[0029] Understandably, referring to Figures 1 to 3The pipe coating device of this utility model includes a walking mechanism 100, a cleaning mechanism 200, and a coating mechanism 300. The walking mechanism 100 includes a support frame 110 and multiple sets of support components 120. The multiple sets of support components 120 are arranged at intervals along the length of the support frame 110. Each support component 120 includes multiple legs 130, which are arranged at intervals around the circumference of the support frame 110. Each leg 130 is rotatably connected to a roller 140, which can abut against the inner wall of the pipe. The support frame 110 is connected to a traction rope 111. The cleaning mechanism 200 includes a first driving component 210 and multiple vacuuming components 22. 0. The first driving component 210 is fixedly connected to the support frame 110. The first driving component 210 is used to drive multiple dust collection components 220 to rotate. The dust collection components 220 are used to suck up debris in the pipe. The painting mechanism 300 includes a paint bucket 310, a second driving component 320 and multiple brushes 330. The paint bucket 310 and the second driving component 320 are both fixed to the support frame 110. The paint bucket 310 is used to store paint. The lower end of the paint bucket 310 is provided with a discharge pipe 311. Paint can be output from the discharge pipe 311. The second driving component 320 is used to drive multiple brushes 330 to rotate so as to apply paint to the inner wall of the pipe.

[0030] Multiple support assemblies 120 are arranged along the length of the support frame 110. Each support assembly 120 includes multiple legs 130, which are spaced apart circumferentially along the support frame 110. Each leg 130 is rotatably connected to a roller 140, which abuts against the inner wall of the pipe. This allows the multiple legs 130 to work together to stabilize the support frame 110 within the pipe. By pulling the traction rope 111, the support frame 110 can move stably within the pipe. A first driving member 210 is fixedly connected to the support frame 110. The first driving member 210 drives multiple vacuuming assemblies 220 to rotate, enabling the vacuuming assemblies 220 to suck up debris from the inner wall of the pipe, keeping the inner wall of the pipe clean. The paint bucket 310 and the second drive unit 320 are both fixedly connected to the support frame 110. A discharge pipe 311 is provided at the lower end of the paint bucket 310, allowing the paint in the bucket to be discharged from the discharge pipe 311 and drip onto the inner wall of the pipe. Then, the second drive unit 320 drives multiple brushes 330 to rotate, enabling the brushes 330 to apply the dripping paint onto the inner wall of the pipe, thus replacing manual painting and improving painting efficiency. A cleaning mechanism 200 can remove debris from the pipe, keeping it clean and preventing paint from mixing with debris, thereby improving the quality of the paint application.

[0031] It should be noted that the output end of the first drive unit 210 protrudes from the support frame 110 and is connected to a bearing 112. The traction rope 111 is connected to the bearing 112 so that the traction rope 111 can pull the support frame 110 to slide inside the pipe, thus preventing the traction rope 111 from rotating or twisting.

[0032] Understandably, referring to Figure 2 and Figure 3 The paint bucket 310 is equipped with an adjusting seat 312, a baffle 313, and a first screw 314. The adjusting seat 312 is connected to the discharge pipe 311, the baffle 313 is slidably connected to the adjusting seat 312, and the first screw 314 is threadedly connected to the adjusting seat 312 and rotatably connected to the baffle 313. The adjusting seat 312 is connected to the output end of the discharge pipe 311, and the baffle 313 can slide on the adjusting seat 312 to open or close the discharge pipe 311. The first screw 314 is threadedly connected to the adjusting seat 312, and the baffle 313 is rotatably connected to the baffle 313. Rotating the first screw 314 drives the baffle 313 to slide on the adjusting seat 312, thereby allowing the baffle 313 to adjust the opening of the discharge pipe 311, facilitating the adjustment of the paint output speed, adapting to pipes of different diameters, and improving ease of use.

[0033] It should be noted that the adjusting seat 312 has a through hole, which is connected to the discharge pipe 311 so that the paint in the paint bucket 310 can flow through the discharge pipe 311 and the through hole in sequence.

[0034] Understandably, referring to Figure 2 and Figure 4 The dust collection assembly 220 includes a housing 221, a fan 222, and a waste bag 223. The fan 222 is fixedly connected to the housing 221, and the housing 221 has an opening 224. The waste bag 223 is detachably connected to the opening 224. The fan 222 drives airflow from the opening 224 into the waste bag 223. By driving airflow from the fan 222 into the opening 224, the airflow can carry debris into the waste bag 223, thereby sucking up debris from the pipe, keeping the pipe clean, preventing debris from mixing with paint, and improving the quality of the coating.

[0035] The waste bag 223 can be fixed to the opening 224 by means of adhesive, buckle, etc., so as to facilitate the cleaning of debris inside the waste bag 223 and improve the ease of use of the vacuuming component 220.

