Description

Platforms and construction machinery Technical Field

[0001] This invention relates to the field of supporting components for engineering machinery, specifically to a platform and engineering machinery. Background Technology

[0002] As an indispensable core component of construction machinery equipment, the walkway serves as a platform for operators to move around and for equipment maintenance. It also bears the responsibility of installing, fixing, and supporting various covering parts and functional components. The reliability, universal adaptability, and installation precision of the walkway directly affect the overall safety performance, manufacturing cost, and appearance quality of the construction machinery equipment.

[0003] Therefore, continuously optimizing the structural design of the walkway and improving its overall performance while ensuring controllable manufacturing costs has always been a key research and development direction in this field.

[0004] However, most of the walkway structures currently used in the industry adopt a design of thin plates welded together with reinforcing ribs. This structure has unresolved technical pain points in actual production and engineering applications: the walkway has a very low degree of universality. The fixing of components such as wire harnesses and fasteners requires corresponding holes to be drilled or special brackets to be welded on the walkway surface or reinforcing ribs. Due to the influence of different machine models, different configurations of equipment interface forms, and differences in the arrangement of wire harnesses and components, the walkway is difficult to achieve cross-model universality and cannot be adapted to the large-scale standardized processing operation mode, which restricts the improvement of production efficiency and the optimization of manufacturing costs. Summary of the Invention

[0005] In view of this, the present invention provides a walkway and engineering machinery to solve the problem that "the walkway has low versatility and is difficult to adapt to different models".

[0006] In a first aspect, the present invention provides a walkway plate for use in engineering machinery. The engineering machinery includes a frame, and the walkway plate includes multiple modules. Each module includes a module body, a mating part, and a fixing part. The module body is a plate-shaped structure, and the mating part is located on the edge of the module body. Adjacent modules are mated together through the mating part to form a plate. Multiple fixing parts are provided, and the fixing parts are located on the module body and are used to connect with the frame. At least one end of the module is provided with a fixing part. The module is made of aluminum alloy profile.

[0007] Beneficial Effects: This solution designs the walkway as a plate-like structure assembled from multiple aluminum alloy profile modules. The modules interlock via edge fittings to form a unified plate. Multiple fixing points for connection to the frame are provided on each module, with at least one fixing point located at one end. This structure not only enables modular production and rapid assembly of the walkway, significantly reducing manufacturing and maintenance costs, but also, due to the use of aluminum alloy profiles, greatly reduces overall weight while maintaining structural strength, improving corrosion resistance and service life. Furthermore, the layout of the fixing points allows mounting holes to be concealed within the modules or at the ends, avoiding safety hazards caused by exposed bolts, improving the aesthetics and safety of the walkway, and facilitating flexible arrangement of accessories such as wiring harnesses. This comprehensively enhances the reliability, precision, and assembly efficiency of the engineering machinery walkway.

[0008] In one optional embodiment, the plurality of modules includes at least two first modules; the mating part includes at least one of a protrusion and a recess; the first module includes two reinforcing parts, which are respectively disposed at opposite ends of the module body of the first module, and the two reinforcing parts are respectively provided with a protrusion and a recess; two adjacent first modules are connected by a protrusion on one and a recess on the other.

[0009] Beneficial effects: This embodiment achieves modular splicing of the walkway by combining at least two first modules. The mating parts include protrusions and recesses. Through the combination and splicing of the protrusions and recesses and the cooperation between the fixing parts and the frame, a reliable combined structure is formed between the modules, and the walkway is tightly fixed to the frame, thereby improving the strength of the overall structure.

[0010] In one optional embodiment, the plurality of modules further includes at least one second module, the second module including a reinforcing portion, the reinforcing portion of the second module being disposed on the side of the module body of the second module close to the first module; a protrusion or a recess is disposed on the reinforcing portion of the second module and is spliced ​​and fitted with the mating portion of the first module.

[0011] Beneficial effects: This embodiment introduces a second module with a different structure from the first module. The second module matches the recessed or protruding part provided on the end of the first module of the platform. The second module can be quickly spliced ​​and matched with the first module, so that the platform can meet the needs of more usage scenarios.

[0012] In one optional embodiment, the second module includes a first sub-module, a second sub-module, and a connecting part. The first sub-module and the second sub-module are arranged at an angle. A protrusion or a recess is provided on the first sub-module, a fixing part is provided on one side of the first sub-module, and a connecting part is provided on the side of the second sub-module facing the frame. Adjacent second sub-modules are connected by the connecting part.

