Description

Technical Field

[0001] The utility model relates to the technical field of loader radiators, in particular to a radiator side frame and a loader radiator. Background Art

[0002] Loaders are earthwork machines widely used in construction projects such as roads, railways, buildings, hydropower, ports, and mines. Loaders need radiators to dissipate internal heat in a timely manner. Radiators usually include a heat dissipation core and a frame structure, and the core is installed inside the frame structure.

[0003] like Figure 1 The figure shows the existing radiator structure. The frame structure includes an upper frame, a lower frame and a side frame, wherein the side frame includes a U-shaped side plate and an L-shaped base, and the U-shaped side plate is welded to the L-shaped base plate. The side frame structure has the following problems:

[0004] 1. The U-shaped side panels of the side frame need to change according to the change of the core thickness. When the core thickness changes, the U-shaped side panels need to be changed accordingly, which cannot be universalized. It is necessary to prepare various types of side frame structures, which is inconvenient to manage.

[0005] 2. When the core is replaced during after-sales maintenance, due to the U-shaped side panel, the side frame needs to be disassembled first, and then the core can be repaired or replaced, which is cumbersome.

[0006] 3. The U-shaped side panel and L-shaped base in the side frame are combined, there are many welds, large welding deformation, and welding stress cannot be released.

[0007] 4. When dealing with high-load operation of the loader, the U-shaped side plate of the side frame is prone to stress concentration, which in turn damages the entire frame and reduces the service life of the radiator.

[0008] 5. The weight of the frame accounts for a large proportion. The weight of the frame (iron parts) accounts for more than half of the weight of the radiator assembly. The side frame structure is complex, and it is necessary to process the pipe opening holes on the side of the U-shaped side panel, which is difficult to process and has high cost.

[0036] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] As introduced in the background technology, the side frame structure has the following problems: the U-shaped side panel 21 of the side frame cannot be universalized and is not easy to manage. The operation is cumbersome when replacing the core during after-sales maintenance. There are many welds, large welding deformation, and welding stress cannot be released. The U-shaped side panel 21 of the side frame is prone to stress concentration, which reduces the service life of the radiator. The frame weight accounts for a large proportion, and it is necessary to process the pipe orifice clearance holes on the side of the U-shaped side panel 21, which is difficult to process and has high cost. In order to solve the above technical problems, the utility model proposes a radiator side frame 2.

[0038] like Figure 2 As shown, the radiator side frame 2 includes: a bending plate 23, a bottom plate 25 and a reinforcing rib plate 24; the bending plate 23 includes a side plate 231 and an end plate 232, the side of the side plate 231 is connected to the side of the end plate 232, and the side plate 231 and the end plate 232 are arranged vertically, so the side plate 231 and the end plate 232 constitute an L-shaped bending plate 23; the bottom plate 25 is a flat plate structure, the bending plate 23 is located on the bottom plate 25, and the side plate 231 and the end plate 232 of the bending plate 23 are both perpendicular to the bottom plate 25; the reinforcing rib plate 24 is arranged vertically on the bottom plate 25, the reinforcing rib plate 24 is coplanar with the side plate 231 of the bending plate 23, and is located on the side of the side plate 231 away from the end plate 232, and the reinforcing rib plate 24 is provided with oppositely arranged concave structures, one of which is located at the intersection of the reinforcing rib plate 24, the side plate 231 and the bottom plate 25.

[0039] The components of the side frame 2 are connected by welding, that is, the bent plate 23 and the bottom plate 25 are connected by welding, the reinforcing rib plate 24 and the bent plate 23 are connected by welding, and the reinforcing rib plate 24 and the bottom plate 25 are connected by welding.

[0040] The side frame 2 of this embodiment changes the U-shaped side panel 21 into an L-shaped bent plate 23, changes the L-shaped base 22 into a flat plate, and adds a reinforcing rib plate 24 which is coplanar with the side panel 231 of the bent plate 23. While ensuring the strength, it is not affected by the thickness of the core body. When the thickness of the core body changes by ±20mm, the size of the L-shaped bent plate 23 can remain unchanged, achieving maximum universality, reducing the models of the side frame 2, and reducing the difficulty of management.

