DETAILED DESCRIPTION

[0038] The present invention will be described in detail below with reference to the accompanying drawings, but is not limited thereto.

[0039] Example 1

[0040] Figure 1 It is a partial structural schematic diagram of the tank container end frame of the present invention. Figure 2 It is a top view schematic diagram of the tank container end frame assembly device of the present invention. Figure 3 It is a schematic front view of the tank container end frame assembly device of the present invention.

[0041] like Figure 1 As shown, the tank container end frame primarily comprises an upper end beam 100, a lower end beam 110, corner posts 120, and corner fittings 130. Corner fittings 130 are used to connect corner posts 120 to upper end beam 100, and vice versa. During assembly using the assembly device of the present invention, corner posts 120 and corner fittings 130 are already welded together and have been inspected for quality.

[0042] like Figure 2 and 3 As shown, the tank container end frame assembly device includes: an assembly platform 1, a rotary pressing mechanism 2, a supporting and positioning mechanism 3, a lateral pressing mechanism 4 and a positioning block 5.

[0043] like Figure 3As shown, the assembly platform 1 includes an assembly base 11, support columns 12 and a reinforcing beam 13. The assembly base 11 is configured as a rectangular plate structure, which has a first edge 111, a second edge 112, a third edge 113 and a fourth edge 114, wherein the first edge 111 and the second edge 112 are relatively parallel; the third edge 113 and the fourth edge 114 are relatively parallel. A plurality of support columns 12 are provided on the lower surface of the assembly base 11, and two reinforcing beams 13 are provided between two adjacent support columns 12, wherein one reinforcing beam 13 is provided horizontally, and its two ends are respectively fixed to the two adjacent support columns 12, and the other reinforcing beam 13 is provided vertically, and one end is connected to the lower surface of the assembly base 11, and the other end is connected to the transversely provided reinforcing beam 13, thereby increasing the strength and rigidity of the assembly base 11. In this way, the stability of the entire assembly platform 1 can be achieved.

[0044] like Figure 2 As shown, eight rotary clamping mechanisms 2 are provided, spaced apart and positioned near the edges of the assembly base 11. Four of the rotary clamping mechanisms 2 are symmetrically positioned around the center point of the assembly base 11 near the four corners of the rectangular assembly base 11, and the remaining four rotary clamping mechanisms 2 are located in the middle of the four edges of the assembly base 11. The rotary clamping mechanisms 2 are configured to vertically clamp the tank container end frame.

[0045] like Figure 3 As shown, the rotary clamping mechanism 2 includes a column 21, a rotary support 22, an extension arm 23, a screw 24, and a pressure block 25. The column 21 is fixedly connected to the upper surface of the assembly base 11. The rotary support 22 is located at the top of the column 21. An extension arm 23 is provided on the side of the rotary support 22, perpendicular to the rotary support 22. A through hole is provided at the end of the extension arm 23 away from the rotary support 22. A screw 24 is screwed into the through hole. Pressure blocks 25 are provided at both ends of the screw 24. The rotary support 22 drives the extension arm 23 to rotate, thereby adjusting the position of the extension arm 23, and further adjusting the position of the screw 24 and the pressure block 25, thereby more flexibly positioning and clamping the tank container end frame. In this embodiment, the through hole is configured as a threaded hole, and the screw 24 is a screw.

[0046] like Figure 2 As shown, four support and positioning mechanisms 3 are provided. These four support and positioning mechanisms 3 are provided corresponding to the four rotational clamping mechanisms 2 located near the four corners of the rectangular assembly base 11. Each support and positioning mechanism 3 is located on the inner side of the corresponding rotational clamping mechanism 2 (i.e., on the side away from the edge of the assembly base 11). The support and positioning mechanisms 3 are used to support and position the corner piece 130.

