Description

Technical Field

[0001] This utility model relates to the field of generator set technology, and in particular to a dual-purpose generator set for welding and power generation that is easy to adjust. Background Technology

[0002] In industrial production and maintenance operations, dual-purpose generator sets for both welding and power generation are widely used in construction sites, field operations, and other scenarios because they combine power generation and welding functions.

[0003] An existing adjustable dual-purpose welding and power generation generator set features a main spring vertically fixed to both sides of the center of the upper surface of a sliding plate. A support plate is horizontally fixed to the upper end of the main spring. Sub-plates are inclinedly arranged on both sides of the upper surface of the sliding plate, with one end of the sub-plate closest to the center of the sliding plate hinged to the upper surface of the sliding plate. The front port of the power connection frame facilitates the insertion of external equipment plugs. When welding clamps are needed, the U-shaped frame slides downwards along the slide rail, causing the U-shaped frame to push downwards along the top U-shaped frame. The top U-shaped frame presses against the outer end of the cover plate at the upper end of the power connection frame, causing the cover plate to first rotate upwards to a vertical position, opening the upper port of the power connection frame. Then, the top U-shaped frame continues to press downwards, causing the cover plate to slide down the slide rail until the conductive post on the top U-shaped frame inserts between the conductive clamps. Finally, the fixing posts on both sides of the U-shaped frame are inserted into the fixing sleeves, fixing the U-shaped frame and the conductive posts in place.

[0004] However, the rewind springs located at both ends of the winding column of this device always exert a winding force on the wire during use. This can easily reduce the service life of the wire due to prolonged pulling on it.

[0005] Therefore, it is necessary to provide a dual-purpose generator set for welding and power generation that is easy to adjust to solve the above-mentioned technical problems. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a dual-purpose generator set for welding and power generation that is easy to adjust, provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the cabinet. Figure 3 for Figure 2 The diagram shows another perspective of the structure. Figure 4 for Figure 3 The diagram shows a side cross-sectional view of the limiting frame. Figure 5 for Figure 2 The enlarged schematic diagram of part A is shown. A dual-purpose generator set for welding and power generation, which is easy to adjust, includes: a main body 1;

[0030] Placement frame 2, which is disposed on the side of the main body 1;

[0031] A rotating shaft 3 is rotatably connected to the inner side of the placement frame 2. A winding wheel 31 is fixedly installed on the outer side of the rotating shaft 3. A torsion spring 32 is fixedly installed on one end of each winding wheel 31. One end of the torsion spring 32 is fixedly installed on the inner side of the placement frame 2. A ratchet 33 is fixedly installed on one end of the rotating shaft 3.

[0032] A limiting frame 5 is fixedly installed on the side of the placement frame 2. A mounting bracket 56 is fixedly installed on the top of the inner side of the limiting frame 5. A sliding rod 52 is slidably connected to the top of the limiting frame 5. A handle 51 is fixedly installed on the top of the sliding rod 52. A limiting plate 54 is fixedly installed on the bottom of the sliding rod 52. A limiting rod 55 is fixedly installed on the bottom of the limiting plate 54. The bottom of the limiting rod 55 is engaged with the ratchet 33. A spring 53 is sleeved on the outer side of the sliding rod 52.

[0033] The outer side of the take-up reel 31 is wound with welding wire 4, and one end of the welding wire 4 is fixedly installed with welding clamp 41.

[0034] The bottom of the limiting plate 54 is located at the bottom of the inner side of the mounting bracket 56, and the limiting rod 55 is slidably connected to the inside of the bottom of the mounting bracket 56.

[0035] A power socket 22 is fixedly installed on the inner side of the placement frame 2, and a door 21 is rotatably connected to the side of the placement frame 2.

[0036] Body 1 employs high-frequency inverter technology, brushless AC synchronous generator technology, and permanent magnet generator technology. Through high-frequency inverter technology, the generated output is converted into the voltage and current required for welding, significantly reducing the size, weight, and losses of the welding machine, and improving the overall efficiency. Simultaneously, due to its high-frequency operation, it exhibits strong welding penetration, a deep molten pool, and features easy arc ignition, minimal spatter, stable current, and good weld formation, all of which contribute to improving the quality of welded products.

[0037] The brushless AC generator and welding dual-purpose machine uses a brushless AC synchronous generator generating winding, a welding winding, and a three-phase silicon rectifier module. The generator stator generating winding is embedded in the generator stator slot in a counterclockwise arrangement, and the welding winding is embedded in the generator stator slot. After being rectified by the three-phase silicon rectifier module, the welding winding outputs DC power. The positive terminal is the welding torch output, and the negative terminal is grounded output for welding.

