-mentioned invention content, by arranging a buffer mechanism on the top plate, an effective buffering effect can be achieved on the top plate during the closing process of the top plate. At the same time, during the closing process of the top plate, the arc-shaped push rod can push the mechanical arm to move so that the clamping block and the clamping part in the locking mechanism are fitted and fixed. While providing a certain buffer to the top plate, the top plate is locked, thereby reducing the probability of the top plate rebounding.

[0007] Preferably, the buffer mechanism also includes a fixing rod, which is opened on the surface of the top plate, and the arc-shaped push rod is movably installed on the surface of the fixing rod. The port of the arc-shaped push rod is fixedly installed with a protrusion, and the bottom surface of the robotic arm is opened with a groove, and the notch size of the groove is adapted to the port of the arc-shaped push rod.

[0009] Preferably, one end of the robotic arm is clamped in the interior of the trough body, and a third movable shaft is movably installed at the connecting end of the robotic arm and the trough body.

[0013] Preferably, the connecting end of the connecting block and the robotic arm is movably connected with a second movable axis.

[0014] By adopting the above invention, the second movable shaft is used to assist in adjusting the angle of the connection between the connecting block and the robotic arm, so that the robotic arm can push the connecting block to achieve a horizontal angle connection state.

[0015] Preferably, a first movable shaft is movably installed at the connection between the connecting member and the trough body.

[0022] By adopting the above invention content, during the clamping process, the clamping block will be clamped into the groove inside the clamping part. When the locking operation is released, the arc-shaped push rod will push the robotic arm again so that the clamping block will slide out of the clamping part, making it easier for the top plate to close.

[0023] Preferably, a plurality of the trough bodies are provided, and the number of the buffer mechanisms and the locking mechanisms is adapted to the number of the trough bodies.

[0024] By adopting the above invention, multiple buffer mechanisms and locking mechanisms can greatly improve the buffering efficiency and locking performance of the top plate, so that the top plate remains stable and the probability of damage and rebound after collision is greatly reduced.

[0025] In the above invention, the present invention provides a buffer locking device for a fully open roof of a railway vehicle, which has the following beneficial effects: 1.
