Description

TECHNICAL FIELD

[0001] The present application relates to the field of container design, in particular to a method for assembling a multi-corner piece multi-corner column container. BACKGROUND

[0002] A container is composed of six faces: a chassis assembly, a front end assembly, a rear end assembly, a left side assembly, a right side assembly, and a top plate assembly. When welding these six face assemblies on the production line, they are also assembled one by one in the above order and welded and fixed. In this way, the six face assemblies are pre-produced and assembled in order during assembly, which is suitable for assembly line production, has high production efficiency, and good quality control.

[0003] The main assembly procedures are: chassis fixation, fixation of front and rear ends and left and right side walls, spot welding of side wall connections, inside side plate welding, top plate reinforcement plate welding, top plate fixation (spot welding), side plate and front and rear corner column automatic welding, top plate automatic welding, trimming, polishing, and slag removal, whole container sanding, painting, and floor laying.

[0004] For multi-corner piece multi-corner column combined containers, such as 10' + 10' = 20', 20' + 20' = 40', 10' + 30' = 40', etc. for warehouse containers and logistics containers. In this way, two containers are combined to form a standard 20' or 40' container, and the combined standard container is often the most cost-effective during transportation.

[0005] However, when producing and manufacturing such multi-corner piece multi-corner column combined containers on a container production line, the production is often difficult and inefficient due to the addition of one or more corner pieces and corner columns in the middle of the container. For example, one end of the container is welded as a whole container (A container), the other end of the container is welded as a whole container (B container), and the two containers are connected together through a corner piece connecting plate. In this way, it is equivalent to a second assembly, and the second assembly production process has two problems: first, there is no suitable second assembly station on the standard production line, and the production is inefficient; second, the A / B combined container assembled in this way is often not straight, commonly known as a swing head. SUMMARY

[0006] Therefore, it is necessary to provide a method for assembling a multi-corner piece multi-corner column container to solve at least some of the above problems.

[0007] A method for assembling a multi-corner piece multi-corner column container, comprising the following steps:

[0008] Preparation: two-by-two combination to form a doorless end frame pre-assembly, and preparation of two chassis assemblies, two door end frames, four side plate assemblies, and two top plate assemblies;

[0009] Body fixing: fixing the doorless end frame pre-assembly to the middle of the production line assembly table, operating two chassis assemblies to be respectively positioned on the two sides of the doorless end frame pre-assembly, and the two chassis assemblies are respectively fixed to one doorless end frame, operating two door end frames to be respectively positioned at the far end of the two chassis assemblies away from the doorless end frame pre-assembly, and connecting and fixing the door end frame and the corresponding chassis assembly, operating four side plate assemblies to connect the edges of the doorless end frame, the door end frame and the chassis assembly to form a containing space of the box body together; operating the top plate assembly to cover the top of the box body;

[0010] Body welding: welding the connecting parts of the side plate assembly, the doorless end frame pre-assembly, the door end frame, the chassis assembly and the top plate assembly together.

[0011] The above-mentioned assembly method of the multi-angle piece multi-angle column box has at least the following beneficial technical effects:

[0012] In the assembly process of the present application, the doorless end frame pre-assembly is taken as the center to assemble one box body on each side, at this time, two or more box bodies can be assembled on one table at the same time, and production can be directly carried out on the existing production line. Since the production is directly assembled on the original production line, it is not necessary to build a new production line outside the existing production line, and it is not necessary to carry out secondary assembly and set up a secondary assembly table, so the efficiency is high; the combined box body assembled at one time is straight in length, and the head shaking phenomenon is eliminated.

[0045] As shown in Figures 1-3 An embodiment of the present application provides an assembling method of a multi-angle piece multi-angle column box, comprising the following steps:

[0046] Preparation: two-by-two combination to form a doorless end frame pre-assembled component 100, and two chassis assemblies 200, two door end frames 300, four side plate assemblies 400 and two top plate assemblies 500 are prepared;

[0047] Main body fixing: fixing the doorless end frame pre-assembled component 100 to the middle of the production line assembly table, operating two chassis assemblies 200 to be respectively positioned on both sides of the doorless end frame pre-assembled component 100 and fixedly connected with one doorless end frame 1 respectively, operating two door end frames 300 to be respectively positioned at the far ends of the two chassis assemblies 200 away from the doorless end frame pre-assembled component 100, and fixedly connecting the door end frames 300 with the corresponding chassis assemblies 200, operating four side plate assemblies 400 to connect the edges of the doorless end frame 1, the door end frame 300 and the chassis assembly 200 to form a containing space of the box body together, and operating the top plate assembly 500 to cover the top of the box body;

[0048] Main body welding: welding the connecting parts of the side plate assembly 400, the doorless end frame pre-assembled component 100, the door end frame 300, the chassis assembly 200 and the top plate assembly 500 together.

