[0015] Compared with the prior art, the present application has the following beneficial effects:

[0016] 1、The support plate is symmetrically slidingly connected on the welding frame in the transverse direction, a plurality of support shafts are rotationally connected on the support plate, limit wheels are arranged on the support shafts, and limit grooves for placing the side plates are arranged on the limit wheels.

[0017] 2. A support rod is symmetrically connected to the welding frame for sliding along the horizontal direction. A support block is provided at the end of the support rod, which contacts the side panel. The front and rear sides of the welding frame are symmetrically connected to the vertical direction for sliding. A foot pedal is provided at the bottom of the vertical rod. A steering assembly is provided between the vertical rod and the support rod. When the vertical rod slides downward, it can drive the support rod to slide along the horizontal direction under the action of the steering assembly, thereby separating the support block from the side panel. In this structure, during welding, the support block at the end of the support rod supports and limits the side of the side panel placed in the limit groove, avoiding the shaking of the side panel during welding, further ensuring the accuracy of welding and welding. When the wire trough needs to be moved laterally, the welder steps on the foot pedal to drive the vertical rod to slide downward. Under the action of the steering assembly, the support rod slides horizontally to separate the support block from the side panel. After the foot pedal moves downward, it contacts the travel switch, so that the power motor electrically connected to it starts, and then drives the support shaft to rotate, so that the wire trough automatically moves backward. After the wire trough moves, the foot pedal is released, and the support block can slide horizontally and reset under the action of the steering assembly, thereby providing support and limit for the side panel that needs to be welded next time. This simplifies the operating steps of supporting the side panel and moving the wire trough during welding, and improves the convenience of welding.

[0018] 3. The symmetrical rotation on the welding frame is connected to the turning frame. After the welding of the external connection of the wire trough is completed, the support shaft is used to drive the wire trough to move, so that the wire trough is respectively extended into the clamping holes on the turning frames on both sides. At this time, the two clamping plates in the clamping holes move relative to each other until they contact the upper and lower sides of the wire trough to achieve clamping and fixing of the wire trough. After that, the two clamping plates rise, so that the wire trough is out of the limiting groove on the limiting wheel. After that, the turning frame rotates 180 degrees to realize the turning of the wire trough, so that the inside of the wire trough is exposed, the two clamping plates descend, and at the same time, the support plates on both sides move back to each other, so that the bottom plate of the flipped wire trough contacts the position on the other side of the support plate after it descends. The support shaft is driven by a power motor to rotate, which can realize the movement drive of the wire trough. At the same time, the support plates on the support shaft can limit the positions on both sides of the wire trough to ensure the stability of the movement of the wire trough. After welding is completed, the support shaft drives the wire trough to move to the conveyor belts on both sides to realize automatic unloading of the wire trough after welding. No lifting equipment is required during the welding process, making the turning and movement of the wire trough more convenient and safe, greatly improving the efficiency of the welding process.

[0029] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0030] Reference Figure 1 and Figure 3The present invention is a welding device for heating furnace wire duct, the main structure includes a welding frame 2 for welding the wire duct 1, the wire duct 1 is a trough structure for supporting and protecting pipelines on the heating furnace, the welding frame 2 is a platform for welding processing, and the specific longitudinal section of the welding frame 2 is U-shaped, which is convenient for providing support for welding and leaving enough space for the arrangement of internal components. The wire duct 1 includes a bottom plate 3 and side plates 4 arranged on both sides of the bottom plate 3. The longitudinal section of the wire duct 1 is U-shaped, and the bottom plate 3 at the bottom is connected to the side plates 4 on both sides by welding. The welding frame 2 is symmetrically connected to a support plate 5 that slides laterally. The support plate 5 is a plate-like structure that extends vertically and can slide laterally relative to the welding frame 2. The support plate 5 is rotatably connected to a plurality of support shafts 6 through bearings. The support shafts 6 pass through the support plate 5 in the transverse direction and are rotatably connected thereto, so that the two ends of the support shafts 6 are respectively located on both sides of the support plate 5. The position of the support shaft 6 on one side of the support plate 5 is fixed with a limiting wheel 7 by welding or bolts. The limiting wheel 7 is located between the support plate 5 and the side wall of the welding frame 2, and the limiting wheel 7 is provided with The limiting groove 8 for placing the side panel 4 is recessed inwardly by the surface of the limiting wheel 7. When the wire trough 1 is welded, the side panel 4 of the wire trough 1 is placed vertically in the limiting groove 8 on the limiting wheel 7. The limiting groove 8 is used to limit the vertical position of the side panel 4, thereby improving the accuracy of the wire trough 1 during welding. When welding, the external connection of the wire trough 1 is welded first, so that the wire trough 1 after welding is inverted U-shaped and buckled on the limiting wheels 7 on both sides. The front and rear sides of the welding frame 2 are symmetrically connected to the support along the horizontal sliding direction. Rod 9, the support rod 9 extends laterally and can slide laterally relative to the welding frame 2. The end of the support rod 9 is fixed with a support block 10 by welding or bolts. The support block 10 is in contact with the side of the side panel 4. With this structure, when the side panel 4 is vertically placed inside the limiting groove 8 on the limiting wheel 7, the support rod 9 slides laterally so that the support block 10 at its end contacts the side panel 4, thereby providing support for the side panel 4 in the limiting groove 8, avoiding the side panel 4 from deflecting or shaking during welding, and further improving the accuracy of welding;

