Problems solved by technology
However, the setting of the suspension mechanism also has certain limitations in practical applications, mainly in bridges, TV towers and other structures where the setting of lifting points is limited.
Especially in the maintenance and maintenance of bridges, due to the characteristics of large span and few lifting points in construction operations, the stiffness of the designed high-altitude operation platform cannot meet the requirements, thus limiting the application of high-altitude operation platforms to large-span construction applications. Therefore, a new type of high-altitude operation platform based on the cable structure is designed to solve practical engineering application problems

Embodiment Construction
[0015] Such as figure 2 A single lifting point platform will be composed of hoist 2, hoist mounting frame 3, platform standard section 7, end guardrail with outrigger 1, reinforced cable 5, fixed pin 9 of reinforced cable 5, and cable tensioner 10. Connect two single lifting point platforms to form a double lifting point cable-type high-altitude operation platform, such as figure 1 shown. The multi-lift point platform uses a plurality of oblique reinforcement cables 5 to pass through the hoist installation frame 3 to tension the two adjacent standard sections symmetrically, and the preload of the reinforcement cables 5 can be adjusted by the cable tensioner to meet the design requirements.
[0016] figure 2 In the structure, both sides of the hoist installation frame 3 have a vertical bar 8 structure connected with the end of the platform standard section 7 by bolts, and the vertical bar is equipped with a mounting bar 4 for installing a strengthening cable 5, and there i...

The invention discloses a guy cable type high-altitude working platform, which comprises a plurality of groups of single-lift-point platforms consisting of lifting machines, lifting machine mounting frames, platform standard joints, end part guard rails with supporting legs, reinforcing guy cables, fixing pins of reinforcing guy cables and cable tensioners, wherein the platform standard joints are symmetrically tensioned by penetrating a plurality of reinforcing guy cables through the lifting machine mounting frames in the single-lift-point platforms; pre-tightening force of the guy cables can be adjusted through the cable tensioners; and the groups of single-lift-point platforms are connected through bolts to form the guy cable type high-altitude working platform. According to the invention, by rationally arranging the positions of the lifting machine mounting frames and by using a stay cable structure, the dead weight of the structure is reduced, the rigidity of the platform is effectively improved, and the deformation of the platform in work is reduced in the design of the construction platform with limited number of suspension lift points; meanwhile, the platform has the characteristics of convenience in disassembly, assembly and transportation; and the requirements of construction equipment with limited large-span lifting points.
Description
technical field [0001] The invention relates to a cable-type high-altitude operation platform in the field of construction technology, in particular to a cable-type high-altitude operation platform for high-altitude construction operations with limited lifting points and long horizontal construction work surface. Background technique [0002] With the continuous development of construction mechanized equipment, a variety of construction solutions are provided for the construction, maintenance and maintenance of large and complex landmark building structures. The traditional method of high-altitude construction operations with high energy consumption, high pollution and high degree of danger is gradually replaced by efficient, safe and environmentally friendly high-altitude operation platforms based on wire rope suspension. The platform adopts the climbing hoist to climb the wire rope hanging from the suspension mechanism to complete the work. The suspension mechanism main...
