[0028] In the embodiment, as Figures 1-6As shown, the platform expansion base 3 is provided with seven rectangular grooves, and the seven reinforcing rods 5 on the platform base main body 1 are arranged in the seven rectangular grooves respectively. The left and right sides of the platform base main body 1 are each provided with seven cylindrical holes corresponding to the reinforcing rods 5, and one side of the platform expansion base 3 is provided with eight cylindrical holes corresponding to the reinforcing rods 5. When the platform expansion base 3 is unfolded, the reinforcing rods 5 on the platform base main body 1 will slide in the cylindrical holes on one side of the platform expansion base 3, and the reinforcing rods 5 on the platform expansion base 3 will slide in the cylindrical holes on the left and right sides of the platform base main body 1. Moreover, the reinforcing rods 5 will not be separated from the cylindrical holes on the platform base main body 1 and the platform expansion base 3 after the platform expansion base 3 is unfolded, thereby ensuring the overall strength of the platform base main body 1 and the platform expansion base 3.

[0029] In the embodiment, as shown in the figure, Figures 1-6 The expansion guardrail 4 can slide left and right in the rectangular groove inside the main guardrail 2 and tightly abut against the inner wall of the rectangular groove. When the platform expansion base 3 is adjusted left and right, the expansion guardrail 4 will slide in the rectangular groove inside the main guardrail 2, thereby ensuring the overall stability of the main guardrail 2 and the expansion guardrail 4.

[0030] In the embodiment, as shown in the figure, Figure 3 The limiting plates 7 can be slidably installed in the air slots between the two groups of positioning baffle plates 6 after the platform expansion base 3 is unfolded. After the platform expansion base 3 is unfolded, the two limiting plates 7 can be pushed from front to back between the two groups of positioning baffle plates 6 to the last side, so as to limit the sliding of the platform expansion base 3 and lock it.

[0031] In the embodiment, as shown in the figure, Figures 1-6 The expansion guardrail 4 is provided with a rectangular protruding block on one end of the front and back sides, and the main guardrail 2 is also provided with a corresponding open groove on the outer wall of the front and back sides.

When the platform expansion base 3 is adjusted left and right, the rectangular protruding block on one end of the front and back sides of the expansion guardrail 4 will also slide in the open groove on the outer wall of the front and back sides of the main guardrail 2, and can also play a limiting role.

[0032] In the embodiment, as shown in the figure, Figures 1-5As shown, the platform base body 1 is symmetrically provided with a total of sixteen rectangular grooves on the left and right sides, and the sixteen reinforcing rods 5 on the platform base body 1 are arranged in the sixteen rectangular grooves respectively, and the platform expansion base 3 can slide left and right in the rectangular grooves on the left and right sides of the platform base body 1. When the platform expansion base 3 is unfolded, the reinforcing rods 5 on the platform base body 1 will slide in the cylindrical holes on one side of the platform expansion base 3, and the reinforcing rods 5 on the platform expansion base 3 will slide in the cylindrical holes on the left and right sides of the platform base body 1. Moreover, the reinforcing rods 5 will not be separated from the cylindrical holes on the platform base body 1 and the platform expansion base 3 after the platform expansion base 3 is unfolded, thereby ensuring the overall strength of the platform base body 1 and the platform expansion base 3.

[0033] In Example Two, on the basis of Example One, as shown in Figures 1-6 As shown, the limiting plates 7 are also L-shaped plates, and a bolt is screwed to the front bottom of each limiting plate 7, and the bottom front side of the platform base body 1 is also provided with two circular holes corresponding to the bolts. After the platform expansion base 3 is unfolded, the two limiting plates 7 can be pushed from front to back between the two groups of positioning baffle plates 6 to the last side. The L-shaped limiting plates 7 can facilitate positioning when they are pushed, and the bolts can be screwed into the limiting plates 7 and the platform base body 1, thereby avoiding the movement of the limiting plates 7.

[0034] The working principle of the present embodiment is as follows: when high-altitude work needs to be performed using the device, the two platform expansion bases 3 are first pulled out from the left and right sides of the platform base body 1. During this process, the expansion guardrails 4 will slide in the rectangular grooves inside the main guardrails 2, and the rectangular protruding blocks on one end of the expansion guardrails 4 will slide in the opening grooves on the front and back outer walls of the main guardrails 2, and also serve as limiting elements. At the same time, the reinforcing rods 5 on the platform base body 1 will slide in the cylindrical holes on one side of the platform expansion base 3, and the reinforcing rods 5 on the platform expansion base 3 will slide in the cylindrical holes on the left and right sides of the platform base body 1. Moreover, the reinforcing rods 5 will not be separated from the cylindrical holes on the platform base body 1 and the platform expansion base 3 after the platform expansion base 3 is unfolded, thereby ensuring the overall strength of the platform base body 1 and the platform expansion base 3. Finally, the two limiting plates 7 are pushed from front to back between the two groups of positioning baffle plates 6 to the last side, thereby limiting the sliding of the platform expansion base 3 and locking it, and the bolts are screwed into the limiting plates 7 and the platform base body 1, thereby avoiding the movement of the limiting plates 7. Then, the device can be suspended by a cable or fixed on the top of an elevator, thereby enabling high-altitude work to be performed, and the side guardrails can prevent personnel from falling. After use, the platform expansion base 3 and the expansion guardrails 4 can be folded, thereby reducing the space occupied during storage and transportation.
