Description

Technical Field

[0001] The invention relates to the technical field of hoisting system equipment, in particular to a hoisting system suitable for special-shaped domes. Background Art

[0002] Traditional construction of special-shaped domes often relies on tower cranes, hoists, or full-height scaffolding, which poses significant challenges such as large space requirements, high costs, and heightened safety risks. This is particularly true in urban centers, where large equipment cannot be brought in. Furthermore, special-shaped domes have large spans and numerous installation surfaces (for example, the MixC project in Tongzhou, Beijing, spans 1,945 square meters and features 1,073 special-shaped panels), making traditional methods inefficient. While attempts have been made domestically and internationally to improve hoisting equipment, these efforts continue to face challenges such as structural limitations, high costs, and poor coordination. It is necessary to solve the problems of large space occupation, high equipment cost, low lifting efficiency and high safety risks in the construction of special-shaped domes, realize multi-angle collaborative lifting, and adapt to the limitations of complex building structures.

[0011] Specifically, two tower structures and two cable rail support structures are provided to carry out the hoisting of the glass at both sides of the dome frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Multi-angle cableway system: A triangular cone-shaped tower (100×100×5mm square tube column, 1200mm pitch) is welded to the top of the dome. 16mm diameter steel cables are connected to the building structure at multiple points to form a load-bearing cableway. A winch (3t) and electric hoist are used to achieve multi-angle lifting. Mobile support cableway system: A movable bottom support frame (equipped with a 1500kg counterweight and locking wheels) is set up, and the steel cables are connected to the dome tower to form a mobile cableway, covering the area without structural anchor points; Cable net springboard soft platform: 14mm steel wire rope is used to build a 2000×2000mm mesh cable net, and rock wool springboards are laid to form the working surface, matched with a double-layer anti-fall net (50×50 / 100×100mm aperture) and a life rope system.

[0013] When working together: The panels are transported to the installation floor by an off-site crane and precisely hoisted using a cableway system (fixed with electric suction cups and wind ropes to prevent sway). The operation area is divided into 30° intervals, and multiple ropeways operate synchronously; The soft platform is dynamically adjusted as the installation progresses, and the springboard is gradually removed as the panels are laid.

[0014] Product Structure The lifting system consists of three core modules: Multi-angle cableway module: It includes a triangular cone-shaped tower (100×100×5mm square tube column, four-step cross brace with a pitch of 1200mm) welded to the top of the dome, a 16mm diameter load-bearing steel cable and a 3-ton winch unit. The tower forms a 30° radial cableway with the building structure through the steel cable. A fixed pulley block is installed on the top and an electric hoist (including a 200kg suction cup sling) is connected to the end to achieve multi-angle synchronous lifting.

[0015] Mobile support cableway module: It consists of a bottom adjustable support frame (with a 1500kg counterweight and locking rollers), a 7m high tower and a telescopic cable track. The bottom frame connects the vertical frame and the inclined cable through a pin shaft to achieve stepless adjustment of the cableway angle from 0 to 45°, adapting to complex working conditions where there is no fixed anchor point on the edge of the special-shaped dome.

[0016] Cable net soft working platform: 14mm steel wire rope is used to construct a 2000×2000mm grid bottom protective net, covered with a double-layer anti-fall net (50×50mm upper interception + 100×100mm lower buffer), and the surface is paved with anti-slip rock wool springboards (25mm high anti-slip strips are added when the inclination is ≥10°) to form a detachable three-dimensional working surface.

[0017] Three modules work in tandem: the tower serves as a high-altitude fulcrum, the cables form a three-dimensional lifting channel, and the soft platform provides a safe working surface. This modular design enables rapid assembly and disassembly (with a 95% reuse rate for the tower and cables), covers 98% of all irregular dome work surfaces, reduces the lifting height from the traditional 41m to 5-7m, and achieves a single cableway lifting speed of 1.5 blocks per hour.

[0018] Safe and efficient: The soft platform anti-fall system + life rope dual protection reduces the lifting height to 5-7m (traditional crane lifting height is 41m), and the installation accuracy is improved by 40%; Space saving: Eliminate full racks (originally 18,000m 3 Space), outdoor only requires hardened road surface for lifting, and indoor vacancy rate is increased by 80%; Cost optimization: The material reuse rate reached 95% (steel pipes and wire ropes were used for subsequent construction), saving 917,000 yuan in measures costs for a single project (Beijing project data); Strong adaptability: covers 98% of special-shaped dome working surfaces, with a lifting speed of 50 blocks / day (traditional method ≤ 20 blocks / day), especially suitable for height-restricted areas in urban centers.
