The two ends of the transverse gas pipe are respectively provided with nozzles in opposite directions. The direction of the nozzle at the end is obliquely downward. The lower end of the main gas pipe is connected to the rotary joint. However, there are certain inconveniences in actual use. Because the length of the transverse gas pipe is fixed in the technical solution, it is difficult to adapt to the sediment cleaning work of cast-in-place pile holes of different diameters, and the applicability is poor, which is not conducive to use.

DETAILED DESCRIPTION

[0023] The following description is used to disclose the utility model so that those skilled in the art can realize the preferred embodiments in the following description of the utility model, and those skilled in the art can think of other obvious variants. Embodiment one

[0024] Please refer to Figures 1-4 The utility model provides a kind of rotary drilling pile hole bottom sludge cleaning device, including transverse pipe 1, the joint pipe 2 being fixedly communicated with the top of the outer peripheral surface of transverse pipe 1, the main gas pipe 3 being fixedly communicated with the top of joint pipe 2, the movable pipe 10 being slidably inserted in the position of the both sides of transverse pipe 1 and the adjusting air outlet mechanism acting on movable pipe 10;

[0025] Adjusting air outlet mechanism includes extension assembly and adjusting assembly;

[0026] When the device is placed in different hole diameters of rotary drilling pile hole to clean inside, the total length between transverse pipe 1 and two movable pipes 10 can be adjusted by the action of extension assembly, so that the sludge cleaning work of different diameters of rotary drilling pile hole can be facilitated, and the activity range of air flow can be enlarged in the cleaning process by adjusting assembly, so that the cleaning effect of rotary drilling pile hole is improved.

[0027] Please refer to Figures 1-4The extension assembly comprises two fixing bases 4 fixed to the outer circumferential surface of the main pipe 3, a motor 6 fixed to the top of one of the fixing bases 4, a threaded rod 5 rotatably connected to one end of the middle position of the two fixing bases 4, a threaded sleeve 8 threadedly connected to the outer circumferential surface of the threaded rod 5, a guide component acting on the threaded sleeve 8, and connecting rods 9 hingedly connected to the two sides of the threaded sleeve 8, the bottom of the connecting rod 9 being hingedly connected to one side of the outer circumferential surface of the adjacent movable pipe 10, and one end of the threaded rod 5 penetrating through the adjacent fixing base 4 and being fixed to the output end of the motor 6;

[0028] By starting the motor 6, the threaded rod 5 can be rotated, and the guide component can limit the threaded sleeve 8, so that the threaded sleeve 8 can only slide in the vertical direction, thereby driving the threaded sleeve 8 to move in the vertical direction when the threaded rod 5 rotates, so that the connecting rod 9 changes in angle and changes in length in the horizontal direction, so that the movable pipe 10 can move towards each other or away from each other, so that the total length between the movable pipe 10 and the cross pipe 1 can be adjusted to adapt to the size of the bored pile hole of the corresponding diameter, thereby improving the applicability of the device.

[0029] Please refer to Figures 1-4 The guide component comprises a contact groove 19 penetratingly provided at the position of the threaded sleeve 8 away from the threaded rod 5, and a positioning rod 7 penetratingly inserted into the contact groove 19, the upper and lower ends of the positioning rod 7 being fixed to the surface of the adjacent fixing base 4;

[0030] Due to the contact limitation of the inner wall of the contact groove 19 to the positioning rod 7, the threaded sleeve 8 can only slide vertically along the outer circumferential surface of the positioning rod 7, so that the threaded sleeve 8 can only move in the vertical direction under the drive of the threaded rod 5, thereby limiting the threaded sleeve 8.

[0031] Please refer to Figures 1-4 The adjusting assembly comprises a gas guide pipe 14 fixedly connected to one side of the movable pipe 10, a corrugated pipe 15 fixedly connected to one side of the gas guide pipe 14, a gas outlet nozzle 16 fixedly connected to one side of the corrugated pipe 15 and arranged in an inclined manner, and a hydraulic cylinder 17 mounted to the bottom of the outer circumferential surface of the gas guide pipe 14, the output end of the hydraulic cylinder 17 being rotatably connected to the adjacent gas outlet nozzle 16;

[0032] Due to the gas flow from the main pipe 3 through the joint pipe 2 to the inside of the horizontal pipe 1, the gas can flow from the movable pipe 10 through the gas guide pipe 14 and the bellows pipe 15 into the inside of the gas outlet nozzle 16 and be discharged from the gas outlet nozzle 16, so as to realize the cleaning work of the bored pile hole, and through the extension and contraction movement of the output end of the hydraulic cylinder 17, the gas outlet nozzle 16 can swing along a certain angle under the connection of the bellows pipe 15, so as to expand the range of the gas flow discharged from the gas outlet nozzle 16, thereby improving the cleaning effect of the bored pile hole. Example two

[0033] With reference to Figures 1-4 As shown, the adjusting gas outlet mechanism further comprises a sealing component acting on the horizontal pipe 1, the sealing component comprising a threaded section 11 arranged on the outer circumferential surface of the movable pipe 10 near the side of the horizontal pipe 1, a rotating sleeve 12 threadedly connected at the position of the threaded section 11, a sealing ring 13 fixed on one side of the rotating sleeve 12, and a ring groove 18 opened on both sides of the horizontal pipe 1.

[0034] After the total length between the horizontal pipe 1 and the movable pipe 10 is adjusted, the rotating sleeve 12 is rotated, so as to slide along the horizontal direction under the cooperation of the threaded structure between the rotating sleeve 12 and the adjacent movable pipe 10, so that the sealing ring 13 can be embedded into the inside of the adjacent ring groove 18, thereby playing a sealing role from both sides of the horizontal pipe 1, avoiding the gas leakage from both sides of the horizontal pipe 1.
