Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, and in particular to a coil crucible support bracket. Background Technology

[0002] Traditional support brackets typically consist of a fixed plate for connection to the equipment base and a horizontal support plate welded perpendicularly or nearly perpendicularly to the fixed plate. The melting coil is directly mounted and fixed on this horizontal support plate. Due to the significant weight of the melting coil itself, the thickness of the support plate must be greatly increased, resulting in a tall support structure. When the melting coil is tilted after melting, the height between its tip and the vessel below is relatively large, making it prone to splashing and scattering.

[0003] An existing patent (publication number CN220033216U) discloses a novel flipping device, including a support, a flipping device, and a motor; the motor is connected to the side of the support, and the flipping device is connected to the support; the support has a driven shaft and a driving shaft, the output end of the motor is connected to one end of the flipping device through the driving shaft, and the other end of the flipping device is connected to the support through the driven shaft; the flipping device includes a flipping frame, a clamping assembly, and a base assembly; the flipping frame is positioned between the driven shaft and the driving shaft; the base assembly and the clamping assembly are both connected to the flipping frame; However, it can only rotate the crucible at a fixed height. When pouring molten metal, the height difference between the equipment and the receiving container is large, which will cause the molten metal to splash. It cannot reduce the splashing of molten metal by lowering the height of the crucible. Summary of the Invention

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings: If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0020] like Figures 1-6 As shown, the coil crucible support bracket of the present invention includes: The base 10 serves as a fixing base for other components; An electrically heated crucible 32, which is fixedly equipped with a crucible ring frame 33, has two symmetrical connecting ends. Support arms 18, two symmetrically arranged on the base 10, each support arm 18 includes a rotatable lead screw shaft 13, and a drive slider 17 is configured to cooperate with the lead screw shaft 13 and can move along the axis of the lead screw shaft 13; The support bracket 22 has two connecting ends and is rotatably arranged relative to the drive slider 17 with the axis of rotation perpendicular to the axis of the lead screw shaft 13. The two connecting ends of the crucible ring frame 33 are fixedly connected to the support bracket 22 by bolts. The coupling assembly includes a synchronizing gear 24 and a rack 23, wherein the rack 23 is vertically arranged, the synchronizing gear 24 is fixed on the support bracket 22 and coaxial with its rotating shaft, and the rack 23 and the synchronizing gear 24 mesh. The drive source is used to output torque and drive the lead screw shaft 13 to rotate through the transmission component. Specifically, the drive source can be various types of motors in the prior art, and the transmission component can be V-belt drive, chain drive, etc. in the prior art. After the motor outputs torque, the screw shaft 13 moves, causing the drive slider 17 to move downward in cooperation with the screw shaft 13. At the same time, the synchronous gear 24 meshes with the rack 23, thereby enabling the support bracket 22 to rotate while descending, which can reduce the casting height during metallurgical casting.

[0021] In a preferred embodiment, the support arm 18 further includes a steel structure arm 11, a guide rail 12, and a synchronous pulley 14. The guide rail 12 is vertically fixed on the steel structure arm 11. The drive slider 17 includes a slider component 15 and a lead screw nut 16, wherein the lead screw nut 16 is fixed inside the slider component 15. The side wall of the slider component 15 is provided with a slider block that slides vertically and vertically with the guide rail 12 to ensure that the slider component 15 does not rotate relative to the steel structure arm 11, thereby improving the stability of the slider component 15 sliding vertically. The lead screw nut 16 is engaged with the lead screw shaft 13. When the lead screw shaft 13 rotates, it drives the drive slider 17 to move vertically and vertically through the movement of the helical pair, thereby adjusting the position of the support bracket 22 supporting the electrically heated crucible 32, lowering the height of the pouring opening, and reducing the splashing of molten metal during the pouring process.

[0022] In a preferred embodiment, the support arm 18 further includes a timing pulley 14 (e.g., Figure 1 The synchronous pulleys 14 are connected synchronously by a synchronous belt (the specific models of the synchronous belt and synchronous pulleys 14 can be selected from existing technologies). The structural design of the synchronous belt enables the two lead screw shafts 13 to maintain high rotational synchronization, so that the two ends of the support bracket 22 will perform synchronous actions, improving stability.

[0023] In a preferred embodiment, a third synchronous pulley 29 is coaxially fixed on any one of the lead screw shafts 13, and a second synchronous pulley 28 is coaxially fixed at the output shaft of the drive source. A matching synchronous belt is provided between the second synchronous pulley 28 and the third synchronous pulley 29. The drive source drives one of the lead screw shafts 13 to rotate and transmits torque to the other lead screw shaft 13 synchronously through the synchronous belt, so that the two lead screw shafts 13 rotate synchronously, ensuring the synchronous drive of the lead screw shafts 13.

[0024] In a preferred embodiment, the drive source includes a servo motor 26 and a planetary reducer 27 adapted to the servo motor 26. The planetary reducer 27 reduces the output shaft speed of the servo motor 26 and increases the torque, and outputs it to drive the lead screw shaft 13 to rotate. The servo motor 26 and the planetary reducer 27 are fixed to the steel structure arm 11 by bolts.

[0025] In a preferred embodiment, the support bracket 22 includes two side support brackets 19 and a crossbeam 20 that fixes the side support brackets 19 together. Several ribs 21 are welded and fixed at the connection to improve the overall structural stability and strength after fixing. It should be noted that the structural shapes of the crossbeam 20, rib plate 21, and side support frame 19 can have various different structural forms, such as... Figure 1 and 6 .

[0026] In a preferred embodiment, the support bracket 22 further includes a rotating shaft 31. One end of the rotating shaft 31 is fixed to the side support frame 19, and the other end is rotatably disposed in the slider 15 through a matching bearing. The synchronous wheel 14 is fixed to the rotating shaft 31 by a key interference fit. On the one hand, the synchronous wheel 14 forms a coupling force with the rack 23, thereby generating a torque to drive the support bracket 22 when the drive slider 17 descends. This causes the support bracket 22 to drive the electrically heated crucible 32 to rotate to reduce the gate height during unloading. On the other hand, the cooperation between the synchronous wheel 14 and the rack 23 further restricts the degree of freedom of the support bracket 22, improving the stability of the equipment during movement.

[0027] In a preferred embodiment, a bracket connecting plate 25 with screw holes is welded and fixed to the inner wall of the side support frame 19, and the crucible ring frame 33 and the bracket connecting plate 25 are fixedly connected by bolts.

[0028] In a preferred embodiment, a reinforcing rib 30 is welded and fixed between the side support frame 19 and the bracket connecting plate 25 to improve the connection strength of the equipment structure and reduce the thickness of the connecting plates through structural mechanics improvement.

[0029] It should be emphasized that the embodiments described in this invention are illustrative rather than limiting. Therefore, this invention is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this invention also fall within the scope of protection of this invention.
