Description

Technical Field

[0001] This invention relates to the field of ship loader tail cars, and more specifically, to a method for manufacturing a mobile ship loader tail car. Background Technology

[0002] In the port logistics sector, mobile ship loaders are key equipment for ensuring efficient loading of goods onto ships. The tail car, as one of its most important components, undertakes the crucial task of accurately transferring dock materials to the conveyor belt on the main body of the ship loader. Its performance directly affects the efficiency and stability of the entire loading operation.

[0003] The tail car has a complex structure, mainly composed of key components such as outriggers, crossbeams, the tail car platform, and the conveyor belt frame. Unlike conventional quay crane components, each component of the tail car has unique requirements during manufacturing. The outriggers, as the supporting structure of the tail car, have manufacturing precision that directly affects the overall stability and safety of the tail car; the crossbeams need sufficient strength to bear the weight of the superstructure and the dynamic loads during material transport; the tail car platform provides space for operation and maintenance, and precise control of its manufacturing dimensions is crucial; the conveyor belt frame must ensure smooth belt operation and efficient material transport.

[0004] However, traditional manufacturing methods have many drawbacks. The outrigger manufacturing process is cumbersome, resulting in a long production cycle; the fabrication, transportation, and assembly of the conveyor belt frame are difficult, increasing manufacturing costs and time; the manufacturing dimensions of the tail car platform are difficult to control precisely, affecting the overall assembly quality; and the excessive height of the tail car assembly forces workers to perform high-altitude operations, which not only increases construction difficulty but also poses extremely high safety risks.

[0015] Optionally, the step of adjusting the verticality of the outriggers using anti-overturning supports and wave-resistant wire ropes includes: Weld anti-tipping support plates and wave-lift lugs at the preset positions of the outriggers; Hoist the outriggers to the installation position, detachably connect the anti-tipping brace to the support lug, and connect the wave wind steel wire rope to the wave wind lifting lug; The verticality of the outriggers is adjusted by using anti-tipping supports and wave-force steel wire ropes.

[0016] Optionally, the step of adjusting the verticality of the outriggers using anti-overturning supports and wave-resistant steel wire ropes includes: The accuracy of the outrigger angle gauge is adjusted by regulating the tension of the wave-wind steel wire rope and the length of the anti-overturning support.

[0028] The following is combined with Figures 1 to 9 The manufacturing method of the mobile ship loader tail car 10 provided in this embodiment will be described in detail.

[0029] Please refer to Figures 1 to 9 The present invention provides a method for manufacturing a mobile ship loader stern car 10, which is used to manufacture the mobile ship loader stern car 10. The method for manufacturing the mobile ship loader stern car 10 includes: Step S1: Connect the connecting support flange 110 to the lower end of the support leg 200 with the support leg connecting flange 210 to meet the clearance requirements. Using the support leg connecting flange 210 as the reference plane, draw the upper end trimming line of the support leg 200, the inner hole machining line of the connecting support 100, and the heavy plate machining line of the connecting support 100. Step S2: The belt conveyor frame 500 is manufactured using a modular split design, and the connection node between the belt conveyor frame 500 and the crossbeam 300 is disassembled into independent units, thus reconstructing the weld space position between the belt conveyor frame 500 and the crossbeam 300. Step S3: Preset a size compensation allowance at the joint of the connection node between the tail platform 400 and the crossbeam 300, and weld a detachable temporary process support 600 at the joint opening between the tail platform 400 and the crossbeam 300 to control the node assembly gap and opening size. Step S4: Assemble the belt conveyor frame 500, tail car platform 400 and crossbeam 300 on the low-altitude tire frame 700, and then hoist the whole assembly onto the outrigger 200. Step S5: Adjust the verticality of the outrigger 200 using the anti-overturning support 800 and the wave-wind steel wire rope 900.

[0030] The mobile ship loader tail car 10 includes a connecting support 100, outriggers 200, crossbeams 300, tail car platform 400, and belt conveyor frame 500. The connecting support 100 is connected to the lower end of the outriggers 200, the upper end of the outriggers 200 is fixed to the crossbeams 300, the tail car platform 400 is fixed to the crossbeams 300, and the belt conveyor frame 500 is fixed to the crossbeams 300.

[0031] Reference Figure 1 and Figure 8The connecting support 100 is a key component connecting the tail car to the trolley (or other moving parts). The outrigger 200 is the supporting structure for the tail car.

