Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and more specifically to a pipe polishing device for building construction. Background Technology

[0002] Pipes are frequently used during construction and are usually stored in warehouses. Due to the complex environment of warehouses, the surface of pipes is prone to rust after being corroded. When used again, the surface of the pipes needs to be polished and then coated with appropriate protective paint.

[0003] Current pipe polishing equipment typically works by first clamping the pipe with a clamping mechanism, and then polishing the outer surface of the pipe with a polishing mechanism. However, the presence of the clamping mechanism can hinder the operation of the polishing mechanism, preventing the parts of the pipe that come into contact with the clamping mechanism from being polished. These parts often require manual polishing by workers afterward, which affects polishing efficiency. Summary of the Invention

[0031] like Figures 1-8As shown, the present invention provides a pipe polishing device for building construction, including a base 10 and a control cabinet, as well as an outer wall polishing mechanism 20 and two inner wall polishing mechanisms.

[0032] The outer wall polishing mechanism 20 is used to polish the outer wall of the pipe.

[0033] Two inner wall polishing mechanisms are respectively arranged on both sides of the outer wall polishing mechanism 20. The inner wall polishing mechanism includes a drive assembly 40, a support assembly 50 and an inner wall polishing assembly 60.

[0034] The drive assembly 40 includes a first guide rail 41, a first slider 42, a first lead screw 43, a first motor 44, a vertical plate 45, a first rotating shaft 46, a rotating plate 47, and a second motor 48. The first guide rail 41 is fixedly mounted laterally on the base 10. The first slider 42 is disposed on the first guide rail 41 and slidably connected to it. The first lead screw 43 passes laterally through the first slider 42, and both ends are rotatably connected to the base 10; the first lead screw 43 is threadedly connected to the first slider 42. The first motor 44 is fixedly mounted on the base 10 and electrically connected to the control cabinet; the first motor 44 controls the rotation of the first lead screw 43. The vertical plate 45 is fixedly mounted on the first slider 42. The first rotating shaft 46 is arranged laterally and rotatably connected to the vertical plate 45. The rotating plate 47 is arranged longitudinally, and its middle portion is fixedly mounted on the first rotating shaft 46. The second motor 48 is fixedly mounted on the vertical plate 45 and electrically connected to the control cabinet; the second motor 48 controls the rotation of the first rotating shaft 46.

[0035] The support assembly 50 is mounted on the rotating plate 47 and is used to provide support for the inner wall of the pipe.

[0036] The inner wall polishing assembly 60 is used to polish the inner wall of the pipe.

[0037] For ease of describing the working principle, the two inner wall polishing mechanisms will be named the first inner wall polishing mechanism 31 and the second inner wall polishing mechanism 32 in the following text.

[0038] In the initial state, the first inner wall polishing mechanism 31 and the second inner wall polishing mechanism 32 are located at the two ends of the base 10, and the support assembly 50 is located above the inner wall polishing assembly 60.

[0039] The specific working process of this device is as follows:

[0040] First, workers use hoisting equipment to lift the pipe between the first inner wall polishing mechanism 31 and the second inner wall polishing mechanism 32. Then, the control cabinet starts the first motor 44 of the first and second inner wall polishing mechanisms 31 and 32. The first motor 44 drives the first lead screw 43 to rotate. Under the action of the first guide rail 41, the first slider 42 moves the vertical plate 45 inward until the support assembly 50 enters the pipe. Then, the support assembly 50 starts to support the inner wall of the pipe. At this time, the support assembly 50 of the first and second inner wall polishing mechanisms 31 respectively supports the inner walls of the first and second ends of the pipe.

[0041] In the second step, the staff controls the second motor 48 of the first inner wall polishing mechanism 31 and the second motor 48 of the second inner wall polishing mechanism 32 to start synchronously through the control cabinet. The second motor 48 will drive the first rotating shaft 46 and the rotating plate 47 to rotate, and the pipe will move synchronously until the outer wall of the pipe contacts the outer wall polishing mechanism 20. At this time, the outer wall polishing mechanism 20 is used to polish the outer wall of the pipe.

[0042] In the third step, the first motor 44 of the first inner wall polishing mechanism 31 drives the first lead screw 43 to reverse until its support assembly 50 disengages from the pipe. Then, the control cabinet controls the second motor 48 of the first inner wall polishing mechanism 31 to start, and the second motor 48 drives the first rotating shaft 46 and the rotating plate 47 to rotate until its inner wall polishing assembly 60 is aligned with the pipe. Next, the control cabinet controls the first motor 44 of the first inner wall polishing mechanism 31 to drive the first lead screw 43 to rotate forward until its inner wall polishing assembly 60 enters the pipe. At this time, the inner wall polishing assembly 60 is used to polish the inner wall of the first end of the pipe.

