Description

Technical Field

[0001] This utility model relates to the electrolytic aluminum industry and the field of automated aluminum ingot production lines, and in particular to an aluminum ingot clamping mechanism that uses a single power source to achieve clamping and lifting. Background Technology

[0002] With the development of the global economy and the continuous growth in demand for aluminum from various industries, the electrolytic aluminum industry is expanding in scale, and the requirements for production efficiency, quality stability and safe production are also increasing. In the traditional electrolytic aluminum production process, after aluminum ingots are produced, they need to be transported by conveyor belt and then handled manually or by simple machinery for subsequent processing such as handling and stacking. This production mode is inefficient, costly, and carries significant safety risks. Therefore, in order to enhance industry competitiveness and meet the ever-growing market demand, the electrolytic aluminum industry is gradually transforming towards automated production, and automated aluminum ingot production lines have emerged.

[0003] Existing aluminum ingot clamping mechanisms mostly adopt a dual-power source design, which drives the clamping and lifting actions separately. This not only results in a complex structure and a large number of parts, but also requires a complex control system to coordinate the synchronization of the two power sources. It is prone to asynchronous actions due to signal delays or power output deviations, leading to unstable aluminum ingot clamping or lifting jams, which affects production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an aluminum ingot clamping mechanism that uses a single power source to achieve clamping and lifting, aiming to improve the problems of complex structure, asynchronous operation, and high energy consumption of traditional dual-power source mechanisms.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum ingot clamping mechanism using a single power source for clamping and lifting, comprising a central crossbeam, clamping components symmetrically mounted on one side of the central crossbeam, a connecting component mounted on one side of the clamping component, a top component mounted on one side of the connecting component, a motor mounted on one side of the top of the top component, a drive shaft fixedly connected to the output end of the motor, vertical bearings with mounting seats symmetrically mounted on the top of the top component, square bearings with mounting seats symmetrically mounted on the inner wall of the top component, a driven shaft rotatably connected to one end of the square bearings with mounting seats, an installation shaft mounted on one end of the central crossbeam, a drive sprocket mounted on the outer wall of the drive shaft, a first driven sprocket mounted on one end of the installation shaft, a second driven sprocket mounted on the outer wall of the driven shaft, a first pin mounted inside one end of the connecting component, a second pin mounted inside the other end of the connecting component, and a chain mounted on the outer wall of the drive sprocket.

[0006] By adopting the above technical solution, the motor serves as the sole power source, driving the chain through the drive shaft and drive sprocket. This synchronously drives the first and second driven sprockets to link with the intermediate crossbeam. The intermediate crossbeam, connecting rod, clamping arm, and top frame form a four-bar linkage structure. When the crossbeam rises and falls, it naturally drives the clamping arm to open and close: when the crossbeam rises, the clamping arm retracts to hold the aluminum ingot, and the lifting is completed as it continues to rise; when the crossbeam falls, the clamping arm first lowers the aluminum ingot and then opens to complete the placement. Compared with the complex coordination and control required by multiple power sources, the control system of a single power source is easier to design, debug, and maintain. This reduces system complexity and failure probability, improves equipment reliability, and is also convenient for operators to master. It solves the problems of complex structure, asynchronous operation, and high energy consumption of traditional dual-power source mechanisms.

[0007] Preferably, the top component includes a top frame, with a first lifting point fixedly connected to one side of the middle portion of the top frame and a second lifting point fixedly connected to the other side of the middle portion of the top frame.

[0008] Preferably, a support plate is fixedly connected to one side of the top frame, and the motor is mounted on the top of the support plate.

[0009] Preferably, a first mounting plate is fixedly connected to the top of the top frame, and the vertical bearing with seat is mounted on the top of the first mounting plate.

[0010] Preferably, a second mounting plate is symmetrically fixedly connected inside the top frame, and the square bearing with seat is mounted on one side of the second mounting plate.

[0011] Preferably, the connecting assembly includes a connecting rod, one end of which has a second connecting hole and the other end of which has a connecting groove.

[0012] Preferably, the clamping assembly includes a clamping arm, one end of which has a third connecting hole and the other end of which has a fourth connecting hole.

[0013] Preferably, one end of the first pin is installed inside the second connecting hole and the top frame.

[0014] Preferably, one end of one of the second pins is installed inside the connecting groove and the third connecting hole, and one end of the other second pin is installed inside the first connecting hole and the fourth connecting hole.

[0015] Preferably, one side of the chain is sequentially arranged on one side of the first lifting point, the first driven sprocket, the driving sprocket, the second driven sprocket, and the second lifting point.

