Description

Technical Field

[0001] This utility model relates to the field of lifting devices, and in particular to a lifting device for an electroslag remelting production system. Background Technology

[0002] In modern industrial production, electroslag remelting technology, as an advanced process that can significantly improve the quality of metallic materials, is widely used in the preparation of high-end materials such as special steel and high-temperature alloys. Among these processes, the lifting device used in the electroslag remelting production system plays a crucial role. It is responsible for precisely controlling the position of the consumable electrode rod, which is decisive for ensuring the stability of the electroslag remelting process and the quality of the product.

[0003] Currently, the clamping and fixing structures used in lifting devices in common electroslag remelting production systems are relatively traditional. Most existing equipment relies on clamps of fixed dimensions to fix the consumable electrode rod. The technical principle is to use a specific shape and size of the clamp to fit tightly against the suitable consumable electrode rod, and then use mechanical fastening methods, such as bolt tightening, to fix the electrode rod. In actual operation, a motor drives the relevant transmission components, causing the clamp holding the electrode rod to move up and down.

[0004] However, this traditional clamping device has obvious limitations. It can only be used with consumable electrode rods of a specific size. When encountering electrode rods of different specifications, different chucks need to be replaced. This process is extremely cumbersome. Not only do operators need to spend a lot of time disassembling the original chuck and installing the new chuck, but it also involves fine-tuning the installation position of the chuck. This seriously affects production efficiency and greatly limits the adaptability of the equipment to diverse production needs. Therefore, a lifting device for electroslag remelting production systems is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lifting device for an electroslag remelting production system, which aims to improve the problem that the clamping devices of traditional equipment can only be adapted to consumable electrode rods of a specific size. Different clamps need to be replaced for electrode rods of different specifications, resulting in cumbersome and time-consuming operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lifting device for an electroslag remelting production system includes a lifting platform, a support platform fixedly connected to one side of the lifting platform, a fixing component provided on the inner wall of the support platform, a base plate fixedly connected to the other side of the lifting platform, and a stabilizing component provided on the top of the base plate;

[0008] The fixing assembly includes multiple arc-shaped clamps located on the inner wall of the support platform. A fixing ring is fixedly connected to the inner wall of the support platform. A transmission block is fixedly connected to one side of each arc-shaped clamp. A connecting strip is rotatably connected inside each transmission block. A rotating ring is fixedly connected to the bottom end of multiple connecting strips. A connecting ring is fixedly connected to the top end of multiple connecting strips. A rotating bar is rotatably connected inside each transmission block. The bottom of multiple rotating bars is fixedly connected to the top of the fixing ring. A pushing assembly is provided on the outer wall of the rotating ring.

[0009] As a further description of the above technical solution:

[0010] Each of the arc-shaped clamps has multiple rubber balls fixedly connected to its inner wall, and each of the rotating rings has a limiting groove inside, with the fixing ring engaging with the inner wall of the limiting groove.

[0011] As a further description of the above technical solution:

[0012] The pushing assembly includes a threaded rod located on the outer wall of the rotating ring. A fixing block is fixedly connected to the top of the fixing ring. The threaded rod is threadedly connected inside the fixing block. A connecting block is threadedly connected to the outer wall of the threaded rod. The connecting block is rotatably connected inside the rotating ring. A handle is fixedly connected to one end of the threaded rod.

[0013] As a further description of the above technical solution:

[0014] The stabilizing component includes multiple dampers located on top of the base plate, and a connecting plate is fixedly connected to the other side of the elevator.

[0015] As a further description of the above technical solution:

[0016] A plurality of connecting blocks 2 are fixedly connected to one side of the connecting plate, and a transmission block 2 is rotatably connected inside each connecting block 2.

[0017] As a further description of the above technical solution:

[0018] Each of the two transmission blocks is fitted with a protective cover on its outer wall, and a transmission block is fixedly connected to one side of each protective cover.

