Pipe storage rack

Abstract

This invention relates to a pipe storage rack, designed to address the technical problems of existing similar products that rarely use two symmetrically combined units, resulting in large volume, inconvenience in handling and relocation, difficulty in layering pipes during stacking, limited storage height, and limited structural forms and usage methods. The main frame on one rear side of this pipe storage rack is rectangular. Symmetrically arranged upper and lower sub-frames are located at the upper and lower ends of the front side of the main frame. The upper and lower sub-frames are connected to the main frame by connecting rods, forming a symmetrical cuboid frame structure. A storage gap is provided between the upper and lower sub-frames. The key feature is that the connecting rods on one side of the upper and lower sub-frames are omitted, creating an open frame structure. Pipes are placed between the two symmetrically arranged frames on the open side, or between two frames opposite each other. Reinforcing rods are provided on the main frame, upper sub-frame, and lower sub-frame corresponding to the connecting rods.

Description

Technical Field

[0001] This invention relates to storage racks, specifically a tubular storage rack. Background Technology

[0002] Storage racks are shelves used for storing and retrieving items. Some factories and construction sites currently use storage racks for stacking large, long pipes. They are mainly made of reinforced square tubing, and some have upper and lower layer designs or are used in combination on both sides. Examples include Chinese patent application number 201420478038.5, authorized on February 18, 2015, entitled "Pipe Stacking Rack"; and Chinese patent application number 201921720449.X, authorized on August 25, 2020, entitled "A Cable Protection Pipe Storage Rack." These products and similar products are generally used independently, rarely in a symmetrical combination. They are relatively large, making handling and relocation inconvenient, and layering when stacking pipes is difficult, with limited storage height. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a pipe storage rack that addresses the technical problems of existing similar products, such as the limited use of two symmetrical combinations, large size, inconvenience in handling and relocation, difficulty in layering pipes during stacking, limited storage height, and relatively simple structural forms and usage methods. This objective is achieved through the following technical solution.

[0004] A pipe storage rack has a rectangular main frame on one rear side. Symmetrically arranged upper and lower sub-frames are located at the upper and lower ends of the front side of the main frame. The upper and lower sub-frames are connected to the main frame via connecting rods, forming a symmetrical cuboid frame structure. A storage gap is provided between the upper and lower sub-frames. The key structural design feature is that the connecting rods on one side of the upper and lower sub-frames are omitted, creating an open frame structure. Pipes are placed between two symmetrically arranged frames on the open side, or between two frames opposite each other. Reinforcing rods are provided on the main frame, upper sub-frames, and lower sub-frames corresponding to the connecting rods. The reinforcing rods are arranged on the plane of the main frame, upper sub-frames, and lower sub-frames. Connecting rods are provided between the main frame and the upper and lower sub-frames. Two main frames are used symmetrically arranged on one open side, or two main frames are used opposite each other via the upper and lower sub-frames. Besides these two symmetrical usage methods, they can also be used individually, in multiple sets, or placed on other sides as needed.

[0005] The upper and lower sub-frames of the frame are respectively square or rectangular frame structures. The above are specific structural embodiments of the upper and lower sub-frames.

[0006] The upper subframe and lower subframe are respectively equipped with reinforcing rods near their bottoms, which correspond to the connecting rods between the main frame and the upper and lower subframes. This structure further enhances the stability and robustness of the main frame, upper subframe, and lower subframe.

[0007] The connecting rods at the top and bottom of the main frame, upper sub-frame, and lower sub-frame of the rack are respectively located in the middle. This structure reduces costs and also allows the pipe storage rack to be used independently with the open side facing upwards when inverted.

[0008] The connecting rod at the bottom between the main frame and the lower sub-frame of the structure has been replaced with a base plate. This structure further enhances the gravity and stability of the bottom.

[0009] The bottom of the frame has two symmetrically arranged supports, which are "E" shaped. Connecting rods, symmetrically arranged on at least two sides of the bottom of the frame, are respectively snapped into the protruding snap grooves on the top of the supports. Forklift holes are provided at both ends of the supports. This facilitates the handling of the pipe storage rack by lifting the supports with a forklift. The supports adopt the structural design of the following specific embodiment.

[0010] The support is a plastic part formed in one piece by blow molding, and a raised reinforcing rib is provided horizontally in the middle of the top plane of the support. The support made by the above method and structure is low in cost and has good sturdiness.

