Description

Technical Field

[0001] The present invention relates to the field of ship loading locomotive tail cars, and in particular to a manufacturing method of a mobile ship loading locomotive tail car and the mobile ship loading locomotive tail car. Background Art

[0002] In the field of port logistics, mobile ship loaders are key equipment to ensure efficient loading of cargo. As one of its most important components, the tail truck is responsible for accurately transporting materials from the dock to the conveyor belt on the main ship loader. The quality of its performance directly affects the efficiency and stability of the entire loading operation.

[0003] The tail car structure is complex, primarily consisting of key components such as outriggers, crossbeams, a tail car platform, and a belt frame. Unlike conventional quay crane components, each tail car component has unique manufacturing requirements. The outriggers, serving as the tail car's supporting structure, require precision in manufacturing to directly impact the car's overall stability and safety. The crossbeams must possess sufficient strength to support the weight of the superstructure and the dynamic loads associated with material transfer. The tail car platform provides space for operator operation and maintenance, and precise control of its manufacturing dimensions is crucial. The belt frame ensures smooth belt operation and efficient material transfer.

[0004] However, traditional manufacturing methods have numerous drawbacks. The leg manufacturing process is cumbersome, resulting in long production cycles. The belt rack is difficult to manufacture, transport, and assemble, increasing manufacturing costs and time. The tail truck platform's dimensions are difficult to precisely control, impacting overall assembly quality. The tail truck's assembly height is too high, forcing workers to work at height, which not only makes construction difficult but also poses significant safety risks. Summary of the Invention

[0062] The following combination Figures 1 to 9 The manufacturing method of the mobile ship loading tail car 10 provided in this embodiment is described in detail.

[0063] Please refer to Figures 1 to 9 An embodiment of the present invention provides a method for manufacturing a mobile ship loading locomotive tail car 10, which is used to manufacture the mobile ship loading locomotive tail car 10. The method for manufacturing the mobile ship loading locomotive tail car 10 includes:

[0064] Step S1: Connect the support flange 110 to the leg connection flange 210 at the lower end of the leg 200 to meet the clearance requirements. Using the leg connection flange 210 surface as a reference plane, mark the trimming line of the upper end of the leg 200, the inner hole processing line of the support 100, and the heavy plate processing line of the support 100.

[0065] Step S2: The belt frame 500 is manufactured in a split modular manner, and the connection nodes between the belt frame 500 and the crossbeam 300 are disassembled into independent units, and the spatial position of the weld between the belt frame 500 and the crossbeam 300 is reconstructed;

[0066] Step S3: Preset a size compensation margin at the connection node joint position of the tail car platform 400 and the crossbeam 300, and weld a detachable temporary process support 600 at the joint gap between the tail car platform 400 and the crossbeam 300 to control the node assembly gap and gap size;

[0067] Step S4, assembling the belt frame 500, the tail car platform 400 and the crossbeam 300 on the low-altitude tire frame 700, and then hoisting the entire structure onto the support legs 200;

[0068] Step S5: Adjust the verticality of the support leg 200 through the anti-overturning support 800 and the wave and wind wire rope 900.

[0069] Among them, the mobile ship loader tail car 10 includes a connecting support 100, a support leg 200, a crossbeam 300, a tail car platform 400 and a belt frame 500. The connecting support 100 is connected to the lower end of the support leg 200, the upper end of the support leg 200 is fixed to the crossbeam 300, the tail car platform 400 is fixed to the crossbeam 300, and the belt frame 500 is fixed to the crossbeam 300.

[0070] Reference Figure 1 and Figure 8 The connecting support 100 is the key part that connects the tail car to the trolley (or other moving parts). The supporting legs 200 are the supporting structure of the tail car.

