[0002] In the low-pressure casting production process, the holding furnace, as the core equipment for storing and supplying molten aluminum, requires frequent furnace changing operations to ensure production continuity.

[0003] Traditional furnace changing methods rely heavily on manual labor and simple handling devices, which presents numerous technical challenges: poor stability of molten aluminum transfer during furnace changing, leading to leaks and splashes that not only waste raw materials but also pose significant safety hazards; manual operation results in low furnace changing efficiency, with lengthy switching times between empty and full furnaces, impacting overall production rhythm; insufficient precision in the connection between the holding furnace and casting equipment, resulting in poor furnace mouth sealing, causing molten aluminum to lose temperature and decrease in purity, thus affecting casting quality; and the lack of real-time monitoring of the holding furnace status during furnace changing makes it impossible to detect abnormalities such as molten aluminum leakage in a timely manner, potentially leading to equipment damage or safety accidents.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a furnace changing system based on automated guided transport, such as... Figure 1-10 As shown, the furnace changing system based on automatic guided transport includes: a base plate 1; symmetrically mounted traveling wheels 3 below the base plate 1; a platform plate 7 fixed on the base plate 1 via a connecting seat 6; a guiding mechanism provided on the platform plate 7 for guiding the support seat 10 carrying the furnace body 40 to the platform plate 7, wherein the bottom of the support seat 10 is symmetrically provided with guide grooves; and a traveling mechanism provided on the base plate 1 for driving the traveling wheels 3 to travel.

[0021] In this embodiment, during use, the first guide plate 8 of the guiding mechanism first engages with the guide groove at the bottom of the support seat 10 to guide the support seat 10 of the furnace body 40 onto the platform plate 7, thus achieving the initial positioning of the furnace body 40. Subsequently, the traveling mechanism is activated, which drives the shaft 2 to rotate. The shaft 2 drives the traveling wheel 3 to move along the track of the casting system base, so that the base plate 1, together with the platform plate 7 and the furnace body 40, moves towards the furnace changing point. Once the base plate 1 reaches the furnace changing point, the traveling mechanism stops operating, and the base plate 1 is fixed in place by the positioning structure to ensure that it does not shift during the furnace changing process. Afterwards, the furnace body 40 can be docked with the casting equipment. Once docking is complete, subsequent casting production processes can begin.

[0022] The guiding mechanism can effectively guide the support seat 10 and the furnace body 40, making it easy for the furnace body 40 to be quickly placed on the platform plate 7; the walking mechanism drives the base plate 1 and the furnace body 40 to move along the track, reducing manual handling and improving the convenience of the furnace changing process; the overall structure improves the stability of the aluminum liquid transfer process, reduces the probability of aluminum liquid leakage and splashing, reduces raw material waste, and reduces safety risks during the furnace changing process.

[0023] In a further preferred embodiment of the present invention, the guiding mechanism comprises: a first guide plate 8 symmetrically fixed on the platform plate 7, the first guide plate 8 being adapted to the guide groove for guiding the support seat 10; a support seat 10 slidably mounted on the first guide plate 8, the top of the support seat 10 being fixedly connected to the furnace base; and a second guide plate 9 symmetrically arranged on the platform plate 7 and height adjustable, one end of the second guide plate 9 being engaged with the first guide plate 8.

