It can provide a safe operating place for construction workers. It is also used to place building materials and tools, so that construction workers can carry out wall construction, painting, installation and other operations at different heights and positions.

[0003] In the prior art, engineering scaffolding is generally composed of uprights, cross bars, scaffolding boards, scissor braces and wall connecting parts.

Clamp 1 801 and clamp 2 802 are sleeved at a predetermined position on the rod frame 201 and fixed by bolts. Since the spacing and height between clamp 1 801 and clamp 2 802 can be changed, the inclination angle of support rod 803 can also be changed, which is convenient for adjusting to the best anti-tilt position. Since the bottom of support rod 803 is in contact with the ground, the center of gravity of the present invention will be lowered, thereby improving the anti-seismic and anti-tilt performance; Working principle of the reinforcement frame 9: When installing the reinforcement frame 9, the two reinforcement pieces 901 can be directly rotated relative to each other, and the two reinforcement pieces 901 automatically cross each other.

[0043] Implementation method: The present invention provides an engineering scaffold with a feeding function. When using the present invention: Before construction, the present invention is moved to a predetermined position by the support member 10 and propped up. When the present invention encounters an unexpected situation, the support member 10 can be used to ensure that the present invention maintains a horizontal state. During assembly, the folding frame 2 is manually lifted, and the lifting mechanism 4 is started to move the limit frame 3 upward. After the limit frame 3 moves up to the right position, the limit frame 3 is fixed to the top of the folding frame 2 by the limit mechanism 7. Then, the anti-tilt shock-absorbing frame 8 is installed on the folding frame 2, and the reinforcement frame 9 is installed. When the working plate 5 is lifted by the lifting mechanism 4, personnel and materials can be transported. When materials need to be transported from the ground to the working plate 5, the movable plate 609 can be moved down to the ground to place the materials and moved up, and then the movable plate 609 is clamped and fixed by the clamping mechanism 14.

[0044] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
