[0007] Furthermore, the cleaning structure includes a pair of fan-shaped cleaning plates, and the pair of fan-shaped cleaning plates are fixedly connected together at one end away from the outer arc surface of the pair of fan-shaped cleaning plates, and each of the fan-shaped cleaning plates is provided with a bevel at one end.

[0017] Furthermore, extrusion cylinders are arranged on both sides of the control board, and output ends of the extrusion cylinders face the side walls of the pile hole.

[0018] By adopting the above technical solution and arranging the squeezing cylinders on both sides, after the control board is lowered, the squeezing cylinders are driven so that the output ends of the squeezing cylinders squeeze the side walls of the pile hole, thereby fixing the control board.

[0019] Furthermore, a buffer layer is fixedly connected to the output end of the extrusion cylinder.

[0020] By adopting the above technical solution, the buffer layer is provided to reduce damage to the output end of the extrusion cylinder.

[0021] Furthermore, the buffer layer is made of polymer material.

[0022] Furthermore, a method for cleaning sediment from a supporting rotary bored pile hole is applicable to a device for cleaning sediment from a supporting rotary bored pile hole as described in any one of the above technical solutions, and comprises the following steps: S1. Place the placement frame outside the pile hole to ensure that the connecting frame can rotate smoothly; S2. Operate the winding device to drive the driving teeth by rotating the driving teeth, thereby rotating the connecting rod and slowly lowering the two connecting ropes; as the connecting ropes are lowered, the control panel gradually enters the pile hole until its bottom contacts the bottom of the pile hole; S3, start the extrusion cylinders on both sides, move their output ends toward the side wall of the pile hole, and gently squeeze the side wall; S4. The buffer layer can reduce the damage to the side wall of the pile hole and ensure that the control board is stably fixed in the pile hole; S5, start the forward and reverse motors, and drive the rotating shaft to rotate through the meshing of the active meshing teeth and the driven meshing teeth, and the rotating shaft drives the fan-shaped cleaning plate to rotate, and the inclined surface on the fan-shaped cleaning plate pushes the sediment at the bottom of the pile hole to the top of the fan-shaped cleaning plate; S6. When the inclined surface of the fan-shaped cleaning plate reaches the abutting inclined surface on the abutting plate, the fan-shaped cleaning plate will clean up the sediment in the area; S7. When the fan-shaped cleaning plate is rotating, if it is observed that there is still residual sediment at the bottom of the fan-shaped cleaning plate, the auxiliary cleaning structure can be started; S8, the second cleaning plate will move with the movement of the fan-shaped cleaning plate, pushing the sediment at the bottom of the fan-shaped cleaning plate to one side; S9. When the second cleaning plate needs to be recovered, the control plate can be slightly raised by adjusting the structure, so that the second cleaning plate returns to the placement slot as the connecting spring is compressed; S10.

With the precise coordination of the driving teeth and the driven teeth, the connecting rod slowly rotates, the two connecting ropes are steadily lowered, and the control board (composed of a pair of fan-shaped plates) gradually penetrates into the pile hole until its bottom precisely touches the bottom of the pile hole. At this time, the output end of the squeezing cylinder (specially equipped with a buffer layer to reduce damage) gently squeezes the side wall of the pile hole, ensuring the stable fixation of the control board and greatly reducing the potential damage to the pile hole structure.

[0024] The precise start of the forward and reverse motors, through the close meshing of the active and driven teeth, drives the rotating shaft to rotate efficiently, thereby driving the fan-shaped cleaning plate to rotate flexibly. The ingenious design of the inclined surface on the fan-shaped cleaning plate can effectively push the sediment at the bottom of the pile hole to its top, and when the inclined surface reaches the abutment inclined surface on the abutment plate, the sediment is completely cleaned. At the same time, the addition of the auxiliary cleaning structure (i.e., the second cleaning plate, which is flexibly connected to the bottom of the fan-shaped cleaning plate through a connecting spring) further improves the cleaning efficiency, especially when dealing with the sediment that may remain at the bottom of the fan-shaped cleaning plate, the second cleaning plate can move flexibly with the movement of the fan-shaped cleaning plate to push the sediment to one side.