[0049] In the method of the present application, two doorless end frames 1 are first combined into a doorless end frame pre-assembled component 100 and fixed on the pre-set assembly position of the production line assembly table, that is, the doorless end frame pre-assembled component 100 has formed an integrated subassembly before assembly; then two or more chassis assemblies 200 are aligned and positioned from both sides to the doorless end frame pre-assembled component 100 and fixedly connected, and finally two door end frames 300 are operated to be fixedly connected with the far ends of the two chassis assemblies 200 away from the doorless end frame pre-assembled component 100.

[0050] As described above, the present application is assembled with no door end frame pre-assembly 100 as the center to the two sides of the box body, at this time two or more box bodies can be assembled at the same time on a station, which can be directly produced on the existing production line. Because of the direct assembly production on the original production line, it is not necessary to build a new production line outside the existing production line, and it is not necessary to carry out secondary assembly and set up a secondary assembly station, which is high in efficiency; the assembled combination box body is straight in length, and the head shaking phenomenon is eliminated.

[0051] It is worth noting that after the main body is welded, the following steps are further included: post-welding finishing: polishing, removing welding slag, whole-box sanding, painting, and laying floor.

[0052] Reference Figure 3 In some embodiments, in the main body fixing, the steps of respectively placing two chassis assemblies 200 on the two sides of the doorless end frame pre-assembly 100 and respectively fixing the two chassis assemblies 200 to one doorless end frame 1, include:

[0053] Aligning the two chassis assemblies 200 to the two sides of the doorless end frame pre-assembly 100 and respectively abutting the two chassis assemblies 200 to one doorless end frame 1, and fixing the bottom side beams 210 of the chassis assemblies 200 to the assembly table surface by using a plurality of presser foot toolings 1000 on the assembly table surface;

[0054] Reference Figure 4 In some embodiments, the presser foot tooling 1000 includes:

[0055] A fixed support 1100;

[0056] A presser foot block 1200 hinged to the fixed support 1100, and the presser foot block 1200 includes a vertical pressing surface 1201 and a horizontal pressing surface 1202, and the presser foot block 1200 is configured to be arranged towards the bottom side beam 210;

[0057] A power device 1300 hinged at one end to the assembly table surface and hinged at the other end to the presser foot block 1200, for driving the presser foot block 1200 to swing towards the bottom side beam 210, and for enabling the presser foot block 1200 to laterally embed and press against the side surface and the upper surface of the fixed bottom side beam 210.

[0058] Specifically, the power device 1300 is started to drive the presser foot block 1200 to swing towards the bottom side beam 210, and the vertical pressing surface 1201 and the horizontal pressing surface 1202 of the presser foot block 1200 press against the side surface and the upper surface of the fixed bottom side beam 210 from the side, thereby achieving vertical and horizontal positioning and fixing of the two side bottom side beams 210 of the chassis assembly 200, and avoiding position deviation or welding deformation of the finished product caused by shaking during assembly.

[0059] Reference Figure 3In some embodiments, in the main body fixing step of fixing the doorless end frame pre-assembly 100 to the middle of the production line, the step includes:

[0060] A first bottom corner piece support block 2000 is arranged at a position corresponding to the positions of the two doorless end frames 1 in the middle of the production line assembly table, and the doorless bottom corner pieces 1-3 of the two doorless end frames 1 are arranged on the first bottom corner piece support block 2000.

[0061] Specifically, the first bottom corner piece support block 2000 is arranged at a position corresponding to the positions of the two doorless end frames 1 in the middle of the production line assembly table, which can continuously position and support the two doorless end frames 1 during the main body fixing and main body welding processes, avoiding the shaking of the two doorless end frames 1 during the fixing and welding processes, and preventing the multi-corner piece multi-corner column box product from being skewed or having a head shaking phenomenon.

[0062] Reference Figure 3 In some embodiments, in the main body fixing step of positioning the two door- equipped end frames 300 at the distal ends of the two chassis assemblies 200 away from the doorless end frame pre-assembly 100, the step includes:

[0063] The door-equipped bottom corner pieces 310 of the two door-equipped end frames 300 are arranged on the second bottom corner piece support block 3000, and the door-equipped top corner pieces 320 of the two door-equipped end frames 300 are pressed downward by the top corner piece presser 4000, so as to position the two door-equipped end frames 300 at the distal ends of the two chassis assemblies 200 away from the doorless end frame pre-assembly 100.