[0071] First, connect the connecting support flange 110 to the leg connecting flange 210, ensuring the required clearance between the connecting flanges 510. Using the surface of the leg connecting flange 210 as a reference, a line is drawn. This provides a precise basis for the subsequent machining of the upper end of the leg 200, the inner hole of the connecting support 100, and the weight plate, ensuring the machining accuracy and assembly position accuracy of each component. The belt frame 500 is manufactured using a split modular design, disassembling the connection nodes and reconstructing the spatial position of the welds. This reduces manufacturing difficulty and improves the quality and precision of each module. The connection between the tail car platform 400 and the crossbeam 300 is pre-sized to allow for compensation, and a temporary process brace 600 is welded to effectively control the assembly gap and gap size, ensuring connection stability. During assembly, the belt frame 500, tail car platform 400, and crossbeam 300 are assembled on a low-altitude tire stand 700 and hoisted onto the leg 200 as a whole, reducing the risk and difficulty of working at height. Finally, the verticality of the legs 200 is adjusted using anti-overturning supports 800 and wave and wind wire ropes 900 to ensure the overall structural stability of the tail car. This manufacturing method closely coordinates all steps, from component processing to overall assembly, improving manufacturing precision and efficiency, and ensuring the structural stability and operational reliability of the mobile ship loader tail car 10.

[0072] Reference Figure 2In this embodiment, step S1, connecting the support flange 110 to the leg connection flange 210 at the lower end of the leg 200 to meet the clearance requirements, and using the surface of the leg connection flange 210 as a reference plane, marking the trimming line of the upper end of the leg 200, the inner hole processing line of the support 100, and the heavy plate processing line of the support 100, includes the following steps:

[0073] Step S11: When cutting the upper end of the support leg 200, a trimming margin is reserved, and the thickness of the support leg connecting flange 210 is processed in place according to the size requirements;

[0074] Step S12, manufacturing the connecting support 100 and machining the connecting support flange 110 to the required thickness;

[0075] Step S13, matching and processing the bolt holes of the connecting support flange 110 and the supporting leg connecting flange 210, and bolting the connecting support flange 110 and the supporting leg connecting flange 210 to meet the clearance requirement;

[0076] Step S14, using the leg connection flange 210 surface as the reference plane, mark the upper end trimming line of the leg 200, the inner hole processing line of the connecting support 100 and the heavy plate processing line of the connecting support 100, and make matching marks on the leg connection flange 210.

[0077] During the manufacturing process, the connecting bracket 100 must first be fabricated as an assembly. Its flange 510 (connecting bracket flange 110) must be machined to allow for adequate thickness to ensure proper clearance and bolt installation when connected to the leg connecting flange 210. The connecting bracket 100 and the leg 200 are manufactured together using the connecting bracket flange 110 and the leg connecting flange 210. Pairing marks are placed on the leg connecting flange 210 to facilitate subsequent installation and adjustment.

[0078] Leg 200, the supporting structure of the tail truck, requires a trimming allowance at its upper end when cutting. A thickness allowance must also be provided for leg connection flange 210 when cutting. Leg connection flange 210 is machined to allow for thickness, and bolt holes are machined for connection to support flange 110. Bolts are tightened to ensure clearance. Leg connection flange 210 serves as a marking reference for uniformly marking the trimming allowance for the upper edge of leg 200, as well as the machining allowance for the holes in support 100 and the weight plate.

[0079] Specifically, a trimming margin is reserved for the upper end of the leg 200 to provide adjustment space for subsequent precise trimming. The thickness of the leg connection flange 210 is processed in advance to ensure the accuracy of the basic dimensions. The connecting support 100 is made and the thickness of its flange 510 is processed to ensure the accuracy of the connecting support 100 itself. The bolt holes of the connecting support flange 110 and the leg connection flange 210 are matched and processed so that they can be precisely docked when bolted together to meet the clearance requirements, ensure the tightness and stability of the connection, and avoid affecting the structural strength and operational stability due to excessive or insufficient clearance. The surface of the leg connection flange 210 is used as the reference plane for marking, providing an accurate basis for trimming the upper end of the leg 200, the inner hole of the connecting support 100, and the processing of the heavy plate, ensuring that the processing position of each component is accurate and the size is compliant. Pairing marks are made on the leg connection flange 210 to facilitate quick and accurate docking during subsequent assembly, thereby improving assembly efficiency. This series of process steps, from component pre-treatment to precise marking, are closely linked, effectively improving manufacturing accuracy and ensuring that the components of the tail car structure are firmly connected and accurately positioned, laying a solid foundation for the overall quality and reliable operation of the mobile ship loader tail car 10.

