Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0030] It should be noted that the embodiments in the present application and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0031] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] As shown in Figures 1-5 The present embodiment proposes a water conservancy project pile pulling device, which comprises a base 1 and a top plate 2, and a rotating pile pulling mechanism 3 is installed at the bottom of the top plate 2.

[0033] As shown in Figure 2 The rotating pile pulling mechanism 3 comprises a motor 301, a rotating shaft 302, a pile pulling shaft 303, a first pulley 304, a second pulley 305, a connecting belt 306, a mounting disc 307, a support table 308, an electric push cylinder 309 and a clamping ring 310. The motor 301 is fixedly installed on the top plate 2, one end of the rotating shaft 302 is cooperatively installed on the output end of the motor 301, the pile pulling shaft 303 is rotatably connected to the middle part of the top plate 2, the first pulley 304 is installed on the output end of the rotating shaft 302 through a connecting key, the second pulley 305 is installed on the pile pulling shaft 303 through a connecting key and is located at the bottom of the top plate 2, the connecting belt 306 is installed on the first pulley 304 and the second pulley 305, the mounting disc 307 is fixedly installed at one end of the bottom of the pile pulling shaft 303, the support table 308 is fixedly installed on one side of the base 1, the electric push cylinder 309 is fixedly installed on the support table 308, and the output end of the electric push cylinder 309 is connected to the bottom of the top plate 2. The clamping ring 310 is fixedly installed on the mounting disc 307 by bolts. In use, select a suitable clamping ring 310 to be fixed on the mounting disc 307, first clamp the pile body, then the motor 301 works to drive the rotating shaft 302 to rotate, the rotating shaft 302 drives the pile pulling shaft 303 to rotate through the first pulley 304, the second pulley 305 and the connecting belt 306, and transmits power to the pile body to make the pile body start to rotate, then the electric push cylinder 309 works to make the pile body gradually pull out of the ground while rotating, and in the pile pulling process, the pile body is in a spiral upward state to reduce the loss and resistance generated by direct hard pulling.

[0034] As shown in Figure 1 and Figure 3As shown, threaded holes 4 are provided at both ends of the base 1, and fixing pins 5 are provided inside the threaded holes 4. The fixing pins 5 are symmetrically distributed on the base 1. After the device is moved to a suitable location, the fixing pins 5 are inserted into the ground to make the entire device stably fixed to the ground.

[0035] like Figure 1 As shown, a guide rod 6 is slidably connected between the top plate 2 and the base 1. A bushing 7 is installed on the guide rod 6, and the guide rod 6 is symmetrically distributed at both ends of the top plate 2. While the top plate 2 moves up and down, the guide rod 6 can ensure the stability of the movement between the base 1 and the top plate 2.

[0036] like Figure 1 As shown, one bottom end of the guide rod 6 is fixedly mounted on the base 1, and reinforcing ribs 8 are symmetrically installed between the base 1 and the guide rod 6 to enhance the strength of the base 1.

[0037] like Figure 5 As shown, there are two sets of clamping rings 310, and both sets of clamping rings 310 are semi-cylindrical. The positions of the two sets of clamping rings 310 can be adjusted and ultimately determined by bolts. The two sets of semi-cylindrical clamping rings 310 can be used for piles of different diameters.

[0038] like Figure 2 As shown, the diameter of the first pulley 304 is smaller than the diameter of the second pulley 305, and the connecting belt 306 is a V-belt. During use, the smaller diameter of the first pulley 304 compared to the second pulley 305 reduces the rotational speed of the pile-pulling shaft 303 and increases its torque.

[0039] like Figure 2 As shown, two sets of lighting systems 9 are fixedly installed at the bottom of the top plate 2. The lighting systems 9 are powered by an external power source. The lighting systems 9 consist of LED lights to illuminate the construction environment and facilitate pile extraction.

[0040] Specifically, the pile extraction device used in water conservancy projects operates as follows: when the device reaches a suitable location, the fixing pin 5 is inserted into the ground to stably fix the entire device to the ground. A suitable clamping ring 310 is selected and fixed on the mounting plate 307 to first clamp the pile body. Then, the motor 301 works, driving the rotating shaft 302 to rotate. The rotating shaft 302 drives the pile extraction shaft 303 to rotate through the first pulley 304, the second pulley 305 and the connecting belt 306, transmitting power to the pile body and causing the pile body to start rotating. Then, the electric pusher cylinder 309 works, causing the pile body to gradually be pulled out of the ground while rotating. During the pile extraction process, the pile body is in a spiral upward state, reducing the loss and resistance caused by direct hard pulling.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
