Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge welding construction, in particular to a bridge high-altitude welding positioning device and a welding seam track automatic deviation correction method. BACKGROUND

[0002] In bridge construction, after the bridge body and bridge piers are installed, the bridge body side and bottom need to be painted, maintained and repaired through a basket-type construction platform. Because the height of the bridge body to be constructed is different during construction, the height of the basket-type construction platform needs to be adjusted within a certain range. In order to prevent the phenomenon of instability of construction personnel and construction materials caused by too fast lifting speed of the basket-type construction platform, the construction platform needs to be welded and fixed with a slow descent device when the platform is installed by large hoisting equipment and hoisted to the preset position. At present, the column between the construction platform and the slow descent device is generally fixed by welding.

[0003] The traditional bridge high-altitude welding positioning device mostly adopts fixed buckles or simple bolt fastening methods when adjusting the positioning components. The operator needs to repeatedly manually adjust the position of the clamping plate, which not only has low adjustment efficiency, but also is difficult to achieve precise adaptation to welding components of different sizes. When encountering complex welding scenes, the clamping plate locking structure of the traditional device has insufficient stability and is prone to displacement in the welding process due to vibration or external force in the high-altitude working environment, resulting in welding deviation, which seriously affects the welding quality and even requires rework, increasing construction cost and time cost. Therefore, the bridge high-altitude welding positioning device and the welding seam track automatic deviation correction method are proposed to solve the above problems. SUMMARY

[0004] The purpose of the present application is to provide a bridge high-altitude welding positioning device and a welding seam track automatic deviation correction method to solve the problems raised in the background.

[0005] To achieve the above purpose, the present application provides a bridge high-altitude welding positioning device, which comprises a mounting seat, an external welding sleeve fixedly connected to the mounting seat, an external thread groove provided on the outside of the welding sleeve, a push plate threadedly connected to the outside of the external thread groove, an adjusting ring slidingly connected to the outside of the welding sleeve, a plurality of first shafts rotatably connected to the inside of the adjusting ring, a plurality of first connecting rods rotatably connected to the outside of the adjusting ring, an adjusting groove provided in the inside of the first connecting rod, a clamping plate rotatably connected to one end of the first connecting rod, an L-shaped connecting rod rotatably connected to the outside of the first shaft, a clamping block fixedly connected to one end of the L-shaped connecting rod, a limiting assembly provided in the inside of the welding sleeve, and an auxiliary fixing assembly provided in the inside of the welding sleeve.

[0006] Preferably, the limiting component includes a plurality of second connecting rods, one end of the second connecting rod is rotatably connected to the inside of the welding sleeve, the other end of the second connecting rod is rotatably connected to the outside of the clamping plate, a slot is provided on one side of the clamping plate, a second rotating shaft is rotatably connected to the inside of the welding sleeve, and a plurality of square grooves are provided inside the welding sleeve.

[0007] Preferably, the auxiliary fixing assembly includes multiple connecting chambers, one side of which is fixedly connected to the outside of the welding sleeve, a connecting frame is slidably connected inside the connecting chamber, top columns are fixedly connected to the top left and right sides of the connecting frame, a connecting column is slidably connected inside the connecting chamber, two third rotating shafts are rotatably connected inside the connecting chamber, rotating rods are rotatably connected to the left and right sides of the connecting column, and the top of the connecting column is fixedly connected to the auxiliary plate;

[0008] Preferably, a first spring is fixedly connected to the top of the connecting frame, the other end of the first spring is fixedly connected to the outside of the connecting chamber, the outside of the top column is slidably connected to the inside through hole of the welding sleeve, and a second spring is fixedly connected to both the left and right sides of the connecting frame, the other end of the second spring is fixedly connected to the inner wall of the connecting chamber.

[0009] Preferably, the inside of the adjusting groove is slidably connected to the outside of the first rotating shaft, and the outside of the first connecting rod is rotatably connected to the inner wall of the square groove;

[0010] Preferably, the outer side of the card block engages with the inner wall of the card slot, and the inner side of the first connecting rod is rotatably connected to the outer side of the second rotating shaft;

[0011] Preferably, the inside of the rotating rod is fixedly connected to the outside of the third rotating shaft, and the other end of the rotating rod is rotatably connected to the inside of the connecting frame;

[0012] Preferably, the welding sleeve has multiple sliding grooves inside, the auxiliary plate is slidably connected to the inner wall of the sliding grooves outside, and the auxiliary plate has a placement groove inside.

