Description

Technical Field

[0001] This invention belongs to the technical field of special equipment for high-altitude construction operations, lifting and hoisting machinery, curtain wall maintenance equipment, exterior wall cleaning equipment, and high-altitude fire fighting equipment. Specifically, it relates to a modular high-altitude operation device developed by an enterprise for use on the exterior facades of various buildings. It relies on a double-sided wall-mounted load-bearing carrier to lay steel wire ropes to form a flexible walking track, and cooperates with a horizontally sliding main unit to achieve integrated left and right movement and vertical lifting and hoisting of the exterior facade. Background Technology

[0002] Currently, high-altitude operations on the exterior facades of residential buildings, commercial buildings, and industrial plants generally employ traditional equipment such as fixed suspended baskets, single-point winch cranes, attached climbing scaffolds, and fixed aerial work platforms. Existing equipment suffers from common technical shortcomings in the industry: traditional equipment is mostly single-point fixed and can only be lifted vertically at a fixed point, unable to achieve large-scale continuous lateral movement along the building facade, limiting the operational coverage area and resulting in poor versatility for different building spans and facade structures; existing equipment has limited functions and is mostly a specialized structure, only suitable for exterior wall cleaning or curtain wall installation, unable to be modularly compatible with multiple high-altitude operation conditions, resulting in redundant investment of resources and poor versatility; conventional equipment relies on temporary ground supports or single-point wall attachment, resulting in poor overall stress balance, weak wind resistance, cumbersome on-site disassembly and assembly procedures, and low equipment reusability; there is a significant industry gap in the field of high-altitude fire fighting on the facades of super high-rise buildings and commercial and industrial buildings, conventional fire ladders and fixed fire monitors have limited operating height and cannot accurately target and spray at any point on the facade, and there is a lack of mobile and fully mobile special emergency operation equipment for fires involving combustible materials on exterior walls and equipment outside windows. In the existing technology, there is no publicly available and mature application of an integrated operation architecture that integrates a load-bearing carrier on both sides of the building facade, a steel cable in the middle to form a flexible track, a traveling host that can slide laterally along the steel cable, and a vertical lifting and hoisting structure at the bottom. There is a significant technological gap in the industry, and there is an urgent need for new standardized and modular high-altitude operation equipment solutions. Summary of the Invention

[0003] 1. Purpose of the Invention: Addressing the industry pain points of existing high-altitude work equipment for building facades, such as limited lateral movement, limited functionality, weak versatility, and inconvenient installation and reuse, this company has developed a steel cable linkage high-altitude work system for building facades based on a double-sided load-bearing carrier. By deploying load-bearing carriers on both sides of the building facade and forming flexible walking tracks through steel cable bridging, coupled with a self-propelled lateral sliding main unit, it achieves full-area left-right movement on the wall surface, integrating vertical lifting and hoisting functions. Adopting a modular design for different application scenarios, it is compatible with various working conditions such as fire fighting, curtain wall installation and maintenance, exterior wall cleaning, high-altitude material and equipment hoisting, and industrial plant facade inspection. It features strong structural adaptability, stable stress, high safety redundancy, and can be disassembled and reused across projects, making it suitable for large-scale engineering applications. 2. Technical Solution: A double-sided load-bearing steel cable linkage high-altitude work system for building facades includes six core components: a double-sided end anchor support mechanism, a steel cable deployment component, a safety redundancy steel cable component, an integrated lateral sliding walking main unit, an integrated modular multi-functional work platform, and a safety redundancy protection component. Symmetrical double-end anchor point support mechanisms are arranged on both sides of the building facade, serving as the core anchoring and force-bearing fulcrums at both ends of the system, adaptable to various building installation structures and load conditions. The steel cable laying component laterally spans between the two anchor point mechanisms, serving as both a track and load-bearing function. The safety redundant steel cable component is layered, physically isolated, and independently stressed from the main steel cable, forming a double safety protection foundation. An integrated lateral sliding and traveling main unit slides on the main steel cable, integrating lateral travel and vertical lifting drive, enabling full-area lateral sliding and fixed-point stopping on the facade. The main unit and redundant steel cable establish a protective connection. A modular multi-functional work platform is hoisted below the main unit, integrating load-bearing, lifting, and multi-module rapid switching functions, capable of carrying personnel and materials, adaptable to various working conditions. The safety redundant protection components are independently deployed, constructing a multi-level fall protection architecture. 3. Beneficial Effects This invention has several significant advantages over existing technologies: First, it adopts a double-sided standardized anchor point support structure, which is adaptable to various building installation scenarios and has strong versatility. Secondly, it adopts a dual-cable independent layered layout structure to achieve dual safety redundancy protection, which greatly improves the safety of high-altitude operations; Third, it pioneered an integrated architecture of double-sided load-bearing carrier on the exterior facade, flexible steel cable track, horizontal sliding host, and vertical lifting, breaking through the technical bottleneck of traditional high-altitude equipment that can only operate at fixed points, and realizing full coverage operation on the exterior facade. Fourth, the machine features a modular design, allowing for quick replacement of operation modules such as fire jet, curtain wall cleaning, material hoisting tools, and maintenance fixtures, making it multi-purpose and reducing the cost of engineering equipment. Fifth, the horizontal sliding host and the multi-functional module are respectively connected to the safety redundancy steel cable to form an independent double cable double safety redundancy architecture, which effectively avoids the risks of high-altitude rope breakage, overload, and overspeed fall, and the protection level is far superior to traditional equipment. Sixth, the system architecture has a wide protection scope and strong resistance to plagiarism, modification, and circumvention. Seventh, the overall architecture is standardized and universal, not limited by building height or facade design, making it highly valuable for industrialization and industry promotion.

