Technical Field

[0001] The utility model relates to the technical field of stone processing for steel structure stairs, in particular to a rapid positioning device for paving stones for steel structure stairs. Background Art

[0002] Stairs are widely used due to their minimal support points, high load-bearing capacity, diverse shapes, and high technical content. They are less susceptible to structural interference from columns and floors, providing strong and secure support. Steel staircases are typically installed by welding, and the stair treads are often paved with decorative stone, which requires drilling.

[0003] In the current stone drilling process, positioning is often performed through manual measurement. This method not only requires manual use of tools to measure step by step, but also requires marking the measuring points. During the drilling process, the marked drilling points cannot limit the drill bit, which easily causes the drilling points to shift, and has poor practicality. In order to solve the above technical problems, we have designed a rapid positioning device for laying stones on steel structure stairs. Utility Model Content

The front and rear sides of the plug block 10 are fixedly connected with clamping blocks 11. The extension plate 8 is sleeved and installed on the surface of the plug block 10. The front and rear sides of the extension plate 8 are provided with fixing holes 9. By setting the clamping blocks 11, the extension plate 8 can be fixed to the surface of the plug block 10 after being inserted into the fixing holes 9, thereby achieving a stable connection effect. When it is necessary to continue to lengthen, just The extension plate 8 and the base plate 1 can be staggered and connected one by one to extend wirelessly. The bottom of the base plate 1 is fixedly installed with a fixing component 5. The tops of the base plate 1 and the front and rear sides of the extension plate 8 are provided with sliding grooves 6. The inner cavity of the sliding groove 6 is slidably installed with a sliding seat 7. By setting the sliding groove 6, the sliding seat 7 can be easily limited so that it can slide stably on the surface of the base plate 1 and the extension plate 8, so that the lateral position can be adjusted. The top of the sliding seat 7 is threadedly connected with a bolt 2. The front side of the sliding seat 7 is fixedly connected with a longitudinal rod 3. The surface of the longitudinal rod 3 is sleeved with a positioning component 4. The positioning component 4 includes a sliding sleeve 41 and a positioning cylinder 45.

Then, the solid stone is placed between the clamping plate 52 and the base plate 1, and then the screw 53 is rotated. Under the action of the thread, the clamping plate 52 is driven to move, so that the clamping plate 52 and the base plate 1 clamp the stone, and then the sliding seat 7 is slid. Insert it into the sliding groove 6 and adjust it to the horizontal position of the desired punching position, then tighten the bolt 2 to fix the sliding seat 7 on the surface of the base plate 1 or the extension plate 8. After the fixation is completed, continue to move the sliding sleeve 41 to make it slide on the surface of the longitudinal rod 3 for position adjustment, thereby driving the positioning cylinder 45 to move and adjust it to the longitudinal position of the desired punching position, then tighten the bolt 2 42 to fix the sliding sleeve 41 on the surface of the longitudinal rod 3 to achieve the positioning adjustment effect, and then extend the drilling head into the interior of the positioning cylinder 45 to drill holes in the stone.
