Description

Technical Field

[0001] This utility model relates to the field of bogie technology, and in particular to a bogie stacking structure. Background Technology

[0002] Bogie stacking refers to the method of storing railway vehicle bogies in multiple layers using specialized structures or equipment. This method aims to improve space utilization, optimize storage and turnover efficiency, and ensure the stability and safety of the bogies in the stacked state. Its core is to transform the bogies from flat, dispersed storage to three-dimensional centralized storage by designing a suitable stacking structure. It is widely used in vehicle production workshops, maintenance bases, warehousing centers and other scenarios.

[0003] When bogies of different gauges need to be stored, rails of the corresponding gauge need to be built, which consumes a lot of manpower and resources. Moreover, they can only be stored individually, resulting in low space utilization. During long-term storage, uneven rails and surface impurities may cause wear on the wheel treads, reducing their service life.

[0004] The existing patent (publication number: CN222592200U) discloses a bogie stacking structure. This utility model solves the problem that bogies can only be stored individually on the track, resulting in low space utilization. The bogie stacking device provides a new way of storing bogies, which allows bogies to be safely and efficiently stacked on flat ground, significantly improving the utilization efficiency of the work site. The overall tooling design takes into account the diversity of track gauge and wheelset types, and is also applicable when track gauge and wheelset models change.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, some existing structures for stacking bogies are inconvenient to move using external handling equipment, making bogie stacking rather inconvenient and hindering multi-layer stacking, resulting in low space utilization.

[0006] To address this, a bogie stacking structure is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] A bogie stacking structure includes two stacking support plates 1. Support rails 5 are provided on both sides of the inner wall of the stacking support plate 1. Connecting mechanisms 6 are provided on the front and rear sides of both sides of the stacking support plate 1. Limiting mechanisms 8 are provided on the front and rear sides of the top of the support rails 5. The surface of the support rails 5 is in movable contact with the inner wall of the stacking support plate 1.

[0031] The connecting mechanism 6 includes two reinforcing blocks 601, a connecting hook 602, and a lifting block 603. The bottom of the reinforcing block 601 is fixedly connected to the top of the lifting block 603. The side of the reinforcing block 601 near the stacking support plate 1 is fixedly connected to a stacking support plate 1. The side of the lifting block 603 near the stacking support plate 1 is fixedly connected to the stacking support plate 1.

[0032] In this embodiment: two stacking support plates 1 serve as the load-bearing base, made of low-alloy high-strength structural steel. The support rails 5 on both sides of their inner walls are also made of the same material, capable of bearing the weight of the bogie and in movable contact with the inner wall of the stacking support plate 1. The reinforcing block 601, connecting hook 602, and lifting block 603 in the connecting mechanism 6 on both sides of the stacking support plate 1, as well as the limiting block 805 in the limiting mechanism 8 at the top of the support rail 5, are all made of low-alloy high-strength structural steel. By rotating the track gauge adjusting screws 7 on both sides of the stacking support plate 1, the distance between the two support rails 5 can be adjusted to match the bogie wheel track by rotating within the rotating block 12 via the second rotating shaft 11. After placing the bogie wheel tread on the surface of the support rail 5, rotating the limiting adjusting screw 801 causes the triangular limiting block 805 to move via the first rotating shaft 803 within the rotating frame 804, contacting the wheel tread and restricting the movement of the bogie. The bottom stacking support plate 1 has four evenly distributed support blocks 2 at its bottom, providing stable support. The bottom support legs 3 and bottom insert blocks 4 of the top stacking support plate 1 are made of low-alloy high-strength structural steel. The insert blocks 4 are inserted into the limiting holes 9 of the bottom stacking support plate 1 to achieve positioning and stacking. The support legs 3 are reinforced with braces 10 to enhance the support strength. During transportation, the stacking support plate 1 can be moved by contact between the forklift and the lifting block 603 or by connection between the hoisting equipment and the connecting hook 602. Furthermore, the stability of multi-layer stacking can be improved by attaching external ropes to the connecting hook 602. Multi-layer stacking achieves a high space utilization rate. The low-alloy high-strength structural steel ensures the strength and reliability of each component. This solves the problem that some existing structures for stacking bogies are inconvenient to move by external handling equipment, making it difficult to stack bogies and inconvenient to stack bogies in multiple layers, resulting in low space utilization.

[0033] Specifically, such as Figure 5As shown, the limiting mechanism 8 includes a limiting adjusting screw 801, a fixing block 802, a first rotating shaft 803, a rotating frame 804, and a limiting block 805. The limiting block 805 is slidably connected to the surface of the support rail 5. The bottom of the fixing block 802 is fixedly connected to the top of the support rail 5. The limiting adjusting screw 801 is threadedly connected to the inside of the fixing block 802. The side of the limiting adjusting screw 801 near the first rotating shaft 803 is fixedly connected to the first rotating shaft 803. The first rotating shaft 803 is rotatably connected to the inside of the rotating frame 804. The side of the rotating frame 804 near the limiting block 805 is fixedly connected to the limiting block 805.

[0034] Specifically, such as Figure 4 and Figure 6 As shown, both sides of the stacking support plate 1 are provided with a gauge adjustment screw 7. The gauge adjustment screw 7 is movably connected inside the stacking support plate 1 and threadedly connected inside the support rail 5.

[0036] In this embodiment, the limiting mechanism 8, through the cooperation of the limiting adjustment screw 801, the first rotating shaft 803, etc., makes the limiting block 805 precisely fit the bogie wheel tread, effectively restricting movement. The track gauge adjustment screw 7, combined with the second rotating shaft 11 and the rotating block 12, can flexibly adjust the spacing of the support rail 5 to adapt to bogies with different wheel gauges, thereby improving the structural versatility and fixing reliability.