[0080] Reference Figure 2 In this embodiment, step S15, after the support leg 200 is separated from the connecting support 100, the inner hole of the connecting support 100, the heavy plate margin of the connecting support 100 and the upper end margin of the support leg 200 are processed according to the upper end cutting line of the support leg 200, the inner hole processing line of the connecting support 100 and the heavy plate processing line of the connecting support 100, and the welding groove is prefabricated.

[0081] After the support leg 200 is separated from the connecting support 100, the remaining material is machined according to the markings and a pre-groove is formed. This process precisely removes excess material and ensures dimensional accuracy. The pre-groove provides good conditions for subsequent welding, improving weld quality and ensuring a secure connection and structural reliability between the support leg 200 and the connecting support 100.

[0082] Reference Figure 3 In this embodiment, step S2, the belt frame 500 is manufactured in a split modular manner, and the connection node between the belt frame 500 and the beam 300 is disassembled into independent units. The steps of reconstructing the spatial position of the weld between the belt frame 500 and the beam 300 include:

[0083] Step S21, the belt frame 500 is divided into two independent submodules, component 1 and component 2;

[0084] Step S22, the flange 510 and the roller assembly 520 connecting the belt frame 500 and the beam 300 are separated from the belt frame 500;

[0085] Step S23 , reconstructing the connection weld between the belt frame 500 and the crossbeam 300 from overhead welding to flat welding.

[0086] The belt frame 500, a component on the tail car used to convey materials, has a complex structure and multiple connection points with the crossbeam 300. To facilitate manufacturing, transportation, and assembly, the belt frame 500 is manufactured in two parts (Component 1 and Component 2). The flange 510 and roller assembly 520, which connect to the crossbeam 300, are manufactured separately from the belt frame 500.

[0087] The crossbeam 300 is a key component connecting the legs 200, the tail car platform 400, and the belt frame 500. The connection points between the belt frame 500 and the crossbeam 300 are diverse, making welding difficult. Therefore, reasonable methods and measures are required to adjust the connection points during the production phase. For example, the production method of the flange 510 and the roller assembly 520 at the connection point with the belt frame 500 is optimized, and the weld type is optimized from overhead welding to flat welding.

[0088] Specifically, the belt frame 500 is first manufactured using a split modular system, split into two independent submodules: Component 1 and Component 2. This approach facilitates fine-tuning of each submodule within a limited space, effectively controlling the dimensional accuracy and manufacturing quality of each module, and reducing overall manufacturing complexity. Next, the flange 510 and roller assembly 520, which connect the belt frame 500 to the crossbeam 300, are manufactured separately. This allows for independent optimization of process parameters for each component, improving manufacturing efficiency and component performance while avoiding potential interference from integrated manufacturing. Finally, the weld connecting the belt frame 500 and crossbeam 300 is restructured from overhead welding to flat welding. Overhead welding is difficult and difficult to ensure quality, while flat welding provides the welder with better visibility and ease of operation, enabling better control of welding parameters, ensuring weld quality, and reducing weld defects. This series of structural process modifications, from component fabrication to weld reconstruction, not only reduces manufacturing complexity and improves production efficiency, but also significantly improves the weld quality at the connection between the belt frame 500 and crossbeam 300, enhancing the stability and reliability of the overall structure.

[0089] Reference Figure 3 In this embodiment, the connecting flange 510 and the roller assembly 520 are reassembled by positioning tooling when the belt frame 500 is assembled as a whole.

[0090] During the overall assembly of the belt frame 500, the connecting flange 510 and the roller assembly 520 are reassembled using a positioning fixture. This fixture precisely locates the two, ensuring installation accuracy and avoiding deviations caused by manual installation. This ensures that all components are tightly connected and accurately positioned, improving assembly efficiency and quality, and ensuring stable operation of the belt frame 500.

[0091] Reference Figure 4In this embodiment, step S3, presetting a dimension compensation margin at the connection node joint position of the tail car platform 400 and the crossbeam 300, and welding a detachable temporary process support 600 at the joint gap between the tail car platform 400 and the crossbeam 300 to control the node assembly gap and the gap size, includes the following steps:

[0092] Step S31, presetting an adjustment margin at a node joint position;

[0093] Step S32, welding a detachable temporary process support 600 at the joint opening;

[0094] Step S33, controlling the assembly gap by adjusting the allowance, and constraining the opening size by using the temporary process support 600.

