Description

Technical Field

[0001] The invention relates to the field of flexible tube transport packaging, and in particular to a flexible tube transport packaging method and a transport packaging device. Background Art

[0002] As a common pipe fitting, flexible pipe is widely used in all walks of life. PE pipe is a common flexible pipe, which is a plastic hose made of monomer ethylene polymerization. It has excellent properties such as good wear resistance, non-toxicity, UV resistance, good flexibility, corrosion resistance and long service life. It is widely used in agricultural irrigation, construction and other fields. According to different specific needs, the diameter of PE pipe is generally between 30 and 100 mm, the wall thickness is between 0.15 and 3 mm, and the length is between 3m and 8m.

[0003] PE pipes need to go through storage, transshipment, and truck transportation after production is completed before they are used by users. Considering the transportation cost, dozens or even hundreds of PE pipes are usually packed into a bundle and then stacked for storage and transportation. This storage and transportation method can easily cause the PE pipes to be squeezed, deformed, and damaged, and there are also problems with transportation such as loading and unloading trucks.

[0004] In order to solve the problem of disorderly storage of PE pipes, a Chinese utility model patent with authorization announcement number CN217620506U and authorization announcement date October 21, 2022 discloses a PE pipe storage device, which includes a base frame, which is rectangular in shape as a whole and is a frame structure. Columns are arranged on the two long sides of the base frame, and the columns correspond one to one in the extension direction of the wide side of the base frame, thereby forming a fence structure on the base frame to enclose a space for storing PE pipes. When in use, the PE pipe can be placed on the base frame, and the PE pipe can be limited by the columns, thereby realizing orderly storage of the PE pipe.

[0005] Although the above-mentioned PE tube storage device can store PE tubes in an orderly manner, since the axial limit of the PE tube is not taken into consideration, when used as a transport package, the PE tube will have axial movement due to inertia during vehicle starting and stopping, thereby causing the flexible tube to scatter. The weight of the stacked PE tubes on the upper PE tubes gradually decreases from bottom to top, so the upper PE tubes are more prone to axial movement. Therefore, there is a need for a packaging method that can maintain the axial stability of the PE tube during transportation and a transport packaging device that can be used to implement the above-mentioned transport packaging method. Summary of the invention

[0006] The purpose of the present invention is to provide a flexible pipe transportation and packaging method to solve the problem that the upper PE pipe is prone to axial movement and dispersion during transportation.

[0007] The present invention also aims to provide a flexible tube transport packaging device to solve the problem that the upper PE tube is prone to axial movement and dispersion during transportation.

[0008] In order to solve the above problems, the flexible tube transportation and packaging method of the present invention adopts the following technical solutions: a flexible tube transportation and packaging method, which is to stack the flexible tubes in groups, and each group of flexible tubes is independently bundled, and the flexible tubes are supported by arranging at least two supporting beams at intervals along the length direction of the flexible tubes at the bottom of the stacked flexible tubes, and the flexible tubes are limited by fixing and connecting limit columns at both ends of the supporting beams, and a supporting cross piece is arranged between two adjacent groups of flexible tubes, and the two ends of the supporting cross piece are respectively connected to two corresponding limit columns on both sides, and at least part of the weight of the flexible tube above it is supported by the supporting cross piece, and each limit column is kept to have a certain amount of swing in the front and rear directions. During transportation, the inertia of the flexible tube is offset by the front and rear swing of the limit column. When the transportation speed is stable, the limit column drives the flexible tube to reset by swinging back.

[0009] Furthermore, the supporting cross member is a supporting cable, which is located higher than the adjacent flexible tube below it when not carrying the flexible tube, and contacts the adjacent flexible tube below it under the action of the gravity of the flexible tube after carrying the flexible tube.

[0010] Furthermore, the supporting cross member is an elastic-plastic metal wire.

[0011] Furthermore, the elastic-plastic metal wire is a low-carbon steel wire with a carbon content of 0.12%-0.22%, a tensile strength of no more than 500 MPa, and an elongation after fracture of no less than 21%.

[0012] Furthermore, each group of flexible pipes is bundled independently and then bundled as a whole at last.

