[0001] The utility model relates to the technical field of engineering accessories, in particular to a lifting platform base. Background Art
[0002] At present, electric construction lifting platforms are used in the construction industry for exterior wall decoration such as curtain walls, coatings, and masonry. They can also be used for other high-altitude operations, such as exterior wall renovation and curtain wall cleaning. In electric construction lifting platforms, the load acting on the platform and the overall deadweight of the electric construction lifting platform are borne by the base at the bottom. Therefore, whether the base has sufficient strength, rigidity, and stability will directly affect the operation and safety of the electric construction lifting platform. At the same time, whether the transfer of the electric construction lifting platform is convenient, fast, efficient, and labor-saving is also related to the structure of the base.
[0003] Some traditional bases fix the legs on the four corners of the base body. In this case, the legs cannot be adjusted, the distance from the leg action point to the center of the base is a fixed value, and the area enclosed by the line connecting the four action points is also a fixed value, which is not conducive to the anti-overturning ability of the electric construction lifting platform when the eccentricity of the vertical eccentric load is too large or the horizontal load is too large, and is not conducive to the stability of the electric construction lifting platform; some bases are equipped with adjustable length legs, which can adjust the distance from the leg action point to the center of the base, but can only be adjusted to the distance to the center of the base in one direction, and the legs cannot rotate, which will inevitably affect the installation and use of the base in limited space.
[0004] Some traditional bases are made of profiles assembled into a square frame and welded together. The square frame is placed on the ground to transfer the load. Although such a base has a simple structure and strong load-bearing capacity, it does not have parts such as outriggers, telescopic tubes, and flat-top universal wheels. This makes the electric construction lifting platform have poor anti-overturning ability, and it is also very inconvenient, time-consuming and labor-intensive to transfer. Utility Model Content
