Description

Technical Field

[0001] This utility model relates to the field of submerged arc welding machine technology, and in particular to a cantilever submerged arc welding machine. Background Technology

[0002] As a key piece of equipment in the modern industrial welding field, the cantilever submerged arc welding machine is widely used in industries such as machinery manufacturing, building steel structure, and shipbuilding due to its advantages such as high degree of automation and stable welding quality. In the welding process of large metal components, the cantilever submerged arc welding machine can efficiently complete the welding of long welds and thick plates through the flexible movement of the welding arm and the precise operation of the welding head, which greatly improves production efficiency and welding process level.

[0003] Existing cantilever submerged arc welding machines mainly consist of a trolley, welding arm, welding head, flux delivery and recovery system, and electrical control system. Their working principle involves the trolley moving the welding machine to the welding position, the welding arm delivering the welding head to the welding area, and the welding head's wire feeding mechanism feeding the welding wire into the arc zone. An arc is generated under the flux layer, causing the welding wire and base material to melt and form a weld. Simultaneously, the flux delivery and recovery system coordinates to spread and recover the flux, while the electrical control system regulates parameters such as welding current, voltage, and welding speed.

[0004] However, in practical applications, when the cantilever submerged arc welding machine is moving, or when the welding arm is extended over a long distance and bears a large load, it is prone to significant deformation and vibration due to the lack of an effective support structure. During the movement, factors such as the trolley's movement and uneven ground will further aggravate the swaying of the welding arm. This unstable state will cause the welding head to shift position during the welding process, making it difficult for the welding arc to be accurately aligned with the weld, which in turn leads to problems such as poor weld formation and reduced welding quality, seriously affecting welding efficiency and product quality. Therefore, a cantilever submerged arc welding machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a cantilever submerged arc welding machine, which aims to improve the problems of existing cantilever submerged arc welding machines, such as easy deformation and vibration of the welding arm due to the lack of an effective support structure during movement or when the welding arm is extended over a long distance and bears a large load, which in turn leads to displacement of the welding head, poor weld formation and reduced welding quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cantilever submerged arc welding machine includes a trolley, a welding arm fixedly connected to the top of the trolley, a control cabinet fixedly connected to the top of the trolley, and a support assembly provided on one side of the control cabinet.

[0008] The support assembly includes a connecting plate, one side of which is slidably connected to the outer wall of the trolley. A connecting frame one is fixedly connected to one side of the connecting plate, and a rotating frame one is rotatably connected inside the connecting frame one. A connecting frame two is fixedly connected to one side of the connecting plate, and a rotating frame two is rotatably connected inside the connecting frame two. A pneumatic push rod is rotatably connected to one side of the connecting plate, and a transmission rod is fixedly connected to the output end of the pneumatic push rod. The outer wall of the transmission rod is rotatably connected to both the rotating frame one and the rotating frame two. A support plate is fixedly connected to one end of the transmission rod, and an installation assembly is provided on one side of the connecting plate.

[0009] As a further description of the above technical solution:

[0010] The mounting assembly includes a fixing plate and a connecting shaft. The bottom of the fixing plate is fixedly connected to the upper surface of the trolley, and the outer wall of the connecting shaft is fixedly connected to the inside of the connecting plate.

[0011] As a further description of the above technical solution:

[0012] The connecting shaft is internally threaded with a screw rod, and a knob is fixedly connected to one end of the screw rod.

[0013] As a further description of the above technical solution:

[0014] A transmission column is fixedly connected to the other end of the screw, and an extrusion block is fixedly connected to one end of the transmission column.

[0015] As a further description of the above technical solution:

[0016] The fixing plate has a slot inside, and multiple locking balls are slidably connected inside the connecting shaft.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the extrusion block contacts the outer wall of the locking ball, and the locking ball engages with the locking groove.

[0019] As a further description of the above technical solution:

[0020] The knob is made of rubber, and the extrusion block is conical.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the pneumatic push rod output end drives the transmission rod forward, thereby causing the rotating frame one and rotating frame two to rotate synchronously inside the connecting frame one and connecting frame two. This causes the transmission rod to drive the support plate to move downward. The contact between the support plate and the ground forms additional support, thereby increasing the support force between the equipment and the ground. This solves the problem of welding arm deformation and welding head position displacement caused by insufficient support when the cantilever submerged arc welding machine is moved or under heavy load, and improves welding accuracy and stability.

[0023] 2. In this utility model, by rotating the knob, the screw moves inside the connecting shaft. The movement of the screw drives the extrusion block to press the locking ball, so that the locking ball is locked into the slot, thereby achieving the effect of quick installation and disassembly of the support component. This solves the problem of inconvenient installation and maintenance of the support component and improves the flexibility and maintenance efficiency of the equipment. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1-3 The present invention provides an embodiment of a cantilever submerged arc welding machine, including a trolley 1, a welding arm 2 fixedly connected to the top of the trolley 1 for supporting and adjusting the angle and position of the welding operation, a control cabinet 3 fixedly connected to the top of the trolley 1, the control cabinet 3 integrating electrical control components and operation interface for welding process, facilitating real-time monitoring and adjustment of the equipment by the operator, and a support component is provided on one side of the control cabinet 3 for additional support of the equipment;

