Description

Technical Field

[0001] This utility model relates to the field of Ni3 low-temperature steel production technology, specifically to a conveying device for preparing flux for Ni3 low-temperature steel. Background Technology

[0002] Ni3 low-temperature steel is a low-alloy structural steel containing approximately 3% nickel, belonging to the ferritic-pearlitic type. It enhances the steel's low-temperature toughness through nickel, allowing the material to maintain good impact toughness and mechanical properties in environments ranging from -60℃ to -100℃, preventing low-temperature brittle fracture. Controlled rolling and cooling processes are commonly used to refine the grain size. It is primarily used to manufacture structural components for cryogenic storage tanks, liquefied natural gas equipment, refrigeration units, and other cryogenic applications, balancing low-temperature adaptability with processability.

[0003] Existing conveying devices mostly use fixed brackets for direct installation of the transmission pipes. Once the height and angle of the brackets are determined, they cannot be adjusted, making it impossible to adapt to different height and angle requirements. This results in difficulty in accurately connecting the transmission pipes to the equipment interface. In summary, in order to solve the above problems, improve the efficiency and quality of Ni3 low-temperature steel production, and reduce losses, this utility model has emerged. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a conveying device for preparing flux for Ni3 low-temperature steel, comprising: a transmission pipe, with an adjustment structure fixedly connected to both ends of the transmission pipe, the adjustment structure including a support frame, lifting grooves symmetrically opened on the outer wall of the support frame, a bidirectional lead screw rotatably connected to the inner wall of the support frame, a slider symmetrically threaded to the outer wall of the bidirectional lead screw, a support rod rotatably connected to the top of the slider, and a fixing structure rotatably connected to the top of the support rod.

[0005] Preferably, the fixing structure includes a fixing block, and the outer wall of the fixing block has a fixing hole.

[0006] Preferably, a rubber ring is fixedly connected to the inner wall of the fixing hole, and the inner diameter of the rubber ring matches the outer diameter of the transmission pipe.

[0007] Preferably, lifting blocks are symmetrically fixedly connected to both sides of the fixed block, and the outer wall of the lifting block is slidably connected to the inner wall of the lifting groove.

[0008] Preferably, the bottom of the fixing block is symmetrically fixedly connected with connecting blocks.

[0009] Preferably, the outer wall of the connecting block is rotatably connected to the inner wall of the support rod.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through its adjustable structure, allows the operator to simply rotate a bidirectional lead screw. The screw's threaded engagement with the sliders causes the two sliders to slide in opposite directions along the screw's axial direction. The support rod at the top of the sliders then changes its tilt angle, pushing the fixed structure up and down along the lifting groove, ultimately achieving precise adjustment of the transmission pipe height. The entire adjustment process requires no disassembly of the bracket or reinstallation of the transmission pipe; it can be completed simply by rotating the lead screw, making operation convenient and efficient.

[0012] 2. By setting up a fixing structure, the rubber ring can avoid direct contact and friction between the outer wall of the transmission pipe and the inner wall of the fixing hole, preventing wear and deformation of the outer wall of the transmission pipe due to long-term friction, extending the service life of the transmission pipe, and preventing impurities from being mixed into the flux due to pipe wall wear, ensuring the purity of the flux used in Ni3 low-temperature steel preparation. The lifting blocks on both sides of the fixing block slide with the lifting groove of the support frame, which can guide the fixing structure during the adjustment process, prevent the fixing structure from shifting, and ensure that the transmission pipe always remains in a stable and fixed state.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, 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 were chosen 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 a particular purpose.

[0018] Example:

[0019] Please see Figures 1-2This utility model provides a technical solution: a conveying device for preparing flux for Ni3 low-temperature steel, comprising: a transmission pipe 1, with adjusting structures 2 fixedly connected to both ends of the transmission pipe 1, the adjusting structure 2 including a support frame 21, lifting grooves 22 symmetrically opened on the outer wall of the support frame 21, a bidirectional lead screw 23 rotatably connected to the inner wall of the support frame 21, a slider 24 symmetrically threaded to the outer wall of the bidirectional lead screw 23, a support rod 25 rotatably connected to the top of the slider 24, and a fixing structure 26 rotatably connected to the top of the support rod 25. When it is necessary to adjust the height and tilt angle of the transmission pipe 1 to adapt to the equipment of the preceding and following processes according to the layout of the Ni3 low-temperature steel flux preparation workshop, the operator first confirms that the support frame 21 of the adjusting structure 2 is in a stable position. Then, the bidirectional lead screw 23 rotatably connected to the inner wall of the support frame 21 is rotated. Since the outer wall of the bidirectional lead screw 23 is symmetrically threaded to the slider 24, the rotation of the bidirectional lead screw 23 will drive the two sliders 24 to slide in opposite directions along the axial direction of the bidirectional lead screw 23. The support rod 25, rotatably connected to the top of the slider 24, moves synchronously. The top of the support rod 25 is rotatably connected to the fixed structure 26, thereby pushing the fixed structure 26 up and down along the lifting grooves 22 symmetrically opened on the outer wall of the support frame 21. During the adjustment process, the operator can observe the position change of the transmission pipe 1 and adjust the rotation direction and number of turns of the bidirectional lead screw 23 in real time: if it is necessary to raise the transmission pipe 1, the two sliders 24 slide in opposite directions, the tilt angle of the support rod 25 increases, and the fixed structure 26 rises; if it is necessary to lower the transmission pipe 1, the two sliders 24 slide towards each other, the tilt angle of the support rod 25 decreases, and the fixed structure 26 falls accordingly.