[0031] The front and rear sides of the welding frame 2 are symmetrically connected with vertical rods 11 along the vertical sliding. The vertical rods 11 and the side surfaces of the welding frame 2 are matched with each other in the vertical sliding. Preferably, a through hole is provided on the welding frame 2, and a cross bar is slidably connected in the through hole. The cross bar is connected to the vertical rods 11 on both sides to realize the synchronous vertical sliding of the vertical rods 11 on both sides. The bottom of the vertical rod 11 is fixed with a foot pedal 12 by welding or bolts. The welder can step on the foot pedal 12 with his foot to drive the vertical rod 11 to slide downward. A steering assembly is provided between the vertical rod 11 and the support rod 9. The steering assembly can convert the vertical sliding movement of the vertical rod 11 into the horizontal movement of the support rod 9. When the vertical rod 11 slides downward, it can drive the support rod 9 to slide horizontally under the action of the steering assembly, so that the support block 10 is separated from the side panel 4. Such a structure allows the support block 10 at the end of the support rod 9 to contact the side of the side panel 4 during welding to provide support for welding. When the welding of the external connections between the adjacent side panels 4 and the side panels 4 and the bottom panel 3 is completed, it is necessary to move the welded part of the wire trough 1, so that the welder can continue to perform the welding operation without moving the position. During this process, the welder steps on the foot pedal 12 with his foot, and drives the support rod 9 to move horizontally under the action of the steering assembly, so that The support block 10 at the end of the support rod 9 is automatically separated from the side panel 4, ensuring the smoothness of the lateral movement of the welded side panel 4, so that the support block 10 will not interfere with the movement of the side panel 4. The welding frame 2 is fixed with a power motor 13 for driving the support shaft 6 to rotate by welding or bolts. The specific multiple support shafts 6 are connected by gears and chains. The output shaft of the power motor 13 is connected to one of the support shafts 6 by gears and chains, so that the power motor 13 can simultaneously drive the rotation of multiple support shafts 6. A travel switch 14 electrically connected to the power motor 13 is provided under the foot pedal 12. The travel switch 14 is a travel switch 14 commonly used in the prior art. When the foot pedal 12 moves downward and contacts the travel switch 14, the travel switch 14 electrically connected to the power motor 13 is triggered, so that the circuit where the power motor 13 is located is connected, and the power motor 13 drives the multiple support shafts 6 to rotate, so that the welded part of the wire trough 1 moves along the limit grooves 8 on the multiple limit wheels 7. The welder only needs to step on the foot pedal 12 to simultaneously achieve the separation of the support block 10 and the side plate 4 and the movement of the side plate 4 on the multiple limit wheels 7, which greatly simplifies the operating steps of the welder, reduces the welding workload, and improves the convenience of welding.