[0025] When the second cleaning plate needs to be recovered, the control plate is slightly raised by adjusting the structure, and the second cleaning plate is easily returned to the placement slot as the connecting spring is compressed, which is both convenient and efficient. After the cleaning is completed, the connecting rope is slowly rolled up by reversing the winding device, and the control plate is stably lifted, while ensuring that the output end of the extrusion cylinder gradually separates from the side wall of the pile hole, avoiding unnecessary damage.

[0026] In summary, the present application includes the following beneficial technical effects: the supporting type rotary bored pile hole sediment cleaning device realizes efficient mechanized cleaning of sediment at the bottom of deep pile holes by integrating the adjustment structure and the cleaning structure and adopting the fan-shaped control panel design.

[0037] In this embodiment, refer to Figure 3The adjustment structure includes a connecting rope 22 fixedly connected to both ends of the control panel 1, and a winding device is arranged at the upper end of the connecting rope 22. The winding device includes a pair of connecting rods 21 and a connecting frame 2. The connecting rod 21 is horizontally installed on the connecting frame 2. Two connecting ropes 22 are respectively fixedly connected to the two connecting rods 21. The pair of connecting rods 21 are rotatably connected to the connecting frame 2. A driving tooth 23 is fixedly connected to the opposite end of each connecting rod 21. A driving rod 24 is rotatably arranged on the connecting frame 2. A driving tooth 25 is fixedly arranged on the driving rod 24. The driving tooth 25 meshes with the driving tooth 23 on the two connecting rods 21. A placing frame 4 placed outside the pile hole is arranged around the connecting frame 2. The placing frame 4 is placed outside the pile hole, and the driving tooth 25 is rotated to drive the driving tooth 23 on both sides to rotate, so that the connecting rod 21 is rotated, so that it simultaneously lowers the two connecting ropes 22, and realizes simultaneous up and down adjustment. In this application, a motor can also be used to drive the rotating tooth.

[0038] In this embodiment, the connecting frame 2 is rotatably connected to the placing frame 4, so as to facilitate the adjustment and control of the angle of the control panel 1 below.

[0039] In this embodiment, extrusion cylinders 33 are arranged on both sides of the control board 1, and the output ends of the extrusion cylinders 33 face the side walls of the pile hole. By setting the extrusion cylinders 33 on both sides, after the control board 1 is lowered, the extrusion cylinders 33 are driven so that the output ends of the extrusion cylinders 33 squeeze the side walls of the pile hole, thereby fixing the control board 1. A buffer layer 34 is fixedly connected to the output end of the extrusion cylinder 33. The buffer layer 34 is arranged to reduce damage to the output end of the extrusion cylinder 33.

[0040] A method for cleaning sediment from a supporting rotary bored pile hole, applicable to any one of the above technical solutions, and a device for cleaning sediment from a supporting rotary bored pile hole, comprising the following steps: S1, placing the placement frame 4 outside the pile hole to ensure that the connecting frame 2 can rotate smoothly; S2, operate the winding device, drive the driving teeth 23 by rotating the driving teeth 25, and then rotate the connecting rod 21, and slowly lower the two connecting ropes 22; as the connecting ropes 22 are lowered, the control board 1 (composed of a pair of fan-shaped boards) gradually enters the pile hole until its bottom contacts the bottom of the pile hole; S3, start the extrusion cylinders 33 on both sides, so that their output ends (with the buffer layer 34) move toward the side wall of the pile hole and gently squeeze the side wall; S4, the buffer layer 34 can reduce the damage to the side wall of the pile hole and ensure that the control board 1 is stably fixed in the pile hole; S5, start the forward and reverse motor 3, and drive the rotating shaft 12 to rotate through the meshing of the active meshing teeth 31 and the driven meshing teeth 32, and the rotating shaft 12 drives the fan-shaped cleaning plate 11 to rotate, and the inclined surface on the fan-shaped cleaning plate 11 pushes the sediment at the bottom of the pile hole to the top of the fan-shaped cleaning plate 11; S6. When the inclined surface of the fan-shaped cleaning plate 11 reaches the abutting inclined surface of the abutting plate 13, the fan-shaped cleaning plate 11 will clean up the sediment in the area; S7. When the fan-shaped cleaning plate 11 is rotating, if it is observed that there is still residual sediment at the bottom of the fan-shaped cleaning plate 11, the auxiliary cleaning structure can be started; S8, the second cleaning plate 41 (connected to the bottom of the fan-shaped cleaning plate 11 through the connecting spring 43) moves with the movement of the fan-shaped cleaning plate 11, pushing the sediment at the bottom of the fan-shaped cleaning plate 11 to one side; S9. When the second cleaning plate 41 needs to be recovered, the control plate 1 can be slightly raised by adjusting the structure, so that the second cleaning plate 41 returns to the placement groove 42 as the connecting spring 43 is compressed; S10, after the cleaning is completed, the connecting rope 22 is rolled up by reversely operating the winding device, thereby slowly lifting the control board 1; during the lifting process, ensure that the output end of the extrusion cylinder 33 gradually separates from the side wall of the pile hole to avoid unnecessary damage to the side wall.

