[0034] Working principle: When it is necessary to build a scaffold to install water conservancy and electromechanical equipment, the staff moves the pedals 18 in sequence, so that the pedals 18 drive the movable cylinders 7 on both sides to move to the designated installation position, and then the staff moves the carrying plate 1, so that the carrying plate 1 drives the extension plates 2 on both sides to move upward to the top of the support column 6. At the same time, the positioning cylinder 5 at the bottom of the extension plate 2 is inserted into the outer surface of the support column 6, thereby realizing the support positioning of the carrying plate 1, and then the staff rotates the handles 17 on both sides of the movable support cylinder 10 in sequence, so that the handles 17 drive the support cylinder 10 to rotate and move on the outer surface of the movable cylinder 7. At the same time, the support cylinder 10 drives the chassis 11 to move and contact the ground, so that the four support cylinders 10 and the chassis 11 are used in conjunction with each other to support the device. At the same time, its horizontal state is adjusted to realize the construction of the scaffold;

[0035] When it is necessary to adjust the bearing area of ​​the bearing plate 1 according to the actual installation environment, the staff rotates the movable limiting nut 4 in sequence, so that the limiting nut 4 is threadedly rotated on the outer surface of the stud 3 and moves away from the bearing plate 1, thereby releasing the limit of the bearing plate 1 and the extension plate 2. Then, the staff pulls the pedals 18 on both sides of the movement horizontally in sequence, so that the pedals 18 drive the movable cylinder 7, the support column 6, the positioning cylinder 5 and the extension plate 2 to move horizontally. When the extension plate 2 moves to the appropriate bearing length, the staff rotates the movable limiting nut 4 in the opposite direction in sequence, so that the limiting nut 4 is threadedly rotated in the opposite direction on the outer surface of the stud 3 and fits tightly with the connection between the bearing plate 1, thereby limiting the connection between the bearing plate 1 and the extension plate 2, and completing the adjustment of the bearing area of ​​the bearing plate 1;

[0036] When the height of the supporting plate 1 needs to be adjusted, the staff moves the supporting plate 1 upward, so that the supporting plate 1 drives the extension plate 2 and the positioning cylinder 5 to move upward and away from the supporting column 6, completing the disassembly of the supporting plate 1. Then, the staff rotates the movable limiting bolt 8 in sequence, so that the limiting bolt 8 moves out of the inner cavity of the pin hole 9, releasing the limit of the supporting column 6. Then, the staff moves the supporting column 6 upward in sequence, so that the supporting column 6 drives the pin hole 9 to move upward. When the supporting column 6 moves upward to the appropriate height, at the same time, the supporting column 6 drives the pin hole 9 to move to the position corresponding to the limiting bolt 8, the staff The staff rotates the movable limiting bolt 8 in reverse order so that the limiting bolt 8 is inserted into the inner cavity of the pin hole 9, thereby limiting the connection between the support column 6 and the movable cylinder 7. Then, the staff moves the supporting plate 1 again, so that the supporting plate 1 drives the extension plate 2 and the positioning cylinder 5 to move upward to the top of the support column 6, so that the positioning cylinder 5 at the bottom of the extension plate 2 is inserted into the outer surface of the support column 6, realizing the support and positioning of the supporting plate 1 and the extension plate 2, thereby completing the adjustment of the use height of the supporting plate 1.