[0032] The welding frame 2 is symmetrically connected to a turning frame 15 for vertically moving and turning the wire trough 1. The turning frame 15 is rotatably connected to the welding frame 2 through any existing structure. The turning frame 15 is provided with a clamping hole 16 for the wire trough 1 to pass through. The clamping hole 16 passes through the turning frame 15. A clamping plate 17 is symmetrically connected to the clamping hole 16 along the vertical sliding direction. The clamping plates 17 on the upper and lower sides are respectively in contact with the upper and lower sides of the wire trough 1. Figure 8 When all the connections on the outside of the wire trough 1 are welded, the power motor 13 is used to drive the support shaft 6 to rotate, so that both ends of the wire trough 1 pass through the clamping holes 16 on the turning frames 15 on both sides, and then the clamping plates 17 on the upper and lower sides of the clamping holes 16 slide relatively until they contact the upper and lower sides of the wire trough 1, so that the wire trough 1 and the clamping plates 17 on both sides are relatively fixed. At this time, the clamping plates 17 move upward to lift the wire trough 1, so that the wire trough 1 is separated from the limiting groove 8 on the limiting wheel 7, and then the turning frames 15 on both sides rotate 180 degrees to achieve the alignment of the wire trough 1. The wire trough 1 is flipped so that it is U-shaped and located on the welding frame 2, thereby exposing the inner side of the wire trough 1, which is convenient for welding the internal connection of the wire trough 1. After the wire trough 1 is flipped, the bottom plate 3 contacts the position on the support shaft 6 on the other side of the support plate 5. After the wire trough 1 is flipped, the support plates 5 on both sides slide back to each other, so that the distance between the limiting wheels 7 on both sides becomes larger, so that the distance between the support shafts 6 on the other side of the two support plates 5 is adapted to the width of the wire trough 1. At this time, the clamping plate 17 is lowered to drive the wire trough 1 to move downward until the bottom plate 3 and the support shafts on both sides are in contact. The position on the shaft 6 located on the other side of the support plate 5 is in contact, and then the clamping plates 17 on the upper and lower sides slide back to each other, so that the wire trough 1 can be completely placed on the support shafts 6 on both sides. At this time, the wire trough 1 has been preliminarily welded, so the support of the support block 10 is not required for subsequent welding. The wire trough 1 is located on the support shafts 6 on both sides. When the support shafts 6 rotate, the support plates 5 on both sides can limit the position of the wire trough 1, so that the wire trough 1 can accurately move laterally along the welding frame 2, and then repeat the welding steps to achieve the welding operation of the internal connection of the wire trough 1. 2 is provided with conveyor belts 18 on both sides of the turning frame 15. The conveyor belts 18 can adopt a chain or belt conveyor structure. After the internal welding of the wire trough 1 is completed, the power motor 13 is used to drive the support shaft 6 to rotate, so that the wire trough 1 moves horizontally, passes through the clamping hole 16 on the turning frame 15, and then moves to the conveyor belt 18, thereby quickly realizing the unloading of the wire trough 1 after welding, greatly reducing the workload and difficulty of the welding operation, and no lifting equipment is required for turning and moving, which greatly improves the efficiency and convenience of welding processing of the wire trough 1.

[0033] Preferably, the side surfaces of the welding frame 2 are symmetrically provided with sliding sleeves 19, and the support rod 9 is connected in the sliding sleeves 19 along the transverse sliding direction. The sliding sleeves 19 guide and limit the sliding of the support rod 9, thereby improving the stability of the transverse sliding structure of the support rod 9. A compression spring 20 is provided between the end of the support rod 9 and the end of the sliding sleeve 19. When the vertical rod 11 slides downward, it can drive the support rod 9 to slide transversely under the action of the steering assembly, thereby compressing the compression spring 20. When the foot pedal 12 is stepped on and the vertical rod 11 is driven to slide downward, such a structure causes the support rod 9 to slide transversely under the action of the steering assembly, compressing the compression spring 20, so that the support block 10 at the end of the support rod 9 is separated from the side panel 4, thereby facilitating the movement of the welded side panel 4. After welding is completed, the welder releases the foot pedal 12, and the support rod 9 automatically slides and resets horizontally under the reset elastic force of the compression spring 20, so that the support block 10 slides and resets horizontally to the support position, providing limit and support for the subsequent welding of the side panel 4. Under the action of the steering assembly, the vertical rod 11 also automatically slides and resets upward, so that the foot pedal 12 is automatically separated from the travel switch 14, and the circuit where the power motor 13 is located is automatically disconnected, so that the welded part of the wire trough 1 automatically stops moving, making the movement control of the support block 10 more convenient and the movement control of the welded part of the wire trough 1 smoother. The whole process only requires stepping on the foot pedal 12 with the foot, which further simplifies the operating steps of the welder and improves the convenience of the welding operation.

