This invention proposes a dedicated welding positioning device for height restriction frames, belonging to the field of height restriction frame welding technology. The device includes a tilting frame, a load-bearing plate, a column positioning frame, and a crossbeam positioning frame. The tilting frame is configured to be driven to rotate around its central axis to switch between vertical and horizontal states. Two load-bearing plates are fixedly installed on each tilting frame to support and position the bottom beam and two sets of diagonal braces. The load-bearing plates are configured to rotate synchronously with the tilting frame to switch between vertical and horizontal states. The column positioning frame supports and positions the columns; the crossbeam positioning frame supports and positions the crossbeams; an adjustment push plate is installed on the tilting frame to push the bottom beam to move along its axial direction; an adjustment push plate is also installed on the crossbeam positioning frame, and this adjustment push plate is configured to switch postures to selectively push the columns or crossbeams to move along their axial direction. Specifically, this invention provides a dedicated welding positioning device for height restriction frames that can switch welding states, improving the convenience of welding operations.
