Description

Technical Field

[0001] The utility model relates to the field of pipeline steel production auxiliary components, in particular to a pipeline steel storage device. Background Art

[0002] Pipeline steel refers to a type of steel with special requirements used for transporting oil, natural gas and other pipelines. Depending on the thickness and subsequent forming, it can be produced by hot rolling mills, Steckel mills or medium and heavy plate mills, and formed into large-diameter steel pipes through spiral welding or UOE straight seam welding; Figure 1 As shown, after the production and processing of pipeline steel 1 is completed, it is necessary to centrally store and stack the materials. When multiple layers are stacked up and down, the lower layer pipeline steel 1 needs to be limited relative to each other to prevent the pipeline steel 1 material pile from collapsing and rolling. The commonly used limiting components are ordinary processed steel plates 2. The steel plates 2 are slit and clamped on the ports of two adjacent pipeline steels 1. The principle is similar to that of a pair of pliers that cannot be opened. However, it is found in actual use that the force-bearing surface is very small, so it often causes slight deformation and scratches at the ports of pipeline steel 1, especially when many layers are stacked, the lower layer pipeline steel 1 is more prone to such phenomena. Therefore, a storage auxiliary device that can effectively avoid damage to pipeline steel 1 is needed. Utility Model Content

[0019] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 2-6 As shown, the pipeline steel storage device described in this embodiment includes an intermediate box 3 and top claws 4 symmetrically arranged on the left and right sides of the intermediate box 3; a screw sleeve 5 and a worm 6 are rotatably arranged in the intermediate box 3, and a worm wheel 7 coaxially fixed to the outside of the screw sleeve 5 that cooperates with the worm 6. One end of the worm wheel 7 extends to the outside of the intermediate box 3 and is fixed to this end with a screw head 8. The screw head 8 is a hexagonal nut that can be screwed by a wrench or open-end wrench of corresponding specifications; two horizontal screws 9 are also symmetrically screwed in the screw sleeve 5. When the screw sleeve 5 rotates, the two horizontal screws 9 move closer to or away from each other;

[0022] The top claw 4 includes a base block 10, an intermediate rod 11 fixed on the base block 10 and oblique supports symmetrically arranged on the upper and lower sides of the intermediate rod 11. The oblique support includes an intermediate screw sleeve 12 and an oblique screw 13 symmetrically screwed in the intermediate screw sleeve 12. When the intermediate screw sleeve 12 rotates, the two oblique screws 13 move closer to or away from each other. A support piece 14 is fixed to the end of the intermediate rod 11. The support piece 14 is a steel sheet. One end of the oblique screw 13 is hingedly connected to the support piece 14, and the end of the other oblique screw 13 is hingedly connected to the base block 10. The base block 10 is also fixedly connected to one end of the horizontal screw 9.

[0023] An auxiliary limiting mechanism is also provided on the intermediate box 3, which applies auxiliary limiting to the worm 6 in addition to the self-locking nature of the worm wheel 7 and worm 6, so as to prevent the two top claws 4 from moving away from each other due to the self-rotation of the screw sleeve 5. The auxiliary limiting mechanism includes a limit rod 15 which can be raised and lowered and arranged on the intermediate box 3, and a gear 16 which is coaxially fixed on the worm 6. Specifically, a sliding sleeve 17 is fixed on the intermediate box 3, and the limit rod 15 is slidably arranged in the sliding sleeve 17. The lower end of the limit rod 15 is fixed with an arc-shaped rack 18 which cooperates with the gear 16, and the upper end of the limit rod 15 is fixed with a counterweight 19 to facilitate the lowering and maintaining of the limit rod 15 in position; after the arc-shaped rack 18 and the gear 16 cooperate, the worm 6 is less likely to rotate on its own, thereby realizing the auxiliary limiting of the worm 6.

[0024] In order to facilitate the workers to lift and maintain the limit rod 15 when screwing the worm 6, the material of the arc rack 18 is set to cast iron and a permanent magnet 20 is set on the bottom of the sleeve 17. The limit rod 15 is pulled up and the arc rack 18 is adsorbed onto the permanent magnet 20. At this time, the workers can free their hands to screw the worm 6.

[0025] The working principle of this embodiment is:

[0026] The two top claws 4 are initially placed into the two adjacent pipeline steels 1, and the worm 6 is screwed. The worm 6 drives the screw sleeve 5 to rotate through the worm gear 7, and the two horizontal screws 9 are close to each other. The two top claws 4 gradually clamp the two adjacent pipeline steels 2 until the middle rod 11 is tight, and then the middle screw sleeve 12 is manually screwed to make the two ends of the support piece 14 also fit well with the inner avoidance surface of the pipeline steel 1; this embodiment can be used in conjunction with a wrench to effectively fix the adjacent pipeline steels 1. Compared with the prior art, the contact area with the pipeline steel 1 is larger and there is no sharp contact, which can effectively avoid local stress deformation and scratches of the pipeline steel 1; in addition, the top claw 4 in this embodiment itself can adjust the shape and the spacing between the two top claws 4 can also be adjusted, which is applicable to pipeline steels 1 of different specifications and has strong practicality.

[0027] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