[0095] The tail car platform 400 is the work area on the tail car. It connects to the crossbeam 300 through numerous joints and requires high welding accuracy. During fabrication, allowances for joint adjustments must be reserved, and temporary support braces 600 are added at the joint openings to ensure proper installation clearance and opening dimensions, minimizing adjustment work and welding deformation.

[0096] First, a preset adjustment margin is added to the joint connecting the tail platform 400 and the crossbeam 300. This provides flexible adjustment space for subsequent installation, accounting for dimensional deviations that may occur during the manufacturing process and ensuring a tight connection. Next, a removable temporary process brace 600 is welded to the joint opening. This brace provides rigid support and effectively constrains the opening dimensions during assembly, preventing structural deformation due to external forces or weight, and ensuring that the opening dimensions meet design requirements. During assembly, the preset adjustment margin allows for precise control of the node assembly gap, ensuring precise alignment of components and avoiding excessive gaps that affect structural strength or insufficient gaps that hinder assembly. While constraining the opening dimensions, the temporary process brace 600 also provides stable structural support throughout the assembly process, improving assembly precision and efficiency. Once assembly is complete and the structure is stable, the temporary process brace 600 is removed without affecting the final structural performance. Through this series of processes, the assembly quality of the joint connecting the tail platform 400 and the crossbeam 300 is precisely controlled, ensuring the stability and reliability of the overall structure.

[0097] Reference Figure 5 In this embodiment, step S4, assembling the belt frame 500, the tail car platform 400 and the crossbeam 300 on the low-altitude tire frame 700, and then hoisting the entirety of the belt frame 500 onto the support legs 200, includes:

[0098] Step S41, assembling the belt frame 500, the tail car platform 400 and the crossbeam 300 on the low-altitude tire frame 700;

[0099] Step S42, after the auxiliary structure is installed in place, it is hoisted as a whole to the support leg 200;

[0100] Among them, the auxiliary structure includes the belt rack 500 accessories, the tail car platform 400 guardrail and the crossbeam 300 walkway.

[0101] The belt frame 500, the tail car platform 400 and the crossbeam 300 are assembled on the low-altitude tire frame 700, and the various auxiliary structures are installed in place at a low altitude, and then installed as a whole on the support legs 200 to reduce high-altitude construction and safety risks.

[0102] Specifically, the assembly of the belt frame 500, the tail car platform 400 and the crossbeam 300 is carried out before the low-altitude tire frame 700. The low-altitude tire frame 700 provides a stable and precise working platform for assembly, which can ensure that the positions of the components are accurate and the connections are firm during the assembly process, effectively reducing the safety risks and operational difficulties brought by high-altitude operations, and improving the assembly efficiency and quality. During the assembly process, the relative positions of the components can be easily adjusted and calibrated to ensure that the geometric dimensions of the overall structure meet the design requirements. After the main structure is assembled, the auxiliary structures such as the belt frame 500 accessories, the tail car platform 400 guardrails and the crossbeam 300 walkway are installed in place. These auxiliary structures not only improve the function of the equipment, but also enhance the safety and stability of the overall structure. After that, the overall hoisting operation to the support leg 200 is carried out. The overall hoisting avoids the tediousness and error accumulation of multiple high-altitude docking, and ensures the connection accuracy between the components and the integrity of the overall structure. By adopting this process of first assembling at low altitude, installing the auxiliary structures and then hoisting the entire structure, the manufacturing accuracy is effectively improved, the construction safety is guaranteed, and the structure of the mobile ship loader tail car 10 is made more stable and reliable.

[0103] Reference Figure 6 and Figure 7 In this embodiment, step S5, the step of adjusting the verticality of the support leg 200 by using the anti-overturning support 800 and the wave and wind wire rope 900 includes:

[0104] Step S51, welding the anti-overturning support 800 ear plate and the wave and wind lifting ear at the preset position of the support leg 200;

[0105] Step S52: hoist the support leg 200 to the installation position, detachably connect the anti-overturning support 800 to the support ear plate, and connect the wave and wind wire rope 900 to the wave and wind lifting ear;

[0106] Step S53: Adjust the verticality of the support leg 200 through the anti-overturning support 800 and the wave and wind wire rope 900.

