[0017] like Figures 1-3 As shown, this utility model discloses an automatic mobile multi-functional dust removal and spraying device for pipeline 1, including a front-end operation section and a rear-end air compressor unit section. The front-end operation section is set inside the pipeline 1 during operation and is used to remove rust, slag and spray the inner wall of the pipeline 1. The rear-end air compressor unit section is located outside the pipeline 1 and is used to provide power for the front-end operation section to remove slag and spray the device during operation.

[0018] The front-end operation section includes the equipment body 2, a disc-shaped rotating head 9 located at the front of the equipment body 2, a motor located inside the equipment body 2 and connected to the rotating head 9 for transmission, and three functional devices arranged in a "V" shape on the rotating head 9. The functional devices are, in order, a wire brush head 8, a dust and slag suction pipe 6, and a paint spraying port 7. The wire brush head 8 is located on the rear side in the direction of the rotation axis, the paint spraying port 7 is located on the front side, and the dust and slag suction pipe 6 is located between the wire brush head 8 and the paint spraying port 7. The wire brush head 8 is in contact with the inner wall of the pipe 1, and the dust and slag suction pipe 6 and the paint spraying port 7 are 3cm away from the inner wall of the pipe 1.

[0019] The wire brush head 8, the dust and slag suction pipe 6, and the paint spraying port 7 are connected to the rotating head 9 through a telescopic structure of "mother and son rods", and their lengths can be adjusted according to different pipe diameters.

[0020] The equipment body 2 is equipped with a traveling mechanism on its exterior. The traveling mechanism includes three front pulleys 3 installed at the front end of the equipment body 2 and arranged in a "V" shape around the axial direction of the equipment body 2, and a support pulley 4 located at the bottom of the rear end of the equipment body 2. The front pulleys 3 and the support pulley 4 are supported on the inner wall of the pipeline 1 to be constructed. The front pulleys 3 and the support pulley 4 are respectively connected to the equipment body 2 through connecting rods. The connecting rods are hinged to the equipment body 2 through pins, and a spring device 5 is provided between the connecting rods and the equipment body 2. Before the front working part is placed inside the pipeline 1, the spring device 5 is contracted by pressing the front pulleys 3, allowing the equipment body 2 to enter the pipeline 1. Under the action of the spring device 5, the front pulleys 3 and the support pulley 4 abut against the inner wall of the pipeline 1.

[0021] The front pulley 3 is rotatably mounted in the base 23. A micro motor 24 is mounted outside the base 23. The front pulley 3 is connected to the micro motor 24 for transmission. The micro motor 24 can be mounted on two front pulleys 3 or on three front pulleys 3 respectively, depending on the power requirements.

[0022] The device body 2 is equipped with a wireless receiver module 11, which is electrically connected to the motor and the micro motor 24 respectively, and is used to receive wireless signals and control the start and stop of the motor and the micro motor 24. The device body 2 is also equipped with a battery 10, which supplies power to the motor and the micro motor 24.

[0023] During operation, turn on the power switch of the front-end working section, and use the wireless remote control to control the micro motor 24 to move the equipment body 2 to the front end of the pipe 1. Turn on the motor switch with the remote control to make the rotating head 9 drive the wire brush head 8, the dust and slag suction pipe 6 and the paint spraying port 7 to rotate synchronously at high speed. Use the wireless remote control to control the equipment body 2 to slowly retreat. During the retreat, the wire brush head 8 cleans the inner wall of the pipe 1, the dust and slag suction pipe 6 sucks away the slag in the pipe 1, and the paint spraying port 7 simultaneously performs high-pressure spraying on the cleaned pipe 1. Until it retreats to the end of the pipe 1, turn off all power switches, and the first spraying operation is completed.

[0024] If multiple coats of paint are required, after the first coat of paint in pipe 1 has dried, remove the wire brush head 8, turn off the dust extraction switch, and repeat the above steps to apply the second coat of paint.

[0025] The rear air compressor unit includes a winding reel 15 located at the front end of the body 14, which is used to retract the paint delivery hose 12 connected to the paint spraying port 7 and the dust and slag suction hose 13 connected to the dust and slag suction port 6. A handle is installed on the outside of the winding reel 15 for rotating the winding reel 15 to retract the paint delivery hose 12 and the dust and slag suction hose 13.

[0026] An air compressor unit 17 is located in the middle of the machine body 14. The air compressor unit 17 is controlled by a dual valve and operates through an external power supply. The air compressor unit 17 is connected to a slag collection box 21 and a paint delivery pipe 19 to a paint box 16, which is used to control the dust collection function and the spraying function.

[0027] The paint tank 16 has a filling port 18, through which the mixed paint is poured into the paint tank 16. The slag collection box 21 is equipped with a detachable slag collection hopper 22 for easy cleaning of waste.

[0028] The usage method is as follows: S1: First, fix the pipe 1, which needs to be coated with anti-corrosion spraying on the inner wall, to the ground, and pour the prepared coating into the coating tank 16 through the filling port 18.

[0029] S2: By pressing the front pulley 3 and the support pulley 4, place the equipment body 2 inside the pipe 1, adjust the angle of the equipment body 2, and ensure that the support pulley 4 is located at the bottom inside the pipe 1.

[0030] S3: Turn on the front-end operation equipment switch, and use the remote control to control the micro motor 24 to drive the equipment body 2 to move inside the pipe 1 to the front port of the pipe 1. When the equipment body 2 moves, manually rotate the winding reel 15 to release the flexible hose and lay the pipe as the equipment body 2 moves.

[0031] S4: Adjust the lengths of the wire brush head 8, the dust and slag suction pipe 6, and the paint spraying nozzle 7 to ensure that the wire brush head 8 is in contact with the inner wall of the pipe 1, the dust and slag suction pipe 6 and the paint spraying nozzle 7 are 3cm away from the inner wall of the pipe 1, and ensure that the paint spraying nozzle 7 is at the front end, the wire brush head 8 is at the rear, and the dust and slag suction pipe 6 is between the wire brush head 8 and the paint spraying nozzle 7.

[0032] S5: The motor is controlled by a wireless remote control, which drives the rotating head 9 to rotate. The wire brush head 8, the dust and slag suction pipe 6, and the paint spraying port 7 also rotate at high speed in sync.

[0033] S6: Turn on switch 17 of the air compressor unit. At this time, the front-end rust removal and spraying work has started.

[0034] S7: Control the equipment body 2 to slowly move backward in the pipe 1 via remote control. At this time, slag removal, slag suction and dust removal and spraying operations are carried out simultaneously.

[0035] S8: When the equipment inside pipe 1 reaches the end of pipe 1, the power can be turned off, and the first coat of anti-corrosion coating inside pipe 1 has been applied.

[0036] S9: If the anti-corrosion coating inside pipe 1 needs to be sprayed twice, remove the wire brush head 8 before spraying and close the valve switch of the air compressor unit 17 that controls the suction of slag and dust.

[0037] S10: After the first coat of anti-corrosion coating inside pipe 1 has dried, repeat steps S1-S8. For the second coat, only turn on the air compressor equipment that controls the spraying to carry out the spraying operation, without scraping off slag or vacuuming to remove dust. S11: When applying anti-corrosion coating to the inner wall of a large number of pipes in the later stage, the first and second coats can be applied alternately by repeating steps S1-S10.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