[0043] In the fourth step, the control cabinet controls the first motor 44 of the first inner wall polishing mechanism 31 to drive the first lead screw 43 in reverse rotation until its inner wall polishing component 60 disengages from the pipe. Then, the control cabinet controls the second motor 48 of the first inner wall polishing mechanism 31 to start, and the second motor 48 drives the first rotating shaft 46 and the rotating plate 47 to rotate until its support component 50 is aligned with the pipe. Next, the control cabinet controls the first motor 44 of the first inner wall polishing mechanism 31 to drive the first lead screw 43 in forward rotation until its support polishing component enters the pipe, at which point the support component 50 provides support to the inner wall of the first end of the pipe.

[0044] In the fifth step, the first motor 44 of the second inner wall polishing mechanism 32 drives the first lead screw 43 to reverse until its support assembly 50 disengages from the pipe. Then, the control cabinet controls the second motor 48 of the second inner wall polishing mechanism 32 to start, and the second motor 48 drives the first rotating shaft 46 and the rotating plate 47 to rotate until its inner wall polishing assembly 60 is aligned with the pipe. Next, the control cabinet controls the first motor 44 of the first inner wall polishing mechanism 31 to drive the first lead screw 43 to rotate forward until its inner wall polishing assembly 60 enters the pipe. At this time, the inner wall polishing assembly 60 is used to polish the inner wall of the second end of the pipe.

[0045] The sixth step involves the staff suspending the pipe using hoisting equipment. The control cabinet then controls the first motor 44 of the first inner wall polishing mechanism 31 and the first motor 44 of the second inner wall polishing mechanism 32 to start synchronously, driving the corresponding first lead screw 43 to reverse until the support component 50 of the first inner wall polishing mechanism 31 and the inner wall polishing component 60 of the second inner wall polishing mechanism 32 are detached from the pipe. The pipe can then be transported away.

[0046] In operation, this device first supports the inner walls at both ends of the pipe through the support components 50 of the first inner wall polishing mechanism 31 and the second inner wall polishing mechanism 32, respectively. Then, the outer wall polishing mechanism 20 polishes the outer wall of the pipe. Subsequently, the two inner wall polishing mechanisms work together to polish both ends of the inner wall of the pipe sequentially. There is no obstruction during the polishing process, thus enabling automatic, all-around polishing of the pipe and improving polishing efficiency.

[0047] In one embodiment, the outer wall polishing mechanism 20 includes a second guide rail 21, a second slider 22, a second lead screw 23, a third motor 24, a fourth motor 25, and an outer wall polishing wheel 26.

[0048] The second guide rail 21 is fixedly mounted laterally on the base 10. The second slider 22 is disposed on the second guide rail 21 and slidably connected to the second guide rail 21. The second lead screw 23 passes laterally through the second slider 22, and both ends are rotatably connected to the base 10. The second lead screw 23 is threadedly connected to the second slider 22. The third motor 24 is fixedly mounted on the base 10 and electrically connected to the control cabinet. The third motor 24 is used to control the rotation of the second lead screw 23. The fourth motor 25 is fixedly mounted on the second slider 22 and electrically connected to the control cabinet. The outer wall polishing wheel 26 is fixedly mounted on the output shaft of the fourth motor 25.

[0049] When the outer wall polishing mechanism 20 is working, the control cabinet controls the fourth motor 25 to start, which drives the outer wall polishing wheel 26 to rotate, thereby polishing the outer wall of the pipe it contacts. Then, the control cabinet controls the third motor 24 to start, which drives the second lead screw 23 to rotate. Under the action of the second guide rail 21, the second slider 22 will drive the fourth motor 25 to move left and right, thereby polishing the outer wall of the pipe laterally. Next, the control cabinet controls the second motor 48 of the first inner wall polishing mechanism 31 and the second motor 48 of the second inner wall polishing mechanism 32 to start synchronously. Under the action of the corresponding support components 50, the pipe will rotate, thereby causing the outer wall polishing wheel 26 to fully polish the outer wall of the pipe.

[0050] In one embodiment, the support assembly 50 includes a second rotating shaft 51, a rotating disk 52, an adjusting disk 53, a gear ring 54, a fifth motor 55, a gear 56, and multiple guide shafts 57.