[0047] The support and positioning mechanism 3 includes a support base 31 and a stopper 32. The support base 31 is configured as a rectangular plate-like structure. The support base 31 is located on the side of the column 21 facing away from the edge of the assembly base 11. The stopper 32 is provided on the upper surface of the support base 31 and is used to limit the corner piece 130. In this embodiment, the stopper 32 for limiting the corner piece 130 at both ends of the upper end beam 100 is configured as an L-shaped plate-like structure, which can limit the corner piece 130 from the front-to-back direction and the left-to-right direction; the stopper 32 for limiting the corner piece 130 at both ends of the lower end beam 110 is configured as a rectangular plate-like structure, which only limits the corner piece 130 from the left-to-right direction, which makes it more convenient to remove the pieces.

[0048] like Figure 2 As shown, two lateral tightening mechanisms 4 are provided, which are spaced apart at the second edge 112 near the assembly base 11 and symmetrically arranged at a position near the supporting positioning mechanism 2 with the center line of the second edge 112 as the symmetry axis, and are used to tighten the corner pieces 130 at both ends of the lower end beam 110 from the lateral direction and eliminate the gap.

[0049] The lateral tightening mechanism 4 includes a support and a tightening component. The support is set as a plate-like structure and is perpendicular to the upper surface of the assembly platform 1. A fixing hole is opened on the support. The tightening component is screwed into the fixing hole to tighten the side of the angle piece 130.

[0050] like Figure 2 As shown, the positioning blocks 5 include an upper beam positioning block 51, a lower beam positioning block 52, and a corner column positioning block 53. Two upper beam positioning blocks 51 are provided. These two upper beam positioning blocks 51 are spaced apart near the first edge 111 and symmetrically arranged between two adjacent support and positioning mechanisms 2 with the centerline of the first edge 111 as the axis of symmetry, for supporting and positioning the upper beam 100. Two lower beam positioning blocks 52 are provided. These two lower beam positioning blocks 52 are spaced apart near the second edge 112 and symmetrically arranged between two adjacent support and positioning mechanisms 2 with the centerline of the second edge 112 as the axis of symmetry, for supporting and positioning the lower beam 110. The centerlines of the first edge 111 and the second edge 112 coincide with each other. Two corner column positioning blocks 53 are provided. These two corner column positioning blocks 53 are respectively arranged to correspond to the rotary clamping mechanisms 2 located in the middle of the third edge 113 and the fourth edge 114 of the rectangular assembly base 11, for positioning and supporting the corner columns 120.

[0051] The following describes a method for assembling a tank container end frame using the tank container end frame assembly device of this embodiment:

[0052] First, the corner pieces 130 and the corner columns 120 are welded together and inspected to be of qualified quality to form corner components. Then, the upper end beam 100, the lower end beam 110, and the corner components are correspondingly enclosed to form the shape of the end frame. Among them, the corner pieces 130 are located on the support base 31, and the two corner pieces 130 at the ends of the upper end beam 100 are limited in the L-shaped stopper 32, and the two corner pieces 130 at the ends of the lower end beam 110 are limited in the left and right stoppers 32. The upper end beam 100 is placed on the upper end beam positioning block 51, and the lower end beam 110 is placed on the upper end beam positioning block 51. The brackets 120 are placed on the lower beam positioning block 52, and the corner posts 120 are placed on the corner post positioning block 53, achieving rapid positioning. The lateral tightening mechanism 4 then uses its tightening components to limit the sides of the two corner pieces 130 at the ends of the lower beam 110, eliminating any gaps. Finally, the rotating support 22 drives the extension arm 23 to rotate, adjusting the extension arm 23 to the appropriate position. The screw rod 24 is screwed into the through hole, and the pressure block 25 at the end of the screw rod 24 abuts against the top of the end frame, vertically compressing the end frame. After assembly is complete, subsequent welding work is performed.

[0054] In this embodiment, only one upper end beam positioning block 51 and one lower end beam positioning block 52 are provided, which are respectively provided corresponding to the rotary clamping mechanism 2 near the middle position of the first edge 111 and the second edge 112.