[0064] Specifically, the second bottom corner piece support block 3000 and the top corner piece presser 4000 are used to cooperatively clamp and position the two door-equipped end frames 300 from the bottom and the top, respectively, which can continuously and firmly position and fix the two door-equipped end frames 300 during the main body fixing and main body welding processes, avoiding the shaking of the two door-equipped end frames 300 during the fixing and welding processes, and preventing the multi-corner piece multi-corner column box product from being skewed or having a head shaking phenomenon.

[0065] In some embodiments, in the main body fixing step of connecting the edges of the doorless end frame 1, the door-equipped end frame 300, and the chassis assembly 200 to form a containing space of the box, the step includes:

[0066] The four side plate assemblies 400 are aligned and fixed on the two sides of the two chassis assemblies 200, and the connection between the side plate assembly 400 and each end frame and chassis assembly 200 is spot welded.

[0067] In this embodiment, after the four side plate assemblies 400 are fixed to both sides of the two base frame assemblies 200, the connection between the side plate assemblies 400 and each end frame and base frame assembly 200 is initially spot welded. This can initially fix the relative position between the side plate assemblies 400 and each end frame and base frame assembly 200, preventing the relative position from being skewed during subsequent main body welding.

[0068] In some embodiments, the step of welding the joints of the side panel assembly 400, the doorless end frame pre-assembly 100, the door-mounted end frame 300, the base frame assembly 200, and the top plate assembly 500 together in the main body welding includes:

[0069] Weld the inner side of the side panel assembly 400 to the doorless end frame pre-assembly 100, the door end frame 300, and the base frame assembly 200; weld the side panel assembly 400 to each corner post; and weld the operating top plate assembly 500 to the side panel assembly 400 and each end frame.

[0070] Specifically, after the main body is fixed, the inner side of the side panel assembly 400 is welded together with the doorless end frame pre-assembly 100, the door end frame 300, and the base frame assembly 200 inside the box. The side panel assembly 400 is also welded to each corner post to enhance the structural strength of the box. Finally, the top panel assembly 500 is welded to the side panel assembly 400 and each end frame to complete the assembly of the multi-corner multi-corner post box, forming a combined sealed long box.

[0071] In some embodiments, in the step of forming the doorless end frame pre-assembly 100 by the above-described combination, the assembly is performed using a container end frame assembly positioning fixture. For example... Figures 5-9 As shown, the container end frame assembly positioning fixture includes:

[0072] Tooling base 10;

[0073] Multiple supporting components 20 are provided and distributed on the surface of the tooling base 10. Each supporting component 20 has a supporting placement surface 21, which is used to place and support the four corners of the doorless end frame 1.

[0074] A blocking mechanism is provided on the surface of the tooling base 10 and located on the outer periphery of the doorless end frame 1, for blocking the side of the doorless end frame 1 to limit the translation of the doorless end frame 1 in the horizontal plane.

[0075] Specifically, after stacking the two doorless end frames 1 one on top of the other, they can be placed flat on the support surface 21 of the support component 20. Then, the outer perimeter blocking mechanism is used to block and restrict the doorless end frames 1 from moving horizontally, so that the two doorless end frames 1 are fixed in position on the horizontal plane. At this time, the two doorless end frames 1 can be welded together to achieve rapid assembly and fixation of the two doorless end frames 1. During welding, the position of the doorless end frames 1 is fixed, which can ensure the connection strength and connection fixation quality after the two doorless end frames 1 are connected.

[0076] This embodiment can quickly assemble two identical doorless end frames 1. The connection strength and connection fixation quality of the two doorless end frames 1 are good. The two welded doorless end frames 1 are placed at the joint of the two containers. After the two containers are connected, it is very convenient to lift and stack them. They can also be snapped into the slots on the deck surface of the container ship, which improves the transfer efficiency.

[0077] Because the two end frames can be assembled independently, there is no need to purchase complex connectors, which would result in high procurement costs; the two connected containers have high overall strength, can pass the lateral rigidity test, and can meet the requirements for high stacking. During sea transport, they can be placed in higher positions without incurring higher fees than standard containers, thus greatly reducing transportation costs.