[0032] First, the connecting support flange 110 is connected to the outrigger connecting flange 210, ensuring that the gap between the connecting flanges 510 meets the requirements. Using the outrigger connecting flange 210 as a reference, lines are drawn to provide a precise basis for the subsequent processing of the upper end of the outrigger 200, the inner hole of the connecting support 100, and the weight plate, ensuring the processing accuracy and assembly position accuracy of each component. The conveyor frame 500 adopts a split modular manufacturing method, disassembling the connecting nodes and reconstructing the weld space position, reducing manufacturing difficulty and improving the manufacturing quality and precision of each module. The connection node between the tail platform 400 and the crossbeam 300 has a preset dimensional compensation allowance, and temporary process supports 600 are welded to effectively control the assembly gap and opening size, ensuring connection stability. During assembly, the conveyor frame 500, tail platform 400, and crossbeam 300 are assembled on the low-altitude jig 700 and then hoisted as a whole to the outrigger 200, reducing the risk and difficulty of high-altitude operations. Finally, the verticality of the outriggers 200 is adjusted using the anti-tipping supports 800 and the wave-force steel wire ropes 900 to ensure the overall structural stability of the tail car. This manufacturing method, from component processing to overall assembly, involves close coordination at each stage, improving manufacturing precision and efficiency, and ensuring the structural stability and operational reliability of the mobile ship loader tail car 10.

[0033] Reference Figure 2 In this embodiment, step S1, connecting the connecting support flange 110 to the lower end of the support leg 200 with the support leg connecting flange 210 to meet the clearance requirements, and using the surface of the support leg connecting flange 210 as the reference surface, the steps of drawing the upper end trimming line of the support leg 200, the inner hole machining line of the connecting support 100, and the heavy-duty plate machining line of the connecting support 100 include: In step S11, when cutting the upper end of the support leg 200, allowance is reserved for trimming, and the thickness of the support leg connecting flange 210 is processed to the required size. Step S12: Fabricate the connecting support 100 and machine the thickness of the connecting support flange 110 to the required level; Step S13: Pair the bolt holes of the connecting support flange 110 and the leg connecting flange 210, and bolt the connecting support flange 110 and the leg connecting flange 210 together to meet the clearance requirements. Step S14: Using the support flange 210 as the reference plane, draw the upper end trimming line of the support 200, the inner hole machining line of the connecting support 100, and the heavy plate machining line of the connecting support 100, and make matching marks on the support flange 210.

[0034] During the manufacturing process, the connecting support 100 needs to be fabricated as a component first. The thickness of its flange 510 (connecting support flange 110) needs to be pre-machined to ensure the clearance and accuracy of bolt installation when connected to the leg connecting flange 210. The connecting support 100 and the leg 200 are manufactured together using the connecting support flange 110 and the leg connecting flange 210, and a matching mark is made at the leg connecting flange 210 position for subsequent installation and adjustment.

[0035] Outrigger 200 is the supporting structure for the tail section. A trimming allowance must be allowed when cutting its upper end, and a thickness allowance must also be allowed when cutting the outrigger connecting flange 210. The thickness allowance of the outrigger connecting flange 210 is directly machined to the required depth, and bolt holes are machined to align with the connecting support flange 110. Bolts are then tightened to ensure proper clearance. The outrigger connecting flange 210 serves as a marking reference, used to uniformly mark the trimming allowance at the top of outrigger 200, as well as the machining allowance for the holes in the connecting support 100 and the weighing plate.

[0036] Specifically, the upper end of the outrigger 200 is pre-cut with a trimming allowance to provide adjustment space for subsequent precise trimming. The thickness of the outrigger connecting flange 210 is pre-processed to ensure accurate foundation dimensions. The connecting support 100 is fabricated, and its flange thickness 510 is machined to ensure the precision of the connecting support 100 itself. The bolt holes of the connecting support flange 110 and the outrigger connecting flange 210 are machined to ensure precise alignment during bolt connection, meeting clearance requirements and ensuring tightness and stability of the connection, avoiding impacts on structural strength and operational stability due to excessive or insufficient clearance. Lines are drawn using the surface of the outrigger connecting flange 210 as a reference plane to provide precise reference for trimming the upper end of the outrigger 200, machining the inner hole of the connecting support 100, and processing the weight plate, ensuring accurate positioning and dimensional compliance of each component. Matching marks are made on the outrigger connecting flange 210 to facilitate quick and accurate alignment during subsequent assembly, improving assembly efficiency. This series of processes, from component pretreatment to precise marking, are interconnected and effectively improve manufacturing precision, ensuring that the various 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.

