Description

Technical Field

[0001] The present invention relates to the technical field of bridge welding construction, and particularly to a high-altitude welding positioning device for bridges and an automatic deviation correction method for weld tracks. Background Technique

[0002] In bridge construction, after the main body of the bridge and the bridge piers are installed, painting, maintenance, etc. need to be carried out on the side and bottom of the bridge body through a suspended basket construction platform. Since the heights at which construction is required on the bridge body are different during the construction process, it is necessary to adjust the height of the suspended basket construction platform within a certain range. In order to prevent the phenomenon that the lifting speed of the suspended basket construction platform is too fast, causing instability of construction personnel and construction materials, when installing the suspended basket construction platform, the construction platform needs to be hoisted to a preset position by a large hoisting device, and then the construction platform is welded and fixed to the slow-down device; currently, the construction platform and the columns of the slow-down device are generally fixed by welding.

[0003] When adjusting the positioning components of traditional high-altitude welding positioning devices for bridges, most of them use fixed buckles or simple bolt fastening methods. Operators need to manually adjust the position of the clamping plate repeatedly, 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 scenarios, the clamping plate locking structure of traditional devices has insufficient stability and is prone to displacement due to vibrations or external forces in the high-altitude working environment during the welding process, resulting in welding deviations, seriously affecting the welding quality, and even requiring rework, increasing the construction cost and time cost. Therefore, in view of the above problems, a high-altitude welding positioning device for bridges and an automatic deviation correction method for weld tracks are proposed to solve the above problems.

[0017] After the clamping plate 9 is adjusted to the appropriate position, the clamping block 11 is engaged with the clamping 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 with the clamping block 11. The clamping block 11 is fixed at one end of the L-shaped connecting rod 10 and cooperates with the clamping groove 12 on the clamping plate 9.

The square grooves 15 are opened inside the welding sleeve 2, and the first connecting rod 7 rotates on its inner wall, providing a space for the rotation of the first connecting rod 7 and at the same time restricting the rotation range of the first connecting rod 7 to a certain extent to ensure the stability and coordination of the movement of the device. The outside of the first connecting rod 7 is rotatably connected to the inner wall of the square groove 15.

[0021] Refer to Figures 7 to 8 , an auxiliary fixing component is arranged inside the welding sleeve 2. The auxiliary fixing component includes a plurality of connecting bins 16. The connecting bins 16 are fixed to the outside of the welding sleeve 2, providing installation and sliding spaces for components such as the connecting frame 17 and the connecting column 19. It is the basic support structure of the auxiliary fixing component. One side of the connecting bin 16 is fixedly connected to the outside of the welding sleeve 2. A connecting frame 17 is slidably connected to the inside of the connecting bin 16. The connecting frame 17 slides inside the connecting bin 16, and its movement can drive components such as the top column 18 and the connecting column 19 to move, playing a role in transmitting power and adjusting the positions of other components.

[0022] On both the left and right sides of the top end of the connecting frame 17, there are fixed connection top columns 18. The top columns 18 are fixed on both the left and right sides of the top end of the connecting frame 17 and slide in the internal through hole of the welding sleeve 2, which can transfer the movement of the connecting frame 17 to the inside of the welding sleeve 2 and cooperate with other components to achieve the auxiliary fixation of the welding part. Inside the connection bin 16, there is a sliding connection with a connection column 19.

On both the left and right sides of the connection column 19, there are rotatably connected rotating rods 21. One end of the rotating rod 21 is connected to the connection column 19, and the other end is connected to the connecting frame 17.

[0025] On the top of the connecting frame 17, there is a fixed connection with a first spring 22. The first spring 22 is connected between the top of the connecting frame 17 and the outside of the connection bin 16, playing a role of buffering and resetting. When the connecting frame 17 moves, the first spring 22 can absorb part of the 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 connection bin 16. The outside of the top column 18 slides in the internal through hole of the welding sleeve 2. On both the left and right sides of the connecting frame 17, there are fixed connections with second springs 23.

[0026] It can balance the forces on both sides of the connecting frame 17, ensure the stability of the connecting frame 17 during the sliding process, and make it return to the appropriate position after the connecting frame 17 moves. The other end of the second spring 23 is fixedly connected to the inner wall of the connection bin 16. A plurality of sliding grooves 25 are provided inside the welding sleeve 2. The sliding grooves 25 are provided inside the welding sleeve 2 to provide a track for the sliding of the auxiliary plate 24, standardize the movement track of the auxiliary plate 24, and ensure the accuracy and stability of the auxiliary plate 24 during the adjustment process. The outer part of the auxiliary plate 24 is slidably connected to the inner wall of the sliding groove 25. A placement groove 26 is provided inside the mounting seat 1. The placement groove 26 is provided inside the mounting seat 1 and can be used to place some small tools or spare parts related to the welding operation, which is convenient for the operator to pick up during the welding process and improves the operation efficiency.