[0013] Beneficial effects: The second module is composed of the first and second sub-modules and is set at an angle to form a structure with a bend, which enhances the structural rigidity and load-bearing capacity of the second module. At the same time, the side of the second sub-module facing the frame is provided with a connecting part, and adjacent second sub-modules are spliced ​​together through the connecting part, thereby expanding the overall size of the walkway in the length direction.

[0014] In one optional implementation, the second submodule is further provided with a vertical plate, which is located on one side of the second submodule and is set at an angle to the second submodule. The vertical plate is connected to the functional components of the frame.

[0015] Beneficial effects: The upright plate extends away from the platform surface and can be pre-installed with mounting holes, slots, or threaded connections for connecting functional components on the frame (such as guardrails, mudguards, or electrical component mounting plates). Through this structural design, the second sub-module not only bears the load of the platform but also serves as a mounting base for the functional components. This allows the load of the functional components to be directly transferred to the upright plate, and then to the frame via the second sub-module and the fixing parts. This avoids the need for additional holes or welded supports on the platform surface, thereby improving the overall integrity and structural strength of the platform.

[0016] In one alternative implementation, the second submodule has a groove on the side facing away from the upright plate, the groove extending along the opposite ends of the second submodule, and the groove is used to install functional components that are compatible with the walkway plate.

[0017] Beneficial effects: The groove is used to install functional components on the walkway or rack, making the structure more compact.

[0018] In one alternative embodiment, the first module is further provided with a support member on the side near the frame, the support member extending toward the frame and abutting against the frame; and / or, the side of the walkway away from the fixed part is provided with an anti-slip part at least partially, the anti-slip part being a plurality of protrusions extending in the direction away from the walkway.

[0019] Beneficial effects: When the first module is connected to the frame via the fixing part, the end of the support member abuts tightly against the frame surface, thus forming an auxiliary support point between the first module and the frame. Through this structural design, the support member not only enhances the structural strength and bending stiffness of the first module itself, but also directly transfers part of the load borne by the walkway to the frame, dispersing the force on the fixing part and avoiding localized stress concentration. Simultaneously, the abutting fit between the support member and the frame effectively suppresses vibration and displacement of the walkway during equipment operation, improving the overall stability and fatigue resistance of the walkway.

[0020] Raised structures are incorporated into the surface of the walkway as anti-slip features. These raised structures effectively increase the coefficient of friction between the foot surface and the shoe sole, providing reliable anti-slip performance in rainy, oily, or muddy conditions, preventing operators from slipping and falling, and significantly improving the safety of the walkway. Simultaneously, the raised structures form natural drainage and mud-removal channels, preventing water or mud accumulation from reducing the anti-slip effect. Furthermore, the raised structures are integrally molded with the walkway body, requiring no additional adhesives or welding, ensuring the structural integrity and durability.

[0021] In one alternative embodiment, the fixing part has a receiving space, and at least a portion of the fixing part is connected to the frame by fasteners. The receiving space is used to accommodate the fasteners. The fixing part is provided in at least two locations, and at least one location corresponds to the recessed part.

[0022] Beneficial effects: The fixing part is located between the walkway and the frame and has a accommodating space, allowing the fasteners to be installed in the accommodating space. Through this structural design, the fasteners are completely hidden inside the fixing part, avoiding the bolts being exposed on the walkway surface, eliminating the safety hazard of tripping pedestrians, and improving the overall aesthetics and refinement of the walkway.

[0023] In one alternative embodiment, the two ends of the fixing part and the connecting part extend to two opposite edges of the module body, and at least one end is flush with the edge.

[0024] Beneficial effects: The fixing part, serving as a slot structure on the first sub-module for connection to the frame, and the connecting part, serving as a structure on the second sub-module for lateral splicing of adjacent modules, are both designed to extend along the length direction, with their starting and ending ends aligned with the two end edges of the walkway plate along the length direction, respectively. This structural design allows the fixing and connecting parts to cover the entire length of the walkway plate, ensuring that the installation positions of fasteners and the lateral connections between modules are distributed at both ends of the walkway plate, thus forming uniform stress support along the length direction and avoiding localized stress concentration.

[0025] Secondly, the present invention also provides an engineering machine, including the walkway mentioned in the first aspect.

