Description

Technical Field

[0001] The present application relates to the technical field of pile hole protection, and in particular to a wind power engineering cast-in-place pile hole protection tool. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free renewable energy source that has been used for a long time, mainly through windmills to pump water, grind flour, etc. In wind power projects, concrete pouring is required, and when concrete is poured, cast-in-place piles are required. When not pouring, protective tools are needed to protect the cast-in-place pile holes to prevent people and large objects from falling in.

The conical and rubber protective cover can form a sealed protection on the top of the bored pile, and can guide water to avoid water accumulation on the top of the device.

[0008] Preferably, a socket is provided inside the protective grid, and the magnetic rod is engaged with the socket.

[0009] By inserting the magnetic rod into the inside of the socket, the friction between the protective grid and the protective cover is increased, thereby improving the stability of the installation of the protective cover.

[0010] Preferably, the top of the protective ring is fixedly connected to a fixing rod, and the top of the fixing rod is fixedly connected to a fixing ring.

[0011] A protection can be formed on the top of the protective ring by means of the fixing ring and the fixing rod, and an external construction hook can also be hung on the periphery of the fixing ring.

[0012] Preferably, a connecting rod is fixedly connected to the top of the protective grid on the side close to the magnetic rod, and rotating blocks are fixedly connected to both sides of the connecting rod.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] By inserting the device into the outer periphery of the bored pile of the wind power project, inserting the insertion rod through the positioning ring into the soil, and then screwing the positioning rod to make it contact with the bored pile, the stability of the device installation is improved to prevent the device from being offset by external force. By screwing the protective grid to the top of the limit ring, a protection is formed on the top of the bored pile by the protective grid to prevent workers or larger objects from falling into the bored pile. By installing the protective cover on the top of the protective grid, the magnetic rod is inserted into the protective grid of magnetically attractive metal materials. The protective cover can form a sealed protection on the top of the bored pile and can guide water to avoid water accumulation on the top of the device, so that the staff can freely choose grid protection or closed sealed bored pile hole according to their needs, which increases the function of the device and meets more usage requirements.
