DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] With reference to Figures 1 to 3 , the present application provides an embodiment: a modularized and quickly replaceable bogie frame, comprising a bearing plate 1, a plurality of supports 2 are fixedly connected to the top end of the bearing plate 1, a plurality of damping columns one 3 are fixedly connected to the inner side of the far side of the plurality of supports 2 respectively, the damping column one 3 can convert mechanical energy into heat energy by the shear deformation of the internal damping material, so as to consume vibration energy. A plurality of concave damping pads 5 are slidingly connected to the inner side of the far side of the plurality of supports 2 respectively, when subjected to external impact force, the concave damping pad 5 can slide in a specific direction in the support 2, and absorb impact energy through its elastic deformation, a plurality of limit blocks one 6 are fixedly connected to the inner side of the far side of the plurality of supports 2 respectively, which mainly provides an installation fulcrum for the connecting shaft one 7 and limits the rotation range of the connecting shaft one 7, so as to ensure that the damping rod 8 swings within a reasonable angle range and prevent the structure from being damaged due to excessive swinging.

[0025] The inner side of the two limiting blocks 6 near each other is rotatably connected with a connecting shaft 7, the connecting shaft 7 is used as a connecting pivot between the damping rod 8 and the limiting block 6, and can flexibly rotate in the limiting block 6, the outer side of the two connecting shafts 7 near each other is fixedly connected with the damping rod 8, when subjected to vibration or impact, the damping rod 8 swings under the driving of the connecting shaft 7, the hydraulic damping device consumes the swing energy through the flow damping of oil, and effectively inhibits the transmission of vibration. The inner side of the two damping rods 8 near each other is fixedly connected with a connecting shaft 9, the connecting shaft 9 connects the damping rod 8, the limiting block 10 and the convex damping pad 11 together, so that the swing of the damping rod 8 can be smoothly transmitted to the convex damping pad 11, the force transmission of the whole damping system is smooth, the cooperation of the components is ensured, and the damping effect is jointly played.

[0026] The upper and lower ends of the two connecting shafts 9 are rotatably connected with the limiting block 10, so that the connecting shaft 9 can remain stable when subjected to force, the structure failure caused by excessive rotation is prevented, and meanwhile, the movement of the convex damping pad 11 is guided and limited. The end of the plurality of limiting blocks 10 near each other is fixedly connected with the convex damping pad 11, when subjected to external impact force, the convex damping pad 11 elastically deforms under the driving of the damping rod 8 and the connecting shaft 9, and together with the concave damping pad 5, impact energy is absorbed and dispersed, the buffering performance of the whole damping system is further enhanced, the side away from each other of the plurality of convex damping pads 11 is fixedly connected with the damping column 12, and the damping column 12 is fixedly connected on the convex damping pad 11, so that when the convex damping pad 11 is impacted, the damping column 12 can consume energy through its damping property, and at the same time, the damping column 12 can provide a reverse supporting force for the convex damping pad 11, slow down the deformation speed of the convex damping pad 11, and further improve the damping effect.

[0027] The side away from each other of the plurality of damping columns 12 is fixedly connected with the protective pad 14, the protective pad 14 is used as the outermost protective structure of the bogie frame, directly contacts with the external environment, can effectively resist stone impact, rain erosion, sand abrasion and other external damages, and protects the internal damping structure and other important components. Meanwhile, when impacted, the elastic deformation of the protective pad 14 can also absorb part of the energy, and provide additional buffering protection for the whole frame. The inside of the bearing plate 1 is fixedly connected with a lifting assembly for lifting.

[0028] Referring to Figures 2 to 4 , the lifting assembly comprises two slide columns 15, which are used as the guiding and supporting components of the transverse movement of the lifting ring 18, and realize the functions of the extension or retraction of the lifting ring 18 through the sliding in the inner wall of the bearing plate 1. The outer sides of the two ends of the two slide columns 15 are slidably connected to the inner walls on the two sides of the bearing plate 1, and the outer sides of the sides away from each other of the two slide columns 15 are rotatably connected with the right connecting column 16, when the lifting ring 18 is pulled, the connecting column 16 can rotate on the slide column 15, and at the same time, moves along with the sliding of the slide column 15, so as to drive the lifting ring 18 to reach the specified position.

[0029] The far side of the two connecting columns 16 is respectively fixedly connected with the right lifting ring 18. The operator applies a pulling force through the lifting ring 18, the lifting ring 18 transmits the force to the connecting column 16, and then the force is transmitted to the load-bearing plate 1 through the connecting column 16 and the slide column 15, and finally the bogie frame is lifted. The top end of the two connecting columns 16 is respectively internally threadedly connected with a limiting nut two 19. When the slide column 15 drives the connecting column 16 and the lifting ring 18 to extend to a suitable position, the limiting nut two 19 can be screwed with the threaded hole in the top end of the load-bearing plate 1, so as to fix the connecting column 16 and the slide column 15, and prevent them from sliding during lifting. The two sides of the load-bearing plate 1 are respectively internally threadedly connected with a limiting nut one 17. When the slide column 15 slides to a specified position, the limiting nut one 17 can be matched with the threads on the slide column 15 to fix the slide column 15.

