Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a device for removing old piles. Background Technology

[0002] In the construction phase of building and water conservancy projects, driving reinforced concrete square piles is a common method for foundation and slope reinforcement. With the continuous adjustments to land use planning, operations involving the removal, extraction, and relocation of existing square piles are becoming increasingly necessary. Considering the original purpose of the reinforced concrete square piles, the pile foundations are driven deep into the ground. Furthermore, the soil density around the piles increases due to the compression from the superstructure during construction and use. This new construction phase places higher demands on the removal of old square piles. Simultaneously, some projects, considering the need to protect the stability of the original superstructure, foundation, and slope, and to minimize the impact on the surrounding environment, further increase the difficulty of removing old square piles. When old piles are no longer usable, they need to be removed. Nowadays, when removing old piles, an excavator is needed to dig the soil around the old pile. When the bottom of the old pile is dug, it can be removed. However, digging the soil with an excavator takes a lot of time, and the construction is inconvenient because the surrounding area is full of old buildings.

[0003] Therefore, a device for removing old piles is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of time-consuming soil excavation by excavators and inconvenient construction due to the surrounding old buildings, this utility model proposes an old pile removal device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The old pile removal device of this utility model includes a sleeve, a connecting plate fixedly connected to the outside of the sleeve, an installation component provided inside the sleeve, a removal component provided inside the installation component, the removal component includes an installation frame slidably connected inside the installation component, a first rotating rod fixedly connected inside the installation frame, a gripping plate rotatably connected to the outside of the first rotating rod, and the outside of the gripping plate slidably connected to the inside of the installation frame.

[0006] Preferably, a limiting component is provided on the outer side of the gripping plate. The limiting component includes a second rotating rod rotatably connected to the inside of the gripping plate. Both ends of the second rotating rod are fixedly connected to rotating wheels. A sliding groove is slidably connected to the outer side of the rotating wheel. The sliding groove is opened inside the mounting frame.

[0007] Preferably, the installation assembly includes a placement frame fixedly connected inside the sleeve, a rotating shaft rotatably connected inside the placement frame, a turntable fixedly connected to the top of the rotating shaft, a limit rod fixedly connected to the top of the turntable, and a knob fixedly connected to the bottom of the rotating shaft.

[0008] Preferably, the mounting assembly further includes a mounting rod fixedly connected to the bottom of the placement frame, a limiting block slidably connected to the outside of the mounting rod, and a spring fixedly connected between the limiting block and the mounting rod.

[0009] Preferably, the mounting frame is slidably connected to the inside of the placement frame, and the outer side of the gripping plate is slidably connected to the inside of the placement frame.

[0010] Preferably, the outer side of the turntable is slidably connected to the inside of the mounting frame, the outer side of the turntable is slidably connected to the inside of the placement frame, the outer side of the limiting rod is slidably connected to the inside of the placement frame, and the outer side of the limiting rod is slidably connected to the inside of the mounting frame.

[0011] Preferably, the outer side of the limiting block is slidably connected to the inside of the knob, and a buckle groove is provided inside the limiting block.

[0012] The advantages of this utility model are: 1. This utility model involves fitting a sleeve around the outside of the old pile, allowing the outside of the old pile to slide against the outside of the gripping plate. This causes the gripping plate to rotate along the first rotating rod, preventing the gripping plate from affecting the movement of the sleeve. When the sleeve is fully fitted around the outside of the old pile, it can be raised, causing the gripping plate to abut against its outside. The end of the gripping plate abuts against the outside of the old pile, preventing the gripping plate from rotating back to its original position. As the sleeve rises, it can lift the old pile, thereby removing it. This reduces the time required for soil excavation, lowers the difficulty of construction, and improves work efficiency.

[0013] 2. This utility model compresses the spring by pulling the limiting block, thereby separating the limiting block from the knob. Then, rotating the knob drives the rotating shaft to rotate, which in turn moves the turntable and the limiting rod, thus separating the limiting rod from the mounting frame. This facilitates the disassembly of the mounting frame and allows for the replacement of different sized removal components, thus adapting to old piles of different sizes and improving the adaptability of the device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1-4 As shown, an old pile removal device includes a sleeve 1, a connecting plate 2 fixedly connected to the outside of the sleeve 1, an installation assembly inside the sleeve 1, a removal assembly inside the installation assembly, and a removal assembly including an installation frame 11 slidably connected inside the installation assembly. A first rotating rod 13 is fixedly connected inside the installation frame 11, and a gripping plate 14 is rotatably connected to the outside of the first rotating rod 13. The outside of the gripping plate 14 is slidably connected to the inside of the installation frame 11.