[0013] Furthermore, the supporting cross beam and the limiting column are both made of elastic-plastic material.

[0014] Furthermore, the swing amplitude of each limit column is limited by connecting a longitudinal beam to the top of the limit column located on the same radial side of the flexible tube. A connector that is plugged into and cooperates with the top of the limit column is provided on the longitudinal beam. The distance between the limit columns is limited by plugging the connector into the limit column, and the limit columns are made to swing in coordination.

[0015] Beneficial effects: The flexible tube transportation and packaging method of the present invention is a pioneering invention. By stacking the flexible tubes in groups, the cross piece is used to partially bear the weight of the flexible tube located above, so that the center of gravity of the entire flexible tube being transported can be moved upward. When the transport vehicle starts and stops, the two limit columns will swing under the driving action of the flexible tube, so as to achieve a buffering effect. When the vehicle speed stabilizes, the limit columns will automatically swing back under the action of the gravity of the flexible tube, and at the same time drive the flexible tube to reset in the front and rear directions. It can be seen from the above that the flexible tube transportation and packaging method of the present invention solves the problem of axial movement and dispersion of PE tubes during transportation.

[0016] The flexible tube transport packaging device of the present invention adopts the following technical scheme: the flexible tube transport packaging device includes more than two support frames, each support frame includes a supporting beam and a limiting column fixedly connected to the two ends of the supporting beam, and the supporting beam and the limiting column together form a U-shaped structure; the flexible tube transport packaging device also includes a supporting cross member used to be connected between the two columns of the support frame to support the flexible tube together with the flexible tube below, and the two ends of the supporting cross member are respectively connected to the two corresponding limiting columns on both sides, and the supporting cross member is used to support at least part of the weight of the flexible tube above it, so that each limiting column is kept to have a certain swing amount in the front and rear directions. During transportation, the front and rear swing of the limiting column is used to offset the inertia of the flexible tube. When the transportation speed is stable, the limiting column drives the flexible tube to reset by swinging back.

[0017] Furthermore, it also includes a longitudinal beam for connecting the limit columns located on the same radial side of the flexible tube at the upper end to limit the swing amplitude of each limit column. A connector is provided on the longitudinal beam to cooperate with the top of the limit column. The connector is connected to the limit column to limit the distance between the limit columns and make the limit columns swing in coordination.

[0018] Furthermore, the supporting cross member is an elastic-plastic metal wire.

[0019] Furthermore, the elastic-plastic metal wire is a low-carbon steel wire with a carbon content of 0.12%-0.22%, a tensile strength of no more than 500 MPa, and an elongation after fracture of no less than 21%.

[0020] Furthermore, the supporting cross member is hidden in one of the limiting columns of the supporting frame it matches and is connected to the limiting column through one end.

[0021] Furthermore, the supporting cross beam and the limiting column are both made of elastic-plastic material.

[0022] Furthermore, the flexible tube transport packaging device also includes a flexible tube binding belt.

[0023] Beneficial effects: The flexible tube transport packaging device of the present invention is a pioneering invention. When in use, the flexible tubes can be stacked in groups to support the cross piece to partially bear the weight of the flexible tubes located above, so that the center of gravity of the entire flexible tube being transported can be moved upward. When the transport vehicle starts and stops, the two limit columns will swing under the driving action of the flexible tubes, thereby achieving a buffering effect. When the vehicle speed stabilizes, the limit columns will automatically swing back under the action of the gravity of the flexible tubes, and at the same time drive the flexible tubes to reset in the front and rear directions. It can be seen from the above that the flexible tube transport packaging device of the present invention solves the problem of axial movement and dispersion of PE tubes during transportation.