[0013] The automatic correction method for weld trajectory of high-altitude bridge welding, based on the above-mentioned high-altitude bridge welding positioning device, includes the following steps;

[0014] S1. During the movement of the push plate, it will gradually interact with the adjusting ring, pushing the adjusting ring to slide along the axial direction of the welding sleeve. As the adjusting ring slides, the first rotating shaft and the first connecting rod will produce corresponding actions.

[0015] S2. When the clamping plate moves to the appropriate position, the locking block will engage with the locking slot opened on one side of the clamping plate, thereby initially locking the position of the clamping plate.

[0016] S3. When the position of the clamp changes, the second link will play an auxiliary limiting and supporting role to ensure the stability of the clamp during the adjustment process and to a certain extent limit the excessive movement of the clamp.

[0017] S4. When the weld is detected to deviate from the predetermined trajectory, the push plate is finely adjusted again, causing the adjusting ring to move again, which in turn drives the clamping plate and other components to make corresponding position and angle adjustments to correct the welding position and bring the weld back to the correct trajectory.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the adjustment groove inside the first connecting rod cooperates with the first rotating shaft, and the L-shaped connecting rod drives the locking block to engage with the locking groove, thereby realizing the precise adjustment and initial locking of the clamping plate position. This enables the clamping plate to adapt to welding parts of different sizes and shapes, greatly improving the versatility of the device. The stable initial locking can effectively prevent the clamping plate from shifting during the welding process, avoiding welding deviations caused by inaccurate positioning, and providing a solid guarantee for high-quality welding operations.

[0020] 2. In this invention, the sliding structure of the connecting frame within the connecting chamber drives the top column to slide within the through hole of the welding sleeve. Simultaneously, the cooperation of the rotating rod with the third rotating shaft and the connecting column drives the auxiliary plate to slide within the groove. Furthermore, the first and second springs act as buffers and resets, achieving auxiliary fixation and dynamic fine-tuning of the welding part. During the welding process, auxiliary fixation enhances the stability of the welding part and reduces welding defects caused by factors such as vibration. Dynamic fine-tuning allows for precise adjustment based on real-time changes in the weld trajectory, ensuring a uniform and aesthetically pleasing weld. This significantly improves welding quality and efficiency and reduces the defect rate. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 One embodiment of the present invention provides a bridge high-altitude welding positioning device, including a mounting base 1. The mounting base 1 serves as the basic support structure of the entire bridge high-altitude welding positioning device, providing a stable installation platform for the device and ensuring that the device can be firmly fixed in the designated position in the high-altitude bridge working environment, avoiding the impact of shaking or displacement on the accuracy of welding positioning and weld trajectory correction. A welding sleeve 2 is fixedly connected to its exterior. The welding sleeve 2 is one of the core structures of the device. On the one hand, it provides space and support for the installation and movement of other components such as the adjusting ring 5 and the push plate 4; on the other hand, its interior can accommodate welding-related tools or components, providing operating space for welding operations.

[0033] An automatic correction method for the trajectory of weld seams in high-altitude bridge welding, based on a high-altitude bridge welding positioning device, includes the following steps:

[0034] S1. During the movement of the push plate 4, it will gradually interact with the adjusting ring 5, pushing the adjusting ring 5 to slide along the axial direction of the welding sleeve 2. As the adjusting ring 5 slides, the first rotating shaft 6 and the first connecting rod 7 will produce corresponding actions.

[0035] S2. When the clamping plate 9 moves to the appropriate position, the locking block 11 will engage with the locking slot 12 opened on one side of the clamping plate 9, thereby initially locking the position of the clamping plate 9.

[0036] S3. When the position of the clamping plate 9 changes, the second link 13 will play an auxiliary limiting and supporting role to ensure the stability of the clamping plate 9 during the adjustment process and to a certain extent limit the excessive movement of the clamping plate 9.

[0037] S4. When the weld is detected to deviate from the predetermined trajectory, the push plate 4 is finely adjusted again, causing the adjusting ring 5 to move again, which in turn drives the clamping plate 9 and other components to make corresponding position and angle adjustments to correct the welding position and bring the weld back to the correct trajectory.

[0038] The welding sleeve 2 has an external threaded groove 3 on its outside. The external threaded groove 3 is located on the outside of the welding sleeve 2 and is connected to the threaded connection of the push plate 4. Through the threaded transmission principle, the rotational motion of the push plate 4 can be converted into linear motion along the axial direction of the welding sleeve 2, thereby providing power for the adjustment of subsequent components. The external threaded groove 3 is connected to the push plate 4. Through the threaded connection with the external threaded groove 3, the operator can control the position movement of the push plate 4 on the welding sleeve 2 by rotating it, thereby driving the movement of components such as the adjusting ring 5, and realizing the adjustment of the position of the clamping plate 9 and other structures.