[0019] During operation, the sleeve 1 is fitted onto the outside of the old pile, causing the outside of the old pile to slide against the outside of the gripping plate 14. This allows the gripping plate 14 to rotate along the first rotating rod 13, ensuring that the gripping plate 14 does not affect the movement of the sleeve 1. Once the sleeve 1 is fully fitted onto the outside of the old pile, the sleeve 1 can be raised, causing the gripping plate 14 to abut against its outside. The end of the gripping plate 14 abuts against the outside of the old pile, preventing the gripping plate 14 from rotating back to its original position. As the sleeve 1 rises, it can lift the old pile, thus removing it. This reduces the time required for soil excavation and lowers the difficulty of construction, thereby improving work efficiency.

[0020] The gripping plate 14 is provided with a limiting component on its outer side. The limiting component includes a second rotating rod 15 rotatably connected to the inside of the gripping plate 14. Both ends of the second rotating rod 15 are fixedly connected to rotating wheels 16. A sliding groove 12 is slidably connected to the outer side of the rotating wheel 16. The sliding groove 12 is opened inside the mounting frame 11.

[0021] During operation, the rotation of the gripping plate 14 drives the second rotating rod 15 to move, which in turn drives the rotating wheel 16 to move inside the slide groove 12, thereby limiting the range of movement of the gripping plate 14.

[0022] The mounting frame 11 is slidably connected to the inside of the placement frame 3, and the outer side of the gripping plate 14 is slidably connected to the inside of the placement frame 3.

[0023] During operation, when the gripping plate 14 is slidably connected to the inside of the mounting frame 11, the gripping plate 14 can move along the sleeve 1, so that the gripping plate 14 will not obstruct the movement of the sleeve 1.

[0024] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the installation component includes a placement frame 3 fixedly connected inside the sleeve 1, a rotating shaft 4 rotatably connected inside the placement frame 3, a turntable 5 fixedly connected to the top of the rotating shaft 4, a limit rod 6 fixedly connected to the top of the turntable 5, and a knob 7 fixedly connected to the bottom of the rotating shaft 4.

[0025] The installation assembly also includes an installation rod 8 fixedly connected to the bottom of the placement frame 3, a limit block 9 slidably connected to the outside of the installation rod 8, and a spring 10 fixedly connected between the limit block 9 and the installation rod 8.

[0026] During operation, by pulling the limiting block 9, the spring 10 is compressed, thereby separating the limiting block 9 from the knob 7. Then, the knob 7 is rotated, which drives the rotating shaft 4 to rotate, thereby moving the turntable 5 and the limiting rod 6, thus separating the limiting rod 6 from the mounting frame 11. This facilitates the disassembly of the mounting frame 11 and allows for the replacement of different sized removal components, thus adapting to old piles of different sizes and improving the adaptability of the device.

[0027] Among them, the outer side of the turntable 5 is slidably connected to the inside of the mounting frame 11, the outer side of the turntable 5 is slidably connected to the inside of the placement frame 3, the outer side of the limiting rod 6 is slidably connected to the inside of the placement frame 3, and the outer side of the limiting rod 6 is slidably connected to the inside of the mounting frame 11.

[0028] During operation, the rotation of turntable 5 drives the movement of limit rod 6, thereby limiting the position of mounting frame 11.

[0029] The outer side of the limiting block 9 is slidably connected to the inside of the knob 7, and a buckle groove is provided inside the limiting block 9.

[0030] During operation, the limit block 9 and the knob 7 are slidably connected, so that the limit block 9 can restrict the rotation of the knob 7, and the opening of the slot makes it easy to pull the limit block 9 to move.

[0031] The working principle is as follows: by fitting the sleeve 1 onto the outside of the old pile, the outside of the old pile slides against the outside of the gripping plate 14, causing the gripping plate 14 to rotate along the first rotating rod 13. This prevents the gripping plate 14 from affecting the movement of the sleeve 1. When the sleeve 1 is fully fitted onto the outside of the old pile, the sleeve 1 can be raised, causing the gripping plate 14 to abut against its outside. The end of the gripping plate 14 abuts against the outside of the old pile, preventing the gripping plate 14 from rotating back to its original position. As the sleeve 1 rises, it can pull the old pile up, thereby reducing the time required for soil excavation and lowering the difficulty of construction, thus improving work efficiency.
