[0002] As the core load-bearing component for ship berthing and marine engineering equipment mooring, the quality of the chain link welding directly determines the overall service safety and structural reliability. Flash butt welding is a key processing technology in anchor chain manufacturing to achieve chain link docking.

[0003] Existing anchor chain welding processing devices mostly adopt an electrode clamping and cylinder-assisted welding structure. After welding, the anchor chain is prone to getting stuck between the upper and lower conductive clamps and cannot be automatically detached and discharged. When discharging manually, tools such as crowbars and hand-operated hoists are needed to pry and drag the anchor chain out. Especially for some large anchor chains, it is impossible for a single person to complete the handling and discharge operation. Two or more operators must work together, which makes the operation labor-intensive, time-consuming and labor-intensive. Therefore, it is necessary to improve the above-mentioned problems.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By cooperating with the lifting assembly and the upper and lower conductive clamps, the welded anchor chain can be automatically ejected without the need for manual assistance with tools such as crowbars or hand-operated hoists, improving the convenience and efficiency of material discharge and enabling automatic material discharge. Furthermore, the cooperation between the sliding block, guide rod, and second electric push rod in the lifting assembly facilitates the adaptation to anchor chains of different specifications. Even large anchor chains can be stably ejected without the need for two or more operators, improving the versatility and ease of operation of the device. This allows for the adaptation to various anchor chain specifications and enables a single person to complete the material discharge operation. Ultimately, this solves the problem that existing anchor chain welding processing devices require manual assistance with tools for material discharge and multiple operators for large anchor chains, resulting in high labor intensity and time-consuming operations.

[0023] 2. By setting up an adaptive adjustment unit, the system utilizes a laser three-dimensional dimension detection module to automatically and non-contactly collect specification data such as the inner width of the chain links and the nominal diameter of the rod of the anchor chain. Multiple sets of data undergo preprocessing, including mean and standard deviation calculations and outlier removal, to ensure the accuracy and reliability of the specification data. Based on this, the system automatically calculates the target extension stroke or rotation angle of the first cylinder, second electric push rod, third electric push rod, and drive motor according to a parameter matching algorithm model pre-stored in the PLC, driving each actuator to complete adaptive adjustment. This technical solution eliminates the need for manual adjustments to equipment parameters based on the anchor chain specifications, achieving automatic and precise matching of clamping spacing, lifting position, and protective barrier. This significantly improves the device's versatility and adjustment efficiency for anchor chains of different specifications, avoiding problems such as unstable clamping or ejection offset caused by manual adjustment errors.

[0024] 3. By setting up an anomaly diagnosis unit, the system collects instantaneous current and weld temperature in real time during the welding process, calculates four key data points: welding current integral, welding heat integral, effective welding time, and effective holding time, and compares them with corresponding preset thresholds. When all four data points meet the standards, the system automatically triggers the lifting and unloading of the material, replacing the traditional method of manually observing and judging the welding timing. When different combinations of non-compliance occur, the system can accurately identify abnormal types such as incomplete welding, false fusion, and energy waste, and prohibits lifting and issues corresponding audible and visual alarms. This technical solution realizes automatic quantitative judgment and anomaly classification diagnosis of welding status, effectively avoiding welding quality defects or reduced work efficiency caused by human judgment errors, and improving the consistency of welding quality and process controllability.

A protective component for preventing sparks from splashing onto the operator is slidably installed on the end face of the machine base 1 away from the mounting base 2. The first cylinder 5 and the second cylinder 6 are SC series cylinders. The machine base 1 is made of Q235 cold-rolled steel plate, which has high structural strength and strong resistance to deformation, and is suitable for the load-bearing requirements of anchor chain processing. The mounting base 2 and the sliding mounting plate 4 are made of 45# steel, which has high hardness and good wear resistance, extending the service life of the device. The above structure constitutes the core framework of the device, realizing the basic functions of clamping and welding the anchor chain, providing stable support for subsequent welding operations, ensuring accurate anchor chain docking, and taking into account the convenience of operation, laying the foundation for subsequent automatic material discharge and safety protection.

[0034] Reference Figures 2 to 3As shown, the lifting assembly includes a sliding block 11 slidably disposed at the bottom of the embedded groove. A first electric actuator is fixedly connected to the top surface of the sliding block 11, and a ceramic plate 12 for abutting the bottom surface of the anchor chain is fixedly connected to the telescopic end of the first electric actuator. The first and second electric actuators are DT series electric actuators. The ceramic plate 12 is made of alumina ceramic material, which is resistant to high temperature and has good insulation, avoiding the risk of electric shock during the lifting process, ensuring operational safety, and also preventing the anchor chain surface from being scratched, ensuring the integrity of the anchor chain after welding. This structure can realize automatic lifting of the anchor chain after welding, without the need for...