[0024] In this embodiment, during use, the first guide plate 8 of the guiding mechanism first engages with the guide groove at the bottom of the support seat 10 to guide the support seat 10 of the furnace body 40 onto the platform plate 7, thus achieving the initial positioning of the furnace body 40. Subsequently, the traveling mechanism is activated, which drives the shaft 2 to rotate. The shaft 2 drives the traveling wheel 3 to move along the track of the casting system base, so that the base plate 1, together with the platform plate 7 and the furnace body 40, moves towards the furnace changing point. Once the base plate 1 reaches the furnace changing point, the traveling mechanism stops operating, and the base plate 1 is fixed in place by the positioning structure to ensure that it does not shift during the furnace changing process. Afterwards, the furnace body 40 can be docked with the casting equipment. Once docking is complete, subsequent casting production processes can begin. The guiding mechanism can effectively guide the support seat 10 and the furnace body 40, making it easy for the furnace body 40 to be quickly placed on the platform plate 7; the walking mechanism drives the base plate 1 and the furnace body 40 to move along the track, reducing manual handling and improving the convenience of the furnace changing process; the overall structure improves the stability of the aluminum liquid transfer process, reduces the probability of aluminum liquid leakage and splashing, reduces raw material waste, and reduces safety risks during the furnace changing process.

[0025] In a further preferred embodiment of the present invention, the walking mechanism comprises: bearing seats 37 symmetrically fixed at the bottom of the base plate 1; a shaft 2 rotatably mounted on the bearing seats 37, one end of the shaft 2 being fixedly connected to the corresponding walking wheel 3; a first motor 5 and a speed control box 4 fixed at the bottom of the base plate 1, the output shaft of the first motor 5 being fixedly connected to the input shaft of the speed control box 4 via a coupling; and the output shaft of the speed control box 4 being fixedly connected to the shaft 2 via a coupling.

[0026] In this embodiment, the first motor 5 is started first. The output shaft of the first motor 5 transmits power to the speed control box 4 through a coupling. The speed control box 4 adjusts the output speed to match the speed requirements of furnace transfer. After the speed control box 4 is adjusted, its output shaft drives the shaft 2 to rotate through the coupling. The shaft 2 rotates smoothly under the support of the bearing seat 37, which in turn drives the walking wheel 3, which is fixedly connected to the shaft 2, to rotate. The first motor 5 works in conjunction with the speed control box 4 to flexibly adjust the rotation speed of the walking wheels 3 to adapt to the transportation needs in different scenarios; the shaft 2 is rotatably installed through the bearing seat 37, which reduces the frictional resistance during rotation and makes the walking wheels 3 move more smoothly; the overall walking mechanism realizes power transmission through mechanical transmission, which has good operational stability and provides a guarantee for the smooth transportation of the furnace body 40, and helps to reduce the probability of aluminum liquid leakage and splashing.

[0027] In a further preferred embodiment of the present invention, a limiting mechanism is provided on the platform plate 7 for limiting the bearing seat 10, the furnace seat and the furnace body 40. The limiting mechanism includes: a guide block 12 fixed on the platform plate 7; a groove block 11 fixed on the bearing seat 10; a first push rod 13 slidably mounted on the guide block 12; an insert block 14 fixed on the first push rod 13, the top end of the insert block 14 being inserted into the groove block 11; and a second push rod 15 slidably mounted on the platform plate 7, the top end of the second push rod 15 being fixedly connected to the second guide plate 9 for adjusting the separation and engagement of the second guide plate 9 and the first guide plate 8.

[0028] In this embodiment, when in use, after the support seat 10 is placed in the preset position of the platform plate 7 by the guide mechanism, the first push rod 13 is slid along the guide block 12 by adjusting the relevant structure. The first push rod 13 drives the insertion block 14 to move synchronously, so that the top of the insertion block 14 is inserted into the groove block 11 on the support seat 10. At the same time, the second top rod 15 slides along the platform plate 7, causing the second guide plate 9 to adjust its height, so that the second guide plate 9 engages with the first guide plate 8, forming an auxiliary limit for the bearing seat 10; The insert block 14 cooperates with the groove block 11 to effectively limit the bearing seat 10 and reduce the displacement of the bearing seat 10 during furnace transfer; the second top rod 15 adjusts the second guide plate 9 to engage with the first guide plate 8, further improving the limiting stability; the overall limiting mechanism and the guiding mechanism cooperate to ensure the smooth transfer and subsequent docking of the furnace body 40, and help reduce the risk of aluminum liquid leakage.