[0033] The support assembly includes a connecting plate 4, one side of which is slidably connected to the outer wall of the trolley 1. The connecting plate 4 serves to provide stable support and connection for the installation assembly. A connecting frame 5 is fixedly connected to one side of the connecting plate 4. A rotating frame 6 is rotatably connected inside the connecting frame 5. The rotating frame 6 ensures the stability of the movement of the support plate 11. A connecting frame 8 is fixedly connected to one side of the connecting plate 4. A rotating frame 9 is rotatably connected inside the connecting frame 8. A pneumatic push rod 7 is rotatably connected to one side of the connecting plate 4. The pneumatic push rod 7 provides power to the support assembly, ensuring its rapid response. A transmission rod 10 is fixedly connected to the output end of the pneumatic push rod 7. The transmission rod 10 further transmits force, thereby driving the support plate 11 to contact the ground. The outer wall of the transmission rod 10 is rotatably connected to both the rotating frame 6 and the rotating frame 9. One end of the transmission rod 10 is fixedly connected to the support plate 11, which contacts the ground, thereby increasing the friction between the equipment and the ground. An installation assembly is provided on one side of the connecting plate 4 to facilitate quick installation of the support assembly by the user.

[0034] Specifically, when the cantilever submerged arc welding machine is moving, or when performing long-distance welding or welding large, heavy-duty workpieces, causing the welding arm 2 to extend excessively and bear a heavy load, it is prone to shaking and deformation, affecting welding accuracy and quality. The output end of the pneumatic push rod 7 pushes the transmission rod 10, causing it to rotate under the guidance of rotating frame 6 and rotating frame 9. Rotating frame 6 and rotating frame 9 are respectively installed inside connecting frame 5 and connecting frame 8. Therefore, when the transmission rod 10 rotates, rotating frame 6 and rotating frame 9 rotate synchronously, thereby driving the various components inside connecting frame 5 and connecting frame 8 to move synchronously. This movement allows the transmission rod 10 to move downwards, thereby driving the support plate 11 to contact the ground. The downward pressure of the support plate 11 increases the friction between the equipment and the ground, providing additional support force to the equipment, thus effectively improving the stability of the equipment and ensuring its smooth operation during use.

[0035] Reference Figures 1-3 The mounting assembly includes a fixing plate 12 and a connecting shaft 13. The bottom of the fixing plate 12 is fixedly connected to the upper surface of the trolley 1, and the outer wall of the connecting shaft 13 is fixedly connected to the inside of the connecting plate 4. The function of the fixing plate 12 and the connecting shaft 13 in the mounting assembly is to provide stable support and connection for the mounting assembly. A screw 14 is threadedly connected inside the connecting shaft 13, and a knob 15 is fixedly connected to one end of the screw 14. The function of the knob 15 is to facilitate the user to quickly drive the movement of the mounting assembly, providing convenient operation for the operator. 4. A transmission column 16 is fixedly connected to the other end. A pressing block 17 is fixed inside one end of the transmission column 16. The function of the pressing block 17 is to press the locking ball 19 so that the locking ball 19 can be locked into the slot 18, realizing the locking and unlocking function of the installation component. The fixing plate 12 has a slot 18 inside. Multiple locking balls 19 are slidably connected inside the connecting shaft 13. The outer wall of the pressing block 17 contacts the outer wall of the locking ball 19. The locking ball 19 fits into the slot 18. The knob 15 is made of rubber. The pressing block 17 is conical.

[0036] Specifically, when the equipment needs maintenance or support component installation, the operation becomes simple and efficient. The user first mates the connecting plate 4 with the fixing plate 12 to securely connect them. Then, the user rotates the knob 15. This action drives the screw 14 to move along the inside of the connecting shaft 13. The movement of the screw 14 drives the pressing block 17 to move synchronously. The movement of the pressing block 17 gradually squeezes and pushes the locking ball 19, causing the locking ball 19 to slide along the groove inside the connecting shaft 13 and finally lock into the slot 18. This not only achieves the positioning of the locking ball 19, but also effectively restricts the further movement of the locking ball 19, ensuring that it is firmly locked in the slot 18. This allows the user to complete the work quickly and safely when performing equipment maintenance and support component installation, greatly improving work efficiency.

[0037] Working Principle: When using this cantilever submerged arc welding machine, the pneumatic push rod 7 pushes the transmission rod 10, causing the transmission rod 10 to rotate inside the rotating frame 6 and rotating frame 9. This synchronously drives the rotating frame 6 and rotating frame 9 to rotate inside the connecting frame 5 and connecting frame 8, allowing the transmission rod 10 to move downwards. The movement of the transmission rod 10 drives the support plate 11 to contact the ground, providing additional support force for the equipment, increasing the friction between the equipment and the ground, and ensuring the stability of the equipment. This is especially important when maintenance or installation of the support components is required. First, the user attaches the connecting plate 4 to the fixing plate 12, and then rotates the knob 15. The rotation of the knob 15 will further move the screw 14 inside the connecting shaft 13. The movement of the screw 14 will drive the pressing block 17 to move synchronously. During the movement of the pressing block 17, it will gradually press the locking ball 19, causing the locking ball 19 to slide and lock into the slot 18 inside the connecting shaft 13. At the same time, it will restrict the movement of the locking ball 19, so that it is firmly locked into the slot 18, providing convenient maintenance and installation operations for the user.

[0038] 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.
