Existing circular operating platforms are mostly combinations of fixed-size trusses and platforms, which have the following main drawbacks: the platform radius is fixed, making it unsuitable for grain silos of different diameters or for construction of sections with varying wall diameters, resulting in poor versatility.

[0026] In order to address the above-mentioned deficiencies, this application provides a ring-shaped operating platform (hereinafter referred to as "ring-shaped operating platform") for slipform construction of grain silos, which is mainly used in slipform construction operations of grain silos.

[0027] See Figure 1 and Figure 2 The circular operating platform mainly includes a circular main frame 1, which is arranged on the grain silo slipform. Several telescopic beams are evenly distributed around the circumference, and several fan-shaped footboards are laid on the telescopic beams. In use, all telescopic beams can be extended or shortened simultaneously to adapt to the construction of grain silos of different diameters and variable-diameter sections of the silo wall, thus enhancing its versatility.

[0028] In some embodiments, the annular main frame 1 is composed of multiple arc-shaped main beams 2 spliced ​​together, which facilitates disassembly and assembly.

[0038] In some embodiments, a slip plate 7 is provided on the pedal, and the slip plate 7 is fan-shaped (e.g., ...). Figure 1 As shown in the illustration, all fan shapes mentioned in this application refer to fan-shaped annular shapes. A foot guard 8 is provided between the edge of the anti-slip plate 7 and the annular main frame 1.

[0040] In some embodiments, the ring-shaped operating platform further includes a guardrail 9, which is arranged around the outer ring of several telescopic beams.

[0041] Furthermore, a safety net is provided at the bottom of the guardrail 9. Preferably, the height of the guardrail 9 is not less than 1.2m, and a portable assembly guardrail can be adopted, which is a quick-assembly and disassembly structure.

[0042] The workflow of the ring-shaped operating platform for slipform construction of grain silos provided in the above preferred embodiment is as follows: S1. Assembly: Adjust the extension length of the telescopic beam according to the diameter of the grain silo and lock it; splice several arc-shaped main beams 2 to form a ring main frame 1, and fix it to the lifting frame through the sliding mold connecting seat 10.
