Description

Technical Field

[0001] This utility model relates to the field of fused zirconia-corundum brick production technology, specifically a transfer device for the production and transportation of fused zirconia-corundum bricks. Background Technology

[0002] Electrofused zirconia bricks, also known as electrofused zirconia-corundum bricks, are high-temperature refractory materials made from zircon sand (65% zirconium oxide, 34% silicon dioxide) and alumina as the main raw materials, melted in an electric arc furnace and then cast. Their name originates from the abbreviation of the Al2O3-ZrO2-SiO2 ternary chemical composition. They are classified into models such as AZS-33#, AZS-36#, and AZS-41# according to ZrO2 content. The petrographic structure consists of a eutectic of corundum and zirconium clastic phases, with a glassy phase filling the intergranular spaces. The transfer equipment used in the production and transportation of electrofused zirconia-corundum bricks is mainly used for short-distance handling and transfer between processes within the workshop, or for the temporary stacking and transportation of finished and semi-finished products. It needs to be adapted to the physical properties of the electrofused zirconia-corundum bricks and the requirements of the production scenario. Its core functions are to improve transportation efficiency, ensure material safety, and reduce the intensity of manual labor. The existing transfer equipment for the production and transportation of fused zirconia-corundum bricks involves manually tightening the bricks by rotating the bolts on both sides of the vehicle platform, then using ropes, steel straps, or nylon straps to tie the bricks to the vehicle platform, and finally using the handles to transport the fused zirconia-corundum bricks by the wheels. The existing transfer equipment for the production and transportation of fused zirconia-corundum bricks has the following problems: When producing and transporting fused zirconia-corundum bricks, the bolt tightening and rope binding to fix the fused zirconia-corundum bricks is cumbersome and laborious, and the bricks are prone to loosening and damage if too tight, resulting in poor fixing effect. Therefore, we propose a transfer equipment for the production and transportation of fused zirconia-corundum bricks. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a transfer device for the production and transportation of fused zirconia-corundum bricks. During the production and transportation of fused zirconia-corundum bricks, the device fixes the bricks by mechanical self-locking and three-sided limiting, which is simple and labor-saving, prevents loosening and over-tightening, avoids brick damage, and has a better fixing effect. It can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for the production and transportation of fused zirconia corundum bricks, including a vehicle platform, with symmetrical wheels rotatably connected to the lower rear end of the vehicle platform via a rotating shaft, a guardrail at the lower end of the vehicle platform, and a fixing mechanism. The fixing mechanism includes a strip cover, threaded rods, internal threaded cylinders, and fixing rods. The strip cover is located in the middle of the rear end of the vehicle plate. The left and right ends of the strip cover are rotatably connected to evenly distributed threaded rods. The opposite ends of the threaded rods are threaded to internal threaded cylinders, and the opposite ends of the internal threaded cylinders are fixedly connected to fixing rods. The left and right ends of the vehicle plate are respectively provided with limiting holes corresponding to the internal threaded cylinders. The inner walls of the limiting holes are slidably connected to the outer walls of the laterally adjacent internal threaded cylinders. During the production and transportation of fused zirconia corundum bricks, the fused zirconia corundum bricks are fixed by mechanical self-locking and three-sided limiting, which is simple and labor-saving, prevents loosening and over-tightening, avoids brick damage, and provides better fixing effect.

[0005] Furthermore, a microcontroller is provided in the middle of the upper part of the vehicle panel. The input terminal of the microcontroller is electrically connected to an external power source to provide electrical connections for various electrical appliances.

[0006] Furthermore, the fixing mechanism also includes a rotating shaft, a first bevel gear, and a second bevel gear. The rotating shaft is rotatably connected between the upper and lower inner walls of the strip cover. Two horizontally adjacent threaded rods are fixedly connected by adapter columns. The middle part of the adapter column is fixedly fitted with a second bevel gear. The outer surface of the rotating shaft is fixedly fitted with evenly distributed first bevel gears. The first bevel gears mesh with the horizontally adjacent second bevel gears to provide a transmission connection.

[0007] Furthermore, the fixing mechanism also includes a drive assembly, which includes a worm and a worm wheel. The worm is rotatably connected to the upper side between the left and right inner walls of the strip cover, and the worm wheel is fixedly sleeved on the upper side of the outer surface of the rotating shaft. The worm and the worm wheel are meshed and connected to provide a transmission connection.

