Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a split-installation staggered H-shaped post-processing support assembly. Background Technology

[0002] With the continuous development of the construction machinery industry, my country has implemented regulations on exhaust emissions from non-road excavators. Only those that meet the fourth-stage emission standards can be sold and used. Therefore, most non-road excavators need to be equipped with corresponding aftertreatment support assemblies. However, large excavators have large engine displacements, resulting in larger aftertreatment assemblies. Traditionally, most aftertreatment support assemblies are integrated into a single unit.

[0003] In the prior art, patent CN210396868U discloses an engine aftertreatment bracket assembly and engineering machinery, in which the bottom bracket and the aftertreatment mounting bracket are welded together as a whole. This technology has the following problems: 1. Vibration and stress transmission are direct and intense: Excavators generate powerful impact loads and intense vibrations during operation. The rigid connection between the bottom bracket welding and the post-processing mounting bracket welding will result in high stress at the connection position, which can easily lead to fatigue damage of the welded parts and cracking of the weld.

[0004] 2. Difficulty in maintenance and disassembly: When the main pump or a component under the aftertreatment bracket assembly fails, safety inspection is required. Since the bottom bracket and the aftertreatment mounting bracket are welded together as a whole, the entire assembly needs to be disassembled on site, which is time-consuming, labor-intensive, and inconvenient for later maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide a split-installation staggered H-shaped post-processing bracket assembly that can solve the technical problem of low strength of existing post-processing brackets.

[0006] To achieve the above objectives, the present invention proposes a split-installation staggered H-shaped post-treatment support assembly, including a bottom support, wherein the top of the bottom support is detached and installed with a mounting bracket via bolts; The mounting frame is formed by a pair of parallel horizontal beams and a pair of parallel vertical beams. It is located at the center of the two horizontal beams and a pair of support beams are fixed to the two horizontal beams. A first short beam is fixedly installed between the support beams. The support beams are connected to the vertical beams on one side by a second short beam. The first and second short beams are spaced apart along the length of the vertical beams. The post-processing equipment is fixedly installed on the top of the mounting frame by bolts.

[0007] Further configured, a plurality of first screw holes are opened along the first short beam, and a plurality of second screw holes are set on the support beam in the direction from the connection point between the support beam and the first short beam to the front crossbeam. A plurality of third screw holes are set in the length direction of the front crossbeam. The mounting frame is disassembled and installed with the post-processing equipment by means of bolts in the rectangular screw hole group formed by the first screw holes, the second screw holes and the third screw holes. The layout not only enhances the planar rigidity and torsional resistance of the installation, but also makes the weight of the equipment more evenly distributed on each support point of the mounting frame, avoiding local overload.

[0008] Further configured, the bottom support includes four L-shaped beams arranged perpendicular to the ground. The top of the L-shaped beams has a circular hole, and the circular hole of the L-shaped beam is connected to the circular hole of the mounting bracket by bolts. The L-shaped beam structure has both vertical load-bearing and lateral bending resistance, which effectively improves the overall rigidity and anti-overturning ability of the bottom support.

[0009] Further, a partition is bolted to the inner side of the bottom support, which can be used as a reinforcing rib to effectively suppress the deformation and swaying of the L-shaped beam under stress, thereby improving the lateral stiffness and stability of the bottom support.

[0010] A further configuration is provided, wherein a support plate is fixedly installed on one side of the L-shaped beam, the support plate is connected to the mounting frame by bolts, the top surface of the L-shaped beam is set along the width direction of the mounting frame, the top surface of the support plate is set along the length direction of the mounting frame, the support plate is fixedly installed on one side of the L-shaped beam, and the support plate is connected to the mounting frame by bolts, thereby realizing a dual connection and force transmission between the bottom support and the mounting frame in both length and width directions.

[0011] A further configuration involves fixing a cover plate above the mounting frame, with a round hole penetrating the cover plate. Bolts pass through the round hole and are then fixedly connected to the processing equipment after passing through the mounting frame. Fixing the cover plate above the mounting frame and connecting the bolts through the cover plate to the mounting frame and then to the processing equipment increases the coverage and protection of the connection area.

[0012] Further, the cover plate has several circular holes on its top and near one side, and the support beam has corresponding circular holes. The C-shaped beam is installed by bolts through the circular holes. The C-shaped beam is installed upside down on the top of the cover plate. The C-shaped beam can be detachably installed on the top of the cover plate by bolts, providing additional auxiliary support or fixing points for post-processing equipment or related pipelines.

