Embodiment Construction

[0022] Figure 1-3 As shown, a large-scale lifting device based on deep foundation pit vertical soil movement includes a power system composed of an electric motor and a hydraulic motor 17, and is characterized in that it also includes a car system, an oil cylinder system, a support column system, a protection system and an intelligent Control system, the car system is connected above the oil cylinder system, and is driven by the oil cylinder system to move vertically up and down; the oil cylinder system is located above the supporting column system, and the protection system is located outside the car system, and the intelligent control system controls the oil cylinder system and the protection system linkage.

[0023] The car system is composed of car 1, car load-bearing frame 2, car track 3 and car roller 4. Roller 4 limits its horizontal position, only does vertical sliding.

[0024] The cylinder system includes a multi-stage relay cylinder, a cylinder beam 8, a cylinder...

Abstract

The invention discloses a large-scale lifting device based on deep foundation pit vertical earthmoving. The large-scale lifting device comprises a power system composed of an electric motor and a hydraulic motor, and is characterized by further comprising a cage system, an oil cylinder system, a support column system, a protective system and an intelligent control system, wherein the cage system is connected above the oil cylinder system and is driven by the same to be in vertical up-and-down movement, the oil cylinder system is positioned above the support column system, the protective system is arranged outside the cage system, and the intelligent control system is used for controlling linkage of the oil cylinder system with the protective system. The large-scale lifting device based on deep foundation pit vertical earthmoving can be used for deep foundation pits in various support forms, is small in occupied space, fast to mount and demount, capable of improving unearthing efficiency and shortening construction periods, reusable and cost-reducing.

Description

technical field [0001] The invention relates to the technical field of building engineering construction; in particular, it relates to a large-scale lifting device based on deep foundation pit for vertical soil movement. Background technique [0002] Today, with the development of the economy and the rapid development of cities, there are more and more high-rise and super high-rise buildings, and the number and depth of deep foundation pits are also increasing. Over-dense buildings and scarce land make the available surrounding space narrow, and excavation outside the pit cannot be carried out during large-scale excavation. At present, the earth and rock works of deep foundation pits are mainly excavated by soil ramps filled with original soil in the pit, and straight or circular steel temporary bridges. The earth slope filled with the original soil occupies a large area, the road condition is poor, and the danger is great. Especially for the foundation pit with internal su...
