Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline application technology for offshore drilling platforms, and in particular to a rust removal device for pipe clamps on offshore oil drilling platforms. Background Technology
[0002] According to the patent document with publication number CN221248258U, the housing is fixed to the wall near the checkpoint by fixing bolts. Then, the drive motor drives the crank to rotate the rod and make the swing arm swing back and forth. The swing arm will cause the rotating shaft to rotate. At the same time, the swing arm will drive the prototype arm to slide back and forth along its axis. The telescopic spring will cause the telescopic connecting rod to drive the rust removal plate and sandpaper layer to rub and remove rust on the surface of the pipe clamp.
[0003] In this patent document, when removing rust from pipe clamps, the limited space of the swing chamber of the entire housing restricts the swing range of the swing arm. Consequently, the swing arm can only move the rust removal arm back and forth with a relatively small amplitude. When the rust removal arm moves back and forth, a telescopic spring is installed between the rust removal arm and the telescopic connecting rod. At this time, the rust removal arm's reciprocating movement is partially absorbed by the deformation of the telescopic spring. Furthermore, the telescopic spring also reduces the effective distance transmitted by the rust removal arm during its reciprocating movement during deformation. As a result, the distance the rust removal plate moves back and forth is less than the distance the rust removal arm moves. Moreover, when the rust removal plate encounters greater resistance, the extension amplitude of the telescopic spring increases, further reducing the overall rust removal speed and effectiveness.

[0032] The present invention will be further described below with reference to the accompanying drawings:
[0033] like Figures 1-10 As shown, a rust removal device for pipe clamps on an offshore oil drilling platform includes a protective mechanism 1. The protective mechanism 1 is equipped with a rust removal mechanism 2 and a flipping mechanism 3. The rust removal mechanism 2 and the flipping mechanism 3 form a closed ring structure.
[0034] In this embodiment: the protective mechanism 1 includes a protective cover 11, an arc-shaped cover 12 is hinged to the front side of the protective cover 11, a handle 13 is fixed to the rear side of the protective cover 11, the upper end of the arc-shaped cover 12 is provided with a latch for fixing to the upper end of the protective cover 11, and a driving structure 4 is provided at the rear side of the protective cover 11. By opening the latch, the arc-shaped cover 12 is flipped downward, thereby opening the front side of the protective cover 11. At the same time, the flipping of the arc-shaped cover 12 drives the flipping mechanism 3 to flip downward synchronously, thereby facilitating the insertion of the pipe clamp into the inner position of the rust removal mechanism 2.
[0035] In this embodiment: the rust removal mechanism 2 includes a main ring seat 21, a main gear ring 22 is fixed on one side of the main ring seat 21, a main support ring 24 is provided on the other side of the main ring seat 21, a plurality of main limiting plates 23 are fixed between the main ring seat 21 and the main support ring 24, a main grinding ring 25 is slidably connected on the plurality of main limiting plates 23, and a plurality of first springs 26 are fixed on the other side of the main grinding ring 25. The main gear ring 22 drives the main ring seat 21, the plurality of main limiting plates 23 and the main support ring 24 to rotate inside the protective cover 11 and the arc-shaped cover 12. At the same time, the plurality of main limiting plates 23 between the main ring seat 21 and the main support ring 24 drive the main grinding ring 25 to rotate inside the protective mechanism 1.
[0036] In this embodiment: the flipping mechanism 3 includes a secondary ring seat 31, a secondary gear ring 32 is fixed on one side of the secondary ring seat 31, a secondary support ring 34 is provided on the other side of the secondary ring seat 31, a plurality of secondary limiting plates 33 are fixed between the secondary support ring 34 and the secondary ring seat 31, a secondary grinding ring 35 is slidably connected on the plurality of secondary limiting plates 33, and a plurality of second springs 36 are fixed on the other side of the secondary grinding ring 35. The rotation of the main ring seat 21 is used to push the secondary ring seat 31 to rotate synchronously. At the same time, the secondary limiting plates 33 and the secondary support ring 34 will rotate synchronously, and the secondary limiting plates 33 will drive the secondary grinding ring 35 to also rotate synchronously with the secondary ring seat 31.
[0037] In this embodiment: multiple grinding steel wires are fixed to the inner rings of both the secondary grinding ring 35 and the main grinding ring 25. The other end of the first spring 26 is fixed to one side of the main support ring 24, and the other end of the second spring 36 is fixed to one side of the secondary support ring 34. The secondary grinding ring 35 has a second groove on its side for sliding on the secondary limiting plate 33, and the main grinding ring 25 has a first groove on its side for sliding on the main limiting plate 23. The inner sides of the protective cover 11 and the arc-shaped cover 12 are both arc-shaped strips. The outer sides of the main ring seat 21 and the secondary ring seat 31 are both provided with limiting grooves that fit onto the arc-shaped strips. The secondary grinding ring 35... The main grinding ring 25 and the secondary grinding ring 35 drive the inner rings of the grinding wires to rotate synchronously, thereby rotating and grinding the pipe clamp located inside the protective cover 11. Under the action of the drive structure 4, the main grinding ring 25 and the secondary grinding ring 35 slide on the main limit plate 23 and the secondary limit plate 33 respectively. At the same time, the first spring 26 and the second spring 36 begin to be compressed. When the drive structure 4 rotates past the toggle position, the first spring 26 and the second spring 36 drive the main grinding ring 25 and the secondary grinding ring 35 to reset to one side. Then, while the secondary grinding ring 35 and the main grinding ring 25 are rotating, they reciprocate to both sides.