[0078] refer to Figure 7 In some embodiments, there are four supporting components 20, distributed at the four corners of the surface of the tooling base 10. Specifically, as shown in the figure, there is one supporting component 20 at each of the four positions, used to support the doorless end frame 1. On the one hand, the supporting components 20 at the four corners can fully support the doorless end frame 1; on the other hand, the number of four supporting components 20 is small, which helps to reduce production costs.

[0079] refer to Figures 5-7 In some embodiments, the blocking mechanism includes:

[0080] A transverse blocking structure 30 is provided adjacent to a supporting component 20 to block the longitudinal side frame 1-1 of the end frame to limit the horizontal translation of the doorless end frame 1 towards the periphery of the doorless end frame 1 in the horizontal plane.

[0081] A longitudinal blocking structure 40 is disposed adjacent to a supporting component 20 to block the lateral side frame 1-2 of the end frame to limit the doorless end frame 1 from translating longitudinally toward the periphery of the doorless end frame 1 in the horizontal plane, wherein the longitudinal direction is perpendicular to the lateral direction.

[0082] Specifically, the side of the end frame is formed by the longitudinal side frame 1-1 extending longitudinally and the transverse side frame 1-2 extending transversely. The transverse blocking structure 30 and the longitudinal blocking structure 40 can block and restrict the longitudinal side frame 1-1 and the transverse side frame 1-2 of the end frame, respectively, thereby restricting the translation of the doorless end frame 1 towards the periphery of the end frame in the horizontal plane along the transverse and longitudinal directions.

[0083] Specifically, refer to Figure 5 and Figure 8 In some embodiments, the lateral blocking structure 30 is a lateral blocking plate, the first blocking surface 31 of the lateral blocking plate is vertically arranged and faces the longitudinal side frame 1-1 of the end frame, and the lateral blocking plate is connected to one of the supporting components 20.

[0084] Specifically, the transverse blocking plate is vertically arranged and faces the longitudinal side frame 1-1 of the end frame, and the first blocking surface 31 of the transverse blocking plate can block the longitudinal side frame 1-1 of the end frame. The two functional components are integrated, which is convenient for assembly and improves the assembly accuracy.

[0085] Reference Figure 7 In some embodiments, the transverse blocking structure 30 is two, which are arranged in sequence along the longitudinal direction perpendicular to the transverse direction. For example, two transverse blocking plates are vertically arranged and face the longitudinal side frame 1-1 of the end frame. The number of the transverse blocking structure 30 is large, which can better block the longitudinal side frame 1-1 of the end frame.

[0086] Reference Figure 7 In some embodiments, the longitudinal blocking structure 40 includes a longitudinal blocking plate arranged on the side of the adjacent supporting component 20 away from the doorless end frame 1. As shown in Figure 6 , the second blocking surface 41 of the longitudinal blocking plate is vertically arranged and faces the transverse side frame 1-2 of the end frame.

[0087] Specifically, the longitudinal blocking plate is vertically arranged and faces the transverse side frame 1-2 of the end frame, and the second blocking surface 41 of the longitudinal blocking plate can block the transverse side frame 1-2 of the end frame to prevent it from moving in the longitudinal direction.

[0088] In some embodiments, the longitudinal blocking structure 40 includes one or two longitudinal blocking plates. Figure 10 and Figure 11 respectively shows the longitudinal blocking structure 40 at the upper right corner and the lower right corner of Figure 3 , the longitudinal blocking structure 40 in Figure 10 has two longitudinal blocking plates, and the two longitudinal blocking plates are vertically arranged and face the transverse side frame 1-2 of the end frame, Figure 11 the longitudinal blocking structure 40 in only has one longitudinal blocking plate. The number of the longitudinal blocking plates is large, which can better block the transverse side frame 1-2 of the end frame.

[0089] Figure 5 Reference In some embodiments, the pressing mechanism 50 is arranged on the surface of the tool base 10 and is used to block the upper surface of the doorless end frame 1 to limit the upward movement of the doorless end frame 1.

[0090] Specifically, the pressing mechanism 50 can be a locking pressing rod that can be adjusted up and down. When the lower end surface 51 of the pressing rod abuts against the upper surface of the doorless end frame 1, the upward movement of the doorless end frame 1 is limited.

[0091] The pressing mechanism 50 can block and limit the upward movement of the doorless end frame 1, so that the vertical positions of the two doorless end frames 1 are fixed and positioned, and the doorless end frame 1 will not jump during the welding process of the two doorless end frames 1, which is beneficial to the rapid assembly and connection of the two doorless end frames 1, and the doorless end frame 1 will not jump up and down during welding, and the connection strength and connection fixing quality of the two doorless end frames 1 after connection can be ensured.