[0011] The bracket's snap-fit ​​groove or snap-fit ​​is fixed to the tray with fixing holes. The bracket's snap-fit ​​groove and the tray's fixing holes are integrated. The top of the tray has a rod groove or bottom groove that facilitates the placement of the bottom of the frame and corresponds to the connecting rod. The above-described bracket and tray combination structure makes the bottom more stable.

[0012] The upper and lower sub-frames of the frame are equipped with side plates on one side, or the main frame of the frame is equipped with side plates. This facilitates the flat and aligned placement of the pipe ends.

[0013] The present invention has a reasonable structural design, is easy to manufacture and use, and has various forms and methods of use. When used symmetrically, it is convenient to stack pipes in upper and lower layers. It is suitable for use as a pipe storage rack and for structural improvements of similar products.

[0019] Now, in combination with the attached drawings, the structure and use of the present invention will be further described. As Figure 1 shown in Embodiment 1, the main frame 101 at the rear side of one side of the frame 1 of this pipe storage rack is rectangular. The upper and lower ends of the front side of the main frame are symmetrically provided with an upper sub-frame 102 and a lower sub-frame 103 respectively. The upper sub-frame and the lower sub-frame are respectively connected to the main frame by connecting rods 105 to form a vertically symmetric rectangular parallelepiped frame structure, and a storage gap is provided between the upper sub-frame and the lower sub-frame. Its specific structure is as follows: the upper sub-frame and the lower sub-frame of the above-mentioned frame are of an open-frame structure with the connecting rods omitted on one side. The pipes are arranged between two frames symmetrically arranged on the open side, the pipes are arranged between two frames where the upper sub-frame and the lower sub-frame are oppositely arranged, and the main frame, the upper sub-frame and the lower sub-frame corresponding to the connecting rods are respectively provided with reinforcing rods 106; the reinforcing rods are specifically arranged near the top of the upper sub-frame and the bottom of the lower sub-frame of the frame, the reinforcing rods correspond to the connecting rods arranged between the main frame and the upper sub-frame and the lower sub-frame, and the upper sub-frame and the lower sub-frame of the frame are respectively of a square frame structure; a bottom plate 104 is also provided on the connecting rod at the bottom between the main frame and the lower sub-frame of the frame, and the connecting rod at the bottom plate can also adopt a "field" - shaped structure; the connecting rods at the top and bottom between the main frame and the upper sub-frame and the lower sub-frame of the frame are respectively arranged in the middle.

[0020] According to the above structural characteristics, as Figure 2 shown in Embodiment 2, the bottom plate structure at the bottom is omitted in the figure. As Figure 3 shown in Embodiment 3, the reinforcing rods are respectively omitted in the upper sub-frame, the lower sub-frame and the main frame. Except for the connecting rods in the middle, connecting rods are respectively provided at the outer ends between the top and bottom of the main frame and the upper sub-frame and the lower sub-frame to ensure the stability of its frame structure.

[0021] When in use, the open sides of the frames of two such pipe storage racks are symmetrically arranged. The pipes are placed in the gap between the main frame and the lower sub-frame that limits the scattering of the pipes. The longer pipes extend out of the upper sub-frames on both sides of the frame and are placed on the upper-layer upper sub-frames. Or the pipes are arranged between two frames where the upper sub-frame and the lower sub-frame are oppositely arranged, and the pipes are respectively arranged in the lower sub-frame or the upper sub-frame in the upper and lower layers. In order to prevent the pipes from being damaged outdoors, top covers are respectively arranged at the tops between the two main frames. At the same time, in order to place the ends of the pipes more neatly, side plates are provided on one side of the upper sub-frame and the lower sub-frame of the above-mentioned frame, or side plates are provided on the main frame of the frame.

[0022] As Figure 4 In the fourth embodiment shown, connecting rods are provided on both sides of the bottom between the main frame and the upper and lower sub-frames of the frame. Two symmetrically arranged support seats 2 are provided at the bottom of the frame, each in an "E" shape. The connecting rods on both sides of the bottom of the frame are respectively snapped into the protruding snap-fit ​​grooves 201 on the top of the support seats. Forklift holes 202 are provided at both ends of the support seats. The support seats are plastic parts formed in one piece by blow molding, and a raised reinforcing rib 203 is provided laterally in the middle of the top plane of the support seat. Based on the structural features of the fourth embodiment, the snap-fit ​​grooves or snaps of the support seats are fixed to a pallet with fixing holes. The snap-fit ​​grooves of the support seats and the fixing holes of the pallet are connected as one unit. The top of the pallet has a rod groove or bottom groove that facilitates the placement of the bottom of the frame and corresponds to the connecting rods.