[0013] Further, the cover plate has several circular holes on its top and near the other side, and the support beam has corresponding circular holes. The box beam can be installed by bolts through these circular holes. The box beam can also be installed by bolts on the other side of the cover plate, which further enhances the structural strength and functional modularity of the support assembly.

[0014] Further configuration involves the four vertical beams arranged in parallel, with pads fixedly installed at the bottom of the two vertical beams closest to the partition. The four L-shaped vertical beams are arranged in parallel, with pads fixedly installed at the bottom of the two vertical beams closest to the partition, which can alleviate the additional stress caused by uneven ground.

[0015] Further, two bottom fixed angle steels are installed on the side away from the cover plate, with the inner angle of the angle steel corresponding to the outer angle of the upright beam. The angle steels are arranged along the length direction of the mounting frame, and the length of the angle steels is greater than the interval between the outer sides of the upright beams. The angle steels form a continuous reinforcing frame along the length direction, which significantly enhances the integrity and deformation resistance of the bottom support in this direction.

[0016] The beneficial effects of one or more of the above technical solutions: 1. The mounting frame of the fixed post-processing equipment of the present invention is composed of 8 horizontal beams, 2 vertical beams, 2 L-shaped beams and 2 mounting frames. The vertical beams and L-shaped beams are connected to the upper end of the mounting base plate by welding. The 8 horizontal beams form multiple staggered "H"-shaped layouts and are welded to the lower end of the mounting base plate. The first H-shaped bracket is formed by the support beam of the mounting frame and the first short beam. The second H-shaped support frame is formed by setting the second short beam between the support beam and the vertical beam. The first short beam and the second short beam are set at intervals, thereby forming a pair of set H-shaped reinforcing structures. At the same time, the post-processing equipment is fixed to the lower half of the H-shaped bracket by bolts. The force of the post-processing equipment is transferred to the second H-shaped bracket through the first H-shaped bracket, and finally to the upper C-shaped beam and the lower bottom bracket. The advantage of the "H"-shaped layout is that it disperses the weight of the post-processing equipment, making the structure more stable and the force on the mounting base plate more even.

[0017] 3. The bottom support is welded together by four L-shaped beams, four crossbeams and four partitions. The four L-shaped beams serve as the bottom plate support structure and are welded to the post-processing mounting frame by bolts. At the same time, the post-processing mounting frame is connected to the post-processing equipment by bolts. During equipment maintenance, the bolts can be removed for quick disassembly and maintenance. Attached Figure Description

[0025] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0026] A split-mounted staggered H-type post-treatment bracket assembly, as shown in the reference. Figures 1 to 5 The system includes a bottom support 1, with a mounting plate 2 detachably mounted on top of the bottom support 1 via bolts. The mounting plate 2 is formed by a pair of parallel horizontal beams 3 and a pair of parallel vertical beams 4, located at the center of the two horizontal beams 3, and a pair of support beams 5 are fixed to the two horizontal beams 3. A first short beam 6 is fixedly installed between the support beams 5, and the support beams 5 are connected to one side of the vertical beam 4 via a second short beam 7. The first short beam 6 and the second short beam 7 are spaced apart along the length of the vertical beam 4. The post-treatment equipment 8 is fixedly mounted on top of the mounting plate 2 via bolts. Generally, during equipment installation, the main pump is also installed simultaneously below the mounting plate 2 via bolts. This is because the post-treatment equipment and main pump are heavy after installation, and the working support assembly works in a vibration environment. The connection points of equipment such as the main pump are subjected to forces from multiple directions, which can easily lead to fatigue damage of the welded parts. Therefore, in this embodiment, the first H-shaped bracket is formed by the support beam and the first short beam of the mounting frame. A second short beam is set between the support beam and the longitudinal beam to form a second H-shaped support frame. The first and second short beams are spaced apart to form a pair of H-shaped reinforcing structures. At the same time, the post-processing equipment is fixed to the lower half of the H-shaped bracket with bolts. The force of the post-processing equipment is transferred from the first H-shaped bracket to the second H-shaped bracket, and finally to the upper C-shaped beam and the lower bottom bracket. The advantage of the "H"-shaped layout is that it disperses the weight of the post-processing equipment, making the structure more stable and the stress on the mounting base plate more even. Specifically, this is mainly reflected in the following two aspects: The double H-shaped structural layout consists of two parts: the first H-shaped support structure, formed by support beam 5 and the first short beam 6, directly bears the main weight of the post-processing equipment 8 and transfers the load to both sides through support beam 5; the second H-shaped support structure, formed by support beam 5, the second short beam 7, and the longitudinal beam 4, receives the load transferred from the first H-shaped structure and further distributes it to the rectangular frame enclosed by the longitudinal beam 4 and the transverse beam 3. This staggered arrangement of the double H-shaped frame forms a stepped mechanical transfer path, avoiding load concentration on a single plane or node and significantly reducing local stress.