[0037] Reference Figure 2 In this embodiment, in step S15, after the support leg 200 is separated from the connecting support 100, the inner hole of the connecting support 100, the excess of the weight plate of the connecting support 100 and the excess of the upper end of the support leg 200 are processed according to the upper end trimming line of the support leg 200, the inner hole processing line of the connecting support 100 and the weight plate processing line of the connecting support 100, and the welding bevel is prefabricated.

[0038] After the outrigger 200 is separated from the connecting support 100, the excess material in each part is machined according to the marking lines and the bevel is prefabricated. This process precisely removes excess material, ensures dimensional accuracy, and the prefabricated bevel provides good conditions for subsequent welding, improves welding quality, and ensures that the connection between the outrigger 200 and the connecting support 100 is stable and the structure is reliable.

[0039] Reference Figure 3 In this embodiment, step S2, which involves manufacturing the belt conveyor frame 500 using a modular design and disassembling the connection node between the belt conveyor frame 500 and the crossbeam 300 into independent units, and reconstructing the weld space position between the belt conveyor frame 500 and the crossbeam 300, includes: Step S21: Divide the belt conveyor frame 500 into two independent sub-modules, Component 1 and Component 2, and manufacture them. Step S22: Separate the flange 510 and roller assembly 520 connecting the belt conveyor frame 500 and the crossbeam 300 from the belt conveyor frame 500 for fabrication. Step S23: The connection weld between the belt conveyor frame 500 and the crossbeam 300 is changed from overhead welding to flat welding.

[0040] The belt conveyor frame 500 is a component on the tail car used for conveying materials. Its structure is complex and has various connection points with the crossbeam 300. To facilitate manufacturing, transportation and assembly, the belt conveyor frame 500 is manufactured in two parts (component one and component two), and the flange 510 and roller assembly 520 that connect with the crossbeam 300 are manufactured separately from the belt conveyor frame 500.

[0041] The crossbeam 300 is a crucial component connecting the outriggers 200, the tail platform 400, and the conveyor belt frame 500. The connection points between the conveyor belt frame 500 and the crossbeam 300 are diverse and challenging to weld. Therefore, during the manufacturing phase, appropriate methods and measures must be adopted to adjust the connection positions. For example, the manufacturing methods of the flange 510 and roller assembly 520 with the conveyor belt frame 500 can be optimized, and the weld type can be changed from overhead welding to flat welding.

[0042] Specifically, the conveyor frame 500 is first manufactured using a modular, split-type construction, divided into two independent sub-modules: Component One and Component Two. This approach facilitates precise machining of each sub-module 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 connecting the conveyor frame 500 and the crossbeam 300 are manufactured separately, allowing for independent optimization of process parameters for each component, improving manufacturing efficiency and component performance, and avoiding potential interference from overall manufacturing. Finally, the weld connecting the conveyor frame 500 and the crossbeam 300 is redesigned from overhead welding to flat welding. Overhead welding is more difficult and its quality is harder to guarantee, while flat welding offers better visibility and easier operation for the welder, allowing for better control of welding parameters, ensuring weld quality, and reducing welding defects. Through this series of structural and technological processes, from component manufacturing to weld redesign, not only is manufacturing difficulty reduced and production efficiency improved, but the welding quality at the connection between the conveyor frame 500 and the crossbeam 300 is also significantly enhanced, strengthening the overall structural stability and reliability.

[0043] Reference Figure 3 In this embodiment, the connecting flange 510 and the roller assembly 520 are reassembled by positioning fixtures during the overall assembly of the belt conveyor frame 500.

[0044] During the overall assembly of the belt conveyor frame 500, a positioning fixture is used to reassemble the connecting flange 510 and the roller assembly 520. The positioning fixture can accurately determine the position of the two, ensure installation accuracy, avoid deviations caused by manual installation, make the connections of each component tight and the positions accurate, improve assembly efficiency and quality, and ensure the stable operation of the belt conveyor frame 500.

