Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of stainless steel ultra-thick wall seamless tubes, and in particular relates to an anti-deformation support device for stainless steel ultra-thick wall seamless tubes. Background Technology
[0002] Ultra-thick-walled seamless stainless steel pipes refer to stainless steel products with a wall thickness significantly greater than that of conventional seamless steel pipes. Their outer diameter to wall thickness ratio is typically smaller, resulting in higher pressure resistance and structural strength. These pipes are made of stainless steel using a seamless manufacturing process, ensuring the integrity and reliability of the pipe material.
[0003] However, in existing technologies, pipe fittings are mostly stacked during management. Because the bottom pipe fitting bears the immense pressure from the multiple layers of pipe fittings above it, and because the pipe fitting itself is also heavy, the pressure on the bottom pipe fitting is further increased, making it highly susceptible to deformation. Furthermore, the direct contact between adjacent pipe fittings during stacking causes surface wear, affecting their appearance.
[0004] To address this, we propose a deformation-resistant support device for ultra-thick-walled seamless stainless steel tubes. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where pipe fittings are often stacked during management. Because the bottom pipe fitting bears the immense pressure of the multiple layers of pipe fittings above it, and the pipe fitting itself is also heavy, the pressure on the bottom pipe fitting is further increased, making it prone to deformation. Furthermore, the direct contact between adjacent pipe fittings during stacking leads to surface wear, affecting their appearance. Therefore, this invention proposes a deformation-resistant support device for ultra-thick-walled seamless stainless steel pipes.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A deformation-resistant support device for ultra-thick-walled seamless stainless steel tubes includes:
[0008] The mounting frame has several layered placement plates fixed between the inner walls of its two sides. The surface of the placement plates has multiple grooves. The top of the mounting frame has a top plate fixed. The bottom of the top plate and the bottom of the placement plates are each provided with two dividing components for dividing each stainless steel ultra-thick wall seamless tube.
[0009] The dividing component includes two fixed blocks fixed to the bottom of the placement plate, and a rotating shaft passes through the two fixed blocks. Multiple stop bars are fixed on the outer wall of the rotating shaft, and the bottom end of the stop bars is embedded in a groove when the shaft is in a vertical state.
[0010] One end of the rotating shaft is provided with a limiting mechanism for limiting the rotation of the shaft.
[0011] In one possible design, the limiting mechanism includes a limiting groove formed on the side wall of the fixed block and a bolt threaded through one side of the connecting block. The end of the bolt is selectively embedded in the limiting groove, and the other end of the bolt is fixed with an adjusting block.
[0012] In one possible design, the bottom of both the top plate and the placement plate is fixed with two fixing plates. The bottom of the fixing plates is provided with several slots. The inner walls on both sides of the slots are integrally formed with protrusions, and the protrusions and the stop rods are interference fit.
[0013] In one possible design, the outer wall of the stop bar is fitted with a protective sleeve, and both the protective sleeve and the fixing plate are made of rubber.
[0014] In one possible design, a first reinforcing plate is fixed on both sides of the mounting frame, and a second reinforcing plate is fixed between the mounting frame and the top plate.
[0015] In one possible design, side baffles are fixed on both sides of the surface of the placement plate.
[0016] In this application, when taking out the pipe fitting, the adjusting block is rotated to drive the bolt to rotate, so that the bolt is disengaged from the limiting groove. Then, the stop bar and the rotating shaft are rotated 90 degrees so that the stop bar is inserted into the slot and no longer obstructs the pipe fitting. Then the pipe fitting can be removed from the placement plate.
[0017] When placing the pipe fittings, place them on the placement plate, then rotate the stop bar to disengage them from the slot and lower them vertically. At this point, the bottom end of the stop bar is located in the groove. Then rotate the adjusting block to allow the bolt to enter the limiting groove.
[0018] Beneficial effects: In this utility model, the anti-deformation support device for stainless steel ultra-thick wall seamless pipe can arrange the pipes in layers by setting up multiple structures such as placement plate, rotating shaft and stop bar, so as to avoid stacking and squeezing. It can also separate adjacent pipes to avoid contact friction and prevent pipe deformation and wear.