[0026] The technical solution proposed in this application has at least the following technical effects: This invention provides a modular walkway, which is designed as a plate-like structure spliced ​​from multiple aluminum alloy profile modules. Each module cooperates with each other through edge mating parts to form an integral plate body, and multiple fixing parts for connecting with the frame are provided on the main body of the module, with at least one fixing part provided at one end. This structure not only realizes the modular production and rapid assembly of the walkway, significantly reducing manufacturing and maintenance costs, but also greatly reduces the overall weight while ensuring structural strength due to the use of aluminum alloy profiles, improving corrosion resistance and service life. In addition, the layout design of the fixing parts allows the mounting holes to be hidden inside the module or at the end, avoiding the safety hazards caused by exposed bolts, improving the aesthetics and safety of the walkway, and facilitating the flexible arrangement of accessories such as wire harnesses, comprehensively improving the reliability, precision and assembly efficiency of the engineering machinery walkway.

[0035] A walkway is a structure installed on the frame or platform of construction machinery (such as truck cranes, excavators, and road rollers) for walking and working. Its main function is to provide operators with a safe space for standing, walking, and maintenance, while also serving as a mounting platform for various functional components such as covers, pipelines, and guardrails. Walkways typically need to possess good load-bearing capacity, anti-slip properties, weather resistance, and compatibility with the overall machine structure, making them an important component in construction machinery that combines safety and functionality.

[0036] As an indispensable core component of construction machinery, the walkway serves as a platform for operators to move around and for equipment maintenance. It also supports the installation, fixing, and load-bearing of various covers and functional parts. The reliability, versatility, and precision of its installation directly impact the overall safety performance, manufacturing costs, and appearance quality of the construction machinery. Therefore, continuously optimizing the structural design of the walkway to improve its overall performance while ensuring controllable manufacturing costs has always been a key research and development direction in this field.

[0037] However, most of the walkway structures currently used in the industry adopt a design of thin plates welded together with reinforcing ribs. This structure has unresolved technical pain points in actual production and engineering applications: the walkway has a very low degree of universality. The fixing of components such as wire harnesses and fasteners requires corresponding holes to be drilled or special brackets to be welded on the walkway surface or reinforcing ribs. Due to the influence of different machine models, different configurations of equipment interface forms, and differences in the arrangement of wire harnesses and components, the walkway is difficult to achieve cross-model universality and cannot be adapted to the large-scale standardized processing operation mode, which restricts the improvement of production efficiency and the optimization of manufacturing costs.

[0038] This solution provides a modular walkway platform that uses aluminum alloy profiles instead of the traditional thin-plate welded reinforcing rib structure. The walkway platform is composed of multiple standardized modules (including first module 1, second module 2, and their sub-modules) assembled through a splicing structure, allowing for flexible adjustment of length and width according to actual needs. The modules have internal slot structures for fixing hexagonal head bolts and cable clips, achieving concealed arrangement of fasteners and wiring harnesses; the platform surface has anti-slip protrusions to improve walking safety; simultaneously, the connection points between the modules and the frame 5 are integrated into the reinforcing section 3, avoiding exposed bolts. The overall structure achieves a unity of modularity, lightweight design, and high integration.

[0039] Compared to traditional walkways, this solution offers the following significant advantages: First, its modular design enables standardized production and rapid on-site assembly, reducing manufacturing and maintenance costs. Second, the concealed mounting structure eliminates safety hazards caused by exposed bolts, enhancing the overall precision of the machine. Third, the profile structure avoids welding defects, increases vibration resistance and fatigue life, and adapts to the harsh working conditions of construction machinery. Fourth, the flexible wiring harness arrangement facilitates compatibility with multiple vehicle models. This modular walkway is widely used in various types of construction machinery and has significant potential for widespread adoption and promising industry prospects.

[0040] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0041] The embodiments of the present invention are described below with reference to Figures 1 to 5.

[0042] According to an embodiment of the present invention, in a first aspect, referring to FIG1, a walkway is provided for use in engineering machinery. The engineering machinery includes a frame 5. The walkway includes multiple modules. Each module includes a module body 101, a mating part, and a fixing part 104. The module body 101 has a plate-like structure. The mating part is located at the edge of the module body 101. Adjacent modules are mated to form a plate body through the mating part. Multiple fixing parts 104 are provided. The fixing parts 104 are located on the module body 101 and are used to connect with the frame 5. At least one end of the module is provided with a fixing part 104. The module is made of aluminum alloy profile.