[0041] By placing the placement frame 4 firmly outside the pile hole and ensuring that the connecting frame 2 can rotate smoothly, a solid foundation is provided for the entire cleaning operation. With the precise matching of the driving teeth 25 and the driving teeth 23, the connecting rod 21 rotates slowly, the two connecting ropes 22 are steadily lowered, and the control board 1 (composed of a pair of fan-shaped plates) gradually penetrates into the pile hole until its bottom accurately touches the bottom of the pile hole. At this time, the output end of the squeezing cylinder 33 (especially equipped with a buffer layer 34 to reduce damage) gently squeezes the side wall of the pile hole, ensuring the stable fixation of the control board 1, while greatly reducing the potential damage to the pile hole structure.

[0042] The precise start of the forward and reverse motor 3 drives the rotating shaft 12 to rotate efficiently through the close meshing of the active meshing teeth 31 and the driven meshing teeth 32, thereby driving the fan-shaped cleaning plate 11 to rotate flexibly. The inclined surface on the fan-shaped cleaning plate 11 is cleverly designed, which can effectively push the sediment at the bottom of the pile hole to its top, and when the inclined surface reaches the abutting inclined surface on the abutting plate 13, the sediment is thoroughly cleaned. At the same time, the addition of the auxiliary cleaning structure (i.e., the second cleaning plate 41, which is flexibly connected to the bottom of the fan-shaped cleaning plate 11 through the connecting spring 43) further improves the cleaning efficiency, especially when dealing with the sediment that may remain at the bottom of the fan-shaped cleaning plate 11, the second cleaning plate 41 can move flexibly with the movement of the fan-shaped cleaning plate 11 to push the sediment to one side.

[0043] When the second cleaning plate 41 needs to be recovered, the control plate 1 is slightly raised by adjusting the structure, and the second cleaning plate 41 is easily returned to the placement groove 42 as the connecting spring 43 is compressed, which is convenient and efficient. After the cleaning is completed, the connecting rope 22 is slowly rolled up by reversely operating the winding device, and the control plate 1 is stably lifted, while ensuring that the output end of the extrusion cylinder 33 gradually separates from the side wall of the pile hole, avoiding unnecessary damage.