[0107] During final assembly, the anti-overturning support 800 ear plates and the wave and wind lifting ears are installed on the support legs 200. By installing the anti-overturning support 800 and the wave and wind wire rope 900, the support legs 200 are effectively adjusted to ensure the accuracy of the installation of the tail car superstructure.

[0108] First, weld the anti-overturning support 800 ear plate and the Langfeng lifting ear at the preset position of the leg 200. This builds a key connection point for the subsequent adjustment of the verticality and ensures that the adjustment device can be installed firmly. Then, after the leg 200 is hoisted to the installation position, the anti-overturning support 800 is detachably connected to the support ear plate, and the Langfeng wire rope 900 is connected to the Langfeng lifting ear to form a complete verticality adjustment system. The anti-overturning support 800 provides a stable support force to prevent the leg 200 from overturning during the adjustment process; the Langfeng wire rope 900 applies force to the leg 200 from different directions by tightening or loosening. Through the coordinated cooperation of the two, the position of the leg 200 can be accurately fine-tuned, and the verticality of the leg 200 can be effectively controlled to meet the design requirements. The precise adjustment of the verticality of the leg 200 is achieved, ensuring the stability and safety of the overall structure of the mobile ship loader tail car 10.

[0109] In this embodiment, step S53, the step of adjusting the verticality of the support leg 200 by using the anti-overturning support 800 and the wave and wind wire rope 900 includes:

[0110] Step S531, adjusting the angle ruler accuracy of the support leg 200 by adjusting the tension of the wave and wind wire rope 900 and the length of the anti-overturning support 800.

[0111] Adjusting the tension of the wave and wind wire rope 900 changes the direction and magnitude of the pull on the outrigger 200; adjusting the length of the anti-overturning support 800 changes the position of the support's action point. These two functions work together to exert force on the outrigger 200 from different dimensions, precisely adjusting the angle of the outrigger 200 to ensure that the outrigger 200 meets the required verticality and maintains structural stability.

[0112] The embodiment of the present invention further provides a mobile ship loading tail car 10. The mobile ship loading tail car 10 is manufactured by a mobile ship loading tail car 10 manufacturing method.

[0113] The mobile ship loader tail car 10 is built using a specific manufacturing method, featuring a rationally arranged structural structure and precise welding and assembly. This improves existing tail car manufacturing processes, which include long manufacturing processes, difficult assembly, difficult dimensional control, and high-altitude operation risks.

[0114] According to a manufacturing method of a mobile ship loader tail car 10 provided in this embodiment, the working principle of the manufacturing method of the mobile ship loader tail car 10 includes: in order to effectively shorten the manufacturing process of the tail car support legs 200, facilitate the production, transportation and assembly of the belt frame 500, accurately control the manufacturing size of the tail car platform 400, reduce the assembly height of the tail car, avoid high-altitude operations, reduce safety risks, and improve the integrity of the components, based on the principles of safety, convenience and efficiency, a new manufacturing method of the mobile ship loader tail car 10 is designed.

[0115] The main manufacturing processes include:

[0116] Reference Figure 1 and Figure 2 In order to ensure the gap between the connecting flanges 510 and the smooth installation of the bolts. When cutting the upper end of the support leg 200, it is necessary to reserve a trimming allowance. When cutting the connecting flange 510, a thickness allowance is reserved. The thickness allowance of the connecting flange 510 on the support leg 200 is directly processed in place. According to the required dimensions of the drawing, the connecting support 100 is first made into an assembly, and then the thickness of the connecting support flange 110 is processed to the required position. Then, the bolt holes on the two connecting flanges 510 are processed and tightened with bolts to ensure that the gap between the connecting flanges 510 meets the requirements. Finally, it is paired with the support leg 200 and produced. The surface of the support leg connecting flange 210 is designed as the marking reference, and the upper cutting allowance of the support leg 200 and the processing allowance of the connecting support 100 hole and the heavy plate are uniformly marked. Matching marks are made at the position of the connecting flange 510, and then the connecting support 100 is removed. The inner hole and heavy plate allowance of the connecting support 100 and the allowance of the upper end of the support leg 200 are processed according to the marked dimensions and the required dimensions of the drawing, and the groove is prefabricated in place.

