Suspension type electric hoist applicable for material transfer through soil removal port in top-down method

Abstract

The invention relates to a suspension type electric hoist applicable for material transfer through a soil removal port in a top-down method. The electric hoist comprises an upper suspension beam madeof I-beams, a lower crane beam which is provided with a guide rail, a plurality of middle interconnecting members welded between the upper suspension beam and the lower crane beam, and a movable electric hoisting mechanism comprising an electric hoist body, a pulley and a lifting hook. The upper suspension beam is bridged on floors on the both sides of the soil removal port, and the lower crane beam is hung below the suspension beam; and the electric hoisting mechanism is arranged on the lower crane beam, moved right and left in a limited guide rail interval, and controlled to execute or hoistand move materials on the floor to the soil removal port, then penetrate and place the materials onto an operation layer below, or hoist the materials on the operation layer below to the floor, and then move the materials right and left onto a target stacking position according to the requirements. Material transfer between the floors is conducted conveniently, efficiently, quickly and safely, and the problem that no applicable hoisting machine is provided for material transfer between the floors in the top-down method is solved.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction facilities, in particular to a suspension-type electric hoist suitable for being installed on a soil intake in a reverse method for transferring materials between floors. Background technique [0002] The upside-down method is a new foundation pit construction technology that has come out in recent years and is suitable for the construction of underground multi-storey structures in high-rise buildings. Enclosure and foundation construction support structure, under the support of the horizontal support system and enclosure system in the pit, the construction of the closed basement structure is carried out from top to bottom. Because it can be constructed simultaneously with the superstructure of high-rise buildings without interfering with each other, it has the advantages of high efficiency, saving social resources, environmental protection and shortening the construction perio...

Problems solved by technology

At present, although the reverse construction method has demonstrated certain technical advantages and has been gradually promoted, it is still in its infancy and faces many new technical difficulties that need to be explored and solved

Especially in terms of supporting facilities, there is currently no lifting machine suitable for material transfer in a small underground space. Therefore, conventional tower cranes or truck cranes are generally used for ground construction. Due to their relatively large volume, it is difficult to obtain soil. Unimpeded, fast and safe material transfer between the positive and negative zero-floor site and the bottom working surface layer in a narrow space with limited opening size and floor height, so the resource utilization rate is very low, the material transfer efficiency is very low, The accumulation of materials on site is serious, resulting in a long construction period, high construction costs, and potential safety hazards. Therefore, from an economical point of view, it is not ideal

Therefore, the lack of suitable material lifting machinery has become a major difficulty in the popularization and application of the reverse method. Therefore, it is necessary to research and develop a new type of efficient, fast and safe transfer of materials between floors suitable for the special environment of the reverse method construction. lifting device
