Description

Technical Field

[0001] This application relates to the field of silicon steel annealing technology, and in particular to the trolley structure for oriented silicon steel annealing furnaces. Background Technology

[0002] In the production process of grain-oriented silicon steel, annealing is a crucial step, and bogie-type annealing furnaces are one of the commonly used pieces of equipment. In existing technologies, when using a bogie-type annealing furnace, the bogie and the workpiece enter the furnace together for heating. This method has several drawbacks. Firstly, the bogie itself is not the object of heating, but it is heated along with the workpiece, which undoubtedly consumes a large amount of additional energy, leading to energy waste and increasing production costs.

[0003] On the other hand, during the annealing of grain-oriented silicon steel, the furnace temperature typically reaches a high level of 600–900 degrees Celsius. Such high temperatures negatively impact the overall structure of the trolley, causing thermal deformation of components such as the trolley frame, reducing its structural strength and stability. Simultaneously, the high temperature accelerates the aging and damage of internal components of the drive source that moves the trolley, such as the motor, leading to performance degradation or even malfunction. This significantly affects the trolley's service life and increases maintenance and replacement costs. Therefore, a trolley structure for grain-oriented silicon steel annealing furnaces has been proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a trolley structure for an annealing furnace of oriented silicon steel, so as to solve the problems mentioned in the background art.

[0005] The trolley structure for the annealing furnace of grain-oriented silicon steel provided in this application adopts the following technical solution:

[0006] A trolley structure for an annealing furnace of oriented silicon steel includes a base and a furnace body and trolley plate installed on the base. A support platform is fixedly connected to the inner wall of the furnace body, and two clearance grooves are opened on the outer wall of the support platform. Two guide rails are fixedly connected to the top outer wall of the base.

[0007] The bottom outer wall of the trolley plate is equipped with multiple movable wheels, which are respectively rolledly connected to two guide rails. The bottom outer wall of the trolley plate is equipped with a drive assembly that drives the multiple movable wheels to rotate synchronously. The top outer wall of the trolley plate is fixedly connected to two lifting rings by multiple telescopic rods. A placement platform is installed above the two lifting rings. An oriented silicon steel coil is placed above the placement platform. A lifting mechanism is installed on the top outer wall of the trolley plate.

[0008] The lifting mechanism includes multiple inclined blocks and multiple directional wheels. Every two directional wheels are rotatably connected to the bottom outer wall of the lifting ring. The multiple directional wheels abut against the multiple inclined blocks respectively. A slide rail is fixedly connected to the top outer wall of the trolley plate. A slider is slidably connected to the inner wall of the slide rail. The multiple inclined blocks are fixedly connected to the top outer wall of the slider.

[0009] Preferably, the lifting mechanism further includes a cylinder that is fixedly mounted on the outer wall of one end edge of the trolley plate by a mounting bracket, and the output end of the cylinder passes through the mounting bracket and is fixedly connected to the outer wall of one end of the slider.

[0010] Preferably, the top outer wall of the lifting ring is fixedly connected with multiple positioning blocks, and the bottom outer wall of the placement platform is fixedly connected with multiple positioning cylinders. The positioning cylinders are inserted into the positioning blocks, and the outer diameter of the positioning cylinders is smaller than the inner diameter of the clearance groove.

[0011] Preferably, the drive assembly includes a drive shaft, a reducer, and a drive motor. The two ends of the two drive shafts are fixedly connected to the axles of a plurality of moving wheels, the two output shafts of the reducer are fixedly connected to the outer wall of the middle section of the drive shaft, and the output shaft of the drive motor is fixedly connected to the input shaft of the reducer.

[0012] Preferably, the outer wall of the feed inlet of the base has two symmetrically slidingly connected sealing doors, and the outer walls of the two sealing doors are fixedly connected with racks.

[0013] Preferably, the outer wall of the furnace body near the feed inlet is rotatably connected to two rotating shafts via a shaft frame. The rotating shafts are fixedly connected to a second gear near the top outer wall, and the two second gears mesh with two second racks respectively.

[0014] Preferably, racks are fixedly connected to the outer walls on both sides of the trolley plate, and gears are fixedly connected to the outer wall near the bottom of the rotating shaft, with the two gears meshing with the two racks respectively.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] 1. By using a lifting mechanism and a feeding / discharging method, the trolley does not enter the furnace body during the annealing process. This avoids the trolley itself being heated inside the furnace, thus eliminating a large amount of extra energy consumed due to the heating of the trolley and effectively reducing energy waste. At the same time, the opening and closing of the furnace door is linked with the movement of the trolley. The furnace door is automatically opened and closed when the trolley enters or exits the furnace body, reducing the loss of heat inside the furnace and further reducing energy consumption. In actual production, long-term use of this trolley structure can significantly reduce energy costs, improve the economic efficiency of production, and avoid the problem of increased production costs due to energy waste.

