[0002] Landscape construction and other similar projects often involve a large number of pile extraction operations, which require pulling out square or round piles that are placed in the soil layer from the ground.

[0003] Currently, the common method is to tighten a steel wire rope around the pile, then start a winch to wind the wire rope and pull the pile out of the soil. Alternatively, a hydraulic pile extractor can be used, where a pile clamp is used to hold the pile, and a hydraulic cylinder forces pressure on the clamp, lifting the pile upwards a certain distance before pulling it out section by section from the soil. However, both methods require large frames, resulting in bulky equipment, difficulty in movement, and hindering the transport and maintenance of the pile extractor, severely impacting extraction efficiency.

[0004] Therefore, there is an urgent need to provide a portable pile extractor to reduce the labor intensity of workers and improve pile extraction efficiency. Utility Model Content

[0034] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] The portable pile extractor disclosed in this application can be used in situations such as pulling piles out of the ground, and of course it can also be used in other similar application scenarios. The portable pile extractor is described in detail below.

[0036] Example 1

[0037] See appendix Figure 1 — Figure 5 The diagram shows a preferred embodiment of a portable pile extractor according to this application. The portable pile extractor includes a support assembly 1, a power source 2 mounted on the support assembly 1, a screw lifting assembly 3 movably mounted on the support assembly 1 and connected to the power source 2, and a working assembly 4 detachably mounted on the screw slider 32 within the screw lifting assembly 3. When the power source 2 is activated, it drives the screw lifting assembly 3 to operate, causing the working assembly 4 to move up and down. The working assembly 4 then lifts the pile body to extract the pile.

[0038] This utility model uses a support component 1 to support the pile extractor; a power source 2 to drive the screw lifting component 3 to move, serving as the power source for pile extraction; the screw lifting component 3 transmits the power generated by the power source 2, enabling the working component 4 to move up and down to extract the pile from the ground; the working component 4 connects to or clamps the pile body, causing the pile body to rise and be extracted. Specifically, when the screw lifting component 3 drives the working component 4 to move up and down, the working component 4 can drive the pile in contact with it to rise and be extracted.

[0039] See appendix Figure 1 — Figure 5 As shown, in this utility model, the support assembly 1 includes a support column 11, a first bearing seat 12 and a second bearing seat 13 installed at both ends of the support column 11, a first bearing 14 installed on the first bearing seat 12, and a second bearing 15 installed on the second bearing seat 13. The second bearing 15 and the first bearing 14 are respectively connected to both ends of the lead screw lifting assembly 3.

[0040] This invention utilizes the support column 11 to support the power source 2 while simultaneously limiting and supporting the other end of the lead screw 31; the first bearing seat 12 provides support for the lead screw lifting assembly 3 and a mounting position for the first bearing 14; the first bearing 14 reduces the friction between the lead screw 31 and the first bearing seat 12 during rotation, making the rotation of the lead screw 31 smoother; the second bearing seat 13 provides a mounting position for the second bearing 15 and limits the other end of the lead screw 31. Together with the second bearing 15, this ensures that the lead screw 31 rotates while reducing friction, thus making the rotation of the lead screw 31 smoother.

[0041] See appendix Figure 3 — Figure 5 As shown, in this utility model, the support column 11 is provided with a through groove 111 and a guide limiting groove 112. The through groove 111 allows the lead screw 31 and lead screw slider 32 in the lead screw lifting assembly 3 to avoid each other, and the guide limiting groove 112 guides and limits the lifting movement of the lead screw slider 32 in the lead screw lifting assembly 3. It should be noted that the guide limiting groove 112 can connect the through groove 111 to the outside.

[0042] See appendix Figure 3 — Figure 5 As shown. In this utility model, the lead screw lifting assembly 3 includes a lead screw 31 and a lead screw slider 32 mounted on the lead screw 31; the working assembly 4 is mounted on the lead screw slider 32, and the two ends of the lead screw 31 are movably connected to the first bearing 14 and the second bearing 15 respectively. The end of the lead screw 31 that is movably connected to the second bearing 15 is connected to the power source 2 through a coupling.

[0043] This utility model uses a lead screw 31, which is driven by a power source 2 to rotate, causing the lead screw slider 32 to move up and down along the lead screw 31. The lead screw slider 32 provides an installation position for the working component 4 and drives the working component 4 to move up and down, thereby pulling out the pile.

[0044] See appendix Figure 2 — Figure 5 As shown, in this utility model, the lead screw slider 32 includes a lifting connection part 321 corresponding to the lead screw 31 and a mounting part 322 disposed on the lifting connection part 321. The mounting part 322 is provided with a plurality of mounting holes 323 for mounting the working component 4.

[0045] This utility model uses a lifting connection part 321 to mount a lead screw slider 32 on the lifting connection part 321 and connect it to the lead screw 31. When the lead screw 31 rotates, the lifting connection part 321 can move up and down. The mounting part 322 provides an installation position for the working component 4, so that the working component 4 can move up and down with the lifting connection part 321. The multiple mounting holes 323 allow for flexible installation of the working component 4 as needed.

[0046] See appendix Figure 1 and Figure 2 As shown, in this utility model, the working component 4 includes two mounting blocks 41 fixedly installed on the lead screw slider 32 in the lead screw lifting component 3, and a piling member 42 installed on the mounting blocks 41 for connecting the two mounting blocks 41. The piling member 42 is columnar.

