Description

Technical Field

[0001] This utility model relates to the field of equipment and pipeline maintenance technology, specifically to a robot for equipment and pipeline maintenance. Background Technology

[0002] In industrial production and municipal pipeline networks, equipment and pipelines are prone to malfunctions due to corrosion, scaling, and blockage by foreign objects during long-term operation, requiring timely maintenance. Traditional maintenance methods rely on manual entry into or disassembly of pipelines, which suffers from problems such as limited working space, high safety risks, and low efficiency, and is difficult to conduct comprehensive inspections of long-distance, high-risk pipelines. Existing pipeline maintenance equipment often lacks flexibility, has limited maintenance functions, and cannot adapt to different pipe diameters, making it difficult to meet the precise maintenance needs under complex operating conditions. Therefore, there is an urgent need for a highly efficient, safe, and adaptable robot for equipment and pipeline maintenance.

[0003] Based on the above, the applicant believes the following deficiencies exist:

[0004] Existing pipe cleaning equipment lacks adjustable cleaning components, cannot adaptively adjust the brush head's fit according to the pipe's inner diameter, and can only be adapted to pipes of specific specifications. It has poor versatility for pipes with different inner diameters, resulting in blind spots in the cleaning range. Furthermore, it lacks a pre-treatment mechanism for softening dirt, and relies solely on dry brushing, leading to high frictional resistance, incomplete dirt removal, and low cleaning efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a robot for equipment and pipeline maintenance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a robot for equipment and pipeline maintenance, comprising a robot body, an adjustable wheel assembly mechanism on the surface of the robot body, and a ring-shaped cleaning mechanism on the surface of the robot body;

[0007] The annular cleaning mechanism includes a motor mounting slot located at the center of the front of the robot body. A control motor is installed inside the motor mounting slot. A rotating shaft is located on the front of the control motor. A connecting block is installed on the front of the rotating shaft. A second electrically controlled telescopic column is installed on the surface of the connecting block. An external connecting block is installed at the outer end of the second electrically controlled telescopic column. A cleaning brush is installed on the outer surface of the external connecting block. Liquid storage tanks are installed on both sides of the inner end of the external connecting block. A liquid pump is installed on the inner surface of the liquid storage tank. An infusion pipe is installed on the surface of the liquid pump. A nozzle is installed at the outer end of the infusion pipe. The connecting block surface of the annular cleaning mechanism has four sets of second electrically controlled telescopic columns arranged in a ring, and the outer ends of the second electrically controlled telescopic columns are connected to the external connecting blocks on which the cleaning brushes are installed. By adjusting the extension length of the second electrically controlled telescopic column, the cleaning brush can precisely conform to the inner wall of pipes with different inner diameters. In conjunction with the control motor driving the rotating shaft, the entire cleaning assembly rotates, achieving thorough cleaning of the pipe inner wall without dead angles. This avoids the problems of poor adaptability and blind spots in traditional cleaning equipment. Before wiping, the nozzle wets and softens the dirt on the inner wall of the pipe, reducing the frictional resistance between the cleaning brush and the pipe wall, while improving the dirt removal effect. Compared with dry brush cleaning alone, it is more efficient and more thorough. At the same time, the detection camera and light source work together to capture real-time images of the cleaning of the inner wall of the pipe, avoiding over-cleaning or insufficient cleaning, and improving the accuracy of maintenance operations.

[0008] Preferably, a telescopic column spindle protective sleeve is installed on the surface of the connecting block, the second electrically controlled telescopic column is disposed inside the telescopic column spindle protective sleeve, and four sets of the second electrically controlled telescopic column and the telescopic column spindle protective sleeve are provided and distributed in a ring on the four surfaces of the connecting block.

[0009] Preferably, a detection camera is installed at the center of the front of the external connecting block, light sources are installed on both sides of the front of the external connecting block, and the nozzle is installed at the end of the infusion tube away from the storage tank.

[0010] Preferably, the surface of the external connecting block has holes that match the nozzle, and the nozzle is disposed inside the holes.

[0011] Preferably, the adjustable wheel assembly includes a wheel seat mounted on the side of the robot body. A first electrically controlled telescopic column is installed at the center of the inner end of the wheel seat. A storage groove is formed on the outer surface of the wheel seat, and a wheel frame is installed inside the storage groove. A set of movable wheels is installed inside the wheel frame. Four sets of adjustable wheel assemblies are circumferentially mounted on the side of the robot body. The first electrically controlled telescopic column at the inner end of the wheel seat can drive the wheel frame to extend and retract along the storage groove, thereby adjusting the distance between the movable wheels and the robot body. By synchronously adjusting the extension and retraction of the four sets of first electrically controlled telescopic columns, the movable wheels can fit tightly against the inner walls of pipes with different inner diameters. The four circumferentially distributed movable wheels form a stable support, preventing the robot from tilting or swaying when walking inside the pipe, ensuring smooth movement. Simultaneously, the entire assembly is retractable, provides stable walking power, and is adaptable to complex pipe environments.

