Technical Field

[0001] This utility model belongs to the field of hydraulic pile technology, specifically relating to a pile extraction component for hydraulic piles. Background Technology

[0002] To prevent foundation collapse, a large number of piles are typically driven into the ground around the construction site during excavation work in water conservancy projects. These piles are then removed after the project is completed. The traditional method of removing the piles involves first using an excavator to remove part of the filling material around the piles, and then using lifting equipment to pull the piles out of the foundation.

[0003] However, existing pile extraction components often lack foldable casters, making it inconvenient to move them. Furthermore, existing pile extraction components often lack the ability to replace different support pads, making them unsuitable for different soil types and causing inconvenience during use. Therefore, there is an urgent need for a pile extraction component for hydraulic piles to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a pile extraction component for hydraulic piles, so as to solve the problems mentioned in the background art that the existing pile extraction components often do not have foldable casters, making it inconvenient to move the pile extraction components, and the existing pile extraction components often do not have the function of replacing different support pads.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pile extraction assembly for hydraulic piles, comprising a pile extraction machine body, a moving structure, and a supporting structure. The pile extraction machine body includes a base, with cylinder bodies of cylinders fixedly connected to the four top corners of the base, and grippers fixedly connected to the piston rods of the four cylinders. The moving structure includes hinges, with a support plate rotatably connected to the left and right ends of the base via the hinges. Two casters are fixedly connected to the bottom of the hinges, and two limiting plates are fixedly connected to the left and right ends of the base. Pins are slidably connected to the support plate and the limiting plates. The supporting structure includes a load-bearing seat, with the load-bearing seat fixedly connected to the left and right ends of the bottom of the base. Sliding grooves are provided at the front and rear ends of the load-bearing seat, and sliders are slidably connected to the sliding grooves. Buckles are fixedly connected to the bottom of the sliders.

[0006] Preferably, a handle is fixedly connected to the top of the support plate, and the surface of the handle is provided with an anti-slip coating.

[0007] Preferably, the bottom of the support plate is provided with a circular hole, and the middle of the limiting plate is provided with a circular hole. The circular holes of the support plate and the limiting plate are both corresponding to the pin.

[0008] Preferably, the front end of the pin is provided with a pull ring, and the rear end of the pin is engaged with a pin.

[0009] Preferably, the slider is fixedly connected to buckles on both the left and right sides, and the inner walls of both ends of the slide groove are provided with slots, and the buckles engage with the slots.

[0010] Preferably, the bottom of the slider is fixedly connected to a second support plate, and the bottom of the second support plate is fixedly connected to a rubber pad, the bottom surface of which is provided with an uneven pattern.

[0011] Preferably, the bottom of the buckle is fixedly connected with several pins.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of hydraulic pile extraction assembly features a movable structure. The operator holds the handle at the top of the support plate and lowers the support plate, which is connected to both sides of the base, outwards. At this point, the support plate is hinged to the base, creating a rotatable connection. The casters at the ends of the support plate then contact the ground. When the support plate is lowered to align with the limiting plate of the base, a pin is simultaneously inserted into the corresponding holes on both the support plate and the limiting plate. This fixes the support plate in place, preventing it from rotating freely. The weight of the entire device is then primarily supported by the four casters. The operator can easily move the pile extraction machine to the work site like a handcart. The movable structure allows for switching between "moving" and "working" modes. Operation is simple, requiring no additional tools, significantly reducing equipment preparation and dismantling time, and improving overall work efficiency. 2. This type of hydraulic pile extraction assembly features a support structure. The load-bearing capacity and stability of the equipment are ensured by this support structure. The load-bearing seats on both sides of the base are connected to the slider via internal grooves. Operators can pull the slider out or push it in from the grooves. The latches fixed on both sides of the slider engage with the slots on the inner wall of the grooves, firmly locking the slider in the extended position. After locking, the support plate at the bottom of the slider presses firmly against the ground. The support plate has two bottom surface configurations: one uses a support plate with a rubber pad on the bottom surface, which increases friction, prevents slippage, and cushions some vibration; the other uses a support plate with pins on the bottom surface. The sharp pins can penetrate deeply into the soil, providing strong anti-slip and anti-overturning capabilities. The rubber pad is suitable for hard surfaces such as cement and asphalt, preventing scratches and providing slip resistance; the pins are suitable for soft surfaces such as soil and sand, ensuring absolute stability under harsh conditions. This allows the pile extraction machine to be used in a variety of different construction sites. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides an embodiment of a pile extraction assembly for hydraulic piles, comprising a pile extraction machine body 1, a moving structure 2, and a support structure 3. The pile extraction machine body 1 includes a base 11, with cylinder bodies of cylinders 12 fixedly connected to the top four corners of the base 11, and grippers 13 fixedly connected to the piston rods of the four cylinders 12. The moving structure 2 includes a hinge 21, with support plates 22 rotatably connected to the left and right ends of the base 11 via the hinge 21. Two casters 24 are fixedly connected to the bottom of the hinge 21, and two limiting plates 26 are fixedly connected to the left and right ends of the base 11. Pins 25 are slidably connected to the support plates 22 and the limiting plates 26. The support structure 3 includes a load-bearing seat 31, with load-bearing seats 31 fixedly connected to the left and right ends of the bottom of the base 11. Slide grooves 32 are provided at the front and rear ends of the load-bearing seat 31, with sliders 34 slidably connected to the slide grooves 32, and buckles 35 fixedly connected to the bottom of the sliders 34.