[0047] See appendix Figure 3 — Figure 5As shown, a U-shaped block 113 is installed on the bottom end of the support column 11, and a base 114 is connected to the bottom of the U-shaped block 113; an mounting plate 131 is provided on the outer side wall of the second bearing seat 13, and the power source 2 is installed on the mounting plate 131, and the power source 2 is a motor; both the first bearing seat 12 and the second bearing seat 13 are provided with limiting grooves 121, and elastic retaining rings 122 are installed in the limiting grooves 121.

[0048] This utility model, through the setting of the U-shaped block 113, provides installation space for the support column 11, while allowing the U-shaped block 113 to be connected and limited to the support column 11 by bolts; through the setting of the base 114, it contacts the ground to support the pile extractor, increasing the contact area between the pile extractor and the ground, ensuring the stability of the pile extractor during use; through the setting of the mounting plate 131, it provides an installation position for the power source 2, allowing the power source 2 to be close to one end of the lead screw 31, facilitating subsequent connection; it should be noted that the power source 2 can rotate in both directions; through the setting of the limiting groove 121, it provides... The elastic retaining ring 122 provides an installation position and limits its movement, ensuring that it will not move arbitrarily after installation. The elastic retaining ring 122 also limits the position of the bearing. Specifically, the elastic retaining ring 122 installed on the first bearing housing 12 limits the first bearing 14, preventing it from separating from the top of the first bearing housing 12. The elastic retaining ring 122 installed on the second bearing housing 13 limits the second bearing 15, preventing it from separating from the top of the second bearing housing 13.

[0049] See appendix Figure 1 — Figure 5 As shown, the usage process of this utility model is as follows:

[0050] The workers move the pile extractor to the vicinity of the pile to be extracted, then start the power source 2, which drives the lead screw 31 to rotate, causing the lead screw slider 32 to move towards the ground for resetting. After resetting, the pile extractor 42 is inserted into the hole in the pile. The workers then start the power source 2 again, which drives the lead screw 31 to rotate, causing the lead screw slider 32 to move upwards, raising the working component 4 mounted on the lead screw slider 32. The pile is then pulled out of the ground by the pile extractor 42, completing the extraction. The workers then reverse the power source 2 to reset the working component 4, preparing for the next pile extraction. It should be noted that the pile extractor of this embodiment is suitable for piles with holes.

[0051] Example 2

[0052] See appendix Figure 6As shown, the difference between this embodiment and the above embodiment is that the pile pulling component 42 in this embodiment is block-shaped and has a spacer groove 421.

[0053] In this embodiment, the pile-pulling component 42 is set as a block shape, and with the setting of the interval groove 421, two columnar bodies that can be inserted into the pile body are formed on the pile-pulling component 42. The width of the interval groove 421 corresponds to the interval of two holes at the same height position on the pile body, so as to ensure that the pile-pulling component 42 can pull out the pile. Of course, this embodiment can also be used to pull out piles with enlarged heads. When pulling out piles with enlarged heads, the interval groove 421 can be matched with the pile body to support the enlarged head during the process of the pile-pulling component 42 rising, and the pile body can be pulled out.

[0054] Example 3

[0055] See appendix Figure 7 As shown, the difference between this embodiment and the above embodiment is that the pile pulling member 42, which is arranged in a block shape, is provided with a mounting post 422 that penetrates the pile pulling member 42, and nuts 423 are provided at both ends of the mounting post 422.

[0056] In this embodiment, the installation column 422 is used to penetrate the pile body and pull it out. Specifically, the installation column 422 passes through the pile-pulling member 42, and then both ends are locked with nuts 423. Then, the power source 2 starts working to pull the pile out of the ground. More specifically, the installation column 422 passes through the pile body and the pile-pulling member 42, and then the nuts 423 are locked and limited, after which the power source 2 is started to pull the pile out. It should be noted that, in order to facilitate the installation of the nuts 423, the outer wall of the pile-pulling member 42 is flat and perpendicular to the centerline of the installation column 422.

[0057] Example 4

[0058] See appendix Figure 8 As shown, the difference between this embodiment and the above embodiment is that in this embodiment, a hook 424 is movably installed on the mounting column 422. The hook 424 can be engaged with the hole structure on the pile body for hanging. When the power source 2 drives the working component 4 to lift and lower through the screw lifting assembly 3, it can drive the pile body to lift and lower.

[0059] Compared to the above embodiments, this embodiment only requires aligning the hook 424 with the hole in the pile body and then starting the power source 2. This embodiment is more convenient to install than embodiment 3.

[0060] Example 5

[0061] See appendix Figure 9As shown, the difference between this embodiment and the above embodiment is that the working component 4 in this embodiment includes a connecting block 43 with a connecting groove 44. The connecting block 43 is movably connected to the lead screw slider 32 in the lead screw lifting component 3 through the connecting groove 44, and the connecting block 43 is provided with a clamping groove 45.

[0062] In this embodiment, the clamping groove 45 is designed so that the pile body is placed in the clamping groove 45. As the connecting block 43 rises, the groove wall of the clamping groove 45 will come into contact with and rub against the outer wall of the pile body. Through the friction between the groove wall and the pile body, the pile body is pulled out.

[0063] Example 6

[0064] See appendix Figure 10 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, anti-slip rubber 451 is installed in the clamping groove 45.

[0065] This utility model increases the friction between the clamping groove 45 and the pile body by setting the anti-slip rubber 451, preventing the connecting block 43 from sliding with the pile body due to insufficient friction during pile extraction, thus preventing the pile from being extracted.

[0066] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
