Abstract
Description
Technical Field
[0001] This application relates to the technical field of installation tooling, and specifically relates to a stacking device for a bulldozer mainframe. Background Art
[0002] The statements in this part only provide background technical information related to this application, and do not necessarily constitute prior art.
[0003] In the mass production of bulldozer mainframes, after the mainframes of bulldozers are produced and stored in a warehouse, if they are laid flat in the warehouse, a large amount of space is required. Therefore, a stacking method is adopted for storage. However, if directly stacked, since there are crossbeams in the front of the bulldozer mainframe and a rear axle housing at the rear, the crossbeams protrude below the bulldozer mainframe, and the stacking process is not stable. The bottom of the rear axle housing is arc-shaped, and during stacking, it is also not stable and prone to tipping over, causing safety accidents. Therefore, a stacking device for a bulldozer mainframe is needed, which can stack bulldozer mainframes safely and stably together. Summary of the Utility Model
[0004] To solve the above problems, this application proposes a stacking device for a bulldozer mainframe.
[0005] The purpose of this application is to provide a stacking device for a bulldozer mainframe. The crossbeam of the bulldozer mainframe is supported by the first bracket to keep the top of the bulldozer mainframe flat. Then, the second bracket is fixedly connected above the rear axle housing of the bulldozer mainframe. The V-shaped plate of the second bracket can adapt to the curvature of the rear axle housing stacked above, facilitating the stacking of the upper bulldozer mainframe. In this way, the first bracket and the second bracket can prevent the bulldozer mainframe from tipping over during the stacking process.
[0006] To achieve the above purpose, this application adopts the following technical solutions:
[0007] A stacking device for a bulldozer mainframe includes: a first bracket and a second bracket. The first bracket supports the front crossbeam of the bulldozer mainframe, and the second bracket supports the rear axle housing of the bulldozer mainframe. The first bracket is a cuboid frame, and a limiting block is provided on the side of the cuboid frame close to the crossbeam. The limiting block can prevent the crossbeam from moving on the cuboid frame. The second bracket includes: a limiting plate, a support plate, a mounting plate, and a rib plate. The support plate is a V-shaped plate, a limiting plate is provided on one side of the V-shaped plate, and the limiting plate is located above the V-shaped plate. The side of the support plate away from the limiting plate is fixedly connected to the mounting plate, the mounting plate is located below the support plate, and through holes are provided on the mounting plate. The rib plate is located at the connection between the support plate and the mounting plate.
[0008] As a further preference, there are two groups of limit blocks on the first bracket. The two groups of limit blocks are respectively located at the upper and lower ends of the rectangular frame. Each group has two limit blocks. The two limit blocks in one group are axisymmetric about the midline of the rectangular frame, and the distance between the two limit blocks in one group is greater than or equal to the width of the cross beam.
[0009] As a further preference, there are two rib plates. The two rib plates are axisymmetric about the midline of the support plate, and the rib plates are perpendicular to the support plate and the mounting plate respectively.
[0010] As a further preference, the limit plate is strip-shaped. The limit plate is located in the middle of the support plate, and the limit plate connects the two ends of the V-shaped plate.
[0011] As a further preference, the mounting plate is a Y-shaped plate. The width of the Y-shaped plate is greater than the width of the V-shaped plate, and the upper part of the Y-shaped plate is fixedly connected to the lower part of the V-shaped plate by welding.
[0012] As a further preference, the position of the through hole corresponds to the position of the mounting hole on the main frame of the bulldozer.
[0013] Compared with the prior art, the beneficial effects of the present application are as follows:
[0014] 1. In the present application, the cross beam is supported by the first bracket to keep the top of the main frame of the bulldozer flat. Then, the second bracket is fixedly connected above the rear axle housing of the main frame of the bulldozer. The V-shaped plate of the second bracket can adapt to the curvature of the rear axle housing stacked above, which is convenient for stacking the main frame of the bulldozer above. In this way, the first bracket and the second bracket can prevent the main frame of the bulldozer from tipping over during the stacking process.
[0015] 2. In the present application, the limit blocks of the first bracket can prevent the cross beam from shaking during the support process. The limit plate of the second bracket can prevent the rear axle housing behind the main frame from swinging left and right, and connect the two ends of the V-shaped plate, playing a certain strengthening role.

