Abstract
Description
Technical Field
[0001] This utility model relates to an automatic welding specimen clamping device, specifically a multi-functional anti-fall fully automatic welding training workstation frame, which is suitable for welding training of large-diameter pipelines and equipment anti-fall protection. Background Technology
[0002] With the increasingly widespread application of automatic welding technology in industrial production, its efficient, stable, and high-quality welding results have made it a mainstream choice in many fields, especially in welding scenarios such as large pipelines and steel structures. Many welding training institutions have also followed this trend and launched automatic welding training programs to cultivate professional automatic welding personnel who can meet market demands.
[0003] However, existing welding workstations have many problems in automated welding training, making it difficult to meet the needs of actual teaching and assessment. Firstly, automated welding is often used in scenarios involving welding pipes with large diameters and thick walls. These welding tasks place extremely high demands on the clamping methods and support capabilities of the workstations. For example, large-diameter pipes require stable support during welding to prevent displacement due to gravity or vibrations during the welding process, which would affect welding quality and accuracy. Existing conventional workstations are mostly designed for manual welding, with limited clamping range and support strength, making them unsuitable for welding large-diameter pipes.
[0004] Secondly, existing welding workstations lack effective fall protection measures. Automatic welding machines are typically expensive and require precise operation and stable anchoring during welding. During training, due to trainees' lack of experience or accidental collisions with the equipment, there is a risk of the automatic welding machine falling from a height. A fall would not only damage the equipment and cause economic losses but could also endanger the personal safety of trainees. However, most welding workstations are currently not equipped with dedicated fall protection devices, posing a significant safety hazard to welding training.
[0005] Furthermore, existing welding workstations are functionally limited and cannot meet the training needs of various welding positions. For example, in pipe welding, common welding positions include 1G (flat welding), 5G (vertical welding), and 6G (overhead welding). Different welding positions have different requirements for the support and clamping angles of the workpiece, but existing workstations can usually only meet the needs of one or a few welding positions, and cannot be flexibly adjusted to adapt to training in multiple welding positions. This not only limits the diversity and completeness of training content, but also increases the cost and complexity of equipment configuration for training institutions. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a multi-functional anti-fall fully automatic welding training workstation frame, which uses bolts to fasten the test pieces and uses retaining rings and bearings to achieve the anti-fall function, and is suitable for training in various welding positions.
[0007] The technical solution adopted by this utility model to solve the technical problem is as follows:
[0008] A multifunctional, fall-prevention, fully automatic welding training workstation includes a base plate, supporting square steel, horizontal support arms, 45° inclined support arms, and fall-prevention extension components. The horizontal support arms and 45° inclined support arms are respectively disposed on both sides of the supporting square steel. The supporting square steel is vertically welded to the base plate. The horizontal support arms are welded to the top of the supporting square steel, and the 45° inclined support arms are welded to the middle of the supporting square steel. The fall-prevention extension components are disposed on the top of the 45° inclined support arms by interference fit.
[0009] Preferably, the base plate is evenly provided with four bolt holes for fixing to the ground; the horizontal support arm and the supporting square steel are distributed in an inverted "L" shape, and the horizontal support arm is provided with a horizontal clamp and a first fastening bolt; the 45° inclined support arm is at a 45° angle to the supporting square steel, and the 45° inclined support arm is provided with a 45° inclined clamp and a second fastening bolt; the fall protection extension assembly includes a bearing and a retaining ring welded to the outer ring of the bearing; a remote control fixing structure is welded in the middle of the supporting square steel, opposite in direction to the 45° inclined support arm, and located on both sides of the supporting square steel; the remote control fixing structure and the horizontal support arm are located on the same side of the supporting square steel.
[0010] Preferably, the horizontal clamp on the horizontal support arm and the 45° inclined clamp on the 45° inclined support arm are both welded from thick perforated plates, and the specimen is fastened by the first fastening bolt and the second fastening bolt, respectively.
[0011] Preferably, the retaining ring of the fall arrestor extension assembly is connected to the 45° inclined support arm via a bearing, and can rotate 360° along the central axis of the support arm.
[0012] Preferably, the outer surface of the remote control fixing structure is covered with a soft protective layer.
