[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] In order to solve the technical problem of low efficiency that workers adjust each support rod one by one, the utility model provides a grinding tool for the inner wall of a pipeline, which can improve the processing efficiency.

[0023] It should be noted that the grinding tool for the inner wall of a pipe described in the utility model is used for but not limited to pipes, etc. For the convenience of explanation, in the utility model, only an example of a grinding tool for the inner wall of a pipe being applied to a pipe is used for explanation. The principle of applying a grinding tool for the inner wall of a pipe to other types of equipment is essentially the same as the principle applied to pipes, and will not be repeated here.

[0024] See also Figure 1 - Figure 3 ,in Figure 1 This is a structural schematic diagram of a grinding tool for the inner wall of a pipe in one embodiment of the utility model. The grinding tool for the inner wall of a pipe includes a grinding member 1 and a driving member 2. The grinding member 1 includes a rotating drum 11, a plurality of springs 12 and a plurality of grinding rods 13. One end of the rotating drum 11 is provided with a plurality of channels 111 along the circumferential direction, and one end of the channel 111 extends toward the axial direction of the rotating drum 11. One end of the grinding rod 13 passes through the channel 111 and is hinged to the inner wall of the rotating drum 11. The two ends of the spring 12 are respectively hung on the inner wall of the rotating drum 11 and the grinding rod 13 so that the grinding rod 13 is always in an open state. The driving member 2 is used to drive the rotating drum 11 to rotate.

[0025] In this embodiment, through the setting of the channel 111, an adjustment mechanism for the distance between the polishing rods 13 is formed, so that the polishing rods 13 are suitable for pipes with different diameters. Further, through the setting of the spring 12, after each polishing rod 13 is extended into the pipes with different diameters, each polishing rod 13 can automatically abut against the inner wall of the pipe under the tension of the spring 12, and the staff does not need to manually adjust the support rods one by one, which effectively improves the processing efficiency.

[0026] First, the staff holds each grinding rod 13 so that each grinding rod 13 is retracted along the length direction of the channel 111 to facilitate insertion into the pipe; then, the staff releases their hands, and each grinding rod 13 opens and abuts against the inner wall of the pipe under the action of its own spring 12; finally, the driving member 2 is started, and the rotating drum 11 drives each grinding rod 13 to rotate together, and at the same time, the grinding rod 13 is operated to move along the length direction of the pipe until the grinding of the inner wall of the pipe is completed.

[0027] In one embodiment, see Figure 1 - Figure 2 A grinding plate 14 is hingedly connected to the end of the grinding rod 13 away from the rotating drum 11.

[0028] In one embodiment, see Figure 1 - Figure 2, one side of the grinding plate 14 is fixedly connected with a grinding brush 141.

[0029] In this embodiment, the grinding brush 141 matches the grinding plate 14 and both are square structures. The grinding brush 141 is fixedly connected to the grinding plate 14 to prevent the grinding brush 141 from falling off during the grinding process. When the grinding brush 141 needs to be replaced due to aging, the hinge connection between the grinding plate 14 and the grinding rod 13 is directly removed, so that the grinding brush 141 and the grinding plate 14 are replaced together.

[0030] In one embodiment, please refer to Figure 1 - Figure 3 , one end of the rotating cylinder 11 far from the channel 111 is fixedly connected with an extension rod 15.

[0031] In this embodiment, the function of the extension rod 15 is to facilitate the grinding member 1 to extend into the pipeline.

[0032] In one embodiment, please refer to Figure 1 - Figure 3 , the driving member 2 is a motor 21, and one end of the extension rod 15 away from the rotating cylinder 11 is connected to the motor 21.

[0033] In this embodiment, the motor 21 adopts a micro servo motor, which is light in weight and convenient for the staff to hold and operate.

[0034] In one embodiment, please refer to Figure 1 - Figure 2 , a handle 3 is sleeved on the outer surface of the motor 21.

[0035] In this embodiment, the function of the handle 3 is to facilitate the staff to hold and operate.

[0036] In one embodiment, please refer to Figure 1 - Figure 2 , a switch 4 is installed on the outer surface of the handle 3, and the switch 4 is electrically connected to the motor 21.

[0037] In this embodiment, the function of the switch 4 is to facilitate the staff to manually control the opening and closing of the motor 21.

[0038] In one embodiment, please refer to Figure 1 - Figure 3 , a protective cover 16 is rotatably sleeved on the extension rod 15, and the protective cover 16 is fixedly connected to the handle 3.

[0039] In this embodiment, the function of the protective cover 16 is to improve the stability of the extension rod 15.

[0040] In one embodiment, please refer to Figure 1 - Figure 2 , anti-slip lines 161 are formed on the outer surface of the protective cover 16.

[0041] In this embodiment, the anti-slip pattern 161 serves to facilitate the staff to grasp.

[0042] In one embodiment, see Figure 1 - Figure 3 The channel 111 is square, the polishing rod 13 is cube-shaped, and the width of the channel 111 is the same as the width of the polishing rod 13 .

[0043] In this embodiment, the width of the channel 111 is the same as the width of the polishing rod 13, so that the polishing rod 13 can only move axially toward the drum 11 along the length direction of the channel 111, thereby avoiding misalignment of the polishing rod 13 and achieving the opening or closing of the polishing rods 13, thereby being suitable for pipes of different diameters.

[0044] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0045] First, the staff sprays the polishing agent into the pipeline; secondly, the staff holds each polishing rod 13, so that each polishing rod 13 is retracted along the length direction of the channel 111 to facilitate insertion into the pipeline; then, the hands are released, and each polishing rod 13 opens under the action of its own spring 12, and each polishing brush 141 abuts against the inner wall of the pipeline; finally, the switch 4 is manually operated to start the motor 21, and the movable end of the motor 21 drives the extension rod 15, the rotating drum 11 and each polishing rod 13 to rotate in turn. At the same time, the handle 3 is manually operated to move the polishing rod 13 along the length direction of the pipeline to polish the inner wall of the entire pipeline until the polishing of the inner wall of the pipeline is completed. The device does not require the staff to manually adjust the support rods one by one, which effectively improves the processing efficiency.

[0046] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
