[0001] The utility model relates to the technical field of pipeline welding, in particular to a pipeline welding port cleaning device. Background Art

[0002] Due to the long-term placement of the pipeline, burrs and deformations will appear at the pipeline welding points, so the welding points need to be cleaned before pipeline welding.

[0003] In the prior art, there is a utility model patent with a publication (announcement) number of CN215880438U and a name of a pipeline welding port cleaning device, which includes a fixed shell, a fixed shell, and a cleaning mechanism fixed to the inner side wall of the fixed shell through a sliding groove. The cleaning mechanism consists of a fixed rod, a cleaning block and an adjusting ring. One end of the fixed rod is a limit block, and the other end is fixed to the cleaning block by a nut. A positioning ring is arranged on the fixed rod above the cleaning block, and a handle is arranged on the side of the cleaning block close to the pipeline opening. After the utility model is installed, it can be cleaned by rotating the handle. The operation is simple and efficient. While avoiding direct contact, the shape of the cleaning block can ensure that no secondary damage to the product will occur.

[0004] The equipment of this patent is convenient for cleaning the welding parts of the pipeline, and will not cause secondary damage to the product during the cleaning process; however, when cleaning the welding parts of the pipeline, the equipment of this patent requires the staff to slide the cleaning block to surround the outer wall of the pipeline to clean it. Its operation is not only more labor-intensive for the staff but also inconvenient to operate, which in turn brings certain inconvenience to the user. Utility Model Content

[0005] The utility model aims to provide a pipeline welding port cleaning device.

[0006] The technical problem solved by the utility model is that it is inconvenient for workers to clean the welding parts of pipelines with the existing equipment.

[0007] The utility model can be implemented by the following technical scheme: a pipeline welding port cleaning device comprises an annular plate for supporting the pipeline, the outer wall of the annular plate penetrates and is slidably connected with a sliding plate, an arc plate is fixedly installed on a side of the sliding plate away from the annular plate, and a first grinding sheet is pasted on a side of the arc plate close to the pipeline welding port, and the first grinding sheet and the arc plate are detachably designed, so that the user can selectively replace the first grinding sheet according to the actual use of the first grinding sheet;

[0008] The inner cavity of the annular plate is provided with a driving mechanism that enables the sliding plate to perform circular motion around the center of the annular plate. The driving mechanism includes a driven gear rotatably connected to the inner cavity of the annular plate and fixedly connected to the sliding plate. The inner cavity of the annular plate is rotatably connected to a driving gear meshing with the driven gear.

[0009] A further technical improvement of the utility model is that a rotating rod is rotatably connected to the outer wall of the annular plate, the rotating rod is fixedly connected to the driving gear, and the driving gear can be rotated synchronously by rotating the rotating rod.

[0010] A further technical improvement of the utility model is that the top and bottom ends of the first grinding sheet away from the arc plate are respectively slidably connected to a pipe inner contact plate and a pipe outer contact plate, and the shapes of the pipe inner contact plate and the pipe outer contact plate are both arc-shaped, thereby facilitating their contact with the inner and outer walls of the pipe, and thus facilitating subsequent cleaning.

[0011] A further technical improvement of the utility model is that a second polishing sheet and a third polishing sheet are respectively pasted on opposite sides of the pipe inner contact plate and the pipe outer contact plate. Through the detachable design of the second polishing sheet, the third polishing sheet and the pipe inner contact plate and the pipe outer contact plate, the user can selectively replace the second polishing sheet and the third polishing sheet according to their actual usage.

[0012] A further technical improvement of the utility model lies in that: the inner cavity of the arc plate is provided with an adjustment mechanism which enables the inner contact plate of the pipeline and the outer contact plate of the pipeline to move relative to or oppositely, the adjustment mechanism comprises a bidirectional screw which is rotatably connected to the inner cavity of the arc plate, and the threaded sleeves on the two sections of the outer threads of the bidirectional screw which have opposite rotation directions are provided with two screw sleeves which are slidably connected to the inner cavity of the arc plate, the two screw sleeves are respectively fixedly connected to the inner contact plate of the pipeline and the outer contact plate of the pipeline, and the bidirectional screw is rotated to enable the two screw sleeves on the outer threads of the bidirectional screw to move relative to or oppositely.

