[0002] When the existing 25-meter rails are transported by flat cars, bogies need to be used on two adjacent flat cars to fix the 25-meter rails and ensure the safety of rail transportation. Six-pivot bogies are widely used because of their simple structure and low cost. The existing six-pivot bogies are composed of a dead-center lower frame, a movable-center lower frame, two upper frames and four slides. The dead-center lower frame with the upper frame and the movable-center lower frame with the upper frame are respectively placed on two adjacent ordinary flat cars for use as a set. The dead-center lower frame and the movable-center lower frame are fixed to the flat car by spikes and wires. The disassembly and assembly process is cumbersome, the fixation is not stable enough, and the spikes and wires cannot be recycled, and the use cost is high.

[0003] The Chinese utility model patent with the authorization announcement number CN202703601U discloses a bogie for ordinary flat car transportation of 25-meter rails. The dead center plate lower frame and the movable center plate lower frame of the bogie are connected to the ordinary flat car through safety stoppers to avoid left and right sliding and movement. However, during long-term use, the gap between the dead center plate lower frame, the movable center plate lower frame and the safety stopper will gradually increase, causing the amount of sliding to increase, which may cause the rails to be overweight and concentrated in the vehicle during transportation, posing a serious safety hazard to railway transportation.

The bogie includes a dead-center lower frame 4, a movable-center lower frame 1 and a slide 5. The dead-center lower frame 4 and the movable-center lower frame 1 are respectively arranged on the two adjacent flat cars, and the slide 5 is arranged on the front and rear sides of the dead-center lower frame 4 and the front and rear sides of the movable-center lower frame 1. An upper frame 2 is set on the top of the dead-center lower frame 4 and the movable-center lower frame 1, and the bottoms of the dead-center lower frame 4 and the movable-center lower frame 1 are fixed to the flat car through a lower frame fixing frame 3.

[0045] like Figure 2 As shown, the lower frame 1 of the movable core plate includes a main frame 11 of the lower frame of the movable core plate, and a waist-shaped shaft hole 12 is opened in the middle of the main frame 11 of the lower frame of the movable core plate. Figure 3 As shown, a waist-shaped shaft sleeve 13 is detachably fixedly arranged on the inner wall of the waist-shaped shaft hole 12 by bolts.

[0046] like Figure 8 As shown, the dead center plate lower frame 4 includes a dead center plate lower frame main frame 41, and a circular shaft hole 42 is opened in the middle of the dead center plate lower frame main frame 41. Fig. 9 As shown, a circular shaft sleeve 43 is detachably fixedly arranged on the inner wall of the circular shaft hole 42 by means of bolts.

[0047] In this embodiment, oil grooves are provided on the inner walls of the waist-shaped sleeve 13 and the circular sleeve 43 to reduce the friction of the sleeves.

[0048] like Figure 7As shown, the lower frame fixing frame 3 includes a pull rod 32 and two fixing frame pillars 33. The fixing frame pillars 33 are inserted into the mounting hole 6 of the flat car. The mounting hole 6 is a through hole opened on the flat car. Bolt holes are opened near the upper and lower ends of the fixing frame pillars 33. The upper ends of the fixing frame pillars 33 are detachably fixedly connected to the lower frame 4 of the dead center plate or the lower frame 1 of the movable center plate through the fixing frame bolts 31. The lower ends of the fixing frame pillars 33 pass through the mounting hole 6. The lower ends of the two fixing frame pillars 33 are detachably fixedly connected to the pull rod 32. The pull rod 32 is arranged perpendicular to the length direction of the flat car. The lower ends of the fixing frame pillars 33 are detachably fixedly connected to the pull rod 32 through the fixing frame bolts 31. In addition, anti-loosening washers are arranged on the fixing frame bolts 31 to prevent the fixing frame bolts 31 from loosening.

[0049] In this embodiment, for the lower frame fixing frame 3 below the lower frame 1 of the movable core plate, the upper end of the fixing frame support 33 is connected to the end of the main frame connecting rod 111 of the lower frame main frame 11 of the movable core plate, and multiple main frame connecting rods 111 are arranged in parallel along the length direction of the lower frame 1 of the movable core plate, and a lower frame fixing frame 3 can be fixed on each main frame connecting rod 111, thereby ensuring the stability of the lower frame 1 of the movable core plate. For the lower frame 4 of the dead core plate, the position where the lower frame 4 of the dead core plate is connected to the lower frame fixing frame 3 is the same as that of the lower frame 1 of the movable core plate.

[0050] like Figure 4 As shown, the upper frame 2 includes an upper frame main frame 21, and a pin hole 22 is provided in the middle of the upper frame main frame 21. Figure 6 As shown, the upper frame pin 23 is detachably fixed in the pin hole 22 by a bolt, and the lower end of the upper frame pin 23 extends out of the pin hole 22, and is used to connect with the lower frame 4 of the dead center plate or the lower frame 1 of the movable center plate. The upper frame pin 23 can be inserted into the waist-shaped shaft hole 12 and the circular shaft hole 42, so that the upper frame pin 23 is connected to the lower frame 1 of the movable center plate in a sliding and rotating manner, or is connected to the lower frame 4 of the dead center plate in a rotating manner.

[0051] like Figure 5 As shown, a pad 26 or rubber is arranged on the top of the upper frame 2 to prevent the rail from colliding with and wearing the upper frame 2. Pull rings 25 are arranged at both ends of the upper frame 2, and the pull rings 25 are connected to the upper frame 2 through pull ring mounting columns 24.

[0052] like Fig.10 As shown, the slide 5 includes a slide main frame 51, which is arranged perpendicular to the length direction of the flat car. Slide 5 pillars are set at the bottom of the slide main frame 51 near the two ends. A limiting plate 53 is welded to the lower end of some mounting holes 6 of the flat car. The lower end of the slide 5 pillar is against the limiting plate 53 at the lower end of the mounting hole 6. The slide 5 pillar and the limiting plate 53 are detachably fixedly connected by bolts passing through the limiting plate 53.

[0053] A rubber layer 52 is disposed on the top of the slide main frame 51 , and an oil groove is provided on the top of the rubber layer 52 , which can reduce the wear of the rail on the rubber layer 52 and improve the flexibility of the rail when rotating.

[0054] The lower frame 4 of the dead center plate and the lower frame 1 of the movable center plate of the utility model are fixed on the flat car through the lower frame fixing frame 3, and the slide 5 is fixed on the flat car through the slide 5 pillar, which makes the fixation more firm, prevents sliding and movement, is easy to disassemble and assemble, and all structures can be recycled together. An oil groove is provided in the shaft sleeve, which makes the rotation and sliding more flexible and reduces the wear during use; the shaft sleeve can be replaced separately after long-term use and wear, which reduces the maintenance cost. The upper frame pin 23 can be detachably fixed in the upper frame 2, and the pin can be replaced separately after wear, without replacing the entire upper frame 2, which reduces the maintenance cost. The lower frame 1 of the movable center plate and the lower frame 4 of the dead center plate are connected to the lower frame fixing frame 3 by bolts. When the size of the flat car pillar slot changes, the corresponding lower frame fixing frame 3 can be replaced separately, which is easy to operate and has strong adaptability.

[0055] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