[0022] The present application will be further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1
[0023] A stacking device for a bulldozer main frame, as Figures 1 - 5 shown, includes: a first support 4 and a second support 5. The first support 4 supports the front cross beam 2 of the bulldozer main frame 1, and the second support 5 supports the rear axle housing 3 of the bulldozer main frame 1. The first support 4 is a cuboid frame 7. A limit block 8 is arranged on one side of the cuboid frame 7 close to the cross beam 2. The limit block 8 can prevent the cross beam 2 from moving on the cuboid frame 7. The second support 5 includes: a limit plate 11, a support plate 9, a mounting plate 10, and a rib plate 13. The support plate 9 is a V-shaped plate. A limit plate 11 is arranged on one side of the V-shaped plate. The limit plate 11 is located above the V-shaped plate. The side of the support plate 9 away from the limit plate 11 is fixedly connected to the mounting plate 10. The mounting plate 10 is located below the support plate 9. Through holes 12 are arranged on the mounting plate 10. The rib plate 13 is located at the connection between the support plate 9 and the mounting plate 10, and the rib plate 13 supports the support plate 9 and the mounting plate 10.
[0024] As Figure 2 shown, there are two groups of limit blocks 8 on the first support 4. The two groups of limit blocks 8 are respectively located at the upper and lower ends of the cuboid frame 7. The upper limit block 8 corresponds to the upper bulldozer main frame 1, and the lower limit block 8 corresponds to the lower bulldozer main frame 1. Each group of limit blocks 8 has two. The distance between the two limit blocks 8 in a group is symmetric about the midline of the cuboid frame 7, and the distance between the two limit blocks 8 in a group is greater than or equal to the width of the cross beam 2. In this way, the two sides of the cross beam 2 are restricted by the limit blocks 8 to prevent the cross beam 2 from slipping off the cuboid frame 7.
[0025] As Figure 4 shown, there are two rib plates 13. The two rib plates 13 are symmetric about the midline of the support plate 9. The rib plates 13 are respectively perpendicular to the support plate 9 and the mounting plate 10. The connection strength between the support plate 9 and the mounting plate 10 is enhanced by the two rib plates 13, and the support strength of the support plate 9 is improved.
[0026] As Figure 3As shown, the limiting plate 11 is strip-shaped. The limiting plate 11 is located in the middle of the support plate 9. The limiting plate 11 is connected to both ends of the V-shaped plate. The limiting plate 11 prevents the main frame 1 of the bulldozer from swinging left and right and plays a certain strengthening role for the V-shaped plate.
[0027] As Figure 4 shown, the mounting plate 10 is a Y-shaped plate. The width of the Y-shaped plate is greater than the width of the V-shaped plate. The upper part of the Y-shaped plate is fixedly connected to the lower part of the V-shaped plate by welding, so that the mounting plate 10 can be tightly connected to the support plate 9 and bear the pressure on the support plate 9 to the greatest extent.
[0028] As Figure 1 shown, the position of the through hole 12 corresponds to the position of the mounting hole 6 on the main frame 1 of the bulldozer, which facilitates the detachable connection of the through hole 12 and the main frame 1 of the bulldozer by bolts, so that the mounting plate 10 can be fixed on the main frame 1 of the bulldozer below.
[0029] As Figure 5 shown, the thickness of the mounting plate 10 is equal to the thickness of the support plate 9, which is convenient for assembly.
[0030] In the technical solution of the present application, first, the cross beam 2 of the main frame 1 of the bottommost bulldozer is supported by the first bracket 4, so as to ensure that the upper part of the main frame 1 of the bulldozer is in a horizontal state. Then, the two second brackets 5 are respectively installed on both sides of the top of the main frame 1 of the bulldozer at positions corresponding to the rear axle housing 3. The two second brackets 5 are axisymmetric with respect to the midline of the main frame 1 of the bulldozer. The through holes 12 of the second brackets 5 correspond to the mounting holes 6 of the main frame 1 of the bulldozer and are fixed by bolts, so that the second brackets 5 can be fixed on the main frame 1 of the bulldozer. Then, one end of the next first bracket 4 is placed above the cross beam 2 of the main frame 1 of the bulldozer, and the limiting block 8 below the first bracket 4 is fixed on the cross beam 2 below. After arranging the two support frames like this, another main frame 1 of the bulldozer can be hoisted above by a crane. Adjust the position of the crane, align the cross beam 2 of the upper main frame 1 of the bulldozer with the first bracket 4, and then align the position of the rear axle housing 3 of the upper main frame 1 of the bulldozer with the second bracket 5. Then, after lowering, the stacking can be completed. Then, repeat the installation of the first bracket 4 and the second bracket 5, so that the upper main frame 1 of the bulldozer can be continuously stacked on the lower main frame 1 of the bulldozer. The V-shaped plate can adapt to the radian of the rear axle housing 3, and the placement is more stable. The limiting plate 11 can prevent the main frame 1 of the bulldozer from shaking, improve the stability of the placement, and prevent the main frame 1 of the bulldozer from tipping over.
[0031] Although the specific implementation manners of the present application have been described above in conjunction with the accompanying drawings, they do not limit the protection scope of the present application. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present application are still within the protection scope of the present application.