[0017] 2. Because the trolley is not located inside the furnace during annealing, it successfully avoids the high-temperature environment of 600-900 degrees Celsius inside the furnace. This prevents the overall structure of the trolley, such as the frame, from thermally deforming due to high temperatures, thus maintaining the strength and stability of the structure. At the same time, the drive source that moves the trolley, such as the motor, is also not affected by high temperatures, avoiding the accelerated aging and damage of internal components due to high temperatures. Therefore, this trolley structure can greatly extend the service life of the trolley, reduce the frequency of equipment maintenance and replacement, thereby reducing equipment maintenance costs and improving the continuity and stability of production.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a trolley structure for an annealing furnace of grain-oriented silicon steel. (Refer to...) Figure 1-5 The trolley structure for annealing furnace of oriented silicon steel mainly includes a base 1, a furnace body 2 and a trolley plate 6.

[0026] The furnace body 2 is mounted above the base 1, and a support platform 3 is fixedly connected to its inner wall. Two clearance grooves 4 are opened on the outer wall of the support platform 3 for cooperation with subsequent components. Two guide rails 5 are fixedly connected to the top outer wall of the base 1 to guide the movement of the trolley plate 6.

[0027] The trolley plate 6 is located on the base 1, and multiple movable wheels 7 are installed on its bottom outer wall. These movable wheels 7 are respectively rolledly connected to two guide rails 5 to ensure that the trolley plate 6 can move smoothly along the guide rails 5. The bottom outer wall of the trolley plate 6 is also equipped with a drive assembly that drives the multiple movable wheels 7 to rotate synchronously. The drive assembly consists of a transmission shaft 8, a reducer 9, and a drive motor 10. The two ends of the two transmission shafts 8 are fixedly connected to the axles of the multiple movable wheels 7, respectively. The two output shafts of the reducer 9 are fixedly connected to the middle section of the outer wall of the transmission shaft 8, and the output shaft of the drive motor 10 is fixedly connected to the input shaft of the reducer 9. Power is provided by the drive motor 10, and after being reduced and increased in torque by the reducer 9, the transmission shaft 8 is driven to rotate, thereby realizing the synchronous rotation of the multiple movable wheels 7 and driving the trolley plate 6 to move.

[0028] The top outer wall of the trolley plate 6 is fixedly connected to two lifting rings 15 by multiple telescopic rods 14. A placement platform 18 is installed above the two lifting rings 15 for placing oriented silicon steel coils 20. A lifting mechanism is installed on the top outer wall of the trolley plate 6. This lifting mechanism includes multiple inclined blocks 13, multiple directional wheels 17, a slide rail 11, a slider 12, a mounting bracket 21, and a cylinder 22. Every two directional wheels 17 are rotatably connected to the bottom outer wall of the lifting rings 15. The multiple directional wheels 17 abut against the multiple inclined blocks 13 respectively. The slide rail 11 is fixedly connected to the top outer wall of the trolley plate 6, and the slider 12 is slidably connected to the inner wall of the slide rail 11. The multiple inclined blocks 13 are fixedly connected to the top outer wall of the slider 12. The cylinder 22... Mounting bracket 21 is fixedly installed on the outer wall of one edge of the trolley plate 6. Its output end passes through mounting bracket 21 and is fixedly connected to the outer wall of one end of slider 12. When cylinder 22 is activated, it pushes slider 12 to slide on slide rail 11, and inclined block 13 moves accordingly. Through the abutment action of inclined block 13 and directional wheel 17, lifting ring 15 is raised or lowered, thereby realizing the lifting or lowering of placement platform 18 and oriented silicon steel coil 20. In addition, multiple positioning blocks 16 are fixedly connected to the top outer wall of lifting ring 15, and multiple positioning cylinders 19 are fixedly connected to the bottom outer wall of placement platform 18. Positioning cylinders 19 are inserted into positioning blocks 16, and the outer diameter of positioning cylinder 19 is smaller than the inner diameter of clearance groove 4 to ensure accurate installation and positioning of placement platform 18.