[0029] In a further preferred embodiment of the present invention, the limiting mechanism further includes an adjustment mechanism disposed on the connecting seat 6 for adjusting the lifting and lowering of the first push rod 13 and the second push rod 15. The adjustment mechanism includes: an adjustment frame 17 disposed on the connecting seat 6 and adjustable laterally; a first support plate 18 and a second support plate 19 fixed to the adjustment frame 17 by bolts; and a first inclined groove 20 formed on the first support plate 18 and the second support plate 19, the first inclined groove 20 being adapted to the corresponding first push rod 13 and second push rod 15.

[0030] In this embodiment, during use, the adjustment frame 17 is driven to move laterally along the connecting seat 6 through the transmission structure, and the adjustment frame 17 drives the first support plate 18 and the second support plate 19, which are fixed by bolts, to move synchronously. During the movement of the first pallet 18 and the second pallet 19, the first inclined groove 20 on them slides relative to the corresponding first push rod 13 and second push rod 15, so that the first push rod 13 rises and falls along the guide block 12 and the second push rod 15 rises and falls along the platform plate 7. The adjusting frame 17 drives the first support plate 18 and the second support plate 19 to move synchronously, realizing the linkage adjustment of the first top rod 13 and the second top rod 15, simplifying the operation process; the first inclined groove 20 is adapted to the top rod to ensure that the lifting action is smooth and controllable; the overall adjusting mechanism provides stable power transmission for the limiting mechanism, improves the coordination of the limiting operation, and provides support for the stability of the furnace body 40 during the transfer process.

[0031] In a further preferred embodiment of the present invention, the adjusting mechanism further includes a transmission mechanism for controlling the lateral movement of the adjusting frame 17. The transmission mechanism includes: a mounting shell 21 fixed on the connecting seat 6; a screw 22 rotatably mounted in the mounting shell 21 via a bearing; an adjusting block 23 threaded onto the screw 22, the bottom end of the adjusting block 23 penetrating the mounting shell 21 and fixedly connected to the adjusting frame 17; a first guide rod 16 fixed on the connecting seat 6, the first guide rod 16 penetrating the adjusting frame 17; and a second motor 24 fixed in the mounting shell 21, the output shaft of the second motor 24 being fixedly connected to the screw 22 via a coupling.

[0032] In this embodiment, when in use, the second motor 24 is started, and the output shaft of the second motor 24 drives the screw 22 to rotate in the mounting housing 21 through the coupling, providing power for the lateral movement of the adjustment frame 17; The rotation of the screw 22 drives the adjusting block 23 to move axially along the screw 22 through the threaded engagement. The adjusting block 23 drives the adjusting frame 17 fixed thereto to move laterally in sync. The first guide rod 16 constrains the movement direction of the adjusting frame 17. The beneficial effects of this embodiment are that the second motor 24 provides stable power to the transmission mechanism, realizes the automated control of the adjustment frame 17, and reduces manual operation; the first guide rod 16 ensures that the adjustment frame 17 moves smoothly in the lateral direction and reduces offset error; the overall transmission mechanism operates reliably and responds smoothly through the cooperation of the motor and the screw, providing strong support for the linkage action of the adjustment mechanism and helping to improve the operation coordination of the furnace changing system.

[0033] In a further preferred embodiment of the present invention, a positioning mechanism is provided on the base plate 1 for positioning and preventing movement. The positioning mechanism includes: a slide rod 25 slidably mounted on the base plate 1; a positioning block 28 fixed on the bottom end of the slide rod 25; a limiting seat 27 disposed below the positioning block 28, the positioning block 28 being insertable into the limiting seat 27; a spring 26 sleeved on the slide rod 25; a pressure block 29 sleeved on the slide rod 25, the top of the pressure block 29 being fixedly connected to the adjusting frame 17; a second inclined groove 31 formed on the pressure block 29; and a ball bearing 30 embedded on the top end of the slide rod 25, the ball bearing 30 contacting the inner wall of the second inclined groove 31.