[0012] Preferably, the outer end of the first electrically controlled telescopic column is installed at the center of the inner surface of the wheel assembly frame, and the adjustable wheel assembly mechanism is provided in four sets, which are installed in a ring on the four sides of the robot body.

[0013] Compared with the prior art, this utility model provides a robot for equipment and pipeline maintenance, which has the following advantages:

[0014] 1. This pipeline maintenance robot is equipped with a ring-shaped cleaning mechanism. The connecting block of this mechanism has four sets of second electrically controlled telescopic columns arranged in a ring on its surface. The outer ends of these second electrically controlled telescopic columns are connected to external connecting blocks on which cleaning brushes are installed. By adjusting the extension length of the second electrically controlled telescopic columns, the cleaning brush can precisely conform to the inner walls of pipes with different inner diameters. Combined with a control motor driving the rotating shaft, the entire cleaning assembly rotates, achieving thorough cleaning of the pipe's inner walls without blind spots. This avoids the problems of poor adaptability and blind spots found in traditional cleaning equipment. Before wiping, the nozzle wets and softens the dirt on the pipe's inner wall, reducing friction between the cleaning brush and the pipe wall and improving the dirt removal effect. Compared to dry brush cleaning alone, this is more efficient and thorough. Simultaneously, the detection camera and light source work together to capture real-time images of the pipe's inner wall cleaning process, preventing over-cleaning or insufficient cleaning and improving the accuracy of maintenance operations.

[0015] 2. This pipeline maintenance robot is equipped with an adjustable wheel mechanism. Four sets of adjustable wheels are circularly mounted on the side of the robot's main body. The first electrically controlled telescopic column at the inner end of the wheel seat drives the wheel frame to extend and retract along the storage groove, thereby adjusting the distance between the moving wheels and the robot's main body. By synchronously adjusting the extension and retraction of the four sets of first electrically controlled telescopic columns, the moving wheels can be made to closely fit the inner walls of pipes with different inner diameters. The four circularly distributed moving wheels form a stable support, preventing the robot from tilting or swaying when moving inside the pipe, ensuring smooth movement. Furthermore, the robot is retractable, has stable walking power, and is adaptable to complex pipeline environments. Attached Figure Description

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-4 A robot for equipment pipeline maintenance includes a robot body 1, an adjustable wheel assembly 2 on the surface of the robot body 1, and a ring cleaning mechanism 3 on the surface of the robot body 1.

[0027] The annular cleaning mechanism 3 includes a motor mounting slot 31, which is located at the center of the front of the robot body 1. A control motor 32 is installed inside the motor mounting slot 31. A rotating shaft 33 is provided on the front of the control motor 32. A connecting block 34 is installed on the front of the rotating shaft 33. A second electrically controlled telescopic column 35 is installed on the surface of the connecting block 34. An external connecting block 37 is installed at the outer end of the second electrically controlled telescopic column 35. A cleaning brush 38 is installed on the outer surface of the external connecting block 37. Liquid storage tanks 39 are installed on both sides of the inner end of the external connecting block 37. A liquid pump 301 is installed on the inner surface of the liquid storage tank 39. An infusion pipe 302 is installed on the surface of the liquid pump 301. A nozzle 303 is installed at the outer end of the infusion pipe 302. The connecting block 34 of the annular cleaning mechanism 3 has four sets of second electrically controlled telescopic columns 35 arranged in a ring on its surface, and the outer ends of the second electrically controlled telescopic columns 35 are connected to the external connecting blocks 37 on which the cleaning brushes 38 are installed. By adjusting the extension length of the second electrically controlled telescopic column 35, the cleaning brush 38 can be driven to precisely fit the inner wall of pipes with different inner diameters. In conjunction with the control motor 32 driving the rotating shaft 33 to rotate the entire cleaning assembly, the inner wall of the pipe can be cleaned without dead angles, avoiding the problems of poor adaptability and cleaning blind spots of traditional cleaning equipment. Before wiping, the nozzle 303 wets and softens the dirt on the inner wall of the pipe, reducing the frictional resistance between the cleaning brush 38 and the pipe wall, and improving the dirt removal effect. Compared with dry brush cleaning alone, it is more efficient and cleaner. At the same time, the detection camera 304 and the light source 305 work together to capture the cleaning image of the inner wall of the pipe in real time, avoiding over-cleaning or under-cleaning, and improving the accuracy of maintenance operations.

[0028] A telescopic column spindle protective sleeve 36 is installed on the surface of the connecting block 34. The second electrically controlled telescopic column 35 is located inside the telescopic column spindle protective sleeve 36. There are four sets of the second electrically controlled telescopic column 35 and the telescopic column spindle protective sleeve 36, which are distributed in a ring on the four surfaces of the connecting block 34.