[0016] This utility model has the following beneficial effects: 1. In this utility model, the motor serves as the sole power source, driving the chain via the drive shaft and drive sprocket. This drives the first and second driven sprockets in conjunction with the intermediate crossbeam. The intermediate crossbeam, connecting rod, clamping arm, and top frame form a four-bar linkage structure. When the crossbeam rises and falls, it naturally causes the clamping arm to open and close: when the crossbeam rises, the clamping arm retracts to hold the aluminum ingot, and the lifting is completed as it continues to rise; when the crossbeam falls, the clamping arm first lowers the aluminum ingot and then opens to complete the placement. Compared to the complex coordination and control required by multiple power sources, the control system of a single power source is easier to design, debug, and maintain. This reduces system complexity and failure probability, improves equipment reliability, and is also convenient for operators to master. It solves the problems of complex structure, asynchronous operation, and high energy consumption of traditional dual-power-source mechanisms.

[0017] 2. In this utility model, the single power source design can significantly reduce enterprise costs. On the one hand, the reduction in the number of power sources and related components directly reduces equipment procurement expenditures. On the other hand, the simplification of components greatly reduces maintenance work. For example, the frequency of power equipment inspection, lubrication, and parts replacement is reduced, which not only reduces the workload of maintenance personnel but also shortens working hours, resulting in significant long-term cost savings. At the same time, this design can also improve energy utilization efficiency. A single power source can uniformly allocate energy according to actual load requirements, avoiding the energy waste commonly seen when multiple power sources operate separately. Taking the aluminum ingot clamping and lifting scenario as an example, the power source can automatically adjust its output power according to changes in the total load, allowing energy to be fully utilized. This truly meets the current development requirements for energy conservation and emission reduction, providing dual assistance to enterprises in achieving cost reduction and efficiency improvement and green production.

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Reference Figure 1 - Figure 14 This utility model provides an embodiment of an aluminum ingot clamping mechanism that uses a single power source to clamp and lift. It includes a central crossbeam 2, with clamping components symmetrically mounted on one side of the central crossbeam 2. A connecting component is mounted on one side of the clamping components, and a top component is mounted on one side of the connecting component. A motor 5 is mounted on the top side of the top component, and a drive shaft 10 is fixedly connected to the output end of the motor 5. Vertical bearings 12 are symmetrically mounted on the top of the top component, and square bearings 13 are symmetrically mounted on the inner wall of the top component. One end of the square bearing 13 is rotatably connected to a driven shaft 11. A mounting shaft 201 is mounted on one end of the central crossbeam 2. A drive sprocket 6 is mounted on the outer wall of the drive shaft 10. A first driven sprocket 7 is mounted on one end of the mounting shaft 201, and a second driven sprocket 8 is mounted on the outer wall of the driven shaft 11. A first pin 14 is installed inside one end of the connecting component, and a second pin 15 is installed inside the other end of the connecting component. A chain 9 is mounted on the outer wall of the drive sprocket 6.

[0032] Specifically, the intermediate crossbeam 2 serves as the mounting base for the clamping assembly, driving the first driven sprocket 7 to move synchronously via the mounting shaft 201. The clamping assembly directly clamps the aluminum ingot, while the connecting assembly connects the top assembly and the clamping assembly, achieving a rotatable connection through pins, providing space for the clamping action. The motor 5, as the sole power source, drives the drive shaft 10 to rotate the drive sprocket 6. The vertical bearing 12 and the square bearing 13 provide stable support for the drive shaft 10 and the driven shaft 11, respectively, ensuring smooth sprocket rotation. The first driven sprocket 7, the second driven sprocket 8, and the drive sprocket 6 are transmitted to the motor 5 synchronously via the chain 9, transmitting power from the motor 5 to the clamping and lifting actions. The first pin 14 securely connects the assembly and the top assembly, while the second pin 15 connects the assembly and the clamping assembly, and the intermediate crossbeam 2 and the clamping assembly, respectively. The opening and closing action of the clamping assembly is achieved through the rotational characteristics of the pins. The single power source design simplifies the structure, reduces energy consumption, and ensures synchronous action.

[0033] Reference Figure 1 , Figure 2 , Figure 5The top assembly includes a top frame 1, a first suspension point 101 fixedly connected to one side of the middle of the top frame 1, a second suspension point 102 fixedly connected to the other side of the middle of the top frame 1, a support plate 103 fixedly connected to one side of the top frame 1, a motor 5 mounted on the top of the support plate 103, a first mounting plate 104 fixedly connected to the top of the top frame 1, a vertical bearing with a seat 12 mounted on the top of the first mounting plate 104, a second mounting plate 105 symmetrically fixedly connected inside the top frame 1, and a square bearing with a seat 13 mounted on one side of the second mounting plate 105.

