Walking small electric hoister suitable for transferring materials between reverse building method floors

Abstract

The invention relates to a walking small electric hoister suitable for transferring materials between reverse building method floors. The electric hoister comprises front and back column frames containing bottom interconnecting beams, upper cross beams, left and right bracing stand columns and left and right side and middle assembly nodes, a bottom bracket module containing a counter-force bracketsystem, an anti-tilting truss containing upper and lower frame rods, bracing rods and vertical rods, a crane cross beam consisting of a material extracting section and a suspension section, a counter-force anti-tilting mechanism containing a bracket, disc buckles and upper and lower support legs, and a walking lifting mechanism containing an electric hoister, pulleys and lifting hooks. A hoistermain body is fixedly limited between a floor and a ceiling near a soil taking port with a bottom bracket module as a ground support and with four upper top support plates as top supports; materials can smoothly walk on guide rails as needed, and are quickly, efficiently and safely transferred from top to bottom or from bottom to top; and the electric hoister is simple, reasonable and practical instructure, and solves the difficulty of shortage of proper material hoisting machinery in traditional reverse building method construction.

Description

technical field [0001] The invention relates to the technical field of infrastructure construction facilities, in particular to a walking type that is suitable for transferring materials between floors in reverse construction, helps to improve transfer efficiency, relieves the use pressure of the positive and negative zero-floor sites, and ensures construction safety and management. Small electric hoist. 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 ea...

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. In the narrow space with limited opening size and floor height, unobstructed, fast and safe material transfer operations are carried out between the positive and negative zero-floor sites and the bottom working surface layer site, so the resource utilization rate is very low, the transfer efficiency is very low, and the on-site The accumulation of materials is serious, resulting in a long construction period, high construction costs, and hidden safety hazards. Therefore, from an economic 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 small machine that is suitable for efficient, fast and safe transfer of materials between floors in the special environment of reverse method construction. lifting device
