Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of engineering construction, and particularly relates to a full-automatic construction lifting platform system for climbing and supporting. BACKGROUND

[0002] In the construction of super high-rise buildings and silo structures, the traditional construction lifting platform mostly adopts hydraulic jacking or steel wire rope traction technology, which has the following limitations:

[0003] The platform is driven by a hydraulic cylinder to be jacked in sections, relying on an external hydraulic pump station and a complex pipeline system. Disadvantages: the hydraulic system is prone to oil leakage, has high maintenance cost, and has poor stability affected by temperature; manual intervention is required for positioning during the jacking process, which is low in efficiency (about 1-2 hours for each jacking); the carrying capacity is limited (generally ≤50 tons), which cannot meet the construction requirements of large-span silo structures. Screw lifting system (such as a certain model SC200 / 200 construction elevator): the screw is driven to rotate by a motor, which drives the platform to ascend and descend along the guide rail. Disadvantages: the sliding friction between the screw and the nut causes serious wear, and the transmission efficiency is only 60%-70%; there is no dynamic anti-falling mechanism, and only mechanical brake is relied on, which has slow response speed (≥0.5 seconds); the platform structure is not modular, which is difficult to disassemble and cannot meet the requirements of rapid site transfer construction. The traditional corbel supporting technology realizes temporary support by manually inserting the corbel into the reserved hole of the building structure. The corbel needs to be manually extended and retracted, which has high-altitude operation risk; the support switching takes a long time (about 30 minutes for each switching), which affects the continuity of construction; the positioning accuracy of the corbel is poor (error ≥5mm), which easily causes stress concentration of the structure.

[0004] The above technologies generally have low automation degree, insufficient safety, and limited efficiency, which cannot meet the core requirements of modern super high-rise buildings for efficient, precise and full-automatic construction platforms. SUMMARY
