Description

TECHNICAL FIELD

[0001] The utility model relates to the workshop storage device convenient to store, take work piece, tool or instrument, especially relate to a kind of flexible pipe packaging device. BACKGROUND

[0002] Flexible pipe is widely used by various industries as a common pipe. PE pipe is a common flexible pipe, which is a plastic hose polymerized by monomer ethylene, has good wear resistance, non-toxic, anti-ultraviolet, good flexibility, corrosion resistance and long service life, and is widely used in agricultural irrigation, construction and other fields. According to different specific needs, the pipe diameter of PE pipe is generally between 30-100mm, the wall thickness is between 0.15-3mm, and the length is between 3m-8m.

[0003] After production, PE pipe needs to go through storage, transfer, truck transportation and other processes before use. 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 is prone to cause extrusion deformation and damage of PE pipe, and also has the problem of inconvenient transfer such as loading and unloading.

[0004] In order to solve the problem of disordered storage of PE pipe, a PE pipe storage device is disclosed in Chinese Utility Model Patent No. CN217620506U, authorized on October 21, 2022, which includes a chassis. The chassis is in the shape of a rectangle and is in the form of a frame structure. On both long sides of the chassis, there are vertical columns that correspond one by one in the extension direction of the wide side of the chassis, forming a fence structure on the chassis to enclose a space for storing PE pipes. When in use, PE pipes can be placed on the chassis and limited by vertical columns to achieve orderly storage of PE pipes.

[0005] Although the above-mentioned PE pipe storage device can store PE pipes in order, it still has the problem of crushing the bottom layer of PE pipe by the upper layer of PE pipe. In addition, when the number of stacked PE pipes is large and the weight is heavy, the PE pipes will disperse to both sides, thereby exerting an external force on the vertical columns to make them tilt outward. The influence of this force is not obvious when the PE pipe is stored statically, but when the PE pipe storage device is used as a transportation package, it will be extremely likely to cause the vertical columns to be bent or even broken under the influence of road bumps, so the above-mentioned PE pipe storage device cannot meet the demand of being used as a transportation package. UTILITY MODEL CONTENTS

[0006] The utility model aims to provide a flexible pipe packaging device to solve the problem of easy damage and poor reliability during storage and transportation of PE pipe.

[0007] To solve the above problems, the flexible pipe packaging device adopts the following technical scheme: the flexible pipe packaging device comprises two or more support frames, each support frame comprises a support beam and a limiting column connected to two ends of the support beam, and the support beam and the limiting column together form a U-shaped structure; the flexible pipe packaging device further comprises a supporting cable connected between the two columns of the support frame to support the flexible pipe together with the flexible pipe below.

[0008] Further, the supporting cable is an elastic-plastic metal wire.

[0009] Further, the elastic-plastic metal wire is a low-carbon steel wire with a carbon content of 0.12%-0.22%, a tensile strength of not more than 500 MPa, and an elongation after fracture of not less than 21%.

[0010] Further, the supporting cable is hidden in one of the limiting columns of the support frame it cooperates with and is connected to the limiting column through one end.

[0011] Further, the support beam and the limiting column are both made of an elastic-plastic material.

[0012] Further, the support beam and the limiting column are movably inserted in the length direction of the support beam to adjust the distance between the two limiting columns.

[0013] Further, the flexible pipe packaging device further comprises a flexible pipe binding belt.

[0014] Beneficial effects: The flexible pipe packaging device is an opening invention, which can group and stack the flexible pipes when used, so that the weight of the flexible pipes above is shared by the supporting cables and the flexible pipes below, thereby avoiding the continuous and large-scale accumulation of the weight of the bottom flexible pipes, achieving the effect of preventing the bottom flexible pipes from being deformed or damaged by pressure; in addition, since the supporting cable is connected between the two limiting columns when used, it can also limit the limiting column with the weight of the flexible pipe, preventing the top of the limiting column from expanding outward, thereby improving the reliability during storage and transportation. In summary, the flexible pipe packaging device can solve the problems of easy damage and poor reliability of PE pipes during storage and transportation. BRIEF DESCRIPTION OF DRAWINGS

[0020] The features and performance of the present application will be further described in detail below in conjunction with the embodiments.

