Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped pipe processing, in particular to a special-shaped pipe surface treatment device. Background Art

[0002] Pipelines currently play a vital role in various industries, so the surface treatment of steel pipes is a key factor in determining their service life. It is crucial for the anti-corrosion coating to remain firmly bonded to the steel pipe. Research institutions have confirmed that the lifespan of the anti-corrosion coating depends on the type of coating, the quality of the application, and the application environment. Surface treatment alone accounts for approximately 50% of the lifespan. This demonstrates the importance of surface treatment. Traditional methods for rust removal on steel pipes generally include cleaning, tool derusting, pickling, and mechanical equipment. When using tools for rust removal, a rotary derusting method, while conveying and polishing, is effective and fast for standard round pipes. However, for irregular P-type pipes, which cannot be rotated, this rotary derusting method is unsuitable, necessitating manual cleaning, which is slow, ineffective, and expensive.

[0003] Therefore, it is necessary to design a special-shaped tube surface treatment device to address the shortcomings of the existing technology, which can quickly and efficiently perform automated treatment on the surface of the P-type tube. Utility Model Content

The lower grinding wheel is fixedly arranged on the horizontal shaft.

[0008] As an improvement to the above solution, the side grinding mechanism includes a second frame, side grinding wheels, a first motor and a tensioning wheel. The second frame is arranged on the upper end of the conveyor. The tensioning wheel is arranged on one side of the second frame. There are two side grinding wheels, which are respectively connected to one of the pulleys of the tensioning wheel. The first motor is arranged on the second frame and is in transmission connection with the tensioning wheel.

The third frame is provided with a threaded hole adapted to the adjusting rod. The threaded hole is communicated with the chute. One end of the adjusting rod is rotatably and slidably mated with the blind hole on the slider. The first spring is sleeved on the adjusting rod. The two ends of the first spring respectively abut against the inner side wall of the chute and the slider.

[0010] As an improvement to the above solution, it further includes a pre-tightening mechanism. The pre-tightening mechanism includes a fourth frame, a cylinder, a connecting plate, sliding rods, a second spring and a pressing roller. The fourth frame is arranged on one side of the conveyor.

Detailed implementation manners

[0028] The above scheme will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0029] Embodiment 1

[0030] A special-shaped pipe surface treatment device, as Figures 1-5 shown, includes a conveyor 1. The conveyor 1 is used to convey the special-shaped pipe from one end to the other end. In this embodiment, the conveyor 1 adopts a roller conveyor. Along the conveying direction, multiple material conveying and limiting mechanisms 5 are further arranged at the upper end of the frame of the conveyor 1. The material conveying and limiting mechanisms 5 perform longitudinal limiting on the special-shaped pipe to make it convey along a predetermined route. For specific reference, see Figure 1 and Figure 5, the material transfer limiting mechanism 5 includes the third rack 51, limiting wheels 52, the second motor 53, slider 54, the first spring 55 and adjusting rod 56. Among them, the third rack 51 is fixedly arranged at the upper end of the rack of the conveyor 1. There are two limiting wheels 52, which are arranged perpendicular to the conveying direction of the conveyor 1. The gap between the two limiting wheels 52 is used for the special-shaped pipe to pass through and be aligned for limiting. Specifically, one of the limiting wheels 52 is rotatably connected to the third rack 51, and the second motor 53 is also connected to the bottom of this limiting wheel 52. When the second motor 53 drives this limiting wheel 52 to rotate, it can also assist the conveyor 1 in material transfer. The second motor 53 is fixedly connected to the third rack 51 through the motor bracket; the other limiting wheel 52 is rotatably connected to the slider 54. There is a chute on the third rack 51, and this chute is adapted to the slider 54. In addition, there is a threaded hole on one side of the third rack 51, and the threaded hole communicates with the chute. The surface of the adjusting rod 56 has an external thread. The adjusting rod 56 passes through the threaded hole provided on the third rack 51 and is in threaded cooperation with this threaded hole. One side of the slider 54 facing the threaded hole has a blind hole, and the end of the adjusting rod 56 is rotatably and slidably connected to this blind hole. The first spring 55 is sleeved on the adjusting rod 56, and the two ends of the first spring 55 respectively abut against the inner side wall of the chute and the slider 54. The material transfer limiting mechanism 5 can not only assist in material transfer, but also longitudinally limit the special-shaped pipes being processed, and the distance between the two limiting wheels 52 can be adjusted adaptively, which can be applicable to pipes of multiple sizes and specifications.

