Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a pile extractor for water conservancy projects. Background Technology

[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] A search revealed a Chinese patent with publication number CN222140029, which discloses a hydraulic pile extraction machine. Its key technical features include: a base plate; a driving mechanism on the top side of the base plate; a clamping mechanism at the center of the top side of the base plate; and a moving mechanism on the bottom side of the base plate. The driving mechanism includes a hydraulic cylinder, with a hydraulic rod slidably mounted inside the hydraulic cylinder. A support plate is fixed to the bottom end of the hydraulic rod, and a support seat is fixed to the top end of the hydraulic cylinder. A connecting rod is rotatably mounted on the support seat, and a limit ring is set at the top end of the connecting rod. A connecting seat is fixed to the circumference of the limit ring, and a screw is rotatably inserted into the circumference of the limit ring. After clamping and fixing the pile, the hydraulic cylinder is controlled to extend the inner hydraulic rod, pulling up the pile. When the hydraulic rod reaches its maximum extension, the fixation of the pile is released, and the base plate is moved back to the ground. At this time, the top end of the pile is located inside the limit ring, and rotating the screw presses it against the surface of the pile, thus providing support. This solves the problem of existing pile extraction machines easily tipping over due to a shift in the center of gravity.

[0004] However, the existing technology lacks a rotating mechanism, resulting in greater resistance during pile extraction and lower extraction efficiency. To address the low extraction efficiency in the existing technology, this application proposes a new solution by extending and retracting the first hydraulic rod to rotate the drive plate and central ring, thereby enabling the clamping block to pull out the pile while simultaneously rotating the pile at a different angle. This makes the pile easier to loosen, reducing the resistance to extraction and improving extraction efficiency. Utility Model Content

[0005] In view of the above-mentioned background technology, there are shortcomings and defects in the existing technology, such as low pile extraction efficiency.

[0006] This utility model discloses a pile extractor for water conservancy projects. The pile extractor includes a support plate, a first hydraulic rod rotatably mounted on the upper surface of the support plate, a downward support ring fixedly connected to the support plate, a lower positioning ring rotatably connected to the lower support ring, a central ring fixedly connected to the lower positioning ring, and positioning rods arranged at equal angles slidably connected inside the central ring. A clamping block is fixedly connected to one end of each positioning rod, and a rack is fixedly connected to the outer surface of each clamping block. A drive plate is provided above the support plate, and a support plate is fixedly connected to the support plate.

[0007] Furthermore, a gear is provided on one side of each rack, and a toothed ring is rotatably connected to the outer surface of the central ring.

[0008] Furthermore, a worm gear is rotatably connected to the outer surface of the central ring, and a worm is provided on one side of the worm gear.

[0009] Furthermore, the outer surface of the central ring is fixedly connected with limiting members arranged at equal angles, and the outer surface of each clamping block is fixedly connected with limiting strips arranged at equal intervals.

[0010] Furthermore, two support plates are fixedly connected to the upper surface of the drive plate, and a motor is fixedly installed on the upper surface of the drive plate.

[0011] Furthermore, a base is provided below the lower support ring, and two second hydraulic rods are fixedly installed on the upper surface of the base.

[0012] Furthermore, the central ring is fixedly connected to an upper positioning ring, the upper positioning ring is rotatably connected to an upper support ring, and rectangular plates are fixedly connected to both sides of the upper support ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a central ring and a drive plate, and through the cooperation between the central ring and the drive plate, enables the first hydraulic rod to drive the central ring and other components to rotate within a certain angle via the drive plate, thereby causing the pile body fixed by the clamping block to rotate accordingly. This achieves the effect of reducing pile extraction resistance and improving pile extraction efficiency by setting up a drive plate with a central ring.

[0015] 2. This utility model, by setting up components such as worm gear and worm wheel, and through the mutual cooperation between the worm gear and worm, enables the worm to drive the gear ring to rotate, thereby causing the gear ring to drive the rack and clamping block to move through the gears, thus achieving the effect of locking the gear ring and other components by setting up the worm gear and worm.

The rack 8 drives the clamping block 7 to abut against the outer surface of the pile body, thereby fixing the pile body.

[0025] Each rack 8 has a gear 11 on one side. A toothed ring 12 is rotatably connected to the outer surface of the central ring 5.

The second hydraulic rod 20 is then activated, moving upwards via the lower support ring 3 and the central ring 5, thus pulling out the pile. The first hydraulic rod 2 is then activated, extending and retracting to drive the drive plate 9 and the central ring 5 to reciprocate within a certain angle, thereby rotating the pile body while pulling it out.
