Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a mobile lifting platform applicable to civil engineering. Background Technique

[0002] The lifting platform is one of the relatively commonly used equipment in civil engineering and is an essential tool for construction workers to construct the top plate and wall surface. The stability of the existing lifting platform is poor. Due to the relatively complex construction site and the uneven ground, it is difficult for the lifting platform to maintain a horizontal state, posing a safety hazard of tipping over.

[0003] After retrieval, the existing published patent application number is: CN201922136391.0, and the published patent name is: A multifunctional lifting platform for civil engineering, belonging to the technical field of civil engineering construction. It includes a support platform, a lifting platform and a rotating platform. There are two first extension frames above the support platform; a rotating platform is provided on the upper surface of the lifting platform, a second extension frame is provided on the upper surface of the rotating platform, and a storage platform is provided at the top of the second extension frame. The utility model is provided with a first extension frame, which is controlled by a screw rod and a first moving seat, so that the lifting platform can move up and down. The second extension frame is provided so that the storage platform can be adjusted to any height position as needed; the utility model is provided with a rotating platform, and the rotating platform can be rotated through a rotating rod, so that construction workers can easily change their positions and directions during the work process, and the placement rack can rotate with the rotating platform. After the direction is adjusted, construction workers can also take the tools in the storage platform at any time.

[0004] However, when the above device is in use, the support block cannot move outwards. When the lifting platform rises, the center of gravity will also rise, which will cause the stability of the lifting platform to deteriorate, posing a risk of tipping over and insufficient support, and there is room for improvement.
