Description

Technical Field

[0001] This utility model relates to the field of adjustable support technology, and in particular to an adjustable support for scaffolding. Background Technology

[0002] Adjustable scaffolding supports are key components used in construction to adjust support height and transfer loads. They are mainly installed at the top of scaffolding uprights to support structural components such as formwork and I-beams, enabling fine-tuning of height and stable load-bearing. The adjustable scaffolding supports achieve precise height adjustment through the threaded transmission of screws and nuts, making them a core component in ensuring the stability of the support system during construction.

[0003] Traditional support brackets adjust height by manually rotating nuts, which is slow and time-consuming. When working at heights, operators need to climb repeatedly, which is physically demanding and carries the risk of falling. Furthermore, without gear reduction or hydraulic assistance, the force required for single-person adjustment is too great, and two people are needed to work together when the threads get stuck, making it even less efficient.

[0016] Reference Figure 1-4 This utility model discloses an adjustable support for scaffolding, comprising a support base plate 1 for supporting the entire workpiece. A protective cover 4 is fixedly connected to the support base plate 1 to prevent dust and other impurities from adhering to the threaded rod 17 and causing rotational jamming. A first bearing 11 is fixedly connected to the protective cover 4, and a first rotating shaft 12 is fixedly connected to the inner wall of the first bearing 11, allowing a first bevel gear 13 to rotate. The first rotating shaft 12 is rotated, and the left end of the first rotating shaft 12 is fixedly connected to the first bevel gear 13. A second bearing 16 is fixedly connected to the support base plate 1, and the second bearing 16 is inside the protective cover 4. A second rotating shaft 14 is fixedly connected to the inner wall of the second bearing 16. The second bevel gear 15 can rotate. The second bevel gear 15 is fixedly connected to the second rotating shaft 14. The threaded rod 17 is rotated through the gear connection. The second bevel gear 15 meshes with the first bevel gear 13. The threaded rod 17 is fixedly connected to the second bevel gear 15, so that the entire support structure can move up and down. The threaded rod 17 is threadedly connected to the threaded sleeve 23. The threaded sleeve 23 is fixedly connected to the threaded sleeve 23, and the slider 19 moves up and down inside the slide groove 20. The inner wall of the protective cover 4 is provided with the slide groove 20, and the slider 19 is slidably connected to the slide groove 20. The slider 19 is fixedly connected to the support rod 7 to support the support plate 8. The support rod 7 is provided with a groove 22 inside.

[0017] The support base plate 1 has multiple through holes 9 for placing bolts 2. Bolts 2 are placed inside the through holes 9 to fix the support base plate 1. The support base plate 1 has multiple anti-slip pads 3 to prevent the bolts 2 from loosening, and the bolts 2 pass through the anti-slip pads 3. The top of the threaded rod 17 is fixedly connected to an upper baffle 21 to limit the upper limit of the movement of the support rod 7. The bottom of the threaded rod 17 is fixedly connected to a lower baffle 18 to limit the lower limit of the movement of the support rod 7. The lower baffle 18 is above the first bevel gear 13. A support plate 8 is fixedly connected above the support rod 7 to support the workpiece. The right end of the first rotating shaft 12 is provided with a rotating handle 6, and the rotating handle 6 is detachable. The protective cover 4 is provided with a transparent observation port 5 and a scale line 10 to accurately observe the movement height of the support rod 7. The scale line 10 is located next to the transparent observation port 5.

[0018] Working principle: First, the support base plate 1 is used to achieve overall fixation: Place the support base plate 1 on the foundation bearing surface, pass the bolts 2 through the through holes 9 on the support base plate 1 and through the anti-slip pad 3 at the bottom, and tighten the bolts 2 to firmly connect the support base plate 1 to the foundation surface. The anti-slip pad 3 increases the coefficient of friction to prevent the support from sliding horizontally under force, ensuring overall stability. Then, the operator holds the rotating handle 6 and turns it clockwise or counterclockwise. The rotating handle 6 drives the first rotating shaft 12 connected to it to rotate. The first rotating shaft 12 is stably supported by the first bearing 11 to ensure no radial displacement during rotation. The first rotating shaft 12 rotates to the left and right. The first bevel gear 13 at the end rotates synchronously with the shaft. Since the first bevel gear 13 is meshed with the second bevel gear 15, it drives the second bevel gear 15 and the second shaft 14 fixed thereto to rotate. This process changes the direction of power transmission through bevel gear meshing. When the second bevel gear 15 rotates, the threaded rod 17 fixed thereto rotates synchronously. The threaded sleeve 23 on the threaded rod 17 undergoes axial displacement due to the threaded connection. At the same time, the slider 19 on the threaded sleeve 23 is embedded in the groove 20 on the inner wall of the protective cover 4. The groove 20 restricts the slider 19 to slide only in the vertical direction. Therefore, the threaded sleeve 23 drives the slider 19 to slide along the groove 20. As the slider 19 moves up and down, it drives the support rod 7 to move up and down synchronously through the connecting structure, so that the height of the support plate 8 at the top of the support rod 7 can be adjusted. The support plate 8 is used to support the upper load of scaffold crossbars, formwork and other materials. During operation, the workers can intuitively read the position of the slider 19 or support rod 7 through the transparent observation port 5 on the protective cover 4 and the scale line 10 next to it, and accurately control the adjustment height of the support plate 8 to meet the elevation requirements of the construction.
