[0002] A pile puller is a machine used to pull pile pipes out of the ground. It has been widely used in construction engineering, bridge engineering, road engineering and other fields. Its working principle is to lift and extract the pile pipe from the soil through mechanical force, usually driven by a hydraulic system or an electric system. Since the pile pipe is rammed into the ground and has a certain depth, there is a certain resistance when pulling out the pile pipe. Traditional pile pulling components are often not easy to pull the pile pipe out of the ground during the pile pulling process, especially when the pile pipe is rammed into the ground to a deep degree and the pile pipe is embedded in the ground firmly. The resistance during pile pulling is greater, and the pile puller will be detached from the pile pipe, resulting in the inability to pull out the pile pipe and low efficiency of the pile pulling operation.

[0034] Reference Figure 1 The present application shows a schematic diagram of the overall structure of a circular cone sleeve. The cone sleeve 7 includes at least two cone sleeve units, and a handle 13 is fixed on the cone sleeve 7, wherein at least two handles 13 are provided on the cone sleeve 7, and the handles 13 are respectively arranged on different cone sleeve units. One end of the handle 13 is fixed in the cone sleeve 7, and the other end extends in a direction away from the cone sleeve 7 to form an L-shaped structure.
[0035] The handle 13 facilitates placing the cone sleeve 7 in the pile pipe 9 or taking the cone sleeve 7 out of the pile pipe 9. When the cone sleeve 7 is placed in the pile pipe 9, the L-shaped structure of the cone sleeve 7 can clamp the edge of the pile pipe 9 to prevent the cone sleeve 7 from falling during the pile extraction process.
[0036] Reference Figure 2 As shown, at least two cone sleeve units are arranged to form a cone sleeve 7, and a cone through hole 11 is arranged inside the cone sleeve 7. The cone through hole 11 extends axially along the cone sleeve 7, and the diameter of the end close to the handle 13 is smaller than the diameter of the end away from the handle 13. When pulling a pile, the cone rod 16 is inserted into the cone through hole 11, and the cone rod 16 fits inside the cone sleeve 7. The taper of the cone through hole 11 is consistent with the taper of the cone rod 16, and the outline size of the cone through hole 11 and the cone rod 16 are consistent, so that the cone rod 16 is in conflict with the inner side of the cone sleeve 7, and the binding force is increased when pulling a pile, so that the pile pipe 9 can be pulled out conveniently.
[0037] In a feasible embodiment, the cross-sectional profile of the cone sleeve 7 is set to be an arc shape, which can fit with the inner wall of the circular pile pipe 9, wherein at least part of the side of the cone sleeve 7 that fits with the inner wall of the pile pipe 9 is provided with a barbed tooth 10, which is used to increase the friction when pulling the pile. Figure 1 and Figure 3 As shown, the present application shows a schematic diagram of providing barbed teeth 10 on the outside of the cone sleeve 7. When pulling the pile, the pile pulling rod 6 is pulled upward, and the cone rod 16 squeezes the cone sleeve 7, squeezing the barbed teeth 10 to be tightly pressed against the inner wall of the pile pipe 9, which can increase the friction force and smoothly pull out the pile pipe 9.
[0038] The cone sleeve 7 is provided with a mounting hole 12, which is arranged radially along the cone sleeve 7. When pulling out the pile, the cone sleeve pin 8 passes through the hole on the pile pipe 9 and is inserted into the mounting hole 12. Even if there is great resistance when pulling out the pile, the pile pipe 9 can be smoothly pulled out from the ground. In order to improve the stability of the connection between the cone sleeve 7 and the pile pipe 9, at least two mounting holes 12 are provided on the cone sleeve 7, and the mounting holes 12 are respectively arranged on different cone sleeve units.
[0039] The present application provides barbed teeth 10 and mounting holes 12 on the cone sleeve 7, so as to prevent the cone sleeve 7 from being separated from the pile pipe 9 when pulling out the pile. Even if the pile pulling resistance is large, the pile pipe 9 can still be smoothly pulled out from the ground.
[0040] The pile pipe 9 has two structures: round and square. In order to pull out the pile pipe 9, the outer side of the cone sleeve 7 can also be set to a square according to the structure of the pile pipe 9, such as Figure 4 When the outer side of the cone sleeve 7 is set to a square structure, a handle 13 is fixed on the cone sleeve 7, a conical through hole 11 extending along the axial direction of the cone sleeve 7 is provided inside the cone sleeve 7, a barbed tooth 10 is provided on the side where at least part of the cone sleeve 7 is in contact with the inner wall of the pile pipe 9, and a mounting hole 12 is radially provided on the cone sleeve 7, and the mounting hole 12 is used to install the cone sleeve pin 8. Since the square cone sleeve 7 and the round cone sleeve 7 have the same function, the present application will not repeat them here.