[0027] Load distribution mechanism: By setting two H-shaped structures longitudinally at intervals, the dynamic loads of the post-processing equipment 8, such as vibrations and impacts, can be absorbed and redistributed along the length of the support beam 5 by the connection points of multiple nodes, the first short beam 6 and the second short beam 7, thereby improving the fatigue resistance and overall stiffness of the structure. Simultaneously, the rectangular frame, as the final load-bearing foundation, ensures that the load is evenly transferred to the bottom support 1.

[0028] Several first screw holes 9 are made along the first short beam 6, and several second screw holes 10 are set on the support beam 5 in the direction from the connection point between the support beam 5 and the first short beam 6 to the front crossbeam 3. Several third screw holes 11 are set along the length of the front crossbeam 3. The mounting plate 2 is disassembled and installed with the post-processing equipment 8 through the rectangular screw hole group formed by the first screw holes 9, the second screw holes 10, and the third screw holes 11. By setting the first screw holes 9, the second screw holes 10, and the third screw holes 11 on the first short beam 6, the support beam 5, and the front crossbeam 3 respectively, and forming a rectangular screw hole group, the post-processing equipment 8 can be stably installed through multi-point, rectangularly distributed bolt connections. This layout not only enhances the planar rigidity and torsional performance of the installation, but also makes the weight of the equipment more evenly distributed on each support point of the mounting plate 2, avoiding local overload, and further improving the reliability of the connection and the stability of equipment operation. In this embodiment, the force distribution of the bolt group is optimized by using the rectangular bolt group formed by the first short beam 6, the support beam 5, and the crossbeam 3. Specifically, the directional layout of the rectangular bolt hole group: by designing the bolt hole group as a rectangle with its long side parallel to the crossbeam 3 and its short side parallel to the longitudinal beam 4, the bolt connection points are matched with the mechanical properties of the H-shaped structure. The bolts in the transverse direction of the long side mainly resist transverse vibration and torsional loads, while the bolts in the longitudinal direction of the short side resist longitudinal vibration and bending loads. This layout optimizes the stress distribution of the bolt group.

[0029] Multi-point bolt transfer path: The load of the post-processing device 8 is first transferred to the core area of ​​the first short beam 6 and support beam 5 (the first H-shaped structure) through multiple bolt points of the rectangular bolt hole group. Then, it is transferred along the support beam 5 to the second short beam 7 and longitudinal beam 4 (the second H-shaped structure), and finally diffused to the entire rectangular frame. This transfer path ensures that the load is initially dispersed within the first H-shaped structure and then further dispersed through the second H-shaped structure, effectively reducing the stress peak at individual connection points and improving the reliability and durability of the connection.

[0030] The bottom support 1 includes four L-shaped beams 12 perpendicular to the ground. Each L-shaped beam 12 has a circular hole 13 at its top, which is bolted to the circular hole 13 of the mounting plate 2. The bottom support 1, with its four L-shaped beams 12 perpendicular to the ground and bolted to the mounting plate 2 via the top circular holes 13, forms a stable three-dimensional support frame. The L-shaped beam 12 structure combines vertical load-bearing capacity with lateral bending resistance, effectively improving the overall rigidity and anti-overturning properties of the bottom support 1. The bolted connection method facilitates adjustment of the installation height and level, adapting to the installation requirements of different machine models or ground surfaces, enhancing versatility and installation convenience.