[0026] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0027] The storage and transportation packaging of the flexible tube 101 will greatly affect the production cost of the manufacturer. In order to save space, the most direct way is to store as many flexible tubes 101 as possible in a limited space and stack them. However, since the flexible tube 101 is different from steel pipes and other pipes, its own strength and hardness are relatively low. For example, for common PE pipes and other flexible pipes, Figure 1 As shown, according to the existing direct stacking method, after stacking, the bottom flexible tube will inevitably be deformed or damaged. In addition, as the stacking height increases, the force on the limit column 102 that limits it will also increase, and the force point will be farther and farther away from the bottom fixed point, and the force arm will increase at the same time. These factors combined will cause the limit column 102 to expand outward. When the expansion reaches a certain degree, the limit column 102 will lose its limiting function, and eventually cause the problem of the flexible tube spreading out.

[0028] In the face of the above problems, the common practice in the prior art is to reduce the force on the bottom flexible tube to prevent it from being crushed by the upper flexible tube, and at the same time limit the limit column 102 to prevent it from tilting and failing; in order to achieve the above purpose, a load-bearing cross piece can be set between the two limit columns 102 to form a layered structure, but when the above method is adopted in the prior art, each limit column will be fixed together in the length direction of the flexible tube to ensure the overall stability. However, after the limit columns are fixed together to form an overall structure, the flexible tube will move relative to the limit column under the action of inertia, which will further cause axial displacement of the flexible tube. The present invention overcomes the technical prejudices in the prior art, such as Figure 8 As shown, each limit column maintains a certain degree of freedom in the front-to-back direction, so that when the flexible tube 101 moves due to inertia, it can drive the limit column 102 to swing back and forth to buffer its movement. After the transportation speed stabilizes, the limit column 102 will automatically reset under the action of the gravity of the flexible tube, thereby ensuring the stability of the transportation process as a whole.

[0029] If a rigid bearing cross piece is used, there may be corresponding problems. First, the contact surface between the rigid bearing cross piece and the flexible tube 101 is small, which will lead to stress concentration at the contact position between the flexible tube 101 and it, and then cause deformation; in addition, the process of disassembly and assembly of the connecting beam will bring inconvenience to the loading and unloading of the flexible tube 101; more importantly, the rigid bearing cross piece will cause the weight of the package to increase sharply, which is obviously not conducive to the control of transportation costs. Therefore, the present invention preferably stacks the flexible tubes 101 in groups and layers, and uses bearing members with a certain deformation ability to partially bear the gravity of the upper flexible tube, and use this gravity to prevent the limit column 102 from expanding outward (such as Figure 2 As shown), the purpose of reliably storing and transporting the flexible pipe 101 without damaging the flexible pipe is achieved.

[0030] Based on the above inventive concept, a basic implementation method of the transport packaging method of the present invention is as follows: Figure 6 , 7 As shown, the method is to stack the flexible tubes 101 in groups, support the flexible tubes 101 by setting a supporting crossbeam 103 at the bottom of the stacked flexible tubes 101, and limit the flexible tubes by connecting limiting columns 102 at both ends of the supporting crossbeam 103. On the one hand, the supporting crossbeam 103 plays the role of combining the two limiting columns 102, and on the other hand, it can be perpendicular to the flexible tube 101 to support the weight of the flexible tube thereon, and leave a certain height at the bottom of the flexible tube 101 to facilitate forklifts and other equipment to pick up the flexible tube thereon. A supporting crosspiece 104 is set between two adjacent groups of flexible tubes, and the two ends of the supporting crosspiece 104 are respectively connected to the two corresponding limiting columns 102 on both sides. The weight of a group of flexible tubes on the supporting crosspiece 104 is shared by the supporting crosspiece 104 and the flexible tubes below it. As shown Figure 2 As shown, here the supporting cross member 104 only bears part of the weight of a group of flexible tubes thereon. Under the gravity of the flexible tubes thereon, the supporting cross member 104 can deform (extend) itself or pull the limit column 102 to deform (approach each other) so that the flexible tubes thereon are supported by the flexible tubes below at the same time, thereby avoiding excessive stress at the contact position between the supporting cross member 104 and the flexible tubes thereon and thus strangling the flexible tubes 101, and also avoiding the gravity of the upper flexible tubes from acting completely on the lower flexible tubes, thereby preventing the bottom flexible tubes from being crushed.

