Description

Technical Field

[0001] This utility model relates to the technical field of rail vehicles, specifically to an assembled top cover shipping fixture. Background Technology

[0002] The manufacturing process of rail vehicles involves multiple steps, from car body manufacturing and chassis manufacturing to internal assembly and testing. The car body is equivalent to the skeleton of a rail vehicle, mainly composed of five welded parts: the underframe, side walls, end walls, roof, and driver's cab. After the car body is manufactured, the final assembly process is carried out to assemble the car body.

[0003] According to the "A Car Roof Storage Fixture" provided in Chinese Patent Publication No. CN218576204U, the aforementioned document uses struts to support the roof. While this achieves the goal of fixing the roof, the roof's length and weight make it prone to deformation when supported only by a single fixed-point strut, thus affecting the overall quality of the fixture. Furthermore, since roofs of different specifications have varying longitudinal heights, using struts at fixed heights can lead to wasted fixture space. Therefore, we provide an assembled roof shipping fixture to address these issues. Utility Model Content

[0004] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes an assembled top cover shipping fixture, including a base, with columns installed at the four corners of the top of the base, and several support rods between two adjacent columns, with two limiting rods on the corresponding two support rods.

[0005] The support rod has a convex groove inside that corresponds to the limiting rod. The bottom of the limiting rod is integrally formed with a connecting block that fits the convex groove. The connecting block slides inside the convex groove. A locking bolt is provided below the connecting block. The locking bolt is threaded to the bottom end of the connecting block through the convex groove.

[0006] The column has a through groove on one side corresponding to the support rod, and the end of the support rod is provided with an adjusting bolt. The adjusting bolt is threadedly connected to the end of the support rod through the through groove.

[0007] Preferably, a sealing plate is provided on one side of the two adjacent columns. The sealing plate is rotatably connected to the outside of one of the columns. A concave block is integrally formed on the sealing side of the sealing plate. A fixing bolt corresponding to the concave block is integrally formed on the other column. The concave block can be snapped into the inside of the fixing bolt and fixed by a fixing nut.

[0008] Preferably, a connecting frame is fixedly provided between the two columns arranged along the length of the base.

[0009] The beneficial technical effects of this utility model are as follows: This shipping fixture, by setting support rods between the columns, with each support rod having two support points, can more stably support the top cover. Simultaneously, the sliding limiting rod design, once fixed, limits the position of the top cover. Furthermore, larger top covers can be limited by the columns or additional limiting rods, while narrower top covers can be limited by inner limiting rods. At the same time, the spacing between the support rods can be adjusted according to the longitudinal height of the top cover, thus avoiding wasted space. The closed plate design prevents the top cover from shifting along the limiting rod direction inside the fixture. In summary, while ensuring stable support for the top cover, it can also stably limit its position according to the longitudinal height and width of the top cover, making it highly practical.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] This utility model proposes an assembled top cover shipping fixture, including a base 1, with columns 2 installed at the four corners of the top of the base 1. A connecting frame 22 is fixedly installed between two columns 2 arranged along the length of the base 1. This design ensures the overall rigidity of the fixture. Several support rods 3 are provided between two columns 2 that are close to each other. By setting support rods 3 between the columns 2, and the support rods 3 having two support points, the top cover can be supported more stably. At the same time, the bottom of the support rods 3 can be designed as a straight line or a partial arc according to the top shape of the top cover, so as to fit with the top of the top cover. Two limiting rods 4 are provided on the two corresponding support rods 3.

[0018] The support rod 3 has a convex groove 32 inside that corresponds to the limiting rod 4. The bottom of the limiting rod 4 is integrally formed with a connecting block 41 that fits the convex groove 32. The connecting block 41 slides inside the convex groove 32. A locking bolt 411 is provided below the connecting block 41. The locking bolt 411 is threadedly connected to the bottom end of the connecting block 41 through the convex groove 32. Through the sliding limiting rod 4 design, the top cover is limited after it is fixed. Furthermore, a larger top cover can be limited by the column 2 or by adding a limiting rod 4, while a smaller top cover can be limited by the inner limiting rod 4.

[0019] The column 2 has a through groove 21 on one side corresponding to the support rod 3. The end of the support rod 3 is provided with an adjusting bolt 31. The adjusting bolt 31 is threadedly connected to the end of the support rod 3 through the through groove 21. The spacing between the support rods 3 is adjusted according to the longitudinal height of the top cover, thereby avoiding waste of space and preventing the top cover from moving inside the tooling.

[0020] Specifically, a sealing plate 23 is provided on one side of two adjacent columns 2. The sealing plate 23 is rotatably connected to the outside of one of the columns 2. A concave block 231 is integrally formed on the sealing side of the sealing plate 23. A fixing bolt 24 corresponding to the concave block 231 is integrally formed on the other column 2. The concave block 231 can be snapped into the inside of the fixing bolt 24 and fixed by the fixing nut 241. The design of the sealing plate 23 can prevent the top cover from moving along the direction of the limiting rod 4 inside the tooling.

[0021] Working principle: When using this fixture, the distance between the two corresponding limiting rods 4 can be adjusted according to the size of the top cover. At the same time, when it is necessary to load top covers of different widths into the fixture together, corresponding limiting rods 4 can be added so that multiple limiting rods 4 can limit two or more top covers at the same time. Then, tighten the locking bolts 411 at the bottom of the limiting rods 4 to fix the position of the limiting rods 4. Then, loosen the adjusting bolts 31 according to the longitudinal height of the top cover so that the support rod 3 can move longitudinally, thereby limiting the longitudinal movement space of the top cover and reducing the waste of fixture space. Finally, the entire top cover can be confined inside the fixture by closing the closing plate 23, and then it can be loaded into the transport vehicle for transfer.

[0022] Although the present invention has been described with reference to preferred embodiments, various modifications can be made to it and components can be replaced with equivalents without departing from the scope of the present invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
