[0023] The driving wheel 12 and the driven wheel 11 are located above the top center place of workbench 1, the steel cable 5 passes through the gap between the two, and the upper and lower surfaces of the steel cable 5 are slidably connected with the bottom of the driven wheel 11 and the top of the driving wheel 12 respectively. The winding wheel 6 is arranged on the left side of the top of the workbench 1, and the steel cable 5 for cleaning is wound on the surface of the winding wheel 6. By rotating the winding wheel 6, the extension of the steel cable 5 can be controlled, so that the cleaning operation inside the ash conveying pipe 4 can be completed.

[0024] Further, the left and right sides of the bottom of the ash conveying pipe 4 are connected with support seats 3, the bottom of the two support seats 3 is slidingly connected with the top of the workbench 1, the workbench 1 is internally provided with a rectangular groove 101 below the ash conveying pipe 4, the top of the workbench 1 is provided with a transversely arranged guide groove 102 on the left and right sides of the right end, the two guide grooves 102 are arranged in parallel with the ash conveying pipe 4, the bottom of the two support seats 3 is fixedly connected with a fixed rod 301, and the bottom of the two fixed rods 301 extends to the inside of the rectangular groove 101 and is slidingly connected with the inner wall of the guide groove 102.

[0025] The left and right sides of the bottom of the ash conveying pipe 4 are connected with support seats 3, which provides necessary support for the ash conveying pipe 4, and the bottom of the support seat 3 is slidingly connected with the top of the workbench 1, so that the ash conveying pipe 4 can be adjusted in position as needed. The top of the workbench 1 is provided with a transversely arranged guide groove 102 on the left and right sides of the right end, and the guide groove 102 is arranged in parallel with the ash conveying pipe 4, so as to ensure that the support seat 3 can move smoothly along the axial direction of the ash conveying pipe 4.

[0026] The bottom of the two support seats 3 is fixedly connected with a fixed rod 301, and the bottom of the fixed rod 301 extends to the inside of the rectangular groove 101 and is slidingly connected with the inner wall of the guide groove 102. Such design allows the support seat 3 and the ash conveying pipe 4 above it to translate within a certain range, so as to adapt to ash conveying pipes 4 of different lengths and ensure their stability and positioning accuracy.

[0027] Further, the front and rear surfaces of the driven wheel 11 and the driving wheel 12 are rotatably connected with support plates 2, the front support plate 2 is fixedly connected with a first motor 10 below, the output shaft of the first motor 10 penetrates the front support plate 2 and extends to the inner wall of the driving wheel 12 and is fixedly connected therewith, the front and rear surfaces of the winding wheel 6 are rotatably connected with side plates 7, and the bottom of the support plate 2 is fixedly connected with the top center of the workbench 1, and the bottom of the two side plates 7 is fixedly connected with the workbench 1 between the left front and rear ends of the top.

[0028] The first motor 10 directly drives the driving wheel 12, so that the steel cable 5 can be effectively pulled in and out of the inside of the ash conveying pipe 4, realizing the cleaning of the inner wall of the pipeline. This way improves the working efficiency and response speed of the system and ensures the continuity and stability of the cleaning process.

[0029] The driven wheel 11 and the driving wheel 12 are firmly installed on the workbench 1 through the support plates 2, and the winding wheel 6 is also fixed on the workbench 1 through the side plates 7, which increases the stability and reliability of the entire device, which helps to reduce vibration and displacement, thereby improving the cleaning effect.

[0031] By rotating the bidirectional threaded rod 8, the threaded block 9 can be moved in the opposite direction synchronously. Since the threaded block 9 is connected with the fixed rod 301 at the bottom of the support seat 3, the distance between the two support seats 3 can be accurately adjusted to adapt to different lengths of the ash conveying pipe 4.

[0032] Further, a second motor 13 is fixedly connected to the right center of the outer wall of the workbench 1, the output shaft of the second motor 13 is fixedly connected with the right end of the bidirectional threaded rod 8, and a protective cover 130 is arranged outside the second motor 13, one side of the protective cover 130 is fixedly connected with the right side of the outer wall of the workbench 1.