[0039] An adjusting ring 5 is slidably connected to the outside of the welding sleeve 2. The adjusting ring 5 can slide outside the welding sleeve 2, and its sliding can drive the first rotating shaft 6 and the first connecting rod 7 connected to it to move. It plays the role of transmitting power and adjusting the position of other components. It is a key intermediate structure for realizing the position adjustment of the clamping plate 9. Multiple first rotating shafts 6 are rotatably connected inside the adjusting ring 5. The first rotating shafts 6 are rotatably connected inside the adjusting ring 5. They not only provide connection points for the movement of the adjusting ring 5 and the first connecting rod 7, but can also slide in the adjusting groove 8. With the rotation of the first connecting rod 7, the position and angle of the clamping plate 9 can be precisely adjusted.

[0040] Multiple first connecting rods 7 are rotatably connected to the outside of the adjusting ring 5. One end of the first connecting rod 7 is rotatably connected to the clamping plate 9, and the other end cooperates with the first rotating shaft 6 through the adjusting groove 8 and rotates within the square groove 15. This allows the movement of the adjusting ring 5 to be transmitted to the clamping plate 9, enabling the clamping plate 9 to adjust its position and angle to adapt to different welding requirements. The adjusting groove 8 is provided inside the first connecting rod 7 and is slidably connected to the first rotating shaft 6, providing a sliding track for the first rotating shaft 6. This allows the first connecting rod 7 to adjust its angle and position according to the position change of the first rotating shaft 6 during movement, ensuring the flexibility and accuracy of the clamping plate 9 adjustment.

[0041] Reference Figures 4 to 6The adjustment groove 8 is internally slidably connected to the outside of the first rotating shaft 6. One end of the first connecting rod 7 is rotatably connected to a clamping plate 9. The clamping plate 9 directly acts on the welding part. By adjusting its position and angle, the welding part can be positioned and clamped to ensure the stability of the part during the welding process and avoid welding deviation caused by the movement of the part. The outside of the first rotating shaft 6 is rotatably connected to an L-shaped connecting rod 10. The L-shaped connecting rod 10 is rotatably connected to the first rotating shaft 6. The locking block 11 at one end of the L-shaped connecting rod 10 can engage with the locking groove 12 when the L-shaped connecting rod 10 rotates, thereby locking the position of the clamping plate 9.

[0042] After the clamping plate 9 is adjusted to the appropriate position, the locking block 11 engages with the locking groove 12 to prevent the clamping plate 9 from shifting during the welding process. One end of the L-shaped connecting rod 10 is fixedly connected to the locking block 11. The locking block 11 is fixed to one end of the L-shaped connecting rod 10 and cooperates with the locking groove 12 on the clamping plate 9. After the clamping plate 9 is adjusted to the appropriate position, the locking block 11 engages with the locking groove 12 to lock the position of the clamping plate 9 and ensure the stability of the clamping plate 9 during the welding process. The locking groove 12 is opened on one side of the clamping plate 9 and is adapted to the locking block 11. When the locking block 11 engages with the locking groove 12, it can fix the position of the clamping plate 9 and prevent it from moving due to external force during the welding process, thus ensuring the accuracy of welding positioning.

[0043] The outer side of the locking block 11 engages with the inner wall of the locking groove 12. The inside of the welding sleeve 2 is provided with a limiting component, which includes multiple second connecting rods 13. One end of the second connecting rod 13 is connected to the inside of the welding sleeve 2, and the other end is connected to the outside of the clamping plate 9, which serves to assist in limiting and support the clamping plate 9.

[0044] During the adjustment and welding process of clamping plate 9, excessive movement of clamping plate 9 is restricted to ensure the stability and accuracy of its movement. One end of the second connecting rod 13 is rotatably connected to the inside of welding sleeve 2, and the other end of the second connecting rod 13 is rotatably connected to the outside of clamping plate 9. The inside of welding sleeve 2 is rotatably connected to a second rotating shaft 14, which is rotatably connected inside welding sleeve 2. The first connecting rod 7 rotates around it, providing a support point for the rotation of the first connecting rod 7, regulating the rotation trajectory of the first connecting rod 7, and helping to achieve precise adjustment of clamping plate 9.

