Description

VR-based indoor hoisting method Technical Field The invention relates to the field of indoor special space hoisting construction, in particular to an indoor hoisting method based on VR. Background At present, in the field of indoor hoisting engineering, main stream hoisting implementation modes are mainly divided into two types, namely, one type is to rely on the existing building structure to carry out hoisting operation, specifically, the original bearing structure with enough bearing strength in a hoisting area is directly selected as a stress point for hanging various hoisting devices, and the other type is to build a temporary hoisting system, namely, an independent bearing frame is temporarily built on site, and the frame is used as a supporting foundation of the hoisting operation. However, in either of the above ways, the indoor hoisting operation faces significant common challenges: firstly, the indoor space has the characteristics of strong sealing performance and dense barriers (such as upright posts, pipelines and fire-fighting facilities), so that the activity space of the hoisting equipment is limited, and the operation flexibility is insufficient; Secondly, the accurate confirmation of the position of the hanging point is difficult, the bearing safety of the stressed structure is required to be checked repeatedly, and if the hanging point is improperly selected or the bearing of the structure is overrun, risks such as structural deformation, equipment overturning and the like are easily caused; Thirdly, aiming at special-shaped artistic modeling components, large-scale integrated components and the like, the three-dimensional space attitude is extremely difficult to accurately position, and the problems of assembly dislocation, attitude deviation and the like easily occur in the traditional construction mode; fourthly, under the indoor closed environment, the personnel operation safety protection, the equipment operation monitoring and the accident emergency response are all relatively limited, and the difficulty of the personnel and equipment safety guarantee is increased; fifthly, the construction flow is lack of overall optimization, and the problems of unsmooth process connection and high reworking rate exist, so that the construction efficiency is low, and the labor and equipment costs are high. Due to the existence of the problems, the prior art is difficult to meet the engineering requirements of indoor suspended ceiling construction under a dense obstacle environment and accurate hoisting of complex special-shaped components, and an indoor hoisting solution with accuracy, safety and high efficiency is needed. The prior China patent application CN120470671A discloses a construction quality control method and system for installing a cast-in-place beam steel bar truss floor carrier plate based on BIM and VR, which comprises the following steps of BIM three-dimensional modeling, construction scheme simulation, VR scene construction, 3D scanning and model comparison, unmanned aerial vehicle cruising monitoring, real-time interaction and collaborative management, wherein the whole process, visualization and interactive construction quality control system is constructed, so that constructors can intuitively and clearly know the details of the space position, the connection mode and the like of each component, the understanding difficulty is greatly reduced, the construction errors caused by drawing understanding deviation are effectively reduced, the scheme simulation optimization before the steel bar truss floor carrier plate construction is realized, the real-time dynamic monitoring in construction and the efficient collaborative management of all construction parties are realized, the construction quality risk is pre-judged in advance, the construction deviation is corrected in time, the accuracy and efficiency of the construction quality control are improved, the construction cost is reduced, the construction period is shortened, and the construction quality of the steel bar truss floor carrier plate is ensured to meet the high standard requirement. The technical scheme mentioned in the document is not used for optimizing equipment suitability aiming at indoor closed and obstacle-dense environments, monitoring equipment such as unmanned aerial vehicles and the like is lack of targeted collision avoidance and movable space adaptation design, the problem of space limitation is difficult to deal with, accurate confirmation of the positions of hanging points and related contents of structural bearing safety verification are not involved, potential risks of hanging point selection and bearing overrun cannot be solved, 3D scanning and model comparison are mentioned, special modeling, positioning path optimization or accurate positioning schemes are not designed aiming at three-dimensional space forms of special-shaped components, effective solving means are not used for solving the problem of