[0035] Example 2: The technical solution is basically the same as that of Example 1, except that, as Figure 4 As shown, the protective assembly includes a slide groove on the outer wall of one end of the machine base 1. An inverted T-shaped groove is formed on the bottom surface of the slide groove. A movable block slides within the inverted T-shaped groove. An L-shaped plate is fixed to the top surface of the movable block. A telescopic groove is formed on the top surface of the L-shaped plate, and a lifting baffle 13 slides within the telescopic groove. The third electric actuator is a DT series electric actuator. The drive motor is an HG-AK0236 servo motor. The lifting baffle 13 is made of Q235 steel plate with a high-temperature resistant coating to enhance fire protection. The rack 14 is made of 40Cr material, with hardened teeth for wear resistance and high transmission accuracy. This structure effectively blocks sparks generated during welding, preventing sparks from flying and causing injury. The movable design of the L-shaped plate... The design is adapted to the protection requirements of different welding positions, improving operational safety. Two third electric actuators are symmetrically arranged on the bottom surface of the telescopic groove. The telescopic ends of the third electric actuators are fixedly connected to the bottom end of the lifting baffle 13. A rack 14 is fixedly connected to the horizontal surface of the L-shaped plate. A drive motor is embedded and fixedly connected in the middle of the top surface of the groove. The output shaft of the drive motor is fixedly connected to a gear that meshes with the rack 14. Movable grooves are opened on both sides of the inner wall of the groove, and both ends of the rack 14 extend into the movable grooves. The third electric actuators can precisely adjust the height of the lifting baffle 13 to adapt to the protection requirements of different welding scenarios. The meshing transmission between the gear and the rack 14 enables the smooth movement of the L-shaped plate, ensuring that the protective components can quickly switch to the working position, further improving the protective effect.

[0036] Reference Figure 1As shown, a control cabinet is fixed to one side of the machine 1. A control panel is located at the top of one end of the control cabinet, and multiple control buttons are located at the bottom of the control panel. The control cabinet is made of cold-rolled steel plate, which has good protective performance and can effectively protect the internal electrical components. The control cabinet can centrally install control components. The control panel and control buttons make it easy for operators to quickly adjust equipment parameters, achieve precise control of each component, reduce the difficulty of operation, improve work efficiency, and facilitate timely troubleshooting of equipment faults to ensure stable operation of the device.

[0037] Working principle: When using this invention, firstly, one end of the anchor chain is connected to the external traction and hoisting device. Then, the device is started through the control panel and control buttons on the control cabinet. According to the specifications of the anchor chain to be processed, the first cylinder 5 is adjusted to push the two sliding mounting plates 4 to slide along the slide guide rail 3 on the mounting base 2, so that the upper conductive clamp 8 and the lower conductive clamp 10 on the two sliding mounting plates 4 are adjusted to match the spacing of the anchor chain. Then, the two ends of the anchor chain to be welded are placed between the two sets of upper conductive clamp 8 and lower conductive clamp 10 respectively. The second cylinder 6 is started to push the upper electrode seat 7 to move downward, which drives the upper conductive clamp 8 to move downward, and cooperates with the lower conductive clamp 10 to clamp the two ends of the anchor chain, thereby achieving the positioning and fixing of the anchor chain.

[0038] At the same time, the protective components can be activated via the control panel. The drive motor drives the gear to rotate, and the gear meshes with the rack 14, causing the movable block and L-shaped plate to slide along the slide groove on the machine base 1. This moves the L-shaped plate to the front of the welding operation area. Then, the third electric push rod pushes the lifting baffle 13 to rise along the telescopic groove to form a protective barrier, preventing sparks from flying during welding from injuring the operators.

[0039] Once the anchor chain is clamped and fixed and the protective components are in place, the butt welding operation is initiated by connecting the power supply through the upper conductive clamp 8 and the lower conductive clamp 10. The high temperature generated by the current melts the joints at both ends of the anchor chain, allowing for fusion welding between the unfused links in the anchor chain. During the fusion welding process, the welding parameters are adjusted through the control panel of the control cabinet to ensure that the welding temperature and force meet the requirements, guaranteeing the welding quality and completing the butt welding of the anchor chain.

[0040] After welding is completed, the lifting assembly is activated. The second electric pusher pushes the sliding block 11 to move along the guide rod, causing the ceramic plate 12 to move below the anchor chain. Then, the first electric pusher pushes the ceramic plate 12 to rise, pushing the processed anchor chain out from between the upper and lower conductive clamps. The anchor chain is then lifted and removed by an external traction device. The device is now in use.