[0041] The L-shaped bent plate 23 of the side frame 2 of this embodiment can more conveniently pull the core out from the pipe mouth side when the core is replaced during after-sales maintenance without disassembling the side frame 2, which makes the operation more convenient and saves maintenance and replacement time.

[0042] The side frame 2 of this embodiment is provided with a concave structure at the junction of the reinforcing rib plate 24, the bent plate 23 and the bottom plate 25, and a concave structure is also provided on the opposite side. While protecting the weld between the side plate 231 and the base to ensure local strength, it effectively releases stress and reduces welding deformation.

[0043] When the side frame 2 of this embodiment is used for high-load operation of the loader, the L-shaped bent plate 23 can avoid damage to the entire frame due to stress concentration through a certain plastic deformation, thereby extending the service life of the radiator.

[0044] Compared with the existing U-shaped side plate 21, the L-shaped bent plate 23 of this embodiment reduces the processing of the "giving way notch" on the pipe mouth side while ensuring the strength of the radiator assembly, saving processing costs and reducing material weight, thereby saving material costs.

[0045] like Figure 2 As shown, the side frames 2 are located at the left and right ends of the radiator core, the side plates 231 of the bent plate 23 are fitted with the end faces of the core, and the bottom of the core is located on the bottom plate 25. An upper frame 1 is provided on the upper side of the core, and threaded holes detachably connected to the core are provided on the side plates 231 of the bent plate 23. The bent plate 23 is connected to the upper frame 1 by screws, which is convenient for installation and disassembly.

[0046] The side plate 231 of the bending plate 23 is also provided with a through hole, and the positioning column passes through the through hole and is connected to the core body. When disassembling a core body, only the positioning column corresponding to the core body needs to be removed to take out the core body without disassembling the side frame 2.

[0047] A groove is provided on the bending plate 23, and the groove is located at the top of the side where the side plate 231 and the end plate 232 are connected. Figure 2As shown, the provision of the groove further reduces the damage to the entire frame caused by stress concentration, thereby extending the service life of the radiator.

[0048] like Figure 3 As shown, the reinforcing rib plate 24 is a flat plate structure, and a first concave structure 241 and a second concave structure 242 are provided at both ends of the width direction of the reinforcing rib plate 24, wherein the first concave structure 241 is located at the intersection of the reinforcing rib plate 24 and the side plate 231 and the bottom plate 25. The first concave structure 241 and the second concave structure 242 are both arc-shaped profiles, and the position of the second concave structure 242 is higher than the position of the first concave structure 241. It can be understood that in other embodiments, the two concave structures can also adopt profiles of other shapes. The reinforcing rib plate 24 at the bottom of the left and right frames adopts the form of arc transition on both sides, which protects the weld between the side plate 231 and the base, effectively releases stress, and reduces welding deformation.

[0049] Therefore, the side frame 2 has low cost, light weight, simple structure, easy processing, reliable performance and high cost performance.

[0050] Based on the above radiator side frame 2, this embodiment also provides a loader radiator, including a core, an upper frame 1, a lower frame 3 and a side frame 2, the side frame 2 is located at both ends of the core, the upper end of the side frame 2 is detachably connected to the upper frame 1, and the lower end of the side frame 2 is detachably connected to the lower frame 3. Figure 4 As shown, the upper frame 1 includes a top plate 11, which is a U-shaped plate having a U-shaped opening, and the U-shaped opening is arranged away from the core body. Figure 5 As shown, a hanging plate 12 is provided on the top plate 11, and the hanging plate 12 is perpendicular to the flat plate at the bottom of the top plate 11, and a hanging hole 121 is provided at the bottom of the hanging plate 12. In this embodiment, the U-shaped plate of the upper frame 1 is arranged upward to improve versatility and avoid interference when disassembling the core body, and the hanging plates 12 are added at both ends, which not only facilitates hanging, but also increases the strength of both ends of the upper frame 1.

[0051] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the protection scope of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
