Description

Technical Field

[0001] This utility model relates to the field of large parts transportation technology, specifically to a tooling for packing and shipping large-diameter bent pipes. Background Technology

[0002] When shipping large-diameter pipes in containers, the pipes must be secured inside the container to prevent radial or axial displacement during transportation, which could lead to collisions or other problems.

[0003] For large-diameter bends, due to their irregular shape, they are generally secured with wooden pallets or blocks during packing and shipping. Multiple bends are isolated and protected with rubber pads, or multiple-layer straight racks are used for securing them. Currently, the common method of securing large-diameter bends with wooden pallets and blocks, and using rubber pads to isolate and protect multiple bends, can lead to collisions between pipes and damage to the paint on the surface of the bends during transportation or transshipment due to inadequate protection. This can easily cause customer complaints, and the pipes need to be loaded one by one when loading them into containers, resulting in low work efficiency. If multiple-layer straight racks are used for securing them, this method can avoid collisions, but it occupies a lot of space, resulting in low space utilization when loading them into containers and high transportation costs.

[0004] In the prior art, CN113247469B discloses a portable pipeline support assembly for a tank container, including a storage tank and a container frame formed around the tank. The side of the container frame is adjustablely fitted with a side-opening support plate that supports and houses the pipeline. The side of the container frame is provided with a loading base plate for mounting the side-opening support plate. The side-opening support plate is hinged to the loading base plate. A driving member is provided on the side of the loading base plate away from the mounting position of the side-opening support plate. The driving member drives the side-opening support plate to rotate around the hinged position between the side-opening support plate and the loading base plate. An extendable bearing member is provided below the loading base plate. The bearing member, in conjunction with the driving member, provides support for the side-opening support plate in a horizontal state. This structure is used to fix storage tanks, which are large-diameter pipes with sealed ends. Although this structure can fix large-diameter storage tanks well, it can only fix a single large-diameter pipe. When the container cross-section can accommodate multiple large-diameter pipes, this fixing method will inevitably cause huge waste of space. In addition, this fixing structure is not convenient to remove the pipe from the frame. Furthermore, this structure is not convenient to fix bends.

[0005] In view of the above, it is necessary to propose a large-diameter bent pipe packing and shipping tool to solve the above problems. Utility Model Content

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0031] Example 1:

[0032] The large-diameter bent pipe fitting 1 of this utility model is L-shaped, having a straight pipe section 2 and a bend head 3. A short bend head 3 is connected to one end of the straight pipe section 2, and flanges 4 are provided at both ends of the large-diameter bent pipe fitting 1. Based on the specific shape of the above-mentioned workpiece, a large-diameter bent pipe packing and shipping fixture is manufactured, such as... Figure 1-5 As shown, the tooling is a pallet frame structure, which can be made from materials such as square steel tubes, H-beams, C-beams, or L-beams. The tooling frame specifically includes a bottom frame 5 forming the bottom pallet, and a support frame 6 vertically mounted on the bottom frame 5. During manufacturing, the width of the bottom frame 5 is matched with the internal width of the container. This facilitates the placement of fixed pipe fittings along with the tooling into the container. It is understood that the application of this tooling is not limited to containers, but can also be used in rectangular transport equipment such as trucks and train carriages.

[0033] The pipe bend fitting 1 is fixed to the tooling frame in pairs, such as... Figure 1 As shown, the bends 3 of the two bent pipe fittings 1 are respectively placed at both ends of the tooling frame. Since the diameter of the bent pipe is relatively large, fixing only one bent pipe in each container would waste a lot of space. Therefore, to make full use of the space inside the container, in this embodiment, the two bent pipes are placed in a staggered manner, with one bent pipe located on the lower side and the other on the upper side, so that the two bent pipes are arranged in the same cross-section as shown... Figure 4 As shown, the straight section 2 of the bend is staggered in the longitudinal direction; thus, more large-diameter bend fittings 1 can be installed in the limited container space.

