However, when using cantilever beams for installation, the problems of insufficient strength of large-area cover plate welded parts and low flatness of welding surface have always troubled the workers. At present, the existing solutions to this problem have certain defects.

[0026] Beneficial effects of the present invention:

By optimizing the specific structure of the cover plate welded part, the manufacturing process of the cover plate welded part can be simplified. The above improvement can ensure that the thickness of the cover plate welded part is directly related to the width of the first reinforcing rib and the second reinforcing rib, avoiding the unevenness of the cover plate welded part, and at the same time, it also has the advantages of light weight, beautiful appearance and reliable structural strength, and has broad application prospects and economic benefits.

[0028] The manufacturing method of the cover plate welded part firstly matches all the first reinforcing ribs with the second reinforcing ribs by mortise and tenon joints, then uses glue to bond them, then performs spot welding connection, and finally covers the upper plate and performs spot welding connection. The above manufacturing method improves the integrity and stability of the cover plate welded part, and at the same time reduces the error and deformation in the welding process, ensuring the overall stability and safety of the cover plate welded part. Among them, the design of bonding the first reinforcing ribs and the second reinforcing ribs to the upper plate surface of the lower plate with glue improves the integrity and connection strength of the cover plate welded part. The scheme of using glue bonding makes the first reinforcing ribs and the second reinforcing ribs fit closely with the lower plate, ensures the flatness, and facilitates the smooth progress of subsequent welding operations. Through spot welding connection, the connection stability between the various components of the cover plate welded part is further enhanced, and the manufacturing efficiency is also improved. The step of covering the upper plate is adopted to effectively complete the overall assembly of the cover plate welded part, making the structure more complete and firm. According to the above-mentioned step-by-step manufacturing steps, the precise positioning and stable connection of the various components of the cover plate welded part are achieved, ensuring the quality and precision of the cover plate welded part.

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] like Figure 1 and Figure 2 As shown, the present embodiment provides a cover plate welding member, including a lower plate 100 and an upper plate 200 arranged opposite to each other in a vertical direction Z, a plurality of first reinforcing ribs 300 evenly spaced along a first direction X and a plurality of second reinforcing ribs 400 evenly spaced along a second direction Y are provided between the lower plate 100 and the upper plate 200, and the first reinforcing ribs 300 extend along the second direction Y, and the second reinforcing ribs 400 extend along the first direction X, the top of the first reinforcing rib 300 and the top of the second reinforcing rib 400 are both fixedly connected to the lower plate surface of the upper plate 200, the bottom of the first reinforcing rib 300 and the bottom of the second reinforcing rib 400 are both fixedly connected to the upper plate surface of the lower plate 100, and each first reinforcing rib 300 is fixed with any second reinforcing rib 400 by mortise and tenon joints, wherein the first direction X is perpendicular to the vertical direction Z, and the second direction Y is perpendicular to the vertical direction Z.

[0046] The cover plate weldment realizes a stable connection between the lower plate 100 and the upper plate 200 which are arranged relatively in the vertical direction Z by setting the first reinforcing ribs 300 and the second reinforcing ribs 400. The tenon-and-mortise joints of the first reinforcing ribs 300 evenly spaced in the first direction X and the second reinforcing ribs 400 evenly spaced in the second direction Y enhance the anti-twisting and anti-stretching capabilities of the cover plate weldment in the first direction X and the second direction Y, making the cover plate weldment more stable and reliable when subjected to pressure and bending, thereby effectively improving the connection strength and impact resistance of the structure, and enhancing the stability, reliability and bearing capacity of the overall structure of the cover plate weldment. Moreover, the setting of the first reinforcing ribs 300 and the second reinforcing ribs 400 can enhance the stability and load-bearing capacity of the cover plate weldment in the vertical direction Z, effectively avoiding deformation or fracture of the cover plate weldment when subjected to external forces, thereby helping to extend the service life of the cover plate weldment. By optimizing the design of the specific structure of the cover plate weldment, the manufacturing process of the cover plate weldment can be simplified. The above improvement can ensure that the thickness of the cover plate weldment is directly related to the width of the first reinforcing rib 300 and the second reinforcing rib 400, avoiding the unevenness of the cover plate weldment. At the same time, it also has the advantages of light weight, beautiful appearance and reliable structural strength, and has broad application prospects and economic benefits.