[0020] Please see Figure 3The fixing structure 26 includes a fixing block 261. The outer wall of the fixing block 261 has a fixing hole 264. A rubber ring 265 is fixedly connected to the inner wall of the fixing hole 264. The inner diameter of the rubber ring 265 matches the outer diameter of the transmission pipe 1. Lifting blocks 263 are symmetrically fixedly connected to both sides of the fixing block 261. The outer wall of the lifting block 263 is slidably connected to the inner wall of the lifting groove 22. A connecting block 262 is symmetrically fixedly connected to the bottom of the fixing block 261. The outer wall of the connecting block 262 is rotatably connected to the inner wall of the support rod 25. Before adjusting the position of the transmission pipe 1 through the adjusting structure 2, the transmission pipe 1 and the fixing structure 26 must be fixedly connected first. The operator aligns the end of the transmission pipe 1 with the fixing hole 264 on the outer wall of the fixing block 261. Since the inner diameter of the rubber ring 265 fixedly connected to the inner wall of the fixing hole 264 matches the outer diameter of the transmission pipe 1, the outer wall of the transmission pipe 1 can fit tightly against the inner wall of the rubber ring 265 and be inserted into the fixing hole 264. The rubber ring 265 not only enhances the sealing between the transmission pipe 1 and the fixing hole 264, preventing flux leakage at the connection point, but also avoids direct friction between the outer wall of the transmission pipe 1 and the inner wall of the fixing hole 264, preventing wear. After the connection between the transmission pipe 1 and the fixing block 261 is completed, the lifting blocks 263 symmetrically fixedly connected on both sides of the fixing block 261 will slide against the inner wall of the lifting groove 22 of the support frame 21, ensuring that the fixing structure 26 moves stably along the lifting groove 22 during adjustment without deviation. Meanwhile, the connecting block 262, which is symmetrically fixed at the bottom of the fixed block 261, is rotatably connected to the inner wall of the support rod 25. This ensures that when the support rod 25 moves, the fixed block 261 can adjust its height according to the angle change of the support rod 25, and always maintain a stable connection with the transmission pipe 1. This avoids the impact of structural jamming on the position adjustment accuracy of the transmission pipe 1 during the adjustment process, and ultimately achieves reliable fixing and flexible adjustment of the transmission pipe 1.

[0021] Working principle:

[0022] When adjusting the height and tilt angle of the transmission pipe 1 to match the upstream and downstream equipment according to the layout of the Ni3 low-temperature steel flux preparation workshop, the operator first confirms that the support frame 21 of the adjustment structure 2 is in a stable position. Then, the double-ended lead screw 23, rotatably connected to the inner wall of the support frame 21, is rotated. Since the outer wall of the double-ended lead screw 23 is symmetrically threaded to the slider 24, the rotation of the double-ended lead screw 23 will cause the two sliders 24 to slide in opposite directions along the axial direction of the double-ended lead screw 23. The support rod 25, rotatably connected to the top of the slider 24, moves synchronously. The top of the support rod 25 is rotatably connected to the fixed structure 26, thereby pushing the fixed structure 26 up and down along the symmetrically opened lifting grooves 22 on the outer wall of the support frame 21. During the adjustment process, the operator can observe the position change of the transmission tube 1 and adjust the rotation direction and number of turns of the bidirectional lead screw 23 in real time: if the transmission tube 1 needs to be raised, the two sliders 24 slide in opposite directions, the tilt angle of the support rod 25 increases, and the fixed structure 26 rises; if the transmission tube 1 needs to be lowered, the two sliders 24 slide towards each other, the tilt angle of the support rod 25 decreases, and the fixed structure 26 falls accordingly. Before adjusting the position of the transmission tube 1 through the adjustment structure 2, the transmission tube 1 and the fixed structure 26 must be fixedly connected first. The operator aligns the end of the transmission pipe 1 with the fixing hole 264 on the outer wall of the fixing block 261. Since the inner diameter of the rubber ring 265 fixedly connected to the inner wall of the fixing hole 264 matches the outer diameter of the transmission pipe 1, the outer wall of the transmission pipe 1 can fit tightly against the inner wall of the rubber ring 265 and be inserted into the fixing hole 264. The rubber ring 265 not only enhances the sealing between the transmission pipe 1 and the fixing hole 264, preventing flux leakage at the connection point, but also avoids direct friction between the outer wall of the transmission pipe 1 and the inner wall of the fixing hole 264, preventing wear. After the connection between the transmission pipe 1 and the fixing block 261 is completed, the lifting blocks 263 symmetrically fixedly connected on both sides of the fixing block 261 will slide against the inner wall of the lifting groove 22 of the support frame 21, ensuring that the fixing structure 26 moves stably along the lifting groove 22 during adjustment without deviation. Meanwhile, the connecting block 262, which is symmetrically fixed at the bottom of the fixed block 261, is rotatably connected to the inner wall of the support rod 25. This ensures that when the support rod 25 moves, the fixed block 261 can adjust its height according to the angle change of the support rod 25, and always maintain a stable connection with the transmission pipe 1. This avoids the impact of structural jamming on the position adjustment accuracy of the transmission pipe 1 during the adjustment process, and ultimately achieves reliable fixing and flexible adjustment of the transmission pipe 1.
