Description

Technical Field

[0001] The present invention relates to the technical field of large part transportation, and particularly to a packing and shipping tool for large-diameter elbows. Background Art

[0002] When large-diameter pipes are shipped in containers, the pipes must be fixed in the container to avoid problems such as collision between the pipes due to radial or axial displacement during transportation.

[0003] For large-diameter elbows during packing and shipping, due to their irregular shapes, they are generally fixed with wooden pallets or pads, and rubber pads are used to isolate and protect between multiple elbows, or multi-layer straight shelves are used for fixation; currently, for large-diameter elbows, wooden pallets and pads are generally used for fixation, and rubber pads are used to isolate and protect between multiple elbows. During transportation or transshipment, problems such as collision between pipes and damage to the paint on the surface of the elbows may occur due to improper protection, which is likely to cause customer complaints. Moreover, when loading into the container, they need to be loaded one by one, resulting in low work efficiency; if multi-layer straight shelves are used for fixation, although this method can avoid collisions, it occupies a large space, has a low space utilization rate when loading into the container, and has a high transportation cost.

[0004] In the prior art, as disclosed in CN113247469B, there is a portable pipe support assembly for a tank container, including a storage tank and a container frame formed around the storage tank. A laterally opening support plate for supporting and accommodating pipes is adjustably installed on the side of the container frame. A loading substrate for installing the laterally opening support plate is provided on the side of the container frame. The laterally opening support plate is hingedly installed with the loading substrate. A driving member is provided on one side of the loading substrate away from the installation position of the laterally opening support plate. The driving member drives the laterally opening support plate to rotate around the position where the laterally opening support plate is hinged with the loading substrate. An extendable bearing member is provided below the loading substrate, and the bearing member cooperates with the driving member to support the laterally opening support plate in a horizontal state. This structure is used to fix the storage tank, and the storage tank is a large-diameter pipe with end plugs. Although this structure can fix the large-diameter storage tank well, this structure can only fix a single large-diameter pipe. When the cross-section of the container can accommodate multiple large-diameter pipes, using this fixing method will inevitably cause huge space waste, and this fixing structure is not convenient for removing the pipes from the rack; secondly, this structure is not convenient for fixing elbows either.

[0005] In view of the above, it is necessary to propose a packing and shipping tool for large-diameter elbows to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a packing and shipping tool for large-diameter elbows, which overcomes the defects existing in the prior art.

[0007] To achieve the above object, the technical solution of the present invention is as follows: A packing and shipping tooling for large-diameter elbows. The tooling frame body includes a bottom frame body and a supporting vertical frame. The supporting vertical frame is vertically fixed on the bottom frame body, and the width of the bottom frame body matches the internal width of the container. The elbow pipe fittings are fixed on the tooling frame body in a combination of two pieces as a group. The elbow parts of the two elbow pipe fittings are respectively placed at both ends of the tooling frame body, and the straight pipe parts are arranged in a staggered manner in the longitudinal direction. The supporting vertical frame forms a supporting foundation for the elbow pipe fittings located on the upper side, and the bottom frame body forms a supporting foundation for the elbow pipe fittings located on the lower side. The two end regions of the tooling frame body form elbow fixing areas, and the straight pipe fixing area is between the two elbow fixing areas.

[0008] Further, the bottom frame body is in a rectangular frame structure and includes a first cross beam and a second cross beam. There are at least two first cross beams and they are arranged parallel to each other. A plurality of second cross beams are vertically arranged between the first cross beams, and both ends of the second cross beams are respectively fixedly connected to the first cross beams.

[0009] Further, the elbow fixing area at least includes two second cross beams parallel to each other. The inner second cross beam forms the positioning of the flange at the end of the straight pipe section, and the outer second cross beam forms the positioning of the flange of the elbow part.

[0010] Further, at least one of the inner second cross beams is provided with a supporting vertical frame. The supporting vertical frame includes a first strut, a second strut, and a cross frame rod. The upper parts of the first strut and the second strut are fixedly provided with a cross frame rod. The lower ends of the first strut and the second strut are vertically fixed on an inner second cross beam. The first strut is arranged close to one side of the first cross beam, and diagonal struts are provided between both sides of the first strut and the first cross beam.

[0011] Further, one end of the bottom frame body is provided with an inclined baffle plate that fits the end face of the flange.

[0012] Further, the first cross beam is a structure with adjustable length.

[0013] Further, sliding plates are provided on the supporting feet of the lower end face of the bottom frame body.

[0014] A method for using a packing and shipping tooling for large-diameter elbows includes the following steps: S1. According to the length of the elbow pipe fittings, adjust the length of the first cross beam to adjust the length of the bottom frame body to a suitable position. S2. Preset through holes corresponding to the flange holes on the third crossbeam and the inclined baffle plate. First, place the horizontally placed elbow on the bottom frame. Align the flange of the straight pipe end with the position of the through hole and insert bolts for fixation.

