Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for steel structure welding, and in particular to a steel structure welding positioning device. Background Technology

[0002] Currently, in the welding production process of box-type steel columns, the inner partition usually requires two workers to work together to complete the installation and welding: one person is responsible for straightening the inner partition inside the steel column to keep it in the predetermined position and verticality, while the other person performs the welding work at the bottom. This manual operation method has low welding efficiency, and the positioning accuracy is seriously affected by the operator's experience, physical strength and coordination. Utility Model Content

[0003] The purpose of this utility model is to provide a steel structure welding positioning device that is simple in structure, easy to use, and can be operated by a single person to perform welding operations on the inner partition.

[0004] This utility model is achieved through the following measures: A steel structure welding positioning device, characterized in that it includes a movable frame and a positioning component disposed on the movable frame; The mobile frame includes a base plate, on which the positioning component is disposed, and at both ends of the base plate are limit components. The positioning component includes a mounting vertical plate disposed on the base plate, and a pair of connectors are disposed on the side of the mounting vertical plate near the top, and a rectangular sleeve penetrating vertically is disposed at the end of the pair of connectors. The limiting component includes limiting vertical plates disposed at both ends of the base plate, and a through threaded hole is provided on one side of the limiting vertical plate, and a fastening bolt is disposed in the threaded hole.

[0005] The spacing between the limiting vertical plates on both sides matches the width of the bottom steel plate of the box-shaped steel column, and the fastening bolts can further limit the position of the base frame.

[0006] The specific features of this utility model also include: The connector includes a connecting plate, and mounting side plates are provided on both sides of the connecting plate. One side of the mounting side plate is connected to the back plate of the rectangular sleeve by bolts, and the other side of the mounting side plate is connected to the mounting vertical plate by bolts.

[0007] The outer side of the rectangular sleeve is provided with a through threaded hole, and a limit bolt is provided in the threaded hole.

[0008] When welding the box-type steel column, the positioning device is placed at the welding position of the bottom steel plate of the box-type steel column. Then, the inner partition is inserted into the rectangular sleeve (the position of the rectangular sleeve corresponds to the welding position of the inner partition). Then, the bottom plate is horizontally fine-tuned to bring the inner partition to the welding position. The fastening bolts are tightened to fix the position of the bottom plate. The limiting bolts are tightened to clamp and limit the inner partition. Finally, welding is performed. After welding is completed, the fastening bolts and the limiting bolts are loosened, and the bottom plate is lifted upward to disengage the welded inner partition from the rectangular sleeve. Then, it is moved to the next welding position, and the inner partition is supported again for welding.

[0009] The advantages of this utility model are: simple structure, easy to use, and single-person operation of positioning the inner partition for welding. Attached Figure Description
