[0002] The high-speed rail wheel set is large in volume and mass, and needs to be limited and fixed by a special packaging rack during long-distance transportation.

[0003] The traditional high-speed rail wheel set packaging rack is of a frame structure, including a rectangular frame structure fixed relatively on the outside and an arc-shaped limiting structure arranged inside the frame structure. The high-speed rail wheel set is transferred to a predetermined position by a hoisting device such as a traveling crane to realize the packaging and limitation of the high-speed rail wheel set.

[0004] However, the traditional wheel set packaging rack is large in volume, and the transfer of the packaging rack and the hoisting process of the wheel set are both relatively cumbersome. Moreover, the traditional wheel set packaging rack has a complex structure and a low packaging density in the unit space volume, reducing the efficiency of wheel set packaging and subsequent transportation. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a wheel set packaging rack, which solves the problems mentioned in the background technique.

[0006] To achieve the above object, the utility model is realized through the following technical solutions:

A contact pad is arranged on one side of the fixing frame, and the wheel set is in contact with and abuts against the contact pad. A support rod is fixedly connected between the two support frames, and a flexible belt is sleeved between the wheel set shaft and the support rod. Both ends of the flexible belt are respectively provided with a matching frame and a corresponding frame.

[0008] To facilitate the installation process of the flexible belt, two symmetrically arranged buckles are fixedly connected to one side of the matching frame, and two symmetrically arranged clamping grooves are formed inside the corresponding frame, and the buckles are matched with the clamping grooves.

[0009] To strengthen the locking effect of the flexible belt during the installation process, two symmetrically arranged limiting rollers are rotatably connected inside both the matching frame and the corresponding frame, and the flexible belt is arranged between the two limiting rollers on the same side.

[0010] In order to tighten the flexible belt during the installation process and avoid the problem of reset loosening, it is proposed that the rotating shaft of the limiting roller is fixedly connected with a limiting gear, and the two limiting gears on the same side are meshed with each other.

[0011] In order to realize the convenient positioning and fixing process of the flexible belt during the installation process, it is proposed that both ends of the flexible belt are fixedly connected with connecting belts. The two connecting belts are symmetrically arranged about the center. Rack teeth are provided on the opposite side walls of the connecting belts. A connecting gear is rotatably connected in the corresponding frame. The connecting gear is meshed with the two connecting belts.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0018] As Figure 1As shown in the figure, the present utility model provides a wheel set packaging rack. In order to improve the packaging density effect of the wheel set 8 during the packaging process, it is proposed to include a plurality of support frames 1 distributed on both sides. One side of the support frame 1 is fixedly connected to a base 5, and one side of the support frame 1 is fixedly connected to a connecting frame 2. One side of the two connecting frames 2 is fixedly connected to an extension frame 3. Both the extension frame 3 and one side of the support frame 1 are fixedly connected to a fixing frame 6. A contact pad 7 is provided on one side of the fixing frame 6. The wheel set 8 is in contact with the contact pad 7. A support rod 4 is fixedly connected between the two support frames 1. A flexible belt 10 is sleeved between the wheel set shaft 9 and the support rod 4. Both ends of the flexible belt 10 are respectively provided with a matching frame 11 and a corresponding frame 12.

[0019] As Figure 1 、 Figure 3 shown in the figure, in order to facilitate the installation process of the flexible belt 10, it is proposed that two symmetrically arranged buckles 13 are fixedly connected to one side of the matching frame 11, and two symmetrically arranged card slots 14 are opened on the inner side of the corresponding frame 12. The buckle 13 is matched with the card slot 14.

[0020] As Figure 3 shown in the figure, in order to strengthen the locking effect of the flexible belt 10 during the installation process, it is proposed that two symmetrically arranged limiting rollers 17 are rotatably connected in both the matching frame 11 and the corresponding frame 12. The flexible belt 10 is arranged between the two limiting rollers 17 on the same side.

[0021] As Figure 3 shown in the figure, in order to realize the tightening of the flexible belt 10 during the installation process and avoid the problem of reset loosening, it is proposed that the rotating shaft of the limiting roller 17 is fixedly connected to a limiting gear 18, and the two limiting gears 18 on the same side are meshed.

[0022] As Figure 3 shown in the figure, in order to realize the convenient positioning and fixing process of the flexible belt during the installation process, it is proposed that both ends of the flexible belt 10 are fixedly connected to connecting belts 19. The two connecting belts 19 are centrosymmetrically arranged. Rack teeth are provided on the opposite side walls of the connecting belts 19. A connecting gear 15 is rotatably connected in the corresponding frame 12. The connecting gear 15 is meshed with the two connecting belts 19. A driving shaft 16 is fixedly connected to the rotating shaft of the connecting gear 15.

[0023] As Figures 1-3 shown in the figure, during use, first, the support frame 1 is connected and fixed through the two connecting frames 2 and the extension frame 3. At this time, the support frame 1, the connecting frame 2, and the extension frame 3 form a "Z"-shaped support contact. At the same time, the support frames 1 distributed on both sides can be connected through the connection of the support rod 4 to form the connection between the support frames 1 on the same layer. Subsequently, the wheel set 8 is arranged in the fixing frame 6 on the support frame 1 and the extension frame 3 for contact positioning, and contact protection is carried out in cooperation with the contact pad 7. At this time, as Figure 1As shown, the wheel set 8 on the extension frame 3 is placed out of alignment with the wheel sets on both sides, thereby increasing the packing density of the wheel set 8 during the packing and placement process. Subsequently, the upper support frame 1 is placed on the wheel set 8. At this time, the fixed frames 6 on the upper support frame 1 and the extension frame 3 form a corresponding structure with the fixed frames 6 on the lower support frame 1, cooperating to limit the wheel set 8 and ensure its stability during the packing and placement process. Subsequently, a flexible belt 10 is sleeved between the wheel set shaft 9 and the support rod 4 as Figure 2 shown, in which the flexible belt 10 during the installation process is as Figure 3 shown. First, the mating frame 11 and the corresponding frame 12 are fixedly connected by corresponding snap connections of the snap fasteners 13 and the card slots 14. At this time, the connecting belts 19 at both ends respectively extend to the connecting gears 15. Subsequently, the driving shaft 16 is rotated to drive the meshing of the connecting gears 15 with the connecting belts 19 on both sides, and the two ends of the traction flexible belt 10 are tightened by the meshing method. At this time, the connecting belt 19 is made of a hard metal material, thereby facilitating the tightening process of the flexible belt 10. During this process, the limiting rollers 17 on both sides rotate relative to each other under the meshing of the limiting gears 18 following the traction of the flexible belt 10. At this time, the flexible belt 10 is in contact-limited to prevent the problem of loosening of the flexible belt 10 due to its reverse movement.

[0024] Finally, the most important contribution of the present utility model compared with the prior art is that: through the "Z"-shaped placement structure composed of the extension frame 3 and the support frame 1, a greater packing density can be achieved during the packing and placement of the wheel set 8, that is, by staggering the adjacent two wheel sets 8, the problem of space occupation and waste of the packing rack can be reduced. At the same time, through the layered stacking method of the support frames, the placement and installation process of the packing rack can be facilitated, and the limiting of the wheel set 8 during the packing process can be facilitated.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
