Background Technology
[0002] A construction hoist is a lifting device used for the vertical transportation of personnel and materials in high-rise building construction. It mainly consists of a ladder column composed of multiple standard sections connected to a certain height by bolts, and a cage that moves up and down on the ladder column. As the height of high-rise building construction increases, it is necessary to add standard sections to increase the height of the ladder column, and to connect the standard sections to the building walls with attachment rods to improve the safety of the ladder column. The standard sections are connected by bolts. The load of the cage is transferred to the building walls through the ladder column and attachment rods. The ladder column is the main load-bearing component of the cage, and the connecting bolts between the standard sections and the attachment rods between the standard sections and the building frame structure all bear the load. During construction, problems such as loosening or missing connecting bolts between standard sections and cracks in the building walls connected to the attachment rods are frequently encountered, affecting the safe use of the construction hoist and, in severe cases, causing safety accidents. To improve the safe use of construction hoists, the field requires operators to conduct regular manual inspections of the walls connected to the standard sections of the construction hoist by checking for loose connections, missing parts, wall cracks, and other safety hazards. However, due to the large number of connecting bolts and attachment rods, there are issues of omissions or oversights during manual inspections, which cannot effectively guarantee the safe operation of the construction hoist.