[0021] The storage packaging and transportation packaging of the flexible pipe 101 will greatly affect the production cost of the manufacturer. In order to save space, the flexible pipe 101 is stacked as much as possible in a limited space, which is the most direct method. However, since the flexible pipe 101 is different from the pipe fittings such as steel pipes, its own strength and hardness are low. For example, as shown in FIG. Figure 1 According to the existing direct stacking method, the bottom flexible pipe will inevitably be deformed or damaged after stacking. In addition, as the stacking height increases, the force borne by the limiting column 102 for limiting will also increase, and the distance from the stress point to the bottom fixed point becomes farther and farther away, and the force arm also increases. These factors will cause the limiting column 102 to expand outward, and when it expands to a certain extent, the limiting column 102 will lose its limiting effect, eventually causing the flexible pipe to spread out.

[0022] In the face of the above problems, the common practice in the prior art is to expect to avoid the bottom flexible pipe from being crushed by the upper flexible pipe by reducing the stress of the bottom flexible pipe, and to limit the position of the limiting column 102 to avoid its tilting and failure. In order to achieve the above purpose, the most direct way is to set a connecting beam between the two limiting columns 102 to form a layered structure, but if the above method is used, a new problem will be faced, which is that the contact surface between the rigid connecting beam and the flexible pipe 101 is small, which will cause stress concentration at the contact position of the flexible pipe 101, thereby causing deformation. In addition, the disassembly and assembly process of the connecting beam will bring inconvenience to the loading and unloading of the flexible pipe 101. More importantly, the rigid connecting beam will cause the weight of the package to rise sharply, which is obviously not conducive to the control of transportation cost. Therefore, the present application proposes a completely new invention concept, which groups and stacks the flexible pipes 101, uses a bearing member that can have a certain deformation capacity, partially bears the gravity of the upper flexible pipe, and uses the gravity to prevent the limiting column 102 from expanding outward, thereby achieving the purpose of reliably storing and transporting the flexible pipe 101 without damaging the flexible pipe.

[0023] Based on the above utility model concept, the present application can use the following method to package the flexible pipe: as shown in Figure 2 、 4 The method is to group and stack the flexible pipes 101, support the flexible pipes 101 by setting a support beam 103 at the bottom of the stacked flexible pipes 101, and limit the flexible pipes by connecting limiting columns 102 at both ends of the support beam 103. The support beam 103 plays a role in combining the two limiting columns 102, and can be perpendicular to the flexible pipes 101 to support the weight of the flexible pipes above, and leave a certain height at the bottom of the flexible pipes 101 to facilitate the lifting of the flexible pipes by a forklift or other equipment. A supporting cable 104 is provided between the two adjacent groups of flexible pipes, and the supporting cable 104 is connected to the corresponding two limiting columns 102 on both sides at both ends. The weight of a group of flexible pipes on the supporting cable 104 is shared by the supporting cable 104 and the flexible pipes below. Here, the supporting cable 104 only bears part of the weight of the flexible pipes above, and under the action of the gravity of the flexible pipes above, the supporting cable 104 can deform (stretch) or pull the limiting column 102 to deform (move closer to each other) to allow the flexible pipes above to be supported by the flexible pipes below, thereby avoiding the supporting cable 104 from being damaged by the excessive stress at the contact position between the supporting cable 104 and the flexible pipes above, and also avoiding the gravity of the upper flexible pipe from acting entirely on the lower flexible pipe, thereby preventing the bottom flexible pipe from being crushed.

[0024] As an improvement to the above method, the supporting cable 104 is higher than the adjacent flexible pipe below it when not bearing the flexible pipe, and after bearing the flexible pipe 101, it is in contact with the adjacent flexible pipe below it under the gravity of the flexible pipe, which can provide more space for the supporting cable 104 to fully play its role. However, in other embodiments, the supporting cable 104 can also be in contact with the flexible pipe below it in the initial state, which may result in a larger force shared by the flexible pipe below the supporting cable 104, but after the flexible pipe 101 is deformed slightly, the supporting cable 104 will still be able to share the gravity of the flexible pipe above it.

[0025] As an improvement to the above method, the supporting cable 104 can be made of a certain elastic-plastic material to actively adapt to the outer shape of the flexible pipe 101, achieving the effect of further protecting the flexible pipe. For example, the supporting cable 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 fracture of not less than 21%.