[0038] By using a permanent magnet generator, the characteristic of the voltage of the permanent magnet generator dropping parabola under load can be utilized to achieve the constant current and voltage transformation curve requirements during welding. Compared with non-permanent magnet generators such as excitation motors, better welding results can be achieved.

[0039] It features easy arc ignition, minimal spatter, stable current, and good weld formation, which helps improve the quality of welded products. Compared with DC arc welding machines and brushed generator welding machines, it has higher efficiency, lower heat loss, greater energy saving, and no easily damaged parts. The permanent magnet motor can be a digital permanent magnet generator. Utilizing the small size, stable performance, and high power quality of the digital permanent magnet generator, the generator and welding dual-purpose machine of this invention has the advantages of being easy to carry, having a wider range of applications, and providing stable power at the generator end.

[0040] By installing a power socket 22 on the inner side of the placement frame 2, it is convenient for users to obtain power later.

[0041] The working principle of the easily adjustable dual-purpose welding and power generation generator set provided by this utility model is as follows:

[0042] When in use, the user opens the main body 1, opens the door 21, pulls the welding wire 4, the welding wire 4 drives the winding wheel 31 to rotate, the rotation of the winding wheel 31 synchronously drives the rotating shaft 3 and the ratchet 33 to rotate, and at the same time the torsion spring 32 bends to store force.

[0043] When the ratchet 33 rotates, it pushes the limit rod 55 to move upward. Due to the elasticity of the spring 53, when the ratchet 33 stops rotating, the spring 53 pushes the limit plate 54 and the limit rod 55 to move downward, so that the limit rod 55 engages with the ratchet 33, limiting the ratchet 33, and then limiting the winding wheel 31, so as to prevent the welding wire 4 from being continuously pulled and taut.

[0044] After use, the user lifts the handle 51, causing the slide bar 52 and the limiting plate 54 to move upward, so that the limiting bar 55 is disengaged from the ratchet 33. At this time, the torsion spring 32 releases its elastic potential energy, causing the rotating shaft 3 and the winding wheel 31 to rotate and wind up the welding wire 4. After winding is completed, the user releases the handle 51, and under the action of the spring 53, the limiting bar 55 is engaged with the ratchet 33 again, fixing the position of the winding wheel 31.

[0045] Compared with related technologies, the adjustable dual-purpose generator set for welding and power generation provided by this utility model has the following advantages:

[0046] The structure, consisting of a rotating shaft 3, a winding wheel 31, a torsion spring 32, a ratchet 33, a limiting frame 5, a sliding rod 52, a spring 53, a limiting plate 54, a limiting rod 55, and a mounting bracket 56, works together to lock the winding wheel 31 during use. This keeps the welding wire 4 at the required length by engaging the limiting rod 55 with the ratchet 33, preventing the torsion spring 32 from constantly applying winding force to the welding wire 4. This reduces wear caused by prolonged tension and effectively extends the service life of the welding wire 4.

[0047] Second Embodiment

[0048] Please refer to the following: Figure 6 Based on the first embodiment of this application, which provides an easily adjustable dual-purpose generator set for both welding and power generation, the second embodiment of this application proposes another easily adjustable dual-purpose generator set for both welding and power generation. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0049] Specifically, the second embodiment of this application provides an adjustable dual-purpose generator set for welding and power generation, wherein a base plate 6 is fixedly installed on the bottom of the main body 1, and casters 7 are fixedly installed on all four sides of the bottom of the base plate 6.

[0050] Threaded rings 8 are fixedly installed on the inside of the base plate 6 around its perimeter, and threaded rods 81 are threadedly connected to the inner side of the threaded rings 8.

[0051] A rotating handle 82 is fixedly installed on the top of the threaded rod 81, and a pad 82 is fixedly installed on the bottom of the threaded rod 81.

[0052] The working principle of the easily adjustable dual-purpose welding and power generation generator set provided by this utility model is as follows:

[0053] When in use, if the user needs to move the generator set, the casters 7 can be rolled on the ground to move the device. After moving it to the appropriate position, the user can turn the handle 83, which will cause the threaded rod 81 to be threaded onto the inner side of the threaded ring 8. This will cause the threaded rod 81 to move the pad 82 downwards and into contact with the ground, thus supporting the device and preventing it from moving.

[0054] Compared with related technologies, the adjustable dual-purpose generator set for welding and power generation provided by this utility model has the following advantages:

[0055] The base plate 6, casters 7, threaded rings 8, threaded rods 81, pads 82, and handles 83 work together to facilitate user movement of the device, increasing its mobility, and also to limit its movement, preventing displacement during operation.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