[0034] Specifically, as Figure 1 and 4 shown, the support upright frame 6 forms a support foundation for the elbow pipe fitting 1 located on the upper side, and the bottom frame body 5 forms a support foundation for the elbow pipe fitting 1 located on the lower side; as Figure 2 shown, two end regions of the tooling frame body form elbow fixing regions 7, and between the two elbow fixing regions 7 is a straight pipe fixing region 8. Since the bent head 3 of the elbow pipe fitting 1 occupies more lateral space when placed compared to the straight pipe portion 2, the bent pipe portions of the two elbow pipe fittings 1 both extend out of the straight pipe portion 2 of the other for fixing, as Figure 1 shown, the bent pipe portions are both fixed in the elbow fixing regions 7, and the two straight pipe portions 2 are both fixed in the straight pipe fixing region 8.

[0035] Specifically, the bottom frame body 5 has a rectangular frame structure and includes a first cross beam 9 and a second cross beam 10. At least two first cross beams 9 are provided and arranged in parallel to each other, and multiple second cross beams 10 are arranged vertically between the first cross beams 9. Two ends of the second cross beam 10 are respectively fixedly connected to the first cross beam 9. In this embodiment, as Figure 2 shown, two first cross beams 9 are provided, and four second cross beams 10 are successively provided between the two first cross beams 9, forming a structure in the shape of a Chinese character "mu". Specifically, the second cross beam 10 is successively divided into cross beam one 24, cross beam two 25, cross beam three 26, and cross beam four 27.

[0036] The elbow fixing region 7 at least includes two second cross beams 10 arranged in parallel to each other. Specifically, an elbow fixing region 7 is formed between cross beam one 24 and cross beam two 25, and another elbow fixing region 7 is formed between cross beam three 26 and cross beam four 27;

[0037] The inner second cross beams 10 (i.e., cross beam two 25 and cross beam three 26) form the positioning of the flange 4 at the end of the straight pipe section. Specifically, as Figure 1 and 2 shown, one end of the horizontally placed elbow pipe 29 is positioned on cross beam three 26, and the other end is supported on cross beam two 25; the outer second cross beam 10 (cross beam one 24) forms the positioning of the flange 4 of the bent head 3, that is, the bent head 3 of the horizontally placed elbow pipe 29 is located in the elbow fixing region 7 between cross beam one 24 and cross beam two 25. As Figure 1 and 2 shown, the horizontally placed elbow pipe 29 and the vertically placed elbow pipe 30 shown in the figure can be understood as taking the bent head 3 as the standard. When the bent head 3 is placed horizontally, it is defined as the horizontally placed elbow pipe 29, and when the bent head 3 is placed vertically for positioning, it is defined as the vertically placed elbow pipe 30; it can be understood that the flange 4 at the bent pipe end of the horizontally placed elbow pipe 29 can have a certain inclination angle, as Figure 1 [[ID=2))shown; then in order to adapt to the fixing of the inclined flange 4, a slanting baffle 15 is correspondingly provided in this embodiment. One end of the bottom frame body 5 is provided with a slanting baffle 15 that fits the end face of the flange 4; specifically, as Figure 2 As shown, a connecting beam 28 is vertically arranged between the first crossbeam 24 and the second crossbeam 25. An inclined baffle 15, which fits against the inclined flange 4, is fixedly installed on the first crossbeam 24 and the connecting beam 28. One side of the inclined baffle 15 can be used for locking and limiting, and the other side can be assembled and connected with the flange 4 to form a fixed structure. Specifically, as shown... Figure 4 As shown, a through hole 23 corresponding to the flange 4 is provided on the inclined baffle 15, and bolts are used to pass through the through hole 23 and the flange 4 to lock and fix them.

