[0002] In the prior art, a long auger pile driver is mostly used for the construction of cast-in-place piles. The main drill pipe of the long auger pile driver is driven by power to rotate. The drill bit under the main drill pipe and the long auger blades arranged on the main drill pipe can drill a pile hole at one time, and then concrete is poured into the pile hole through the hollow main drill pipe to form a pile.

[0003] The existing auger pile driver mainly consists of a vehicle body, a pile driving mechanism mounting frame and a pile driving mechanism. The pile driving mechanism is rotatably installed on the vehicle body, which is convenient for flipping and adjusting during pile driving, and is convenient for flipping and placing the pile driving mechanism on the vehicle body for transportation when not in use.

[0004] At present, due to the large volume of the pile driver, it is generally parked outdoors, and the pile driving mechanism has been exposed to the outside. It is extremely easy to produce rust under the long-term irradiation of rain and sunlight, which affects the service life of the pile driving mechanism.

[0005] In view of this, this technical solution proposes a pile driving device for cast-in-place piles, which is convenient to better solve the above-mentioned problems. Content of the Utility Model

A positioning bolt one is threadedly connected inside the pile driving mechanism mounting frame and the moving frame. A positioning bolt two for fixing the moved moving frame is threadedly connected to the left side of the pile driving mechanism mounting frame.

[0009] In a preferred embodiment, a vehicle body is provided below the driving pile mechanism mounting frame, a left support frame is fixed to the left side of the vehicle body, and the left support frame is rotatably mounted with the driving pile mechanism mounting frame. A hydraulic cylinder for lifting and adjusting the driving pile mechanism mounting frame is rotatably mounted between the vehicle body and the driving pile mechanism mounting frame.

[0010] In a preferred embodiment, a right support frame for supporting the right side of the driving pile mechanism mounting frame is fixed to the right side of the top of the vehicle body.

[0011] In a preferred embodiment, the left side of the sliding groove is an open structure and the right side is a closed structure, and both the sliding groove and the slider are T-shaped structures.

[0012] In a preferred embodiment, both the telescopic protective cover and the moving frame are U-shaped structures, and the bottom of the telescopic protective cover fits against the top of the driving pile mechanism mounting frame.

At this time, the driving pile mechanism mounting frame can be vertically and horizontally stored and adjusted. At the same time, the right support frame can support the driving pile mechanism mounting frame after horizontal adjustment.

[0017] 2. In the present utility model, by taking out the first positioning bolt from the inside of the slider, and then pulling the moving frame to the left, the telescopic protective cover can be extended.