[0027] Working principle: First, determine the installation position of the mounting seat 1 and firmly install it at the corresponding part of the bridge high altitude where welding operations need to be carried out. By rotating the push plate 4, since the push plate 4 is in a threaded connection with the external thread 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 act on the adjusting ring 5 and push 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 have corresponding movements. An adjusting groove 8 is provided inside the first connecting rod 7, 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 its position and angle accordingly. At this time, the L-shaped connecting rod 10 will also have a corresponding rotating movement through its rotational connection with the first rotating shaft 6. The clamping block 11 fixedly connected to one end of the L-shaped connecting rod 10 will move as the L-shaped connecting rod 10 rotates. When the clamping plate 9 moves to the appropriate position, the clamping block 11 will be engaged with the clamping groove 12 provided on one side of the clamping plate 9, thereby initially locking the position of the clamping plate 9 and enabling the clamping plate 9 to stably be in the current adjustment position. One end of the second connecting rod 13 in the limiting component provided inside the welding sleeve 2 is rotatably connected to the inside of the welding sleeve 2, and the other end is 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 a role in assisting in limiting and supporting to ensure the stability of the clamping plate 9 during the adjustment process and limit 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 plurality of square grooves 15 provided will also cooperate with the rotation and movement of components such as the first connecting rod 7.

[0028] When the whole device needs to be further fixed and stabilized, the connecting frame 17 will produce a sliding action in the connecting bin 16. The top columns 18 fixedly connected to the left and right sides of the top of the connecting frame 17 will slide in the through holes inside the welding sleeve 2 along with the sliding of the connecting frame 17. At the same time, the connecting column 19 slidably connected inside the connecting bin 16 and the two third rotating shafts 20 rotatably connected will drive the rotating rod 21 to produce corresponding rotation and movement. One end of the rotating rod 21 is fixedly connected to the outside of the third rotating 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 inside the connecting bin 16. The auxiliary plate 24 fixedly connected to the top of the connecting column 19 will slide in the chute 25 opened inside the welding sleeve 2 along with the movement of the connecting column 19. 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 will play a role of buffering and resetting during the movement of the connecting frame 17, ensuring that components such as the connecting frame 17 and the auxiliary plate 24 can stably maintain the current state after moving to the appropriate position, and can automatically perform fine adjustment and reset when being interfered by the outside world to a certain extent, so as to realize the auxiliary fixation and stabilization of the welding part, provide more reliable support and positioning for the welding operation. When the externally connected detection device detects that the weld deviates from the predetermined track, the push plate 4 is finely adjusted again, so that the adjusting ring 5 moves again, and then drives components such as the clamping plate 9 to perform corresponding position and angle adjustments to correct the welding position and make the weld return to the correct track. At the same time, the auxiliary plate 24 slides in the chute 25 to perform real-time dynamic fixation and position fine adjustment on the welding part to cooperate with components such as the clamping plate 9 to complete the automatic deviation correction of the weld track, ensuring that the welding operation can be carried out accurately and stably, and improving the welding quality and efficiency.

The bridge high altitude welding positioning device according to claim 3 is characterized in that: The interior of the rotating rod (21) is fixedly connected to the exterior of the third rotating shaft (20), and the other end of the rotating rod (21) is rotatably connected to the interior of the connecting frame (17).

8. The bridge high altitude welding positioning device according to claim 3 is characterized in that: A plurality of slide grooves (25) are provided inside the welding sleeve (2), the outside of the auxiliary plate (24) is slidably connected to the inner wall of the slide groove (25), and a placement groove (26) is provided inside the mounting seat (1).

9. Automatic deviation correction method for bridge high-altitude welding seam trajectory, characterized by: According to any one of claims 1-8, the bridge high-altitude welding positioning device comprises the following steps: S1. During the movement of the push plate (4), it will gradually interact with the adjustment ring (5), pushing the adjustment ring (5) to slide along the axial direction of the welding sleeve (2). As the adjustment ring (5) slides, the first rotating shaft (6) and the first connecting rod (7) will produce corresponding movements; S2. When the clamping plate (9) moves to a suitable position, the clamping block (11) engages with a clamping slot (12) provided on one side of the clamping plate (9), thereby preliminarily locking the position of the clamping plate (9); S3. When the position of the splint (9) changes, the second connecting rod (13) plays an auxiliary limiting and supporting role, ensuring the stability of the splint (9) during the adjustment process and limiting the excessive movement of the splint (9) to a certain extent; S4. When it is detected that the weld deviates from the predetermined trajectory, the push plate (4) is fine-tuned again, so that the adjustment 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 return the weld to the correct trajectory.