[0043] Specifically, each module includes a module body 101, a mating part, and a fixing part 104. The module body 101 is a plate-like structure made of aluminum alloy profile, combining lightweight and high strength. The mating part is located at the edge of the module body 101 and is used for splicing and mating between adjacent modules. As an optional implementation, the mating part can adopt a structure of protrusion and concavity, such as an arc-shaped outward protrusion structure and an inward concavity structure, to ensure a stable splicing and easy assembly and disassembly.

[0044] It should be understood that the protrusion 102 and the recess 103 are not limited to adopting an arc-shaped structure, but include, but are not limited to, adopting a rectangular or I-shaped structure that allows adjacent modules to be spliced ​​and combined.

[0045] Furthermore, adjacent modules, after mating, form a complete walkway panel. Multiple fixing parts 104 are provided, located on the module body 101, for fixed connection with the frame 5 of the construction machinery. To further optimize the installation layout, at least one end of the module is provided with a fixing part 104, allowing bolts and other fasteners to be hidden at the module end or inside, avoiding tripping risks caused by exposed fasteners, and improving overall aesthetics.

[0046] In this embodiment, the module is an aluminum alloy extruded profile, which can be extruded through a mold, making it easy to mass-produce. It can also be cut to length or combined with modules of different widths according to actual needs, achieving flexible configuration.

[0047] In addition, referring to Figures 2 to 5, the fixing part 104 has a receiving space for accommodating and limiting hexagonal head bolts or pipeline fixing clips, further optimizing the wiring harness layout and installation efficiency.

[0048] In one embodiment, referring to FIG2, the plurality of modules include at least two first modules 1; the mating part includes at least one of a protrusion 102 and a recess 103; the first module 1 includes two reinforcing parts 3, which are respectively disposed at opposite ends of the module body 101 of the first module 1, and the two reinforcing parts 3 are respectively provided with a protrusion 102 and a recess 103; two adjacent first modules 1 are connected by a protrusion 102 on one and a recess 103 on the other.

[0049] In this embodiment, the walkway includes at least two first modules 1. The first module 1 is formed by extrusion of aluminum alloy profiles, and reinforcing parts 3 are respectively provided at both ends along the width direction of the walkway to improve the load-bearing capacity and bending stiffness of the module.

[0050] Furthermore, multiple fixing parts 104 are disposed on one side of the first module 1, facing the frame 5 of the engineering machinery, for connection with the frame 5. The fixing part 104 can be a slot structure extending along any edge of the module body 101, capable of accommodating fasteners (such as the head of a hexagonal head bolt) and restricting their rotation, thereby achieving concealed installation of the fasteners. Fixing parts 104 are provided at least at opposite ends of the first module 1 to ensure reliable multi-point connection between the platform and the frame 5, preventing localized loosening. Through this structure, the platform not only achieves modular assembly but also optimizes the installation method, improving overall reliability and operational safety.

[0051] Specifically, the fixing part 104 can be configured as a slot structure, with an internal receiving space for accommodating the head of fasteners such as hexagonal head bolts. The slot's size design prevents the bolt head from rotating, thus achieving pre-installation and concealed fixing of the fasteners. The fixing part 104 is provided in at least two locations to ensure reliable multi-point connection between the platform and the frame 5, avoiding loosening or displacement caused by single-point force.

[0052] In this embodiment, at least one fixing part 104 is provided corresponding to the recessed part 103, that is, the fixing part 104 is positioned to correspond to the recessed part 103 at one end of the first module 1, so that the installation position of the fastener and the module splicing structure form a reasonable layout, which optimizes space utilization and enhances the connection strength at the splicing point.

[0053] In one embodiment, referring to Figures 3 to 5, the plurality of modules further includes at least one second module 2. The second module 2 includes a reinforcing part 3, which is disposed on the side of the module body 101 of the second module 2 close to the first module 1. A protrusion 102 or a recess 103 is disposed on the reinforcing part 3 of the second module 2 and is spliced ​​and fitted with the mating part of the first module 1.

