Description

Technical Field

[0001] The utility model relates to the technical field of building engineering construction, in particular to a soil cleaning device inside a building pile hole. Background Art

[0002] In the process of construction engineering, it is generally necessary to reserve a pile hole first, and then pour concrete and steel cage into the pile hole to form an underground building foundation with good load-bearing capacity and earthquake resistance. When drilling the pile hole, there is often a lot of soil in the pile hole that needs to be cleared. At this time, the soil inside the pile hole is usually cleared directly using an auger.

[0003] However, since the soil directly brought out by the auger is easily accumulated in the building pile hole, a large amount of accumulated soil is likely to fall into the building pile hole again during the operation, so multiple cleaning operations are required, and the cleaning efficiency is low.

[0032] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0033] See also Figures 1 to 3The present embodiment provides a soil cleaning device for the inside of a building pile hole, comprising a base 1, an annular discharge tray 2, a lifting assembly 3 and a rotating cleaning assembly 4. The base 1 is provided with a through hole connecting the top and bottom surfaces at the center position. The annular discharge tray 2 is accommodated in the through hole and is flush with the top surface of the base 1. A rotating centrifugal assembly 5 is arranged in the through hole. The rotating centrifugal assembly 5 is connected to the bottom surface of the annular discharge tray 2 and drives the annular discharge tray 2 to rotate around the axis. The lifting assembly 3 is arranged on the top surface of the base 1 and drives the rotating cleaning assembly 4 to rise and fall through the connecting plate 31. The auger rod 41 on the rotating cleaning assembly 4 is coaxially arranged above the annular discharge tray 2 and can penetrate into the middle through hole of the annular discharge tray 2.

[0034] Combination Figures 1 to 3 When the soil cleaning device for the interior of the building pile hole of the present embodiment is working, the middle through hole of the annular discharge plate 2 is first aligned with the building pile hole to be cleaned, so that the annular discharge plate 2 is located directly above the building pile hole to be cleaned; then, the lifting assembly 3 is started to make the auger rod 41 penetrate into the middle through hole of the annular discharge plate 2, and the rotating cleaning assembly 4 and the rotating centrifugal assembly 5 are started, so that the auger rod 41 discharges the soil in the building pile hole by rotation and moves it to the top surface of the annular discharge plate 2, and under the centrifugal force of the rotating centrifugal assembly 5, the soil on the annular discharge plate 2 is continuously thrown away from the building pile hole, thereby preventing the discharged soil from accumulating at the building pile hole.

[0035] Preferably, see Figures 1 to 3 An electric push rod 6 is vertically arranged at each of the four corners of the top surface of the base 1. The four electric push rods 6 are synchronously controlled, and a universal wheel 61 that can extend from the bottom of the base 1 is arranged at the bottom of each electric push rod 6. A fixed push plate 7 is arranged at one side edge of the top surface of the base 1, and a handle 71 is fixed on the plate surface of the fixed push plate 7 away from the base 1.

[0036] When using the soil cleaning device for the interior of a building pile hole of the present embodiment, first start the four electric push rods 6 to make the universal wheels 61 extend from the bottom of the base 1. At this time, the device can be pushed by the handle 71 and the fixed push plate 7 to move to the top of the building pile hole to be cleaned. Then, the four electric push rods 6 are started again to retract the universal wheels 61 into the base 1, so that the bottom of the base 1 can be in contact with the ground, which can improve the stability of the device during soil cleaning and reduce the pressure of the electric push rods 6 to prevent the electric push rods 6 from being damaged by vibration during the soil cleaning process.

[0037] Preferably, see Figure 4A limiting ring 11 is provided on the base 1, and the annular discharge plate 2 can be freely rotated and limitedly installed in the limiting ring 11. The rotating centrifugal assembly 5 includes a gear ring 51 and a first drive motor 52. The gear ring 51 is coaxially fixed on the bottom surface of the annular discharge plate 2, and the first drive motor 52 is fixed on the base 1, and the driving end of the first drive motor 52 is meshed with the inner ring teeth of the gear ring 51 through the driving gear 53.

[0038] After the first drive motor 52 is started, it drives the gear block 53 to drive the gear block ring 51 to rotate. Because the gear block ring 51 is coaxially fixed with the annular discharge tray 2, it further drives the annular discharge tray 2 to rotate. As the annular discharge tray 2 continues to rotate, the soil on the annular discharge tray 2 will be thrown out under the action of centrifugal force.

[0039] Preferably, see Figure 2 and Figure 3 The lifting assembly 3 includes a support frame 32, a limit column 33, a threaded rod 34, a connecting plate 31 and a second drive motor 35. The support frame 32 and the limit column 33 are both vertically arranged on the top surface of the base 1. The threaded rod 34 can be rotatably limited and installed on the support frame 32. The connecting plate 31 is inserted on the limit column 33 and can also be lifted and rotated on the threaded rod 34. The rotating cleaning assembly 4 is arranged on the connecting plate 31 vertically to the base 1. The limit column 33 and the support frame 32 jointly limit the axial position of the connecting plate 31. The second drive motor 35 is arranged on the top of the support frame 32, and the driving end of the second drive motor 35 is axially connected to the threaded rod 34. After the second drive motor 35 is started, it drives the threaded rod 34 to rotate, so that the connecting plate 31 rises or falls along the threaded direction, thereby enabling the auger rod 41 on the rotating cleaning assembly 4 to move downward to perform soil cleaning operations.

[0040] Preferably, see Figure 2 In this embodiment, a stopper 36 is fixedly connected to the top of the limiting column 33 , and the limiting column 33 cooperates with the base 1 to axially limit the connecting plate 31 through the stopper 36 .

The third drive motor 42 is fixed to the connecting plate 31, and the driving end of the third drive motor 42 is axially connected to the auger rod 41. After the third drive motor 42 is started, it drives the auger rod 41 to rotate, and the soil in the building pile hole moves upward along the auger rod 41 to the annular discharge tray 2.

[0042] Preferably, see Figure 3In this embodiment, the second drive motor 35 and the third drive motor 42 are both fixedly connected to a support block 8 at the bottom, the support block 8 on the second drive motor 35 is connected and fixed to the top of the support frame 32, and the support block 8 on the third drive motor 42 is connected and fixed to the top of the connecting plate 31.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
