[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, a quick pipe extraction device includes a support rod 1, a pressure rod 2 and a locking mechanism 3. The support rod 1 is used to support the entire device. It is connected to the middle section of the pressure rod 2 and can rotate freely around the connection point (the connection point serves as a fulcrum). Specifically, the support rod 1 and the pressure rod 2 are connected by a connecting block 5 fixed on the pressure rod 2. A pin hole is provided at the upper end of the support rod 1, and a pin hole 51 is also provided on the connecting block 5. The support rod 1 and the pressure rod 2 are connected by a pin passing through the pin hole 51. Three pin holes 51 are provided on the connecting block 5. The three pin holes 51 are distributed in parallel and at intervals along the length direction of the pressure rod 2. By selecting different pin holes 51, the distance difference from the fulcrum to the two ends of the pressure rod 2 can be adjusted, which makes it more convenient and easy to extract the pipe pile.

[0026] One end of the pressure rod 2 is a pressure end, and the other end is connected to the locking mechanism 3 through a rope 4; the distance from the pressure end of the pressure rod 2 to the connection point with the support rod 1 is several times the distance from the other end to the connection point, which makes tube removal more labor-saving; the locking mechanism 3 includes a locking frame 31 and left and right fixed blocks 32, 33 (which can be made of rubber material), and the left and right fixed blocks 32, 33 are symmetrically fixed to the locking frame 31 through a connecting shaft 34 and can rotate freely around the connecting shaft 34; pull rings 35 for connecting to the rope 4 are provided on the back surfaces of the left and right fixed blocks 32, 33.

[0027] The connecting end of the pressure rod 2 and the locking mechanism 3 is Y-shaped, forming two forked ends, which are respectively connected to the pull rings 35 on the left and right fixed blocks 32 and 33 of the locking mechanism. When the pipe is pulled out, the pipe pile is just located between the two forked ends; the forked ends of the pressure rod 2 are both provided with a card slot 21 with an upward opening; one end of the rope 4 is connected to the left fixed block 32, the middle section is engaged in the card slot 21, and the other end is connected to the right fixed block 33; only one rope 4 is used to ensure that the left and right fixed blocks 32 and 33 are evenly stressed.

[0028] The left and right fixing blocks 32 and 33 are provided with arc grooves 36 on the opposite sides thereof. The cross-sectional curvature of the grooves 36 is consistent with the curvature of the side of the pipe pile, which increases the contact area with the pipe pile, makes the force more uniform, and makes it easier to pull out the pipe. The lower corners of the opposite sides of the left and right fixing blocks 32 and 33 are chamfered (such as Figure 5 ), which also increases the contact area with the pipe pile and makes it easier to pull out the pipe.

[0029] When pulling out the pipe, put the locking mechanism 3 on the pipe pile, and the pipe pile is located between the left and right fixed blocks 32 and 33. Press the pressure rod 2, and the rope 4 pulls the left and right fixed blocks 32 and 33 to rotate. The left and right fixed blocks 32 and 33 squeeze and hold the pipe pile toward each other. Press the pressure rod 2 multiple times or continuously until the pipe pile is pulled out.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