[0034] In this embodiment, when in use, the adjusting frame 17 moves laterally, causing the pressure block 29 to move synchronously. The second inclined groove 31 on the pressure block 29 slides relative to the ball 30 at the top of the slide rod 25, so that the slide rod 25 slides up and down along the base plate 1. When the base plate 1 reaches the preset position, the slide bar 25 drives the positioning block 28 to move down, and the positioning block 28 is inserted into the lower limit seat 27 to fix the base plate 1. When it is necessary to release the positioning, the adjusting frame 17 moves in the opposite direction, the spring 26 rebounds and drives the slide bar 25 to rise, and the positioning block 28 separates from the limit seat 27. The positioning block 28 works in conjunction with the limiting seat 27 to restrict the movement of the base plate 1 during the furnace changing process, thereby improving the stability of the furnace body 40 during transport and docking. The spring 26 works in conjunction with the second inclined groove 31 to make the positioning and unlocking actions smooth and continuous, without the need for additional manual operation. The overall positioning mechanism has a simple and reliable structure, which provides support for the safe operation of the furnace changing process and helps to reduce the risk of aluminum liquid leakage and splashing.

[0035] In a further preferred embodiment of the present invention, a first limiting block 38 is fixed at one end of the first guide rod 16, and a sliding hole adapted to the first guide rod 16 is provided on the adjusting frame 17.

[0036] In this embodiment, the adjusting frame 17 moves laterally under the drive of the transmission mechanism. The adjusting frame 17 forms a sliding fit with the first guide rod 16 through the sliding hole. The first guide rod 16 provides a guide trajectory for the movement of the adjusting frame 17. When the adjusting frame 17 moves to the preset limit position, the first limiting block 38 at one end of the first guide rod 16 contacts the side of the adjusting frame 17, preventing the adjusting frame 17 from continuing to move and avoiding the adjusting frame 17 from disengaging from the first guide rod 16 due to excessive movement. The beneficial effects of this embodiment are that the cooperation between the sliding hole and the first guide rod 16 improves the stability of the lateral movement of the adjustment frame 17 and reduces the occurrence of deviation or jamming; the first limit block 38 plays a limiting protection role to prevent the adjustment frame 17 from moving beyond its travel range and causing damage to the components.

[0037] In a further preferred embodiment of the present invention, the base plate 1 is provided with an assembly groove and a through hole, the assembly groove being adapted to the spring 26, and the through hole being adapted to the slide rod 25.

[0038] In this embodiment, the assembly groove provides positioning protection for the spring 26, preventing the spring 26 from becoming misaligned during compression or rebound, and ensuring the continuous operation of the positioning mechanism; the through hole provides stable guidance for the slide rod 25, making the lifting and lowering movement of the positioning block 28 smoother.

[0039] In a further preferred embodiment of the present invention, an annular heat insulation cover is fixed on the support seat 10. The annular heat insulation cover is arranged around the furnace body 40, and its inner wall is lined with fiber heat insulation modules. The heat insulation cover and the furnace body 40 are sealed by high-temperature resistant packing.

[0040] In this embodiment, the fiber insulation module can reduce the temperature loss of the molten aluminum inside the furnace body 40, helping to maintain the stability of the molten aluminum temperature; the high-temperature packing enhances the sealing between the insulation cover and the furnace body 40, reducing heat loss. The overall structure provides continuous insulation and protection for the furnace body 40, which helps to ensure the quality of the molten aluminum and provides favorable conditions for subsequent casting production.

[0041] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a braking mechanism is provided on the slide rod 25, the braking mechanism comprising: a fixing sleeve 32 fixedly sleeved on the slide rod 25; a connecting frame 33 symmetrically fixed on the fixing sleeve 32; an assembly plate 35 fixed on the connecting frame 33, a brake pad 36 fixed on the assembly plate 35, the brake pad 36 being adapted to the traveling wheel 3; a second guide rod 34 fixed on the base plate 1, the second guide rod 34 passing through the connecting frame 33; and a second limiting block 39 fixed on the second guide rod 34.