[0031] On the basis of the basic implementation, as a preferred implementation, the supporting cross member 104 is positioned higher than the adjacent flexible tube below it when not carrying the flexible tube, and after carrying the flexible tube 101, it contacts the adjacent flexible tube below under the action of the weight of the flexible tube, which can provide a larger activity space for the supporting cross member 104, so that the supporting cross member 104 can fully play its role. However, in some other implementations, the supporting cross member 104 can also directly contact the flexible tube below in the initial state, and although this will cause the force shared by the flexible tube below the supporting cross member 104 to increase, after the flexible tube 101 is slightly deformed, the supporting cross member 104 will still be able to play the role of sharing the weight of the flexible tube above it.

[0032] On the basis of the basic implementation manner, as a preferred implementation manner, the supporting cross member 104 can be made of a material with certain elastic-plastic properties so that it can actively adapt to the outer contour shape of the flexible tube 101, thereby achieving the effect of further protecting the flexible tube. For example, the supporting cross member can be an elastic-plastic metal wire, specifically a low-carbon steel wire with a diameter of 3 mm, a carbon content of 0.12%-0.22%, a tensile strength of not more than 500 MPa, and an elongation after break of not less than 21%.

[0033] On the basis of the basic implementation mode, as a preferred implementation mode, Figure 6 , 7 As shown, the flexible tubes 101 are divided into two groups and stacked, the flexible tubes in the lower layer are bundled independently, and the flexible tubes in the upper layer are bundled together with the flexible tubes in the lower layer.

[0034] On the basis of the basic implementation, as a preferred implementation, the support beam 103 and the limit column 102 are both made of elastic-plastic materials. This is also to actively adapt to the outer contour of the flexible tube in contact with them, and play a role in further protecting the flexible tube 101. Specifically, the support beam 103 and the limit column 102 can both be rectangular aluminum alloy tubes or rectangular steel tubes.

[0035] When implementing the method of the present invention, multiple supporting beams 103 can be placed at intervals first, and the number and spacing of the supporting beams 103 are selected according to the length of the flexible tube 101. Then, a group of flexible tubes 101 can be placed on the supporting beams 103. The group of flexible tubes can be bundled in advance or bundled after being placed on the supporting beams 103. After the lower layer of flexible tubes are placed, the supporting crosspieces 104 are arranged. The supporting crosspieces 104 can be connected to the limit columns 102 by any detachable connection method such as binding, and then the upper layer of flexible tubes are installed. Finally, all the flexible tubes can be bundled together.

[0036] Figure 3-7 Another embodiment of the packaging method and packaging device of the present invention is given. In this embodiment, in addition to the above-mentioned support beam 103 and the limit column 102 connected to the two ends of the support beam, a longitudinal beam 106 is also included. The longitudinal beam 106 is used to connect the limit columns located on the same radial side of the flexible tube to limit the swing amplitude of each limit column and the spacing X between the limit columns, so that the limit columns can swing in coordination to prevent a certain limit column from having a large swing amplitude or even falling due to the inertia of the flexible tube. The longitudinal beam is provided with a plug-in fitting that plugs in with the top of the limit column. The limit column itself is a rectangular tube structure. The plug-in fitting on the longitudinal beam 106 can be a rectangular tube with a relatively small cross-sectional size, or a solid square steel, which will not be described in detail here.

[0037] When packaging the flexible tube, it can be done in the following two ways.

[0038] The steps of method 1 are as follows: ① First, pre-design the appropriate U-shaped groove (composed of supporting crossbeams and limit columns) and longitudinal beam dimensions according to the diameter and length of the flexible tube to be packaged; ②Assemble the limit column and the longitudinal beam together; ③Put the first group of flexible pipes into bundles and place them into the U-shaped groove, or place the first group of flexible pipes neatly in the U-shaped groove and then put them into bundles; ④Connect and install the supporting cross member; ⑤Put the second set of flexible pipes into bundles and place them in the U-shaped groove or place them neatly in the U-shaped groove directly; ⑥Bundle two or more groups of flexible pipes in the U-shaped groove together.

