Technical Field

[0001] The utility model relates to the technical field of lifting platform frame equipment, in particular to an automatic lifting platform frame. Background Art

[0002] Underground masonry walls are often used to construct support structures to reinforce laneways, tunnels or other underground spaces. These structures help prevent ground collapse and ensure the stability and safety of the underground working environment. Masonry walls can be used to construct structures such as ventilators and dustproof walls to improve ventilation conditions underground. Good ventilation is essential to reducing the accumulation of toxic gases underground and ensuring the safety of workers. Underground masonry walls are an important engineering measure in underground projects, designed to provide a stable working environment, ensure the safe progress of the project, and meet the requirements of structural support, ventilation, waterproofing, etc. required by the project.

[0003] However, the existing automatic lifting platform frame has the following problems: during the construction of underground ventilation facilities, after the wall is built to a height of 1.6m, steel pipes and fasteners are needed to build a working platform frame. However, in actual applications, this type of working platform has the disadvantages of poor mobility and non-adjustable height. During on-site use, it is necessary to lift and raise the frame twice, which is labor-intensive and time-consuming. Utility Model Content