[0045] The first connecting rod 7 is internally rotatably connected to the outside of the second rotating shaft 14. The welding sleeve 2 has multiple square grooves 15 inside. The square grooves 15 are located inside the welding sleeve 2, and the first connecting rod 7 rotates on its inner wall, providing space for the rotation of the first connecting rod 7. At the same time, the rotation range of the first connecting rod 7 is limited to a certain extent to ensure the stability and coordination of the device movement. The outside of the first connecting rod 7 is rotatably connected to the inner wall of the square grooves 15.

[0046] Reference Figures 7 to 8The welding sleeve 2 is equipped with an auxiliary fixing component, which includes multiple connecting chambers 16. The connecting chambers 16 are fixed to the outside of the welding sleeve 2, providing space for the installation and sliding of components such as the connecting frame 17 and the connecting column 19. They are the basic support structure of the auxiliary fixing component. One side of the connecting chamber 16 is fixedly connected to the outside of the welding sleeve 2. The connecting frame 17 is slidably connected inside the connecting chamber 16. The connecting frame 17 slides inside the connecting chamber 16, and its movement can drive the top column 18, the connecting column 19 and other components to move, playing the role of transmitting power and adjusting the position of other components.

[0047] Top columns 18 are fixedly connected to the top left and right sides of the top of the connecting frame 17. The top columns 18 are fixed to the top left and right sides of the top of the connecting frame 17 and slide in the through hole inside the welding sleeve 2. They can transmit the movement of the connecting frame 17 to the inside of the welding sleeve 2 and work with other components to achieve auxiliary fixation of the welding part. A connecting column 19 is slidably connected inside the connecting chamber 16. The connecting column 19 slides in the connecting chamber 16 and is connected to the connecting frame 17 through the rotating rod 21. Its movement can drive the auxiliary plate 24 to move and is the intermediate structure for adjusting the position of the auxiliary plate 24.

[0048] The connecting chamber 16 has two third rotating shafts 20 rotatably connected inside. The third rotating shafts 20 are rotatably connected inside the connecting chamber 16, and the rotating rod 21 rotates around them, providing a support point for the rotation of the rotating rod 21, regulating the rotation trajectory of the rotating rod 21, and ensuring the stability of the movement of the auxiliary fixing component. The left and right sides of the connecting column 19 are rotatably connected to the rotating rod 21. One end of the rotating rod 21 is connected to the connecting column 19, and the other end is connected to the connecting frame 17. By rotating around the third rotating shaft 20, the movement of the connecting frame 17 is transmitted to the connecting column 19, realizing the linkage and position adjustment between the components.

[0049] The rotating rod 21 is internally fixedly connected to the outside of the third rotating shaft 20, and the other end of the rotating rod 21 is rotatably connected to the inside of the connecting frame 17. The top of the connecting column 19 is fixedly connected to the auxiliary plate 24. The auxiliary plate 24 is fixed on the top of the connecting column 19 and slides in the slide groove 25. It can directly act on the welding part to assist in fixing and supporting the welding part, enhance the stability of the welding part, and improve the welding quality.

[0050] A first spring 22 is fixedly connected to the top of the connecting frame 17. The first spring 22 is connected to the top of the connecting frame 17 and the outside of the connecting chamber 16, and plays a role in buffering and resetting. When the connecting frame 17 moves, the first spring 22 can absorb some energy and reduce the impact during the movement. When the external force disappears, the first spring 22 can make the connecting frame 17 return to the initial position. The other end of the first spring 22 is fixedly connected to the outside of the connecting chamber 16. The outside of the top column 18 is slidably connected to the internal through hole of the welding sleeve 2. A second spring 23 is fixedly connected to both the left and right sides of the connecting frame 17. The second spring 23 is connected to the left and right sides of the connecting frame 17 and the inner wall of the connecting chamber 16, and also plays a role in buffering and resetting.

[0051] The connecting frame 17 can balance the forces on both sides, ensuring its stability during sliding and returning to its proper position after movement. The other end of the second spring 23 is fixedly connected to the inner wall of the connecting chamber 16. The welding sleeve 2 has multiple sliding grooves 25 inside, which provide a track for the sliding of the auxiliary plate 24, regulate the movement trajectory of the auxiliary plate 24, and ensure the accuracy and stability of the auxiliary plate 24 during adjustment. The auxiliary plate 24 is slidably connected to the inner wall of the sliding grooves 25. The mounting base 1 has a placement groove 26 inside, which can be used to place small tools or spare parts related to welding operations, making it convenient for operators to access them during welding and improving work efficiency.