[0030] Referring to Figures 1 to 3The outer threads of the two limiting nuts two 19 are connected to the inner top of the bearing plate 1, and the limiting nuts two 19 are tightened to firmly lock the connecting columns 16 on the bearing plate 1, preventing the lifting rings 18 from accidentally sliding during lifting operations. The similar sides of the two limiting nuts one 17 are externally threaded on the outside of the two sliding columns 15. When the sliding columns 15 move with the lifting rings 18, the limiting nuts one 17 can fix the approximate position of the sliding columns 15 in advance, providing a basis for the precise locking of the limiting nuts two 19. The outer sides of the two connecting columns 16 are slidingly connected to the inner walls of the bearing plate 1 on both sides. When lifting is required, the operator pulls the lifting ring 18, and the connecting column 16 slides in the inner wall of the bearing plate 1, realizing the extension of the lifting ring 18. After lifting is completed, the lifting ring 18 is pushed in the opposite direction, and the connecting column 16 drives the lifting ring 18 to retract. The outer sides of the two lifting rings 18 are slidingly connected to the inner walls of the bearing plate 1 on both sides. When the connecting column 16 slides, the lifting ring 18 moves synchronously along the guide groove in the inner wall of the bearing plate 1. During lifting, the lifting ring 18, as a direct force receiving component, transmits the lifting force to the bearing plate 1 through the connecting column 16 and the sliding column 15. The outer sides of the multiple damping columns one 3 are each sleeved with a spring one 4. When the impact force decreases, the spring one 4 pushes the concave damping pad 5 back to its original position by its own elastic restoring force, and cooperates with the damping column one 3 to continuously exert the damping effect. The spring one 4 is sleeved outside the damping column one 3, providing elastic support for the concave damping pad 5 and limiting its movement amplitude to prevent structural failure due to excessive displacement. The outer sides of the multiple damping columns two 12 are each sleeved with a spring two 13. The spring two 13 is sleeved outside the damping column two 12, together with the damping column two 12, to form a two-stage damping structure, further weakening the vibration and impact force transmitted to the bogie frame. The similar sides of the multiple limiting blocks two 10 are fixedly connected to the two sides of the convex damping pad 11. When the convex damping pad 11 is elastically deformed by an impact force, the limiting block two 10 cooperates with the connecting shaft two 9 and the damping rod 8 to orderly transmit the impact force, ensuring the stability of the entire damping system. The similar sides of the multiple protective pads 14 are slidingly connected to the far sides of the multiple supports 2. They absorb part of the impact force through their elastic deformation, and reduce direct impact on the supports 2. The far sides of the multiple concave damping pads 5 are slidingly connected to the similar sides of the multiple convex damping pads 11. The concave damping pad 5 and the convex damping pad 11 are mutually extruded and slid, absorbing and dispersing impact energy through their elastic deformation and relative displacement, and cooperating with the damping column one 3, the spring one 4, the damping column two 12, and the spring two 13 to achieve multi-stage damping effect. The far sides of the multiple damping columns one 3 are fixedly connected to the similar sides of the multiple concave damping pads 5, and the outer sides of the multiple convex damping pads 11 are slidingly connected to the interiors of the multiple supports 2. When the convex damping pad 11 is impacted, it slides in the sliding groove inside the support 2, disperses the impact force to the support 2 through interaction with the inner wall of the support 2, and elastically deforms to absorb energy.The bottom ends of the plurality of supports 2 are respectively fixedly connected with a plurality of support columns 20, the main function of the support columns 20 is to further disperse the load transmitted by the supports 2 to the connecting frames 21 below, and meanwhile enhance the vertical support strength of the whole bogie frame. The bottom ends of the two support columns 20 are respectively fixedly connected with the connecting frames 21, which play the role of connecting the upper and lower parts, and uniformly distribute the load transmitted by the support columns 20 to the rotating wheels 23. The proximal sides of the two connecting frames 21 are rotationally connected with rotating shafts 22, the rotating wheels 23 drive the rotating shafts 22 to rotate through the friction force generated by the contact with the track, the rotating shafts 22 further transmit the rotation to the connecting frames 21 and the whole bogie frame, and the movement of the vehicle is realized. The outer ends of the two rotating shafts 22 are respectively fixedly connected with the rotating wheels 23.

[0031] Working principle: when the bogie frame is impacted by external impact, the damping column II 12 is driven to move by the force of the protective pad 14, the spring II 13 is compressed to generate initial buffering, at the same time, the convex damping pad 11 is rotationally connected with the damping rod 8 through the connecting shaft II 9, and the impact force is transmitted to the damping rod 8, the damping rod 8 further drives the connecting shaft I 7 and the limiting block I 6 to move, so that the concave damping pad 5 slides in the support 2, the spring I 4 outside the damping column I 3 is compressed to generate secondary damping, and the sliding cooperation of the concave damping pad 5 and the convex damping pad 11 further disperses the impact force, the multiple damping columns and spring structures work cooperatively to effectively weaken the vibration energy, thereby realizing the effects of efficiently absorbing external impact force, reducing vibration transmission and enhancing protection performance, providing reliable protection for the bogie frame and its internal components, prolonging the service life of the bogie frame, and ensuring the stable operation of the bogie frame under complex working conditions.

[0032] When the bogie frame needs to be lifted, the lifting ring 18 is pulled to drive the connecting column 16 to move, the connecting column 16 slides in the inner walls on both sides of the bearing plate 1 while driving the slide column 15 to slide horizontally in the inner wall of the bearing plate 1, so that the lifting ring 18 extends to a suitable position, at this time, the limiting nut II 19 is fixedly matched with the top end of the bearing plate 1, and the limiting nut I 17 is tightly connected with the slide column 15, thereby fixing the position of the lifting ring 18; after the lifting operation is completed, the lifting ring 18 is pushed in the reverse direction to drive the connecting column 16 and the slide column 15 to slide in the reverse direction, so that the lifting ring 18 is hidden in the inner wall of the bearing plate 1, thereby realizing the effects of conveniently extending the lifting assembly for use and quickly retracting the lifting assembly for storage, which not only meets the needs of lifting and carrying the bogie frame, but also reduces the occupied space when the bogie frame is idle, improves the operation convenience and space utilization rate, and optimizes the use and storage experience of the bogie frame.

[0033] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