[0034] Specifically, the top frame 1 is the top support skeleton of the entire mechanism. The first suspension point 101 and the second suspension point 102 serve as suspension points for the chain 9. On the one hand, they provide a fulcrum for the chain 9 to ensure a closed transmission path. On the other hand, the support plate 103 provides a stable mounting platform for the motor 5 to ensure that the motor 5 does not shake during operation. The first mounting plate 104 and the second mounting plate 105 provide mounting positions for the vertical bearing 12 and the square bearing 13, respectively. Through the fixing effect of the mounting plates, the concentricity of the bearing and the shaft is ensured, reducing friction and noise during transmission and improving power transmission efficiency.

[0035] Reference Figure 1 , Figure 2 , Figure 7 , Figure 14 The connecting assembly includes a connecting rod 3, one end of which has a second connecting hole 301 and the other end of which has a connecting groove 302. The clamping assembly includes a clamping arm 4, one end of which has a third connecting hole 401 and the other end of which has a fourth connecting hole 402. One end of the first pin 14 is installed inside the second connecting hole 301 and the top frame 1. One end of one second pin 15 is installed inside the connecting groove 302 and the third connecting hole 401, and one end of the other second pin 15 is installed inside the first connecting hole 202 and the fourth connecting hole 402. One side of the chain 9 is sequentially arranged on one side of the first lifting point 101, the first driven sprocket 7, the driving sprocket 6, the second driven sprocket 8, and the second lifting point 102.

[0036] Specifically, the connecting rod 3, as the core of the connecting component, cooperates with the first pin 14 through the second connecting hole 301 to achieve a rotatable connection with the top frame 1; the connecting groove 302 reserves a space for movement and cooperates with the second pin 15 to connect with the third connecting hole 401 of the clamping arm 4, providing sufficient stroke for the opening and closing of the clamping arm 4; the fourth connecting hole 402 of the clamping arm 4 is connected with the first connecting hole 202 of the intermediate crossbeam 2 through the second pin 15, forming a four-link structure of the top frame 1, connecting rod 3, clamping arm 4, and intermediate crossbeam 2, ensuring stable clamping action; the chain 9 is sequentially wound around the first lifting point 101, the first driven sprocket 7, the driving sprocket 6, the second driven sprocket 8, and the second lifting point 102 to form a closed transmission chain. When the motor 5 drives the driving sprocket 6 to rotate, the chain 9 drives the first driven sprocket 7 and the second driven sprocket 8 to rotate synchronously, thereby linking the intermediate crossbeam 2 and the clamping component to achieve coordinated clamping and lifting actions under single power drive.

[0037] Working Principle: When the aluminum ingot clamping mechanism, which uses a single power source to clamp and lift, is working, it first enters the clamping-lifting process: After the aluminum ingot conveying device delivers the packaged aluminum ingot directly below the clamping assembly, the motor 5 is started. The output end of the motor 5 drives the drive shaft 10 and the drive sprocket 6 to rotate, which in turn drives the first driven sprocket 7 and the second driven sprocket 8 to rotate synchronously through the chain 9, thereby driving the middle crossbeam 2 to move upward. As the distance between the middle crossbeam 2 and the top frame 1 gradually shortens, the clamping arms 4 on both sides retract inward around the second pin 15 through the transmission drive of the connecting rod 3, until the inner wall of the clamping arm 4 is tightly attached to the outer wall of the aluminum ingot, firmly clamping the aluminum ingot. As the motor 5 continues to run, because the aluminum ingot forms a rigid constraint on the clamping arm 4, the clamping arm 4 can no longer retract inward. At this time, the second pin 15 connected to the clamping arm 4 can only slide upward along the connecting groove 302 of the connecting rod 3, thereby driving the clamping arm 4 and the clamped aluminum ingot to lift upward synchronously, gradually disengaging from the aluminum ingot conveying device, completing the clamping-lifting process.

[0038] The process then proceeds to the lowering and placement phase: After the clamping mechanism moves the aluminum ingot to the designated storage location, the motor 5 rotates in the reverse direction, driving the first driven sprocket 7 and the second driven sprocket 8 in the reverse direction via the chain 9, causing the middle crossbeam 2 to move downwards. Since the clamping arm 4 is holding the aluminum ingot, under the combined action of the mechanism's own weight and the weight of the aluminum ingot, the second pin 15, which passes through the connecting groove 302, slides downwards along the groove, driving the clamping arm 4 and the aluminum ingot to descend synchronously until the aluminum ingot is close to the storage yard ground. When the second pin 15 slides to the bottom limit position of the connecting groove 302, the motor 5 continues to rotate in the reverse direction, and through the transmission drive of the connecting rod 3, the clamping arms 4 on both sides slowly extend outwards around the second pin 15, placing the aluminum ingot smoothly at the designated location in the storage yard, completing the lowering-placement process.

[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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