[0045] Reference Figure 4 In this embodiment, step S3, which involves pre-setting a dimensional compensation allowance at the joint position of the connection node between the tail platform 400 and the crossbeam 300, and welding a detachable temporary process support 600 at the joint opening between the tail platform 400 and the crossbeam 300 to control the node assembly gap and opening size, includes the following steps: Step S31: Set an adjustment allowance at the node joint position; Step S32: Weld a detachable temporary process support 600 at the joint opening. Step S33: Control the assembly gap by adjusting the allowance, and constrain the opening size by using a temporary process support 600.

[0046] The tail car platform 400 is the working area on the tail car, with many connection nodes to the crossbeam 300 and high welding requirements. During fabrication, adjustment allowances need to be reserved at the node joint positions in advance, and temporary process supports 600 are added at the joint opening positions to ensure the installation gap and opening size at the node positions, and reduce adjustment work and welding deformation.

[0047] First, an adjustment allowance is preset at the joint position of the connection node between the tail platform 400 and the crossbeam 300, providing flexible adjustment space for subsequent installation and accommodating potential dimensional deviations during manufacturing to ensure a tight connection. Next, a detachable temporary process support 600 is welded at the joint opening. This support provides rigid support and effectively constrains the opening size during assembly, preventing structural deformation due to external forces or its own weight, ensuring the opening size meets design requirements. During assembly, the preset adjustment allowance allows for precise control of the node assembly gaps, ensuring accurate alignment of components and preventing excessive gaps from affecting structural strength or insufficient gaps from causing installation difficulties. The temporary process support 600, while constraining the opening size, also provides stable structural support throughout the assembly process, improving assembly accuracy and efficiency. After assembly is complete and the structure is stable, the temporary process support 600 is removed without affecting the final structural performance. Through this series of processes, the assembly quality of the connection node between the tail platform 400 and the crossbeam 300 is precisely controlled, ensuring the stability and reliability of the overall structure.

[0048] Reference Figure 5 In this embodiment, step S4, which involves assembling the conveyor belt frame 500, the tail vehicle platform 400, and the crossbeam 300 on the low-altitude frame 700, and then hoisting the entire assembly onto the outrigger 200, includes: Step S41: Assemble the belt conveyor frame 500, the tail car platform 400, and the crossbeam 300 on the low-altitude tire frame 700. Step S42: After the auxiliary structure is installed in place, the entire structure is hoisted to the support leg 200. The auxiliary structures include 500 belt conveyor frame components, 400 tail car platform guardrails, and 300 crossbeam walkways.

[0049] The conveyor frame 500, tail platform 400 and crossbeam 300 are assembled on the low-altitude frame 700, and the various auxiliary structures are installed in a low-altitude manner. Then, the whole assembly is installed on the outrigger 200 to reduce high-altitude construction and safety risks.

[0050] Specifically, the assembly of the conveyor belt frame 500, tail car platform 400, and crossbeam 300 is carried out before the low-altitude frame 700. The low-altitude frame 700 provides a stable and precise working platform for assembly, ensuring that each component is accurately positioned and firmly connected during the assembly process, effectively reducing the safety risks and operational difficulties associated with high-altitude operations, and improving assembly efficiency and quality. During the assembly process, the relative positions of each component can be easily adjusted and calibrated to ensure that the overall geometric dimensions of the structure meet the design requirements. After the main structure is assembled, the auxiliary structures such as the conveyor belt frame 500 accessories, tail car platform 400 guardrails, and crossbeam 300 walkway are installed in place. These auxiliary structures not only improve the functionality of the equipment but also enhance the safety and stability of the overall structure. Then, the entire assembly is hoisted to the outriggers 200. This overall hoisting avoids the tediousness and error accumulation of multiple high-altitude docking operations, ensuring the connection accuracy between components and the integrity of the overall structure. This process of assembling at low altitude, installing auxiliary structures, and then hoisting the entire structure effectively improves manufacturing precision, ensures construction safety, and makes the structure of the mobile ship loader tail car 10 more stable and reliable.

[0051] Reference Figure 6 and Figure 7 In this embodiment, step S5, adjusting the verticality of the outrigger 200 using the anti-overturning support 800 and the wave-resistant steel wire rope 900, includes: Step S51: Weld the anti-tipping support 800 ear plate and wave-wind lifting lug at the preset position of the outrigger 200; Step S52: Hoist the outrigger 200 to the installation position, detachably connect the anti-tipping support 800 to the support lug, and connect the wave wind steel wire rope 900 to the wave wind lifting lug. Step S53: Adjust the verticality of the outrigger 200 using the anti-overturning support 800 and the wave-wind steel wire rope 900.