[0044] Specific implementation process: First, move the device as a whole to the vicinity of the pile hole to be cleaned, and ensure that the placement frame 4 is firmly placed outside the pile hole. Next, check all components, including the connecting rope 22, the winding device, the driving device, the cleaning structure, etc., to ensure that they are in good working condition. Then, operate the driving gear 25 of the winding device to drive the gear 23 to rotate the connecting rod 21, thereby releasing the connecting rope 22, so that the control panel 1 and the cleaning structure at the bottom thereof slowly descend into the pile hole. During the descent process, observe the degree of relaxation of the connecting rope 22 to ensure that the control panel 1 descends smoothly and avoids collision with the pile hole wall. When the control panel 1 approaches the bottom of the pile hole, stop releasing the connecting rope 22 and prepare for sediment cleaning. At this time, start the extrusion cylinders 33 on both sides of the control panel 1, so that the output end of the cylinder faces the side wall of the pile hole and applies a certain pressure, and the friction with the pile hole wall is reduced through the buffer layer 34, while providing sufficient fixing force to ensure that the control panel 1 remains stable during the cleaning process. Next, firstly, the second cleaning plate 41 is allowed to touch the ground by adjusting the structure, and the elasticity of the connecting spring 43 is used to make the second cleaning plate 41 close to the bottom of the pile hole. Then, the driving device (forward and reverse motor 3) is started to drive the rotating shaft 12 to rotate, thereby causing the fan-shaped cleaning plate 11 to start rotating. The inclined surface on the fan-shaped cleaning plate 11 pushes the sediment at the bottom of the pile hole to the fan-shaped cleaning plate 11. When the inclined surface reaches the abutting inclined surface on the abutting plate 13, the fan-shaped cleaning plate 11 cleans the sediment from the abutting inclined surface. At the same time, the second cleaning plate 41, driven by the rotation of the fan-shaped cleaning plate 11, pushes the sediment at the bottom of the fan-shaped cleaning plate 11 to one side, further cleaning the bottom of the pile hole. During the cleaning process, the cleaning effect is observed, and the speed and cleaning time of the driving device are adjusted as needed. After the cleaning is completed, the driving device is turned off to stop the rotation of the fan-shaped cleaning plate 11. Then, the reverse drive of the winding device is operated to rotate the connecting rod 21 and tighten the connecting rope 22, and the control plate 1 and the cleaning structure at its bottom are slowly lifted back to the outside of the pile hole. During the lifting process, it is also necessary to observe the tension of the connecting rope 22 to ensure that the control panel 1 rises smoothly. Finally, after the control panel 1 and its cleaning structure are completely removed from the pile hole, all power supplies and drive devices are turned off, and the cleaning device is inspected and maintained as necessary to ensure that it can work normally the next time it is used, and the site is cleaned and the device and related tools are properly stored.

[0045] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.

A method for cleaning sediment from a supporting rotary bored pile hole, applicable to a device for cleaning sediment from a supporting rotary bored pile hole as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1, placing the placement frame (4) outside the pile hole to ensure that the connecting frame (2) can rotate smoothly; S2, operate the winding device, drive the driving teeth (23) by rotating the driving teeth (25), and then rotate the connecting rod (21), and slowly lower the two connecting ropes (22); as the connecting ropes (22) are lowered, the control board (1) gradually enters the pile hole until its bottom contacts the bottom of the pile hole; S3, start the extrusion cylinders (33) on both sides, so that their output ends with the buffer layer (34) move toward the side wall of the pile hole and gently squeeze the side wall; S4, the buffer layer (34) can reduce damage to the side wall of the pile hole and ensure that the control board (1) is stably fixed in the pile hole; S5, starting the forward and reverse motor (3), driving the rotating shaft (12) to rotate through the meshing of the active meshing teeth (31) and the driven meshing teeth (32), the rotating shaft (12) drives the fan-shaped cleaning plate (11) to rotate, and the inclined surface on the fan-shaped cleaning plate (11) pushes the sediment at the bottom of the pile hole to the top of the fan-shaped cleaning plate (11); S6. When the inclined surface of the fan-shaped cleaning plate (11) reaches the abutting inclined surface of the abutting plate (13), the fan-shaped cleaning plate (11) will clean up the sediment in the area; S7. When the fan-shaped cleaning plate (11) is rotating, if it is observed that there is still residual sediment at the bottom of the fan-shaped cleaning plate (11), the auxiliary cleaning structure can be started; S8, the second cleaning plate (41) is connected to the bottom of the fan-shaped cleaning plate (11) through the connecting spring (43) and moves with the movement of the fan-shaped cleaning plate (11), pushing the sediment at the bottom of the fan-shaped cleaning plate (11) to one side; S9. When the second cleaning plate (41) needs to be recovered, the control plate (1) can be slightly raised by adjusting the structure, so that the second cleaning plate (41) returns to the placement groove (42) as the connecting spring (43) is compressed; S10, after the cleaning is completed, the connecting rope (22) is rolled up by reversely operating the winding device, thereby slowly lifting the control board (1); during the lifting process, it is ensured that the output end of the squeezing cylinder (33) gradually separates from the side wall of the pile hole to avoid unnecessary damage to the side wall.