[0034] Preferably, refer to Figure 2 The welding frame 2 is symmetrically fixed with a slip ring 21 by welding or bolts, and the support rod 9 passes through the slip ring 21 and is slidably connected thereto. The upper and lower sides of the slip ring 21 are fixed with connecting plates 22 by welding or bolts to the upper and lower sides of the sleeve 19. The steering assembly is arranged between the left and right sides of the support rod 9 and the vertical rod 11. Such a structure makes the left and right sides of the sliding guide structure composed of the sleeve 19 and the slip ring 21 open, and the steering assembly is arranged at the open position, which can facilitate the contact between the support rod 9 and the vertical rod 11, making the operation of the steering assembly smoother and more stable.

[0035] Preferably, the steering assembly includes a first driving block 23 symmetrically fixed to the left and right sides of the support rod 9 by welding or bolts, and a second driving block 24 symmetrically fixed to the left and right sides of the vertical rod 11 by welding or bolts. The first driving block 23 is provided with a first inclined surface 25, and the second driving block 24 is provided with a second inclined surface 26 that is in sliding contact with the first inclined surface 25. The first inclined surface 25 is in sliding contact with the second inclined surface 26. In this way, when the vertical rod 11 slides downward, the second inclined surface 26 on the second driving block 24 can generate a lateral thrust on the first inclined surface 25 on the first driving block 23, thereby driving the support rod 9 connected to the first driving block 23 to slide laterally, thereby realizing the conversion of the vertical sliding movement of the vertical rod 11 into the lateral sliding movement of the support rod 9, making the steering process smoother and the lateral sliding drive of the support rod 9 smoother and more stable.

[0036] Preferably, refer to Figure 4 and Figure 5 , one of the limiting wheels 7 is located on the sliding path of the support block 10, so that the limiting wheel 7 can be used to limit the maximum distance of the lateral sliding of the support block 10, and a protrusion 27 is fixed on the support block 10 by welding or bolts. When the support block 10 contacts the limiting wheel 7, the protrusion 27 contacts the side of the side plate 4. In this structure, only when the side plate 4 is located inside the limiting groove 8 on the limiting wheel 7, the support block 10 can contact the side of the side plate 4 to support and limit the side plate 4, and when the wire trough 1 is flipped When the bottom plate 3 is located on the support shaft 6 between the support plates 5 on both sides, the support plates 5 on both sides slide back to back, causing the limiting wheel 7 to move away from the side plate 4 of the wire trough 1. The limiting wheel 7 pushes the support block 10 in contact with it to move in the direction away from the side plate 4, so that the protrusion 27 on the support block 10 will not contact the side plate 4, so that when the connection inside the wire trough 1 is welded, the support block 10 automatically moves away from the side plate 4, reducing the possible interference with the movement of the wire trough 1 and further improving the accuracy of the movement control of the support block 10.

[0037] Preferably, the welding frame 2 is symmetrically provided with a through notch 28, and the flip frame 15 is rotatably connected at the notch 28. The notch 28 limits the rotation of the flip frame 15, thereby improving the stability of the rotational movement of the flip frame 15. The notch 28 is rotatably connected to a plurality of supporting wheels 29 through bearings. The longitudinal section of the flip frame 15 is circular, and the edge of the lower half of the flip frame 15 is in rolling contact with the supporting wheel 29. Preferably, a groove is provided on the surface of the supporting wheel 29, and the flip frame 15 is in rotational contact with the groove, thereby effectively limiting the rotational position of the flip frame 15. Such a structure enables the bottom of the flip frame 15 to be rotationally supported by the plurality of supporting wheels 29 when the flip frame 15 rotates, thereby further improving the smoothness of the rotation of the flip frame 15.