[0036] Specifically, refer to Figure 1 and Figure 2The cleaning mechanism 200 also includes multiple first telescopic rods 230. One end of each first telescopic rod 230 is connected to the first drive member 210, and the other end is connected to the housing 221. Each first telescopic rod 230 corresponds one-to-one with a vacuuming assembly 220. The multiple first telescopic rods 230 are arranged at intervals along the circumference of the support frame 110. One end of each first telescopic rod 230 is connected to the first drive member 210, and the other end is connected to the housing 221. The position of the housing 221 can be adjusted by the first telescopic rods 230, thereby allowing the vacuuming assembly 220 to adapt to the inner diameter of the pipe, facilitating the adaptation of the vacuuming assembly 220 to the size of the pipe, and improving the effect of collecting debris.

[0037] Understandably, referring to Figure 1 and Figure 2 The coating mechanism 300 also includes multiple second telescopic rods 340. One end of each second telescopic rod 340 is connected to a second driving member 320, and the other end is connected to a brush 330. Each second telescopic rod 340 corresponds to a brush 330. The multiple second telescopic rods 340 are arranged at intervals along the circumference of the support frame 110. One end of each second telescopic rod 340 is connected to the second driving member 320, and the other end is connected to the brush 330. By setting the second telescopic rods 340, the position of the brush 330 can be adjusted so that the brush 330 can abut against the inner wall of the pipe, thereby adapting to pipes of different inner diameters and enabling the brush 330 to evenly coat the inner wall of the pipe, improving the applicability of the pipe coating device.

[0038] Specifically, refer to Figure 1 and Figure 5 A mounting base 341 is provided at the end of the second telescopic rod 340 opposite to the second driving member 320. The brush 330 is inserted into the mounting base 341, and a second bolt 342 is threadedly connected to the side wall of the mounting base 341. The second bolt 342 can abut against the brush 330. The mounting base 341 is fixedly connected to the end of the second telescopic rod 340 opposite to the second driving member 320. The brush 330 can be inserted into the mounting base 341, and the second bolt 342 passes through the side wall of the brush 330. The second bolt 342 is threadedly connected to the side wall of the mounting base 341 so that the second bolt 342 can abut against the brush 330, thereby fixing the brush 330 to the mounting base 341, facilitating the replacement of the brush 330 and improving the convenience of use.

[0039] It should be noted that loosening the second bolt 342 allows it to separate from the brush 330, enabling the brush 330 to be removed from the mounting base 341. Then, a new brush 330 is inserted into the mounting base 341, and the second bolt 342 is tightened to press the brush 330 firmly into the mounting base 341. This facilitates the replacement of the brush 330 and improves ease of use.

[0040] Understandably, referring to Figure 2 and Figure 6 The support leg 130 includes a fixed base 131 and a movable rod 132. The fixed base 131 is fixedly connected to the support frame 110, and the movable rod 132 is slidably connected to the fixed base 131. The fixed base 131 is threadedly connected to a third screw 133. The movable rod 132 has multiple positioning holes 134 along its length, and the third screw 133 can extend into the positioning holes 134. A roller 140 is connected to the movable rod 132. The fixed base 131 is fixedly connected to the support frame 110, and the movable rod 132 is slidably connected to the fixed base 131 so that the movable rod 132 can slide along the length direction of the fixed base 131. Multiple positioning holes 134 are arranged at intervals along the length direction of the movable rod 132. The third bolt is threadedly connected to the fixed base 131 so that the third screw 133 can extend into the fixed base 131 and can pass through the positioning hole 134, thereby facilitating the positioning of the movable rod 132 on the fixed base 131 and improving the adjustment convenience of the support leg 130.

[0041] It should be noted that by loosening the third screw 133 so that it can disengage from the positioning hole 134, the movable rod 132 can slide into or out of the fixed seat 131, making it convenient to adjust the length of the support leg 130. Then, by rotating the third screw 133, the third screw 133 can be screwed into the positioning hole 134, thereby locking the length of the support leg 130 and improving the ease of adjustment of the support leg 130.

[0042] Specifically, refer to Figure 1 and Figure 6 The roller 140 is provided with a connecting seat 141, and the connecting seat 141 is provided with a guide rod 142. The guide rod 142 is slidably connected to the movable rod 132. A limit block 143 is provided at the end of the guide rod 142 away from the connecting seat 141. The limit block 143 can abut against the movable rod 132. A spring 144 is provided between the movable rod 132 and the connecting seat 141. The spring 144 is used to drive the connecting seat 141 to move away from the movable rod 132. The roller 140 is provided with a connecting seat 141, and the guide rod 142 is fixedly connected to the connecting seat 141 and can slide on the movable rod 132. By providing a limit block 143 at the end of the guide rod 142 away from the connecting seat 141, the limit block 143 can limit the position of the guide rod 142, thereby preventing the guide rod 142 from sliding out of the movable rod 132 and improving the positional stability of the roller 140.

[0043] In addition, spring 144 is sleeved on guide rod 142. One end of spring 144 abuts against connecting seat 141 and the other end abuts against movable rod 132, so that spring 144 can drive connecting seat 141 to move away from movable rod 132, thereby enabling roller 140 to abut against the inner wall of pipe, thus adapting to changes in the inner diameter of pipe, allowing roller 140 to keep in close contact with the inner wall of pipe, improving the movement stability of traveling mechanism 100 and improving the quality of coating.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