[0019] In this utility model, the anti-deformation support device for stainless steel ultra-thick wall seamless pipe, through the setting of multiple structures such as fixing plate, slot and limiting slot, can facilitate people to quickly separate the pipe and can retract the stop bar to facilitate the removal of the pipe. The operation is simple and convenient.
[0020] In this invention, pipe fittings can be arranged in layers to avoid stacking and squeezing, and adjacent pipe fittings can be separated to avoid contact and friction, thus preventing deformation and wear. It also allows people to quickly separate the pipe fittings and retract the baffle to facilitate the removal of the pipe fittings. The operation is simple and convenient. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0028] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0029] Example 1: Refer to Figures 1-3A support device includes a mounting frame 1, which is a rectangular frame structure welded from H-beams. The distance between the inner walls on both sides is 1.2 times the length of the pipe fitting. Several placement plates 2 are horizontally welded to the inner walls of the mounting frame 1. The vertical distance between adjacent placement plates 2 is 1.5 times the outer diameter of the pipe fitting. Multiple grooves 4 are machined on the surface of the placement plates 2, and the depth of the grooves 4 is 2 / 3 of the diameter of the stop bar 9. A top plate 3 is fixed to the top of the mounting frame 1 by bolts, and its bottom is symmetrically equipped with dividing components on the bottom of the placement plates 2.
[0030] The segmentation assembly includes two fixed blocks 7, which are vertically fixed to both ends of the bottom surface of the placement plate 2 by welding. A rotating shaft 8 passes through the two fixed blocks 7 via rolling bearings. Multiple stop bars 9 are welded to the outer wall of the rotating shaft 8. The stop bars 9 are evenly distributed circumferentially, and their axial spacing is equal to 1.1 times the outer diameter of the pipe fitting. A rubber protective sleeve 10 with a thickness of 2mm and a Shore A hardness of 60A is interference-fitted onto the outer wall of each stop bar 9. One end of the rotating shaft 8 extends to the outside of the fixed block 7, and a limiting groove 17 is machined at this end. When the stop bar 9 is in a vertical position, its bottom end is located within the groove 4, which prevents the pipe fitting from pushing the stop bar 9 and causing it to bend and deform, ensuring the stability of the structure.
[0031] A limiting mechanism is provided on one side of the rotating shaft 8. The limiting mechanism includes a connecting block 11, which is fixed to the side wall of the fixing block 7 by screws. A bolt 12 is threaded through one side of the connecting block 11, and its end is located in the limiting groove 17. An adjusting block 13 is welded to the head of the bolt 12, and the surface of the adjusting block 13 is machined with anti-slip texture. When the bolt 12 is screwed into the limiting groove 17, the rotating shaft 8 is locked in the vertical position of the stop 9; when the bolt 12 is removed from the limiting groove 17, the rotating shaft 8 can rotate freely by 90°.
[0032] Two fixing plates 14 are welded to the bottom of the top plate 3 and the placement plate 2. The bottom surface of the fixing plate 14 is machined with multiple slots 15, the width of which is the same as the diameter of the stop rod 9. The inner walls on both sides of the slots 15 are integrally formed with protrusions 16 to restrict the rotation of the stop rod 9. When the rotating shaft 8 rotates 90°, the stop rod 9 is inserted into the slots 15, and the protrusions 16 and the stop rod 9 are in an interference fit.
[0033] This application can be used in the field of stainless steel ultra-thick wall seamless pipes, as well as in other fields applicable to this application.
[0034] Example 2: An improved anti-deformation support device for ultra-thick-walled seamless stainless steel tubes based on Example 1, which is applied to the field of ultra-thick-walled seamless stainless steel tubes.
[0035] In one aspect of this embodiment, side baffles 18 are welded to both sides of the surface of the placement plate 2. The height of the side baffles 18 is 1 / 2 of the outer diameter of the pipe, and rubber buffer pads are attached to the inner side. First reinforcing plates 5 are welded to both sides of the mounting frame 1, and a second reinforcing plate 6 is welded between the mounting frame 1 and the top plate 3.