[0051] The second rotating shaft 51 is arranged laterally and rotatably connected to the first end of the rotating plate 47. A rotating disk 52 is fixedly mounted on the second rotating shaft 51, with its axis collinear with that of the second rotating shaft 51. The rotating disk 52 has multiple radially extending and laterally penetrating guide grooves 521, spaced circumferentially along its length. An adjusting disk 53 is rotatably connected to the rotating disk 52 via a third rotating shaft 58, with its axis collinear with that of the third rotating shaft 58. The adjusting disk 53 has multiple radially extending and laterally penetrating arc-shaped grooves 531, each corresponding to one of the guide grooves 521. A gear ring 54 is fixedly mounted on the adjusting disk 53. A fifth motor 55 is fixedly mounted on the rotating disk 52 and electrically connected to the control cabinet. A gear 56 is fixedly mounted on the output shaft of the fifth motor 55 and meshes with the gear ring 54. Multiple guide shafts 57 are correspondingly arranged with multiple guide grooves 521. The guide shafts 57 pass through the corresponding guide grooves 521 and arc-shaped grooves 531 laterally, and the guide shafts 57 slide in contact with the inner walls of the guide grooves 521 and the arc-shaped grooves 531. A support plate 59 is fixedly installed on the inner end face of the guide shaft 57, and a baffle 571 is fixedly installed on the outer end face of the guide shaft 57.

[0052] In the initial state, multiple guide shafts 57 are close to the axis of the rotating disk 52.

[0053] After the support assembly 50 enters the pipe, the control cabinet starts the fifth motor 55. The fifth motor 55 drives the gear 56 to rotate, and under the transmission of the gear ring 54, the rotating disk 52 will rotate. Under the action of the guide groove 521, the arc groove 531 of the rotating disk 52 will generate an outward pushing force on the guide shaft 57 during rotation, thereby causing multiple support plates 59 to move outward synchronously until they press against the inner wall of the pipe, forming support for the inner wall of the pipe. When the control cabinet controls the fifth motor 55 to drive the gear 56 to reverse, the multiple support plates 59 will move inward synchronously until they disengage from the inner wall of the pipe.

[0054] This support component 50 has a simple structure and is easy to manufacture and produce.

[0055] It is worth noting that this device also has the following advantages: 1. Due to the function of the drive component 40, the distance between the two support components 50 can be adjusted as needed, thus making it suitable for pipes of different lengths. 2. This device uses the second motor 48 to drive the first rotating shaft 46 and the rotating plate 47 to rotate, and the pipe moves synchronously until the outer wall of the pipe contacts the outer wall polishing mechanism 20. Then, the outer wall polishing mechanism 20 polishes the outer wall of the pipe. Therefore, the polishing of the outer wall of the pipe is not affected by its diameter and can be applied to pipes of different diameters.

[0056] In one embodiment, the support plate 59 has an arc-shaped structure with an inward-facing opening to adapt to the shape of the pipe and improve support stability.

[0057] In one embodiment, the inner wall polishing assembly 60 includes a third slider 61, a crossbar 62, an inner wall polishing wheel 63, and a sixth motor 64. The third slider 61 is disposed at the second end of the rotating plate 47 and connected to the rotating plate 47. The crossbar 62 is fixedly mounted on the third slider 61 laterally. The inner wall polishing wheel 63 is rotatably connected to the outer end of the crossbar 62. The sixth motor 64 is fixedly mounted on the crossbar 62 and electrically connected to the control cabinet; the sixth motor 64 is used to control the rotational connection of the inner wall polishing wheel 63.

[0058] In one embodiment, the inner wall polishing assembly 60 further includes a guide rod 65, a third lead screw 66, and a seventh motor 67. The guide rod 65 is fixedly connected to the rotating plate 47 and also slidably connected to the third slider 61. The third lead screw 66 passes through the third slider 61 and is rotatably connected to the rotating plate 47 at both ends; the third lead screw 66 is threadedly connected to the third slider 61. The seventh motor 67 is fixedly mounted on the rotating plate 47 and electrically connected to the control cabinet; the seventh motor 67 is used to control the rotation of the third slider 61.

[0059] When the inner wall polishing assembly 60 is working, the seventh motor 67 of the control cabinet starts, driving the third lead screw 66 to rotate. Under the action of the guide rod 65, the third slider 61 moves until the inner wall polishing wheel 63 contacts the inner wall of the pipe. Then the control cabinet controls the sixth motor 64 to start, which drives the inner wall polishing wheel 63 to rotate, thereby polishing the inner wall of the pipe.

[0060] This internal wall polishing component 60 has a simple structure, is easy to operate, and can be applied to pipes with different inner diameters, thus improving the practicality of the device.

[0061] In one embodiment, the drive assembly 40 further includes reinforcing ribs, which are fixedly connected to both the first slider 42 and the upright plate 45 to improve the strength of the upright plate 45.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
