DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following further describes the present application in detail Figures 1-5 with reference to the attached

[0036] Embodiment 1:

[0037] Embodiment 1 of the present application discloses a safety protection platform device for bored piles. Refer to Figure 1, the safety protection platform device for bored piles includes a counterweight base 1 and a surrounding guardrail 2. The counterweight base 1 is arranged in a rectangle, and two lifting lugs 11 are fixedly installed on the top of the counterweight base 1. The two lifting lugs 11 are distributed along the diagonal direction of the counterweight base 1, so that the equipment can lift the counterweight base 1 in a stable posture through the lifting lugs 11. Combined with Figure 2 , the counterweight base 1 is provided with a base through-hole 101. The base through-hole 101 is arranged close to the center of the counterweight base 1, and the inner diameter of the base through-hole 101 is larger than the inner diameter of the pile hole, so that the construction equipment can pass through the base through-hole 101 to construct the pile hole.

[0038] Refer to Figure 2 and Figure 3 , a base slot 102 is formed on the top of the counterweight base 1. The base slot 102 is arranged in a "mouth" shape and surrounds the base through-hole 101. The surrounding guardrail 2 includes a first railing 3 and a second railing 4, and there are two of each of the first railing 3 and the second railing 4. The two first railings 3 and the two second railings 4 are distributed in a "mouth" shape, and the two first railings 3 are arranged opposite to each other, and the two second railings 4 are also arranged opposite to each other. The bottoms of the first railing 3 and the second railing 4 are both inserted and matched with the base slot 102, so that the first railing 3 and / or the second railing 4 can be disassembled and installed on the counterweight base 1 by plugging and unplugging. In addition, the distance between the tops of the first railing 3 and the second railing 4 and the top of the counterweight base 1 is more than 1200 mm, so that it is not easy for people to step over the first railing 3 and the second railing 4.

[0039] Refer to Figure 3 and Figure 4 , four fixing rings 12 are fixedly installed on the counterweight base 1. The four fixing rings 12 are distributed in a rectangle, and two of the fixing rings 12 are located on one side of the first railing 3, and the other two fixing rings 12 are located on the other side of the second railing 4. The first railing 3 is provided with a fixing slot 301 along its own length direction. After the first railing 3 is inserted and matched with the base slot 102, the first railing 3 is further installed on the counterweight base 1 through a fixing rod 5 passing through the fixing ring 12 and the fixing slot 301, so as to ensure the stability of the first railing 3.

[0040] Refer to Figure 3 and Figure 4, two first connection holes 302 are penetrated through the first railing 3 in the direction of its own thickness, and the two first connection holes 302 are respectively located at both ends of the first railing 3. The second railing 4 is penetrated with a second connection hole 401 in the direction of its own length. After the first railing 3 and the second railing 4 are both inserted and matched with the base slot 102, the second railing 4 is installed on the first railing 3 through a connecting rod 6 passing through the first connection hole 302 and the second connection hole 401, so as to connect the first railing 3 and the second railing 4 into a whole in a way that is convenient for disassembly and assembly, thereby ensuring the overall stability of the enclosure guardrail 2.

[0041] The implementation principle of the bored pile safety protection platform device in Embodiment 1 of the present application is as follows:
