Description

Technical Field

[0001] This utility model relates to the field of cooling spray pipe manufacturing technology, specifically a positioning device for manufacturing cooling spray pipes. Background Technology

[0002] In the manufacturing process of cooling spray pipes in the slag beneficiation industry, the spray head is a key component (see reference). Figure 1 Its structure typically includes one DN50 main pipe 16 and four DN25 branch pipes 17. To meet the requirements of uniformity and coverage of the spray, these four branch pipes 17 need to be arranged at mutually symmetrical angles in a multi-dimensional space.

[0003] The current manufacturing process employs a traditional workflow of "compare dimensions one by one - precise positioning - drilling and machining - component welding assembly - welding and forming". However, due to the large demand for spray heads, continuing to manufacture them one by one using the above process would not only be time-consuming but could also prevent the mineral processing system from completing its trial run and production as planned. Furthermore, the relatively small diameter of the DN50 main pipe 16 and branch pipe 17, and the requirement for angle positioning of the four branch pipes 17 via a mitered tee structure, further complicates the manufacturing process. Traditional methods often require repeated adjustments and calibrations when dealing with such multi-dimensional angle positioning, which not only consumes a lot of manpower but also makes it difficult to guarantee the manufacturing accuracy and consistency of each spray head, thus hindering the improvement of overall manufacturing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for manufacturing cooling spray pipes, which solves the problems of the current manufacturing process of cooling spray pipes, which is time-consuming due to the large demand, which can delay the commissioning of mineral processing systems; and the difficulty in achieving multi-dimensional angle positioning of DN50 main pipes and small-diameter branch pipes through oblique tees, which requires repeated calibration, is not only labor-intensive, but also difficult to guarantee accuracy and consistency, which seriously restricts the manufacturing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for manufacturing cooling spray pipes, comprising a circular base plate, two main pipe support mechanisms, two sets of first branch pipe support mechanisms, and two sets of second branch pipe support mechanisms; the two main pipe support mechanisms are horizontally spaced on the upper side of the circular base plate; both sets of first branch pipe support mechanisms are located on the upper side of the circular base plate and on one side of one main pipe support mechanism, and the two sets of first branch pipe support mechanisms are obliquely mirror-symmetrically distributed along the horizontal line connecting the two main pipe support mechanisms; both sets of second branch pipe support mechanisms are located on the upper side of the circular base plate and on one side of the other main pipe support mechanism, and the two sets of second branch pipe support mechanisms are obliquely mirror-symmetrically distributed along the horizontal line connecting the two main pipe support mechanisms; each set of first branch pipe support mechanisms and each set of second branch pipe support mechanisms includes two first branch pipe support units and two second branch pipe support units arranged radially from the inside out at intervals.

[0006] Furthermore, the first branch pipe support unit, the second branch pipe support unit, and the main pipe support mechanism each include a support pipe, a nut on the upper side of the support pipe, a threaded rod threadedly connected to the nut and whose lower end can extend into the interior of the support pipe, a fixing block on the upper side of the threaded rod, a Y-shaped pipe support rotatably connected to the upper side of the fixing block via a bearing, a collar on the upper side of the fixing block and sleeved on the vertical section of the Y-shaped pipe support, and a set screw threadedly engaged with the outer wall of the collar and whose end is pressed against the vertical section of the Y-shaped pipe support. The support pipes of the first branch pipe support unit and the main pipe support mechanism are all connected to the upper side of the circular base plate.

[0007] Furthermore, the upper side of the circular base plate is provided with an annular groove, and the lower side of the annular groove is provided with a plurality of limiting holes arranged at an annular interval. A T-shaped slider is slidably connected inside the annular groove, and a bolt is threadedly connected to the upper side of the T-shaped slider. One end of the bolt passes through the T-shaped slider and abuts against the corresponding limiting hole. The support pipe of the second branch pipe support unit is connected to the upper side of the T-shaped slider.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention overcomes the drawbacks of traditional processes, such as long processing times and low efficiency, by utilizing a combination of a circular base plate, two main pipe support mechanisms 2, two sets of first branch pipe support mechanisms, and two sets of second branch pipe support mechanisms in the manufacturing of cooling spray pipes. Furthermore, it improves the manufacturing precision and consistency of complex-angle multi-dimensional tee cooling spray pipes. In terms of positioning, it can control the spatial positions of the main pipe 16 and each branch pipe 17. Even when encountering the complex challenge of angular positioning of the DN50 main pipe 16 and small-diameter branch pipes 17 through a mitered tee structure, it can be adjusted in one go, eliminating repeated adjustments and calibrations, and significantly saving manpower and time costs. Simultaneously, this device has the ability to flexibly adapt to the manufacturing needs of cooling spray pipes of different specifications and angles, improving overall manufacturing efficiency and ensuring that the mineral processing system can complete commissioning and production as planned, providing strong support for the smooth progress of the project.

Detailed Implementation

[0015] Please see Figure 2-4A positioning device for manufacturing cooling spray pipes includes a circular base plate 1, two main pipe support mechanisms 2, two sets of first branch pipe support mechanisms, and two sets of second branch pipe support mechanisms. The two main pipe support mechanisms 2 are horizontally spaced on the upper side of the circular base plate 1. The two sets of first branch pipe support mechanisms are both located on the upper side of the circular base plate 1 and on one side of one main pipe support mechanism 2, and the two sets of first branch pipe support mechanisms are obliquely mirror-symmetrically distributed along the horizontal line connecting the two main pipe support mechanisms 2. The two sets of second branch pipe support mechanisms are both located on the upper side of the circular base plate 1 and on one side of the other main pipe support mechanism 2, and the two sets of second branch pipe support mechanisms are obliquely mirror-symmetrically distributed along the horizontal line connecting the two main pipe support mechanisms 2. Each set of first branch pipe support mechanisms and each set of second branch pipe support mechanisms includes two first branch pipe support units 3 and second branch pipe support units 4 arranged radially from the inside to the outside at intervals.

[0016] The first branch pipe support unit 3, the second branch pipe support unit 4, and the main pipe support mechanism 2 all include a support pipe 5, a nut 6 welded to the upper side of the support pipe 5, a threaded rod 7 threaded to the nut 6 and whose lower end can extend into the interior of the support pipe 5, a fixing block 9 welded to the upper side of the threaded rod 7, a Y-shaped pipe support 8 rotatably connected to the upper side of the fixing block 9 via a bearing, a collar 14 connected to the upper side of the fixing block 9 and fitted onto the vertical section of the Y-shaped pipe support 8, and a set screw 15 threaded to the outer wall of the collar 14 and whose end is pressed against the vertical section of the Y-shaped pipe support 8. The support pipes 5 of the first branch pipe support unit 3 and the main pipe support mechanism 2 are all connected to the upper side of the circular base plate 1. First, through the threaded connection between the threaded rod 7 and the nut 6, the horizontal calibration and height adjustment of the main pipe 16 and the branch pipe 17 in the vertical direction are realized, ensuring the horizontal state and accurate positioning of the pipeline, laying a solid foundation for subsequent drilling and welding assembly work. Secondly, the Y-shaped pipe support 8 is rotatably connected to the fixing block 9 via a bearing, which facilitates the flexible rotation of the main pipe 16 and the branch pipe 17 during placement and adjustment, improving the convenience and efficiency of operation. After the Y-shaped pipe support 8 is rotated to the appropriate angle, the operator rotates the set screw 15 toward the inside of the collar 14. As the set screw 15 goes deeper, its end gradually presses against the outer wall of the vertical section of the Y-shaped pipe support 8, achieving a stable lock on the position of the Y-shaped pipe support 8.

[0017] An annular groove 10 is provided on the upper side of the circular base plate 1. Multiple limiting holes 13, spaced annularly, are provided on the lower side of the annular groove 10. A T-shaped slider 11 is slidably connected inside the annular groove 10. A fixing bolt 12 is threaded onto the upper side of the T-shaped slider 11. One end of the fixing bolt 12 passes through the T-shaped slider 11 and abuts against the corresponding limiting hole 13. The support pipe 5 of the second branch pipe support unit 4 is connected to the upper side of the T-shaped slider 11. When manufacturing branch pipes 17 with different tilt angles, the second branch pipe support unit 4 can be adjusted to a suitable position. The stability of the support pipe 5 is ensured by the cooperation of the fixing bolt 12 and the limiting holes 13. This meets the requirements for branch pipe positioning accuracy during the manufacturing of complex angle multi-dimensional three-way cooling spray pipes, improving manufacturing flexibility and efficiency, and also enhancing the applicability and adjustability of the positioning device.

[0018] Working Process and Principle: In the fabrication of a cooling spray pipe with complex angled multi-dimensional tees, a circular base plate 1 is used as the foundation platform. The DN50 main pipe 16 is placed on the Y-shaped pipe supports 8 of the two horizontally spaced main pipe support mechanisms 2 on the upper side of the circular base plate 1. By rotating the threaded rod 7, which is threaded to the nut 6 on the upper side of the support pipe 5, its length extending out of the support pipe 5 is adjusted, thereby precisely calibrating the DN50 main pipe 16 in the vertical direction. This ensures that the main pipe 16 is in a horizontal state, laying the foundation for the subsequent precise positioning and welding assembly of the branch pipes 17. In addition, the Y-shaped pipe supports 8 and the fixing block 9 are rotatably connected by bearings, facilitating the flexible rotation of the DN50 main pipe 16 during placement and adjustment.

[0019] When positioning branch pipe 17, place it on the corresponding Y-shaped pipe support 8, and adjust its height using the adjusting threaded rod 7. By rotating the threaded rod 7, change its length extending from the support pipe 5, thereby adjusting the angle of branch pipe 17 in space until it aligns with the support pipe. Figure 1 The angles shown are consistent, achieving precise positioning of branch pipe 17. If the position of the second branch pipe support unit 4 needs to be adjusted according to the tilt angle requirement of branch pipe 17, the T-shaped slider 11 can be slid to a suitable position, and then the fixing bolt 12 on the upper side of the T-shaped slider 11 can be tightened so that one end of it passes through the T-shaped slider 11 and tightly abuts against the corresponding limiting hole 13 on the lower side of the annular groove 10, thereby achieving the positioning of the second branch pipe support unit 4.

[0020] After the branch pipe 17 is positioned, the drilling operation can begin. Since the main pipe 16 and branch pipe 17 are already positioned, the hole positions are accurate, improving drilling precision and efficiency. After drilling, the main pipe 16 and branch pipe 17 can still be directly butt-welded onto the device without repositioning, further saving time and manpower. The device only needs to be adjusted once, and subsequent batches can be positioned and butt-welded according to the adjusted angles, improving manufacturing efficiency. Simultaneously, the device is adjustable; by increasing the position of the support pipe 5 and adjusting the length of the threaded rod 7, butt-welding assembly of any irregular multi-dimensional space cooling spray pipe or tee can be achieved.

[0021] In summary, this device enables rapid and precise butt welding assembly of complex-angle multi-dimensional tees in cooling spray pipes, improving manufacturing efficiency and quality while reducing labor and time costs.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