[0013] A further technical improvement of the utility model is that: the inner cavity of the annular plate is provided with a pipeline fixing mechanism, the pipeline fixing mechanism includes a second clamping plate fixedly connected to the inner cavity of the annular plate, the inner cavity of the annular plate is floatingly connected with a first clamping plate corresponding one to one to the second clamping plate, and anti-slip pads are fixedly installed on the opposite sides of the first clamping plate and the second clamping plate. The anti-slip pads are preferably rubber pads. The provision of the rubber pads facilitates the first clamping plate and the second clamping plate to stably support the pipeline to be cleaned, thereby facilitating the orderly progress of subsequent cleaning work.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model moves the annular plate so that the first grinding sheet on the annular plate can contact the welding part of the pipe, and then rotates the rotating rod to rotate the driving gear. When the driving gear rotates, it drives the driven gear to rotate through meshing action. The rotation of the driven gear facilitates the first grinding sheet on the annular plate to make a circular motion around the center of the annular plate. There is no need for the staff to manually clean the outer peripheral wall of the pipe, which is conducive to simplifying the overall operation steps of the equipment, reducing the overall operation difficulty of the equipment, and thus conveniently meeting the user's use needs.

[0016] 2. The top and bottom ends of the first grinding plate of the utility model are respectively slidably connected with the inner contact plate of the pipeline and the outer contact plate of the pipeline, and the second grinding plate and the third grinding plate are fixedly installed on the inner contact plate of the pipeline and the outer contact plate of the pipeline, so as to facilitate the grinding and cleaning of the outer peripheral wall of the pipeline near the pipeline welding place, thereby further improving the use effect of the equipment; at the same time, before cleaning it, the distance between the inner contact plate of the pipeline and the outer contact plate of the pipeline can be adjusted according to the actual thickness of the pipeline to be cleaned. During the adjustment, the handle is rotated to rotate the bidirectional screw. Since two sections of external threads with opposite thread rotation directions are arranged on one side of the bidirectional screw near the end, two thread sleeves are arranged on the thread sleeves of the two sections of external threads of the bidirectional screw. The rotation of the bidirectional screw drives the two thread sleeves on the external threads to move relative to or oppositely, and the movement of the two thread sleeves drives the inner contact plate of the pipeline and the outer contact plate of the pipeline to move synchronously, thereby facilitating the second grinding plate and the third grinding plate fixedly connected with the inner contact plate of the pipeline and the outer contact plate of the pipeline to be close to the inner and outer walls of the pipeline, thereby further improving the use effect of the equipment and facilitating use.

[0030] The inner cavity of the annular plate 2 is rotatably connected to a driven gear 3 located on one side of the threaded rod 21. The inner cavity of the annular plate 2 is rotatably connected to a driving gear 32 meshing with the driven gear 3. A rotating rod 31 is fixedly connected to the axis of the driving gear 32. One end of the rotating rod 31 passes through the annular plate 2 and extends to the outer wall of the annular plate 2. A rotating handle 33 is fixedly installed on one end of the rotating rod 31 extending to the outer wall of the annular plate 2. The other end of the rotating rod 31 is rotatably connected to the inner cavity of the annular plate 2 through a bearing. The outer wall of the annular plate 2 and away from the rotating handle 33 A sliding plate 34 fixedly connected to the outer wall of the driven gear 3 is slidably connected through one side of the sliding plate 34, an arc plate 35 is fixedly installed on the side of the sliding plate 34 away from the driven gear 3, a first grinding sheet 36 is pasted on the side of the arc plate 35 close to the pipe, and a pipe outer contact plate 38 and a pipe inner contact plate 37 are slidably connected to the top and bottom ends of the first grinding sheet 36 away from the arc plate 35, respectively, and a second grinding sheet 39 and a third grinding sheet 310 are pasted on the opposite sides of the pipe inner contact plate 37 and the pipe outer contact plate 38, respectively.

[0031] The inner cavity of the arc plate 35 is rotatably connected to a bidirectional screw 4, and one side of the bidirectional screw 4 near the end is provided with two sections of external threads with opposite thread rotation directions. The threaded sleeves on the two sections of external threads of the bidirectional screw 4 are provided with two screw sleeves 41 that are slidably connected to the inner cavity of the arc plate 35, and the two screw sleeves 41 are fixedly connected to the inner contact plate 37 of the pipeline and the outer contact plate 38 of the pipeline respectively.

[0032] One end of the bidirectional screw 4 passes through the arc plate 35 and extends to the top surface of the arc plate 35. A handle 42 is fixedly installed on the end of the bidirectional screw 4 extending to the top surface of the arc plate 35. The outer wall of the handle 42 is engraved with anti-slip grooves.

The movement of the two screw sleeves 41 drives the inner contact plate 37 of the pipeline and the outer contact plate 38 of the pipeline to move synchronously, thereby facilitating the second grinding sheet 39 and the third grinding sheet 310 respectively fixedly connected to the inner contact plate 37 of the pipeline and the outer contact plate 38 of the pipeline to be close to the inner and outer walls of the pipeline. After adjustment, the rotating rod 31 is rotated to rotate the driving gear 32. When the driving gear 32 rotates, the driven gear 3 is driven to rotate through meshing. The rotation of the driven gear 3 facilitates the good grinding of the welding part of the pipeline and facilitates its cleaning. After cleaning, the annular plate 2 can be separated from the pipeline.
