DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0031] The present utility model provides an external hanging mobile scaffolding as shown in Figure 1 and Figure 2 which includes a positioning cross bar 1, a positioning vertical bar 2 and a scaffolding 3. An adjusting mechanism is arranged on the side surfaces of the positioning cross bar 1, the positioning vertical bar 2 and the scaffolding 3. The adjusting mechanism includes a first roller 12, a fixed bottom plate 21, a fixed top plate 22, a connecting plate 210 and a second roller 31. The fixed bottom plate 21 is fixedly connected to the lower end of the positioning vertical bar 2, the fixed top plate 22 is fixedly connected to the upper end of the positioning vertical bar 2, the connecting plate 210 is fixedly connected to the side surface of the positioning vertical bar 2, and a driving mechanism is arranged on the upper side of the fixed top plate 22. The driving mechanism includes a side support plate 24, a transmission shaft 25, a winding disc 26, a driving motor 27 and a lifting steel cable 28.

[0032] Among them, the driving mechanism drives the scaffolding 3 to slide up and down between two groups of positioning vertical bars 2 to adjust the height of the scaffolding 3. At the same time, during the construction process, through the sliding of multiple groups of first rollers 12 on the side surface of the positioning cross bar 1, the positioning vertical bar 2, the scaffolding 3 and the driving mechanism are adjusted left and right, improving the construction range of the scaffolding 3 and the construction efficiency.

[0033] Refer to Figures 2 to 4 , support blocks 13 are fixedly connected to the left and right ends of the fixed bottom plate 21, the fixed top plate 22 and the connecting plate 210. The lower end of the support block 13 is rotatably connected to the first roller 12. There are three groups of positioning cross bars 1, and first positioning grooves 11 are formed on the front and back surfaces of the three groups of positioning cross bars 1. The first roller 12 is slidably connected to the first positioning groove 11. A fixing plate 14 is fixedly connected to the lower surface of the positioning cross bar 1, a through hole is formed on the surface of the fixing plate 14, and a fixed anchor rod 15 is inserted into the inside of the through hole. Second positioning grooves 23 are formed on the front and back surfaces of the positioning vertical bar 2. The second roller 31 is slidably connected to the second positioning groove 23, and the second roller 31 is rotatably connected to the side wall of the scaffolding 3.

[0034] Specifically, when it is necessary to move the scaffolding 3 left and right, by pushing the positioning vertical bar 2, the first roller 12 slides left and right inside the first positioning groove 11, thereby driving the positioning vertical bar 2 to slide left and right on the side of the building, enabling the scaffolding 3 to move left and right, and thus adjusting the position of the scaffolding 3.

[0035] Refer to Figure 3 and Figure 5, there are two sets of side support plates 24. The two sets of side support plates 24 are respectively fixedly connected to the left and right ends of the upper surface of the fixed top plate 22. The two ends of the transmission shaft 25 are respectively rotatably connected to the two sets of side support plates 24. The driving motor 27 is fixedly installed on the right side of the fixed top plate 22. The output end of the driving motor 27 is fixedly connected to the right end of the transmission shaft 25. There are two sets of winding discs 26. The two sets of winding discs 26 are respectively fixedly connected to the two ends of the transmission shaft 25. There are four sets of lifting steel cables 28. The four sets of lifting steel cables 28 are respectively wound around the surfaces of the two sets of winding discs 26. Two sets of limiting grooves 29 are formed on the surface of the fixed top plate 22. The lower ends of the lifting steel cables 28 pass through the limiting grooves 29 and are fixedly connected to the upper side of the scaffold 3.

[0036] Meanwhile, when it is necessary to adjust the height of the scaffold 3, the output end of the driving motor 27 drives the transmission shaft 25 to rotate. The transmission shaft 25 drives the winding disc 26 to rotate. The winding disc 26 winds and unwinds the lifting steel cable 28. At this time, the lower end of the lifting steel cable 28 drives the scaffold 3 to rise and fall. At the same time, the second roller 31 slides inside the second positioning groove 23 to position the scaffold 3 and improve the stability of the scaffold 3.

[0037] The working principle of the present utility model: The driving mechanism drives the scaffold 3 to slide up and down inside the positioning vertical rod 2 to adjust the height of the scaffold 3. At the same time, the first roller 12 slides left and right inside the first positioning groove 11 to adjust the horizontal position of the scaffold 3, thereby increasing the construction range of the scaffold 3 and facilitating quickly adjusting the scaffold 3 to a designated position for construction.

[0038] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