[0038] Preferably, refer to Figure 6A ring gear 30 is fixed to the side of the flip frame 15 by welding or bolts, and a flip motor 31 is fixed to the notch 28 by welding or bolts. A driving gear 32 meshing with the ring gear 30 is fixed to the output shaft of the flip motor 31 by welding. The driving gear 32 contacts the bottom inside the ring gear 30, thereby pressing the ring gear 30 down onto the multiple supporting wheels 29. When the flip motor 31 is started, the driving gear 32 and the ring gear 30 are meshed and drive the ring gear 30 and the flip frame 15 to rotate, making the rotation drive of the flip frame 15 more stable and smooth.

[0039] Preferably, a telescopic rod 33 is symmetrically fixed in the clamping hole 16 by welding or bolts, and the clamping plate 17 is fixed to the movable end of the telescopic rod 33 by welding or bolts. The specific telescopic rod 33 can adopt an electric cylinder or an oil cylinder structure. The telescopic movement of the telescopic rod 33 is used to drive the clamping plate 17 to slide vertically in the clamping hole 16, thereby clamping and fixing the wire trough 1. The structure is simple, and the clamping and fixing of the wire trough 1 is more efficient and stable.

[0040] Preferably, a plurality of guide columns 34 are fixed to the support plate 5 by welding or bolts, and a plurality of penetrating guide holes 35 are provided on the side of the welding frame 2, and the guide columns 34 are slidably connected in the guide holes 35. Such a structure enables the support plate 5 to achieve a sliding connection with the welding frame 2 through the sliding cooperation between the plurality of guide columns 34 and the guide holes 35 when sliding laterally, thereby greatly improving the stability of the sliding structure of the support plate 5. A plurality of telescopic components are provided between the support plate 5 and the welding frame 2. The telescopic components can adopt any power device capable of telescopic movement in the prior art, thereby achieving a more stable and efficient lateral sliding movement of the support plate 5 relative to the welding frame 2.

[0041] Preferably, refer to Figure 7 The telescopic component is a scissor-type telescopic frame 36, which is powered by a motor or a hydraulic column. This telescopic form can occupy a smaller space when retracted, so that the support plate 5 can slide horizontally on the welding frame 2 in a larger range, reducing the space occupancy rate of the equipment, reducing the size of the equipment and reducing the production cost.

[0042] Working principle: The present invention is symmetrically connected to the welding frame 2 along the horizontal sliding with a support plate 5, the support plate 5 is rotatably connected to a plurality of support shafts 6, the support shaft 6 is provided with a limiting wheel 7, and the limiting wheel 7 is provided with a limiting groove 8 for placing the side plate 4. Such a structure can place the side plate 4 of the wire trough 1 in the limiting groove 8 during welding, effectively limiting the position of the side plate 4, thereby ensuring the accuracy of the welding process. After welding the external connection of the wire trough 1, the power motor 13 is used to drive the support shaft 6 to rotate, so that the welding of the wire trough 1 can be completed. The part moves along the limiting groove 8 on the limiting wheel 7, so that the wire duct 1 after welding is moved backward to vacate the welding station. At this time, the welder only needs to stand in place to continue the subsequent welding of the side panels 4 and the bottom panel 3, which greatly reduces the welding workload and improves the convenience of welding. Support rods 9 are symmetrically connected to the welding frame 2 along the horizontal sliding direction. The end of the support rod 9 is provided with a support block 10 in contact with the side panel 4. The front and rear sides of the welding frame 2 are symmetrically connected to the vertical sliding direction with vertical rods 11. The bottom of the vertical rod 11 is provided with a foot pedal 12 , a steering assembly is provided between the vertical rod 11 and the support rod 9. When the vertical rod 11 slides downward, it can drive the support rod 9 to slide horizontally under the action of the steering assembly, so that the support block 10 is separated from the side plate 4. Such a structure supports and limits the side of the side plate 4 placed inside the limiting groove 8 during welding, avoiding the shaking of the side plate 4 during welding, further ensuring the accuracy of welding. When the wire duct 1 needs to be moved after welding, the welder steps on the foot pedal 12 with his foot to drive the vertical rod 11 to slide downward. Under the action of the steering assembly, the support rod 9 slides horizontally so that the support block 10 is separated from the side panel 4. After the foot pedal 12 moves downward, it contacts the travel switch 14, so that the power motor 13 electrically connected thereto is started, thereby driving the support shaft 6 to rotate, so that the wire trough 1 automatically moves backward.
