Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a voltage stabilization and protection device for high-frequency welded pipe welding power supply. Background Technology

[0002] Welding power supply voltage stabilization and protection devices are key components for ensuring welding quality and safe equipment operation. During the welding process, a stable power supply is crucial for ensuring precise control of welding parameters, which directly affects the quality of the weld and welding efficiency. For example, fluctuations in voltage or current may lead to poor weld formation, insufficient penetration, or welding defects such as porosity and slag inclusions, thereby affecting the integrity and strength of the welded structure. In addition, welding power supplies may face various emergencies during operation, such as grid voltage fluctuations, short circuits, or overloads. If these situations are not effectively controlled and protected, they may cause serious damage to the welding equipment or even lead to safety accidents.

[0003] Traditional welding power supply voltage stabilization and protection devices present many inconveniences in terms of installation and maintenance. Typically, these devices require the use of various complex tools and bolts for installation, and the installation and disassembly process involves cumbersome steps. This not only consumes a lot of time and manpower, but may also lead to untimely equipment maintenance. Due to the complexity of maintenance, the equipment cannot be repaired quickly when a fault occurs. This not only reduces the service life of the equipment, but may also affect the welding quality and lead to welding defects. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-frequency welded pipe welding power supply voltage stabilization and protection device.

[0005] This utility model is achieved using the following technical solution: a high-frequency welded pipe welding power supply voltage stabilization and protection device, including a mounting frame, an embedded groove on the surface of the mounting frame, an assembly block slidably connected inside the embedded groove, a locking rod fixedly connected to the lower surface of the assembly block, a protection device body fixedly connected to the surface of the assembly block, a connecting plate fixedly connected to the surface of the mounting frame, a crossbar fixedly connected to the surface of the connecting plate, positioning sleeves fixedly connected to both sides of the upper surface of the crossbar, slots on the surfaces of the locking rod and the positioning sleeves, and a positioning mechanism on the surface of the mounting frame; the positioning mechanism includes a guide groove, a sliding block slidably connected inside the guide groove, an extension block fixedly connected to the surface of the sliding block, a positioning rod fixedly connected to the surface of the extension block, a telescopic spring fixedly connected to the surface of the sliding block, and a pull rod fixedly connected to the surface of the sliding block.

[0006] Through the above technical solution, the assembly block is embedded in the sliding groove, effectively preventing horizontal shaking of the protection device body after installation; the positioning rod passes through the hole groove of the locking rod and the positioning sleeve, so that the locking rod is firmly connected to the positioning sleeve, improving the installation stability of the protection device body, and the quick disassembly and assembly design facilitates personnel to maintain and repair the protection device body, significantly improving work efficiency. The equipment model of the protection device body is WPS-3000, which is a common high-frequency welded pipe welding power supply voltage stabilization protection device, suitable for medium power welding applications, with automatic voltage stabilization function, which can maintain the stability of welding voltage when the mains voltage fluctuates.

[0007] As a further improvement to the above scheme, two guide grooves are provided, which are respectively opened on both sides of the upper surface of the cross frame.

[0008] As a further improvement to the above solution, the telescopic spring is fixedly connected to the inner wall of the guide groove.

[0009] As a further improvement to the above solution, the positioning rod is adapted to the slot.

[0010] The above technical solutions improve the stability and reliability of the locking mechanism, effectively preventing the protective device from loosening or falling off due to external forces or other factors during use.

[0011] As a further improvement to the above solution, the surface of the mounting bracket is provided with a protruding groove that matches the locking rod.

[0012] As a further improvement to the above solution, pre-set bolt grooves are provided on both sides of the connecting plate surface.

[0013] As a further improvement to the above solution, the locking rod is adapted to the positioning sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a pull rod to move a sliding block along a guide groove, thereby causing the positioning rod to disengage from or pass through the holes and slots of the locking rod and positioning sleeve. This achieves locking and unlocking of the protection device and the mounting bracket, making the installation and disassembly of the protection device extremely convenient and significantly saving operation time. Compared with traditional installation methods, this device does not require complicated tools and cumbersome steps. Simply pulling the pull rod allows for quick assembly and disassembly, significantly improving work efficiency. The convenience of quick assembly and disassembly avoids the problem of untimely equipment maintenance due to inconvenient assembly and disassembly, and extends the service life of the voltage stabilizing protection device.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] Please combine Figure 1-4 The high-frequency welded pipe welding power supply voltage stabilization and protection device of this embodiment includes a mounting frame 1. The surface of the mounting frame 1 is provided with an embedded sliding groove 2. An assembly block 3 is slidably connected inside the embedded sliding groove 2. A locking rod 4 is fixedly connected to the lower surface of the assembly block 3. A protection device body 5 is fixedly connected to the surface of the assembly block 3. A connecting plate 6 is fixedly connected to the surface of the mounting frame 1. A cross frame 7 is fixedly connected to the surface of the connecting plate 6. Positioning sleeves 8 are fixedly connected to both sides of the upper surface of the cross frame 7. Holes and slots 9 are provided on the surfaces of the locking rod 4 and the positioning sleeves 8. A positioning mechanism 10 is provided on the surface of the mounting frame 1.