Insert bolts through the through holes of the flange and the inclined baffle plate for fixation; S3. Preset through holes corresponding to the flange holes on the fourth crossbeam and the horizontal crossbar. Vertically position the vertically placed elbow on the fourth crossbeam and the horizontal crossbar. Insert bolts through the through holes on the fourth crossbeam and the horizontal crossbar corresponding to the flanges at both ends for fixation; S4. Fill rubber pads between the two elbows for fixation to provide double protection; S5. Weld lifting lug plates at appropriate positions on the bottom frame.

[0017] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0018] Embodiment 1: The large-diameter elbow pipe fitting 1 in the present invention is in an L shape, having a straight pipe portion 2 and a bent head portion 3. A short bent head portion 3 is connected to one end of the straight pipe portion 2, and flange plates 4 are provided at both ends of the large-diameter elbow pipe fitting 1. According to the specific shape of the above workpiece, a large-diameter elbow packing and shipping tooling is made, as Figures 1-5 shown. The overall tooling is a pallet frame structure, and materials such as square steel pipes, H-shaped steel, C-shaped steel or L-shaped steel can be selected and cut to form the entire tooling frame. The tooling frame specifically includes a bottom frame 5 forming a bottom pallet at the bottom, and a support vertical frame 6 vertically arranged on the bottom frame 5. When manufacturing, the width of the bottom frame 5 is matched with the inner width of the container; thus, it is convenient to put the fixed pipe fittings together with the tooling into the container. It can be understood that the use scope of this tooling is not limited to containers, and can also be in cuboid transportation equipment such as trucks and railway carriages; The elbow pipe fittings 1 are fixed on the tooling frame in a combination of two pieces as a group, as Figure 1 shown. The bent head portions 3 of the two elbow pipe fittings 1 are respectively placed at both ends of the tooling frame. Since the diameter of the elbow pipe is large, if only one elbow pipe is fixed in each container, more space will be wasted. Considering making full use of the space in the container, in this embodiment, the two elbow pipes are placed in a staggered layer, one elbow pipe is located on the lower side, and the other elbow pipe is located obliquely above, so that the two elbow pipes are as Figure 4 shown in the cross section, and the straight pipe portions 2 of the elbow pipes are arranged in a staggered manner in the longitudinal direction; thus, more large-diameter elbow pipe fittings 1 can be loaded into the limited container space.

[0019] Specifically, as Figure 1 、 4 shown, the support vertical frame 6 forms a support foundation for the elbow pipe fitting 1 located on the upper side, and the bottom frame 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 form elbow fixing areas 7, and a straight pipe fixing area 8 is between the two elbow fixing areas 7. Since the bent head portion 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 areas 7, and the two straight pipe portions 2 are both fixed in the straight pipe fixing area 8.

[0020] Specifically, the bottom frame body 5 is in a rectangular frame structure and includes a first cross beam 9 and a second cross beam 10. There are at least two first cross beams 9 and they are arranged in parallel. A plurality of second cross beams 10 are vertically arranged between the first cross beams 9, and both ends of the second cross beams 10 are fixedly connected to the first cross beams 9 respectively. In this embodiment, as Figure 2 shown, there are two first cross beams 9, and four second cross beams 10 are successively arranged between the two first cross beams 9, forming a structure in the shape of a Chinese character "mu". Specifically, the second cross beams 10 are successively divided into cross beam one 24, cross beam two 25, cross beam three 26, and cross beam four 27.

[0021] The elbow fixing area 7 includes at least two second cross beams 10 that are parallel to each other. Specifically, an elbow fixing area 7 is formed between cross beam one 24 and cross beam two 25, and another elbow fixing area 7 is formed between cross beam three 26 and cross beam four 27; 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 、 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 elbow part 3, that is, the elbow part 3 of the horizontally placed elbow pipe 29 is located in the elbow fixing area 7 between cross beam one 24 and cross beam two 25. As Figure 1 、 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 elbow part 3 as the standard. When the elbow part 3 is placed horizontally, it is defined as the horizontally placed elbow pipe 29, and when the elbow part 3 is placed vertically, it is positioned as the vertically placed elbow pipe 30; it can be understood that the flange 4 at the elbow end of the horizontally placed elbow pipe 29 can have a certain inclination angle, as Figure 1 shown; then in order to adapt to the fixing of the inclined flange 4, a slanting baffle 15 is correspondingly arranged 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 shown, a connecting beam 28 is vertically arranged between cross beam one 24 and cross beam two 25, and a slanting baffle 15 that fits the inclined flange 4 is fixedly arranged on cross beam one 24 and the connecting beam 28; one side of the slanting baffle 15 can be used for clamping and limiting, and the other side can be assembled and connected with the flange 4 to form a fixation. Specifically, as Figure 4 shown, a through hole 23 corresponding to the flange 4 is opened on the slanting baffle 15, and bolts are used to pass through the through hole 23 and the flange 4 to lock and fix.

