DETAILED DESCRIPTION
[0020] The embodiments of the utility model are described in detail below, examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as a limitation of the utility model.
[0021] The inner wall cleaning device for large-diameter expansion joint according to the embodiments of the utility model is described below in combination with the drawings.
[0022] As Figure 1 , Figure 2 shown, the inner wall cleaning device for large-diameter expansion joint provided by the embodiments of the utility model includes a tray 1, and a cleaning mechanism 2, a drive mechanism 3 and a clamping mechanism 4 arranged on the tray 1, wherein the drive mechanism 3 is used to drive the cleaning mechanism 2 to rotate, and the clamping mechanism 4 is used to clamp the expansion joint 5.
[0023] The drive mechanism 3 includes a drive motor 31 arranged on the tray 1, the cleaning mechanism 2 is arranged on the power shaft of the drive motor 31, and the cleaning mechanism 2 includes an elastic telescopic arm 24 and a cleaning roller assembly 23, wherein the elastic telescopic arm 24 is arranged on the power shaft of the drive motor 31, and the cleaning roller assembly 23 is arranged at the end of the elastic telescopic arm 24.
[0024] The clamping mechanism 4 includes a moving guide rail 44 and a clamp 41, wherein the moving guide rail 44 is arranged on the tray 1, and the clamp 41 is arranged on the output shaft of the moving guide rail 44, and the clamp 41 is used to support the outer wall of the expansion joint 5.
[0025] Specifically, the large-diameter expansion joint inner wall cleaning device first clamps the expansion joint 5 vertically through the clamping mechanism 4, and then rotates and cleans the inner wall of the expansion joint 5 through the cleaning roller assembly 23 in the cleaning mechanism 2 driven by the driving mechanism 3. In the rotating process of the cleaning roller assembly 23, the inner wall of the expansion joint 5 is cleaned by the cleaning roller assembly 23 driven by the driving mechanism 3. In addition, the elastic telescopic arm 24 can be driven to different lengths by different rotating centrifugal forces of the driving mechanism 3. The elastic telescopic arm 24 is stretched and contracted by the centrifugal force to change the rotating radius of the cleaning roller assembly 23, so that the cleaning roller 231 can adapt to the expansion joint 5 of different diameters. The inner wall of the expansion joint 5 is cleaned by the rotating cleaning roller 231.
[0026] In an embodiment of the utility model, as shown in Figure 2 The cleaning roller assembly 23 comprises a cleaning roller 231, a tension spring rope 232 and a cleaning brush head 233. The cleaning roller 231 is rotatably arranged at the end of the elastic telescopic arm 24. The bottom of the cleaning roller 231 is provided with a cleaning roller motor 234. The tension spring rope 232 is arranged at the rotating side of the cleaning roller 231. The cleaning brush head 233 is arranged at the end of the tension spring rope 232.
[0027] Specifically, the cleaning roller 231 is driven to rotate by the cleaning roller motor 234. In the rotating process of the cleaning roller 231, the cleaning brush head 233 on the cleaning roller 231 is subjected to a rotating centrifugal force, so that the cleaning radius is increased. The greater the rotating speed of the cleaning roller 231, the greater the rotating centrifugal force acting on the cleaning brush head 233. The tension spring rope 232 is also elongated. The cleaning brush head 233 is more fully in contact with the inner wall of the expansion joint 5, and the cleaning force is greater. Conversely, the lower the rotating speed of the cleaning roller 231, the lower the cleaning force of the cleaning brush head 233 on the inner wall of the expansion joint 5. Therefore, the rotating speed of the cleaning roller 231 can be adjusted according to the cleaning degree.
[0028] In an embodiment of the utility model, as shown in Figures 1-4 The end of the elastic telescopic arm 24 is provided with a length-adjustable support roller support 22. The inner wall support roller 21 is arranged on the support roller support 22. The inner wall support roller 21 is used to support the inner wall of the expansion joint 5. The inner wall support roller 21 is parallel to the cleaning roller 231.
[0029] Specifically, in the rotating process of the cleaning roller 231 around the inner wall of the expansion joint 5, the inner wall support roller 21 cooperates with the length-adjustable support roller support 22 to determine the final rotating radius of the cleaning roller 231, so that a safety gap is left between the cleaning roller 231 and the inner wall of the expansion joint 5, preventing the cleaning roller 231 from being excessively pressed against the inner wall of the expansion joint 5 and causing damage to the inner wall of the expansion joint 5.
