[0002] The position of the anti-pullout anchor piles in the basement renovated by the abandoned rotary drilling rig is deep, and they are generally guided by the connected pipe body, and the pipe body is also used for pouring concrete. However, the concrete forms resistance to the downward movement of the anchor piles and the pipe body, and the downward movement speed is slow, which is not conducive to improving the construction efficiency. The construction workers apply force to press down or move up and pull the anchor piles and the pipe body, which is laborious and time-consuming. The anchor piles that have just moved down to the set position are not in sufficient contact with the concrete, affecting the quality of the later project. Therefore, in view of the above problems, a simple and fast construction equipment for the anti-pullout anchor piles in the basement renovated by the abandoned rotary drilling rig is proposed.

[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] See also Figure 1-4 As shown, a simple and quick construction equipment for transforming an abandoned rotary drilling rig into a basement anti-pullout anchor pile comprises a hydraulic cylinder 1, a gantry block 2, a guide hole 201, a circular hole 202, a base frame 3, threaded steel bars 4, a compression-drawing pipe joint 5, a U-shaped seat 6, a rotating shaft 7, a hook 8, a U-shaped connecting rod 9, a bearing seat 10 and a torsion spring 11. The hydraulic cylinder 1 is fixedly connected to the circular hole 202 located in the middle of the gantry block 2, and threaded steel bars 4 are slidably installed in the guide holes 201 located at the four corners of the gantry block 2. Two U-shaped seats 6 are symmetrically installed at the front end of the top of the gantry block 2, and a rotating shaft 7 is rotatably installed in the U-shaped seat 6. The rotating shaft 7 and the hook 8 are hooked together, and one end of the hook 8 is fixedly connected to the corresponding part of the U-shaped connecting rod 9. Bearing seats 10 are rotatably installed on both sides of the middle of the U-shaped connecting rod 9, and a torsion spring 11 is provided between the bearing seat 10 and the U-shaped connecting rod 9.

[0020] Furthermore, two bearing seats 10 are provided, and the two bearing seats 10 are respectively installed on the top ends of two of the threaded steel bars 4 .

[0021] Furthermore, a compression-drawing pipe joint 5 is rotatably mounted on the push rod end of the hydraulic cylinder 1 , and the bottom end surface of the compression-drawing pipe joint 5 contacts the top end surface of the injection pipe 12 connected to the top of the anchor pile 13 .

[0022] Furthermore, one side of the bottom of the hook 8 is an upward inclined surface.

[0023] Furthermore, a plurality of connection holes are provided on both sides of the top of the base frame 3 , and the two connection holes on each side are fixedly connected to the bottoms of two threaded steel bars 4 , respectively.

[0024] When the utility model is in use, when it is necessary to fine-tune and lift the anchor pile 13 connected by the pressure column pipe 12, the hydraulic cylinder 1 extends the injection pipe 12 connected by the pressure-drawing pipe joint 5 to drive the anchor pile 13 to lift up, so that each part of the anchor pile 13 is fully in contact with the concrete, thereby improving the installation quality of the anchor pile 13;

[0025] When it is necessary to press the injection pipe 12 down into the concrete in the foundation pit, first press the pipe joint 5 to contact the top end face of the injection pipe 12, then manually operate and rotate the U-shaped connecting rod 9 to drive the connected hook 8 to separate from the rotating shaft 7 located in the U-shaped seat 6. Under the action of gravity, the gantry block 2 and the hydraulic cylinder 1 are in a synchronous self-weight drop to press the injection pipe 12 down, and the hydraulic cylinder 1 is in a gradually contracted state. After the injection pipe 12 is pressed into place, the hydraulic cylinder 1 extends again to move the connected gantry block 2 up along the threaded rod 4 to reset. At the same time, under the action of the torsion spring 11, the rotating shaft 7 pushes the bottom of the hook 8, so that the hook 8 rotates forward and then forward to reset, completing the secondary hooking and fixing of the hook 8 and the rotating shaft 7, which plays a role in fixing the gantry block 2, and at the same time, the hydraulic cylinder 1 shrinks and resets;

[0026] To sum up: the hydraulic cylinder is extended to drive the anchor pile to be lifted up through the injection pipe connected by the compression-drawing pipe joint, so that all parts of the anchor pile can fully contact the concrete, thereby improving the installation quality of the anchor pile, and the injection pipe is pressed into the concrete by utilizing the deadweight of the gantry crane block and the hydraulic cylinder, and the injection pipe is pressurized for the second time by the hydraulic cylinder being extended again, while the gantry crane block is reset, which has the function of controlling the lifting and lowering of the gantry crane block, reduces the number of hydraulic cylinders used, simplifies the equipment structure, and realizes the function of simple and fast construction.
