Description

Technical Field

[0001] The utility model relates to the technical field of inner wall cleaning of pipe piles, in particular to a cleaning device for the inner wall of a pipe pile. Background Art

[0002] In the process of civil engineering construction, pipe piles and pile caps need to be arranged. In the prior art, hollow pipe piles are usually arranged, and then the pipe piles and pile caps are cast in one piece.

[0003] During the actual pouring process, the inner wall of the pipe pile needs to be cleaned. Since a large amount of mud or concrete sand and gravel will adhere to the inner wall of the pipe pile during installation, it needs to be cleaned with a brush.

[0004] During the cleaning process, the existing technology usually uses manpower to rotate the brush for cleaning. During the cleaning process, cement slurry, concrete interface agent or micro-expansive concrete and other spray liquids are sprayed. However, during actual cleaning, the mud on the inner wall mostly adheres to the concrete, making it difficult to clean the inner wall efficiently. Traditional rotary scraping will cause rotational friction between the tool and the concrete residue, and the cleaning efficiency is low. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] A cleaning device for the inner wall of a pipe pile is installed in the pipe pile 1. The cleaning device comprises a rotating pipe 5 and an upper frame 2.

[0025] The upper frame 2 is provided with a driving assembly for driving the rotating tube 5 to rotate and lift, and the driving assembly includes a driven gear 7 and a driving gear 8. A screw rod 6 is provided at the upper end of the rotating tube 5. The upper end of the screw rod 6 slides through the upper frame 2, and the upper end of the screw rod 6 is threadedly rotatably sleeved on the driven gear 7. The driven gear 7 is meshed and connected with the driving gear 8. A motor for driving the driving gear 8 to rotate is provided on the upper frame 2.

[0026] The motor drives the driving gear 8 to rotate, which in turn drives the driven gear 7 to rotate, so that the screw rod 6 rises under the rotation of the thread, and synchronously pulls the rotating tube 5 to rotate and rise.

[0027] A sleeve 3 is fixedly sleeved on the rotating tube 5, and a brush 16 distributed in a circumferential array is arranged on the arc outer wall of the sleeve 3. A conical tube is arranged on the outer wall of the middle section of the rotating tube 5, and a nozzle 11 of an external material pump is arranged on the conical tube. The inner cavity of the folding ring 18 is connected to the inner cavity of the rotating tube 5.

[0028] The nozzle 11 is used to spray cement paste, concrete interface agent or micro-expansion concrete on the pipe wall to facilitate the removal of residues. When the rotating pipe 5 rises and rotates, the brush 16 rotates to clean the pipe wall.

[0029] The lower end of the rotating tube 5 is provided with a bottom plate 4, and a circular folding ring 18 is provided on the bottom plate 4. The upper end of the circular folding ring 18 is provided with a circular knife plate 17 that fits the inner wall of the pipe pile 1. The lower end of the upper frame 2 is provided with a stud 9. A piston 15 is provided in the inner cavity of the rotating tube 5. A screw tube 10 that drives the piston 15 to rise and fall is sleeved on the stud 9. A boss 19 is provided on the upper end of the rotating tube 5. The lower end of the screw 6 is fixed on the boss 19. The boss 19 is provided with arc-shaped rotating grooves 12 distributed in a circumferential array, and a pair of connecting rods 13 are provided at the upper end of the piston 15. The connecting rods 13 slide along the arc-shaped rotating grooves 12 and extend to the outside of the rotating tube 5. The upper end of the spiral tube 10 is threadedly installed on the stud 9, and a gap is left between the upper end of the spiral tube 10 and the upper frame 2. The upper end of the connecting rod 13 is provided with a pressing plate 14 sleeved on the screw 6, and the lower end of the spiral tube 10 is rotated and pressed on the upper end surface of the pressing plate 14.

[0030] During the cleaning process, when encountering firmly bonded concrete residues, if the existing rotation cleaning is adopted to make the circular blade plate 17 rotate and scrape off the concrete residues, the circular blade plate 17 will continue to rotate and rub against the concrete residues at high speed, resulting in low cleaning efficiency.

[0031] Therefore, the present application designs the rotation of the screw tube 10 on the stud 9. Through the threaded rotation of the screw tube 10, the purpose of pressing down the pressure plate 14 is achieved, and the piston 15 is synchronously driven to move down to achieve the purpose of squeezing the inner cavity of the rotating tube 5. The internal pressure of the rotating tube 5 increases, driving the inner cavity of the folding ring 18 to expand, and then the circular knife plate 17 is squeezed and lifted under the action of pressure. Since the circular knife plate 17 fits the pipe wall, the adhered concrete residues are squeezed and scraped off in the vertical direction, avoiding the continuous friction caused by the rotation and lifting, improving the cleaning efficiency and protecting the life of the cleaning device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