[0052] Working Principle: First, determine the installation position of the mounting base 1 and securely install it at the corresponding location on the bridge where welding operations will be performed. By rotating the push plate 4, which is threadedly connected to the external threaded groove 3, the push plate 4 will move along the axial direction of the welding sleeve 2. During the movement of the push plate 4, it will gradually interact with the adjusting ring 5, pushing the adjusting ring 5 to slide along the axial direction of the welding sleeve 2. As the adjusting ring 5 slides, the first rotating shaft 6 and the first connecting rod 7 will produce corresponding actions. The first connecting rod 7 has an adjusting groove 8 inside, and the first rotating shaft 6 slides in the adjusting groove 8. At the same time, the clamping plate 9 rotatably connected to one end of the first connecting rod 7 will also change position and angle. At this time, the L-shaped connecting rod 10 will also produce a corresponding rotational action through its rotational connection with the first rotating shaft 6. The locking block 11 fixedly connected to one end of the L-shaped connecting rod 10 will move with the rotation of the L-shaped connecting rod 10. When the clamping plate 9 is moved to the appropriate position, the locking block 11 engages with the locking groove 12 on one side of the clamping plate 9, thereby initially locking the position of the clamping plate 9 and ensuring that the clamping plate 9 can be stably in the current adjustment position. The second connecting rod 13 in the limiting assembly set inside the welding sleeve 2 has one end rotatably connected to the inside of the welding sleeve 2 and the other end rotatably connected to the outside of the clamping plate 9. When the position of the clamping plate 9 changes, the second connecting rod 13 will play an auxiliary limiting and supporting role, ensuring the stability of the clamping plate 9 during the adjustment process and limiting the excessive movement of the clamping plate 9 to a certain extent. At the same time, the second rotating shaft 14 rotatably connected inside the welding sleeve 2 and the multiple square grooves 15 will also cooperate with the rotation and movement of the first connecting rod 7 and other components.

[0053] When the entire device needs further fixation and stabilization, the connecting frame 17 will slide within the connecting chamber 16. The top columns 18, fixedly connected to the left and right sides of the top of the connecting frame 17, will slide within the through holes inside the welding sleeve 2 as the connecting frame 17 slides. Simultaneously, the connecting column 19, which is slidably connected inside the connecting chamber 16, and the two rotatably connected third shafts 20, will drive the rotating rod 21 to rotate and move accordingly. One end of the rotating rod 21 is fixedly connected to the outside of the third shaft 20, and the other end is rotatably connected to the inside of the connecting frame 17. When the connecting frame 17 slides, the rotating rod 21 will push the connecting column 19 to move within the connecting chamber 16. The auxiliary plate 24, fixedly connected to the top of the connecting column 19, will slide within the groove 25 opened inside the welding sleeve 2 as the connecting column 19 moves. The first spring 22 fixedly connected to the top of the connecting frame 17 and the second springs 23 fixedly connected to the left and right sides play a buffering and resetting role during the movement of the connecting frame 17. This ensures that the connecting frame 17 and auxiliary plate 24 and other components can stably maintain their current state after moving to the appropriate position. Furthermore, they can automatically make fine adjustments and reset when subjected to certain external interference, thereby achieving auxiliary fixation and stability of the welding part and providing more reliable support and positioning for the welding operation. When the externally connected detection device detects that the weld seam deviates from the predetermined trajectory, the push plate 4 is finely adjusted again, causing the adjusting ring 5 to move again. This, in turn, drives the clamping plate 9 and other components to make corresponding position and angle adjustments to correct the welding position and bring the weld seam back to the correct trajectory. At the same time, the auxiliary plate 24 slides in the slide groove 25 to perform real-time dynamic fixation and position fine adjustment of the welding part, in order to cooperate with the clamping plate 9 and other components to complete the automatic correction of the weld seam trajectory, ensuring that the welding operation can be carried out accurately and stably, and improving welding quality and efficiency.

When the clamp (9) moves to the appropriate position, the locking block (11) will engage with the locking slot (12) opened on one side of the clamp (9), thereby initially locking the position of the clamp (9); S3. When the position of the clamp (9) changes, the second link (13) will play the role of auxiliary limiting and support, ensuring the stability of the clamp (9) during the adjustment process, and limiting the excessive movement of the clamp (9) to a certain extent. S4. When the weld is detected to deviate from the predetermined trajectory, the push plate (4) is finely adjusted again, so that the adjusting ring (5) moves again, thereby driving the clamping plate (9) and other components to make corresponding position and angle adjustments to correct the welding position and bring the weld back to the correct trajectory.