[0041] Reference Figure 5 As shown, the utility model shows a schematic diagram of a pile puller. According to an embodiment of the utility model, a pile puller comprises a fixing mechanism 1, a bearing mechanism 2, a pile pulling mechanism 3 and a cone sleeve 7, wherein the fixing mechanism 1 is connected to the bearing mechanism 2, one end of the bearing mechanism 2 is connected to the pile pulling mechanism 3, the pile pulling mechanism 3 comprises a first shackle 4, a second shackle 5 and a pile pulling rod 6, the bottom of the pile pulling rod 6 is set as a cone rod 16, the cone rod 16 is placed in the pile pipe 9, the cone sleeve 7 is installed in the pile pipe 9, and the cone sleeve 7 can wrap the cone rod 16.
[0042] By means of the above-mentioned pile puller structure, the present application can smoothly pull out the pile pipe 9 from the ground, thereby improving the pile pulling efficiency.
[0043] like Figure 5 As shown, the upper end of the fixing mechanism 1 can be connected to a pile pulling machine, which is a liftable pile pulling machine that can drive the pile puller to pull piles. The bottom of the fixing mechanism 1 is connected to a bearing mechanism 2, which is used to bear the force of the impact hammer and drive the pile pulling mechanism 3 to pull piles. In a feasible embodiment, the bearing mechanism 2 can be a bearing plate.
[0044] A first pin hole is provided on the bottom of the fixing mechanism 1 and the carrying mechanism 2. The first pin 3 passes through the first pin hole to swingably connect the fixing mechanism 1 and the carrying mechanism 2. The first end of the carrying mechanism 2 is connected to the first shackle 4 through the second pin 14. The second end is connected to the impact hammer. The impact hammer strikes the carrying mechanism 2 to drive the carrying mechanism 2 to swing. In a feasible embodiment, the impact hammer is a hydraulic hammer.
[0045] The first shackle 4 and the second shackle 5 are both set as U-shaped structures, the opening end of the first shackle 4 faces upward, the opening end of the second shackle 5 faces downward, the first shackle 4 and the second shackle 5 are mutually buckled, the U-shaped opening end of the first shackle 4 and the bearing mechanism 2 are both provided with a second pin shaft hole, the second pin shaft 14 passes through the second pin shaft hole to connect the first shackle 4 with the bearing mechanism 2, the U-shaped opening end of the second shackle 5 is provided with a third pin shaft hole, the third pin shaft 15 passes through the third pin shaft hole and the through hole at the upper end of the pile pulling rod 6 to connect the second shackle 5 with the pile pulling rod 6. The impact hammer strikes the bearing mechanism 2, driving the first shackle 4 to swing, the first shackle 4 transmits the force to the pile pulling rod 6 through the second shackle 5, the pile pulling rod 6 is pulled upward, and the pile pipe 9 is pulled out of the ground.
[0046] The bottom of the pile pulling rod 6 is set as a tapered rod 16, and the diameter of the upper end surface of the tapered rod 16 is smaller than the diameter of the lower end surface, so that the tapered rod 16 can squeeze the pile puller cone sleeve 7 and pull out the pile pipe 9 when pulling piles.
[0047] like Figure 5As shown, the direction in which the impact hammer applies force to the bearing mechanism 2 is indicated by the arrow in the figure. When pulling a pile, the impact hammer is connected to one end of the bearing mechanism 2, the pile pulling machine is turned on, and the impact hammer swings rapidly to apply force to the bearing mechanism 2, driving the bearing mechanism 2 to swing rapidly. The bearing mechanism 2 drives the first shackle 4 and the second shackle 5 to pull the pile pulling rod 6 upward. During the process of pulling the pile pulling rod 6 upward, the cone rod 16 squeezes the cone sleeve 7 to pull the pile pipe 9 out of the ground.
[0048] The pile puller cone sleeve and pile puller provided in the present application can stably fix the cone sleeve and the pile pipe through the barbed teeth and the mounting holes provided on the cone sleeve of the pile puller, thereby preventing the cone sleeve from detaching from the pile pipe when pulling out the pile. Even if the resistance encountered during pile pulling is large, the pile pipe can still be pulled out smoothly, thereby improving the efficiency of pile pulling.
[0049] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