[0117] Reference Figure 3 In order to facilitate the production, transportation and assembly of the belt rack 500, reduce the large amount of adjustment work during the assembly of the belt rack 500 and reduce the difficulty of welding. The structural form of the belt rack 500 is analyzed. First, the belt rack 500 is divided into two parts (component one and component two). Secondly, the connection node between the belt rack 500 and the crossbeam 300 is optimized. The flange 510 and the roller assembly 520 at the connection position are manufactured separately from the belt rack 500 to facilitate the subsequent assembly of the belt rack 500. The weld form at the connection between the belt rack 500 and the crossbeam 300 is optimized from overhead welding to flat welding.

[0118] Reference Figure 4 The tail car platform 400 and the crossbeam 300 have many connection nodes and high welding requirements. The assembly clearance control of the node joint position and the size of the opening at the node joint position will generate a large number of adjustment operations and large welding deformation. During production, adjustment margins are reserved in advance at the node joint position, and temporary process supports 600 are added at the joint opening position to ensure the installation clearance and opening size at the node position. When the tail car platform 400 and the crossbeam 300 are assembled, a large number of adjustment operations are reduced, welding deformation is reduced, and the overall quality of the tail car is improved.

[0119] Reference Figure 5 In order to facilitate construction, reduce high-altitude construction, reduce the frequency of use of flow machines, reduce safety risks, and improve the integrity of components, the belt frame 500, tail car platform 400 and beam 300 are assembled on the low-altitude tire frame 700, and each auxiliary structure is installed in place at a low altitude, and then installed as a whole on the support leg 200.

[0120] Reference Figure 6 and Figure 7 To control the size of the outrigger 200 and facilitate smooth installation of the tail car's upper components, anti-overturning support 800 lugs and Langfeng lifting lugs are installed on the outrigger 200. During final assembly, after the outrigger 200 is hoisted into place, the anti-overturning support 800 and Langfeng wire rope 900 are installed to effectively adjust the outrigger 200, ensuring the accuracy of the tail car's upper structure installation and improving the overall quality of the project.

[0121] The manufacturing method of the mobile ship loading tail car 10 provided in this embodiment has at least the following advantages:

[0122] In order to ensure the gap between the connecting flanges 510 and control the welding deformation of the flanges 510, the support leg 200 and the trolley connecting support 100 are required to be manufactured together, and the support leg connecting flange 210 is set as the marking reference to facilitate the unified marking of the upper cutting allowance of the support leg 200, as well as the processing allowance of the connecting support 100 hole and the heavy plate, thereby reducing manufacturing errors and improving the quality of the components.

[0123] To address the diverse connection points and welding difficulties between the belt frame 500 and the crossbeam 300, the belt frame 500 was rationally segmented, and the connection points with the crossbeam 300 were optimized. The flange 510 and roller assembly 520 at the connection points were manufactured separately from the belt frame 500, and the overhead welding was optimized to a flat welding method. This facilitates the production, transportation, and assembly of the belt frame 500, reduces adjustments during assembly, reduces welding difficulty, and improves production efficiency.

[0124] The tail car platform 400 and the crossbeam 300 have many connection nodes and high welding requirements. The clearance control and opening size of the node joint position will produce a large number of adjustment operations and large welding deformation. During production, the node joint position is pre-reserved with adjustment margins and temporary process supports 600 are added to the joint position opening to ensure the installation clearance and opening size of the node position.

[0125] In order to facilitate construction, reduce high-altitude construction, lower safety risks, and improve the integrity of components, the belt frame 500, tail car platform 400 and beam 300 are assembled on the low-altitude tire frame 700 and then installed as a whole on the support leg 200.

[0126] During final assembly, to control the dimensions of the outriggers 200 and ensure smooth installation of the tail car's upper components, anti-overturning support 800 lugs and wind and wave lifting lugs are installed on the outriggers 200. During final assembly, the installation of anti-overturning supports 800 and wind and wave wire ropes 900 effectively adjust the outriggers 200, ensuring accurate installation of the tail car's upper structure, improving the overall quality of the project, and enabling the mobile ship loader's tail car 10 to be put into operation.

[0127] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technology in this field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
