[0033] Base 201, the base 201 is fixed on the protective operation platform mechanism 2, and the top of the base 201 is rotatably connected with a rotating ring 202;

[0034] Barrel 203, the barrel 203 is installed on the top of the rotating ring 202, and the inside of the barrel 203 is communicated with the inside of the rotating ring 202;

[0035] Operation platform 204, the operation platform 204 is arranged outside the barrel 203 and is fixed to the barrel 203;

[0036] Drive motor 3, the drive motor 3 drives the base 201 to rotate self.

[0037] Toothed ring 205 is fixedly connected around the rotating ring 202, the output end of the drive motor 3 is fixedly connected with a gear 4, and the gear 4 meshes with the toothed ring 205.

[0038] Discharge pipe 206 is arranged on the inner wall of the rotating ring 202, the discharge pipe 206 is communicated with the inside of the barrel 203 and the rotating ring 202, and a gate valve 207 for controlling the discharge is arranged on the discharge pipe 206.

[0039] The base 201 is arranged in a conical structure to realize the automatic flow of the internal concrete to the outside.

[0040] The operation platform 204 is provided with operation holes 208 for controlling the gate valve 207. A plurality of the operation holes 208 are provided, and the plurality of operation holes 208 are evenly arranged in a ring shape.

[0041] A plurality of discharge pipes 206 are provided, and are evenly arranged on the circumferential side of the rotating ring 202, and the length of each discharge pipe 206 is different.

[0042] The operation platform 204 is a ring-shaped platform, and the outer side of the operation platform 204 is surrounded by an outer vertical plate.

[0043] The four corners of the load-bearing frame 1 are fixedly connected with support frames 5, and the tops of the support frames 5 are fixedly connected with the operation platform 204.

[0044] The load-bearing frame 1 serves as the basic support structure of the concrete placing device for the cable-stayed bridge, ensuring the stable placement of the device on the inner formwork of the pylon. The setting of the protective operation platform mechanism 2 not only provides a safe operation environment for workers, but also realizes the automatic pushing operation of concrete through the taper of the base 201, improving the work efficiency.

[0045] As Figure 1 、 Figure 2 and Figure 3 shown, on both sides of the load-bearing frame 1, a driving motor 3 for driving the swinging of the rotating ring 202 is fixedly connected through a bracket. The output end of the driving motor 3 is fixedly connected with a gear 4, and the gear 4 meshes with the toothed ring 205. Workers only need to simply operate to control the start and stop of the driving motor 3, thereby realizing the swinging of the rotating ring 202 and the concrete placing operation, improving the work efficiency, effectively reducing the labor intensity of workers, and enhancing the safety and convenience of the construction site.

[0046] As Figure 1 、 Figure 2 and Figure 3 shown, on the inner wall of the rotating ring 202, discharge pipes 206 are provided, and gate valves 207 for controlling the discharge are provided on the discharge pipes 206. The gate valves 207 for controlling the discharge provided on the discharge pipes 206 provide a more convenient and flexible operation method for workers. Workers can, according to actual needs, simply open and close the gate valves 207 to control the outflow and stop of concrete, improving the controllability and usability of the placing device, effectively reducing the labor intensity of workers, and enhancing the safety and work efficiency of the construction site.

[0047] As Figure 1 、 Figure 2 and Figure 3As shown, there are two sets of discharge pipes 206. The lengths of the two sets of discharge pipes 206 are different. Each set of discharge pipes 206 includes two discharge pipes 206. The four discharge pipes 206 are arranged in a cross-shaped structure, realizing discharging in four directions, effectively avoiding problems such as uneven cloth distribution and cloth leakage that may occur in traditional cloth distribution methods, improving the quality and overall effect of concrete cloth distribution. Since the discharge pipes 206 are arranged in a cross-shaped structure, the device is also more stable during the cloth distribution process, reducing the shaking and deviation caused by asymmetry.

[0048] As Figure 1 , Figure 2 and Figure 3 shown, operation holes 208 for controlling the gate valve 207 are opened on the operation platform 204. There are multiple operation holes 208, and the multiple operation holes 208 are arranged in a ring evenly.

[0049] As Figure 1 , Figure 2 and Figure 3 shown, the base 201 is arranged in a conical structure to realize the automatic outward flow of the internal concrete. The conical structure of the base 201 also makes the cloth distribution device more stable as a whole, reducing the shaking or deviation that may occur during the cloth distribution process, further ensuring the accuracy and safety of the cloth distribution operation, not only improving the work efficiency and quality of the cloth distribution device, but also bringing a more convenient and efficient work experience to the construction site.

[0051] As Figure 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: support frames 5 are fixedly connected to the four corners of the load-bearing frame 1, and the top of the support frames 5 is fixedly connected to the operation platform 204. The fixed connection between the top of the support frames 5 and the operation platform 204 not only provides a stable support for the operation platform 204, but also makes the workers feel more at ease when performing cloth distribution operations on the operation platform.

[0052] During implementation, it is placed on the inner formwork of the cable tower through the load-bearing frame 1, and the concrete is pumped into the hopper 203. The concrete flows outward along the cone on the base 201 to realize automatic pushing operation. The worker stands on the operation platform 204. After opening the gate valve 207 through the operation hole 208, the rotating ring 202 is driven by the driving motor 3, so that the discharge pipe 206 can swing left and right, and the concrete flows evenly in four directions through the discharge pipe 206. After the concrete pouring is completed, the gate valve 207 is closed.

[0053] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0054] 1. After the concrete is pumped into the hopper, it flows outward along the conical structure on the base, which can ensure the continuous operation of the concrete pump. By driving the rotating ring with the driving motor, the discharging pipe can swing left and right, and only one worker is needed to be responsible for the concrete distribution of the whole tower.

[0055] 2. The operation platform mechanism and the load-bearing frame improve the safety of the concrete distribution device during operation, providing a safe and convenient operation environment for workers.
