A rack for steel pipe machining

Abstract

The application discloses a steel pipe processing placing rack, and belongs to the technical field of placing racks for storing and circulating steel pipe materials. The steel pipe processing placing rack comprises a rack body for supporting steel pipes, and a steel pipe restraining mechanism which is detachably arranged on the rack body and is used for wrapping and limiting a plurality of steel pipes. The rack body comprises a bottom plate, a first layer of support columns and a second layer of support columns arranged on the bottom plate. A plurality of support rods are arranged on the first layer of support columns and the second layer of support columns, and the height of the support rods on the second layer of support columns is lower than that of the support rods on the first layer of support columns. The steel pipe processing placing rack has the beneficial effect of providing a three-angle lock which can be opened and closed. Two breakthroughs are realized. When the rack body is moved, the closed lock can effectively prevent the steel pipes from rolling and scattering, and manual binding is not needed, so that the safety is very high. When the steel pipes are lifted, the overhead crane can directly and unobstructedly lift the lowest layer of steel pipes, so that the work efficiency and safety are greatly improved.

Description

Technical Field

[0001] This application relates to a storage rack for storing and handling steel pipe materials, and more specifically, to a storage rack for steel pipe processing. Background Technology

[0002] Steel pipe processing racks are core equipment in workshops and warehouses used for carrying, storing, and transferring steel pipes. Their basic structure typically includes a main frame and multiple layers of support structures, designed to achieve orderly storage of steel pipes, avoiding direct stacking on the ground, thus saving space and facilitating management. An ideal rack should possess stability, high space utilization, and convenient access to ensure operational safety and improve logistics efficiency.

[0003] First, traditional fixed racks (such as V-groove racks and cantilever racks) have significant limitations in practical applications. Because their frames are fixed to the ground, their storage location is difficult to adjust once determined. This exposes their poor flexibility and adaptability in workshops requiring frequent adjustments to production layouts or flexible manufacturing. When production line processes change, relocating fixed racks requires the use of large equipment for hoisting, a cumbersome and costly process that fails to meet the demands of modern intelligent manufacturing for rapid reconfiguration of production units.

[0004] To overcome the rigidity of fixed shelving, the industry has proposed movable shelving, which involves adding casters to the bottom of the frame to give it mobility. However, this improvement introduces new and more complex derivative problems:

[0005] Safety risks during relocation: To prevent the steel pipes from rolling, slipping, or even causing the frame to overturn due to inertia during pushing, operators must manually bind and secure the steel pipes inside the frame before relocation. This process is not only time-consuming and labor-intensive, greatly diminishing the efficiency advantage brought by its mobility, but also the reliability of the binding depends entirely on manual operation, posing a significant safety hazard.

[0006] The Dilemma of Lifting in Multi-Layer Structures: Pushable placement racks are often designed as multi-layer structures to improve space utilization. However, this structure exposes a fatal flaw during lifting operations. When using overhead cranes with lifting booms and other lifting equipment, the enclosed and mutually obstructing spaces on each layer mean that the lifting equipment can only prioritize, or even only lift, the steel pipes on the top layer. Steel pipes on the middle and lower layers cannot be lifted directly and efficiently. Operators must first remove all or part of the upper-layer steel pipes before they can access the target pipe. This process is not only cumbersome and extremely inefficient, but also greatly increases the risk of surface bumps and scratches caused by frequent movement of the steel pipes, and also easily leads to safety accidents such as steel pipes rolling down.

[0007] Therefore, a steel pipe processing rack is needed to solve the above problems. Utility Model Content

[0008] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0009] In order to solve the technical problems mentioned in the background section above, some embodiments of this application provide a steel pipe processing placement rack that aims to solve the problems of high movement safety risks and difficulty in lifting low-level steel pipes in existing mobile placement racks, including:

[0010] The main frame supports the steel pipes;

[0011] The steel pipe restraint mechanism is detachably installed on the main frame to wrap and limit the movement of several steel pipes.

[0012] The main frame includes a base plate and a first layer of support columns set on the base plate. The base plate is provided with a sliding groove, on which a second layer of support columns are slidably mounted. Support rods for horizontally supporting steel pipes are fixedly provided on the first and second layer support columns along their height direction, and the height of the support rods on the second layer support columns is lower than that on the first layer support columns. The second layer support columns and the first layer support columns are fixedly connected to each other by a locking structure.

[0013] Furthermore, the support rod is provided with several connecting blocks along its length, and each connecting block is detachably connected to a V-shaped fixing rod with the opening of the V-shaped fixing rod facing upward to support the steel pipe.

[0014] Furthermore, the steel pipe restraint mechanism includes a V-shaped fixing rod, one end of which is rotatably connected to a fixing plate via a rotating shaft; the other end of the V-shaped fixing rod has a groove for the fixing plate to be embedded in.

