Technical Field

The invention relates to the technical field of capital construction facilities, in particular to a suspended electric elevator which is suitable for being arranged on a soil taking opening of a reverse construction method and used for transferring materials between floors.

Background

The reverse construction method is a new foundation pit construction technology which is published in recent years and is suitable for the construction of underground multi-layer structures of high-rise buildings, and is characterized in that a floor system structure, beams, plates, columns and outer walls of a basement are used as foundation pit retaining and foundation construction supporting structures, and the construction of a covered and excavated closed basement structure is carried out from top to bottom under the support of a horizontal supporting system and a retaining system in a pit. Because the construction can be carried out simultaneously without mutual interference with the superstructure of the high-rise building, the construction method has the advantages of high efficiency, social resource saving, environmental protection, shortening of the construction period of the building and the like, and the application is increasingly popularized. The basement structure construction mainly comprises the steps of firstly, pouring a first floor on a clean foundation ground level, and arranging a first floor soil taking opening on the first floor; then, underground excavation of a first-layer floor space through the first-layer plate soil taking opening, pouring of a first-layer floor, and forming of a first-layer plate soil taking opening on the first-layer floor; then, underground two-layer space is dug through a first-layer plate soil taking opening, and an underground two-layer floor is poured; and performing construction as required, or continuing to dig the lower-layer space after arranging the soil taking opening, or taking the lower-layer space as the lowest-layer bottom plate of the underground building, and performing construction of basic facilities such as pile heads, elevator shafts and the like as required from bottom to top. During the construction, material transfer operations such as outward transportation of a large amount of excavated sandy soil, internal supply of construction materials, inter-transfer of materials among floors and the like need to be carried out in a narrow space defined by taking the soil taking port as a unique channel and the floor height, and the field operation difficulty is high. At present, although the reverse construction method shows a certain technical advantage and is gradually popularized, a plurality of new technical difficulties are yet to be explored and solved in the starting stage. Particularly, in the aspect of supporting facilities, at present, no lifting machine suitable for material transfer in a narrow space under the ground exists temporarily, so that the conventional ground construction is generally followed by using a conventional tower crane or truck crane for coping, and due to the large volume, smooth, unobstructed and rapid and safe material transfer operation between a positive and negative zero-layer site and a bottommost operation surface layer site is difficult to perform in a narrow space with limited soil taking opening size and limited layer height, so that the resource utilization rate is low, the material transfer efficiency is low, the field materials are seriously accumulated, the construction period is long, the construction cost is high, and potential safety hazards exist, so that the lifting machine is not ideal from the economic aspect. Therefore, lack of suitable material lifting machinery has become a big difficulty in popularization and application of the reverse construction method at present, so it is necessary to research and develop a novel lifting device for efficiently, quickly and safely transferring materials between floors in a special environment suitable for reverse construction method construction.
