Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0026] A multi-purpose construction scaffold, please refer to Figures 1 to 5In this embodiment of the invention, the lifting sleeve 27 is snapped onto the main fixed rod 21. After sliding the lifting sleeve 27 to the bottom of the main fixed rod 21, the main fixed rod 21 is erected, and then the support plate 29 is snapped between a group of main fixed rods 21. The group of main fixed rods 21 are assembled and connected together. The motor 217 is installed and fixed to the middle of the top of the support plate 29. The bevel gear rod 28 is snapped onto the top of the bevel gear 218 fixedly connected to the output end of the motor 217. Then, the motor 217 drives the lifting sleeve 27 to slide upward along the main fixed rod 21 until it reaches a position that the worker can stand and touch. The third fixed support rod 219, the second fixed support rod 211, and the first fixed support rod 210 are installed on the bottom of the inner side of the lifting sleeve 27. Then, the positioning sleeve 25 is installed and snapped onto the main fixed rod 21. The second fixed support rod 211, the first fixed support rod 210, and the third fixed support rod 219 are installed on the bottom of the main fixed rod 21. The bottom end of the support rod 219 is fitted with a clamp to the top of the inner side of the positioning sleeve 25. Then, the first fixed crossbar 213 is fixed to one end of the positioning sleeve 25. The arched pressure-bearing frame plate 212 is fixed to the top of the first fixed crossbar 213 and the bottom of the first fixed support rod 210 and the second fixed support rod 211. After installation and fixing, the motor 217 drives the lifting sleeve 27 to slide towards the top of the main fixed rod 21. When the clamp plate 29 drives the connecting pedal 31 to move up to the top of the main fixed rod 21, and drives the rotating plate connecting block 35 to lock onto the bottom of the limiting plate 37, the limiting plate 37 pushes the rotating plate connecting block 35 down, thereby driving the installation docking positioning plate 33 to slide out from the storage cavity 32 and lock onto the top of the docking clamp plate 227 for fixing. This facilitates the quick assembly and installation of scaffolding, the installation and fixing of fixed support rods at high positions on the scaffolding, and the installation and fixing of the pedals at the top of the scaffolding.

[0027] The specific process of installing the lifting sleeve 27 is as follows: After laying the main fixing rod 21 horizontally, the lifting sleeve 27 is fitted onto the outside of the main fixing rod 21. The lifting sleeve 27 is slid until it reaches the bottom of the outside of the main fixing rod 21. One end of the clamp plate 29 is then secured to the bottom of the inside of the lifting sleeve 27, and the other end is secured to the lifting sleeve 27 fitted onto the outside of another main fixing rod 21. One side of the second fixing crossbar 222 is welded to the bottom of one side of the lifting sleeve 27, and the other side of the second fixing crossbar 222 is welded to the lifting sleeve 27 fitted onto the outside of another main fixing rod 21. This allows the four main fixing rods 21 to be assembled together under the action of the four lifting sleeves 27, the second fixing crossbar 222, and the clamp plate 29. The motor 217 is then started, which drives the bevel gear 218 fixedly connected to the output end to rotate. The rotating bevel gear 218 drives the bevel gear rod 28 meshing at the top to rotate. Under the action of the double-headed gear rod meshing at the middle of one side, the rotating bevel gear rod 28 drives the four drive gear rings 216 meshing at both ends of a set of bevel gear rods 28 to rotate synchronously. The rotating drive gear rings 216 drive the lifting gear 214 meshing at the bottom end of the arrow gear rod 215 through the arrow gear rod 215 meshing at the bottom end to rotate. The rotating lifting gear 214 slowly moves upward along the lifting tooth groove 22. When the lifting gear 214 moves upward along the lifting tooth groove 22, it drives the lifting gear The lifting sleeve 27, rotatably connected to the outer side of the 214, moves upward along the outer side of the main fixed rod 21. When the lifting sleeve 27 moves to a height that the operator can reach with their hand, the operator manually fixes the top ends of the second fixed support rod 211 and the third fixed support rod 219 to the bottom end of the inner side of the lifting sleeve 27 fitted on the main fixed rod 21. The top end of the first fixed support rod 210 is fixed to the bottom end of the inner side of the lifting sleeve 27 fitted on the other main fixed rod 21. Then, the operator manually snaps the positioning sleeve 25 onto the bottom end of the outer side of the main fixed rod 21, fixing the joint so that the positioning sleeve 25 can fit onto the outer side of the main fixed rod 21. Then, the first fixed crossbar 213 is welded to the installed set of positioning sleeves 25. The first fixed support rod 214... The bottom end of the first fixed support rod 210 is fixed to the positioning sleeve 25 located at the bottom of the first fixed support rod 210 at a relative position on the top. The bottom end of the second fixed support rod 211 is installed and fixed to the positioning sleeve 25 located at the bottom of the second fixed support rod 211 at a relative position on the top. Then, the arched bearing frame plate 212 is clamped to the top of the first fixed crossbar 213. The two ends of the top of the arched bearing frame plate 212 are successively fixed to the bottom of the second fixed support rod 211 and the bottom of the first fixed support rod 210. Then, a second fixed crossbar 222 is welded to the middle of one side of the positioning sleeve 25. The other main fixed rod 21 assembled on the other side of the main fixed rod 21 is spliced ​​together by the second fixed crossbar 222. X-braces 225 are welded to the upper and lower ends of the second fixed crossbar 222.Climbing rods 224 are welded to the bottom or top of the X-bracing 225. A connecting rod 223 is welded to one end of the climbing rod 224 and the second fixed crossbar 222. Multiple climbing rods 224 are assembled together to form a ladder. Then, the lifting sleeve 27 continues to slide upwards along the main fixed bar 21, thereby driving the positioning sleeve 25, which is fixedly connected to the bottom of the connecting rod 26, to slide upwards. This causes the assembled parts to slide upwards. When the bottom of the positioning sleeve 25 rises to a position where workers can reach it, the same parts of the scaffolding are repeatedly assembled. After assembly, an arched support block 221 is welded to the bottom of the welded ladder. This facilitates rapid assembly and installation of the scaffolding and allows for the installation and fixation of fixed supports at higher points on the scaffolding.

