Technical Field

[0001] This utility model relates to the field of pipe inner wall polishing and cleaning technology, specifically a pipe inner wall polishing machine. Background Technology

[0002] Currently, in the prior art, when polishing and cleaning the inner wall of pipes, most existing pipe inner wall polishing equipment requires hand operation and cannot move autonomously on the inner wall of the pipe to complete the polishing and cleaning; moreover, it is not convenient to adjust according to the usage requirements of pipes with different inner diameters; nor is it convenient to change direction and turn inside non-straight pipes, and cannot well meet the usage requirements of pipe inner wall polishing and cleaning. Therefore, this application proposes a pipe inner wall polishing machine. Utility Model Content

[0003] To overcome the technical deficiencies in the prior art and effectively solve the technical problems in the background art, this utility model provides the following technical solution:

[0004] A pipe inner wall polishing machine includes a cylindrical housing, two cylindrical housings arranged symmetrically front to back, connected by a horizontally rotatable connecting part, at least three sets of telescopic and adjustable walking components and support components evenly distributed along the circumference on the outer sides of the two cylindrical housings, as well as a camera, a distance sensor and a lighting lamp, wherein the front end of the cylindrical housing located on the front side is rotatably connected to a bidirectional reciprocating component, and polishing brushes are respectively provided at the two ends of the bidirectional reciprocating component with opposite directions of movement;

[0005] It also includes a wireless controller and a battery, which are respectively disposed on the inner wall of the cylindrical housing.

[0006] As a preferred technical solution of this utility model, the walking assembly includes an electric telescopic rod, a U-shaped mounting base, walking wheels, and a walking motor. The electric telescopic rod is disposed on the outside of the cylindrical shell. A U-shaped mounting base is disposed on the outer end of the electric telescopic rod. The two arms of the U-shaped mounting base are rotatably connected to the walking wheels via a rotating shaft. A walking motor is disposed on the outside of the U-shaped mounting base. The output shaft of the walking motor is fixedly connected to one end of the rotating shaft.

[0007] As a preferred embodiment of this utility model, the support assembly includes an electric telescopic rod II and an anti-slip rubber block. The electric telescopic rod II is disposed on the outside of the cylindrical shell, and an anti-slip rubber block is disposed on the outer end of the electric telescopic rod II.

[0008] As a preferred embodiment of this utility model, the bidirectional reciprocating assembly includes a U-shaped bracket, a guide rod, a bidirectional lead screw, a slider, a reciprocating motor, a reciprocating battery, and a wireless control switch. A polishing motor is installed inside the cylindrical housing located at the front. The output shaft of the polishing motor passes through the front wall of the cylindrical housing and is fixedly connected to the rear side of the horizontal end of the U-shaped bracket. The bidirectional lead screw is rotatably connected between the two arms of the U-shaped bracket via bearings. The guide rod is fixedly installed between the two arms of the U-shaped bracket. The bidirectional lead screw and the guide rod are parallel to each other. There are two sliders. The two ends of the bidirectional lead screw with opposite threads are threadedly connected to the threaded holes on the sides of the two sliders, respectively. The guide rod is slidably connected to the sliding holes on the sides of the two sliders, respectively. Polishing brushes for polishing the inner wall of the pipe are respectively provided on the front sides of the two sliders via L-shaped connecting rods. The distance between the two polishing brushes is greater than the length of the reciprocating motor plus the U-shaped bracket. The reciprocating motor is fixedly installed on the outside of one arm of the U-shaped bracket, and the output shaft of the reciprocating motor is fixedly connected to one end of the bidirectional lead screw.

[0009] Compared with the prior art, the beneficial effects of this utility model are: this pipe inner wall polishing machine does not require hand operation and can autonomously walk on the inner wall of the pipe to complete polishing and cleaning; it is easy to adjust according to the usage requirements of pipes with different inner diameters; it is easy to change direction and turn inside non-straight pipes, and can well meet the usage requirements of pipe inner wall polishing and cleaning.

[0010] Specifically, the telescopic adjustment of the electric telescopic rod drives the telescopic adjustment of the U-shaped mounting base and the traveling wheels to adapt to the needs of pipes with different inner diameters. The traveling motor drives the rotation of the shaft and the traveling wheels, enabling the equipment to move autonomously inside the pipe. When a turn is required, the traveling motor on one side can be stopped to facilitate the equipment's turning.

[0011] The extension and retraction adjustment of the electric telescopic rod 2 drives the extension and retraction adjustment of the anti-slip rubber block to adapt to the needs of pipes with different inner diameters. The extension and retraction of the three sets of electric telescopic rod 2 drives the extension and retraction of the three sets of anti-slip rubber blocks. When support and fixation are required, the inner wall of the pipe is supported and fixed to stabilize the equipment and carry out polishing operations.

[0012] By driving two sliders to move towards or away from each other using a reciprocating motor, two L-shaped connecting rods and two polishing brushes can also move towards or away from each other. This allows the distance between the two polishing brushes to be adjusted according to the needs of pipes with different inner diameters, so that they can contact and squeeze the inner wall of the pipe for polishing, and retract to avoid contact with the inner wall of the pipe when movement is required. The inner wall of the pipe can be polished by rotating the bidirectional reciprocating assembly and the two polishing brushes driven by the polishing motor.

