[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.
[0021] The following describes the efficient bellows inner wall polishing device according to the embodiment of the utility model in conjunction with the accompanying drawings.
[0022] like Figure 1 and Figure 2 As shown, the highly efficient bellows inner wall polishing device provided by the embodiment of the utility model comprises a base 1, a driving mechanism 2 and a polishing mechanism 3.
[0023] The driving mechanism 2 is arranged on the outside of the base 1, and is used to drive the base 1 to move in the corrugated tube 4. The driving mechanism 2 includes a side support arm 23 and a driving wheel 21, wherein one end of the side support arm 23 is elastically hinged to the base 1, and the driving wheel 21 is arranged at the other end of the side support arm 23.
[0024] The polishing mechanism 3 is arranged at one end of the base 1, and the polishing mechanism 3 includes a polishing motor 36, a spring pull arm 34 and a brush seat 32, wherein the polishing motor 36 is arranged at the end of the base 1, the spring pull arm 34 is hinged to the power shaft of the polishing motor 36, and the brush seat 32 is arranged at one end of the spring pull arm 34 away from the polishing motor 36.
[0025] Specifically, the present application can smoothly deliver the device into the corrugated tube 4 through the driving mechanism 2, and the driving wheel 21 can fix and grasp the inner wall of the corrugated tube 4 through the elastically expandable side support arm 23, and the inner wall of the corrugated tube 4 is rotationally polished through the rotatable cleaning mechanism, and the polishing radius can be adjusted according to the inner diameter of the tube wall, which is suitable for cleaning the inner wall of the corrugated tube 4 with different diameters.
[0026] In one embodiment of the present invention, Figure 1 and Figure 2As shown, a tension spring 35 is sleeved on the outside of the spring arm 34, and a counterweight slider 33 is also slidably sleeved on the outside of the spring arm 34. One end of the tension spring 35 is connected to the counterweight slider 33, and the other end of the tension spring 35 is connected to the bottom of the spring arm 34.
[0027] A movable slot 37 is provided on the power shaft of the polishing motor 36 , and a spring pull arm 34 is hinged inside the movable slot 37 . A spring pull rod 38 is hinged inside the movable slot 37 , and the top end of the spring pull rod 38 is hinged to the spring pull arm 34 .
[0028] Specifically, when the polishing motor 36 stops, the spring arm 34 is reset and retracted, and the counterweight slider 33 slides to the bottom of the spring arm 34 under the action of the tension spring 35, and the spring pull rod 38 retracts, so that the spring arm 34 has a minimum rotation radius, which facilitates the polishing mechanism 3 to enter the inside of the bellows 4. As the polishing motor 36 is started, the counterweight slider 33 is increased in rotation radius due to the centrifugal force, driving the spring arm 34 to extend, and at the same time pushing the brush holder 32 to increase the rotation radius until the polishing brush 31 on the brush holder 32 contacts the inner wall of the bellows 4, and the counterweight slider 33 stops at the relative position on the spring arm 34. When the polishing brush 31 rotates, the counterweight slider 33 generates downward pressure on the polishing brush 31, so that the polishing brush 31 can more fully polish and clean the inner wall of the bellows 4.
[0029] In one embodiment of the present invention, Figure 1 As shown, a spring support rod 24 is hinged on the base 1, and the top end of the spring support rod 24 is hinged to the side support arm 23. A driving motor 22 is arranged on the top of the side support arm 23, and the power shaft of the driving motor 22 is connected to the driving wheel 21. The spring support rod 24 is used to support the side support arm 23 to open to the outside of the base 1, so that the driving wheel 21 can support the inner wall of the corrugated tube 4, and the driving motor 22 is used to drive the driving wheel 21 to rotate, thereby sending the entire device into the designated position in the corrugated tube 4.
[0030] In one embodiment of the present invention, Figure 2 As shown, the brush holder 32 is elastically hinged with the top of the spring pull arm 34, so that the polishing brush 31 is in elastic contact with the inner wall of the bellows 4 to reduce hard contact damage. A detachable polishing brush 31 is provided on the brush holder 32 to facilitate replacement of the polishing brush 31.
[0031] In order to clearly explain the above embodiments, refer to Figure 1-3 The specific working principle of the high-efficiency bellows inner wall polishing device of the utility model is as follows: before use, the base 1 is pushed into the bellows 4, the polishing mechanism 3 is facing the inside of the bellows 4, and the side support arm 23 is opened by the elastic force of the spring support rod 24, so that the driving wheel 21 can fix and grasp the inner wall of the bellows 4, and start the driving motor 22. The driving motor 22 drives the driving wheel 21 to rotate, driving the base 1 and the polishing mechanism 3 to continuously enter the inside of the bellows 4.
[0032] While the driving motor 22 is rotating, the polishing motor 36 is started. The rotation of the polishing motor 36 drives the counterweight slider 33 to rotate. The counterweight slider 33 is increased by the centrifugal force, driving the spring pull arm 34 to extend, and at the same time pushing the brush seat 32 to increase the rotation radius until the polishing brush 31 on the brush seat 32 contacts the inner wall of the bellows 4. The counterweight slider 33 stops at the relative position on the spring pull arm 34. When the polishing brush 31 rotates, the counterweight slider 33 generates downward pressure on the polishing brush 31, increasing the friction of the polishing brush 31, so that the polishing brush 31 can more fully polish and clean the inner wall of the bellows 4.
[0033] In summary, the efficient corrugated pipe inner wall polishing equipment of the utility model embodiment can smoothly deliver the device into the corrugated pipe through the driving mechanism, and the driving wheel can fix the inner wall of the corrugated pipe through the elastically expandable side support arm, and the inner wall of the corrugated pipe is rotationally polished by the rotatable cleaning mechanism, and the polishing radius can be adjusted according to the inner diameter of the pipe wall, which is suitable for cleaning the inner walls of corrugated pipes of different diameters.
[0034] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