[0031] The partition plate 14 is bolted to the inner side of the bottom support 1, enhancing the internal structural connection and integrity of the support. The partition plate 14 can be used as a reinforcing rib, effectively suppressing the deformation and swaying of the L-shaped beam 12 under stress, thus improving the lateral stiffness and stability of the bottom support 1. The bolted connection facilitates the installation, replacement, or later addition of the partition plate 14, providing a flexible and adjustable solution for structural reinforcement.

[0032] A support plate 15 is fixedly installed on one side of the L-shaped beam 12. The support plate 15 is connected to the mounting plate 2 by bolts. The top surface of the L-shaped beam 12 is set along the width direction of the mounting plate 2, and the top surface of the support plate 15 is set along the length direction of the mounting plate 2. The support plate 15 is fixedly installed on one side of the L-shaped beam 12, and the support plate 15 is connected to the mounting plate 2 by bolts, realizing a dual connection and force transmission between the bottom bracket 1 and the mounting plate 2 in both length and width directions. This design expands the connection contact surface, makes the load distribution more uniform, and enhances the shear and tensile strength of the connection node. At the same time, the support plate 15 provides additional auxiliary support points for the mounting plate 2, further improving the stability and load-bearing capacity of the mounting plane.

[0033] A cover plate 16 is fixedly installed on top of the mounting plate 2. A circular hole 13 passes through the cover plate 16, and bolts pass through the circular hole 13 through the mounting plate 2 to be fixedly connected to the post-processing equipment 8. Fixing the cover plate 16 on top of the mounting plate 2 and connecting the bolts through the cover plate 16 to the mounting plate 2 and the post-processing equipment 8 increases the coverage and protection of the connection area. The cover plate 16 can prevent dust, mud, and other foreign objects from entering the bolt connection, reducing the risk of corrosion and loosening. At the same time, the cover plate 16 itself can provide local reinforcement, improving the flatness and rigidity of the top surface of the mounting plate 2, which is beneficial to the stable installation of the post-processing equipment 8.

[0034] Several circular holes 13 are formed on the top of the cover plate 16 and near one side. The support beam 5 has corresponding circular holes 13. C-shaped beams 17 are installed by bolting through these holes 13. The C-shaped beams 17 are inverted and installed on the top of the cover plate 16. The C-shaped beams 17, detachably installed on the top of the cover plate 16 via bolts, provide additional auxiliary support or fixing points for the post-processing equipment 8 or related pipelines. The inverted installation of the C-shaped beams 17 forms a groove or bearing surface, which can be used for guidance, limiting, or sharing part of the load, enhancing the functional expandability and adaptability of the support assembly. The detachable design allows for flexible adjustment or addition of auxiliary components according to actual needs.

[0035] Several circular holes 13 are formed on the top of the cover plate 16 and near one side. The support beam 5 has corresponding circular holes 13. The box girder 18 is installed and removed using bolts through these holes 13. The box girder 18 is detachably installed on the other side of the cover plate 16 using bolts, further enhancing the structural strength and modularity of the support assembly. The box girder 18 has high bending and torsional resistance, effectively improving the overall rigidity of that side and serving as an integrated channel for wiring harnesses and conduits. The modular design of the box girder 18 facilitates standardized production and rapid assembly, improving product configurability and maintenance convenience.

[0036] Four L-shaped beams 12 are arranged in parallel, with pads 19 fixedly installed at the bottom of the two L-shaped beams 12 closest to the partition plate 14. The pads 19 increase the contact area between the L-shaped beams 12 and the ground or frame, improving stress distribution and preventing excessive local pressure from causing sinking or damage. Simultaneously, the pads 19 act as leveling agents, ensuring the support assembly is installed horizontally, improving overall stability, and mitigating additional stress caused by uneven ground.

[0037] Angle steel 20s are fixedly installed at the bottom of two L-shaped beams 12 on the side away from the cover plate 16. The inner angles of the angle steel 20s correspond to the outer angles of the L-shaped beams 12. The angle steel 20s are arranged along the length of the mounting plate 2, and their length is greater than the spacing between the outer surfaces of the L-shaped beams 12. The angle steel 20s form a continuous reinforcing frame along the length of the mounting plate 2, significantly enhancing the integrity and deformation resistance of the bottom support 1 in this direction. The angle steel 20 structure also guides installation positioning and prevents lateral displacement of the support. Furthermore, its edges provide additional mounting holes for easy connection with other components, enhancing the integration and expandability of the support assembly.

[0038] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