[0054] In this embodiment, the walkway further includes at least one second module 2. Specifically, the second module 2 is also made of extruded aluminum alloy profile, and a reinforcing part 3 is provided on its side near the first module 1. The reinforcing part 3 has a protrusion 102 or a recess 103. By matching the recess 103 or protrusion 102 provided on the first module 1 at the end of the walkway, the second module 2 can be quickly spliced ​​and fitted with the first module 1.

[0055] Furthermore, the second module 2 is a module located on the edge of the walkway, with a protrusion 102 or a recess 103 at one end that cooperates with the first module 1, and a structure at the other end that can cooperate with the frame 5, making the walkway structure more robust.

[0056] In one embodiment, referring to Figures 3 to 5, the second module 2 includes a first sub-module 201, a second sub-module 202, a connecting part 2021, and a fixing part 104. The first sub-module 201 and the second sub-module 202 are arranged at an angle. A protrusion 102 or a recess 103 is provided on the first sub-module 201. The fixing part 104 is provided on one side of the first sub-module 201 and can be connected to the frame 5. The connecting part 2021 is provided on the side of the second sub-module 202 facing the frame 5. Adjacent second sub-modules 202 are connected through the connecting part 2021.

[0057] In this embodiment, the second module 2 is further constructed to include a first sub-module 201 and a second sub-module 202, which are arranged at an angle, for example, forming a shaped structure, to enhance the structural rigidity and load-bearing capacity of the second module 2. A protrusion 102 or a recess 103 for splicing with the first module 1 is provided on the first sub-module 201, enabling the second module 2 to reliably connect with the first module 1 at the end of the platform. Simultaneously, a fixing part 104 is provided on one side of the first sub-module 201, which connects to the frame 5 to ensure the installation stability of the second module 2 in the width direction. A connecting part 2021 is provided on the side of the second sub-module 202 facing the frame 5, allowing adjacent second sub-modules 202 to be spliced ​​together via the connecting part 2021, thereby expanding the overall size of the platform in the length direction.

[0058] Through this structural design, the second module 2 not only extends the width of the walkway but also enables modular expansion in length. The connecting part 2021 allows multiple second modules 2 to be connected side-by-side along the length, forming a longer walkway working surface to meet the diverse platform length requirements of different engineering machinery. Simultaneously, the angled structure between the first sub-module 201 and the second sub-module 202 enhances the bending and torsional resistance of the second module 2, making it more stable and reliable when bearing personnel walking and equipment installation loads. This modular combination further improves the versatility and adaptability of the walkway, reducing manufacturing and assembly complexity.

[0059] Furthermore, the second submodule 202 can be further connected to relevant functional components of the frame 5 to enhance the overall structural strength of the walkway and the frame 5, and to expand the functional integration of the walkway. Specifically, the second submodule 202 is detachably connected to the functional components (such as guardrails, handrails, pipeline supports, electrical component mounting plates, etc.) that are matched with the frame 5. Through this connection, the second submodule 202 not only serves as the load-bearing structure of the walkway, but also acts as the mounting base for the functional components, allowing the load of the functional components to be directly transferred to the second submodule 202, and then transferred to the frame 5 via the fixing part 104. This avoids the need for additional openings or welding of supports on the surface of the first module 1 or the first submodule 201, thereby improving the overall integrity and structural strength of the walkway.

[0060] Furthermore, the second sub-module 202 is located at the edge of the frame 5. The L-shaped second module 2 cooperates with the first module 1 to form a semi-enclosed structure covering the frame 5. Through the semi-enclosed structure, there are multiple fixed points at various angles between the walkway and the frame 5, which makes the structure after the walkway and the frame 5 are combined have higher strength.

[0061] In one embodiment, referring to Figures 3 to 5, the second submodule 202 is further provided with a vertical plate 2022. The vertical plate 2022 is disposed on one side of the second submodule 202 and is set at an angle to the second submodule 202. The vertical plate 2022 is connected to the functional components of the frame 5.

[0062] In this embodiment, the second submodule 202 also includes a vertical plate 2022. This vertical plate 2022, as a component of the second submodule 202, is disposed on one side of the second submodule 202 and is angled to it, for example, perpendicularly or approximately perpendicularly, to enhance the structural rigidity and torsional resistance of the second submodule 202. The vertical plate 2022 extends away from the platform surface and can be pre-set with mounting holes, slots, or threaded connection structures for connecting functional components (such as guardrails, mudguards, or electrical component mounting plates) on the frame 5. Through this structural design, the second submodule 202 not only bears the load-bearing function of the platform but also serves as a mounting base for functional components. This allows the load of the functional components to be directly transferred to the vertical plate 2022, and then transmitted to the frame 5 via the second submodule 202 and the fixing part 104. This avoids the need for additional holes or welded supports on the platform surface, thereby improving the overall integrity and structural strength of the platform. Meanwhile, the connection between the upright plate 2022 and the functional components further optimizes space utilization and enhances the multi-point fixation between the platform plate and the frame 5. It is particularly suitable for engineering machinery under high-frequency vibration or heavy-load conditions, and significantly improves the integration level and reliability of the whole vehicle.

