[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, an adjustable attached lifting scaffold includes a scaffold frame 1, which is composed of a plurality of parallel outer-row columns 101, an inner-row columns 102 and a plurality of walkway boards 103. Two guide rails 2 are symmetrically installed on the inner side of the scaffold frame 1, and a plurality of anti-falling mechanisms are evenly distributed outside the guide rails 2. The anti-falling mechanisms are installed on the wall to prevent the guide rails 2 and the scaffold frame 1 from falling. A lifting mechanism is added to the scaffold frame 1, and the lifting mechanism is used to lift the scaffold frame 1 as a whole. A plurality of anti-falling rods 3 are evenly distributed from top to bottom on the side of the guide rail 2 close to the anti-falling mechanism.

[0024] In some disclosures, multiple outer row columns 101 and multiple inner row columns 102 are parallel to each other and spaced apart, multiple walkway boards 103 are distributed from top to bottom between the multiple outer row columns 101 and the inner row columns 102 to form a scaffolding frame 1, the multiple outer row columns 101 and the multiple inner row columns 102 are both assembled by splicing multiple poles with bolts, and multiple vertical diagonal braces and horizontal diagonal rods are evenly distributed between the multiple inner row columns 102 and the outer row columns 101 for reinforcement.

[0025] like Figure 3 and Figure 4As shown, the anti-fall mechanism includes a wall-mounted support 4, which is installed on the wall through wall bolts, and two guide wheels 5 are symmetrically rotatably installed on both sides of the front end of the wall-mounted support 4, and the guide wheels 5 are correspondingly slidably engaged on the guide rail 2, and a top supporter 6 is movably installed on the top of the front end of the wall-mounted support 4, and two tension springs 7 are installed between the top supporter 6 and the wall-mounted support 4, and the tension spring 7 is used to pull the top supporter 6 so that it is tilted and engaged with the anti-fall rod 3, and the top supporter 6 is tilted and engaged with the anti-fall rod 3 for anti-falling, and an anti-fall fork 8 is movably installed on the bottom of the front end of the wall-mounted support 4, and the anti-fall fork 8 is correspondingly movably engaged with the anti-fall rod 3 for secondary anti-falling;

[0026] When preventing falling: an anti-falling mechanism is provided, since the wall-attached supports 4 of multiple anti-falling mechanisms are installed on the wall through wall bolts, and the scaffolding frame 1 forms an up and down sliding movement between the guide rail 2 and the wall-attached supports 4, it is convenient for the subsequent overall lifting of the scaffolding frame 1, and under the action of the top support 6, it is normally inclined and engaged with the anti-falling rod 3 of the guide rail 2 for anti-falling support, avoiding the problem of falling of the scaffolding frame 1, and at the same time, under the action of the anti-falling fork 8, the scaffolding frame 1 has a secondary anti-falling effect, and at the same time, the anti-falling fork 8 and the top support 6 are movably connected with the wall-attached supports 4. Therefore, when the scaffolding frame 1 is lifted by relying on the wall-attached supports 4, the anti-falling rod 3 moves the anti-falling fork 8, and the top support 6 is separated from it without causing obstruction, avoiding the scaffolding frame 1 being blocked during lifting, and subsequently, under the action of the tension spring 7, the top support 6 is driven to reset and continue the anti-falling action.

[0027] like Figure 5 and Figure 6 As shown, the lifting mechanism includes an electric hoist 9 installed on both sides of the scaffold frame 1 through a bracket, a lower load-bearing frame 10 is symmetrically installed on both sides of the bottom of the scaffold frame 1, two rotating wheels 11 are installed side by side on the lower load-bearing frame 10, and an upper load-bearing frame 12 is installed on both sides of the top of the scaffold frame 1 and connected to the wall. A lifting steel rope 13 is fixedly installed on the upper load-bearing frame 12, and the lifting steel rope 13 passes around the rotating wheel 11 of the lower load-bearing frame 10, and the tail of the lifting steel rope 13 is connected to the hook of the electric hoist 9 for lifting;

[0028] Among them, during lifting: by providing a lifting mechanism, first, the upper load-bearing frame 12 is fixed on the wall, and the lower load-bearing frame 10 is fixed to the bottom of the scaffolding frame 1, and the lifting steel rope 13 is passed around the lower load-bearing frame 10 to connect with the electric hoist 9. Therefore, it is only necessary to start the electric hoist 9, and pull the lifting steel rope 13 through the electric hoist 9 to rise. Since one end of the pulling steel rope is fixed to the upper load-bearing frame 12, and the other end passes around the rotating wheel 11 of the lower load-bearing frame 10 and is connected to the electric hoist 9, the scaffolding frame 1 is pulled upward as a whole under the guidance of multiple wall-mounted supports 4 during the lifting of the electric hoist 9 to achieve lifting and climbing. There is no need to repeatedly erect the scaffolding frame 1, which reduces the workload of manual labor, runs safely and smoothly, accelerates the construction process, and shortens the construction period. After lifting, the upper load-bearing frame 12 and the lifting steel rope 13 can be removed.

[0029] The utility model provides an adjustable attached lifting scaffold, and the specific working principle is as follows: first, the scaffold frame 1 is spliced ​​to form a whole, and a protective net is added on the outside of the scaffold frame 1, and a flap and an inner extension plate are installed between the inside of the scaffold frame 1 and the wall for protection, so that the scaffold frame 1 obtains a safe construction space. Since two guide rails 2 are installed on the inside of the scaffold frame 1, and a plurality of anti-fall mechanisms are distributed from top to bottom on the corresponding wall, the scaffold frame 1 slides with the anti-fall mechanism through the guide rails 2, and the anti-fall mechanism can prevent the scaffold frame 1 from falling under normal conditions, thereby improving safety. With the cooperation of the lifting mechanism, the scaffold frame 1 can be lifted upward as a whole during operation to achieve climbing, without repeatedly setting up the scaffold frame 1, thereby reducing the workload of manual labor, running safely and stably, accelerating the construction process, and shortening the construction period.