[0052] During final assembly, anti-tipping support 800 lugs and wave wind lifting lugs are installed on the outrigger 200. The outrigger 200 is effectively adjusted by installing the anti-tipping support 800 and wave wind wire rope 900 to ensure the accuracy of the installation of the upper structure of the tail car.

[0053] First, anti-tipping support 800 lugs and wave-driven lifting lugs are welded to the preset positions of the outrigger 200. This establishes a key connection point for subsequent verticality adjustments, ensuring the adjustment device can be stably installed. Next, after hoisting the outrigger 200 to the installation position, the anti-tipping support 800 is detachably connected to the support lugs, and the wave-driven steel wire rope 900 is connected to the wave-driven lifting lugs, forming a complete verticality adjustment system. The anti-tipping support 800 provides stable support force to prevent the outrigger 200 from tipping over during adjustment; the wave-driven steel wire rope 900 applies force to the outrigger 200 from different directions by tightening or loosening. Through their coordinated operation, the position of the outrigger 200 can be precisely fine-tuned, effectively controlling its verticality to meet design requirements. This achieves precise adjustment of the outrigger 200's verticality, ensuring the stability and safety of the overall structure of the mobile ship loader stern car 10.

[0054] In this embodiment, step S53, adjusting the verticality of the outrigger 200 using the anti-overturning support 800 and the wave-resistant steel wire rope 900, includes: Step S531: Adjust the accuracy of the outrigger 200 angle ruler by adjusting the tension of the wave wind steel wire rope 900 and the length of the anti-overturning support 800.

[0055] By adjusting the tension of the wave-driven steel wire rope 900, the direction and magnitude of its pulling force on the outrigger 200 can be changed; adjusting the length of the anti-tipping support 800 can change the position of the support's point of action. These two actions work together to apply force to the outrigger 200 from different dimensions, precisely adjusting the angle of the outrigger 200 to ensure its verticality meets requirements and guarantees structural stability.

[0056] An embodiment of the present invention also provides a mobile ship loader stern car 10. The mobile ship loader stern car 10 is manufactured by a mobile ship loader stern car 10 manufacturing method.

[0057] The mobile ship loader tail car 10 is manufactured using specific methods, with a rationally arranged layout of its components. Precise welding and installation during the manufacturing process can improve upon the existing tail car manufacturing process, which is characterized by long manufacturing time, difficult assembly, difficulty in controlling dimensions, and high risks associated with high-altitude operations.

[0058] According to the embodiment of this invention, a manufacturing method for a mobile ship loader tail car 10 is provided. The working principle of the manufacturing method for the mobile ship loader tail car 10 includes: in order to effectively shorten the manufacturing process of the tail car support legs 200, provide convenience for the manufacturing, transportation and assembly of the belt conveyor frame 500, accurately control the manufacturing dimensions 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 components, a new manufacturing method for a mobile ship loader tail car 10 is designed based on the principles of safety, convenience and efficiency.

[0059] The main manufacturing processes include: Reference Figure 1 and Figure 2 To ensure the clearance between the connecting flanges 510 and the smooth installation of the bolts, a trimming allowance must be reserved when cutting the upper part of the support leg 200. A thickness allowance must also be reserved when cutting the connecting flange 510. The thickness allowance of the connecting flange 510 on the support leg 200 is directly machined to the required position. According to the dimensions required by the drawings, first fabricate the connecting support 100 into a component, then process the thickness of the connecting support flange 110 to the required level, then machine the bolt holes on the two connecting flanges 510 and tighten the bolts to ensure that the gap between the connecting flanges 510 meets the requirements. Finally, it is paired and fabricated together with the leg 200. The design of the connecting flange 210 of the leg is used as the scribing reference. The upper cutting allowance of the leg 200, as well as the machining allowance of the hole of the connecting support 100 and the weight plate, are uniformly marked. The pairing marks are made at the position of the connecting flange 510. Then, the connecting support 100 is removed. According to the scribing dimensions and the dimensions required by the drawings, the inner hole of the connecting support 100 and the allowance of the weight plate, as well as the allowance of the upper end of the leg 200 are machined, and the bevel is prefabricated in place.

