When used, the main body is first constructed to the top floor of the building, and then the exterior wall decoration work is carried out from top to bottom; the platform body of the guide frame climbing work platform is a single-layer walkway plate structure. The drive unit drives the platform body to rise and fall along the standard section of the guide rail frame. It has a simple structure and does not require disassembly and assembly, but the carrying capacity is limited. It is mainly used in decoration or renovation construction. The exterior wall decoration work of some construction units will follow the main construction work.

[0004] Attached lifting scaffolds, floor-standing scaffolds, cantilever scaffolds, and electric hanging baskets all have the problems of high labor costs, high project costs, and long installation periods. When dismantling operations are carried out after the construction is completed, there are major safety hazards of high-altitude operations, and buildings with steel structures such as industrial plants cannot meet the requirements of main construction and decoration construction at the same time. Electric hanging baskets are not suitable for buildings with large overhangs on the top of the main structure and for buildings that are first dismantled and then installed during the renovation of old buildings. The guide frame climbing work platform cannot be used for main construction due to its own structural limitations. Utility Model Content

[0041] The platform body includes a load-bearing platform 100 and a protective frame 200. The load-bearing platform 100 includes a plurality of load-bearing units 110. The plurality of load-bearing units 110 are arranged along an extension direction perpendicular to the standard section of the guide rail frame. Each load-bearing unit 110 is a frame structure, and adjacent load-bearing units 110 are connected to each other. A driving unit 120 is arranged on the load-bearing platform 100 for correspondingly connecting to the standard section 300 of the guide rail frame.

[0042] The protection frame 200 is connected to the upper part of the carrying platform 100 , and a standard section holding device 240 for correspondingly connecting to the guide rail frame standard section 300 is provided on the protection frame 200 .

[0043] Among them, adjacent bearing units 110 can be directly connected to each other, or can be connected to each other through a connecting frame. Exemplarily, each guide rail frame standard section 300 can be inserted between two bearing units 110, and a connecting frame is set on the side of the guide rail frame standard section 300 away from the building structure, and the two bearing units 110 corresponding to each guide rail frame standard section 300 are connected by a connecting frame, and other two adjacent bearing units 110 are directly connected through a pin shaft. One or more specifications and sizes of bearing units 110 can be selected and combined to form a bearing platform 100, and a connecting frame is used to connect them to each other at the corner position of the building structure. They are combined according to different shapes of the building facade to meet various construction requirements and are suitable for complex building structures.

[0044] According to the actual building shape and structure, the number of guide rail frame standard sections 300 and driving units 120 is increased to achieve a suitable overall span of the bearing platform 100, and the span of the bearing platform 100 is 3m to 40m.
