Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding machine mechanism for steel structure power tower components. Background Technology

[0002] Power transmission towers are the core load-bearing structures of high-voltage, ultra-high-voltage, and extra-high-voltage transmission lines. They are exposed to the outdoors for a long time and are subjected to complex conditions such as wind load, icing, earthquakes, and temperature differences. Their structural safety and welding quality directly determine the reliability and service life of the power grid. When processing tower components, angle steel needs to be welded, so a steel structure power transmission tower component welding machine mechanism is used. To this end, patent CN119952373B discloses a follow-up power tower welding device, including a base, side connecting plates fixedly connected to the front and rear ends of the base, a fixed support seat fixedly connected to the upper surface of the base, a drive mechanism fixedly connected to the side of the base, a movable seat slidably connected to the top of the drive mechanism, and a welder hinged to the lower surface of the movable seat. In this invention, the movable seat can quickly drive the welder to a specific position, improving welding efficiency. During welding, the tower component is placed on the fixed support seat to prevent the component from rolling, thus improving welding stability. The end of the positioning claw away from the side connecting plate contacts the tower component, thereby clamping the tower component and further improving welding stability. The end of the positioning claw near the side connecting plate is close to the annular fixed frame and pushes the sliding shaft to reset, thereby quickly releasing the tower component and making the operation more convenient. The aforementioned power tower welding device is only suitable for welding pipes. When the power tower is made of angle steel, the angle steel needs to be spliced ​​and the gaps between the angle steel need to be welded. During the welding of angle steel, the angle steel will expand due to local heating. The existing rigid clamping device restricts the expansion of the angle steel, which can easily lead to cracks in the weld and affect the service life of the power tower. At the same time, the existing clamps lack self-locking. Vibration during the welding process can easily cause the clamps to loosen, affecting the welding quality. Summary of the Invention

[0003] The purpose of this invention is to provide a welding machine mechanism for steel structure power tower components, which solves the defects of existing steel structure power tower component welding machine mechanisms, such as rigid clamping restricting the thermal expansion of angle steel and lack of self-locking.

The top of each movable seat is fixed with a clamping structure. The clamping structure includes a support base fixed to the top of the movable seat. A slide rail is fixed to the top of the support base. A fixing block is fixed to the top of one side of the support base. A pressure handle is hinged to the bottom of the other side of the support base. Slider blocks are provided on both sides of the top of the slide rail. A fixing plate is fixed to one side of the top of each slider. An internal cavity is opened at the top of the support base. A guide groove is opened at the middle position of the bottom end of the internal cavity of the support base. A connecting groove is opened on both sides of the guide groove of the support base. A pull rod is provided at the top of the guide groove. A snap-fit ​​groove is evenly opened on the side of the pull rod near the fixing block. A pressure rod is fixed to the bottom of the pull rod near the pressure handle. A hinge rod is hinged to both sides of the top of the pull rod. A spring is provided at the bottom of the guide groove.

[0005] Preferably, the bottom of the movable groove inside the fixed seat is evenly provided with chip removal grooves, the fixed seat is threaded with a locking handle on the side away from the welding machine, and guide rods pass through both sides inside the movable seat.

[0006] Preferably, both ends of the guide rod are fixedly connected to the inner sidewall of the fixed seat by bolts, the movable seat and the guide rod are slidably connected, and one end of the locking handle extends into the interior of the movable groove and abuts against one end of the movable seat.

[0007] Preferably, the bottom end of the fixed block is hinged to a swing seat, and a snap-fit ​​block is fixed to the bottom end of the swing seat near the support seat.

[0008] Preferably, the main view section of the swing seat is conical, the end of the locking block away from the swing seat extends through the connecting groove into the interior of the locking groove, the end of the locking groove near the pull rod is provided with a chamfer, and the locking block and the pull rod form a locking structure through the locking groove.

[0009] Preferably, the slide rail has a reserved groove inside, limit seats are fixedly installed on both sides of the bottom end of the slider, and a connecting seat is fixed on one side of the bottom end of the slider.