[0047] In this embodiment, the top of the first reinforcing rib 300 is provided with a plurality of first mortise and tenon grooves 301 evenly spaced along the second direction Y, and the bottom of the second reinforcing rib 400 is provided with a plurality of second mortise and tenon grooves 401 evenly spaced along the first direction X, and the first mortise and tenon grooves 301 and the second mortise and tenon grooves 401 are inserted and matched.

[0048] Through the insertion and matching of the first mortise and tenon groove 301 designed at the top of the first reinforcing rib 300 and the second mortise and tenon groove 401 designed at the bottom of the second reinforcing rib 400, the precise positioning and stable connection between the reinforcing ribs are achieved, the connection stability between the first reinforcing rib 300 and the second reinforcing rib 400 is enhanced, and the overall structural stability and seismic performance of the cover plate weldment are improved. At the same time, the mortise and tenon fixing method between the first reinforcing rib 300 and the second reinforcing rib 400 not only improves the overall stability of the structure, but also simplifies the assembly process and improves production efficiency.

[0049] In one implementation of the present embodiment, the first reinforcing rib 300 and the second reinforcing rib 400 are spot-welded to each other; and the first reinforcing rib 300 and the second reinforcing rib 400 are spot-welded to the upper plate 200; and the first reinforcing rib 300 and the second reinforcing rib 400 are spot-welded to the lower plate 100.

[0050] The spot welding connection between the first reinforcing rib 300 and the second reinforcing rib 400, as well as the spot welding connection between them and the upper plate 200 and the lower plate 100, enhances the connection firmness between the components of the cover plate weldment, and ensures the overall structural strength. The above-mentioned multi-spot welding method achieves the purpose of reinforcement, improves welding efficiency, and enhances the structural integrity while ensuring the welding quality, making the cover plate weldment more firm, less prone to deformation or breakage, improving its reliability in use, and effectively preventing relative displacement that may occur during use. The spot welding connection between the first reinforcing rib 300 and the second reinforcing rib 400 and the upper plate 200 and the lower plate 100 enhances the overall stability of the cover plate weldment and reduces the risk of deformation.

[0051] In other implementations of this embodiment, the spot welding connection method is one or two of the above-mentioned schemes. The specific connection method is determined by the staff in this field according to the actual engineering practice. The determination method is common knowledge in this field and will not be elaborated here.

[0052] In this embodiment, the edge of the lower plate 100 is bent upward to form a flange 101 , and the flange 101 is welded to the edge of the upper plate 200 .

[0053] The flange 101 formed by the upward bending of the edge of the lower plate 100 is connected to the edge of the upper plate 200 by welding, which enhances the firmness of the edge of the cover plate weldment and improves the connection strength between the upper plate 200 and the lower plate 100. The above design also facilitates the installation and fixation of the cover plate weldment, improves its convenience and safety in use, and improves the stability of the overall structure. Moreover, the welding process of the flange 101 improves the overall aesthetics and durability of the cover plate weldment.

[0054] Exemplarily, an open hole 201 passes through the upper plate 200 .

[0055] The design of the open hole 201 through the upper plate 200 effectively reduces the weight of the cover plate weldment and helps to improve the overall rigidity. The above design reduces the material cost while maintaining the structural strength, and makes the cover plate weldment lighter. Without reducing the structural strength, the material utilization rate and the space utilization rate of the overall structure are improved. At the same time, it is also convenient for the welding gun to extend into the interior of the cover plate weldment for welding operations, which helps to reduce the manufacturing difficulty of the cover plate weldment.

[0056] In this embodiment, the first direction X is perpendicular to the second direction Y.