[0019] The positioning mechanism 10 includes a guide groove 1001, a sliding block 1002 slidably connected inside the guide groove 1001, an extension block 1003 fixedly connected to the surface of the sliding block 1002, a positioning rod 1004 fixedly connected to the surface of the extension block 1003, a telescopic spring 1005 fixedly connected to the surface of the sliding block 1002, and a pull rod 1006 fixedly connected to the surface of the sliding block 1002. Personnel first insert the assembly block 3 and locking rod 4 from the surface of the protective device body 5 into the embedded groove 2 of the mounting bracket 1. Then, by pulling the pull rod 1006, the sliding block 1002 is moved along the guide groove 1001, causing the sliding block 1002 to retract along with the extension block 1003 and the positioning rod 1004. Simultaneously, the compression spring 1005 is compressed, causing the positioning rod 1004 to disengage from the positioning sleeve 8. When the assembly block 3 slides to the installation position, the locking rod 4 passes through the mounting bracket 1 and enters the lower positioning sleeve 8. At this time, the hole groove 9 on the surface of the mounting bracket 1 coincides with the hole groove 9 on the surface of the positioning sleeve 8. The operator slowly releases the pull rod 1006, and the compression spring 1005 resets, causing the positioning rod 1004 to extend, allowing it to pass through the locking rod 4 and the hole groove 9 on the surface of the positioning sleeve 8, thereby locking the locking rod 4 and the positioning sleeve 8. This completes the quick installation of the mounting bracket 1 and the protective device body 5. When disassembling, the pull rod 1006 is pulled again to disengage the positioning rod 1004 from the hole groove 9, and the protective device body 5 can be removed from the mounting bracket 1.

[0020] There are two guide grooves 1001, which are respectively opened on both sides of the upper surface of the cross frame 7.

[0021] The telescopic spring 1005 is fixedly connected to the inner wall of the guide groove 1001. When the sliding block 1002 is pulled, the telescopic spring 1005 is compressed and stores energy. After the pull rod 1006 is released, the telescopic spring 1005 releases energy, pushes the sliding block 1002 to move along the guide groove 1001, and drives the positioning rod 1004 to extend, so as to realize the automatic reset and locking functions.

[0022] The positioning rod 1004 is adapted to the slot 9, ensuring that the positioning rod 1004 can be accurately inserted into the slot 9 on the locking rod 4 and the positioning sleeve 8, so as to achieve a tight and stable locking connection and ensure that the protective device body 5 will not loosen after installation.

[0023] The surface of the mounting bracket 1 is provided with a protruding groove 11 that is compatible with the locking rod 4. When the assembly block 3 and the embedded slide 2 are installed in place, the locking rod 4 smoothly enters the positioning sleeve 8 through the protruding groove 11.

[0024] Both sides of the connecting plate 6 are provided with preset bolt grooves 12, which facilitates the connection and fixing of the connecting plate 6 to the surface of the external equipment by means of bolts, so as to achieve stable installation of the mounting frame 1 and the external equipment.

[0025] The locking lever 4 is compatible with the positioning sleeve 8.

[0026] The implementation principle of the high-frequency welded pipe welding power supply voltage stabilization protection device in this application embodiment is as follows: When installing the high-frequency welded pipe welding power supply voltage stabilization protection device, the personnel first align the assembly block 3 and locking rod 4 on the surface of the protection device body 5 with the embedded groove 2 of the mounting frame 1. Then, the personnel pull the sliding block 1002 through the pull rod 1006, causing it to move along the guide groove 1001. During the movement, the sliding block 1002 drives the extension block 1003 and the positioning rod 1004 to retract, while compressing the telescopic spring 1005, causing the positioning rod 1004 to disengage from the positioning sleeve 8. Then, the assembly block 3 is inserted into the embedded groove 2, allowing the assembly block 3 to slide within the embedded groove 2. When the assembly block 3 slides to the installation position, the locking rod 4 will penetrate the mounting frame 1 and enter the interior of the lower positioning sleeve 8. At this time, the hole groove 9 on the surface of the mounting frame 1 coincides with the hole groove 9 on the surface of the positioning sleeve 8. Then, when the personnel slowly release the pulling force on the pull rod 1006, the telescopic spring... Spring 1005 automatically resets under the action of its elastic potential energy, pushing sliding block 1002 to move in the opposite direction along guide groove 1001, thereby driving positioning rod 1004 to extend, so that it accurately passes through the hole groove 9 on the surface of locking rod 4 and positioning sleeve 8, thereby achieving a tight and stable lock between locking rod 4 and positioning sleeve 8, completing the quick installation of mounting bracket 1 and protective device body 5. When disassembling protective device body 5 for maintenance and repair, personnel pull rod 1006 again, causing positioning rod 1004 to disengage from the hole groove 9 on the surface of locking rod 4 and positioning sleeve 8. At this time, the locking state between locking rod 4 and positioning sleeve 8 is released, and personnel can easily remove assembly block 3 and locking rod 4 from the inside of embedded groove 2 on the surface of protective device body 5, realizing the quick disassembly and separation of mounting bracket 1 and protective device body 5. The whole operation process is simple and quick, which facilitates personnel to maintain and repair protective device body 5, effectively improving work efficiency.

[0027] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