[0033] By driving the bidirectional threaded rod 8 with the second motor 13, the position of the support seat 3 can be automatically adjusted, which not only improves the work efficiency but also reduces the need for manual operation, making the entire device more intelligent and easy to operate. The second motor 13 can provide more precise power transmission to ensure the accurate control of the rotation speed and direction of the bidirectional threaded rod 8, thereby achieving precise positioning of the threaded block 9 and the support seat 3 connected therewith.

[0034] The protective cover 130 effectively protects the second motor 13 from external environmental factors, prolongs the service life of the device, and reduces the risk of personal injury caused by contact with operating parts, improving the safety of operation.

[0035] Further, guide rods 14 are fixedly connected between the left and right sides of the inner wall of the rectangular groove 101, the threaded blocks 9 are slidably connected with the guide rods 14, and the fixed rods 301 are fixedly connected to the top of the two threaded blocks 9, and the support seats 3 are fixedly connected to the top of the fixed rods 301.

[0036] The introduction of the guide rods 14 and the sliding connection mechanism significantly improves the stability and accuracy of the movement of the threaded blocks 9, ensuring accurate position adjustment of the support seats 3 even when the second motor 13 drives the bidirectional threaded rod 8 to make rapid or fine adjustments. The design of the guide rods 14 reduces the friction that the threaded blocks 9 may encounter during movement, making the entire adjustment process smoother and prolonging the service life of the device.

[0037] Further, the inner walls of the two support seats 3 are arc-shaped structures that fit the surface of the bottom of the ash conveying pipe 4. The two support seats 3 are each provided with an air bag 15. A plurality of air suction pipes 16 are fixedly connected in a circumferential array on the arc-shaped surface of the two air bags 15. The plurality of air suction pipes 16 extend to one side of the inner wall of the support seat 3 away from the air bag 15 and are fixedly connected thereto.

[0038] Further, the front side of each of the two air bags 15 is fixedly connected with a first elastic expansion pipe 17 and a second elastic expansion pipe 19. The first elastic expansion pipe 17 and the second elastic expansion pipe 19 extend to the front side outside the support seat 3 away from the air bag 15 and are fixedly connected thereto. The end of the first elastic expansion pipe 17 away from the air bag 15 is fixedly connected with the air suction end of a negative pressure pump 18. The negative pressure pump 18 is fixedly connected between one side thereof and the front side of the workbench 1. The end of the second elastic expansion pipe 19 away from the air bag 15 is fixedly connected with one side of the first elastic expansion pipe 17.

[0039] When it is necessary to fix the ash conveying pipe 4, the negative pressure pump 18 is started. It is connected to the air bag 15 through the first elastic expansion pipe 17 to extract the air in the air bag 15. As the internal pressure of the air bag 15 decreases, the air bag 15 will shrink. The plurality of air suction pipes 16 on the air bag 15 are arranged in a circumferential array to ensure that the pressure applied by the air bag 15 to the ash conveying pipe 4 during the shrinking process is uniformly distributed. This helps to prevent the ash conveying pipe 4 from being damaged due to excessive local pressure and provides a stable clamping force.

[0040] Through the combination of the air bag 15 and the air suction pipe 16, the air in the air bag 15 can be extracted under the action of the negative pressure pump 18, so that the ash conveying pipe 4 tightly abuts against the arc-shaped inner surface of the support seat 3, providing a stronger fixing effect and avoiding movement or vibration of the ash conveying pipe 4 during cleaning.

[0041] Through the cooperation of the first elastic expansion pipe 17 and the second elastic expansion pipe 19, not only the stability of the position of the air bag 15 can be ensured, but also stress can be effectively dispersed to reduce the risk of component damage caused by mechanical vibration and improve the overall safety. The use of the negative pressure pump 18 realizes the automatic inflation and deflation process of the air bag 15, simplifies the operation process, improves the work efficiency, and reduces the need for manual intervention.