[0057] Through the vertical relationship between the first direction X and the second direction Y, the structural layout of the cover plate welded parts is more reasonable, and can provide uniform structural support in different directions, so that the force distribution of the cover plate welded parts in different directions is more balanced, and the comprehensive performance of the structure is improved. The above improvements also improve the adaptability of the cover plate welded parts in various usage scenarios, so that they have excellent strength and stability in both the first direction X and the second direction Y. The above structural design enables the cover plate welded parts to adapt to more usage scenarios, thereby improving their versatility and flexibility.

[0058] like Figures 1 to 3 As shown, this embodiment also provides a method for manufacturing a cover plate welding part, which is applied to the above-mentioned cover plate welding part, and includes the following steps:

[0059] Step 1: Fit all the first reinforcing ribs 300 and all the second reinforcing ribs 400 by mortise and tenon joints.

[0060] Step 2: Use glue to bond all the first reinforcing ribs 300 and all the second reinforcing ribs 400 to the upper surface of the lower plate 100 .

[0061] Step three: spot-weld the connection between the first reinforcing rib 300 and the second reinforcing rib 400 , spot-weld the contact position between the first reinforcing rib 300 and the lower plate 100 , and spot-weld the contact position between the second reinforcing rib 400 and the lower plate 100 .

[0062] Step 4: Cover the upper plate 200 on all the first reinforcing ribs 300 and all the second reinforcing ribs 400 .

[0063] Step 5: spot-weld the first reinforcing rib 300 to the contact position of the upper plate 200 , and spot-weld the second reinforcing rib 400 to the contact position of the upper plate 200 .

[0064] The manufacturing method of the cover plate welded parts firstly mortise and tenon all the first reinforcing ribs 300 and the second reinforcing ribs 400, then use glue to bond them, and then perform spot welding connection, and finally cover the upper plate 200 and perform spot welding connection, the above manufacturing method improves the integrity and stability of the cover plate welded parts, while reducing the error and deformation in the welding process, ensuring the overall stability and safety of the cover plate welded parts. Among them, the design of bonding the first reinforcing ribs 300 and the second reinforcing ribs 400 to the upper plate surface of the lower plate 100 with glue improves the integrity and connection strength of the cover plate welded parts. The scheme of using glue bonding makes the first reinforcing ribs 300 and the second reinforcing ribs 400 fit closely with the lower plate 100, ensuring the flatness and facilitating the smooth progress of subsequent welding operations. Through spot welding connection, the connection stability between the various components of the cover plate welded parts is further enhanced, and the manufacturing efficiency is also improved. The step of covering the upper plate 200 is adopted to effectively complete the overall assembly of the cover plate welded parts, making the structure more complete and firm. According to the above-mentioned step-by-step manufacturing steps, accurate positioning and firm connection of various components of the cover plate welded parts are achieved, ensuring the quality and precision of the cover plate welded parts.

[0065] Furthermore, the cover plate welding piece further includes a hinged fixing tube 500 disposed between the lower plate 100 and the upper plate 200, the top of the hinged fixing tube 500 being fixedly connected to the lower plate 100, and the bottom of the hinged fixing tube 500 being fixedly connected to the upper plate 200. Specifically, a lower avoidance hole 102 is formed through the lower plate 100, and the lower avoidance hole 102 is connected to the hinged fixing tube 500; an upper avoidance hole 202 is formed through the upper plate 200, and the upper avoidance hole 202 is connected to the hinged fixing tube 500.

[0066] The cover plate weldment is hingedly matched with the external component by setting the hinged fixing tube 500, thereby enhancing the structural stability and anti-torsion ability of the cover plate weldment. The top and bottom of the hinged fixing tube 500 are fixed to the lower plate 100 and the upper plate 200, so that the cover plate weldment can more stably withstand and disperse the force when subjected to external force, thereby improving the service life and safety of the cover plate weldment and enhancing the safety and stability of the cover plate weldment. At the same time, the top and bottom of the hinged fixing tube 500 are respectively fixed to the lower plate 100 and the upper plate 200, thereby improving the connection stability between the lower plate 100 and the upper plate 200, forming a more stable connection structure, so that the cover plate weldment can maintain good performance even in complex environments.