[0010] Preferably, the main view of the limiting seat is Z-shaped, the slider and the slide rail form a sliding structure through the limiting seat, and the connecting seat extends through the reserved groove into the interior cavity and is hinged to one end of the hinge rod.

[0011] Preferably, a mounting base is fixedly installed on one side of the fixed plate, and a movable plate is provided inside the mounting base. A first spring and a second spring are respectively provided on the side of the movable plate near the fixed plate. Engaging grooves are staggered on both sides of the first spring and the second spring. A clamping plate is fixed on the movable plate near the mounting base.

[0012] Preferably, the first and second springs are arc-shaped, and the two sides of the first and second springs engage with each other through a meshing groove to form a telescopic structure. One end of the clamping plate passes through the mounting base and is slidably connected to the mounting base.

[0013] Preferably, the top end of the pull rod extends into the interior of the built-in cavity, the bottom end of the pull rod abuts against the top end of the spring, the main view section of the snap-fit ​​groove is triangular, one end of the pressure rod extends through the connecting groove to the outside of the pressure handle, and the pressure rod is located at the bottom end of the pressure handle.

[0014] The welding machine mechanism for steel structure power tower components provided by this invention has the following advantages: By setting up a clamping structure, the angle steel is placed between the clamping plates at the top of the slide rail. When the fixed plate drives the clamping plate to clamp and fix the angle steel, the first and second spring pieces deform under the squeezing action of the movable plate and the fixed plate. Under the elastic force of the first and second spring pieces, the clamping plate clamps the angle steel tightly. At the same time, during welding, the angle steel is allowed to expand slightly, reducing restraint stress, avoiding cracks in the weld, and extending the service life of the power tower. Furthermore, by rotating the locking handle, one end of the locking handle comes into contact with one end of a set of movable seats, thereby fixing the set of movable seats to the guide rod. When the angle steel expands due to heat, under the sliding connection between the movable seats and the guide rod, the unfixed movable seats can slide inside the movable groove, increasing the distance between adjacent movable seats, preventing slight bending of the angle steel when it expands due to heat, reducing restraint stress, preventing weld cracks, and extending the service life of the power tower. Furthermore, the main view section of the swing seat is conical. Under the action of weight, the swing seat will drive the locking block to move to one side of the pull rod and press down the pressure handle. The pressure handle will drive the pull rod to move downward inside the guide groove through the pressure rod. The main view section of the locking groove is triangular. One end of the chamfered locking block will move into the inside of the locking groove, so that the pull rod can be automatically locked during downward movement. This allows the clamping plate to vibrate during welding without loosening, improving welding quality and further extending the service life of the power tower. Furthermore, by using multiple sets of clamping plates to clamp the angle steel, the angle steel is subjected to more uniform force, and the welding quality is more stable. Furthermore, after welding is completed, press down the handle to loosen the swing seat. Rotate the swing seat to move the locking block to the outside of the support seat. At this time, loosen the handle. Under the elastic force of the spring, the pull rod will move upward, causing the sliders on both sides of the top of the slide rail to move in the opposite direction, thus freeing the angle steel from the clamping state. The operation is simple and convenient, saving time and effort. Attached Figure Description