[0038] In this embodiment: the drive structure 4 includes a shift fork 41, a boss 42 is fixed on one side of the rear end of the shift fork 41, a shift wheel 43 is provided on one side of the boss 42, a bevel gear 44 is provided on the front side of the shift wheel 43 for meshing with the auxiliary gear ring 32 and the main gear ring 22, a drive motor 45 is fixedly provided on the rear side of the protective cover 11, the shift wheel 43 and the bevel gear 44 are connected by a rotating shaft, and the rear end of the rotating shaft is fixedly connected to the rotating part of the drive motor 45. The shift fork 41 has a C-shaped structure, and the front end of the shift fork 41 is located between the main ring seat 21 and the main grinding ring 25. The drive motor 45 drives the rotating shaft to rotate synchronously, which in turn drives the actuating wheel 43 and the bevel gear 44 to rotate. The rotation of the bevel gear 44 meshes with the main gear ring 22 and the secondary gear ring 32, which in turn drives the main ring seat 21 and the secondary ring seat 31 to rotate. In addition, when the bevel gear 44 rotates, the actuating wheel 43 also rotates synchronously and alternately pushes the boss 42. The boss 42 drives the shift fork 41 to move synchronously, and the shift fork 41 pushes the main grinding ring 25 or the secondary grinding ring 35.
[0039] Working principle: When in use, first hold the handle 13 and place the protective mechanism 1 at the pipe clamp that needs to be polished. Then, open the latch to allow the arc-shaped cover 12 to flip downward, thereby opening the front side of the protective cover 11. At the same time, the flipping of the arc-shaped cover 12 drives the flipping mechanism 3 to flip downward synchronously. Then, the pipe clamp is placed into the inner ring position of the main ring seat 21. Then, the arc-shaped cover 12 is flipped and the flipping mechanism 3 on its inner side and the rust removal mechanism 2 in the protective mechanism 1 form a closed ring structure. At the same time, the latch is used to lock the arc-shaped cover 12 and the protective cover 11.
[0040] Subsequently, the rotating part of the drive motor 45 drives the rotating shaft to rotate, which in turn drives the actuating wheel 43 and the bevel gear 44 to rotate synchronously. When the bevel gear 44 rotates, it meshes with the main gear ring 22 to drive the main ring seat 21 to rotate within the protective cover 11 and the arc-shaped cover 12. At the same time, the rotation of the main ring seat 21 drives the auxiliary ring seat 31 to rotate synchronously within the protective cover 11 and the arc-shaped cover 12. When the main gear ring 22 drives the main ring seat 21, multiple main limiting plates 23, and the main support ring 24 to rotate inside the protective cover 11 and the arc-shaped cover 12, the multiple main limiting plates 23 drive the main grinding ring 25 to rotate along the arc-shaped strip inside the protective cover 11 and the arc-shaped cover 12. The grinding wires on the inner side of the grinding ring 25 are used to rotate and grind the pipe clamp. At the same time, when the main ring seat 21 pushes the auxiliary ring seat 31 to rotate, the auxiliary limiting plate 33 and the auxiliary support ring 34 on the other side of the auxiliary ring seat 31 will rotate synchronously. The auxiliary limiting plate 33 will drive the auxiliary grinding ring 35 to rotate synchronously with the auxiliary ring seat 31. At this time, the grinding wires on the inner side of the auxiliary grinding ring 35 will also grind the pipe clamp. When the auxiliary gear ring 32 rotates to the rear side of the protective cover 11 and meshes with the bevel gear 44, the auxiliary ring seat 31 pushes the main ring seat 21, so that the main ring seat 21 and the auxiliary ring seat 31 drive the entire rust removal mechanism 2 and the flipping mechanism 3 to rotate and grind inside the protective cover 11 and the arc-shaped cover 12.
[0041] Furthermore, when the bevel gear 44 rotates, the actuating wheel 43 also rotates synchronously and alternately pushes against the boss 42. When the actuating wheel 43 pushes against the boss 42, the entire boss 42 will move away from the actuating wheel 43. At the same time, the actuating wheel 43 pushes the main grinding ring 25 or the secondary grinding ring 35, and the main grinding ring 25 and the secondary grinding ring 35 will slide on the main limiting plate 23 and the secondary limiting plate 33 respectively. At the same time, the first spring 26 and the second spring 36 begin to be compressed. When the actuating wheel 43 rotates past the boss 42, the first spring 26 and the second spring 36 drive the main grinding ring 25 and the secondary grinding ring 35 to reset to one side. At the same time, the shift fork 41 will be pushed back to its initial position by the main grinding ring 25 and the secondary grinding ring 35. Then, while the secondary grinding ring 35 and the main grinding ring 25 rotate, they reciprocate to both sides. At the same time, the entire device moves along the bending direction of the pipe clamp, which can grind both the inner and outer sides of the pipe clamp at the same time, thereby improving the entire grinding range.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