[0067] Specifically, this embodiment takes a cantilever beam-shaped cover device as an example, the above-mentioned hinged fixing tube 500 is used to be hinged with the rotation axis of the cantilever beam, and the cover plate welding parts are used to achieve the purpose of shielding.

[0068] In other implementations of this embodiment, the installation method of the hinged fixing tube 500 and the application purpose of the cover plate welding parts are determined by the staff in this field according to the actual engineering practice. The determination method is common knowledge in this field and will not be elaborated here.

[0069] Furthermore, one of all the first reinforcing ribs 300 and all the second reinforcing ribs 400 is defined as a connecting rib, which is fixed to the outer wall of the hinged fixed tube 500. The outer wall of the hinged fixed tube 500 is also fixed with two third reinforcing ribs 600 and one fourth reinforcing rib 700. The length direction of the third reinforcing rib 600 is perpendicular to the length direction of the connecting rib, and the length direction of the fourth reinforcing rib 700 is the same as the length direction of the connecting rib.

[0070] By fixing the third reinforcing rib 600 and the fourth reinforcing rib 700 to the outer wall of the hinged fixed tube 500, a stable frame is formed, which ensures the stability of the hinged fixed tube 500, improves the overall strength and stability of the cover plate weldment, and makes it more suitable for various complex working environments and load-bearing requirements. The design of the connecting rib fixed to the outer wall of the hinged fixed tube 500 can be combined with the reasonable arrangement of the third reinforcing rib 600 and the fourth reinforcing rib 700, thereby improving the complexity and load-bearing capacity of the structure, so that the cover plate weldment has good load-bearing capacity and impact resistance in different directions. By fixing a part of the first reinforcing rib 300 and the second reinforcing rib 400 to the outer wall of the hinged fixed tube 500, the connection strength between the hinged fixed tube 500 and the entire structure can be enhanced, thereby ensuring the structural rigidity of the entire cover plate weldment.

[0071] Furthermore, before step 4, the following steps are also included: placing the hinged fixed tube 500, two third reinforcing ribs 600 and one fourth reinforcing rib 700 on the lower flat plate 100. Fully welding the hinged fixed tube 500 to the contact position of the lower flat plate 100, fully welding the hinged fixed tube 500 to the contact position of the connecting rib, fully welding the hinged fixed tube 500 to the contact position of the third reinforcing rib 600, fully welding the hinged fixed tube 500 to the contact position of the fourth reinforcing rib 700, spot welding the third reinforcing rib 600 to the contact position of the lower flat plate 100, and spot welding the fourth reinforcing rib 700 to the contact position of the lower flat plate 100. After step 4, the following steps are also included: fully welding the hinged fixed tube 500 to the contact position of the upper flat plate 200, spot welding the third reinforcing rib 600 to the contact position of the upper flat plate 200, and spot welding the fourth reinforcing rib 700 to the contact position of the upper flat plate 200.

[0072] By adding welding steps for the hinged fixed tube 500 and the third and fourth reinforcing ribs 600 and 700 on the basis of the original manufacturing steps, the stable connection between these components and the lower plate 100 and the upper plate 200 is ensured. At the same time, the combined use of full welding connection and spot welding connection effectively ensures the connection quality and welding efficiency between the components, thereby further ensuring the overall safety and stability of the cover plate welded parts. The above design makes the manufacturing process more orderly and efficient through optimized manufacturing steps, reduces the error rate in the production process, and ensures the quality and precision of the cover plate welded parts. During the manufacturing process, the hinged fixed tube 500, the third and fourth reinforcing ribs 600 and 700 are first placed on the lower plate 100 for full welding connection and spot welding connection, and then the upper plate 200 is covered and corresponding welding and spot welding connections are performed. The above manufacturing method improves the uniformity and integrity of welding, reduces deformation and errors during welding, and ensures the quality and stability of the cover plate welded parts.

[0073] In this embodiment, the welding operation selects the method of hole welding, or uses a direct penetration welding scheme such as laser welding, resistance welding, etc. to ensure the strength of the welding.
