The middle parts of the two cross support branch tubes 76 are sleeved with positioning sleeves 75, and a cross support main pipe 71 is inserted between the two positioning sleeves 75. The top of the cross support main pipe 71 is clamped with a lifting hoist 72. In the present invention, when it is necessary to transport materials to the top of the scaffold, the bottom end of the ladder pedal mechanism 6 is removed, and a cargo transport space connected up and down can be constructed inside the scaffold through the installation groove 4. The lifting mechanism 7 built above can complete the material transportation operation inside the scaffold. Compared with the side transportation of the scaffold, it effectively avoids the outward shift of the center of gravity of the scaffold and the hidden dangers caused by the operator's body leaning out.

In the present invention, the step pedal mechanism 6 is based on The upper hanger 66 located above bears the main weight, and the bottom is inclined by the lower hanger 62. The pedal assembly 67 forms upper and lower steps between the supporting pipe frames 61. When the step pedal mechanism 6 is inclined, the pedal assembly 67 is distributed in a step-like manner to construct upper and lower steps between the two layers of the scaffolding. Both the upper hanger 66 and the lower hanger 62 can be inserted into the supporting pipe frame 61 for retraction. When the step pedal mechanism 6 is in a horizontal state, the pedal assembly 67 retracts the top to form a planar structure, filling the space of the installation slot 4 and forming a stable operating platform for the scaffolding. The two methods are simple and convenient to change.

[0028] As a further solution in the present invention, the pedal assembly 67 includes a multi-section limit cavity 672 arranged inside the support pipe frame 61, and a limit slider 673 is slidably installed in the limit cavity 672, and an L-shaped step pedal 671 is rotatably installed on the side of the limit slider 673, a positioning slide bar 674 is fixedly installed in the middle of the limit slider 673, and a push spring 675 is arranged between the limit slider 673 and the upper end of the limit cavity 672. In the present invention, when the support pipe frame 61 is tilted, the pedal assembly 67 relies on the restriction of the adjustment assembly 68, and the upper end of the L-shaped step pedal 671 is in a horizontal state. State, at the same time, under the action of the push spring 675, the limit slider 673 is located at the lower end of the limit cavity 672, bearing the weight of the step pedal 671. When the step pedal mechanism 6 is in a horizontal state, the adjustment component 68 pushes the upper end position of the step pedal 671 horizontally to change its position. The step pedal 671 moves the vertical surface to a horizontal position to form an assembly plate structure. The upper bracket 66 and the lower bracket 62 both push the positioning slide bar 674 inside the supporting pipe rack 61, so that the assembly plate formed by the step pedal 671 moves toward the middle, avoiding the formation of a cavity in the installation groove 4 that affects the safe operation of the scaffolding.

[0029] As a further solution in the present invention, the adjustment component 68 includes a fastening bracket 682 that slides with the support pipe frame 61, and a push-pull rod 685 that is rotatably connected to the side of the fastening bracket 682, and the middle part of the fastening bracket 682 is provided with a fan-shaped groove that slides with the push-pull rod 685, and the middle part of the push-pull rod 685 is screwed with a locking bolt 683 that cooperates with the fan-shaped groove. The adjustment component 68 also includes an adjustment rod 681 hinged to the end of the step pedal 671, and the end of the adjustment rod 681 is provided with an adjustment bolt 684, and the bottom of the push-pull rod 685 is provided with a rectangular slide groove that slides with the adjustment bolt 684.

When the adjustment rod 681 moves upward, it pulls the step pedals 671 to form a step structure distributed up and down. When the step pedal mechanism 6 needs to be used horizontally, the adjustment rod 681 moves downward to push the step pedal 671 to rotate, so that the vertical section of the step pedal 671 is flipped to the horizontal section. After that, the push-pull rod 685 is locked, and the fastening bracket 682 and the support pipe frame 61 are loosened, so that the adjustment assembly 68 slides with the pedal assembly 67, which is convenient for the retraction operation of the upper hanging bracket 66 and the lower hanging bracket 62.

By relying on the staggered inner installation tubes 11, an inclined step pedal mechanism 6 is built, and the step pedal mechanism 6 is used to construct a staircase connecting the two working platforms. Users do not need to climb from the side, and the center of gravity of the scaffolding is always placed within the range of the scaffolding base 2, which effectively prevents the scaffolding from tipping over. Each working platform is connected by the step pedal mechanism 6, and users can transport materials up and down through the step pedal mechanism 6.