[0037] Specifically, such as Figure 3 and Figure 7 As shown, limit holes 9 are provided at the four corners of the top of the stacking support plate 1, and support legs 3 are fixedly connected to the four corners of the bottom of the top stacking support plate 1. Insert blocks 4 are fixedly connected to the bottom of the support legs 3, and the insert blocks 4 are movably inserted into the bottom limit holes 9.

[0038] Specifically, such as Figure 4 As shown, a reinforcing brace 10 is fixedly connected to the surface of the support leg 3.

[0039] In this embodiment: the support legs 3 and the insert blocks 4 of the top stacking support plate 1 are inserted into the limiting holes 9 of the bottom stacking support plate 1 to achieve rapid positioning and stacking. The reinforcing support 10 enhances the support strength of the support legs 3, ensuring the structural stability during multi-layer stacking and improving stacking efficiency and safety.

[0040] Specifically, such as Figure 1 As shown, the bottom of the bottom stacking support plate 1 is fixedly connected with support blocks 2. There are four support blocks 2, which are evenly distributed on the bottom of the bottom stacking support plate 1.

[0041] Specifically, such as Figure 1 and Figure 3 As shown, the reinforcing block 601, connecting hook 602, lifting block 603, stacking support plate 1, support rail 5, limiting block 805, support leg 3, insert block 4, support block 2 and reinforcing support 10 are all made of low alloy high strength structural steel.

[0042] In this embodiment: four evenly distributed support blocks 2 at the bottom enhance the overall support stability. The reinforcing block 601, connecting hook 602, lifting block 603, stacking support plate 1, support rail 5, limiting block 805, support leg 3, insert block 4, support block 2 and reinforcing support 10 are all made of low alloy high strength structural steel to ensure load-bearing strength and durability, meet the high strength requirements of heavy object stacking, and extend the service life of the structure.

[0043] Working Principle: Two stacking support plates 1 serve as the load-bearing foundation, made of low-alloy high-strength structural steel to ensure the overall structural load-bearing strength. The support rails 5 on both sides of the inner wall of the stacking support plate 1 are also made of low-alloy high-strength structural steel, capable of bearing the weight of the bogie. The support rails 5 are in movable contact with the inner wall of the stacking support plate 1 for position adjustment. In the connecting mechanisms 6 on the front and rear sides of the stacking support plate 1, the reinforcing block 601, connecting hook 602, and lifting block 603 are all made of low-alloy high-strength structural steel, improving the stability of the connection. In the limiting mechanisms 8 on the front and rear sides of the top of the support rail 5, the limiting block 805 is made of low-alloy high-strength structural steel and is slidably connected to the surface of the support rail 5. The bottom of the fixing block 802 is fixedly connected to the top of the support rail 5. The limiting adjustment screw 801 is threadedly connected. Inside the fixed block 802, the side of the fixed block near the first rotating shaft 803 is fixedly connected to the first rotating shaft 803. The first rotating shaft 803 is rotatably connected inside the rotating frame 804. The side of the rotating frame 804 near the limiting block 805 is fixedly connected to the limiting block 805. The track gauge adjusting screws 7 on both sides of the stacking support plate 1 are movably connected inside the stacking support plate 1 and threadedly connected inside the support rails 5. The second rotating shaft 11, which is fixed to the surface of the track gauge adjusting screw 7, is rotatably connected inside the rotating block 12. The bottom of the rotating block 12 is fixed to the bottom of the inner wall of the stacking support plate 1. By rotating the track gauge adjusting screw 7, the rotation of the second rotating shaft 11 inside the rotating block 12 drives the two support rails 5 to adjust the distance on the inner wall of the stacking support plate 1 to match the wheel track of the stacked bogie. Then the bogie is moved to the wheel tread. Placed on the surface of the support rail 5, the limit adjusting screw 801 is rotated to make the first rotating shaft 803 rotate within the rotating frame 804, driving the triangular limit block 805 connected to the rotating frame 804 to move until the limit block 805 contacts the bogie wheel tread surface, restricting the bogie movement. The four support blocks 2 at the bottom of the bottom stacking support plate 1 are made of low-alloy high-strength structural steel, evenly distributed to stably support the whole. The support legs 3 at the four corners of the bottom of the top stacking support plate 1 are made of low-alloy high-strength structural steel, and the insert blocks 4 at their bottoms are also made of the same material. They can be movably inserted into the limit holes 9 at the four corners of the top of the bottom stacking support plate 1 to achieve the positioning and stacking of the top stacking support plate 1 and the bottom stacking support plate 1. The reinforcing braces 10 fixed on the surface of the support legs 3 are made of low-alloy high-strength structural steel, which enhances the support strength of the support legs 3. During transport, the stacking support plate 1 and the supporting bogie can be moved by contacting the inner wall of the lifting block 603 via an external forklift. The hoisting equipment connects to the connecting hook 602, allowing for rapid movement of the stacking support plate 1. This facilitates moving the top stacking support plate 1 to the top of the bottom stacking support plate 1 for stacking. Multiple top stacking support plates 1 can be stacked sequentially. To ensure the stability of multi-layer stacking, external ropes can be attached to the connecting hook 602 and connected to external force points, further enhancing stacking stability. Multi-layer stacking achieves high space utilization. The use of low-alloy high-strength structural steel ensures the strength and reliability of each component during load-bearing, connection, transport, and stacking processes. This solves the problem that some existing bogie stacking structures are inconvenient to move using external handling equipment.Stacking bogies is inconvenient, and multi-layer stacking is not feasible, resulting in low space utilization.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