[0060] Reference Figure 3 To facilitate the fabrication, transportation, and assembly of the conveyor frame 500, reduce the amount of adjustment work during assembly, and lower the welding difficulty, the structural form of the conveyor frame 500 is analyzed. Firstly, the conveyor frame 500 is divided into two parts (Component One and Component Two). Secondly, the connection points between the conveyor frame 500 and the crossbeam 300 are optimized. The flange 510 and roller assembly 520 at the connection points are fabricated separately from the conveyor frame 500 to facilitate subsequent assembly. The weld type at the connection between the conveyor frame 500 and the crossbeam 300 is optimized from overhead welding to flat welding.

[0061] Reference Figure 4 The tail platform 400 and the crossbeam 300 have many connection nodes and high welding requirements. Controlling the assembly gap at the node joint and the size of the opening at the node joint will generate a lot of adjustment work and large welding deformation. By reserving adjustment allowance at the node joint and adding temporary process support 600 at the joint opening during manufacturing, the installation gap and opening size at the node position are guaranteed. During the assembly of the tail platform 400 and the crossbeam 300, a lot of adjustment work is reduced, welding deformation is reduced, and the overall quality of the tail vehicle is improved.

[0062] Reference Figure 5 To facilitate construction, reduce high-altitude construction, decrease the frequency of use of the conveyor, reduce safety risks, and improve the integrity of components, the conveyor frame 500, tail car platform 400, and crossbeam 300 are assembled on the low-altitude jig 700, and the auxiliary structures are installed in a low-altitude manner before being installed as a whole onto the outrigger 200.

[0063] Reference Figure 6 and Figure 7To control the dimensions of the outrigger 200 and facilitate the smooth installation of the upper components of the tail vehicle, anti-tipping support 800 lugs and wave-type lifting lugs are installed on the outrigger 200. During final assembly, after the outrigger 200 is hoisted into place, the anti-tipping support 800 and wave-type steel wire rope 900 are installed to effectively adjust the outrigger 200, ensuring the accuracy of the installation of the upper structure of the tail vehicle and improving the overall quality of the project.

[0064] The manufacturing method of the mobile ship loader stern car 10 provided in this embodiment has at least the following advantages: To ensure the gap between the connecting flanges 510 and to control the welding deformation of the flanges 510, the outrigger 200 and the trolley connecting support 100 are required to be manufactured together. The outrigger connecting flange 210 is set as the scribing reference to facilitate the uniform marking of the upper cutting allowance of the outrigger 200, as well as the machining allowance of the hole of the connecting support 100 and the weight plate, thereby reducing manufacturing errors and improving the quality of the components.

[0065] To address the challenges of diverse connection points and complex welding between the conveyor frame 500 and the crossbeam 300, the conveyor frame 500 was rationally segmented, and the connection points with the crossbeam 300 were optimized. The flanges 510 and roller assemblies 520 at the connection points were fabricated separately from the conveyor frame 500, and overhead welding was optimized to flat welding. This facilitated the fabrication, transportation, and assembly of the conveyor frame 500, reduced adjustment work during assembly, lowered welding difficulty, and improved manufacturing efficiency.

[0066] The tail platform 400 and the crossbeam 300 have many connection nodes and high welding requirements. The control of the gap at the node joint position and the size of the opening will generate a lot of adjustment work and large welding deformation. By reserving adjustment margin at the node joint position and adding temporary process support 600 at the joint position opening during the manufacturing process, the installation gap and opening size at the node position are guaranteed.

[0067] To facilitate construction, reduce high-altitude construction, lower safety risks, and improve the integrity of components, the belt conveyor frame 500, tail car platform 400, and crossbeam 300 are assembled on the low-altitude jig 700 and then installed as a whole onto the outrigger 200.

[0068] During the final assembly phase, to control the dimensions of the outriggers 200 and ensure smooth installation of the upper components of the tail car, anti-tipping support 800 lugs and wave-lift lugs were installed on the outriggers 200. During final assembly, the outriggers 200 were effectively adjusted by installing the anti-tipping supports 800 and wave-lift wire ropes 900, ensuring accurate installation of the upper structure of the tail car, improving the overall quality of the project, and enabling the mobile ship loader tail car 10 to be better put into use.

[0069] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