[0019] As a further description of the above technical solution:

[0020] Each of the three transmission blocks has a damper fixedly connected to one side, and the output end of each damper is fixedly connected to the second transmission block.

[0021] As a further description of the above technical solution:

[0022] Each of the transmission blocks three is rotatably connected to a connecting block three inside, and the bottoms of multiple connecting blocks three are fixedly connected to the top of the base plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the distance between multiple arc-shaped clamping plates is adjusted by pushing the component, thereby clamping and fixing the consumable electrode rod. This achieves the effect of targeted clamping and fixing of consumable electrode rods of different sizes, solving the problem that the clamping device of traditional equipment can often only be adapted to consumable electrode rods of specific sizes. Different clamps need to be replaced for electrode rods of different specifications, resulting in cumbersome and time-consuming operation, thus enhancing the applicability of the equipment.

[0025] 2. In this utility model, the vibration force generated by the equipment is accurately transmitted to the output end of the damper through the transmission block two, causing the damper to compress. Furthermore, the outer wall of the damper is protected by a protective cover, which achieves the effect of reducing the vibration force generated by the operation of the equipment. This solves the problem that traditional equipment generates a certain amplitude of vibration force during operation, which can easily cause the self-consumable electrode rod to shake, affecting the electroslag remelting effect. This enhances the stability of the equipment during operation. Attached Figure Description

[0034] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a lifting device for an electroslag remelting production system, comprising a lifting platform 1. The lifting platform 1 transmits the rotational motion of the internal motor output to a worm gear. The worm gear meshes with a worm wheel, and the rotation of the worm gear drives the worm wheel to rotate. The worm wheel is connected to a lead screw, and the rotational motion of the worm wheel is converted into the linear motion of the lead screw. The lead screw and the lifting platform are connected by a nut. As the lead screw moves linearly, the nut drives the lifting platform to achieve a smooth upward or downward movement along the guide rail. In this process, by controlling the forward and reverse rotation and the speed of the motor, the lifting direction and speed of the lifting platform 1 can be precisely controlled to meet the vertical displacement requirements of objects in different working scenarios. A support platform 2 is fixedly connected to one side of the lifting platform 1. The support platform 2 is used to support and fix the consumable electrode rod. A fixing component is provided on the inner wall of the support platform 2. The fixing component is used to clamp and adjust consumable electrode rods of different sizes. A base plate 3 is fixedly connected to the other side of the lifting platform 1. The base plate 3 is used to provide stable support. A stabilizing component is provided on the top of the base plate 3. The stabilizing component is used to reduce equipment vibration.

[0035] The fixing assembly includes multiple arc-shaped clamps 15, which are used to directly contact and clamp the consumable electrode rod. The multiple arc-shaped clamps 15 are located on the inner wall of the support platform 2. A fixing ring 4 is fixedly connected to the inner wall of the support platform 2, providing support and limiting. A transmission block 13 is fixedly connected to one side of each arc-shaped clamp 15, transmitting rotational motion. A connecting strip 14 is rotatably connected inside each transmission block 13, connecting the transmission block 13 and the rotating ring 7. A rotating ring 7 is fixedly connected to the bottom of the multiple connecting strips 14, driving the connecting strips 14 to rotate. A connecting ring 5 is fixedly connected to the top of the multiple connecting strips 14, enhancing structural stability. A rotating bar 12 is rotatably connected inside each transmission block 13, providing a rotation fulcrum. The bottom of the multiple rotating bars 12 is fixedly connected to the fixing ring. At the top of ring 4, a pushing assembly is provided on the outer wall of the rotating ring 7. The pushing assembly is used to drive the rotating ring 7 to rotate. Multiple rubber balls 16 are fixedly connected to the inner wall of each arc-shaped clamp 15. The rubber balls 16 are used to increase friction. A limiting groove 6 is opened inside each rotating ring 7. The limiting groove 6 is used to limit the movement trajectory of the rotating ring 7. The fixed ring 4 is engaged with the inner wall of the limiting groove 6. The pushing assembly includes a threaded rod 9. The threaded rod 9 is used to transmit rotational force. The threaded rod 9 is located on the outer wall of the rotating ring 7. A fixing block 8 is fixedly connected to the top of the fixed ring 4. The fixing block 8 is used to fix the threaded rod 9. The threaded rod 9 is threadedly connected inside the fixing block 8. A connecting block 10 is threadedly connected to the outer wall of the threaded rod 9. The connecting block 10 is used to connect the threaded rod 9 and the rotating ring 7. The connecting block 10 is rotatably connected inside the rotating ring 7. A handle 11 is fixedly connected to one end of the threaded rod 9. The handle 11 is used to manually rotate the threaded rod 9.

