Due to the requirements of low condensation height and large height of the lifting operation platform, certain difficulties and contradictions exist in the technology.
However, the existing lifting mechanism used for the lifting platform is a scissor type, the structure of the scissor type lifting mechanism is a multi-layer lever hinge, the platform is arranged on the lever hinge frame, when a power source drives an oil pump to supply oil, pressure oil pushes a piston rod to extend out, so that one end of a lever is pushed, the lever hinge is relatively lifted, the platform is pushed to lift, but the higher the platform is lifted, the higher the supporting area of the lever hinge below the platform is, the supporting point of the lever hinge can be contracted, the gravity center of the platform can be deviated from the supporting point of the lever hinge, and therefore the stability and reliability of the. The other type is a mast type, the structure of the mast type is that different guide rails are mutually overlapped, a platform is fixed on the innermost guide rail, because two adjacent guide rails are in single-side contact, the guidance performance is poor, the bearing capacity of the platform is limited, and because the lifting mechanism of the mast type is complex, an oil cylinder and a chain mechanism are jointly born, the phenomena of chain clamping stagnation, oil cylinder instability and the like are easy to occur, the maintenance is inconvenient, the manufacturing and maintenance cost is high, particularly for a double-mast type or multi-double-mast type lifting platform, if all the oil cylinders cannot be synchronized, the lifting platform is inclined, and the damage of the construction lifting platform can be caused in serious cases. In addition, the guard rails of the scissor-type lifting platform are fixedly arranged on the periphery of the bearing platform, and when the elevator is folded, the elevator cannot be folded, so that the elevator needs a certain space height when entering different space doorways, and is inconvenient to transport and move; although the guard bar of the mast type lifting platform can be lifted by the oil cylinder, the guard bar can be lifted and lowered for several times, the procedure of fastening and fixing needs to be operated for many times, and the guard bar can be contracted and is troublesome and unsafe. The lifting platform of two kinds of modes above still has a common defect that constructor need follow the outside and turn over when carrying on article load-carrying platform and climb the guardrail and just can get into load-carrying platform, and is extremely inconvenient, lets constructor painstaking, and has certain potential safety hazard.