[0022] Furthermore, a support stand 6 is arranged on at least one of the inner second cross beams 10, as Figure 2 、 3, as shown in FIG. 4, the support vertical frame 6 includes a first support rod 11, a second support rod 12, and a cross frame rod 13. The upper parts of the first support rod 11 and the second support rod 12 are fixedly provided with the cross frame rod 13. The lower ends of the first support rod 11 and the second support rod 12 are vertically fixed on a second cross beam 10 on the inner side. The first support rod 11 is arranged close to the first cross beam 9 on one side. Diagonal support rods 14 are provided between both sides of the first support rod 11 and the first cross beam 9. The cross frame rod 13 is lifted by the first support rod 11 and the second support rod 12 and is located above the second cross beam 25. The strengthening fixation is formed by the diagonal support rods 14 arranged on both sides to avoid shaking and displacement; when fixing the large-diameter elbow pipe fitting 1, such as Figure 1 , 4 , as shown in FIG., through holes 23 matching with the flange 4 are also provided on the cross frame rod 13. The flange 4 of the straight pipe part 2 is attached to the cross frame rod 13, and bolts are also inserted to fix this end. While the flange 4 at the other end can be buckled on the fourth cross beam 27. Similarly, through holes 23 are also provided on the fourth cross beam 27. After locking and fixing the flange 4 and the through holes 23, the fixation of the two elbow pipe fittings 1 is completed.

[0023] Embodiment 2: The structure of this embodiment is generally the same as that of Embodiment 1, the difference being that the length of the bottom frame body 5 in this embodiment can be adjusted. Specifically, the first cross beam 9 is a structure with adjustable telescopic length; in actual use, the first cross beam 9 can be divided into two mutually sleeved sections, so that the length can be changed by telescoping. Then, a plurality of adjustment holes 31 are provided at the joint part of the cross beam. Fixing bolts are inserted into the adjustment holes 31. When the length needs to be changed, only need to loosen the fixing bolts, then adjust the length of the first cross beam 9, align the adjustment holes 31, and then insert the fixing bolts, such as Figure 1 shows schematic diagrams of two bottom frame bodies 5 with different lengths and fixing large-diameter elbow pipe fittings 1 with different lengths.

[0024] Furthermore, sliding plates 32 are provided on the support feet on the lower end surface of the bottom frame body 5. The sliding plates 32 are installed at the bottom of the entire tooling frame body and can smoothly enter when the whole is loaded into the container.

[0025] A method for using a large-diameter elbow pipe packing and shipping tooling includes the following steps: S1. According to the length of the elbow pipe fitting 1, adjust the length of the first cross beam 9 and adjust the length of the bottom frame body 5 to a suitable position; specifically, loosen the fixing bolts, then adjust the length of the first cross beam 9, align the adjustment holes 31, and then insert the fixing bolts; the advantage is that it can be telescopically adjusted according to the length of different loaded goods and fixed with locking bolts after adjustment in place.

[0026] S2. On the third crossbeam 26 and the inclined baffle 15, through holes 23 corresponding to the hole positions of the flange 4 are preset. First, place the flat elbow 29 on the bottom frame 5. The straight pipe end flange 4 corresponds to the position of the through hole 23 and bolts are inserted through and fixed. Position the inclined baffle 15 according to the position of the elbow end flange 4 and weld it to the bottom frame 5. Insert bolts through the through holes 23 of the flange 4 and the inclined baffle 15 for fixation; the positions of the through holes 23 are drilled according to the installation positions of different elbows, so as to achieve high-precision adaptation. S3. On the fourth crossbeam 27 and the horizontal frame rod 13, through holes 23 corresponding to the hole positions of the flange 4 are preset. Position the vertical elbow 30 vertically on the fourth crossbeam 27 and the horizontal frame rod 13. The flanges 4 at both ends respectively correspond to the through holes 23 on the fourth crossbeam 27 and the horizontal frame rod 13, and bolts are inserted through for fixation; similar to step two, use the through holes 23 and the flange 4 for fixation, so as to fix the large-diameter elbow.

[0027] S4. Fill rubber pads between the two elbows for fixation to provide double protection; steel wires can also be pulled for fixation.

[0028] S5. Weld lifting lug plates at appropriate positions on the bottom frame 5. It is convenient to hoist and transfer the whole.

[0029] After the two elbow pipe fittings 1 are installed, slowly push the elbow and the shipping tooling frame into the container by using the bottom slide plate 32. According to the length of the container, two groups or multiple groups of toolings can be combined for packing and shipping.

[0030] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
