[0002] The tension rod in the arch bridge that bears the horizontal thrust of the arch end is called a tie rod. It prevents the arch end support from generating horizontal thrust, making it a thrust-free arch. According to the comparison of the stiffness of the tie rod and the arch rib, it can be divided into rigid tie rods and flexible tie rods. Rigid tie rods are subjected to both tension and compression, while flexible tie rods are only subjected to tension. The length of the tie rod is limited. When the length of a single tie rod is not enough to function, another tie rod is needed to be welded to the previous tie rod. First, it is necessary to manually align one end of the two tie rods, and then use a welding head to weld the two ends.

[0003] The alignment device mainly utilizes a clamping component to clamp one end of the two tie rods, and then moves the position of the welding head to weld the connection between the two tie rods. The alignment device is at a specific height, and welding can only be achieved by moving the position of the welding head. The single movement of the welding head is time-consuming, which slows down the speed of the welding head to reach the welding position, prolongs the time of tie rod welding, and thus reduces the efficiency of the alignment device. Therefore, it is particularly important to design an alignment device for tie rod welding. Summary of the invention

A support rod 16 is fixedly installed on one side of the two clamping rings 17, which will drive the two first straight racks 9 and the second straight racks 10 meshing with them to move. The first straight rack 9 gradually moves upward, and the second straight rack 10 gradually moves downward. Through this structure, the position height of the welding head 4 and the tie rod after alignment can be adjusted at the same time, which speeds up the speed of the welding head 4 reaching the welding position, shortens the welding time, and improves the efficiency of the alignment device. Embodiment 2:

[0023] Based on the first embodiment, Figure 1 and Figure 4 As shown, a rotating rod 18 is rotatably installed on one side of the shelf plate 13, one end of the rotating rod 18 is fixedly connected to one end of the two-way threaded rod 14, and the two fitting blocks 7 are movably sleeved on one end of the two fixed columns 6 respectively. The utility model is an alignment device for tie rod welding, by setting the two-way threaded rod 14, the contact block 15, the support rod 16 and the shelf plate 13. After the two auxiliary plates 8 are subjected to force, they will drive the two fitting blocks 7 to move up and down at one end of the two fixed columns 6 respectively, so that the position height of the welding plate 3 and the shelf plate 13 can be adjusted. Rotating the rotating rod 18 clockwise will drive the two-way threaded rod 14 to rotate synchronously.

[0024] Working principle: The tie rod that bears the horizontal thrust of the arch end in the arch bridge is called a tie rod. It makes the arch end support generate no horizontal thrust, and becomes a thrust-free arch. When the length of a single tie rod is not enough to be used, another tie rod needs to be welded with the previous tie rod. First, it is necessary to manually align one end of the two tie rods, and then use the welding head 4 to weld the two ends. The alignment device is often clamped by the clamping ring 17. The ends of the two tie rods are placed in the middle of the two clamping rings 17. At this time, the tie rod needs The welding position is just at the bottom of the welding head 4. The height of the alignment table 1 is relatively short, which is convenient for the staff to hold the tie rod stably. The two clamping rings 17 can mainly clamp one end of the two tie rods at the same time to align and move them to the position of the welding head 4. Then, after the staff starts the servo motor 11, the gear 12 rotates clockwise, thereby driving the two first straight racks 9 and the second straight racks 10 meshing with it to move. The first straight rack 9 gradually moves upward, and the second straight rack 10 gradually moves downward. Through this structure The height of the position of the welding head 4 and the tie rod after alignment can be adjusted at the same time, that is, after starting the servo motor 11, not only the shelf plate 13 will rise, but the welding head 4 will also gradually fall, which speeds up the speed of the welding head 4 to reach the welding position, shortens the welding time, solves the problem that welding can only be achieved by moving the welding head 4, and improves the efficiency of the alignment device. After the two auxiliary plates 8 are subjected to force, they will drive the two fitting blocks 7 to move up and down at one end of the two fixed columns 6 respectively, so that the height of the position of the welding plate 3 and the shelf plate 13 can be adjusted. One of the auxiliary plates 8 is fixed to one side of the welding plate 3, and the top of the other auxiliary plate 8 is fixed to the bottom of the shelf plate 13. After the rotating rod 18 is rotated clockwise manually, the bidirectional threaded rod 14 will be driven to rotate synchronously, so that the two contact blocks 15 will move relative to each other, so that the distance between the two clamping rings 17 can be adjusted. Through the clamping of the clamping ring 17, the tie rod is more firm, which improves the welding quality of the alignment device. The material set on the inner surface of the clamping ring 17 is sponge, which is relatively soft, reducing the wear of the tie rod.