[0039] The steps of method 2 are as follows: ① Place the supporting beams at intervals according to the length of the flexible pipe; ② Bundle the first set of flexible pipes and place them on the supporting beam; ③ Connect each supporting beam to the limit columns at both ends according to the transverse dimensions of the first group of flexible pipes; ④Match and connect the longitudinal beam and the limit column (or put it in the last step); ⑤Connect and install the supporting cross member; ⑥Put the second set of flexible pipes into bundles and place them in the U-shaped groove or place them neatly in the U-shaped groove directly; ⑦ Bundle two or more groups of flexible pipes in the U-shaped groove together.

[0040] like Fig. 9 As shown, when loading, the two groups of packaged flexible tubes can be transported in a stacked manner.

[0041] As another preferred embodiment of the method of the present invention, Fig.10 As shown, on the basis of the above embodiment, a supporting cross piece 104 can be further provided at the uppermost end of the limiting column and above the flexible tube, and the supporting cross piece 104 plays the role of reinforcing the limiting column here.

[0042] Based on the basic concept of the present invention, the basic implementation method of the transport packaging device of the present invention is as follows: the flexible tube transport packaging device includes more than two support frames, the number of which can be selected according to the length of the flexible tube 101 to be packaged, each support frame includes a support beam 103 and a limit column 102 connected to both ends of the support beam, the support beam 103 and the limit column 102 together form a U-shaped structure, the support beam 103 is used to support the flexible tube 101 placed thereon, and the limit column 102 is used to prevent the flexible tube on the support beam 103 from slipping off from its end; the flexible tube transport packaging device also includes a supporting cross member 104 connected between the two columns of the support frame to support the flexible tube together with the flexible tube below, the function of the supporting cross member 104 is to partially share the gravity of the flexible tube thereon to reduce the pressure on the bottom flexible tube, and at the same time use part of the gravity of the flexible tube thereon to maintain the upright posture of the limit column 102 to prevent it from expanding outward; Figure 8 As shown, during the transportation process, if the transportation speed changes suddenly, the limit column will swing under the drive of the flexible tube, thereby buffering the movement of the flexible tube. When the transportation speed stabilizes, the limit column will automatically reset under the action of the gravity of the flexible tube.

[0043] On the basis of the basic implementation, as a preferred implementation, the supporting cross member 104 is an elastic-plastic metal wire, specifically a steel wire rope or iron wire, which is not only easy to obtain, but also low in cost and extremely light in weight. The advantages of adopting the above means can be referred to the implementation of the transport packaging method of the present invention, which will not be described in detail here.

[0044] Based on the basic implementation, as a preferred implementation, the supporting cross member 104 is hidden in one of the limiting columns 102 of the supporting frame and connected to the limiting column through one end. This method can facilitate the arrangement of the supporting cross member 104 when in use. Its specific structure can refer to the structure of the currently commercially available hidden clothesline, which will not be described in detail here.

[0045] On the basis of the basic implementation, as a preferred implementation, the support beam 103 and the limit column 102 are both made of elastic-plastic materials. Specifically, they can be rectangular aluminum alloy tubes or rectangular steel tubes. They not only have the required strength, but also can actively adapt to the outer contour of the flexible tube, playing a role in further protecting the flexible tube.

[0046] On the basis of the basic implementation, as a preferred implementation, the support beam 103 and the limiting column 102 are movably connected in the length direction of the support beam to adjust the distance between the two limiting columns. This structure can make the transport packaging device of the present invention suitable for packaging of different numbers of flexible tubes. Regarding the structure of the plug-in, for example, a plug rod perpendicular to the bottom of the limiting column can be provided, and the plug rod can be inserted into the socket provided at the end of the support beam, or a hole can be directly opened on the limiting column, and the support beam can be inserted into the hole of the limiting column. There are many ways to implement it, which will not be described here.

[0047] On the basis of the basic implementation, as a preferred implementation, the flexible tube transport packaging device further includes a flexible tube strapping belt 105. The directly matched strapping belt can further facilitate the packaging of the flexible tube. Specifically, the strapping belt can be a common plastic steel strapping belt, iron wire, elastic rope, etc., which will not be described in detail here.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
