[0021] The following non-limiting examples illustrate the present application.

[0022] Example 1

[0023] refer to Figures 1 to 3 As shown, reference Figures 1 to 3 As shown, a construction method of a shallow circular silo dome steel structure frame platform is provided, wherein the frame platform includes a shallow circular silo 1, a triangular support frame, a track, a mobile platform and a support plate 2.

[0024] Several triangular support frames are installed in a circular array on the outer wall of the silo, forming a circular support foundation. A circular track is installed on top of the triangular support frames, and the mobile platform moves on the track. The track enables the mobile platform to move in a circular motion, allowing operators to perform flexible operations.

[0025] Support plate 2 is fixed to the top of the triangular support frame near the outer wall of the silo. This provides excellent stability and strength, as it is fixed to both the triangular support frame and the outer wall of the silo. Support plate 2 forms an inverted L-shaped structure, with its top plate used to mount the steel pipe 18 that supports the cantilever panel.

[0026] The construction method includes the following steps: first, a number of triangular support frames are installed in a circular array on the outer wall of the shallow circular silo, and a support plate is simultaneously fixed to the top of one end of the triangular support frame close to the outer wall of the shallow circular silo, and the support plate is an inverted L-shaped structure. Then, a track is installed in a circular shape on the top of the triangular support frame, and then a mobile platform is moved and set on the track. Construction workers stand on the mobile platform to carry out construction and install the steel pipes used to support the eaves board on the support plate. After the steel pipes at one position are installed, the mobile platform moves to the next position to install the steel pipes at the next position.

[0027] The mobile platform consists of a platform deck 3, a protective fence 4, and track wheels 5. The protective fence 4 is welded to the top edge of the platform deck 3 in a U-shape, avoiding the side of the platform deck 3 that is closest to the outer wall of the silo. This provides a safe enclosure for workers and does not interfere with inward operations. The height of the two side edges of the protective fence 4 is lower than that of the stiffening plates 15 to avoid interference and ensure smooth passage of the mobile platform.

[0028] Track wheels 5 are compatible with the track and mounted on the bottom surface of the platform plate 3 to enable sliding movement of the platform. Preferably, the track wheels 5 are arranged in two layers, inner and outer, with at least two on each layer, to ensure sliding stability. The track wheels 5 are equipped with built-in brakes. Operators can lock the wheels by applying the brakes, thereby locking the platform in place and providing a stable working base.

[0029] The track includes an inner track 6 and an outer track 7. The inner track 6 and the outer track 7 are concentric circle structures to ensure smooth and accurate sliding of the mobile platform. The inner track wheel 5 runs on the inner track 6, and the outer track wheel 5 runs on the outer track 7.

[0030] The triangular support frame includes a horizontal plate 8, a connecting plate 9, a diagonal support plate 10 and a U-shaped groove 16. The inner end of the horizontal plate 8 is connected to the upper end of the connecting plate 9, and the outer end of the horizontal plate 8 is connected to the U-shaped groove 16. The outer track 7 is arranged in the U-shaped groove 16. The connecting plate 9 is arranged vertically and connected to the outer side wall of the shallow circular warehouse 1. The two ends of the diagonal support plate 10 are respectively connected to the connecting plate 9 and the U-shaped groove 16, and the inner track 6 is directly arranged on the horizontal plate 8.

[0031] The top plate of support plate 2 is shorter than the horizontal plate 8. A longer span of horizontal plate 8 is essential for arranging the rails and the mobile platform. The lower end of the vertical plate of support plate 2 is integrated with the top of connecting plate 9, facilitating manufacturing and eliminating the need for connecting the two, while also strengthening the overall structure. A stiffening plate 15 is installed inside support plate 2, positioned at an angle above the outer shell to enhance the support capacity of the top plate of support plate 2.

[0032] Bolts connect the horizontal plate 8 to the connecting plate 9, the diagonal brace plate 10 to the connecting plate 9, and the diagonal brace plate 10 to the U-shaped channel 16. The U-shaped channel 16 and the horizontal plate 8 are welded. The outer rail 7 is positioned within the U-shaped channel 16 and bolted to the bottom of the U-shaped channel 16. The inner rail 6 rests on the horizontal plate 8 and is connected to the horizontal plate 8 by welding or bolts. The connecting plate 9 and the vertical plates of the support plate 2 are fixed to the warehouse wall with removable anchor bolts.

[0033] It also includes a driving mechanism for driving the mobile platform to move, providing power for the movement of the mobile platform. The driving mechanism includes a rack 11, a gear 12 and a driving motor 13. The rack 11 is placed in a ring shape on the outside of the outer wall of the shallow circular warehouse, and the gear 12 is engaged with the rack 11. The driving motor is installed on the platform plate 3 and is connected to the gear 12. The driving motor 13 drives the gear 12 to rotate, and the gear 12 is engaged with the rack 11 to push the platform plate 3 in the opposite direction, thereby realizing the self-movement of the mobile platform. Specifically, the driving motor 13 can be driven by a belt, a chain or the output shaft is directly connected to the gear 12. The specific transmission connection method can be selected according to the type of the driving motor 13.

[0034] A housing 14 is located outside the rack 11 and gear 12. This annular housing structure features an annular through-hole on the side of the housing 14 closest to the platform plate 3. This housing 14 is connected to the support plate 2. Specifically, a mounting plate 17 is fixed to the bottom of the housing 14. Mounting plates 17 correspond to the support plates 2 and are bolted to the vertical plates of the support plate 2. This housing 14 provides protection for the gear 12 and rack 11.

[0035] Compared with the prior art, which requires a large number of wooden boards to pave the entire platform and for construction workers to stand and perform construction, the present application can effectively save the use of wooden boards by setting up a mobile platform.

[0036] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