[0030] In an embodiment of the utility model, as shown in Figure 1As shown, the clamp 41 is L-shaped structure, the bottom of the clamp 41 is provided with a clamp bottom support 43, the clamp bottom support 43 is used for supporting the bottom of the expansion joint 5, the inner wall of the clamp 41 is provided with a non-slip pad 42, the clamp 41 is driven by the moving guide rail 44, so that the clamp 41 can clamp the outer wall of the expansion joint 5 of different diameters, and the non-slip pad 42 further clamps the expansion joint 5, so that the expansion joint 5 and the clamp 41 are prevented from sliding.
[0031] In an embodiment of the utility model, as shown in Figure 1 The clamp 41 is located below the elastic telescopic arm 24, the cleaning roller 231 and the inner wall supporting roller 21 are prevented from contacting the clamp 41, the cleaning roller 231 and the inner wall supporting roller 21 rotate safely, the elastic telescopic arm 24 is provided with a tension spring, in the case that the elastic telescopic arm 24 does not rotate, the elastic telescopic arm 24 is in the state of contraction, the expansion joint 5 is conveniently installed on the clamp 41, in the case that the elastic telescopic arm 24 rotates, the elastic telescopic arm 24 is elongated under the centrifugal force, and the cleaning roller 231 is contacted with the inner wall of the expansion joint 5 to clean.
[0032] In an embodiment of the utility model, as shown in Figure 1 The driving motor 31 is located at the middle position of the tray 1, and the driving motor 31 is further provided with a counterweight 32 on the power shaft, so that the rotating speed of the cleaning roller 231 is more stable.
[0033] In order to clearly illustrate the above embodiment, referring to Figures 1-4 The working principle of the large-diameter expansion joint inner wall cleaning device is as follows: in use, first, the moving guide rail 44 is adjusted to the appropriate position, and the expansion joint 5 is vertically placed on the clamp bottom support 43. Then, the moving guide rail 44 pushes the clamp 41 to clamp the outer wall of the expansion joint 5. Then, the elastic telescopic arm 24 in the cleaning mechanism 2 is rotated by the driving motor 31, and the elastic telescopic arm 24 is telescoped to different lengths due to different rotating centrifugal forces of the driving motor 31. When the elastic telescopic arm 24 is telescoped under the centrifugal force, the rotating radius of the cleaning roller assembly 23 changes, the rotating position of the cleaning roller 231 gradually approaches the inner wall of the expansion joint 5, so that the cleaning roller 231 can adapt to the cleaning work of the expansion joint 5 of different diameters.
[0034] During the rotation of the cleaning roller 231 around the inner wall of the expansion joint 5, the inner wall supporting roller 21 cooperates with the supporting roller support 22 of adjustable length to stabilize the final rotating radius of the cleaning roller 231, so that a safe gap is maintained between the cleaning roller 231 and the inner wall of the expansion joint 5, and the cleaning roller 231 is prevented from excessively pressing the inner wall of the expansion joint 5 to cause damage.
[0035] When the cleaning roller 231 rotates, the cleaning brush head 233 on the cleaning roller 231 is affected by the rotational centrifugal force, and the cleaning radius increases. Moreover, the higher the rotating speed of the cleaning roller 231, the greater the rotational centrifugal force on the cleaning brush head 233, the longer the tension spring rope 232 is pulled, the more sufficient the contact between the cleaning brush head 233 and the inner wall of the expansion joint 5, and the greater the cleaning force; on the contrary, the lower the rotating speed of the cleaning roller 231, the lower the cleaning force of the cleaning brush head 233 on the inner wall of the expansion joint 5. Therefore, the rotating speed of the cleaning roller 231 can be adjusted according to the cleaning requirement.
[0036] In conclusion, the large-diameter expansion joint inner wall cleaning device can vertically clamp the expansion joint through the clamping mechanism, and then rotate and clean the inner wall of the expansion joint through the cleaning roller assembly in the cleaning mechanism driven by the driving mechanism. During the rotating process of the cleaning roller assembly, the driving mechanism drives the cleaning roller assembly to clean the inner wall of the expansion joint. Different rotational centrifugal forces of the driving mechanism drive the elastic expansion arms to expand to different lengths. The expansion of the elastic expansion arms under the centrifugal force changes the rotating radius of the cleaning roller assembly, so that the cleaning roller can adapt to contact expansion joints with different diameters.