Detailed Implementation

[0005] The main body of the system of this invention consists of six core components: a double-sided end anchor support mechanism (1), a steel cable laying assembly (2), a safety redundancy steel cable assembly (3), an integrated lateral sliding walking host (4), a detachable and interchangeable functional operation module (5), and a safety redundancy protection assembly (6). Among them, the integrated lateral sliding walking host (4) is mounted to form a modular multi-functional operation platform. The detachable and interchangeable functional operation module (5) includes three subdivided end points: a manned high-altitude operation module, an exterior wall cleaning operation module (5a), and a high-altitude fire spraying operation module (5b). The double-sided end anchor support mechanism (1) is symmetrically fixed at the end position of the building facade, serving as the load-bearing anchor support point of the overall equipment. It can be flexibly selected and combined according to the building structure, installation space, load-bearing capacity, and wind pressure conditions. The two sets of steel cable structures are laid out in parallel layers, independently stressed, and do not interfere with each other. The steel cable laying assembly (2) is horizontally connected between the two side anchor mechanisms, serving as both a track and a load-bearing traction function. The integrated horizontal sliding walking host (4) is mounted on the main load-bearing steel cable and integrates the walking drive and vertical lifting drive structure. It can autonomously complete horizontal sliding and fixed-point docking. It can realize the vertical lifting of the modular multi-functional work platform by relying on the built-in drive structure. The upper part of the host is connected to the safety redundant steel cable assembly (3) for protection. Various work terminals can be hoisted under the integrated horizontal sliding walking host (4). According to the work requirements, one of the three interchangeable functional work modules (5) can be selected: the manned high-altitude work module, the exterior wall cleaning work module (5a), and the high-altitude fire spraying work module (5b). The figure only shows three preferred modules. The work terminals that can be adapted to this invention are not limited to the types shown in the figure. They can also quickly replace the curtain wall maintenance tool module, the high-altitude material hoisting tool module, and other various exterior facade work tools. They can be switched and used as needed, and are suitable for manned operations, fire emergency, curtain wall cleaning, material hoisting, exterior wall maintenance and other multi-scenario operations. Different work terminals are independently set up and directly replaced and installed to realize one machine for multiple scenarios. Equipped with an independent redundant protection component (6), the two ends are respectively connected to the safety redundant steel cable component (3) and the currently selected multi-functional operation module (5) to construct a multi-level fall protection architecture, further improving the operational safety of complex ultra-high-rise working conditions. The whole machine adopts integrated remote control, which has high flexibility in adapting to working conditions.