[0042] Further, the top of each of the two support seats 3 is provided with an L-shaped plate 20. The bottom of the L-shaped plate 20 is fixedly connected with the rear side surface of the support seat 3. A vertical electric push rod 21 penetrates through the top of each of the two L-shaped plates 20. The telescopic end of each of the two electric push rods 21 extends to the lower inside of the two L-shaped plates 20 and is slidably connected therewith. The bottom telescopic end of each of the two electric push rods 21 is fixedly connected with an arc-shaped cover plate 22. The inner wall top of each of the two arc-shaped cover plates 22 is fixedly connected with a rubber pad 23. The inner wall top of the rubber pad 23 abuts against the top surface of the ash conveying pipe 4.

[0043] The arc-shaped cover plate 22 is driven to move up and down by the electric push rod 21, which can make the rubber pad 23 tightly fit the top surface of the ash conveying pipe 4, providing additional fixing force to prevent the ash conveying pipe 4 from shifting or vibrating during cleaning. Since the electric push rod 21 can accurately adjust the position of the arc-shaped cover plate 22, and the rubber pad 23 has a certain elasticity, this design can adapt to ash conveying pipes 4 of different diameters, improving the versatility and practicality of the equipment.

[0044] The automatic clamping and loosening process is realized by the electric push rod 21, simplifying the operation process, improving the work efficiency, and reducing the need for manual intervention. The operator can easily adjust the working state of the electric push rod 21 through the control system to adapt to different working conditions. The rubber pad 23 not only provides good friction, but also effectively buffers the direct contact between the arc-shaped cover plate 22 and the ash conveying pipe 4, preventing damage to the surface of the ash conveying pipe 4 and prolonging the service life of the equipment.

[0045] First, place the ash conveying pipe 4 on the support seat 3, the inner wall of which is an arc-shaped structure that fits the bottom surface of the ash conveying pipe 4, ensuring preliminary positioning. The two support seats 3 have air bags 15 inside, and the arc-shaped surface of the air bags 15 is fixedly connected with a plurality of air extraction pipes 16 arranged in a circular array. Start the negative pressure pump 18 to extract air from the air bags 15 through the first elastic extension pipe 17. As the air bags 15 contract, the air extraction pipes 16 will tightly adhere to the outer surface of the ash conveying pipe 4, providing additional clamping force to prevent the ash conveying pipe 4 from moving or vibrating during cleaning.

[0046] The second motor 13 is used to drive the bidirectional threaded rod 8 to rotate, and the bidirectional threaded rod 8 is rotatably connected to the left and right sides of the inner wall of the rectangular groove 101 at both ends, and guided by the guide rod 14 to move the threaded blocks 9 on both sides synchronously inward or outward. The fixed rod 301 is fixedly connected to the top of the threaded block 9, and extends to the top of the workbench 1 and is fixedly connected with the support seat 3, so that the position of the support seat 3 can be accurately adjusted as the threaded block 9 moves, adapting to ash conveying pipes 4 of different lengths.

[0047] The arc-shaped cover plate 22 is driven to move up and down by the electric push rod 21, which can make the rubber pad 23 tightly fit the top surface of the ash conveying pipe 4, providing additional fixing force to prevent the ash conveying pipe 4 from shifting or vibrating during cleaning. Since the electric push rod 21 can accurately adjust the position of the arc-shaped cover plate 22, and the rubber pad 23 has a certain elasticity, this design can adapt to ash conveying pipes 4 of different diameters, improving the versatility and practicality of the equipment.

[0048] The first motor 10 drives the driving wheel 12 to rotate, and the steel cable 5 enters the inside of the ash conveying pipe 4 through the gap between the driving wheel 12 and the driven wheel 11, and the winding wheel 6 is rotatably connected with the side plates 7 on the front and back surfaces, and the bottom of the side plates 7 is fixedly connected with the left side of the top of the workbench 1, so that the stability of the winding wheel 6 is ensured. The steel cable 5 is pulled in and out of the inside of the ash conveying pipe 4 through the rotation of the driving wheel 12 driven by the first motor 10, and the cleaning operation on the inner wall of the pipe is completed.

[0049] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