[0013] Preferably, the base plate, horizontal support arm, 45° inclined support arm and supporting square steel are all fixed by welding.
[0014] The positive and beneficial effects of this utility model are as follows:
[0015] 1. It can be used for training in multiple welding positions, achieving "one machine for multiple uses" and significantly saving training costs:
[0016] In traditional welding training, different welding positions (such as 1G, 5G, 6G, etc.) typically require different workstations, which not only increases the cost of equipment procurement and maintenance but also leads to low utilization of training space. This invention addresses this by designing a clamping system with both horizontal and 45° angles, flexibly adapting to the training needs of various welding positions. For example, during 1G (flat welding) training, a horizontal support arm can be used for workpiece support and clamping; while during 6G (overhead welding) training, the system can switch to a 45° support arm. This design allows a single workstation to meet the training needs of multiple welding positions, eliminating the need for frequent workstation changes, significantly improving equipment utilization, reducing the number of equipment purchases, and thus substantially lowering training costs.
[0017] 2. Adopt fall protection mechanisms to ensure the safety of trainees and equipment:
[0018] Automatic welding machines are expensive, and during welding training, they are prone to falling due to improper operation or accidental collisions. This can not only damage the equipment but also endanger the safety of trainees. This invention addresses this issue by installing a retaining ring welded to a bearing at the top of the support arm at a 45° angle, and securing the automatic welding machine to the retaining ring with a steel cable. This effectively prevents accidental falls of the automatic welding machine during training. The design of the retaining ring and bearing also allows for free rotation during welding, preventing entanglement of the fall arrest rope and further improving ease of use and safety. This fall arrest mechanism not only protects the expensive automatic welding machine from damage but also provides a safer working environment for trainees, reducing safety hazards during training and improving the overall quality and safety of the training.
[0019] 3. Modular design allows for quick expansion and dismantling, saving space:
[0020] This invention adopts a modular design concept, where each component (such as the support arm, clamping mechanism, and fall protection extension component) can be quickly assembled and disassembled through simple splicing and disassembly. This design not only facilitates the transportation and storage of the equipment but also allows for flexible adjustment of the workstation rack configuration according to actual training needs. For example, when the functionality of the workstation rack needs to be expanded, the fall protection extension component can be quickly installed; when not needed, it can be removed to restore the basic function of the workstation rack.
[0021] The modular design also allows the workstation racks to be easily disassembled and compactly stored when not in use, significantly saving space. This is especially important for welding training institutions, as they typically need to configure various training devices within a limited space. Through the modular design of this invention, the workstation racks can be disassembled and stored in a smaller space when not in use, thereby improving the utilization rate of the training area and freeing up more space for other equipment and training activities.
[0022] 4. Robust and stable structure, suitable for various welding scenarios:
[0023] This utility model's workstation frame is welded from robust steel, possessing high structural strength and stability. Its support columns and clamping mechanism are meticulously designed to withstand the weight of large-diameter, thick-walled pipes and various forces during the welding process. This robust and stable structural design ensures the reliability and durability of the workstation frame in various welding scenarios, providing stable support for both the workpiece and welding equipment, whether for flat, vertical, or overhead welding. Furthermore, the clamping mechanism is achieved through welding of perforated, thick-plate material, resulting in a sturdy structure that can accommodate workpieces of different sizes and shapes, further enhancing the workstation frame's versatility and applicability.
[0024] 5. Human-centered design enhances the training experience:
[0025] The remote control fixing structure of this invention features a protective layer made of soft material on its outer surface, effectively preventing mechanical damage to the remote control during storage. This user-friendly design not only protects this important device but also provides trainers with a more convenient operating experience. During training, trainees can securely fix the remote control to the small iron stand without worrying about storage, allowing them to focus more on the welding operation. 。
[0026] 6. Optimized layout and design to enhance welding training performance:
[0027] This invention features a simple structure and easy operation, enabling trainees to quickly become familiar with equipment operation and improving training efficiency. It not only addresses the shortcomings of existing workstation frames in terms of clamping methods, support capacity, fall prevention measures, and functional versatility, but also significantly enhances the safety, efficiency, and economy of welding training through its unique design and functions. It provides welding training institutions and trainees with an ideal automatic welding training device, yielding remarkable results. Attached Figure Description