[0038] Furthermore, at least one of the inner second crossbeams 10 is provided with a support frame 6, such as... Figure 2 , 3 As shown in Figure 4, the support frame 6 includes a first support rod 11, a second support rod 12, and a crossbeam 13. The crossbeam 13 is fixedly mounted on the upper part of the first support rod 11 and the second support rod 12. The lower ends of the first support rod 11 and the second support rod 12 are vertically fixed to an inner second crossbeam 10. The first support rod 11 is positioned close to one side of the first crossbeam 9. Diagonal braces 14 are provided between the first support rod 11 and the first crossbeam 9 on both sides. The crossbeam 13 is raised and supported by the first support rod 11 and the second support rod 12 and is located above the second crossbeam 25. The diagonal braces 14 on both sides form a reinforced fixation to prevent swaying and displacement. When fixing large-diameter bent pipe fittings 1, such as... Figure 1 , 4 As shown, a through hole 23 is also provided on the crossbeam 13 to cooperate with the flange 4. The flange 4 of the straight pipe part 2 is attached to the crossbeam 13, and bolts are inserted to fix this end. The flange 4 at the other end can be fastened to the crossbeam 27. Similarly, a through hole 23 is also provided on the crossbeam 27. After the flange 4 is locked and fixed to the through hole 23, the fixation of the two bent pipe fittings 1 is completed.

[0039] Example 2:

[0040] The structure of this embodiment is largely the same as that of Embodiment 1, except that the length of the bottom frame 5 in this embodiment is adjustable. Specifically, the first crossbeam 9 has an adjustable length. In actual use, the first crossbeam 9 can be divided into two interlocking sections, allowing for length adjustment. Multiple adjustment holes 31 are provided at the joint of the crossbeam, and fixing bolts are inserted into the adjustment holes 31. When the length needs to be changed, simply loosen the fixing bolts, adjust the length of the first crossbeam 9, align the adjustment holes 31, and then insert the fixing bolts again. Figure 1 The diagram shows two different lengths of bottom frame 5, and a large-diameter bent pipe fitting 1 of different lengths is fixed thereon.

[0041] Furthermore, a sliding plate 32 is provided on the support legs at the lower end of the bottom frame 5. The sliding plate 32 is installed at the bottom of the entire tooling frame, allowing it to slide smoothly into the container when it is loaded as a whole.

[0042] A method for using a large-diameter bent pipe packing and shipping fixture includes the following steps:

[0043] S1. Adjust the length of the first crossbeam 9 according to the length of the bent pipe fitting 1, and adjust the length of the bottom frame 5 to a suitable position; specifically, loosen the fixing bolts, then adjust the length of the first crossbeam 9, align the adjusting hole 31, and then insert the fixing bolts; the advantage is that it can be extended and adjusted according to the length of different loaded goods, and then fixed with locking bolts after adjustment.

[0044] S2, pre-set through holes 23 corresponding to the positions of flange 4 on the crossbeam 3 26 and the inclined baffle 15. First, place the flat bend 29 on the bottom frame 5. The flange 4 at the straight end corresponds to the position of the through hole 23 and is fixed with bolts. Position the inclined baffle 15 according to the position of the flange 4 at the bend end and weld it to the bottom frame 5. Fix the flange 4 and the through hole 23 of the inclined baffle 15 with bolts. The position of the through hole 23 is matched with the installation position of different bends to achieve high-precision matching.

[0045] S3, pre-set through holes 23 corresponding to the positions of flange 4 on the crossbeam 4 27 and the crossbar 13, and vertically position the bent pipe 30 on the crossbeam 4 27 and the crossbar 13. Insert bolts into the flanges 4 at both ends and the through holes 23 on the crossbeam 4 27 and the crossbar 13 respectively to fix them. Similar to step two, use the through holes 23 to fix the flanges 4, thereby fixing the large-diameter bent pipe.

[0046] S4, a rubber pad is filled between the two bends for fixation, providing double protection; steel wire can also be used for fixation.

[0047] S5, weld lifting lugs at appropriate positions on the bottom frame 5. This facilitates the hoisting and relocation of the entire assembly.

[0048] After the two pipe bends 1 are installed, the bends and shipping fixtures are slowly pushed into the container using the bottom sliding plate 32. Depending on the length of the container, two or more sets of fixtures can be used for loading and shipping.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