[0042] In this embodiment, after the base plate 1 reaches the furnace replacement point, when the slide bar 25 slides down, it drives the fixing sleeve 32 to descend synchronously, and the fixing sleeve 32 drives the connecting frame 33 to move down along the second guide rod 34; During the downward movement of the connecting frame 33, the mounting plate 35 and the brake pad 36 are driven to descend together, so that the brake pad 36 gradually comes into contact with the traveling wheel 3, forming a braking constraint on the traveling wheel 3. The braking mechanism works in conjunction with the positioning mechanism to further restrict the movement of the base plate 1 and improve the overall stability during the furnace changing process; the second guide rod 34 ensures that the connecting frame 33 rises and falls smoothly, and the second limit block 39 prevents the components from moving beyond their travel range; the brake pad 36 and the traveling wheel 3 fit together to form double protection, reducing the risk of displacement when the furnace body 40 is transferred and docked, and helping to reduce the probability of aluminum liquid leakage.

[0043] In summary, compared with related technologies, the basic transfer frame, consisting of base plate 1, traveling wheels 3, and platform plate 7, along with the first guide plate 8 and second guide plate 9 of the guiding mechanism, enables precise positioning of the furnace body 40. The traveling mechanism's first motor 5, speed control box 4, and shaft 2 drive the equipment to move smoothly. Simultaneously, the limiting mechanism's insert block 14 and groove block 11, in conjunction with the adjusting mechanism's adjusting frame 17 and first inclined groove 20, enhance the fixing effect of the bearing seat 10. The positioning mechanism's slide rod 25 and positioning block 28, along with the braking mechanism's brake pad 36, form double protection, while the annular insulation cover ensures stable aluminum liquid temperature. Through the coordinated operation of various mechanisms, the overall structure improves the stability and convenience of the furnace changing process, effectively reduces the risk of aluminum liquid leakage and splashing, and ensures production safety and continuity.

[0044] It is worth noting that during the operation of the furnace changing system, the central control system (using PLC machining control mode) achieves automated control of the furnace changing process, reducing manual intervention. As the core control unit of the furnace changing system, the central control system uses PLC machining control mode and is equipped with a Chinese touchscreen operation interface. It has three operating modes: automatic, semi-automatic, and manual, adaptable to the needs of different production scenarios. In automatic mode, the system can preset the parameters for the entire furnace changing process, including the moving speed of the traveling wheels 3, the triggering timing of the positioning mechanism, and the execution sequence of docking actions. This achieves fully automated operation from feeding, transferring, and positioning the furnace body 40 to docking, requiring no manual intervention throughout the entire process and significantly improving furnace changing efficiency.

[0045] The control system has a built-in storage function for 500 sets of process parameters, which can be preset to meet the production needs of castings of different specifications. These parameters can be directly called up when needed without repeated debugging. At the same time, the system has a real-time monitoring function, which can dynamically display the equipment operating status, including the position of the traveling mechanism, the locking status of the positioning mechanism, the braking status of the braking mechanism, and key parameters such as the temperature and pressure of the furnace body, so that operators can keep track of the equipment's operation in real time.

[0046] To ensure operational safety, the control system employs a three-tiered access control system: operator access, administrator access, and manufacturer access. Different access levels correspond to different operational scopes, preventing unauthorized personnel from modifying critical process parameters. Furthermore, the system is equipped with comprehensive alarm functions. When an equipment malfunction is detected (such as positioning block 28 not fully inserted into limit seat 27, brake pad 36 not properly engaged, or abnormal furnace body temperature 40), an audible and visual alarm will be immediately triggered, and the fault location and cause will be displayed on the touchscreen, alerting operators to address the issue promptly and prevent further escalation.