[0017] Furthermore, a handle 23 is fixedly connected to the top of the support plate 22. The surface of the handle 23 is provided with an anti-slip coating. This design enhances the stability and comfort of holding the handle and makes it easier for the operator to apply force.

[0018] Furthermore, a round hole is provided at the bottom of the support plate 22 and a round hole is provided in the middle of the limiting plate 26. The round holes of the support plate 22 and the limiting plate 26 correspond to the pin 25. This hole-matching design ensures that the components can be accurately aligned and achieve a fast and reliable connection and fixation.

[0019] Furthermore, a pull ring is provided at the front end of the pin 25, and a pin is engaged at the rear end of the pin 25. The pull ring facilitates quick insertion and removal of the pin 25, while the end pin effectively prevents it from accidentally falling off.

[0020] Furthermore, buckles 35 are fixedly connected to both sides of the slider 34, and slots 33 are provided on the inner walls of both ends of the slide groove 32. The buckles 35 engage with the slots 33. The cooperation between the buckles 35 and the slots 33 enables the rapid locking and releasing of the slider 34 position, making operation simple.

[0021] Furthermore, the bottom of the slider 34 is fixedly connected to the support plate 36, and the bottom of the support plate 36 is fixedly connected to the rubber pad 37. The bottom surface of the rubber pad 37 is provided with uneven patterns, which can significantly increase the friction with the ground and effectively prevent the equipment from sliding during operation.

[0022] Furthermore, the bottom of the buckle 35 is fixedly connected with several pins 38. The sharp pins 38 can be deeply embedded in the soil, providing strong anti-slip and anti-overturning capabilities.

[0023] Working principle: During use, the operator holds the handle 23 on the top of the support plate 22 and lowers the support plate 22, which is connected to both sides of the base 11, outward. At this time, the support plate 22 is rotatably connected to the base 11 through the hinge 21, so that the casters 24 at the end of the support plate 22 contact the ground. When the support plate 22 is lowered to be aligned with the limiting plate 26 of the base 11, the pin 25 is simultaneously inserted into the corresponding round holes on the support plate 22 and the limiting plate 26. In this way, the support plate 22 is fixed and cannot be rotated at will. At this time, the weight of the entire equipment is mainly borne by the four casters 24. Operators can easily move the pile extractor body 1 to the work site like a wheelbarrow. The moving structure 2 can switch between "moving" and "working" modes. The operation is simple and does not require additional tools, which greatly reduces the time for equipment preparation and withdrawal and improves the overall work efficiency. The load-bearing and stability of the equipment is the responsibility of the support structure 3. The load-bearing seats 31 located on both sides of the bottom of the base 11 are connected to the slider 34 through the internal sliding groove 32. Operators can pull the slider 34 out or push it in from the sliding groove 32. The buckles 35 fixed on the left and right sides of the slider 34 will engage with the slots 33 on the inner wall of the sliding groove 32, thereby firmly locking the slider 34 in the extended position. After locking, the support plate 36 at the bottom of the slider 34 will be pressed tightly against the ground. The support plate has two bottom surface configurations. One uses a support plate with rubber pads 37 on the bottom surface. The rubber pads 37 increase friction, prevent the equipment from sliding, and also cushion some vibrations. The other uses a support plate with pins 38 on the bottom surface. The sharp pins 38 can penetrate deeply into the soil, providing extremely strong anti-slip and anti-overturning capabilities. The rubber pads 37 are suitable for hard surfaces such as cement and asphalt, preventing scratches and providing slip resistance. The pins 38 are suitable for soft surfaces such as soil and sand, ensuring absolute stability under harsh working conditions. This allows the pile extractor to be used in a variety of different construction sites.