[0036] Reference Figure 2 and Figure 5 The stabilizing component includes multiple dampers 20, which absorb vibration energy. These dampers 20 are located on the top of the base plate 3. A connecting plate 17 is fixedly connected to the other side of the elevator 1, transmitting vibration. Multiple connecting blocks 18 are fixedly connected to one side of the connecting plate 17, connecting blocks 18 connecting transmission blocks 19. Each connecting block 18 has a rotatably connected transmission block 19 inside, transmitting vibration force. Each transmission block 19 has a protective sleeve on its outer wall. Cover 22, protective cover 22 is used to protect damper 20. Each protective cover 22 has a transmission block 3 21 fixedly connected to one side. Transmission block 3 21 is used to connect damper 20 and protective cover 22. Each transmission block 3 21 has a damper 20 fixedly connected to one side. The output end of each damper 20 is fixedly connected to transmission block 2 19. Each transmission block 3 21 has a connecting block 3 23 rotatably connected inside. Connecting block 3 23 is used to provide a rotation fulcrum. The bottom of multiple connecting blocks 3 23 is fixedly connected to the top of base plate 3.

[0037] Working principle: During the clamping and fixing of the consumable electrode rod, the inner wall of the arc-shaped clamping plate 15 is moved to the outer wall of the consumable electrode rod. Then, the handle 11 is rotated, and the threaded connection between the threaded rod 9 and the connecting block 10 drives the rotating ring 7 to rotate. Since the limiting groove 6 inside the rotating ring 7 is engaged with the outer wall of the fixing ring 4, the position of the rotating ring 7 is limited. While rotating, the rotating ring 7 drives the transmission block 13 to rotate around the rotating bar 12 as the center through the connecting bar 14 to adjust the distance between the multiple arc-shaped clamping plates 15 until the arc-shaped clamping plate 15 is moved to the consumable electrode rod. The outer wall clamps and fixes the consumable electrode rod. At the same time, the locking feature between the threaded rod 9 and the connecting block 10 is used to fix the position of the arc-shaped clamp 15. The rubber ball 16 is used to enhance the friction between the arc-shaped clamp 15 and the consumable electrode rod, which achieves the effect of targeted clamping and fixing of consumable electrode rods of different sizes. This solves the problem that the clamping device of traditional equipment can only be adapted to consumable electrode rods of specific sizes. For electrode rods of different specifications, different clamps need to be replaced or complex adjustments need to be made, which leads to cumbersome and time-consuming operation. This enhances the applicability of the equipment.

[0038] During equipment use, a certain degree of vibration is generated. This vibration force is transmitted through the connecting plate 17 to drive the transmission block 19 inside the connecting block 18 to slide inside the protective cover 22, accurately transmitting this vibration force to the output end of the damper 20, causing the damper 20 to compress, thereby reducing the vibration force generated by the equipment. The protective cover 22 protects the outside of the damper 20, preventing external dust from damaging the damper 20. While the damper 20 is compressed, it drives the transmission block 21 to rotate around the connecting block 23, ultimately achieving the effect of reducing the vibration force generated by the equipment operation. This solves the problem that traditional equipment generates a certain amplitude of vibration force during operation, which can easily cause the self-consumable electrode rod to shake, affecting the electroslag remelting effect, and enhances the stability of the equipment during operation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