[0063] In one embodiment, referring to Figures 3 to 5, the second sub-module 202 has a groove 2023 on the side opposite to the upright plate 2022. The groove 2023 extends along the opposite ends of the second sub-module 202 and is used to install functional components that are compatible with the walkway plate.

[0064] In this embodiment, the second submodule 202 is located at the edge of the frame 5, and a groove 20232023 extending along the opposite ends of the second submodule 202 is provided on the side facing away from the upright plate 2022. The groove is used to install the platform plate or functional components on the frame 5, making the structure more compact.

[0065] Specifically, the groove 2023 can be used to install reflective strips on the frame 5.

[0066] Furthermore, the second sub-module 202 is located at the edge of the frame 5, and the groove 2023 extends along the side edge of the frame 5. The L-shaped second module 2 cooperates with the first module 1 to form a semi-enclosed structure covering the frame 5. Through the semi-enclosed structure, there are multiple fixed points at various angles between the walkway and the frame 5, which makes the structure after the walkway and the frame 5 are combined have higher strength.

[0067] In one embodiment, referring to Figures 1 and 2, the first module 1 is further provided with a support member 105 on the side near the frame 5. The support member 105 extends in the direction near the frame 5 and abuts against the frame 5; and / or, the side of the walkway away from the fixing part 104 is provided with an anti-slip part 4 at least partially. The anti-slip part 4 is a plurality of protrusions extending in the direction away from the walkway.

[0068] In this embodiment, the support member 105 is a reinforcing rib structure located at the bottom of the first module 1. It protrudes from the body of the first module 1 toward the frame 5, forming continuous or spaced support protrusions. When the first module 1 is connected to the frame 5 via the fixing part 104, the end of the support member 105 abuts tightly against the surface of the frame 5, thereby forming an auxiliary support point between the first module 1 and the frame 5. Through this structural design, the support member 105 not only enhances the structural strength and bending stiffness of the first module 1 itself, but also directly transfers part of the load borne by the walkway to the frame 5, dispersing the force on the fixing part 104 and avoiding local stress concentration. At the same time, the abutting cooperation between the support member 105 and the frame 5 can effectively suppress the vibration and displacement generated by the walkway during equipment operation, improving the overall stability and fatigue resistance of the walkway.

[0069] In this embodiment, at least a portion of the side of the walkway away from the fixing part 104 is provided with an anti-slip part 4, which is a plurality of protrusions extending in the direction away from the walkway. Specifically, the anti-slip part 4 is disposed on the upper surface of the first module 1 or the first sub-module 201, i.e., the surface on which the operator walks and works, and is formed by extrusion molding or subsequent processing into an array of protrusions, dots, or stripes. These protrusions can effectively increase the coefficient of friction between the surface and the sole of the shoe, providing reliable anti-slip performance in rainy, oily, or muddy conditions, preventing the operator from slipping and falling, and significantly improving the safety of the walkway. At the same time, the protrusions of the anti-slip part 4 form natural drainage and mud removal channels, avoiding water or mud accumulation that reduces the anti-slip effect, and the protrusions are integrally formed with the walkway body, without the need for additional bonding or welding, ensuring the integrity and durability of the structure.

[0070] Furthermore, the support member 105 is not limited to being provided on the first module 1; the support member 105 can also be provided on the first sub-module 201 to increase the structural strength of the second module 2.

[0071] In one embodiment, the fixing part 104 has a receiving space, and at least a portion of the fixing part 104 is connected to the frame 5 by fasteners. The receiving space is used to accommodate the fasteners. The fixing part 104 is provided in at least two locations, and at least one location corresponds to the recess 103.