[0028] When the lifting slide 27 rises to a position within reach of the worker, the connecting pedal 31 is engaged with the docking clamp plate 227 fixedly connected to the top of the third fixed crossbar 226. When the connecting pedal 31, driven by the upward movement of the lifting slide 27, has rotating plate connecting blocks 35 at both ends contacting the bottom of the limiting plate 37, the continuing upward movement of the lifting slide 27 will push the rotating plate connecting blocks 35 against the limiting plate 37. The limiting plate 37 will then push the unfixed rotating plate connecting blocks 35 towards the inside of the receiving cavity 32. The downward movement of the rotating plate connecting blocks 35 will push the bottom rotating extension push plate 36, under the action of the positioning rotating plate 34 already positioned on the other side of the rotating plate connecting block 35, to slide outwards from the receiving cavity 32, thereby pushing one side of the extension push plate 36... The rotating mounting and positioning plate 33 slides outward from the storage cavity 32. When the top of the rotating plate connecting block 35 is parallel to the top of the storage cavity 32, one end of the mounting and positioning plate 33 slides into the storage cavity 32 and engages with the top of the docking clamp plate 227. Then, the lifting sleeve 27 slides down, causing the top fixed connecting pedal 31 to slide down synchronously. This allows the bottom of the mounting and positioning plate 33, which extends and opens on both sides of the connecting pedal 31, to engage with the top surface of the docking clamp plate 227. This allows the slot at the bottom of the mounting and positioning plate 33 to engage with the slot at the top of the docking clamp plate 227, thus assembling one end of the mounting and positioning plate 33 with the docking clamp plate 227. This facilitates the installation and fixing of the pedal at the top of the scaffold.

[0029] After the scaffolding is assembled, rotate the screw 220. The screw 220 drives the adjusting gear 23, which is engaged on one side, to rotate. The rotating adjusting gear 23 will cause the positioning block 24, which is engaged on the outside, to slide outwards towards the main fixed rod 21. This allows the multiple positioning blocks 24, which are engaged on the outside of the adjusting gear 23, to sequentially engage with the lifting sleeve 27 and the positioning sleeve 25, fixing the lifting sleeve 27 and the positioning sleeve 25 to the main fixed rod 21. This prevents the adjusted positions of the lifting sleeve 27 and the positioning sleeve 25 from changing under external pressure, and facilitates quick positioning and fixing of the nodes of the installed scaffolding.

[0030] When a worker steps on the top of the connecting pedal 31, the pressure generated is dispersed by the corner frame formed by the first fixed support rod 210 and the second fixed support rod 211 and the arched frame of the arched pressure-bearing frame plate 212, thereby increasing the overall pressure resistance of the device. At the same time, when the device is under pressure, the X-shaped frame formed by the first fixed support rod 210 and the second fixed support rod 211 helps to fix the overall scaffolding, which is beneficial to prevent the scaffolding from deforming under pressure.

[0031] After the scaffolding is assembled, workers can climb to the top of the connecting step 31 using the ladder composed of climbing pole 224, third fixed horizontal bar 226, connecting vertical bar 223 and X-bracing 225. At the same time, workers can also use the ladder to weld the third fixed horizontal bar 226 and the connecting clamp plate 227. When the ladder is under pressure, multiple X-bracing 225s fix the ladder in shape, which helps to prevent the ladder from deforming when it is compressed. Meanwhile, the arched support block 221 disperses the pressure on the ladder.

[0032] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