[0029] Two sealing doors 24 are symmetrically slidably connected to the outer wall of the feed inlet of the base 1. Two racks 25 are fixedly connected to the outer walls of the two sealing doors 24. Two rotating shafts 27 are rotatably connected to the outer wall of the furnace body 2 near the feed inlet via a shaft bracket 26. Gears 28 are fixedly connected to the outer wall of the rotating shafts 27 near the top. The two gears 28 mesh with the two racks 25 respectively. Racks 23 are fixedly connected to the outer walls of both sides of the trolley plate 6. Gears 29 are fixedly connected to the outer wall of the rotating shafts 27 near the bottom. Gear 29 meshes with two racks 23. When the trolley plate 6 moves, rack 23 drives gear 29 to rotate, which in turn causes shaft 27 to rotate. Through the meshing of gear 28 and rack 25, the sealing door 24 is opened and closed. It is worth noting that rack 25 is slightly longer than rack 23. When gear 29 finishes meshing with rack 23 and disengages, it ensures that the meshing state of gear 28 and rack 25 can just fully open the two sealing doors 24.

[0030] The implementation principle of the trolley structure for the annealing furnace of oriented silicon steel in this application embodiment is as follows: the lifting mechanism on the trolley is initially in the highest lifting height state. At this time, the placement platform 18 is in a higher position under the action of the telescopic rod 14 and the lifting ring 15, and the oriented silicon steel coil 20 is stably placed on the placement platform 18.

[0031] Cart movement and furnace door opening: Start the drive motor 10. The power of the drive motor 10 is transmitted to the transmission shaft 8 through the reducer 9, which drives multiple moving wheels 7 to roll synchronously on the guide rail 5, so that the car plate 6 moves towards the feed port of the furnace body 2. During the movement of the car plate 6, the rack 23 on both sides drives the gear 29 to rotate, which in turn causes the rotating shaft 27 to rotate. Through the meshing of the gear 28 and the rack 25, the two sealing doors 24 are driven to slide open to both sides. When the car enters the furnace body 2, the rack 23 and the gear 29 disengage, and the two sealing doors 24 no longer move.

[0032] Silicon steel coil placement: When annealing feeding is required, the trolley drives the placement platform 18 and the oriented silicon steel coil 20 into the furnace body 2 through the lifting mechanism. The oriented silicon steel coil 20 and the placement platform 18 are accurately placed on the support platform 3. At the same time, multiple positioning cylinders 19 and the clearance grooves 4 are inserted to ensure that the placement platform 18 is accurately positioned on the support platform 3.

[0033] Lifting mechanism descent and trolley retraction: Start cylinder 22 to reverse its action. The output end of cylinder 22 pulls slider 12 to slide in the opposite direction on slide rail 11. Slider 12 drives inclined block 13 to move. Directional wheel 17 rolls along the inclined surface of inclined block 13, thereby causing lifting ring 15 to descend. As lifting ring 15 descends, positioning block 16 separates from positioning cylinder 19. At this time, placement platform 18 and oriented silicon steel coil 20 remain stably on bearing platform 3. Start drive motor 10 again to make trolley plate 6 exit from base 1. At the same time, during the exit of trolley plate 6, furnace door opening and closing structure reverses its action. Rack 23 re-meshes with gear 29, causing two sealing doors 24 to slide and close in opposite directions, ensuring the sealing of furnace body 2. In this way, oriented silicon steel coil 20 is fed into furnace body 2 for annealing, ensuring that the trolley is not located in furnace body 2 during annealing, avoiding damage to the trolley from high temperature.

[0034] When the annealing is complete and the material needs to be removed, start the drive motor 10 to move the trolley plate 6 into the furnace body 2. During the movement of the trolley plate 6, the rack 23 on both sides drives the gear 29 to rotate, which in turn causes the shaft 27 to rotate. Through the meshing of the gear 28 and the rack 25, the two sealing doors 24 are driven to slide open to both sides.

[0035] When the trolley enters the furnace body 2, the cylinder 22 is activated to make it move in the forward direction. The output end of the cylinder 22 pushes the slider 12 to slide on the slide rail 11. The slider 12 drives the inclined block 13 to move. The directional wheel 17 rolls along the inclined surface of the inclined block 13, causing the lifting ring 15 to rise. As the lifting ring 15 rises, the positioning block 16 gradually rises and accurately inserts into the positioning cylinder 19, thereby connecting the placement platform 18 and the lifting ring 15 into a whole.

[0036] Trolley withdrawal and furnace door closing: Restart the drive motor 10 to move the trolley. Since the placement platform 18 and the lifting ring 15 are connected, the trolley can drive the placement platform 18 and the oriented silicon steel coil 20 to be unloaded from the furnace body 2 when it moves. After the trolley is completely withdrawn from the furnace body 2, the furnace door opening and closing structure moves in the opposite direction during the withdrawal of the trolley plate 6. The two sealing doors 24 slide to close in opposite directions to ensure the sealing of the furnace body 2. Subsequently, the oriented silicon steel coil 20 is removed from the placement platform 18 through corresponding operations to complete the entire material unloading process.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