[0015] Furthermore, a limiting block is slidably connected to the fixed plate, and a threaded block is threaded to one end of the limiting block; when the fixed plate is embedded in the groove, the limiting block can slide to the junction of the fixed plate and the V-shaped fixing rod, and by tightening the threaded block, it can be made to fit against the side of the fixed plate, thereby locking the position of the limiting block and restricting the fixed plate from flipping.

[0016] Preferably, a moving mechanism is provided at the bottom of the base plate.

[0017] Preferably, the locking structure is a pin-type lock, a rotary lock, or a bolt fastener.

[0018] Preferably, the V-shaped fixing rod is detachably connected to the connecting block by bolts or snap-fit.

[0019] The beneficial effects of this application are as follows:

[0020] A steel pipe restraint mechanism consisting of a V-shaped fixing rod, a fixing plate, a limiting block, and a threaded block was designed. Before moving the placement frame, the fixing plate can be quickly flipped down and locked with the limiting block, forming an effective protective structure with the V-shaped fixing rod to prevent the steel pipe from rolling off due to inertia during movement. This eliminates the need for cumbersome manual binding, making the operation simple, safe, and reliable.

[0021] Because the second-layer support can slide relative to the first-layer support, when it is necessary to lift the steel pipes on the second-layer support, the locking structure can be released, and the entire second-layer support and the steel pipes on it can be slid out from under the first-layer support, so that they are fully exposed to the working range of the overhead crane, thereby realizing the direct and unobstructed lifting of steel pipes from all layers, completely solving the problem of lifting multi-layer scaffolds, improving work efficiency, and reducing safety risks and the risk of steel pipe damage.

[0038] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Reference Figure 1-7 The present invention provides a steel pipe processing rack, which mainly includes a rack body, a moving mechanism, and a steel pipe restraint mechanism. The rack body consists of a rectangular base plate 1 forming a base. The moving mechanism includes swivel casters 2 with brakes installed at the four corners of the bottom of the base plate 1, allowing the entire rack to be easily moved and fixed.

[0040] The main frame also includes a first-layer support column 3 and a second-layer support column 4. The first-layer support column 3 is fixedly installed on the base plate 1. One or more sliding grooves 5 are formed on the upper surface of the base plate 1. The bottom of the second-layer support column 4 is installed in the sliding groove 5 by means of a slider 41 or rollers, allowing it to slide horizontally along the sliding groove 5. Multiple horizontally extending support rods 6 are fixedly installed on both the first-layer support column 3 and the second-layer support column 4. The height of the support rods 6 on the second-layer support column 4 is lower than that on the first-layer support column 3, thus naturally forming upper and lower storage spaces. By sliding the second-layer support column 4, the overlap between the two storage spaces can be adjusted. When the second-layer support column 4 slides to a position close to the first-layer support column 3, the two are fixed by a pin-type locking structure 7 to ensure structural stability during use.

[0041] On each support rod 6, multiple connecting blocks 8 are welded at intervals along its length. Each connecting block 8 is detachably mounted with a V-shaped fixing rod 9 by bolts or a clamping structure. The opening of the V-shaped fixing rod 9 faces upward and is used to support the steel pipe 15.

[0042] The core component of the steel pipe restraint mechanism is located on the V-shaped fixing rod 9. One end of the V-shaped fixing rod 9 is rotatably connected to a long strip-shaped fixing plate 11 via a rotating shaft 10. The other end of the V-shaped fixing rod 9 has a groove 12 that matches the shape of the fixing plate 11. The limiting block 13 has a sliding hole, and the limiting block 13 is sleeved on the fixing plate 11 through the sliding hole to achieve the sliding setting of the limiting block 13 and the fixing plate 11. One end of the limiting block 13 has an external thread and a nut, which serves as a threaded block 14, is screwed on.

[0043] Working principle and usage process:

[0044] Storage state: Flip the fixing plate 11 upwards to open it. At this time, the opening of the V-shaped fixing rod 9 is fully exposed, and the steel pipe 15 can be smoothly placed into the V-shaped groove.

[0045] Preparation for relocation: When the placement rack needs to be moved, rotate the fixing plate 11 on each V-shaped fixing rod 9 downwards so that it is embedded in the corresponding groove 12. Then, slide the limiting block 13 towards the V-shaped fixing rod 9 until part of the limiting block 13 moves above the hinge area between the fixing plate 11 and the V-shaped fixing rod 9. Finally, tighten the threaded block 14 by hand so that it presses firmly against the side of the fixing plate 11, thereby locking the limiting block 13 securely. At this point, the fixing plate 11 and the limiting block 13 together form a guardrail, effectively preventing the steel pipe 15 from rolling out during relocation.

[0046] Lifting operation: When it is necessary to lift the steel pipe 15 located on the second-level support 4, first open the locking structure 7, and then pull the second-level support 4 outward so that it carries all the steel pipes 15 on it and slides completely out from under the first-level support 3. At this time, the lower steel pipe 15 is fully exposed, and the overhead crane can lift the steel pipe 15 and the steel pipe restraint mechanism directly and vertically, just like lifting the upper steel pipe, without removing the upper steel pipe.

[0047] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the application involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept.