[0008] Furthermore, the drive assembly also includes a motor, which is located on the upper side of the left end of the strip cover. The right end of the motor's output shaft is fixedly connected to the left end of the worm gear, and the input end of the motor is electrically connected to the output end of the microcontroller to provide fixed drive.

[0009] Furthermore, an angle sensor is provided on the upper side of the right end of the strip cover. The middle part of the counting shaft of the angle sensor is fixedly connected to the right end of the worm gear. The angle sensor is bidirectionally electrically connected to the microcontroller to provide angle monitoring.

[0010] Furthermore, the upper end of the vehicle platform is provided with symmetrical handles, and the upper rear end of the vehicle platform is provided with symmetrical support legs.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This transfer equipment for the production and transportation of fused zirconia-corundum bricks has the following advantages: Driven by a motor, the rotating shaft rotates through a worm gear and a meshing worm wheel. The rotating shaft then rotates a threaded rod through a bevel gear and a meshing bevel gear. As the threaded rod rotates, it drives a fixed rod to move in opposite directions through an internal threaded cylinder, thus clamping the fused zirconia-alumina brick. During the production and transportation of the fused zirconia-alumina brick, mechanical self-locking and three-sided limiting fixation secure the brick, which is simple and labor-saving, prevents loosening and over-tightening, avoids brick breakage, and provides a better fixing effect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This embodiment provides a technical solution: a transfer device for the production and transportation of fused zirconia corundum bricks, including a car platform 1, with symmetrical wheels 2 rotatably connected to the lower rear end of the car platform 1 via a rotating shaft, a guardrail 3 at the lower end of the car platform 1, and a fixing mechanism 4, a microcontroller 6 at the middle of the upper end of the car platform 1, the input end of the microcontroller 6 being electrically connected to an external power source, symmetrical handles 7 at the upper end of the car platform 1, and symmetrical support legs 8 at the upper rear end of the car platform 1. Then, by holding the two handles 7, the vehicle is transported by the wheels 2. Fixing mechanism 4 includes a strip cover 41, threaded rods 42, internal threaded cylinders 43, and fixing rods 44. The strip cover 41 is located in the middle of the rear end of the vehicle plate 1. Threaded rods 42 are rotatably connected to both ends of the strip cover 41, and internal threaded cylinders 43 are threadedly connected to opposite ends of the threaded rods 42. Fixing rods 44 are fixedly connected to opposite ends of the internal threaded cylinders 43. Limiting holes corresponding to the internal threaded cylinders 43 are respectively opened at both ends of the vehicle plate 1. The inner walls of the limiting holes are slidably connected to the outer walls of the laterally adjacent internal threaded cylinders 43. (A bellows is fixedly connected between the right edge of the left internal threaded cylinder 43 and the left edge of the strip cover 41, and between the right edge of the strip cover 41 and the left edge of the right internal threaded cylinder 43.) The threaded tubes are respectively sleeved on the outside of the threaded rods 42 to protect them from dust and ensure their sealing and lubrication. The fixing mechanism 4 also includes a rotating shaft 45, a bevel gear 46, and a bevel gear 47. The rotating shaft 45 is rotatably connected between the upper and lower inner walls of the strip cover 41. Two horizontally adjacent threaded rods 42 are fixedly connected by adapter pins. The middle part of the adapter pins is fixedly sleeved with bevel gears 47. The outer surface of the rotating shaft 45 is fixedly sleeved with evenly distributed bevel gears 46. The bevel gears 46 mesh with the horizontally adjacent bevel gears 47. The fixing mechanism 4 also includes a drive assembly 48, which includes a worm gear 481 and a worm wheel 482. The worm gear 481 is rotatably connected to the upper and lower inner walls of the strip cover 41. On the upper side between the left and right inner walls of the strip cover 41, a worm gear 482 is fixedly sleeved on the upper side of the outer surface of the rotating shaft 45. The worm 481 is meshed with the worm gear 482. The drive assembly 48 also includes a motor 483, which is located on the upper side of the left end of the strip cover 41. The right end of the output shaft of the motor 483 is fixedly connected to the left end of the worm 481. The input end of the motor 483 is electrically connected to the output end of the microcontroller 6. An angle sensor 5 is provided on the upper side of the right end of the strip cover 41. The middle part of the counting shaft of the angle sensor 5 is fixedly connected to the right end of the worm 481. The angle sensor 5 is bidirectionally electrically connected to the microcontroller 6. During the production and transportation of fused zirconia corundum bricks, the vehicle platform 1 is first laid flat, supported by the wheels 2 and the outriggers 8. Then, the fused zirconia corundum bricks are placed on the upper end of the vehicle platform 1. The operation of motor 483 is controlled by microcontroller 6. The output shaft of motor 483 drives worm gear 481 to rotate, which in turn drives worm wheel 482 to rotate. Worm wheel 482 then drives rotating shaft 45 to rotate. Bevel gear 46 of rotating shaft 45 meshes with bevel gear 47 on the adapter post of transverse threaded rod 42. The vertical rotation of rotating shaft 45 is converted into horizontal rotation of threaded rod 42. (Two adjacent threaded rods 42 are connected by an adapter post to ensure synchronous rotation.) When threaded rod 42 rotates, the internal threaded cylinder 43, which is threaded to it, is guided by the limiting hole of the vehicle plate 1 and moves laterally along the axis of threaded rod 42. Since the thread directions of the left and right threaded rods 42 are symmetrical, the internal threaded cylinder 43 will drive the fixed rod 44 to move towards each other.This achieves stable clamping of the fused zirconia-corundum brick. Angle sensor 5 detects the rotation angle of the worm gear 481 in real time and outputs the angle signal to the microcontroller 6. If the worm gear 481 rotates 360°, the threaded rod 42 will rotate 360° through the transmission of the worm wheel 482, rotating shaft 45, bevel gear one 46, and bevel gear two 47. The axial movement distance will be exactly equal to one thread pitch. For example, with a thread pitch of 1 cm, one rotation will move 1 cm in either direction. If the actual clamping distance does not reach the target value, the microcontroller 6 continues to control the motor 483. If the target value is reached, the microcontroller 6 issues a stop signal to avoid over-clamping damaging the brick or insufficient clamping causing fixing failure.