[0072] In this embodiment, the fixing part 104 has a receiving space, and at least a portion of the fixing part 104 is connected to the frame 5 by fasteners. This receiving space is used to accommodate fasteners. Specifically, the fixing part 104 can be configured as a slot structure extending along the length of the platform plate, with a receiving space inside to accommodate the head of a fastener such as a hexagonal head bolt. The size design of the slot prevents the bolt head from rotating, thereby achieving pre-installation and concealed fixing of the fastener. The fixing part 104 is provided in at least two places to ensure a reliable multi-point connection between the platform plate and the frame 5, avoiding loosening or displacement caused by single-point force. Among them, at least one fixing part 104 is correspondingly provided with the recessed part 103, that is, the fixing part 104 is positioned opposite to the recessed part 103 at one end of the first module 1, so that the installation position of the fastener forms a reasonable layout with the module splicing structure, which optimizes space utilization and enhances the connection strength at the splicing point. With this structural design, the fasteners are completely hidden inside the fixing part 104, preventing the bolts from being exposed on the walkway surface, eliminating the safety hazard of tripping pedestrians, and improving the overall aesthetics and refinement of the walkway.

[0073] Furthermore, the fixing part 104 can also be used for the arrangement and layout of wire harnesses. By adding a pipeline fixing clip, the clip can be inserted into the receiving space of the fixing part 104 to achieve the neat fixing of the wire harness and prevent the wire harness from hanging loosely under the platform or interfering with other components.

[0074] In one embodiment, the two ends of the fixing part 104 and the connecting part 2021 extend to two opposite edges of the module body 101, and at least one end is flush with the edge.

[0075] Specifically, the fixing part 104, serving as a slot structure on the first sub-module 201 connected to the frame 5, and the connecting part 2021, serving as a structure on the second sub-module 202 for lateral splicing of adjacent modules, are both designed to extend along the length direction, with their starting and ending ends aligned with the two end edges of the walkway plate along the length direction, respectively. Through this structural design, the fixing part 104 and the connecting part 2021 can cover the entire length of the walkway plate, ensuring that the installation positions of the fasteners and the lateral connections between modules are distributed at both ends of the walkway plate, thereby forming uniform force support along the length direction and avoiding localized stress concentration.

[0076] Furthermore, the two ends of the fixing part 104 and the connecting part 2021 are aligned with the ends of the walkway plate along its length. This arrangement facilitates standardized cutting and modular assembly of the walkway plate along its length. When the walkway plate needs to be cut or spliced ​​according to the actual length of the frame 5, the fixing part 104 and the connecting part 2021 can still maintain complete structural functions without additional processing, which significantly improves the manufacturing convenience and on-site adaptability of the walkway plate.

[0077] According to an embodiment of the present invention, in another aspect, an engineering machine is also provided, including the walkway mentioned in the first aspect.

[0078] In this embodiment, since the engineering machinery proposed in the second aspect includes the walkway of the first aspect, the engineering machinery has the same effect as the walkway. The specific technical effects of the walkway will not be described in detail here.

[0079] It should be noted that the term "and / or" as used in this specification is an associative description used to indicate one or more possible selection or combination relationships between the two or more listed items. Specifically, "and / or" includes the case where each of the listed items exists individually, as well as the case where any two or more items exist simultaneously, that is, it covers all possible subset combinations of the listed items, and does not exclude the possibility that other unlisted items may exist simultaneously with the combination.

[0080] For example, when expressed as "A and / or B," it should be understood to include the following three implementation schemes: only A exists, only B exists, and both A and B exist simultaneously. Here, A and B represent two different technical features, components, steps, or options. This expression aims to clarify that in the described technical solution, A and B can be either one or both, depending on the specific application scenario or design requirements.

[0081] When a statement refers to three or more items, such as "A, B, and / or C", it should be understood to include all possible combinations of the following: A alone, B alone, C alone, A and B simultaneously, A and C simultaneously, B and C simultaneously, and A, B, and C simultaneously. That is, "and / or" covers all possible combinations of any one or more of the listed items, and each combination is independent of the others and constitutes part of the technical solution disclosed in this specification.

[0082] The above definitions are intended to ensure that those skilled in the art can accurately understand the logical relationship expressed by "and / or" when reading this specification, and to avoid misinterpretation or limitation of the scope of protection of this invention due to ambiguity in language. The use of this term is to describe the various possibilities between technical features more concisely and clearly, rather than to impose exclusive restrictions on specific combinations.

[0083] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope defined by the appended claims.