[0026] As an improvement to the above method, the flexible pipes 101 are divided into two groups and stacked, and the flexible pipes in the lower group are independently bundled, while the flexible pipes in the upper group are bundled together with the flexible pipes in the lower group.

[0027] As an improvement to the above method, the supporting beam 103 and the limiting column 102 are both made of elastic-plastic material. This is also to actively adapt to the outer shape of the flexible pipe in contact with it, and to further protect the flexible pipe 101. Specifically, the supporting beam 103 and the limiting column 102 can both be rectangular aluminum alloy pipes or rectangular steel pipes.

[0028] When implementing the above method, as shown in Figure 3 , a plurality of 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 pipe 101. Then, a group of flexible pipes 101 is placed on the supporting beams 103, which can be bundled in advance or after being placed on the supporting beams 103. After the lower flexible pipes are placed, the supporting cable 104 is arranged, which can be connected to the limiting column 102 by any detachable connection method such as binding. Then, the upper flexible pipes are installed, and finally, all the flexible pipes are bundled together.

[0029] Based on the basic idea of the utility model, the basic implementation mode of the packaging device is as follows: the flexible pipe packaging device comprises two or more support frames, the number of the support frames can be selected according to the length of the flexible pipe 101 to be packaged, each support frame comprises a support beam 103 and a limiting column 102 connected to both ends of the support beam, the support beam 103 and the limiting column 102 together form a U-shaped structure, the support beam 103 is used for supporting the flexible pipe 101 placed thereon, and the limiting column 102 is used for preventing the flexible pipe on the support beam 103 from slipping off from the end thereof; the flexible pipe packaging device further comprises a supporting rope 104 used for being connected between the two vertical columns of the support frame to support the flexible pipe together with the flexible pipe below, the supporting rope 104 is used for partially sharing the gravity of the flexible pipe thereon to reduce the pressure on the bottom flexible pipe, and the partial gravity of the flexible pipe thereon is used for maintaining the vertical posture of the limiting column 102 to prevent the limiting column 102 from expanding outward.

[0030] On the basis of the basic implementation mode, as a preferred implementation mode, the supporting rope 104 is a elastoplastic metal wire, specifically a steel wire rope or an iron wire, which is easy to obtain and low in cost and extremely light in weight.

[0031] On the basis of the basic implementation mode, as a preferred implementation mode, the supporting rope 104 is hidden in one of the limiting columns 102 of the support frame matched with the supporting rope 104 and is connected to the limiting column at one end. This mode can facilitate the arrangement of the supporting rope 104 in use, and the specific structure thereof can refer to the structure of a currently marketed hidden clothesline, and details are not described herein.

[0032] On the basis of the basic implementation mode, as a preferred implementation mode, the support beam 103 and the limiting column 102 are both made of an elastoplastic material. Specifically, they can both be rectangular aluminum alloy pipes or rectangular steel pipes. They not only have a required strength, but also can actively adapt to the outer contour of the flexible pipe to further protect the flexible pipe.

[0033] On the basis of the basic implementation mode, as a preferred implementation mode, the support beam 103 and the limiting column 102 are movably inserted in the length direction of the support beam to adjust the distance between the two limiting columns. This structure can make the packaging device of the utility model applicable to the packaging of different numbers of flexible pipes. As to the structure of the insertion part, for example, an insertion rod perpendicular to the limiting column can be arranged at the bottom of the limiting column and inserted into an insertion hole arranged at the end of the support beam, or a hole can be directly arranged on the limiting column, and the support beam is inserted into the hole of the limiting column, and there are various implementation modes, and details are not described herein.

[0034] On the basis of the basic embodiment, as a preferred embodiment, the flexible tube packaging device further comprises a flexible tube bundling belt 105. The directly matched bundling belt can further facilitate the packaging of the flexible tube, and specifically, the bundling belt can adopt common plastic steel packing belt, iron wire, elastic rope, etc., which will not be described here.

[0035] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. The patent protection scope of the present application is subject to the claims, and any equivalent structural changes made by referring to the content of the specification and drawings of the present application should also be included in the protection scope of the present application.