[0016] The working principle of the transfer equipment for the production and transportation of fused zirconia-corundum bricks provided by this utility model is as follows: During the production and transportation of fused zirconia-corundum bricks, the vehicle platform 1 is first laid flat, supported by wheels 2 and outriggers 8. Then, the fused zirconia-corundum bricks are placed on the upper end of the vehicle platform 1. Next, the motor 483 is operated by the microcontroller 6. The output shaft of the motor 483 drives the worm gear 481 to rotate, which in turn drives the meshing worm wheel 482 to rotate. The worm wheel 482 then drives the rotating shaft 45 to rotate. The bevel gear 46 of the rotating shaft 45 meshes with the bevel gear 47 on the adapter post of the transverse threaded rod 42. The vertical rotation of the rotating shaft 45 is converted into the horizontal rotation of the threaded rod 42. (Two adjacent threaded rods 42 are connected by an adapter post to ensure synchronous rotation.) When the threaded rod 42 rotates, the internally threaded cylinder 43, which is threaded to it, is guided by the limiting hole of the vehicle platform 1 and moves along the thread... The rod 42 moves laterally in the axial direction. Since the thread directions of the threaded rods 42 on the left and right sides are symmetrical, the internal threaded cylinder 43 will drive the fixed rod 44 to move towards each other, thereby achieving stable clamping of the fused zirconia corundum brick. The angle sensor 5 detects the rotation angle of the worm 481 in real time and outputs the angle signal to the microcontroller 6. If the worm 481 rotates 360°, the threaded rod 42 will rotate 360° through the transmission of the worm wheel 482, the rotating shaft 45, the first bevel gear 46 and the second bevel gear 47. Then the axial movement distance is exactly equal to 1 thread pitch. For example, if the thread pitch is 1 cm, the movement is 1 cm towards or away from each other in one rotation. If the actual clamping distance does not reach the target value, the microcontroller 6 continues to control the motor 483 to run. If the target value is reached, the microcontroller 6 sends a stop signal to avoid over-clamping and damaging the brick or insufficient clamping and failure of fixation. Then, hold the two handles 7 and transport it through the wheels 2.

[0017] It is worth noting that in the above embodiments, the motor 483 and the angle sensor 5 disclosed can be YS8024 and WDD35D4 respectively. The microcontroller 6 controls the operation of the motor 483 and the angle sensor 5 using methods commonly used in the prior art.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