A snap-fit ​​block 322 is fixed to the bottom of the swing seat 321 near the support seat 31. The main view section of the swing seat 321 is conical. The end of the snap-fit ​​block 322 away from the swing seat 321 extends through the connecting groove 313 into the interior of the snap-fit ​​groove 371. A chamfer is provided at the end of the snap-fit ​​groove 371 near the pull rod 37. The snap-fit ​​block 322 and the pull rod 37 form a snap-fit ​​connection through the snap-fit ​​groove 371. The slide rail 33 has a pre-reserved groove 331 inside. Limit seats 341 are fixedly installed on both sides of the bottom end of the slider 34. A connecting seat 342 is fixed on one side of the bottom end of the slider 34. The main view section of the limit seat 341 is "Z" shaped. The slider 34 and the slide rail 33 form a sliding structure through the limit seats 341. The connecting seat 342 extends through the pre-reserved groove 331 into the interior cavity 311 and is hinged to one end of the hinge rod 373. A mounting seat 351 is fixedly installed on one side of the fixed plate 35. A movable plate 352 is provided inside the mounting seat 351. A first spring 353 and a second spring 354 are respectively provided on the side of the movable plate 352 near the fixed plate 35. The first spring 353 and the second spring 354... The two spring pieces 354 are provided with interlocking grooves 355 on both sides. The movable plate 352 is fixed with a clamping plate 356 near the mounting base 351. The first spring piece 353 and the second spring piece 354 are arc-shaped. The two sides of the first spring piece 353 and the second spring piece 354 are engaged by the interlocking grooves 355 to form a telescopic structure. One end of the clamping plate 356 passes through the mounting base 351 and is slidably connected to the mounting base 351. The top end of the pull rod 37 extends into the interior of the built-in cavity 311. The bottom end of the pull rod 37 abuts against the top end of the spring 38. The main view section of the snap-fit ​​groove 371 is triangular. One end of the pressure rod 372 passes through the connecting groove 313 and extends to the outside of the pressure handle 36. The pressure rod 372 is located at the bottom end of the pressure handle 36. Reference Figures 5-11As shown, the angle steel is placed between the clamping plates 356 at the top of the slide rail 33. Pressing down the handle 36 causes the handle 36 to drive the pull rod 37 to move downward through the pressure rod 372. This causes the pull rod 37 to drive the slider 34 to slide at the top of the slide rail 33 through the hinge rod 373 and the connecting seat 342. In turn, the slider 34 drives the clamping plate 356 to clamp and fix the angle steel through the fixing plate 35. Reference Figure 10 and Figure 11 As shown, when the fixing plate 35 drives the clamping plate 356 to clamp and fix the angle steel, the first spring 353 and the second spring 354 deform under the squeezing action of the movable plate 352 and the fixing plate 35. Under the elastic force of the first spring 353 and the second spring 354, the clamping plate 356 clamps the angle steel tightly. At the same time, during welding, the angle steel is allowed to expand slightly, reducing the restraint stress and avoiding cracks in the weld. Reference Figure 1 and Figure 4 As shown, rotating the locking handle 15 causes one end of the locking handle 15 to abut against one end of a set of movable seats 12, thereby fixing the set of movable seats 12 to the guide rod 13. When the angle steel expands due to heat, under the sliding connection between the movable seats 12 and the guide rod 13, the unfixed movable seats 12 can slide inside the movable groove 11, increasing the distance between adjacent movable seats 12 and preventing the angle steel from bending slightly when it expands due to heat.

[0019] Reference Figure 8 and Figure 9 As shown, under the action of weight, the main view section of the swing seat 321 is conical. The swing seat 321 will drive the locking block 322 to move to one side of the pull rod 37 and press down the pressure handle 36. The pressure handle 36 will drive the pull rod 37 to move downward inside the guide groove 312 through the pressure rod 372. The main view section of the locking groove 371 is triangular. The chamfered end of the locking block 322 will move into the locking groove 371, so that the pull rod 37 can be automatically locked during the downward movement, so that the clamping plate 356 vibrates during the welding process without loosening, thereby improving the welding quality. Reference Figure 1 As shown, the angle steel is clamped by multiple sets of clamping plates 356, which makes the angle steel more uniformly stressed and the welding quality more stable. Reference Figures 8-10 As shown, after welding is completed, press down the handle 36 to loosen the swing seat 321. Rotate the swing seat 321 to move the locking block 322 to the outside of the support seat 31. At this time, loosen the handle 36. Under the elastic force of the spring 38, the pull rod 37 will move upward, causing the sliders 34 on both sides of the top of the slide rail 33 to move in the opposite direction, so that the angle steel is released from the clamping state. The operation is simple and convenient, saving time and effort.