[0031] For specific reference Figures 1-2 , the upper grinding mechanism 2 is arranged at the upper end of the conveyor 1 and is used for grinding the upper surface of the special-shaped pipe. The upper grinding mechanism 2 includes the first rack 21, linear slide rail platform 22, driving mechanism 23, transmission shaft 24, stepped grinding wheel 25 and vertical support plate 26. The first rack 21 is fixedly arranged on the side of the conveyor 1 to support this mechanism. The linear slide rail platform 22 is fixedly arranged on the upper end surface of the first rack 21. The linear slide rail platform 22 includes a guide rail, a base, a slider and a driving cylinder. This is prior art and will not be elaborated here. The driving mechanism 23 is arranged on the slider of the linear slide rail platform 22. In this embodiment, the driving mechanism is a servo motor. Figure 2 and 3 As shown, one end of the spline shaft 241 is connected to the driving mechanism 23 through a coupling. The spline sleeve 242 is rotatably arranged on the vertical support plate 26. The spline sleeve 242 is nestedly connected to the spline shaft 241. The stepped grinding wheel 25 is installed on the spline shaft 241. The lower end of the vertical support plate 26 is fixedly connected to the side of the conveyor 1. For reference Figure 2, a lower grinding mechanism 3 is set at the lower end of the vertical support plate 26, and the lower grinding mechanism 3 includes a horizontal shaft 31 and a lower grinding wheel 32. The horizontal shaft 31 is rotatably set at the lower end of the vertical support plate 26, and the horizontal shaft 31 is connected to the spline sleeve 242 through a pulley group 27. The lower grinding wheel 32 is fixed on the horizontal shaft 31. The step grinding wheel 25 and the lower grinding wheel 32 grind the upper and lower surfaces of the special-shaped pipe respectively. The shape of the step grinding wheel 25 is two coaxial grinding wheels with different radii that fit each other. It is mainly used to adapt to the irregular shape of the upper surface of the p-type special-shaped pipe. In addition, an independent side grinding mechanism 4 is also provided. The linear slide platform 22 can drive the driving mechanism 23 and the transmission shaft 24 to move longitudinally and transversely, and finally drive the step grinding wheel 25 to adjust the position. During this period, the spline sleeve 242 and the spline shaft 241 slide relative to each other. Due to the special transmission relationship between the spline sleeve 242 and the spline shaft 241, it does not affect the operation of the lower grinding mechanism 3. Reference Figure 4 The side grinding mechanism 4 is arranged at the upper end of the conveyor 1 and is used to grind the side surface of the special-shaped pipe. The side grinding mechanism 4 includes a frame 2 41, a side grinding wheel 42, a tensioning wheel 44 and a first motor 43. The frame 2 41 is arranged at the upper end of the conveyor 1 and is used to support the mechanism. The tensioning wheel 44 is arranged at the bottom side of the frame 2 41. The tensioning wheel 44 is a prior art. In actual application, tensioning wheels of different structures can be selected according to the situation. There are two side grinding wheels 42, which are respectively connected to one of the pulleys of the tensioning wheel 44. The first motor 43 is arranged on the frame 2 41 and is connected to the tensioning wheel 44 in a transmission manner. The provision of the tensioning wheel can adjust the distance between the grinding wheels 42 on both sides and can adapt to a variety of pipe materials. The present utility model solves the problem that traditional P-type special-shaped pipes cannot be polished by a rotary grinder. The present utility model can realize automatic polishing of the surface of the P-type special-shaped pipe, and has a fast polishing speed, stable operation and good rust removal effect.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that

The pre-tightening mechanism 6 includes a frame 4 61, a cylinder 62, a connecting plate 63, a slide 64, a spring 2 65 and a pressure roller 66. The frame 4 61 is set on one side of the conveyor 1, the cylinder 62 is set on the frame 4 61, the connecting plate 63 is set on the piston rod of the cylinder 62, and there are two slides 64. The slides 64 are slidably set on both sides of the connecting plate 63. Each slide 64 is sleeved with a spring 2 65, and the pressure roller 66 is rotatably connected to the two slides 64. The pre-tightening mechanism can cooperate with the conveyor to press the pipe to avoid displacement caused by shaking during grinding, thereby affecting the grinding effect. The number of pre-tightening mechanisms 6 can be appropriately increased or decreased according to the length of the conveyor.

The bristles point downward towards the central axis of the shell. The brush is located on the transmission path of the special-shaped pipe, and the processed special-shaped pipe can be cleaned in all directions when passing through the brush.