[0029] A detection camera 304 is installed at the center of the front of the external connection block 37, and light sources 305 are installed on both sides of the front of the external connection block 37. The nozzle 303 is installed at the end of the infusion tube 302 away from the liquid storage tank 39.

[0030] The surface of the external connecting block 37 has holes that match the nozzle 303, and the nozzle 303 is located inside the holes.

[0031] Example 2

[0032] Please see Figure 1-4 Based on Embodiment 1, the adjustable wheel mechanism 2 further includes a wheel seat 21, which is mounted on the side of the robot body 1. A first electrically controlled telescopic column 23 is installed at the center of the inner end of the wheel seat 21, and a storage groove 22 is opened on the outer surface of the wheel seat 21. A wheel frame 24 is set inside the storage groove 22, and a movable wheel set 25 is installed inside the wheel frame 24. Four sets of adjustable wheel mechanisms 2 are installed in a ring on the side of the robot body 1. The first electrically controlled telescopic column 23 at the inner end of the wheel seat 21 can drive the wheel frame 24 to extend and retract along the storage groove 22, thereby adjusting the distance between the movable wheel set 25 and the robot body 1. By synchronously adjusting the extension and retraction of the four sets of first electrically controlled telescopic columns 23, the movable wheel set 25 can be made to fit tightly against the inner wall of pipes with different inner diameters. The four sets of ring-distributed movable wheel sets 25 form a stable support, preventing the robot from tilting or swaying when walking in the pipe, ensuring the smoothness of the movement process. At the same time, the whole can be stored, the walking power is stable, and it is suitable for complex pipe environments.

[0033] The outer end of the first electrically controlled telescopic column 23 is installed at the center of the inner surface of the wheel frame 24. The adjustable wheel mechanism 2 is provided with four sets, which are installed in a ring on the four sides of the robot body 1.

[0034] In actual operation, when this device is used, the entire device is placed inside the pipe that needs to be cleaned. This device is suitable for cleaning straight pipes. The device is adjusted according to the inner diameter of the pipe. The first electrically controlled telescopic column (23) can drive the wheel frame (24) to extend and retract along the storage groove (22), thereby adjusting the distance between the moving wheel set (25) and the robot body (1). By synchronously adjusting the extension and retraction of the four sets of first electronically controlled telescopic columns (23), the moving wheel set (25) can be made to fit tightly against the inner wall of pipes with different inner diameters. The four sets of ring-shaped moving wheel sets (25) form a stable support, preventing the robot from tilting or shaking when walking in the pipe, and ensuring the smoothness of the movement process. The moving wheel set (25) inside the wheel set frame (24) provides stable walking power. With the support force of the first electronically controlled telescopic column (23), the robot can move forward and backward smoothly in the pipe. Even when facing the slight unevenness of the inner wall of the pipe, the moving wheel set (25) can be kept in effective contact with the pipe wall by extension and retraction adjustment, ensuring the reliability of the robot's movement during maintenance operations.

[0035] The positions of the external connecting block 37 and the cleaning brush 38 are adjusted by the second electrically controlled telescopic column 35. By adjusting the telescopic length of the second electrically controlled telescopic column (35), the cleaning brush (38) can be driven to precisely fit the inner wall of pipes with different inner diameters. With the control motor (32) driving the rotating shaft (33), the entire cleaning assembly is rotated, achieving a thorough cleaning of the inner wall of the pipe without dead angles. This avoids the problems of poor adaptability and blind spots in traditional cleaning equipment. The liquid storage tanks (39) on both sides of the inner end of the external connecting block (37) can store cleaning liquid. The liquid pump (301) delivers the cleaning liquid to the nozzle (303) through the delivery pipe (302) and sprays it out through the matching holes on the surface of the external connecting block (37). Before the cleaning brush (38) wipes, the dirt on the inner wall of the pipe is moistened and softened, reducing the frictional resistance between the cleaning brush (38) and the pipe wall, and improving the cleaning efficiency. Compared to dry brush cleaning alone, the dirt removal effect is more efficient and the cleaning is more thorough. The detection camera (304) in the center of the front of the external connecting block (37) can capture the cleaning image of the inner wall of the pipe in real time. The light sources (305) on both sides provide sufficient light for detection and cleaning. The operator can observe the cleaning progress and effect through the external terminal, and adjust the extension range of the second electric control telescopic column (35), control the speed of the motor (32) and the amount of cleaning liquid sprayed in a timely manner to avoid over-cleaning or substandard cleaning, and improve the accuracy of maintenance operations. At the same time, the second electric control telescopic column (35) is set inside the telescopic column main shaft protective sleeve (36), which can effectively prevent dirt and cleaning liquid from directly contacting the telescopic column main shaft during the cleaning process, reduce wear and corrosion, extend the service life of the second electric control telescopic column (35), and ensure the long-term stable operation of the mechanism.