[0013] The camera, distance sensor, and lighting facilitate illumination and monitoring during operation. Attached Figure Description

[0023] Furthermore, such as Figure 1 As shown, the walking assembly 3 includes an electric telescopic rod 31, a U-shaped mounting base 32, walking wheels 33, and a walking motor 34. The electric telescopic rod 31 is fixedly installed on the outside of the cylindrical housing 1 with bolts and nuts. The U-shaped mounting base 32 is fixedly installed on the outer end of the electric telescopic rod 31 with bolts and nuts. The two arms of the U-shaped mounting base 32 are rotatably connected to the walking wheels 33 through a rotating shaft and bearings. The walking motor 34 is fixedly installed on the outside of the U-shaped mounting base 32 with bolts and nuts. The output shaft of the walking motor 34 is fixedly connected to one end of the rotating shaft with bolts and nuts. In use, the telescopic adjustment of the electric telescopic rod 31 drives the telescopic adjustment of the U-shaped mounting base 32 and the walking wheels 33 to adapt to the needs of pipes with different inner diameters. The walking motor 34 drives the rotation of the rotating shaft and the walking wheels 33 to move the equipment inside the pipe. When a turn is required, the walking motor 34 on one side can be stopped to facilitate the turning of the equipment. The principle is a mature existing technology and will not be described in detail here.

[0024] Furthermore, such as Figure 1As shown, the support assembly 4 includes an electric telescopic rod 41 and an anti-slip rubber block 42. The electric telescopic rod 41 is fixedly installed on the outside of the cylindrical shell 1 by bolts and nuts. The anti-slip rubber block 42 is fixedly installed on the outer end of the electric telescopic rod 41 by bolts and nuts. In use, the extension and retraction of the electric telescopic rod 41 drives the extension and retraction of the anti-slip rubber block 42 to adapt to the needs of pipes with different inner diameters. The extension and retraction of the three sets of electric telescopic rods 41 drives the extension and retraction of the three sets of anti-slip rubber blocks 42. When support and fixation are required, the inner wall of the pipe is supported and fixed to stabilize the equipment and perform polishing operations.

[0025] Furthermore, such as Figure 3 As shown, the bidirectional reciprocating assembly 6 includes a U-shaped bracket 61, a guide rod 62, a bidirectional lead screw 63, a slider 64, a reciprocating motor 65, a reciprocating battery 66, and a wireless control switch 67. A polishing motor 5 is fixedly installed inside the cylindrical housing 1 located at the front by bolts and nuts. The output shaft of the polishing motor 5 passes through the front side of the inner wall of the cylindrical housing 1 and is fixedly connected to the rear side of the horizontal end of the U-shaped bracket 61 by bolts and nuts. The bidirectional lead screw 63 is rotatably connected between the two arms of the U-shaped bracket 61 via bearings. The guide rod 62 is fixedly installed by bolts and nuts. The bidirectional lead screw 63 and guide rod 62 are parallel to each other and mounted between the two arms of the U-shaped bracket 61. There are two sliders 64. The two ends of the bidirectional lead screw 63 with opposite threads are threadedly connected to the threaded holes on the sides of the two sliders 64. The guide rod 62 is slidably connected to the sliding holes on the sides of the two sliders 64. L-shaped connecting rods 7 are respectively provided on the front side of the two sliders 64. The vertical ends of the two L-shaped connecting rods 7 are welded and fixedly connected to the front side of the sliders 64. The outer edges of the horizontal ends of the two L-shaped connecting rods 7 facing outwards are respectively provided with… Polishing brushes 8 are used for polishing the inner wall of pipes. The distance between the two polishing brushes 8 is greater than the length of the reciprocating motor 65 plus the U-shaped bracket 61 (so that the polishing brushes 8 can contact and polish the inner wall of the pipe, and can also play an auxiliary protective role to prevent the reciprocating motor 65 from contacting and colliding with the inner wall of the pipe and causing damage). The reciprocating motor 65 is fixedly installed on the outside of one arm of the U-shaped bracket 61 by bolts and nuts. The output shaft of the reciprocating motor 65 is fixedly connected to one end of the bidirectional lead screw 63 by bolts and nuts. In use, the reciprocating motor 65 drives the two sliders 64 to move towards or away from each other, which can drive the two L-shaped connecting rods 7 and the two polishing brushes 8 to move towards or away from each other. Thus, the distance between the two polishing brushes 8 can be adjusted according to the needs of pipes with different inner diameters, so that they can contact and squeeze to polish the inner wall of the pipe, and retract to avoid contact with the inner wall of the pipe when movement is required. The polishing motor 5 drives the bidirectional reciprocating assembly 6 and the two polishing brushes 8 to rotate, so that the inner wall of the pipe can be polished.

[0026] Furthermore, in this application, the electric telescopic pole 1 31, the walking motor 34, the electric telescopic pole 2 41, the polishing motor 5, the reciprocating motor 65, the reciprocating battery 66, the wireless control switch 67, the camera 9, the distance sensor 10, the lighting lamp 11, the wireless controller 12, and the battery 13 are respectively electrically connected. All of the above devices can use conventional devices commonly used in the prior art, and their connection and control operation principles are all existing mature technologies. Therefore, their principles will not be further described here.
