Example

[0026] like Figure 1 As shown, a column top operating platform includes a bottom frame 1, a pad 2 is placed on the upper end of the bottom frame 1, the pad 2 is provided with a plurality of blocks and is fan-shaped, laid on the bottom frame 1, and then surrounded by a circular ring structure, the edge of the bottom frame 1 is connected with a guardrail 3 for protection, the inner side of the bottom frame 1 is rotatably connected with a plurality of connecting rods 4, and the other end of the connecting rod 4 is connected to the preset side ear of the side wall of the main body, that is, the connecting rod 4 is used to fix the entire operating platform to the column, and a through hole is reserved at one end of the connecting rod 4, and the above structure adopts a splicing method, so that the operating platform has a high degree of fragmentation, which is conducive to transportation.

[0027] Figure 2 As shown, the bottom frame 1 is an annular structure surrounded by a plurality of unit groups, and the unit groups include an outer rod 11, a radial rod 12 and an inner rod 13. The outer rod 11 and the inner rod 13 are respectively rotatably connected to the two ends of the radial rod 12, and the other ends of the outer rod 11 and the inner rod 13 are slidably connected to the adjacent radial rod 12. When two adjacent unit groups are in a connected state, the outer rod 11 and the inner rod 13 of one unit group are slidably connected to the radial rod 12 of the other unit group. When the two radial rods 12 are close to each other, the ends of the outer rod 11 and the inner rod 13 slide and tend to be parallel to the radial rod 12, that is, the two unit groups are in a folded state. Similarly, when the adjacent unit groups on the bottom frame 1 are disconnected, the entire bottom frame 1 can also be folded for easy transportation. After the construction is completed, it is also more convenient to remove the bottom frame 1 from the column.

[0028] Combination Figure 3 and Figure 5As shown, the radial rod 12 is provided with a first sliding hole 121 and a second sliding hole 122. The first sliding hole 121 and the second sliding hole 122 are both extended along the longer side of the radial rod 12. The length of the first sliding hole 121 and the second sliding hole 122 is related to the folding of the bottom frame 1. The end of the outer rod 11 is slidably fitted in the second sliding hole 122, and the end of the inner rod 13 is slidably fitted in the first sliding hole 121.

[0029] The ends of the outer rod 11 and the inner rod 13 are threadedly connected with fixing bolts 15, and the fixing bolts 15 pass through the first sliding hole 121 / the second sliding hole 122, that is, the outer rod 11 and the inner rod 13 are located below the radial rod 12. During installation, the fixing bolts 15 first pass through the first sliding hole 121 / the second sliding hole 122, and then are threadedly connected to the inner rod 13 / the outer rod 11. By tightening the fixing bolts 15, the radial rod 12 and the inner rod 13 and the outer rod 11 are fixedly connected. The end side walls of the fixing bolts 15 are provided with retaining springs 16. The retaining springs 16 are provided to prevent the fixing bolts 15 from falling off the device and affecting reuse. When the bottom frame 1 is disassembled from the column, the two fixing bolts 15 need to be removed, that is, the two unit groups are disconnected. At this time, the retaining springs 16 on the two fixing bolts 15 are removed in advance, and the fixing bolts 15 can be rotated to remove them.

[0030] A rotating pin 14 is provided at both ends of the radial rod 12. The outer rod 11 and the inner rod 13 are rotatably connected to the radial rod 12 through the rotating pin 14. The rotating pin 14 is stamped to expand its two ends to fix the rotating pin 14. The rotating pin 14 can also be replaced by a bolt and nut. However, it should be noted that the bolt and nut need to be prevented from being lost, such as by adding a retaining spring 16.

[0031] Combination Figure 3 and Figure 4 As shown, the guardrail 3 includes a vertical rod 32 and a horizontal rod 34. One end of the horizontal rod 34 is fixedly connected to the side wall of the vertical rod 32. The vertical rod 32 and the horizontal rod 34 constitute the main structure of the guardrail 3. A plurality of horizontal rods 34 can be provided as needed, and in order to further improve the safety effect, a plate can be installed on the horizontal rod 34.

[0032] The lower end of the vertical rod 32 is fixedly connected with a connector 31, and a socket 123 is provided on the radial rod 12. The connector 31 and the socket 123 cooperate, that is, the connector 31 is inserted into the socket 123 to achieve the installation of the guardrail 3 on the bottom frame 1. This installation method is simple and fast.

[0033] The side wall of the vertical rod 32 is provided with a buckle hole 33, and the other end of the cross rod 34 is fixedly connected with an insert 35. The buckle hole 33 and the insert 35 cooperate with each other. There are multiple guardrails 3. When two adjacent guardrails 3 cooperate, the insert 35 of one guardrail 3 is inserted into the buckle hole 33 of the other guardrail 3. By splicing the guardrails 3 and connecting the guardrails 3 and the bottom frame 1, the overall stability of the guardrail 3 can be improved.
